Module reference

Everything Purr hands you. Each module is a flat namespace of functions, always in scope, with no classes to instantiate and no objects to wire up.

The game loop

A Purr program is a tigr script. Define up to three top-level functions and Purr calls them for you: init once at startup, then update and draw every frame. Every module is already in scope, so there's nothing to import.

main.tg


init := fn() {
    // called once at startup: bind actions, set up state
    Input.bind('jump', 'space');
};

update := fn(dt) {
    // called every fixed step: read input, move things
    if Input.pressed('jump') { /* ... */ };
};

draw := fn() {
    // called every frame: paint the world
    Gfx.clear(43, 34, 28);
};

no functions match that filter 🐾
