Digging deeper into Construct 2 to get some more puzzles in the point and click game I'm working on. I ran into a speedbump with implementing a letter-based lock for a door. Basically, I want a few small displays that show one letter at a time. Players can click a button/arrow to cycle through the alphabet in order, set the correct code, and unlock the door.
I've made smaller puzzles like this before, but it's easy to switch a few objects or sprites around when you're only working with a handful of symbols. With the entire alphabet, though, it's a different story.
Any suggestions on how to progress? I'm studying up on arrays now, but so far haven't seen much info about simply retrieving a static list and displaying it on the screen.
