Starting location and win conditions

I guess it's obvious, but I cannot find it in any of the tutorials.

I want to make an hero map only, so there should be no starting location. Each player will control only one hero and nothing else. But each time I save the map I need to create those location. Is there a way to remove this condition ?

I cannot find the win condition setting either.

Thanks for your help

Go to the trigger editor and remove the melee trigger, however you must always have a start location-- but that will make things fine.

If you remove the "Melee - Create Starting Units" [sic] action from Map Init, then it won't make the melee units at the start location. You still need the start location in the map, though. Just think of it as a place where the player's camera will start.

That was exactly what I was looking for, thanks a lot
