I am currently setting up a campaign in the Eden editor where the intro has you in a slave state area. There are some "decorations" that are basically armed units patting down civs, aiming guns at them, ect. The point of these is to show you are in a slave state, but I wanted you to get shot for interfering if you got too close. I thought the simplest way would be to set the player to OPFOR so they get shot if they try walking near the area, but now I can't figure out how to script a way to change their side, can someone help me?
