Hi, I'm trying to set a maximum spawn limit to an entity, here's my code but I can't seem to get it to work. The event handler is registered in the main mod class.

 

	@SubscribeEvent
public void maxNessieSpawn(LivingPackSizeEvent event){
	if(event.entityLiving instanceof EntityNessie){
		event.maxPackSize = 1;
		event.setResult(Result.ALLOW);
	}
}

That seems correct. Are you sure the event is firing? You should either trace execution in debug mode of Eclipse, or you should add a console or logger print statement to say something when the code is executed. If it doesn't execute, then it means you registered the event handler wrong.

 

However, is EntityNessie your own class? If it is, then you don't need an event to control this. Instead in the EntityNessie class you should @Override the getMaxSpawnedInChunk() method to return 1.

Thanks for the reply. I've checked in debug mode and the code is firing. It seems this sets a limit to spawn per chunk, while I'm looking for a limit for the entire world, like there being only one persistent EnderDragon

LivingSpawnEvent.CheckSpawn or if it is your own entity override getCanSpawnHere in the Entity class.

 

LivingSpawnEvent.CheckSpawn was exactly what I needed! Thank you!
