I am getting an error and would know how to fix it,

[BrainDeadLabz]

Everything is working as intended but I am getting this error:

Blueprint Runtime Error: “Attempted to access index 0 from array Inventory of length 0!”. Node: Update Quantity Graph: Add Item Function: Add Item Blueprint: InventoryComponent

This is my code:

What do I need to do to get rid of the annoying error?

Hey @BrainDeadLabz!

You need to post the insides of those custom functions! What’s happening is you’re trying to get an index of the Inventory array that isn’t there, giving you a null reference exception. Which, if this code is correct, shouldn’t happen UNLESS the bool output of your previous function was backwards. Give looking into that a go!

Here is the check existing item function:

and here is the UpdateQuantity Function

Not sure what’s going on I’m so confused and been trying to get this working since 7am this morning… any help would be appreciated

EDIT: ADDED THIS BIT OF CODE:

Now it’s fixed…
