[Mod] Game of Life [Experimental]
Posted: Mon Nov 02, 2015 23:11Hello all, as you've noticed, I've been working on a copy of Conway's Game of Life within Minetest.
However, due to how ABMs work, this code fails to work properly. It does, however, have configuration.
Secondly, there is no current way to start and stop ABMs from functioning due to Minetest's limited abilities.
To install this experimental mod, create a folder called gol, and a file called init.lua -- copy and paste the code into it, enable the mod via configure world - and it should run.
Dependancies:
Default, for textures.
