Scripting

Warning: incorrect scripts usage might break everything. Use with caution and always test your scripts!

To make use of scripting system you need to create script file in "Data/Scripts". It's a simple text file with ".script" extension (if you don't have extensions enabled in explorer, then you should do it right now. If you're not willing to, you'll have to find an example script file somewhere and edit it). Script file name can be:

• MapName.script - where "MapName" is... well, name of the map you want to bind this script to.
• DecorationName.script - where "DecorationName" is name of decoration you want to bind this script to. This script will be used when player is near decoration and presses use.
• Any other script will be loaded only if it was set in triggers or terminals settings (see "Triggers")

The scripting language is very simple to use:

Commands are written each on its own line. Any argument these commands need should be separated by a single whitespace. That's it, commands are executed in order top to bottom of the file.

Example:

image Character Sprites/Characters/Character.png

show Character 0 0 2

text "Hello World!"

hide Character 2

timeout 2

map start

This script will load image, set it's name as Character, show it at 0, 0 within 2 seconds, show text on screen, hide image within 2 seconds, set timeout for 2 seconds start the map.

Variables

A variable is a name that you can bind a certain value to. There are three kinds of variables:

• Global - available entire game disregarding of map player currently plays.
• Map variables - available during current map. Deleted after it's over.
• Local variables - available only during current script. Deleted after it's done working.

To set a variable you just need to write it's name and a value, separated by "=". "global." prefix is for global variables, "map." is for map variables:

global.value=10

map.value="Character"

value=10

To use a variable you need to put $ symbol before it's name:

text "$global.value"

image $map.value Sprites/Characters/Character.png

text "$value"

If you need to calculate something (and variable is a number) use next operators:

value+=2 //Addition

value-=2 //Subtraction

value*=2 //Multiplication

value/=2 //Subdivision

value++ //Increment (increase by 1)

value-- //Decrement (decrease by 1)

Be aware that beginning of one variable's name can't contain the full name of the other variable. For example:

global.count=10 global.countnumber=5

It's a wrong way to name variables, because now you can't interact with "global.countnumber" variable - the game engine will always refer to the "global.count" variable first, ignoring the "-number" part on the end. We can easily fix it by changing the letter order:

global.count=10 global.numbercount=5

Conditions

Conditions are blocks of code that will be executed only if some conditions are met. Be aware: "if", and comparator are commands as well, so there MUST be whitespace separating them:

if $value == 1 {

map next

} else {

map goto 3

}

Code inside if block will be executed only if value is 1. Code inside "else" block will be executed if value is NOT 1. Else block may be imotted if you don't need it:

if $value == 1 {

map next

}

Instead of "==" you can use:

• != - condition is met if value is NOT equal
• <= - condition is met if value is less or equal
• >= - condition is met if value is greater or equal
• < - condition is met if value is less
• > - condition is met if value is greater

Procedures

Procedures are pieces of code that can be used whenever you want. Key word "end" marks procedure end, so be sure there is enough of these:

procedure helloworld

text "Hello World!"

end; //semicolon in necessary if you have more than one procedure

procedure helloworld2

text "Hello World 2!"

end

Calling a procedure is just a matter of using command "call":

call helloworld call helloworld2

Procedures exist only inside one single file. If you need them in another file, you'll have to copy them. You can also call procedures from inside other procedures or the very procedure itself. For example:

procedure loop

map.var++

if $map.var == 100 {

map return

} else {

call loop

}

end

This procedure will repeatedly call itself to increment variable "map.var" by one until it would be equal to 100. After that procedure stops the execution of the script.

All procedures must be in the beginning of the script. They wont work when placed after or in the middle of the script.

Commentaries

If you put "//" in front of a line this line will become a commentary - a non-executable code that is just here to set a note for yourself.

//This is a commentary call helloworld

Live Variables in HUD:

Live Variables on screen.

Addin a live variable in to the hud is quite straight forward

Open up the HUD config file and add the following two lines.

The first numeric value is the position on the screen left to right and the second one is vertical position

text 0.01 0.8 (variable name)

variable 0.075 0.8 (global.example)

Generic commands list:

Please note that rectangular braces are here just to mark an argument. You do not need to put them yourself.

auto

auto [0/1] - sets auto execution. By default script is executed line-by-line as player presses left mouse button or use button.

timeout

timeout time - sets timeout. Next script line will be executed automatically when timeout is over.

call

call procedureName - calls a procedure.

pause

pause - pauses script until mouse button is pressed or a use key is pressed.

halt

halt - stops script entirely.

keeptrigger

keeptrigger - prevents trigger that called the script from being deleted when the script ends.

Game commands list:

map

map start [keepmusic] - starts map after cutscene script is over. Must only be used in cutscenes at the start of a map! If keepmusic is 1 - music played in the cutscene will be played on map as well. If it's 0 or omitted, map music will be played.

map next - moves to the next map.

map return [KeepSounds? 0/1/2/3] - return to map. Use only in triggers, terminals or active decorations with scripts. KeepSounds: 0 stops all sounds, 1 keeps music, 2 keeps music and sfx , 3 keeps scripted sounds

map quickreturn [KeepSounds? 0/1/2/3] - return to map without interrupting player input, enabling keybind scripts to run repeatedly while held, and avoiding input delay when a trigger is activated

map goto [index] - moves to a certain map. index - map number in the list (starting from 0).

experimental ability to run a looping script in the background.

If you have a mapname_loop.script, it will run continuously in the background while you're on that map. For now, I don't recommend using this in any games you're about to release. It's more like a public beta test. This feature may be changed, or run at a fixed time interval in a future update.
