So I have the a flight ring, and I want it to consume an item, but I don't know much about NBT or what the equivalent to player.inventory.consumeInventoryItem(itemNameHere) is.

 

Here is my code so far, with nothing to consume or check for the item:

 

public class FlightDongle extends Item implements IFlight {

public FlightDongle(String unlocalizedName) 
{
	this.setUnlocalizedName(unlocalizedName);
	this.setCreativeTab(BamsMod.tabBams);
	this.setMaxStackSize(1);
}

@Override
public String getUnlocalizedName(ItemStack itemStack) 
{
	if (itemStack.getItemDamage() == 0) 
	{
		return this.getUnlocalizedName() + ".deactivated";
	}
	if (itemStack.getItemDamage() == 1) 
	{
		return this.getUnlocalizedName() + ".activated";
	}
	return "deactivated";
}

@Override
    public void addInformation(ItemStack itemStack, EntityPlayer player, List list, boolean bool)
    {
    	list.add("\u00A7f" + "Hold Shift For Details");
    	if((Keyboard.isKeyDown(42)) || (Keyboard.isKeyDown(54)))
    	{
    		list.add("");
    		list.add("\u00A7e" + "Consumes 1 BamSalt Every 2 Minutes.");
    	}
    }

@Override
public void getSubItems(Item item, CreativeTabs tabs, List subItems) 
{
	subItems.add(new ItemStack(item, 1, 0));
	subItems.add(new ItemStack(item, 1, 1));
}

@Override
public boolean onDroppedByPlayer(ItemStack stack, EntityPlayer player) 
{
	deactivateDongle(stack, player);
	return super.onDroppedByPlayer(stack, player);
}

@Override
public ActionResult<ItemStack> onItemRightClick(ItemStack itemStack, World world, EntityPlayer player, EnumHand hand) 
{
	if (itemStack.getItemDamage() == 0) 
	{
		activateDongle(itemStack, player);
	}
	else
	{
		deactivateDongle(itemStack, player);
	}
	return new ActionResult(EnumActionResult.PASS, itemStack);
}
@Override
public void activateDongle(ItemStack itemStack, EntityPlayer player) 
{
	itemStack.setItemDamage(1);
	player.capabilities.allowFlying = true;
	player.capabilities.isFlying = true;
	player.fallDistance = 0;

	player.sendPlayerAbilities();
}

@Override
public void deactivateDongle(ItemStack itemStack, EntityPlayer player) 
{
	itemStack.setItemDamage(0);
	player.capabilities.allowFlying = false;
	player.capabilities.isFlying = false;

	player.sendPlayerAbilities();
}

@Override
public boolean isActive(ItemStack itemStack) 
{
	return itemStack.getItemDamage()==1;
}

 

 

Well...a couple things (all unrelated to your problem) first.

• Why don't you set the unlocalized name to the registry name?
  
• Why do you use "\u00A7f" instead of the EnumChatFormat (EnumTextFormat? I forget the current class name)
  
• Why do you use Keyboard.isKeyDown(42)? I'm pretty sure the last bool parameter will do what you want.
  

 

Now, on to your question:

You don't have an onUpdate method anywhere to even handle the deduction over time.

I know that. I said that's what I need help with, is in the onUpdate method, as I've done this in 1.7, but didn't get it fully working. And I know, I've always done the meta data and the colors that way.

Well...step 1:

You need a way to count time.

Step 2:

When the time reaches a certain value, consume an item from the player's inventory (if it exists)

Step 3:

Reset the timer

Would I use some sort of tick handler to count the ticks? Also, I don't know what the equivalent of player.inventory.consumeInventoryItem(itemHere); is in 1.10. I have the onUpdate method and I've casted Entity to EntityPlayer, but don't know what to do from there. As I said, not good at all with NBT, so I'm kinda stuck. Lol

 

I know it's nothing, but it's just to show an example of the variables and stuff. Here is what I have:

@Override
public void onUpdate(ItemStack itemStack, World world, Entity entity, int i, boolean bool)
{
	EntityPlayer player = (EntityPlayer)entity;


}
