How to make my jetplane fire follow the correct rotation

Questions & Answers
1

I have this jetplane that create some fire behind it you know and i add the fire in a prefab and once i move the jetplane it doesnt follow the rotation of the jetplane

I set the fire to go down but once my jetplace makes a left or right the flames just keep going downwards

How can i make the fire follow the rotation of the jetplane?

I assume the fire is a particle system so the easiest way is just to parent the jet plane to the particles and then set the local particle velocity.

If you want to manually set the rotation ( you will still need to set the local velocity) then you set it to the opposite of the move direction.

 var rotation : Quaternion = Quaternion.Inverse(jetplaneTransform.rotation);
 particleSystem.transform.rotation = rotation;
