Can someone tell me why this code crashes? Thanks!

First, give us your Minecraft and Forge version.

 

Second, give the debug.log and at least a brief description of the crash.

 

Third, you're passing in a `null` to the `EndermanEntity` constructor. That's probably what's causing the crash, but provide more details.

 

Fourth, your whole spawning code from the EndermanEntity constructor up to the world.addEntity should be surrounded by the !isRemote check.

I assume you are using 1.14+ (there's only one arg in 1.12), you need to pass 

EntityType.ENDERMAN

into the first arg instead of null.

Also like sciwhiz12 said you need to provide more information.

This was the problem. Thanks a lot.
