ya know... I've been wondering about this too for a long time. I'd really like to know what the rescue function is, and I'm sure if someone answered this it'd prove helpful to many people, or at least 2 :ggani:
Its klikein sc you get close to a unit and it becomes yours aka rescued this will detect if you have rescued a unit. you can set if a units of the player can be rescued by the player in the editor set it to rescuable.
well, back to the topic....
the trigger for rescuing a unit gives a unit to a certain player...
its not like starcraft where u can just make a player rescuable...
