Action RPG Inventory System

First let me say - what a great system! You have put a lot of work into this and I thank you for making it so affordable!

Second - I’m brand spanking new to it so I’m sorry if this is obvious or been answered before but - I want to make a usable actor - a Key - that opens another usable actor - a door — The key has a serial number and so does the door - so if they match the door opens - now I actually already have all that except for where I put that logic connected to the usable actor - I tried overriding the “ActorUsed” and a couple others - but then the item isn’t picked up from the level LOL s I am missing some basic step

Can you point me in the right direction?

Thanks a ton!
