# Game ini files

The game ini files determine many aspects of the game, such as the names of the characters, the order of the lessons, and what characters do during lessons.

By default, the ini files for a particular game are arranged in one of the subdirectories of the ini directory thus:

- command_lists.ini - command lists
- config.ini - configuration parameters
- font.ini - font character bitmap descriptions (see [Font])
- lessons.ini - the main timetable and lessons
- messages.ini - messages
- skool.ini - walls, floors and other parts of the skool
- sprites.ini - sprite and character definitions

However, this arrangement is quite arbitrary; Pyskool will read every file with a .ini suffix in the subdirectory regardless of its name or contents. So you could, if you wish, concatenate all the ini files into one large ini file, and Pyskool will still work.

Pyskool reads ini files in alphabetical order of filename, and if a particular section appears in more than one file, the contents of that section in the last file read take precedence. So the best way to modify a game is to add customised sections to a file named zzz-custom.ini (for example), which will be read after all the stock ini files.

If you want to customise a section by adding lines to it rather than completely replacing the existing contents, you can append a ‘+’ to the section name. For example, if zzz-custom.ini contains a section named [SkoolLocations+], then the contents of that section will be appended to the contents of the [SkoolLocations] section defined in config.ini. By this method, you can customise the [SkoolLocations] section in a supplementary ini file without copying its original contents first.

What follows is a description of every section of the ini files. Armed with this knowledge, and by consulting the command reference where necessary, you’ll be able to start mucking around with how Pyskool works and how the game characters behave.

If you can’t be bothered to read any of this and instead just want to get your modding hands dirty right now, head over to Example customisations.

If you’re even lazier than that, head over to the ready-made customisations that are distributed with Pyskool.

## [AnimationPhases ...]

The `AnimationPhases ...` section names take the form:

    AnimationPhases phaseSetId

where `phaseSetId` is a descriptive unique ID for the list of animation phases that follows.

The format of an animation phase depends on who uses the phase set.

Each phase in the phase sets used by the frog (`FrogTurnRound`, `FrogShortHop` and `FrogLongHop`) looks like this:

    animatoryState, xInc, directionChange

where:

- `animatoryState` is the ID of the animatory state
- `xInc` is the x-coordinate increment
- `directionChange` is the direction multiplier (-1 to change direction, 1 to not)

Each phase in the phase sets used by Eric (`DescentMiddleWindow`, `DescentUpperWindow`, `ClimbSkoolGate` and `FlyOverSkoolGate`) looks like this:

    xInc, yInc, animatoryState

where:

- `xInc` is the x-coordinate increment
- `yInc` is the y-coordinate increment
- `animatoryState` is the ID of Eric’s animatory state

Each phase in the phase set used by the stream of water or sherry fired from a water pistol (`Water`) looks like this:

    animatoryState, xInc, yInc, hit

where:

- `animatoryState` is the ID of the animatory state
- `xInc` is the x-coordinate increment
- `yInc` is the y-coordinate increment
- `hit` is 0 if the water cannot hit anything, 1 if it can hit a cup, or 2 if it can hit a plant or the ground in this phase

Each phase in the phase set used by a stinkbomb when dropped (`Stinkbomb`) looks like this:

    animatoryState, direction

where:

- `animatoryState` is the ID of the animatory state
- `direction` is the direction (-1 for left, 1 for right)

## [AssemblyMessages]

The `AssemblyMessages` section contains all the information required to build a message used by the headmaster during assembly.

There are two types of entry in this section. The first type of entry is the message template entry:

    MESSAGE, assemblyMessageTemplate

which defines the template for an assembly message. The section can contain one or more message templates.

The second type of entry is the macro replacement entry:

    MACRO, text

where `MACRO` is the name of a macro that appears in a message template (prefixed by `$`), and `text` is the text to which the macro should expand. Multiple macro replacement entries may be defined for any given macro. When an assembly message is created, the message template is chosen at random, and the macro replacements are chosen at random.

In the stock Pyskool ini files, there is only one assembly message template, which contains two macros (`$VERB` and `$NOUN`).

## [Bike]

The `Bike` section contains a single line of the form:

    bikeId, spriteGroupId, animatoryState, unchainXY, commandListId, topLeft, size, coords, moveDelay, pedalMomentum, maxMomentum

where:

- `bikeId` is the bike’s ID
- `spriteGroupId` is the ID of the sprite group to use for the bike
- `animatoryState` is the bike’s initial animatory state
- `unchainXY` is the bike’s initial coordinates (in (x, y) form) after being unchained
- `commandListId` is the unique ID of the command list that the bike will use
- `topLeft` is the coordinates (in (x, y) form) of the top left of the image of the base of the tree with no bike attached
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the mutable image in the play area
- `moveDelay` is the delay between consecutive movements of the bike when wheeling along or being pedalled (the higher the number, the slower the bike will go)
- `pedalMomentum` is the momentum increment when the bike is pedalled
- `maxMomentum` is the maximum momentum the bike can have

The bike images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the image of the bike attached to the base of the tree is at (x + width, y), where (x, y) are the coordinates of the image of the base of the tree with no bike attached. These two images are the same size.

## [BlackboardMessages ...]

The `[BlackboardMessages ...]` section names take the form:

    BlackboardMessages characterId

where `characterId` is the unique ID of a character (see [Characters]).

Each `BlackboardMessages` section contains a list of messages (one per line) that may be written on a blackboard by the character whose ID is `characterId`.

There are two special characters used in blackboard messages: `^` and `$`. `^` represents the newline character (as defined by the `Newline` configuration parameter in the [MessageConfig] section). `$` is used to prefix the unique ID of a character, as in:

    TEARAWAY, i hate^$WACKER

where `$WACKER` will be replaced by whatever name has been given to the character whose unique ID is `WACKER`.

If no blackboard messages are defined for a particular character, that character will never write on a blackboard.

