Well I know how to make blocks, items, guis and mobs and I understand basic java but I'm just trying to figure out how to do custom ais and custom potion effects and stuff. Idk, I I've looked at the squid class and all it is is a bunch of stuff about how to make the tentacles move. I extended EntityWaterMob but it still does that jumping thing. And I don't know how to make the custom ai, it just doesn't make much sense to me
