Line Of Sight or Shadow Casting in 2D

In this (long, sorry) video I cover a variety of things to implement a classing line-of-sight mapping, or shadow casting depending on your perspective. It's also the first olc::PixelGameEngine project I've done a video for, so I spend some time showing you how to set up Visual Studio to use this engine. I'm quite pleased with the end result of these algorithms and I expect to use them quite a bit in more ambitious tile-based projects in the future.

These resources are excellent regarding the things seen in the video:
