And this is the part of the class:

Tha Part (open) Tha Part (close)

Code:

        ItemStack item = e.getItem();

        if(this.config.getBoolean("FunBalls.Enabled")) {
        if(itemmeta.hasDisplayName()) {
            if(itemmeta.getDisplayName().equals(ChatColor.translateAlternateColorCodes('&', this.config.getString("FunBalls.Name"))) && item.getTypeId() == this.config.getInt("FunBalls.ID")) {

        }

    }

Thanks in advance

 

@WaveHD I was going to insist that you either provide the entire class or point out which line was line 110, but that's not necessary right now, I see the problem instantly.
There's not always an item. A player may have punched, or right clicked, with an empty hand. Furthermore, InteractEvent covers pressure plates as well, so they might not have even clicked.

Code:java

if (!e.getItem().equals(null))

 

Thanks!

The line of the problem is on

Code:java

ItemMeta itemmeta = (ItemMeta)item.getItemMeta();

Now I try to do what you told me

 

@WaveHD Yeah, so just check if (item.equals(null)) first.

 

Ok, ALL SOLVED
Thanks a Lot!
