Check if a player is wearing a full suit of armour [1.15.2]

[sccreeper]

I am trying to make a mechanic where if a player is wearing a full hazmat suit they do not get poisoned.

My current way of doing it is this:

if((livingEntity.getItemStackFromSlot(EquipmentSlotType.HEAD) == new ItemStack(RegistryHandler.HAZMAT_HELMET.get())) && (livingEntity.getItemStackFromSlot(EquipmentSlotType.CHEST) == new ItemStack(RegistryHandler.HAZMAT_CHESTPLATE.get())) && (livingEntity.getItemStackFromSlot(EquipmentSlotType.LEGS) == new ItemStack(RegistryHandler.HAZMAT_LEGGINGS.get())) && (livingEntity.getItemStackFromSlot(EquipmentSlotType.FEET) == new ItemStack(RegistryHandler.HAZMAT_BOOTS.get()))) { return; }

but

1) It isn't working

2) It looks very janky and I don't like it.

Probably you should use ItemStack::equals for comparing itemstacks

[poopoodice]

Compare ItemStacks using some provided methods in ItemStack (I don't remember what they're called), but you should be checking if their Items are equal (which == is fine), not the ItemStacks.

ItemStack has no equals method.

Oh, that's sad:(
But yeah, == is likely to not work here.

Got it to work with this code:
 

            if(e.player.inventory.hasItemStack(new ItemStack(RegistryHandler.HAZMAT_CHESTPLATE.get()))) {
                if(e.player.inventory.armorItemInSlot(2).getItem() == RegistryHandler.HAZMAT_CHESTPLATE.get()) {
                    e.player.removeActivePotionEffect(Effects.POISON);
                    e.player.removeActivePotionEffect(Effects.NAUSEA);
                    LOGGER.log(Level.INFO, "I works");
                    return;
                }

And yes I know I could check for both conditions with the && operator.
This post here helped a bit didn't realise armorItemSlot had other methods.
