API

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

global logo
global x = 10.0f

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

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

def update(dt) {
	x = x + 20.0f * dt
}

To run it, execute the following:

retroarch -L chailove_libretro.so main.chai

See the ChaiLove API for coverage of all the callbacks and methods in ChaiLove.
