| force | Components of the force in the X and Y axes. |
| position | Position in world space to apply the force. |
| mode | The method used to apply the specified force. |
Apply a force at a given position in space.
The AddForce function applies a force that acts straight through the rigidbody's centre of mass and so produces only positional movement and no rotation. AddForceAtPosition can apply the force at any position in world space and will typically also apply a torque to the object which will set it rotating. Note that for the purposes of this function, the rigidbody is just a coordinate space of infinite size, so there is no reason why the force needs to be applied within the confines of the object's graphic or colliders.
