Entity Pickup Item event?

Hi guys,

I want to stop mobs picking up certain items. How can I detect when a mob picks an item up?

Thanks.

 

If you're talking about Endermen picking up blocks, you can use EntityChangeBlockEvent.

Code:

@EventHandler
public void onEntityChangeBlock(EntityChangeBlockEvent e) {
    Entity entity = e.getEntity();
    Block from    = e.getBlock();
    Material to    = e.getTo();
 
    if(entity instanceof Enderman) {
        // I think you know where to go from here ;)
    }
}

 

Or are talking about Zombies picking up swords etc?

I'm pretty sure that's what he meant. netherfoam if so, Bukkit hasn't added support for that yet, and if you want to stop it, you might have to try out some NBT stuff.

 

Yeah, I had a look at the NBT tags, there is one for allowPickup or something. Unfortunately, I only want a certain set of items not to be picked up :/ And mobs disregard ItemPickupDelay too... https://bukkit.atlassian.net/browse/BUKKIT-3132

I'll be waiting eagerly on this api :/

 

API had nothing useful in it (A few builds ago it was added).

How can I set an item entity to have 0 items? Would I have to use NMS?

Found it.

Code:java

 
//Fetch the NMS item
net.minecraft.server.v1_4_5.ItemStack nmsI = CraftItemStack.createNMSItemStack(iStack);
//Force the count to 0, don't notify anything though.
nmsI.count = 0;
//Get the itemstack back as a bukkit stack
iStack = CraftItemStack.asBukkitStack(nmsI);
//Set the display item to the stack.
this.item.setItemStack(iStack);

How would you implement this into the code? I am not sure where to put this, i just want to cancel all item pickups for entitys, players should still be able to pick items up.
