So far you have had us import the “Inventory.unitypackage” on the “Integration introduction”, but that does not include the “Clickable Pickup” script. So where is that script supposed to come from?
Edit
I found it in the “9 Action System.unitypackage”. I just imported only that script from there, renamed the namespace, configured the new cursor mapping. and got it to work. Still, was this the intended workflow of the course? It’s not explained.
