My friend and I made a bunch of mob grinders (Correctly) but when we put the zombie spawners in the zombies did not swim up the water stream, we asked Helpers "Waterfall26 and ExpandingMC" but they did not seem to know the problem and directed me here... We've built the grinders correctly as I've built them more than once before but it seems zombies don't swim up water on this particular server. I'm not sure if it's a bug or intended. Thanks RIP One day of my life :3
Mobs GUI is disabled when they are spawned unnaturally (Aka spawners). so these mobs will not swim up unless forcefully push or pulled up. I would suggest rather using a upward water flow stair case or to re-design your spawner. maybe a timed crusher, maybe just pushed and fall. there are 100's of designs out there. maybe make your own
Thanks for the reply. By an "upward water flow staircase" do you mean something like how an MCMMO Acrobatics Grinder works? Nonetheless will test this out in SP to find the most effective design then implement it onto the server. Thanks again for your reply -Cotton
