Collectibles

In my game, whenever a character re-enter a room that they already got a collectible out of, the collectible reappears. I want it so that when you grab a collectible, it doesn’t reappear even if you re-enter a room.

  Ah, so you'll want to save the fact that collectible A was collected, and collectable B wasn't. To save information between play sessions or between scenes, you'll need to use "persistent" variables.

  You can learn everything about variables here: https://www.youtube.com/playlist?list=PLX3qX-yI9vm4Dgo5NpTd0HcHYhnCJXNQA The first 2 will give you the basics and teach you about persistence.

  You could use 1 variable per collectible, but you can only have 128 "persistent" variables per dream. So it's usually a good idea to use more advanced logic to save more of the collectibles into a variable at once. "Using the 25-bit chip" will get you to how to use a piece of logic I made specifically designed for getting a persistent variable to work for many collectibles at once. And the other "advanced partial variables" teach you how that method works.

  Ok. How exactly would I program a coin to persist in dream once it’s collected? Would I have it connected to the destroyer somehow?

  Yep! When the scene starts, you check what the persistent variable says. If it says it's been collected, destroy the thing that was already collected.

  That 25-bit chip video shows you how.