## [Blackboards]

The `Blackboards` section defines the blackboards in the classrooms. Each line has the form:

    roomId, topLeft, size, chalk

where:

- `roomId` is the classroom’s unique ID (see [Rooms])
- `topLeft` is the coordinates of the top-left of the blackboard
- `size` is the size (width, height) of the blackboard
- `chalk` is the chalk colour (as an RGB triplet) to use when writing on the blackboard

In the stock Pyskool ini files, `chalk` is set to (255, 255, 255) - bright white - which coincides with the transparent colour used in the skool ink image (see `SkoolInkKey` in the [ScreenConfig] section). This means that in graphics mode 1 (see `GraphicsMode` in the [ScreenConfig] section), anything written on the board will take on the background (paper) colour, which is how blackboards worked in the original games.

## [CatapultPellets]

Each line in the `CatapultPellets` section has the form:

    characterId, pelletId, spriteGroupId, commandListId, range, hitZone, hitXY

where:

- `characterId` is the unique ID of the catapult-wielding character
- `pelletId` is the unique ID of the catapult pellet
- `spriteGroupId` is the ID of the sprite group to use for the pellet
- `commandListId` is the unique ID of the command list that the pellet will use
- `range` is the distance the pellet will fly after being launched
- `hitZone` is the size of the interval at the end of the pellet’s flight where it can knock a character over
- `hitXY` is the coordinates of the pellet within its sprite (used for collision detection)

Each character whose unique ID appears in this section will be fitted out with a catapult. In the stock Pyskool this will be Eric and the tearaway - the only characters with catapult-firing sprites.

## [Chairs]

The `Chairs` section contains one line for each classroom in the skool. Each line has the form:

    roomId, x1, x2, x3..., xN

where:

- `roomId` is the classroom’s unique ID (see [Rooms])
- `x1`, `x2`, `x3` and so on are the x-coordinates of the chairs in the classroom

The order in which the x-coordinates are listed is significant: `x1` should correspond to the ‘front seat’ and `xN` should correspond to the ‘back seat’. So if `x1` < `xN`, characters will sit down facing left; if `x1` > `xN`, characters will sit down facing right.

## [Characters]

Each line in the `Characters` section has the form:

    characterId, name[/title], spriteGroupId, animatoryState, direction, (x, y), headXY, flags

and corresponds to a single character, where:

- `characterId` is the character’s unique ID (which should be alphanumeric and is used to refer to the character in other parts of the ini file)
- `name` is the character’s name (as displayed in the game), and `title` (if supplied) is the name used by the swot to address the character
- `spriteGroupId` is the ID of the sprite group to use for the character
- `animatoryState` is the character’s initial animatory state
- `direction` is the character’s initial direction (-1 for left, 1 for right)
- `(x, y)` are the character’s initial coordinates
- `headXY` are the coordinates of the character’s head within his sprite when he’s standing upright (used for collision detection)
- `flags` is a string of flags defining the character’s abilities and vulnerabilities

Recognised flags and their meanings are:

- `A` - is an adult
- `B` - belongs in the boys’ skool
- `C` - can be knocked over by a conker (see also `Z`)
- `D` - can open doors and windows
- `F` - can be knocked out by a fist
- `G` - belongs in the girls’ skool
- `K` - holds the key to the safe
- `L` - can give lines
- `M` - is scared of mice
- `N` - can smell stinkbombs (and will open a nearby window if possible)
- `P` - can be knocked over by a catapult pellet
- `R` - can receive lines
- `S` - holds a safe combination letter
- `T` - can be tripped up by a stampeding kid (see TripPeopleUp)
- `U` - lines received by this character will be added to Eric’s total
- `V` - lines received by this character will be added to Eric’s score
- `W` - usually walks (unlike kids who sometimes run)
- `X` - holds a bike combination digit
- `Y` - holds a storeroom door combination letter
- `Z` - will be temporarily paralysed if struck by a falling conker (see also `C`)

## [CommandList ...]

The `[CommandList ...]` section names take the form:

    CommandList commandListId

where `commandListId` is a descriptive unique ID for the list of commands that follows. These unique IDs are used in the [Lesson ...] sections: for each type of lesson there is, every character is assigned a single command list to follow.

One example of a command list is:

    [CommandList Walkabout1-Wacker]
    GoTo, HeadsStudy:Window
    GoToRandomLocation
    Restart

This command list is used occasionally by the headmaster; it makes him repeatedly go to one of his random locations and then back to his study.

Each line in a command list contains the command name followed by a comma-separated list of arguments. See the command reference for more details on the commands that may be used to control a character.

## [Conker]

The `Conker` section defines a conker (as knocked out of the tree by a catapult pellet). It contains a single line of the form:

    objectId, spriteGroupId, commandListId, minX, maxX, minY, maxY, hitXY

where:

- `objectId` is a unique ID for the conker
- `spriteGroupId` is the ID of the sprite group to use for the conker
- `commandListId` is the unique ID of the command list that the conker will use when knocked out of the tree
- `minX`, `maxX`, `minY` and `maxY` define the rectangle inside the tree that contains the conker; a pellet that hits a spot in that rectangle will cause a conker to fall
- `hitXY` is the coordinates of the conker within its sprite (used for collision detection)

## [Cups]

The `Cups` section contains information about cups. Each line describes a single cup, and has the form:

    cupId, emptyTopLeft, size, coords

where:

- `cupId` is the unique ID of the cup
- `emptyTopLeft` is the coordinates (in (x, y) form) of the top left of the image of the cup when empty
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the cup in the skool

The cup images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the image of a cup when it contains water is at (x + width, y), and the image of a cup when it contains sherry is at (x + 2 * width, y) (where (x, y) are the coordinates of the image of the cup when empty). The three images for any given cup are the same size.

## [DeskLid]

The `DeskLid` section contains a single line of the form:

    deskLidId, spriteGroupId, commandListId, xOffset

where:

- `deskLidId` is the unique ID of the desk lid
- `spriteGroupId` is the ID of the sprite group to use for the desk lid when raised
- `commandListId` is the unique ID of the command list that the desk lid will use
- `xOffset` - the offset (relative to the desk being opened) at which the desk lid should be displayed

## [Desks]

Each line in the `Desks` section has the form:

    roomId, x1, x2...

where

- `roomId` is a classroom’s unique ID (see [Rooms])
- `x1`, `x2` and so on are the x-coordinates of the desks in the classroom (which should be a subset of the x-coordinates of the chairs in the classroom - see [Chairs])

Any chair that is in a room and at an x-coordinate that appears in the `Desks` section will be fitted out with a desk lid that can be raised (see [DeskLid]).

