A problem I've got into

Hey guys, I’ve made a some kind of minimap, now I’m nearly new at blueprints at all. and I would like to attach a key to this minimap to make it appear and disappear. can anyone explain me a bit so I can learn?

You’ll probably want to take a look at - YouTube

especially at around 5:40

Basically add an event for the key you want pressed and then make it do what you want. Seems like you just want to toggle visibility
