Add an interactive 1st-person camera to the project
Right-click the grass area to place the 3d cursor where you want to place the camera
and add the Cam1StPerson object there, as shown in the video.
Double-click the Cam1StPerson item in the Object List and configure the object as shown.
Add the gravity object (G-Force) to the project.
Select the Cam1StPerson object again in the Object List,
link it to the RigidBody object (to enable collision detection with the gatehouse model)
and to the G-Force object (to apply gravity force to the 'character' body).
