Solved CreatureSpawnEvent with Metadata

Hello,

I am having some trouble ! I need to make it to were I can allow ONLY certain mobs spawn within a WorldGuard region. I got the format setup and everything, but it doesn't want to work !

Here is my code:

Code:java

 
@EventHandler
public void spawnCreature(PlayerInteractEvent event){
Player player = event.getPlayer();
 
if(event.getAction() == Action.RIGHT_CLICK_BLOCK){
if(player.getItemInHand().getType() == Material.DIAMOND_AXE){
if(event.getClickedBlock().getType() != Material.AIR){
Zombie customzombie = (Zombie)player.getWorld().spawnEntity(event.getClickedBlock().getLocation(), EntityType.ZOMBIE);
customzombie.setMetadata("zombie-spawn", new FixedMetadataValue(this.plugin, "true"));
customzombie.setCustomName("Fatty");
customzombie.setCustomNameVisible(true);
}
}
}
}
 
@EventHandler
public void onMobSpawn(CreatureSpawnEvent event){
if(event.getEntity() instanceof Zombie){
WorldGuardPlugin wg = (WorldGuardPlugin) Bukkit.getServer().getPluginManager().getPlugin("WorldGuard");
 ApplicableRegionSet set = wg.getRegionManager(event.getEntity().getWorld()).getApplicableRegions(event.getEntity().getLocation());
 for (ProtectedRegion region : set) {
 if(region.getId().equals("mobgame")){
 if(!event.getEntity().hasMetadata("zombie-spawn")){
 event.setCancelled(true);
 }
 }
}
}
}
 

Some people say this: "How can a creature spawn before it has metadata." Or "How can the event check if the creature has the Metadata before it is even spawned?"

In my code, first I set the creature spawn WITH the metadata value, then It checks for it. I don't think is it possible to check for a creature that spawns with Metadata. What I am trying to do is only spawn certain creatures within a WorldGuard region that I call. Mobs that I want to put in the worldguard region. I don't want natural spawns.

 

mrgreen33gamer schedule a 0 tick task (or use runTask) which checks the meta and removes if it is not there. It should work like the following:
- call to spawnEntity
- CreatureSpawnEvent is fired, task is scheduled
- spawnEntity returns, add meta
- task is ran (should even be the same tick). If the entity has meta it will not be removed.

SOLVED. So this is what I did. I checked the type of spawn, like Natural or Custom. I denied all that wasn't custom and spawned mobs in the arena, without telling the region: /region flag (name) mob-spawning deny
