Hye, im a newbie in game developing. So, to make it short, i'm making a 2D platform game that add a little gamification value in it, so i'm trying to make that, if player have collected all the items, then they can continue next level. For example, they have to collect a,b,c, and d to proceed but they only have a,b and c, so they can't go next level. I wanted to make a pop up that shows what they have collected. I've tried looking up for tutorials, but i didn't bump into one.
