I want to make a chest that once you drop items in it, it deletes it.

I know how to make a chest, but i want to prevent it to store the inventory and it should delete everything it gets.

One way to do this would be to create your own Slot implementation, overriding any methods which refer to an inventory so that they do nothing but return empty stacks where needed.

i have added this to the tileentity's update method:

for (int slot = 0; slot < this.getSizeInventory(); slot++) {
            ItemStack stack = getStackInSlot(slot);
            if (stack != null) {
                decrStackSize(slot, 1);
                
            }

It deletes really fast. Not that i bother personally, but does this has any negative effects ont he gameplay? maybe lagg or something? Should i make it slower?
