I downloaded the Autobase script for C&C3 and check the script.
So i try to figure out how it work for Ggenerals.
Im trying to spawn units at the start from the game.
I having difficulties with the faction.

Is it possible for multiplayer or only skirmish?

How to setup/edit the players list?

How to setup/edit teams?

Out of curiosity, what does this autobase script do?

Well in C&C3 Multi Player the script spawn a complete base for every player whatever the faction is.
I can't remember how i get it, A friend's friend made it.
In other words, you can spawn all kind of units/structure at the start of the game for all players, not related to the faction they choose.

Of cource you can take looping random timers and spawn wenn ever you want, but that''s another thing :)