## [Doors]

The `Doors` section contains details of the doors in the game. Each line has the form:

    doorId, x, bottomY, topY, initiallyShut, autoShutDelay, shutTopLeft, size, coords[, climb[, fly]]

where:

- `doorId` is the door’s unique ID
- `x` is the door’s x-coordinate
- `bottomY` and `topY` are the y-coordinates of the bottom and top of the door
- `initiallyShut` is `Y` if the door should be shut when the game starts
- `autoShutDelay` is the delay before the door swings shut automatically; if zero or negative, the door will not shut automatically
- `shutTopLeft` is the coordinates (in (x, y) form) of the top left of the image of the door when shut
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the door in the skool
- `climb` is the ID of the sequence of animation phases to use for Eric if he climbs over the door when it’s shut; if not defined, Eric will not be able to climb over the door
- `fly` is the ID of the sequence of animation phases to use for Eric if he flies over the door after hitting it while standing on the saddle of the bike; if not defined, Eric will not be able to fly over the door

The door images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the image of a door when open is at (x + width, y), where (x, y) are the coordinates of the image of the same door/window when shut. The open/shut images for any given door are the same size.

## [Eric]

The `Eric` section describes our hero, Eric. It contains a single line in the format:

    characterId, name, spriteGroupId, animatoryState, direction, (x, y), headXY, flags[, bendOverHandXY]

where:

- `bendOverHandXY` is the coordinates of Eric’s hand within his left-facing BENDING_OVER sprite (used to determine where a mouse or frog should be when caught or released)

For a description of the available flags, see [Characters].

## [Font]

The `Font` section is used to determine the location and size of the font character bitmaps in the font.png graphic. Each line has the form:

    "char", offset, width

where:

- `char` is the font character (e.g. `f`, `@`, `!`)
- `offset` is the font character’s distance in pixels from the left of the image
- `width` is its width in pixels

## [Floors]

The `Floors` section contains details of the “floors” in the skool. A “floor” (note the quotes) is a region of the skool that cannot be reached from another region of the skool without navigating a staircase. For example, in Skool Daze, the region to the left of the Map Room wall is one floor, and the region to the right of the Map Room wall is another floor. You can’t get from one to other without going up or down a staircase (walking through walls is prohibited).

Each line in this section has the form:

    floorId, minX, maxX, y

where:

- `floorId` is the floor’s unique ID
- `minX` and `maxX` are the x-coordinates of the left and right limits of the floor
- `y` is the y-coordinate of the floor (3 = top floor, 10 = middle floor, 17 = bottom floor)

The unique IDs are used in the [Routes] section.

## [Frogs]

Each line in the `Frogs` section has the form:

## [GrassMessages]

The `GrassMessages` section contains five lines of the form:

    Writers, characterId[, characterId...]
    WriteTale, <text>
    Hitters, characterId[, characterId...]
    HitTale, <text>
    AbsentTale, <text>

The information in this section is used by the swot to determine who can be blamed for hitting him or writing on a blackboard, and what to say when telling tales.

The `Writers` line contains a comma-separated list of IDs of characters who can be blamed for writing on a blackboard. The `WriteTale` line contains the text of the blackboard-writing tale.

The `Hitters` line contains a comma-separated list of IDs of characters who can be blamed for hitting the swot. The `HitTale` line contains the text of the so-and-so-hit-me tale.

The `AbsentTale` line contains the text that will be spoken by the swot when he’s telling on Eric for being absent during class.

The text of a tale may contain any of the following macros:

- `$TITLE` - which will be replaced by the teacher’s title, as defined in the [Characters] section; to change this macro, set the `TitleMacro` configuration parameter in the [MessageConfig] section
- `$1` - which will be replaced by the name of the hitter or writer chosen from the `Hitters` or `Writers` list; to change this macro, set the `GrasseeMacro` configuration parameter in the [MessageConfig] section

## [Images]

Each line in the `Images` section has the form:

    imageId, path

where

- `imageId` is the unique ID of an image

- `STINKBOMBS1` - one stinkbomb
- `STOREROOM_KEY` - the key to the science lab storeroom
- `WATER_PISTOL` - a water pistol (containing water)

The order in which the items appear in the `Inventory` section determines the order in which they will be printed in the on-screen inventory.

See also the [Mice] and [Frogs] sections (for details on those animals), and the `InventoryPos` and `MouseInventoryPos` configuration parameters in the [ScreenConfig] section.

## [Lesson ...]

The `[Lesson ...]` section names take the form:

    Lesson lessonId [*]characterId, roomId

if the lesson will take place with a teacher in a classroom or the dinner hall, or:

    Lesson lessonId locationId

if the lesson is an unsupervised period, where:

- `lessonId` is the lesson ID as it appears in the [Timetable] section
- `characterId` is the character ID of the teacher taking Eric’s class (prefixed by ‘*’ if the teacher’s name should not be printed in the lesson box, as during `DINNER`)
- `roomId` is the ID of the room in which Eric’s class will take place
- `locationId` is one of `PLAYTIME`, `REVISION LIBRARY`, and `ASSEMBLY`

Each line in a `[Lesson ...]` section has the form:

    characterId, commandListId

where

- `characterId` is the unique ID of a character (see [Characters])
- `commandListId` is the ID of the command list that will control the character’s movements during the lesson

A command list is a sequence of commands - such as GoTo or FindSeat - that make a character appear intelligent (kind of). See [CommandList ...] for more details.

In any `[Lesson ...]` section there should be one line for each character defined in the [Characters] section.

