-The position of a kinematic RigidBodyControl is updated automatically depending on its spatial's translation. You move Spatials with a kinematic RigidBodyControl programmatically, that means you write translation and rotation code in the update loop. You describe the motion of kinematic objects either by using methods such as `setLocalTranslation()` or `move()`, or by using a <<jme3/advanced/motionpath#,MotionPath>>.
