This basics video tutorial shows you how a real time 2d lighting can be done in GameMaker Studio.

Basically what you see in this video is that you have one object that checks if there is a obsticle in the way in form of tiles. That is being stored in the buffer to create a primitve. This is in the end only tons of little triangles in a list that fill up the screen to indicate that the origin can't see there.

A disclaimer: This si quite demanding for your game, so only use it sparingly when you really need it. I have seen and tested a version that checked for wall objects instead of tiles, This one was even worse in performance.


The whole project is based on those 2 yoyo offical blog posts, so if you like to see the full documention, here are the links:
