I figured out how to make the trip wires in the FDF mod actually work! Well, the flares anyway. The other type just kill your player. Here's what to do....
Place a "flare trip wire" where you want to. Then place a Game Logic really close to it. Preferrably on top of it. Then set up a trigger and place in it's activation field, "('name of your trip wire here') distance ('name of your Game Logic here') > 100"...You can then have it alert the base!! If you give it a boolean, example...once the trip wire is tripped, have "obj99 = true", add a 5 second delay to give the flare actual time to alert the base, and have onother trigger ready to watch for when obj99 = true. Have an alarm sound and all of the enemies behaviour change to aware, and wah-lah...instant alerted base...
These trip wires are alot of fun...especially at night!
Good mission making to all...
