Score keeper

The goal of my game is when you pick up a item you get a point, but if you touch a certain area or get all the items your points reset. How do I do this?

Extremely simple, just have it increment your score value by one whenever you want, and then make a collision volume and when the user collides with it, reset points to 0.

Yep trigger volume is what you want. On overlap cast it to your player character and then set his score to 0

How do I make the scoring system? I already figured the collision part out.

Yes use an “on overlap” event, and drag off from the execution node to set: ‘score = score + 1’

Plenty of youtube tutorials out there to explain how to use variables, i suggest you give them a watch.
