[Help] How to do unsummon item npc

[darkpele]

I created a item that summon NPC, but when I use item the NPC spawn until the next restart.

I need the NPC would be deleted in specific time.

A friend told me that use this script in core for delete NPC, but i dont know where must put and i think is incomplete:

 

//  Por Creado Ashitaka e Implementado por Eggo
  static class DespawnTask implements Runnable
  {
          L2Spawn spawnedNPC = null;
          public DespawnTask(L2Spawn spawn)
          {
              spawnedNPC = spawn;
          }

          public void run()
          {
              try
              {
                  spawnedNPC.getLastSpawn().decayMe();
              } catch (Throwable t){}
          }
  }
  //

 

and this:

 

ThreadPoolManager.getInstance().scheduleGeneral(new DespawnTask(spawn), 600000);

 

Someone can help me?

Thanks
