So, I've been having trouble detecting what stack is in the slot on my custom player inventory. I need this to determine whether or not to render my model on the player. I couldn't seem to find any ways of doing this, and would appreciate some help!

Surely you know how to access your custom inventory for a particular

EntityPlayer

? Once you have a reference to the inventory, you just need to check each slot to see if it contains the item. If the item can only be placed in a particular slot, you only need to check that slot.

I do, but my problem is that in my Layer Render, when referencing this; it is always null. The entity is the player, it apparently creates an instance of the Inventory just fine. But, the stack is null, even though I am checking the correct slot.

 

Method:

private ItemStack getBackpackInSlot(EntityLivingBase entity) {
    	ItemStack stack = null;
    	
    	if(entity instanceof EntityPlayer) {
    		System.out.println("Entity was player!");
    		
    		EntityPlayer player = (EntityPlayer)entity;
    		InventoryWeightLimit inv = new InventoryWeightLimit(player);
    		
    		stack = inv.getStackInSlot(inv.SLOT_BACKPACK);
    	}
    	
    	return stack;
    }

 

Perhaps this is because I am only calling it client side? Would I need to send a packet from the server to tell the client what is there?

That's what I thought. I am guessing I would send the packet to the client every time the inventory updates?

In my opinion, you would be better off trying it first, and asking questions later

You're right about that. I do tend to ask questions about something, try it, then revert my question once it's completed. Thank you everyone!