## [LessonConfig]

The `LessonConfig` section contains configuration parameters in the format:

    parameterName, parameterValue

Recognised parameters are:

- `BlackboardBacktrack` - the distance a teacher walks back after wiping a blackboard
- `BlackboardPaceDistance` - the distance a teacher should pace up and down in front of the blackboard during a lesson without a question-and-answer session
- `EricsTeacherWriteOnBoardProbability` - the probability that a teacher will write on the blackboard during a lesson with Eric and the swot
- `GrassForHittingProbability` - the probability that the swot will grass on someone for hitting him
- `LinesForTalesProbability` - the probability that the teacher will give the swot lines for telling tales
- `QASessionProbability` - the probability that the teacher will start a question-and-answer session with the swot
- `WriteOnBoardProbability` - the probability that a teacher will write on the blackboard during a lesson without Eric and the swot

## [LessonMessages]

The `LessonMessages` section contains a list of messages that will be used by teachers who are not teaching Eric, or teachers who are teaching Eric but have chosen not to do a question-and-answer session. Each line in the section takes the form:

    characterId|*, lessonMessage[, condition]

where:

- `characterId` is the unique ID of a teacher
- `lessonMessage` is the message to add to that teacher’s repertoire
- `condition` is a condition identifier that must evaluate to true before the message can be used

If `*` is used instead of a specific character ID, the message will be placed in every teacher’s repertoire.

A lesson message may contain a character sequence `$(N, M)` (where N and M are numbers); if so, it will be replaced by a random number between N and M.

The only recognised condition identifier is:

- `BoardDirty`

(as defined by the `BoardDirtyConditionId` parameter in the [MessageConfig] section) which, if specified, means the message will be used only if the blackboard (if there is one) has been written on. Any other condition identifier will evaluate to true.

## [LinesMessages]

The `LinesMessages` section contains a list of admonitions delivered by lines-givers when Eric has been spotted doing something he shouldn’t. Each line in this section has the form:

    characterId|*, linesMessageId, linesMessage

where

- `characterId` is the unique ID of the lines-giving character
- `linesMessageId` is the unique ID of the following message
- `linesMessage` is the admonition itself

If `*` is used instead of a character ID, the lines message will be used by all lines-givers (unless they have been explicitly assigned a lines message with the same lines message ID). For example:

    WITHIT, NO_HITTING, BE GENTLE^NOW
    *, NO_HITTING, DON'T HIT^YOUR MATES

would make Mr Withit scream “BE GENTLE NOW” whenever he sees Eric throwing a punch, whereas every other teacher would scream “DON’T HIT YOUR MATES” instead.

A lines message always spans two lines on-screen. A caret (`^`) is used by default to indicate where the words should be wrapped; to change this, set the `Newline` configuration parameter in the [MessageConfig] section.

The recognised lines message IDs are:

- `BACK_TO_SKOOL` - Eric should be back in the boys’ skool by now
- `BE_PUNCTUAL` - Eric was late for class
- `COME_ALONG_1` - the truant Eric is being guided to the classroom
- `COME_ALONG_2` - the truant Eric is still being guided to the classroom
- `COME_ALONG_3` - the truant Eric still hasn’t made it to the classroom
- `GET_ALONG` - Eric is not in class when he should be
- `GET_OFF_PLANT` - Eric is standing on a plant
- `GET_OUT` - Eric is somewhere that only staff are allowed to be
- `GET_UP` - Eric is sitting on the floor
- `NEVER_AGAIN` - a teacher thinks Eric knocked him down
- `NO_BIKES` - Eric is riding a bike inside the skool
- `NO_CATAPULTS` - Eric is firing a catapult
- `NO_HITTING` - Eric is throwing a punch
- `NO_JUMPING` - Eric is jumping
- `NO_SITTING_ON_STAIRS` - Eric is sitting on the stairs
- `NO_STINKBOMBS` - Eric has dropped a stinkbomb
- `NO_TALES` - the swot gets his just deserts
- `NO_WATERPISTOLS` - Eric is firing a water pistol
- `NO_WRITING` - Eric is writing on a blackboard
- `SIT_DOWN` - Eric is standing up in class
- `SIT_FACING_STAGE` - Eric is not facing the headmaster during assembly
- `STAY_IN_CLASS` - Eric popped out of class and then returned

The lines message IDs are used internally, and should not be changed. If a particular lines message ID is missing from the list, then lines will not be given for the infraction it refers to. So if there were no entry in the `LinesMessages` section with the lines message ID `NO_HITTING`, no lines would ever be dished out for hitting.

## [MessageConfig]

The `MessageConfig` section contains messages and message-related configuration parameters that apply skool-wide. Each line in this section has the form:

    parameterName, parameterValue

Recognised parameters are:

- `BoardDirtyConditionId` - the ID of the condition used to indicate that a blackboard is dirty; this identifier may be used in the [LessonMessages] section
- `GrasseeMacro` - the macro that expands to a grassee’s name in the swot’s speech
- `HiScoreLabel` - the label for the hi-score in the score box
- `LinesMessageTemplate` - the template used for lines messages
- `LinesRecipientMacro` - the macro that will be replaced in `LinesMessageTemplate` (see above) by the lines recipient’s name
- `LinesTotalLabel` - the label for the lines total in the score box
- `Newline` - the character that will be replaced by a newline character in messages written on a blackboard, in a lines bubble, or in the lesson box
- `NumberOfLinesMacro` - the macro that will be replaced in `LinesMessageTemplate` (see above) by the number of lines being given
- `ScoreLabel` - the label for the score in the score box
- `TitleMacro` - the macro that expands to a teacher’s title in the swot’s speech
- `UpAYearMessage` - the message printed in the lesson box when Eric has completed the game and advanced a year

## [Mice]

Each line in the `Mice` section has the form:

    mouseId, spriteGroupId, animatoryState, (x, y), commandListId, spriteXY

where:

- `mouseId` is the unique ID of the mouse
- `spriteGroupId` is the ID of the sprite group to use for the mouse
- `animatoryState` is the mouse’s initial animatory state
- `(x, y)` are the mouse’s initial coordinates
- `commandListId` is the ID of the command list that the mouse will use
- `spriteXY` is the coordinates of the mouse within its sprite (used for detecting whether Eric has caught it)

Any mouse defined in this section will be catchable by ERIC, and show up in the on-screen mouse inventory when caught.

