Raycasting Demo

A simple demo of a 2d lighting effect using ray casting to determine line of sight. The light emanates from the mouse location and is obstructed by the objects on the screen.

I created this while following along with the Comp4300 course streaming on YouTube.

Controls are listed on the screen while running but are as follows, along with more info.

They are partially obscured when the light is active.
Points are drawn with a gradient between full red  and white in order to visualize the order they are drawn.
