[1.11] Make item lose durability every 100 ticks


Frost2779

Recommended Posts

So I have an item that I want to make lost a durability every 5 seconds, so every 100 ticks. I've done some looking around about implementing a tick counter into NBT to help track this, but so far I have been unsuccessful in getting this to work(as entire functions that are present in the tutorial are not there any more).

Define "doesn't work."

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

 

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

 

DO NOT PM ME WITH PROBLEMS. No help will be given.

I tried that, and adding a counter, but it refuses to work.

I done that once before and it act perfect:

    @Override
    public boolean shouldCauseReequipAnimation(ItemStack oldStack, ItemStack newStack, boolean slotChanged)
    {
        return false;
    }

    @Override
    public void onUpdate(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected)
    {
        if(entityIn instanceof EntityLivingBase)
        {
            if(!stack.hasTagCompound())
            {
                stack.setTagCompound(new NBTTagCompound());
            }
            
            if (stack.getTagCompound().hasKey("TickCounter"))
            {
                int tickCounter = stack.getTagCompound().getInteger("TickCounter");
                if (tickCounter <= 0)
                {
                    stack.damageItem(1, ((EntityLivingBase) entityIn));
                    stack.getTagCompound().setInteger("TickCounter", 100);
                }
                else
                {
                    stack.getTagCompound().setInteger("TickCounter", --tickCounter);
                }
            }
            else
            {
                stack.getTagCompound().setInteger("TickCounter", 100);
            }
        }
    }

Crash is useless without your Item class.

My mistake

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.world.World;

public class ItemFullWill extends Item {

    public ItemFullWill(){
        this.setMaxDamage(100);
        this.setMaxStackSize(1);

    }

    @Override
    public boolean shouldCauseReequipAnimation(ItemStack oldStack, ItemStack newStack, boolean slotChanged) {
        return false;
    }

    @Override
    public void onUpdate(ItemStack stack, World worldIn, Entity entityIn, int itemSlot, boolean isSelected) {

        if(entityIn instanceof EntityLivingBase)
        {
            if (stack.hasTagCompound() && stack.getTagCompound().hasKey("TickCounter"))
            {
                int tickCounter = stack.getTagCompound().getInteger("TickCounter");
                if (tickCounter <= 0)
                {
                    stack.damageItem(1, ((EntityLivingBase) entityIn));
                    stack.getTagCompound().setInteger("TickCounter", 100);
                }
                else
                {
                    stack.getTagCompound().setInteger("TickCounter", --tickCounter);
                }
            }
            else
            {
                stack.getTagCompound().setInteger("TickCounter", 100);
            }
        }
    }
}

    • The mobs are moving normally for a second, then freeze, then go back to normal, and this repeats. I describe this as mob lag, bc they stutter as if they were lagging. I don't have the best wifi, but that shouldn't matter since its 10mbps which is enough for a server. I have 8 gigs of ram for it, no optimizations have worked, if there is anything more you may need to help lmk, ill describe.
