Question
I, wanting a computer border for when my player plays a game on the compute but i don’t know how to hide it until they access the computer or how to re-hide it when off the computer
You’ll have to provide a lot more information than that, even better if you can show some code examples, and better explain what you’re trying to achieve.
I can take a guess at what you are saying you want to do, but without specifics I suspect a guess is the best you are going to get.
Put your computer screen under a single node. When the player accesses the computer, turn visibility on. Turn it off again when they leave.
