BGE bug fix (good for 2.47): SetParent actuator did not work on dynamic objects. Dynamics will now be disabled automatically and the object will be set ghost for the duration of the parenting; this is to avoid static interaction with the parent object. The dynamic state is restored when the parenting is removed with RemoveParent actuator. This fix also applies to setParent() and removeParent() python functions.

BGE bug fix (good for 2.47): remove static-static collision messages on the console since previous SetParent fix. The physical object is set to static+ghost while the object is parented. This behavior will be made optional in a future release. The DisableDynamics actuator will also make the object static except that the ghost/non-ghost flag is preserved.

BGE patch: dynamically update the coumpound parent shape when parenting to a compound object. This patch modifies the way the setParent actuator and KX_GameObject::setParent() function works when parenting to a compound object: the collision shape of the object being parented is dynamically added to the coumpound shape. Similarly, unparenting an object from a compound object will cause the child collision shape to be dynamically removed from the parent shape provided that is was previously added with setParent. Note: * This also works if the object is parented to a child of a compound object: the collision shape is added to the compound shape of the top parent. * The collision shape is added with the transformation (position, scale and orientation) it had at the time of the parenting. * The child shape is rigidly attached to the compound shape, the transformation is not affected by any further change in position/scale/orientation of the child object. * While the child shape is added to the compound shape, the child object is removed from the dynamic world to avoid superposition of shapes (one for the object itself and one for the compound child shape). This means that collision sensors on the child object are disabled while the child object is parent to a compound object. * There is no difference when setParent is used on a non-compound object: the child object is automatically changed to a static ghost object to avoid bad interaction with the parent shape; collision sensors on the child object continue to be active while the object is parented. * The child shape dynamically added to a compound shape modifies the inertia of the compound object but not the mass. It participates to collision detection as any other "static" child shape.

BGE patch: Add damping and clamping option to motion actuator. 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.

For bullet use the new setUnscaledRadius() function to change sphere radius. In pPreparation of a Fh constraint actuator: - Add KX_IPhysicsController::GetRadius() - Fix implementation of KX_BulletPhysicsController::GetVelocity() (velocity at a point in geometric coordinate) - Don't try to set velocity on static object (Bullet will assert) - Add KX_GameObject::GetVelocity() for C access to local velocity

Lots of stupid warning fixes: Added newlines at end of a bunch of files that didn't have them. removed a couple of unused variables and an extra ';' (Also removed config.h crap from these files) Kent
