Remove items with custom display name?

Thanks.

Just a heads up, never make a thread, and just say "Look at Title" because then all replies you get will be "Explain", "Don't do that", or they'll tag a staff, and your thread will be removed.


Loop through inventory
if itemstack has item meta
if itemmeta's display name is "Name"
set Type to Air

 

How am I supposed to explain that? I want to remove an item from an inventory with a custom display name. Explained.

I came up with this code but it throws NullPointerException on the .getType check.

Code:

for(ItemStack i : player.getInventory().getContents()){
              if(i.getType() == Material.STONE_BUTTON){
                    player.getInventory().removeItem(new ItemStack(Material.STONE_BUTTON));
                    player.updateInventory();
                }
            }

 

Connor2weirdness, what you need to do is this:

Code:

ItemStack item = new ItemStack(Material.STONE_BUTTON);
ItemMeta im = item.getItemMeta();
im.setDisplayName("DisplayName");
item.setItemMeta(im);

and then make a for loop to get all the contents, then use the isSimilar method which checks if an itemstack is equal to another itemstack but ignores how much there is of that item - if the itemstack item is similar to the itemstack that you just got from the for loop, use the removeItem method to remove the item from the for loop.

 

Thanks.

When looping through the inventory make sure the item stacks type != null

 

That is what creates the NullPointerException?

If remeber right, its that or the item stack its self
