 Other games however require a third-person perspective of the character: In these cases you use a CharacterControl on a Spatial. This example also shows how to set up custom navigation controls, so you can press WASD to make the third-person character walk; and how to implement dragging the mouse to rotate.

If you need additional collision checks, add GhostControls to your characters and create a custom <<jme3/advanced/physics_listeners#,collision listener>> to respond.
