Class StructureSpawnListGatherEvent

java.lang.Object
net.minecraftforge.eventbus.api.Event
net.minecraftforge.event.world.StructureSpawnListGatherEvent
public class StructureSpawnListGatherEvent extends net.minecraftforge.eventbus.api.Event
This event fires when a Structure is gathering what mobs/creatures can spawn in it. In order to maintain the most compatibility possible with other mods' modifications to a structure, the event should be assigned a EventPriority as follows: - Additions : EventPriority.HIGH - Removals : EventPriority.NORMAL - Any other modification : EventPriority.LOW Be aware that another mod could have done an operation beforehand, so an expected value out of a vanilla structure might not always be the same, depending on other mods.
