This is a very simple implementation of mattdesl's Pixel Perfect 2D Shadows in Love2d/Lua. The code is simple and easy to understand. It is useful for applications that need bare-bone 2D raycasted lights and shadows. (No advanced features, such as normal maps, are provided.)
This was built and tested with Love 0.10.2.
addLight(x, y, size, r, g, b)
clearLights()
From your love.draw() function, you must call the provided function drawLights(drawOccludersFn, coordTransX, coordTransY). drawOccludersFn is a callback that draws all shadow-casting objects in the scene. (I recommend you store this in a variable, and then call it a second time from love.draw() to actually draw the objects.)
