lattely moorhead, zulu and ryan wilkie have complained that my redstone clocks created lag when they were active. I agreed, and decided that I would make a redstone clock that didn't create lag.
I have come up with a solution: Mob clock.
It's simply a box that has water running in circles with a pressure pad at one point. As the animal floats through, it activates the pad. It's pretty regular, even if it could be better.
I'll keep you guys updated.
