Current questions and answers regarding the map editor.

It can be done with a script. If there is an unused player on the map, the script needs to assign the hero the color of that player. Otherwise, it's impossible.

For example, on the map, all players are present except for the red one. We assign the hero to any of the seven available players. Then, using a script, we make him red. Since there is no red player, the game will make the hero neutral, but you can't directly make him neutral. It will result in an error.
