A few questions about scripts.

In general, I decided to create a few scripts, and I have some questions, even though I studied the manuals for a long time. 1. A simple MessageBox. I created a txt file, but what path should I specify in the script to access it? What is the initial folder, and do I need to include the file extension? 2. This isn't exactly about scripts, but it's related. How can I create a quest where the goal is to capture multiple identical peasant huts (like in the first map of the Hammers of Fate)? 3. How can I make it so that when an enemy hero crosses a region, they run from one place to another, while the camera follows them, preventing the player from controlling them? 4. How can I make certain areas on the map initially visible?
