Techno573

could you send to me the code line that does this? i'm quite new to java and i'm still learning... I forgot that there. Thanks for pointing me this. I'll remove it... Edit: I was looking at the PlagueDoctor class and i've noticed a warning on the line that says: corpseEntity.copyLocationAndAnglesFrom(victimEntity); it says that it could cause a NullPointerException.

I'm trying to make a mod, but i keep getting an error when i get killed by an entity...
