When i try to call ItemStack#shrink it doesn't actually shrink anything. For example inside my ItemPickupEvent

@SubscribeEvent
	public void pickUpItems(ItemPickupEvent event) {
		if (!event.player.world.isRemote) {
			EntityPlayer player = event.player;
			for (int i = 0; i < player.inventory.getSizeInventory(); i++) {
				ItemStack stack = player.inventory.getStackInSlot(i);
				if (stack.getItem() instanceof ItemContract && stack.hasTagCompound() && stack.getTagCompound().hasKey("contract") && stack.getTagCompound().hasKey("boundId") && stack.getTagCompound().hasKey("items") && !((ItemContract) stack.getItem()).complete(stack)) {
					if (Util.findPlayer(stack.getTagCompound().getString("boundId")) == player) {
						NBTTagList list = stack.getTagCompound().getTagList("items", Constants.NBT.TAG_COMPOUND);
						for (int t = 0; t < list.tagCount(); t++) {
							NBTTagCompound tag = list.getCompoundTagAt(t);
							if (event.getStack().getItem() == ForgeRegistries.ITEMS.getValue(new ResourceLocation(tag.getString("item")))) {
								int complete = tag.getInteger("amountComplete");
								int gained = event.getStack().getCount();
								int toShrink = Math.min(tag.getInteger("amountTotal") - complete, gained);
								event.getStack().shrink(toShrink);
								tag.setInteger("amountComplete", complete + toShrink);
								break;
							}
						}
					}
				}
			}
		}
	}

debugger says its shrinked, but the player still gets the full thing anyways.

 

Same problem, I want item to goaway after right click, so i do 

player.getHeldItem(hand).shrink(1);

but it still just stays in the inv.

 

Thanks!

I might be wrong, but mustn't shrink(int) be called on both the server and client?

 

I think your client is not updating the values, but it has actually happened server-side. Looks like you may have to use a packet to notify the client.

@MSpace-Dev I dunno, it was called without the world.isRemote check and it still doesn't shrink

Do you have the project on Github for further inspection?

@MSpace-Dev Hey, it turns out ItemPickupEvent is deprecated, use EntityItemPickUp instead, but check us out on github if u want
