How would I stop sheep from spawning

[Cricket]

I am making a mod that completely revolves around sheep, I was looking for a way to make only my sheep spawn. Is there a certain event I should call or how would I go about doing this.

I use EntityJoinWorldEvent (it's a MinecraftForge event).

 

If I were you, I'd check if the "event.entity" that is spawned is an instance of EntitySheep.

I then would cancel the event to cancel the spawning of the sheep:  event.setCancelled(true);

 

If you want, you can use event.world (as the parameter in your custom Sheep class) and spawn it in the world in place of the vanilla sheep that spawned (event.entity.posX, event.entity.posY, event.entity.posZ
