GMS 2.3+ Cellular Automata Algorithm

This asset is a fast implementation of a Procedural Cellular Automata Cave Generation algorithm for GameMakerStudio 2.3+, written purely in GML.

You can choose between two versions of this algorithm. The "readable" variant and the optimized one.

The optimized version generates huge caves in the matter of a few hundred milliseconds: I was able to generate a cave consisting of more than 220,000 tiles in less than 300ms  (when using the YYC)!

Note: Since a room's size can't be changed whilst a room is the current room,  you'll find a global variable at the bottom of the "Cave" script that stores a "Cave" struct. The struct will be created before the first room is started, allowing me to change its size. You can customize the cave using this struct.
