How to make particles move and rotate with an actor?

I have a car with a smoke effect from the engine pipes. I used a particle behavior, and it works great when my car drive forward, but the problem is when the car rotate. When the car rotates the smoke gets out of its position instead of following the car. Can anyone help please?

    Could you make an attribute so when the car rotates the direction the particles are being spawned in changes as well?

    30*cos(self.rotation) and 30*sin(self.rotation) in the x and y emiiter offset in the particle behavior

    is your smoke emitter not constrained to the car actor

    when your car rotates you can read its self.rotation value and then setup some rules in the smoke emitter to make it rotate

    thats a starting hint for you :-)

    But how is it then possible to offset the particles from the actor?

    @sirbull

    X: cos(self.rotation)*offsetDistance
    Y: sin(self.rotation)*offsetDistance

    Hey guys! Any idea how to get this to work when the actor is rectangular (not square)? Or if the actor is square but the visible image isn't centred in the actor (the actor is not symmetrical)?
