This patch introduces two options for the motion actuator: damping: number of frames to reach the target velocity. It takes into account the startup velocityin the target velocity direction and add 1/damping fraction of target velocity until the full velocity is reached. Works only with linear and angular velocity. It will be extended to delta and force motion method in a future release. clamping: apply the force and torque as long as the target velocity is not reached. If this option is set, the velocity specified in linV or angV are not applied to the object but used as target velocity. You should also specify a force in force or torque field: the force will be applied as long as the velocity along the axis of the vector set in linV or angV is not reached. Works best in low friction environment.
