Hey, I'm attempting to make an item take damage over time. I plan to have the item last 20 active minutes, so 20 x 60 x 20 ticks = 24000.

 

Anyways, the issue is I can't get the item to take damage.

 

package noahc3.AbilityStones;

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



public class ItemRegenerationStone extends Item
{

//use timer in ticks (24000)
public static final int USE_TIMER = 24000;
public ItemRegenerationStone() {
	setMaxStackSize(1);
	setMaxDamage(USE_TIMER);
	setNoRepair();
}


@Override
public void onUpdate(ItemStack itemstack, World world, Entity entity, int i, boolean flag)
{
	//stuff to do when active
	((EntityLivingBase) entity).addPotionEffect(new PotionEffect(Potion.regeneration.id, 20, 1));
}

}

 

So I wan't it to lose 1 durability per tick. (so 20/second, hence the really high max damage), what I need to know is what do I use to make it gain a damage? I've seen both attemptDamageItem() and damageItem(), but I'm not sure which one to use and how to use it.

 

Any help would be appreciated!

Well, you should use one of those and pass a type of damage and the entity repainted (the player, null with throw errors).

Or override getDamage and store the timer in nbt.

I figured out how to do it, but yea, I decided to move the timer to NBT to stop the weird jumpy stuff it does when you hold it in your hand.

 

Thanks anyways.
