1/2 Ray Caster made in Processing

I forgot to show this in the video but the grid can be changed and the walls for the raycasting will be created effectively for all of them.

I had put it into mine to make it work and made the walls dynamically change to grid that you can change by changing the data in the grid array.

I have made a raycaster in cpp with sfml but it was not based on grid and had a hard time getting the ray line segment intersection formula to work
