[Trigger] fighting scenario when your units encounter them

[Just Another Dude]

So the last question that I asked is tied with the AoS type of game, but now I'm working on a campaign. One of the scenarios in mind is when you enter a certain region, your camera will be moved to the 2 group of units fighting, one of the groups are rescuable. I already know how to do the camera panning but I don't know how to do the trigger where the 2 units don't fight until you enter the region. Help!

You could use the pause unit action or just make the units invulnerable at the start of your map.
Once your scenario is triggered you just unpause the units or make them vulnerable.
