Use actions are actors of a specific class that can be assigned to inventory items. If an item is used the
use action is spawned and will call its event (for example compare key IDs to open a door). The easiest
way to create your own use action is to duplicate BP_UseAction_Key and replace the existing “Event
Use Event” by your own use event. After the “Event Use Event” node place your code and then don’t
forget to destroy the actor afterwards.
Please have a look at the example use action to see how you can use the “Discard when Used?” value.
