[1.16.1] Help with an Event

[Giga_5]

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 {
    @SubscribeEvent
    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());
                k.getEntityWorld().addEntity(c);
            }
        }
    }
}

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

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