I'm quite sure there's simple ways to select which mob I want and teleport it into my torture chamber (big project at the moment, still at planning it) but for some reasons, my mind plays tricks on me right now, I swear there must be some mods that can do that somehow but I can't find any viable solution to pick up 1 mob from a cursed earth mob spawner and drop it into a spot with different torture devices, lets say I want Creepers to get into a Obsidian chamber with some TNT to kill them, skeletons to finish in a room with loads of arrow dispensers to show them who's the boss, and some villagers will eventually meet some zombies, I'M quite sure there's tons of stuff we can learn from this, I want to watch and experiment with them, curing them and see if their trades are better after a few dezombification process) now I just need to figure out how to choose and send the mobs to their respective destinations, I have pretty much all the mods in DW20 1.7.10 pack except funky locomotion, IC2, Buildcraft and Pneumaticraft.
