I've tried making a shop before, and it failed really badly, so I want to start over again with new concepts. I've tried magnitude, .touched event, region3 and it did not work as I wanted it to. I'm trying to make something similar like the saber simulator shop. There is like a part (cylinder) and when you touch it opens, but if you close it while your still in the circle, you have to re-enter the circle or jump to re-open the shop. Please suggest some concepts that I should learn. Thanks!
you should learn about remote events, how to clone guis and the difference between local and server if you don't know already
