I want the convoy or the plane to move along a specific route in the editor, but the convoy will drive on the lawn every time and will not drive along the road. Secondly, the plane will fly randomly. I would like to ask, how to assemble each independent plane or helicopter into a formation in the air after taking off? (For example, there are 5 helicopters in the airport, and then they form formations in the air just like the movie Black Hawk Down.) Then, how to get the mechanized infantry group into the vehicle? Or let different infantry groups enter a convoy of 2-3 cars or armored personnel carriers? (Similar to those in the Arma 3 grand scene videos made by some bloggers on YouTube or the military convoy that often appears in movies), thank you!
