Mob Spawner types

Hi,

I am new to spawners and was wondering how do you set a spawner to a specific entity when it is placed?

It's in the CreatureSpawner class.

PHP:

//block place
Block b = event.getBlock();
if(b.getType.equals(Material.MOB_SPAWNER){
CreatureSpawner cs = (CreatureSpawner) b;

cs.setSpawnedType(EntityType.ZOMBIE)
}

 

Hey thanks xTrollxDudex

If you want to set it before its placed I think you can use

Code:

item.setDurability()

 

I am getting a weird error when I place the spawner here is my code and the stack trace

Code:java

 
public class Event implements Listener
{
 
@EventHandler(priority = EventPriority.NORMAL)
public void onBlockPlace(BlockPlaceEvent e)
{
Player p = e.getPlayer();
 
if (p.getItemInHand() != null) 
{
if(itemCheck(p, "Creeper Cage")==true)
{
Block creeperspawner = e.getBlock();
if(creeperspawner.getType().equals(Material.MOB_SPAWNER))
{
CreatureSpawner cs = (CreatureSpawner) creeperspawner;
 
cs.setSpawnedType(EntityType.CREEPER);
cs.update();
}
 
}
 
 
else if(itemCheck(p, "Skeleton Cage")==true)
{
p.sendMessage("skelton cage");
}
 
else if(itemCheck(p, "Spider Cage")==true)
{
 
}
}
} 
 
 
public boolean itemCheck(Player player, String name)
{
 
boolean returnValue = false;
 
    ItemStack i = player.getItemInHand();
    if(i == null)return false; // Fail the test if there is no item in hand
    if(!i.hasItemMeta())return false; // Fail the test if item does not have metadata
    ItemMeta im = i.getItemMeta();
    if(!im.hasDisplayName())return false; // Fail the test if the item doesn't have a display name
    String dn = im.getDisplayName();
    List<String> lore = im.getLore();
    if(lore != null)
    {
   if(dn.indexOf(name) > -1)
   {
   returnValue = true;
   }
    }
 
    return returnValue;
}
 
}

You have to use

for the BlockState

 

I also think that

Code:

cs.setSpawnedType(EntityType.CREEPER)

should be

Code:

cs.setSpawnedType(CreatureType.CREEPER)

 

Thanks foodyling and xxMOxMOxx , it shows the creeper inside the spawner but it won't spawn anything?

EDIT: Nevermind! I got it to work thanks guys
