Apparently:
But, ofc, more will be needed. You can probably drop stuff on target spot that is already taken, and you will be unable to pickup items that are dropped. The dropbox actor btw since I forgot to include it:
Reacts only to Visibility channel - that’s the setting to manipulate if you want to pick up items again. The whole thing can be done more organically / logically - but we’d need to know how the rest of the system is supposed to work. I’d leverage the interface more, for sure. Or even encapsulate the pick up / drop behaviour in a dedicated component so it can be added to all sort of actors.
