[AI] Enable campaign AI for myself

[Barade]

Hi,

is it possible the enable a campaign AI script for myself? I tried to start a campaign AI script it with a trigger for my player but nothing happened. The workers did not do anything.
There is the native:

native SetPlayerController      takes player whichPlayer, mapcontrol controlType returns nothing

but I suspect it will crash the game when I try to change myself to a computer player?
I don't want to have a second player with shared control/resources etc.
I want to run the AI for my player and exclude certain units from it.
