Papers Please border game design assistance required

I am making a Papers Please esque border game. So far, I have working passports (using OOP for information that gets put into the document) and somewhat working stamps.

I have a few questions regarding what I can do and what would be the best design choice.

  1. The documents will be presented to an inspector at the border by equipping them and touching an invisible box at the border. How should I go about this? Should I spawn a physical passport/document that gets dropped inside the booth? Then, I need the documents to be draggable. How do I do that with a DragDetector?

  2. Should the stamps (Red/Green/Blue) be stationary (embedded into the map) or tools you can equip and use?

  3. How should I select border inspectors without using a group and group roles? (I lack the amount of robux for that)
