[1.14.4] Give the player an item when durability reaches 0


Recommended Posts

Posted (edited)

Hi, I want to make an item with durability that will give you another item when the durability reaches 0, this item applies various effects when right clicked on a mob, but when his durability is 0 it never gives the player the item

 

Here is the code:

public class PepperSpray extends Item {
	public PepperSpray(Item.Properties properties) {
		super(properties.maxDamage(20));
	}

	   @Override
	   public boolean itemInteractionForEntity(ItemStack stack, PlayerEntity playerIn, LivingEntity target, net.minecraft.util.Hand hand) {
		   if (target.world.isRemote) return false;
	         if (target instanceof LivingEntity) {
	        	 target.addPotionEffect(new EffectInstance(Effects.POISON, 40));
	        	 target.addPotionEffect(new EffectInstance(Effects.BLINDNESS, 125));
	        	 target.addPotionEffect(new EffectInstance(Effects.WEAKNESS, 20));
	        	 stack.damageItem(1, target, e -> e.sendBreakAnimation(hand));
	        	 if (stack.isEmpty()) {
	                 stack = new ItemStack(Items.BEETROOT);
	              }
	         }

	        playerIn.getEntityWorld().playSound(null, playerIn.getPosition(), SoundEvents.ENTITY_CREEPER_HURT, SoundCategory.PLAYERS, 0.9f, 3.0f);
	        playerIn.swingArm(hand);
	 		playerIn.setActiveHand(hand);
	 		playerIn.addStat(Stats.ITEM_USED.get(this));
			return true;
	      }
	   
}

And here is the part that doesn't work.

if (stack.isEmpty()) {
	                 stack = new ItemStack(Items.BEETROOT);
	              }

Any help is appreciated.

Use player.addItemStackToInventory(...) instead of stack = new ItemStack. Also, why are you checking if target is an instance of LivingEntity? It is already defined as a LivingEntity. Did you mean to check if it is an instance of PlayerEntity?

Thanks, it worked! The only problem is that if you grab an item when durability reaches 0 (like if you have lots of items on the ground and you automatically pick up one), it won't give you the item because it doesn't detect it as an "empty" stack.

You need to handle that case yourself. addItemStackToInventory returns a value. Use that value to know whether or not you must spawn an EntityItem where the player is.

    • Version 1.19 - Forge 41.0.63 I want to create a wolf entity that I can ride, so far it seems to be working, but the problem is that when I get on the wolf, I can’t control it. I then discovered that the issue is that the server doesn’t detect that I’m riding the wolf, so I’m struggling with synchronization. However, it seems to not be working properly. As I understand it, the server receives the packet but doesn’t register it correctly. I’m a bit new to Java, and I’ll try to provide all the relevant code and prints *The comments and prints are translated by chatgpt since they were originally in Spanish* Thank you very much in advance No player is mounted, or the passenger is not a player.