## [MouseLocations]

The `MouseLocations` section defines the locations at which a new immortal mouse may appear after Eric catches one. Each line has the form:

    x, y

where `(x, y)` are the coordinates of the location.

## [NoGoZones]

Each line in the `NoGoZones` section corresponds to a region of the skool Eric is never supposed to enter. The lines take the form:

    zoneId, minX, maxX, bottomY, topY

where:

- `zoneId` is a descriptive ID for the zone (not used anywhere else)
- `minX` is the lower x-coordinate of the zone
- `maxX` is the upper x-coordinate of the zone
- `bottomY` is the y-coordinate of the bottom of the zone
- `topY` is the y-coordinate of the top of the zone

Whenever Eric is spotted in one of these zones by a teacher, the `GET_OUT` lines message will be delivered in screeching tones.

## [Plants]

The `Plants` section contains information about plants. Each line describes a single plant, and has the form:

    plantId, spriteGroupId, x, y, commandListId

where:

- `plantId` is the unique ID of the plant
- `spriteGroupId` is the ID of the sprite group to use for the plant
- `x` and `y` are the coordinates of the plant (when it is growing or has grown)
- `commandListId` is the unique ID of the command list that the plant will use when watered

## [QuestionsAndAnswers ...]

The `[QuestionsAndAnswers ...]` section names take the form:

    QuestionsAndAnswers characterId

where `characterId` is the unique ID of a teacher (see [Characters]).

There are at least three types of entry in a `[QuestionsAndAnswers ...]` section. The first type of entry is the `Question` entry:

    Question, questionId, groupId, questionTemplate

where:

- `questionId` is a unique (within the section) ID for the question
- `groupId` is the ID of the group of Q&A pairs (see below) the question is associated with
- `questionTemplate` is the question template

There should be at least one `Question` entry in a `[QuestionsAndAnswers ...]` section.

The second type of entry is the `Answer` entry:

    Answer, questionId, answerTemplate

where:

- `questionId` is the ID of the question to which this is the answer
- `answerTemplate` is the answer template

There should be one `Answer` entry for each `Question` entry in a `[QuestionsAndAnswers ...]` section.

The third type of entry in this section is the Q&A pair entry:

    groupId, word1, word2

where

- `groupId` is the ID of the group of Q&A pairs to which this particular pair belongs; the ID should be something other than Question, Answer, SpecialGroup, SpecialQuestion or SpecialAnswer, which are reserved words in a `[QuestionsAndAnswers ...]` section
- `word1` and `word2` are the words that will replace the macros in `questionTemplate` and `answerTemplate`

There should be at least one Q&A pair defined per `[QuestionsAndAnswers ...]` section (and ideally many more than one, to prevent the question-and-answer sessions between teachers and the swot from being rather monotonous).

The optional fourth type of entry in a `[QuestionsAndAnswers ...]` section consists of three lines:

    SpecialQuestion, question
    SpecialAnswer, answer
    SpecialGroup, groupId, qaPairIndex

and is used to define the “special” question Eric will need the answer to in order to obtain the relevant teacher’s safe combination letter. The `SpecialQuestion` keyword is followed by the text of the special question (which will be posed by the teacher at the start of the lesson). The `SpecialAnswer` keyword is followed by the text of the swot’s answer to the special question (which will contain a macro to be expanded). The `SpecialGroup` keyword is followed by `groupId` (which specifies the ID of the group of Q&A Pairs from which the “magic word” will be taken), and `qaPairIndex` (which is 0 or 1, and refers to the element of the Q&A pair that will be the magic word). Once Eric has figured out what the magic word is, he will need to write it on a blackboard and hope that the teacher sees it, whereupon the teacher will reveal his safe combination letter.

If the `SpecialQuestion`, `SpecialAnswer` and `SpecialGroup` lines are not present, there will be no magic word associated with the teacher. In that case, simply knocking the teacher over with a catapult pellet will make him reveal his safe combination letter.

## [RandomLocations]

The `RandomLocations` section contains lists of suitable locations for the characters to visit when they go on walkabouts (e.g. during playtime). Each line has the form:

    characterId, (x1, y1), (x2, y2)...

where:

- `characterId` is the character’s unique ID (see [Characters])
- `(x1, y1)` and so on are the coordinates of locations in the skool

There must be at least one pair of coordinates per line, and there should be one line for each character defined in the [Characters] section.

## [Rooms]

The `Rooms` section contains one line for each room or region in the skool that Eric will be expected to show up at when the timetable requires it. Each line has the form:

    roomId, name, topLeft, bottomRight, getAlong

where:

- `roomId` is the room’s unique ID
- `name` is the room’s name (as displayed in the lesson box at the bottom of the screen)
- `topLeft` is the coordinates of the top-left corner of the room
- `bottomRight` is the coordinates of the bottom-right corner of the room
- `getAlong` is `Y` if Eric should get lines for being in the room when the timetable does not require his presence

## [Routes]

The `Routes` section is one of the most important sections in the ini file. It defines the routes (a route may be considered as a list of staircases) that the characters must take to get from where they are to wherever they are going. Any errors here will result in the characters wandering aimlessly around the skool, unable to find classrooms, the playground, or the toilets. Disaster!

Anyway, each line in this section has the form:

    homeFloorId, *|destFloorId[, destFloorId[, ...]], nextStaircaseId

where:

- `homeFloorId` is the unique ID of one floor (see [Floors]) - the ‘home’ floor
- `destFloorId` is the unique ID of another floor (see [Floors]) - the destination floor
- `nextStaircaseId` is the unique ID of the staircase (see [Staircases]) that must be climbed or descended first on a journey from the home floor to the destination floor

How this works is best illustrated by example. Let’s look at the routes defined for the bottom floor in Back to Skool to everywhere else in the skool:

    Bottom, LeftMiddle, LeftTop, UpToToilets
    Bottom, GirlsMiddle, GirlsTop, GirlsSkoolLower
    Bottom, *, UpToStage

The first line says that to get from the bottom floor (`Bottom`) to the floors called `LeftMiddle` and `LeftTop` (see [Floors]), the first staircase you need to navigate is `UpToToilets` (see [Staircases]). The second line says that to get from the bottom floor to the middle floor (`GirlsMiddle`) or top floor (`GirlsTop`) in the girls’ skool, you need to use the `GirlsSkoolLower` staircase first. The third line says that to get anywhere else (`*`) from the bottom floor, you need to take the stairs up to the stage (`UpToStage`).

