Hey guys, I hope someone can help me with this. So I have made missions with the editor before and have a basic understanding of the editor and waypoints and things but I have a very specific thing I want to do in this mission. So there is a part where me and my team of spec ops have to do a joint operation with the cdf and take down a warlord, the cdf group is waiting a couple hundred yards to the south of the compound where the target is and I have a waypoint set for them to attack, but I want that waypoint to be triggered when I signal it. I was thinking I could do it with radio or something but I don't know how to set it up. Thank you in advance, also I was wondering if there was a way to put checkpoints in missions. Replies would be appreciated. Thanks.
