Testing for partial armor

I want to test for players wearing armor as defined in a config.

Here is the code involved:

Code:

    public boolean isProtected(PlayerInventory inv, String condition) //"condition" is the header of the section containing "Protection_Required"
    {
        ItemStack helmet=getConfig().getItemStack(condition+".Protection_Required.helmet");
        ItemStack chestplate=getConfig().getItemStack(condition+".Protection_Required.chestplate");
        ItemStack legs=getConfig().getItemStack(condition+".Protection_Required.legs");
        ItemStack boots=getConfig().getItemStack(condition+".Protection_Required.boots");
        ItemStack held=getConfig().getItemStack(condition+".Protection_Required.held");
       
       
        return (inv.getHelmet().equals(helmet) || inv.getChestplate().equals(chestplate)
                || inv.getLeggings().equals(legs) || inv.getBoots().equals(boots) || inv.getItemInHand().equals(held));
    }

Here is the config involved:

Code:

    Protection_Required:
        helmet: NONE
        chestplate: LEATHER_CHESTPLATE
        legs: NONE
        boots: NONE
        held: TORCH

However, when I try to run it, I get a NullPointerException. I know, it's because I'm checking armor slots for items that are technically non existent, but is there any way around this?

Thank you,

@xlr20ice
Maybe add a null checker?

 

@Halmerson
Wouldn't I have to add a null check for every slot I want to check though? Or would it be part of the return statement?

 

yes of course you have...
if (inv.getHelmet() != null && inv.getHelmet().equals(helmet)) return true;
if (inv.get...
and so on

 

@Lordloss either do that, or instead of NONE try AIR