## [Safe]

The `Safe` section contains a single line of the form:

    topLeft, size, coords

where:

- `topLeft` is the coordinates (in (x, y) form) of the top left of the normal image of the safe
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the safe in the play area

The safe images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the inverse image of the safe is at (x + width, y), where (x, y) are the coordinates of the normal image of the safe.

If the safe will never need to flash (as in Back to Skool), `topLeft` and `size` will not be used, and so may be set to any value.

## [ScreenConfig]

The `ScreenConfig` section contains parameters that determine the appearance and layout of the screen. Each line has the form:

    parameterName, parameterValue

Recognised parameters are:

- `Background` - the background colour of the screen
- `EscapeAlarmInk` - the ink colour to use for the escape alarm message box used by Albert
- `EscapeAlarmPaper` - the paper colour to use for the escape alarm message box used by Albert

- `InventorySize` - the size of the inventory (width and height in tiles)
- `LessonBoxInk` - the ink colour to use when writing in the lesson box
- `LessonBoxPos` - the x, y coordinates of the lesson box on screen
- `LinesInk` - the ink colour used in a lines message box
- `LinesOffset` - the y-coordinate offset used to position the printing of the lines total
- `LinesPaperEric` - the paper colour used in a lines message box when Eric is the recipient
- `LinesPaperOther` - the paper colour used in a lines message box when Eric is not the recipient
- `LogoPos` - the x, y coordinates of the logo on screen
- `MessageBoxColour` - the colour of the ‘inside’ of the message box in the `MESSAGE_BOX` image (see [Images]); pixels of this colour in the image will take on the designated paper colour (e.g. `LinesPaperEric`) when the message box is drawn
- `MessageBoxKey` - pixels of this colour in the message box image will be made transparent when the message box is drawn; in the stock Pyskool, this feature is not used
- `MouseInventoryInk` - the ink colour to use when writing in the mouse inventory
- `MouseInventoryPos` - the x, y coordinates of the mouse inventory on screen

- `ScoreOffset` - the y-coordinate offset used to position the printing of the score
- `ScrollFps` - the number of frames per second at which the screen should be scrolled (when the game starts and during play); raise it to make the screen scroll faster, or lower it to scroll more slowly
- `ScrollColumns` - the number of columns to scroll when Eric approaches the left or right edge of the screen
- `ScrollLeftOffset` - how close Eric can get to the right edge of the screen before it scrolls left
- `ScrollRightOffset` - how close Eric can get to the left edge of the screen before it scrolls right
- `SecretInk` - the ink colour of the message box used to display a safe, bike or storeroom combination character
- `SecretPaper` - the paper colour of the message box used to display a safe, bike or storeroom combination character

- `SpeechBubbleInk` - the ink colour to use when drawing text in a speech bubble
- `SpeechBubbleKey` - the transparent colour used in the speech bubble image (bubble.png)
- `SpeechBubbleInset` - the inset (in pixels at scale 1) of the text window from the top-left of a speech bubble
- `SpeechBubbleLipCoords` - the coordinates of the lip within the speech bubble image (bubble.png)

## [SherryDrop]

The `SherryDrop` section defines a drop of sherry (as knocked out of a cup by a catapult pellet). It contains a single line of the form:

    objectId, spriteGroupId, commandListId, hitXY

where:

- `objectId` is a unique ID for the drop of sherry
- `spriteGroupId` is the ID of the sprite group to use for the drop of sherry
- `commandListId` is the unique ID of the command list that the drop of sherry will use when knocked out of a cup
- `hitXY` is the coordinates of the sherry drop within its sprite (used for collision detection)

## [Shields]

The `Shields` section contains information about shields. Each line describes a single shield, and has the form:

    score, topLeft, size, coords

where:

- `score` is the number of points awarded for making the shield flash or unflash
- `topLeft` is the coordinates (in (x, y) form) of the top left of the normal image of the shield
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the shield in the play area

The shield images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the inverse image of a shield is at (x + width, y), where (x, y) are the coordinates of the normal image of the shield.

## [SitDownMessages]

The `SitDownMessages` section contains one or more lines for each teacher of the form:

    characterId, sitDownMessage

where

- `characterId` is the teacher’s unique ID (see [Characters])
- `sitDownMessage` is what the teacher may say while standing at the classroom doorway at the start of a lesson

If multiple sit-down messages are defined for a teacher, he will choose one at random when the time comes. If no sit-down messages are defined for a teacher, he will say nothing at the classroom doorway.

## [SkoolLocations]

The `SkoolLocations` section contains a list of descriptive IDs for commonly used locations in the skool. These descriptive IDs are used by the GoTo command in the command lists that control the characters. Each line in this section has the form:

    locationId, x, y

where

- `locationId` is the descriptive ID
- `x` and `y` are the coordinates of the location

An example of a location ID is `BlueRoomDoorway`, which means exactly what you think it means.

## [Sounds]

Each line in the `Sounds` section has the form:

    soundId, path

where

- `soundId` is the unique ID of a sound effect
- `path` is the location of the sound file on disk (relative to the sounds directory)

`path` may be the full name of the sound file (e.g. tune.wav), or just the base name (e.g. tune); in the latter case, Pyskool will look for a file with the base name and a .wav or .ogg suffix.

