checkSpawnPlacements

@Internal
public static boolean checkSpawnPlacements(EntityType<?> entityType,
 ServerLevelAccessor level,
 MobSpawnType spawnType,
 BlockPos pos,
 RandomSource random,
 boolean defaultResult)

Internal, should only be called via 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).

See Also:

• MobSpawnEvent.SpawnPlacementCheck

checkSpawnPosition

public static boolean checkSpawnPosition(Mob mob,
 ServerLevelAccessor level,
 MobSpawnType spawnType)

Checks if the current position of the passed mob is valid for spawning, by firing MobSpawnEvent.PositionCheck.
The default check is to perform the logical and of Mob.checkSpawnRules(net.minecraft.world.level.LevelAccessor, net.minecraft.world.entity.MobSpawnType) and Mob.checkSpawnObstruction(net.minecraft.world.level.LevelReader).

Parameters:

mob - The mob being spawned.

level - The level the mob will be added to, if successful.

spawnType - The spawn type of the spawn.

Returns:

True, if the position is valid, as determined by the contract of MobSpawnEvent.PositionCheck.

See Also:

• MobSpawnEvent.PositionCheck

checkSpawnPositionSpawner

public static boolean checkSpawnPositionSpawner(Mob mob,
 ServerLevelAccessor level,
 MobSpawnType spawnType,
 SpawnData spawnData,
 BaseSpawner spawner)

Specialized variant of checkSpawnPosition(net.minecraft.world.entity.Mob, net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.entity.MobSpawnType) for spawners, as they have slightly different checks.

See Also:

• #CheckSpawnPosition

Implementation Note:

See in-line comments about custom spawn rules.

onFinalizeSpawn

@Nullable
public static @Nullable SpawnGroupData onFinalizeSpawn(Mob mob,
 ServerLevelAccessor level,
 DifficultyInstance difficulty,
 MobSpawnType spawnType,
 @Nullable
 @Nullable SpawnGroupData spawnData,
 @Nullable
 @Nullable CompoundTag spawnTag)

Vanilla calls to Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.MobSpawnType, net.minecraft.world.entity.SpawnGroupData, net.minecraft.nbt.CompoundTag) are replaced with calls to this method via coremod.
Mods should call this method in place of calling Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.MobSpawnType, net.minecraft.world.entity.SpawnGroupData, net.minecraft.nbt.CompoundTag). Super calls (from within overrides) should not be wrapped.

When interfacing with this event, write all code as normal, and replace the call to Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.MobSpawnType, net.minecraft.world.entity.SpawnGroupData, net.minecraft.nbt.CompoundTag) with a call to this method.

As an example, the following code block:

 var zombie = new Zombie(level);
 zombie.finalizeSpawn(level, difficulty, spawnType, spawnData, spawnTag);
 level.tryAddFreshEntityWithPassengers(zombie);
 if (zombie.isAddedToWorld()) {
     // Do stuff with your new zombie
 }
 

Would become:

 var zombie = new Zombie(level);
 EventHook.onFinalizeSpawn(zombie, level, difficulty, spawnType, spawnData, spawnTag);
 level.tryAddFreshEntityWithPassengers(zombie);
 if (zombie.isAddedToWorld()) {
     // Do stuff with your new zombie
 }
 

The only code that changes is the Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.MobSpawnType, net.minecraft.world.entity.SpawnGroupData, net.minecraft.nbt.CompoundTag) call.

Returns:

The SpawnGroupData from this event, or null if it was canceled. The return value of this method has no bearing on if the entity will be spawned.

See Also:

• MobSpawnEvent.FinalizeSpawn
• Mob.finalizeSpawn(ServerLevelAccessor, DifficultyInstance, MobSpawnType, SpawnGroupData, CompoundTag)

API Note:

Callers do not need to check if the entity's spawn was cancelled, as the spawn will be blocked by Forge.

Implementation Note:

Changes to the signature of this method must be reflected in the method redirector coremod.

@Nullable
public static MobSpawnEvent.FinalizeSpawn onFinalizeSpawnSpawner(Mob mob,
 ServerLevelAccessor level,

Returns the FinalizeSpawn event instance, or null if it was canceled.
This is separate since mob spawners perform special finalizeSpawn handling when NBT data is present, but we still want to fire the event.
This overload is also the only way to pass through a BaseSpawner instance.
