      public static boolean checkSpawnPosition(net.minecraft.world.entity.Mob mob, net.minecraft.world.level.ServerLevelAccessor level, net.minecraft.world.entity.EntitySpawnReason 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.EntitySpawnReason) 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.

      Finalizes the spawn of a mob by firing the FinalizeSpawnEvent and calling Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData) with the result.

      Mods should call this method in place of calling Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData), unless calling super from within an override. Vanilla calls to Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData) are replaced with calls to this method via coremod, so calls to this method will not show in an IDE.

      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.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData) with a call to this method.

      As an example, the following code block: 

       var zombie = new Zombie(level);
 zombie.finalizeSpawn(level, difficulty, spawnType, spawnData);
 level.tryAddFreshEntityWithPassengers(zombie);
 if (zombie.isAddedToLevel()) {
     // Do stuff with your new zombie
 }
      Would become: 
       var zombie = new Zombie(level);
 EventHooks.finalizeMobSpawn(zombie, level, difficulty, spawnType, spawnData);
 level.tryAddFreshEntityWithPassengers(zombie);
 if (zombie.isAddedToLevel()) {
     // 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.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData) call.
      Parameters:
      mob - The mob whose spawn is being finalized
      level - The level the mob will be spawned in
      difficulty - The local difficulty at the position of the mob
      spawnType - The type of spawn that is occuring
      spawnData - Optional spawn data relevant to the mob being spawned
      Returns:
      The SpawnGroupData from the finalize, or null if it was canceled. The return value of this method has no bearing on if the entity will be spawned

      Finalizes the spawn of a mob by firing the FinalizeSpawnEvent and calling Mob.finalizeSpawn(net.minecraft.world.level.ServerLevelAccessor, net.minecraft.world.DifficultyInstance, net.minecraft.world.entity.EntitySpawnReason, net.minecraft.world.entity.SpawnGroupData) with the result.

      This method 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 an IOwnedSpawner instance.

      Parameters:
      mob - The mob whose spawn is being finalized
      level - The level the mob will be spawned in
      difficulty - The local difficulty at the position of the mob
      spawnType - The type of spawn that is occuring
      spawnData - Optional spawn data relevant to the mob being spawned
      spawner - The spawner that is attempting to spawn the mob
      def - If the spawner would normally call finalizeSpawn, regardless of the event
