Welcome to the Obsi wiki!

This wiki is supposed to help a new developers of Obsi to figure out how does the game engine works without having to read the source code itself.

Here are all of the Obsi modules:

• obsi.audio - an audio module for obsi that includes most of the things you need to manually control the audio stuff.
• obsi.graphics - a 2D graphics module for drawing things on the screen, manipulating the screen offset and changing the palette.
• obsi.keyboard - keyboard module for checking what keys are down.
• obsi.mouse - mouse module for checking when the mouse was last time.
• obsi.time - module for checking the time since the game was launched.
• obsi.system - a module for quickly checking what host is running the game.
• obsi.state - a module for managing scenes and the state of the running game.

Some of the user-defined functions, all of them are called by obsi internally:

• obsi.load() - is called when the game is just launched.
• obsi.update(dt: number) - is called for a fixed time update (it can be ran multiple times before the obsi.draw).
• obsi.draw(dt: number) - is called for drawing things onto the screen.
• obsi.mousePressed(x: number, y: number, key: integer) - called when the user presses a mouse button.
• obsi.mouseReleased(x: number, y: number, key: integer) - called when the user lifts up a mouse button.
• obsi.keyPressed(key: integer) - called when the user presses a key.
• obsi.keyReleased(key: integer) - called when the user lifts up the key.
• obsi.windowFlush(window: Window) - called every frame before drawing the window on the terminal. Passes Window object as as first argument.
• obsi.resize(w: number, h: number) - called when recieved "term_resize" event.
• obsi.onEvent(eventData: table) - called on every event the game engine receives, except for the terminate event.
