API

The ChaiLove API is roughly inspired by the LÖVE API. The following main.chai is a simple Hello World example:

global logo

def load() {
	logo = graphics.newImage("logo.png")
}

def draw() {
    graphics.print("Hello World!", 400, 300)
    graphics.draw(logo, 100, 100)
}

def update(delta) {
	// Change something on the screen.
}

To run it, execute the following:

retroarch -L chailove_libretro.so main.chai
