I am struggling with a problem with LivingSpawnEvent.CheckSpawn. It works perfectly fine for hostile mobs but passive mobs that are generated at chunk generation time (i.e. passive sheep, cows and so on) are not going through that even it seems. Even though according to the Minecraft code it should. Here is the code snippet:

 

    @SubscribeEvent
    public void onEntitySpawnEvent(LivingSpawnEvent.CheckSpawn event) {
        System.out.println("event.entity.toString() = " + event.entity.toString());
    }

 

This code works fine for hostile mob spawns. I can see the print in my console but nothing happens for passive mobs.

 

Any clue?

Is there nobody who knows anything about this or can help me find a way to prevent passive mobs from spawning in freshly generated chunks? Thanks

this event is not fired for EntityAnimal or any derived class. try using EntityJoinWorld instead
