I'm sorry if I sounded rude, it wasn't my intention. I was just trying to say that maybe sometimes it's better to test things yourself instead of copy and paste some code found online. For instance, try to look at the decompiled nms classes and understand how things works. At the beginning it can be a bit tricky but after you figure it out I can assure you that you will be pleased. At least, that's my experience concering nms. BTW, I'm not accusing you, just giving you some piece of advice <3 PS: I'm going to test the pathfinders on the slime. I'll let you know if it works for me.