Recognised IDs and the sound effects they refer to are:

- `ALARM`: Albert is telling Mr Wacker that Eric is escaping
- `ALL_SHIELDS`: Eric has hit all the shields
- `BELL`: the bell
- `BIKE`: Eric has written the bike combination on a blackboard
- `CATAPULT`: Eric has fired his catapult
- `CONKER`: Eric has knocked out Albert with a conker
- `DESK`: Eric has found the water pistol or stinkbombs in a desk
- `FROG`: Eric has caught the frog or placed it in a cup
- `HIT0`, `HIT1`: Eric has thrown a punch
- `JUMP`: Eric has jumped into the air
- `KISS`: Eric has kissed someone
- `KNOCKED_OUT`: Eric has been knocked over or out of his chair
- `LINES1`: lines screech 1
- `LINES2`: lines screech 2
- `MOUSE`: Eric has caught a mouse
- `OPEN_SAFE`: Eric has opened the safe (by getting the combination)
- `SAFE_KEY`: Eric has got the safe key
- `SHERRY`: Eric has filled the water pistol with sherry
- `SHIELD`: Eric has hit a shield
- `STOREROOM_KEY`: Eric has written the storeroom combination on a blackboard
- `TUNE`: opening tune
- `UP_A_YEAR`: Eric has gone up a year
- `WALK0`, `WALK1`, `WALK2`, `WALK3`: Eric walking
- `WATER_PISTOL`: Eric has fired his water pistol

If an entry for a given sound effect is not present in the `Sounds` section, then that sound effect will never play. For example, if there is no `CATAPULT` entry, then Eric’s firings of that weapon will be completely silent.

## [SpecialPlaytimes]

The `SpecialPlaytimes` section contains a list of lesson IDs that refer to playtimes which will be considered “special”. A special playtime does not appear in the timetable proper (though you could insert it), but with a given probability (defined by the `SpecialPlaytimeProbability` parameter in the [TimetableConfig] section) a special playtime chosen at random is substituted for an actual playtime from the main timetable. In Skool Daze the `SpecialPlaytimes` section looks like this:

    Playtime-Mumps
    Playtime-SwotGrass
    Playtime-HiddenPeaShooter

Thus, occasionally in Skool Daze mode a playtime will be one of those where you have to steer clear of the pestilential bully, prevent the swot from reaching the head’s study, or fix the race to the fire escape between the tearaway and the headmaster.

## [SpriteGroup ...]

The `[SpriteGroup ...]` section names take the form:

    SpriteGroup spriteGroupId

where `spriteGroupId` is a unique ID for a group of sprites in sprites.png (see Graphics) - such as `BOY` for the little boys, or `TEARAWAY` for the tearaway. The unique ID can be anything you like; it is used only in the [Characters] section later on to link a character to a specific group of sprites.

Each line in a `SpriteGroup` section represents a single sprite from sprites.png and has the form:

    spriteId, index

where

- `spriteId` is the descriptive ID for the sprite (unique within the section)
- `index` is the index of the sprite as it appears in sprites.png

Recognised sprite IDs and their meanings are:

- `ARM_UP`: arm up (as if writing or opening door) - Eric, the tearaway, the Heroine and teachers
- `BENDING_OVER`: bending over - Eric
- `BIKE_ON_FLOOR`: bike resting on the floor
- `BIKE_UPRIGHT`: bike upright
- `CATAPULT0`: firing catapult (1) - Eric and the tearaway
- `CATAPULT1`: firing catapult (2) - Eric and the tearaway
- `CONKER`: conker
- `DESK_EMPTY`: desk lid (empty desk)
- `DESK_STINKBOMBS`: desk lid (with stinkbombs)
- `DESK_WATER_PISTOL`: desk lid (with water pistol)
- `FLY`: catapult pellet in flight
- `HITTING0`: hitting (1) - Eric and the bully

- `PLANT_GROWN`: plant (fully grown)
- `RIDING_BIKE0`: riding bike (1) - Eric
- `RIDING_BIKE1`: riding bike (2) - Eric
- `RUN`: mouse
- `SHERRY_DROP`: drop of sherry (knocked from a cup)
- `SIT`: frog sitting
- `SITTING_ON_CHAIR`: sitting on a chair - kids
- `SITTING_ON_FLOOR`: sitting on the floor - kids
- `STINKBOMB`: stinkbomb cloud
- `WALK0`: standing/walking (1) - all characters
- `WALK1`: midstride (1) - all characters
- `WALK2`: standing/walking (2) - all characters
- `WALK3`: midstride (2) - all characters
- `WATER_DROP`: drop of water (knocked from a cup)
- `WATER0`: water fired from a pistol (phase 1)
- `WATER1`: water fired from a pistol (phase 2)
- `WATER2`: water fired from a pistol (phase 3)
- `WATER3`: water fired from a pistol (phase 4)
- `WATER4`: water fired from a pistol (phase 5)
- `WATERPISTOL`: shooting water pistol - Eric

## [Staircases]

The `Staircases` section contains details of the staircases in the skool. Each line has the form:

    staircaseId[:alias], bottom, top[, force]

where:

- `staircaseId` is the staircase’s unique ID
- `alias` is an optional alias for the staircase (also unique)
- `bottom` and `top` are the coordinates of the bottom and top of the staircase (in (x, y) form)
- `force`, if present, indicates that the staircase must be climbed or descended by Eric if he moves to a location between the bottom and the top

In the stock Pyskool, `force` is used for the staircase in Back to Skool that leads down to the assembly hall stage; it’s the only staircase in the game that you must go up or down if you approach it.

An example of a line from the `Staircases` section is:

    UpToStudy:DownFromStudy, (91, 10), (84, 3)

which defines the staircase that leads up to the head’s study in Back to Skool. This staircase’s unique ID is `UpToStudy`, but it can also be referred to as `DownFromStudy`. These unique IDs and aliases are used in the [Routes] section.

