MobSpawnEvent

public static class MobSpawnEvent.PositionCheck
extends MobSpawnEvent

This event is fired when a mob checks for a valid spawn position, after SpawnPlacements.checkSpawnRules(net.minecraft.world.entity.EntityType<T>, net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.entity.EntitySpawnReason, 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.EntitySpawnReason) 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.EntitySpawnReason) and Mob.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.

This event is fired on the main Forge event bus, only on the logical server.

API Note:

This event fires after Spawn Placement checks, which are the primary set of spawn checks.
