I'm trying to create a command that Changes the nbt data of the currently held item. Ive gotten to the point where everything works except for this line. EntityPlayer player= sender.getDisplayName(); @Override public void processCommand(ICommandSender sender, String[] args) { String output = String.join(" ", args); if(args.length == 0) { throw new CommandException("no name defined"); } else { EntityPlayer player= sender.getDisplayName(); ItemStack stack = player.getHeldItem(); addInformation(stack, player, output); } } public void addInformation(ItemStack istack, EntityPlayer player, String itemname) { NBTTagCompound tag = istack.stackTagCompound; if (tag == null) { tag = new NBTTagCompound(); tag.setTag("display", new NBTTagCompound()); istack.stackTagCompound = tag; } tag.getTag("display"); tag.setTag("display", new NBTTagCompound()); NBTTagCompound tagname = tag.getCompoundTag("display"); NBTTagList name = new NBTTagList(); name.appendTag(new NBTTagString("§b"+itemname)); tagname.setTag("Name", name); }
