Scripts

Looks like it's done through SummonCreatures... There was definitely a function for it in the manual. Best regards.

AddCreature(side, type, number, x = -1, y = -1);
Side - the faction, x and y - tile coordinates. Number - the number of creatures, type - presumably, the unit name. I'm not very good at combat scripts yet, so I can't say anything definitive, other than quoting from the manual. Best regards.

Thank you very much! Maybe I'm being annoying, but I have another question - is it possible to make the game remember the number of summoned creatures remaining at the end of the battle for a specific faction?
Best regards.
