Scripts in "Heroes".

However, I'm a complete newbie when it comes to mapmaking in many games... And what happened to me in other map editors happened here too – I don't know how to use scripts when creating a map (for example, so that the difficulty level chosen by the player affects not only the amount of resources and the strength of monsters but also the frequency of attacks by a certain faction on a particular castle, etc.). This problem really bothers me... Maybe someone knows how to "embed" and implement them? Or is there some program for this purpose? I will consider and take into account all options and will be grateful for any help.
Thank you in advance... :smile05:
