Inventory counter help

Is there a way of counting the amount of say red wool in a persons inventory Spesifically items with data values which does not throw null pointers if the block doesnt have a data vlaue

Current code:

Code:

    public static int getAmount(Player player, int id, Byte itemdata){
        PlayerInventory inventory = player.getInventory();
        ItemStack[] items = inventory.getContents();
        int has = 0;
        for (ItemStack item : items) {
            if ((item != null) && (item.getTypeId() == id) && (item.getAmount() > 0)&&(item.getData().getData()==itemdata)) {
                has += item.getAmount();
            }
        }
        return has;
    }

 

Check if the data is null I guess, like you did with item.

 

in my experience when i tried to check if the data was null it threw an error at me, but i'm fighting through a similar situation rob

 

If everything else fails, just use try/catch.
Try comparing the data in the try block, if it fails itll only compare the ids in the catch block.

 

item.getDurability() would do if you don't mind the same effect on damaged tools.

Other than that, to avoid a too complex if statement, put another one in the first one where you sperately check for data if there is any.
