(added the script here too)
 
(Someone forgot to change this. The createCamera and setCamera calls are no longer a part of the testing library, but the graphics one. I have updated it accordingly.)

Notes

Script avoids directly changing the position data of the player ship to avoid several potential physics problems. Handles 3D targeting controls should proper models be included to the mission. Script also removes all hostile fighters and bombers that have passed the player ship and kills them. Radar-set-max-range SEXP should be used to prevent the targeting of the disposed ships.
