[1.16.1] Help with an Event


Recommended Posts

Hello! Novice modder here. I am creating an item that spawns a creeper at the player's location upon player death. It works fine, however I am trying to make it so that the KPS ItemStack is shrank (shrunk?) by 1 each time the player dies, as if the items are being "consumed" by spawning a creeper. How would I go about doing this?

Here is my current code:

public class KPSEvent {
    public void onDie(LivingDeathEvent e) {
        LivingEntity k = e.getEntityLiving();
        ItemStack sl = new ItemStack(Holder.KPS);
        CreeperEntity c = new CreeperEntity(EntityType.CREEPER, k.getEntityWorld());
        if(e.getEntity() instanceof PlayerEntity) {
            if(((PlayerEntity) e.getEntity()).inventory.hasItemStack(sl)) {
                ((PlayerEntity) e.getEntity()).inventory.deleteStack(sl);
                c.setPosition(k.getPosX(), k.getPosY()+1, k.getPosZ());

I'm quite positive the `ItemStack.shrink(1)` method is what you're looking for.

So you will probably want to retrieve an ItemStack that exists in the player's inventory, and call shrink on it.

Have you ever want the new operator to return a type that you didn't ask for? Well, now you can!
