Hi,
I am new to 3d Gaming and need to know a basic thing.
I want to rotate an object (say a pedal ) about a fixed point and make it hit a ball which should then fly off in a direction and with a speed which is in accordance with laws of physics.
In Unity3d what I have done is attached a sphere collider and a rigidbody to the ball and a mesh collider and a rigidbody to the object (the pedal) with gravity turned off on it.
I call a transform.rotate() on the object whenever I want to hit the ball (and then bring it back to the original position in the next frame), but this only makes the object treat the paddle as a static collider in the new rotated position and disregards all interactions vis-a-vis the physics.
For the expected behviour do I have to apply a torque to the paddle to make it rotate ?

Yes. Generally, you don't get the expected physical behaviour when you move rigidbody objects by setting their position rather than moving them with forces and torques. _________________ None of you understand... I'm not logged-in here with you - YOU'RE LOGGED-IN HERE WITH ME!
