Hey Crowey, it's me Zipper from 22SAS.
Anyways, there's a simple solution to this. To get the civilians to stick their hands on their head, use this code in a trigger with a condition of
true, a waypoint or a script:
unitname switchMove "TestSurrender"
That will put the civilians hands behind their head.
To make a soldier stand their aiming at him, obviously you first need to place him in front and facing the civilian. Now put the following in his init line:
this disableAI "ANIM"
To make him move again, simply use this in a trigger, waypoint or script:
unitname enableAI "ANIM"
Hope that helps.
