if i wanted to make an item decay upon being held how would i do this?

i have already tried a few methods to no avail and i cant find any good/ uptodate tutorials for it.

i was wondeing if anyone could help me with this, i am assuming i will have to use the servertick somehow.

Use the onUpdate method in your item class, check if the ItemStack is the same as the one the Player's holding and then you do the needed stuff. If you're dealing that with damage, increase the ItemStack's damage until it's broken.

i found this but i doesnt seem to work and im not good enough to manipulate it, this currently as soon as its gotten dmg value goes straight to one the all the way up to its max the crashes the game, what i would like it to do it when held go down from the highest value until it breaks. if you could explain to me how to do this that would be great.

public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)
{
  if(stack.getItemDamage() == 1)
  {
   stack.itemID = 1;
  }else if(stack.getItemDamage() > 1 ){
   stack.setItemDamage(stack.getItemDamage() - 1);
  }else{
   stack.setItemDamage(20);
  }
  
}

you need to INCREASE the damage, not decrease it! If the damage reached it's max damage, it should decay.

ok so now the item loses health until its got 1 left then just stays in the inventory, ie doesnt break?

   public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)
    {
     if(stack.getItemDamage() == 1)
     {
      stack.itemID = 522;
     }else if(stack.getItemDamage() > 1 ){
      stack.setItemDamage(stack.getItemDamage() +1);
     }else{
      stack.setItemDamage(20);
     }
     
    }

anyone?

is it this part?

  }else{
      stack.setItemDamage(20);

thats all of it...

i do not no, i know it should take one damage from it per tick and when it reaches zero it should brake.

check if itemselected = Item.shard.shiftedindex

if true check health of item,

if health = 0 then destroy item

else -1 health of item.

 

closer

 

so something like

 

public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)

    {

if(player.getCurrentItemOrArmor(0) != null){

ItemStack hand = player.getCurrentItemOrArmor(0);

if(hand.getItem() == ashtonsmod.DarkShard){

 

if(stack.getItemDamage() < 1 ){

(What is the break an item code?)

else

stack.setItemDamage(stack.getItemDamage() +1);

 

(probably wrong i know but its my best effort )

 

public void onUpdate(ItemStack stack, World world, Entity entity, int par4, boolean par5)

    {

if(player.getCurrentItemOrArmor(0) != null){

        ItemStack hand = player.getCurrentItemOrArmor(0);

        if(hand.getItem() == ashtonsmod.DarkShard){

 

if(stack.getItemDamage() > 1 ){

(What is the break an item code?)

else

stack.setItemDamage(stack.getItemDamage() +1);

ok so can someone correct me or just tell me how because ^ doesnt work.
