Scripts

Is it possible to use scripts to block off a part of the map from the player?

I was interested in this myself, but it seems like it's not possible.

Is it possible to build twice in a city in one turn? I.e., is there a way to unlock a city?

You can forcibly build a building in a city. Regarding unlocking: I haven't seen a special function for this, but who knows, maybe locking it using IsObjectEnabled and then unlocking it with the same function will reset some settings and allow you to build the building a second time? I think it's worth trying.

Is it possible to track when a hero interacts with a caravan?

Redhaven is our expert in getting the names of objects of a given type. If you create a caravan using scripts, you can choose a name for it, and then it will be no problem at all.
