Scripts

Hello, I need help with a script, but I don't know how to create it. When interacting with a specific object, a dialog should appear, similar to the one from the messagebox command, but with multiple answer options. Thank you in advance to whoever writes the script for me. And another question: is it possible, and if so, how can I make it so that the script executes the following command: the hero can move around the map and explore areas, but only a small portion of the map around the hero is visible, and the area beyond the hero's viewing radius is black. This would allow me to create a labyrinth where the hero can only see a small area, and all the places he has been will not be visible on the map. I hope you understand what I'm asking, as I'm not very good at explaining my idea.
