Have you ever wanted to make something like a grid based RPG? Maybe a grid based roguelike? Well this demo has you covered. In this demo, there is a super easy to understand method of grid based movement called collision maps. It's fast, and easy to understand.
The whole system is tile based reducing CPU even further, and everything is done through a few lines of code to setup, and even less to use. In fact, all you need to do once it's setup is call checkCollision(x, y) to see if a position is free.
This asset does not handle RPG elements and such, this is strictly for movement and collisions.