## [Stinkbombs]

Each line in the `Stinkbombs` section has the form:

    characterId, stinkbombId, spriteGroupId, commandListId, animationPhases, stinkRange

where:

- `characterId` is the unique ID of the character to give stinkbomb-dropping ability to
- `stinkbombId` is the unique ID of the stinkbomb
- `spriteGroupId` is the ID of the sprite group to use for the stinkbomb when dropped
- `commandListId` is the unique ID of the command list that the stinkbomb will use when dropped
- `animationPhases` is the ID of the sequence of animation phases that the stinkbomb cloud will use
- `stinkRange` - the maximum distance at which the stinkbomb can be smelt

Each character whose unique ID appears in this section will be given the ability to drop a stinkbomb. In the stock Pyskool this will be Eric.

## [Timetable]

The `Timetable` section contains an ordered list of lesson IDs. Lessons happen starting with the first in the list, and proceed one by one to the end of the list. When the last lesson in the list is finished, the game loops back round to the first lesson in the list.

An example of a lesson ID is `Creak-BlueRoom-1`, which refers to the first of a set of lessons in which Eric and the swot are taught by Mr Creak in the Blue Room. The lesson ID could be anything, but it’s helpful to make it descriptive.

A lesson can be thought of as a set of entries from the personal timetables of the characters. These sets of entries can be found in the [Lesson ...] sections.

## [TimetableConfig]

The `TimetableConfig` section contains configuration parameters in the format:

    parameterName, parameterValue

Recognised parameters are:

- `AssemblyPrefix` - what a lesson ID must start with to be regarded as Assembly
- `GetAlongTime` - maximum time allowed to leave a classroom or the playground after the bell rings
- `LessonLength` - the length of a lesson period in frames (see `GameFps`)
- `LessonStartTime` - when a lesson starts (i.e. teacher will tell kids to sit down) in frames (see `GameFps`) from the start of the period
- `PlaytimePrefix` - what a lesson ID must start with to be regarded as Playtime
- `SpecialPlaytimeProbability` - the probability that a playtime in the main timetable will be replaced by a special playtime

## [TimingConfig]

The `TimingConfig` section contains configuration parameters in the format:

    parameterName, parameterValue

Recognised parameters are:

- `BendOverDelay` - the delay (in frames) before Eric stands upright after bending over (as when releasing mice)
- `DethronedDelay` - the delay before a character rises after being pushed out of a seat
- `EricWalkDelay` - the number of frames between successive movements of Eric when he’s walking
- `JumpDelay` - the delay (in frames) before Eric returns to the floor after jumping
- `KnockedOverDelay` - the delay before a knocked over teacher rises
- `KnockoutDelay` - the delay before a knocked out kid rises
- `GoFast` - the number of frames between successive movements of a character who is moving quickly; this parameter is used when a character is running or speaking
- `GoFaster` - the number of frames between successive movements of a character who is moving even quicker; this parameter is used when a character is throwing a punch or firing a catapult
- `GoSlow` - the number of frames between consecutive movements of a character who is moving slowly; this parameter is used when a character is walking at a normal pace
- `ReprimandDelay` - the delay before a knocked over teacher gives lines to someone for knocking him over
- `SpeedChangeDelayRange` - the minimum and maximum values of the delay between a character’s walking speed changes (used by kids, who walk half the time and run the other half)
- `TellEricDelay` - the length of time a character will wait for Eric to respond to a message before repeating it

## [Walls]

The `Walls` section contains details of the impenetrable barriers in the skool. Each line has the form:

    wallId, x, bottomY, topY

where:

- `wallId` is the wall’s unique ID
- `x` is the wall’s x-coordinate
- `bottomY` and `topY` are the y-coordinates of the bottom and top of the wall

For example:

    FarLeftWall, 0, 20, 0

defines the wall at the far left (x=0) of the skool, which stretches from the bottom floor (y=20) to the ceiling of the top floor (y=0).

## [Water]

Each line in the `Water` section has the form:

    characterId, waterId, spriteGroupId, commandListId, animationPhases

where:

- `characterId` is the unique ID of the character to give water pistol-firing ability to
- `waterId` is the unique ID for the water sprite
- `spriteGroupId` is the ID of the sprite group to use for the water fired from the pistol
- `commandListId` is the unique ID of the command list that the water will use when fired from the pistol
- `animationPhases` is the ID of the sequence of animation phases that the water will use after being fired from the water pistol

Each character whose unique ID appears in this section will be given the ability to fire a water pistol. In the stock Pyskool this will be Eric alone; he is the only character with a water pistol-firing sprite.

## [WaterDrop]

The `WaterDrop` section defines a drop of water (as knocked out of a cup by a catapult pellet). It contains a single line of the form:

    objectId, spriteGroupId, commandListId, hitXY

where:

- `objectId` is a unique ID for the drop of water
- `spriteGroupId` is the ID of the sprite group to use for the drop of water
- `commandListId` is the unique ID of the command list that the drop of water will use when knocked out of a cup
- `hitXY` is the coordinates of the water drop within its sprite (used for collision detection)

## [Windows]

The `Windows` section contains details of the windows in the game. Each line has the form:

    windowId, x, bottomY, topY, initiallyShut, openerCoords, shutTopLeft, size, coords, descentPhases[, notABird]

where:

- `windowId` is the window’s unique ID
- `x` is the window’s x-coordinate
- `bottomY` and `topY` are the y-coordinates of the bottom and top of the window
- `initiallyShut` is `Y` if the window should be shut when the game starts
- `openerCoords` are the coordinates (in (x, y) form) at which a character should stand in order to open the window
- `shutTopLeft` is the coordinates (in (x, y) form) of the top left of the image of the window when shut
- `size` is the size of the image (in (width, height) form)
- `coords` are the coordinates (in (x, y) form) of the window in the skool
- `descentPhases` is the ID of the sequence of animation phases to use for Eric if he jumps out of the window
- `notABird` is the ID of the command list Mr Wacker should switch to when Eric hits the ground after falling out of the window; if defined, Eric will be paralysed when he hits the ground

The window images can be found in mutables.png (or mutables_ink.png and mutables_paper.png if `GraphicsMode` is 1 - see [ScreenConfig]). mutables.png is arranged so that the image of a window when open is at (x + width, y), where (x, y) are the coordinates of the image of the same window when shut. The open/shut images for any given window are the same size.
