- Enclosing class:
- MobSpawnEvent
This event is fired when a mob checks for a valid spawn position, after
Conditions validated here include the following:
SpawnPlacements.checkSpawnRules(net.minecraft.world.entity.EntityType<T>, net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.entity.MobSpawnType, net.minecraft.core.BlockPos, net.minecraft.util.RandomSource) has been evaluated.Conditions validated here include the following:
- Obstruction - mobs inside blocks or fluids.
- Pathfinding - if the spawn block is valid for pathfinding.
- Sea Level - Ocelots check if the position is above sea level.
- Spawn Block - Ocelots check if the below block is grass or leaves.
These checks are performed by the vanilla methods Mob.checkSpawnRules(net.minecraft.world.level.LevelAccessor, net.minecraft.world.entity.MobSpawnType) and Mob.checkSpawnObstruction(net.minecraft.world.level.LevelReader).
The logical-and of both methods forms the default result of this event.
This event has a result.
To change the result of this event, use Event.setResult(net.minecraftforge.eventbus.api.Event.Result). Results are interpreted in the following manner:
- Allow - The position will be accepted, and the spawn process will continue.
- Default - The position will be accepted if
Mob.checkSpawnRules(net.minecraft.world.level.LevelAccessor, net.minecraft.world.entity.MobSpawnType)andMob.checkSpawnObstruction(net.minecraft.world.level.LevelReader)are both true. - Deny - The position will not be accepted. The spawn process will abort, and further events will not be called.
