Hey,

 

	public boolean hitEntity(ItemStack par1ItemStack, EntityLivingBase par2EntityLivingBase, EntityLivingBase par3EntityLivingBase)
  {
    if (par3EntityLivingBase.isSneaking())
    {
      par3EntityLivingBase.dropItem(Waluta.instance, 1);
      par1ItemStack.damageItem(100, par3EntityLivingBase);
      return true;
    }
    par1ItemStack.damageItem(1, par3EntityLivingBase);
    return true;
}

 

How to make something similar like this but on pickaxe ? I was thinking about that if player is mining without holding shift diamond,iron,emerald,gold ore it drop normal items and subtract -1 durability, but when player will hold shift and than mine it will drop that (Waluta.instance, 1) item but it will also subtract -100 durability.

 

Sorry for my english.

Can you show me example ? with PlayerInteractEvent use?

	public boolean onBlockLeftClicked(ItemStack damage, EntityLivingBase player, PlayerInteractEvent event)
	{
	if (event.action != PlayerInteractEvent.Action.LEFT_CLICK_BLOCK){
	   if (player.isSneaking())
	   {
		   player.dropItem(Waluta.instance, 1);
		   damage.damageItem(100, player);
	      return true;
	   }
	}
	damage.damageItem(1, player);
	return true;
	}

 

Is that right or not?

You would know if you just looked at ANY tutorial on google... Search Forge Events.

 

You are missing @SubscribeEvent.

Event method takes only one argument - Event itself.

You pull data only from event. Exacly like you did with event.action...

If event is client side you can also use client classes, e.g Minecraft.class#thePlayer.

I had other idea and i made something like this :

 

	public boolean onBlockDestroyed(ItemStack damage, World world, Block block, int arg1, int arg2, int arg3, EntityLivingBase player)
	{
    if ((double)block.getBlockHardness(world, arg1, arg2, arg3) != 0.0D)
    {
    	if (player.isSneaking())
	    {
    	player.dropItem(Waluta.instance, 1);
    	damage.damageItem(100, player);
	    return true;
    	}
    }
    damage.damageItem(1, player);
    return true;
}

 

It works fine.
