Torque or Velocity on child object?

Game Engine Game Engine Support and Discussion

I just tried to fiddle with making a helicopter and tried to apply angular velocity or torque on to the rotor which is parented to the helicopter (body).

However nothing happens when I do so. If I put rotation directly, it does turn only the rotor but neither Velocity or Torgue works.

I tried rigid body and dynamic object modes both.

Any suggestions?

the child object is probably not dynamic, or the script isn’t running the code.

Velocity and Torque are for physics objects only (dynamic, rigid body, softbody).

As a rotor will never move your helicopter it’s motion is just show. So you can simply use Rot.
