A I certain starting points.

Okay, I have been playing BeamNG. Drive for a few months now and I know how the game works. So my problem or if this is even possible in the game, "How can I make the Script AI start moving, when my car that I "Myself" am driving, passes a certain point or an invisible obstacle that causes the directed AI vehicle to start moving because, I like making stunt movies or these cool scenarios and I do car chases and other things, but the car chases without traffic or trucks carrying cargo, during a chase scene, seems pretty bland and it just feels like the city is a ghost town or something. Please if someone knows how to do this, please reply to this. Thank You!

The yellow passes the invisible wall.... ....and the directed A.I vehicles start moving

 

All I can suggest is pause the game when you want the AIs to set off, then go through each vehicle and set their AI to "Traffic". It works most of the time, but you might have to change their settings to get it to work (unless you set awareness to Off, AIs won't drive a damaged vehicle).

 

Hello there, what you're asking for isn't possible in BeamNG. There is no certain "trigger option" in the Scrip AI that is based on another car - or even time based. What I usually do is the following: I have car A and B. I open the F11 World Editor and then the Script AI. I start recording of Car A. I finish. Then I press PAUSE, I click record for car B and click PLAY for car A. I end the PAUSE mode and record car B.

For movies, when you actually want car B to start driving when car A passes, you'll have to drive car B yourself. It's the easiest and only way.
