CARuins is a world generation mod that creates ruins from cellular automata, hence the name (CARuins = Cellular Automata Ruins).
CARuins can take the form of towers, bizarre statues, pyramids, mysterious elevated temples, or huge multifloor underground dungeons. They can stretch deep underground and are populated with hidden chambers and loot. Since they are generated from random seeds, there is a near-infinite variety of form, and no two CARuins you encounter will be alike. The 2D cellular automata used (including the famous Game of Life) have been selected from among the thousands possible in order to produce interesting structures.
Traps and SpawnersEditMany ruins have hidden traps like stone pressure plates connected to TNT blocks and dispensers rigged to fire several splash damage potions. The dispensers usually have around 30 splash damage potions in their inventory. Some ruins also have a central room with one mob spawner that can used to construct an exp orb generator or a mob grinder. Any type of mob spawner can and will be used. It is not unusual to see a creeper spawner, so watch out.
Several aspects of the CARuins mod can be configured manually with the "CARuinsSettings.txt" config file. If you are using the Technic launcher on a Windows Vista, Windows 7 OS, or Windows 8 you will probably find this file in the folder "C:\Users\YOURUSERNAME\AppData\Roaming\.techniclauncher\technicssp\", and on Mac OSX, you will need to go to YOURUSERNAME, hold alt, click on go at the top of the screen, Library>Application Support>techniclauncher>technicssp>. Most of the settings are pretty much self-explanatory, and the file is also well commented.
The standard config file should look like this:
