NAME

radar − flight controller’s view of the Ethernet dogfight

SYNOPSIS

/usr/people/demos/radar [ −i infile]

DESCRIPTION

The radar demo allows passive observation of the dog(1D) environment.  The radar operator sees a simulated radar screen showing the location, aircraft type, speed, direction, and altitude of each aircraft in the game.  A message facility allows the radar operator to send messages to the pilots. 

The program asks your name and broadcasts it to the dog world.  The initial display is a help menu.  Any key starts the program.  At any time when using the demo, the h key brings back the help page. 

The z and x keys increase and decrease the field of view.  The arrow keys move the point of view one square in the indicated direction. 

The right mouse button allows the mouse valuators to drag the image.  Press the left or middle mouse button for a prompt to send a message to the plane nearest the cursor or the whole world respectively. 

Display

The display shows a stylized view of the dog runway environment.  Each aircraft’s position is represented by an isosceles triangle pointed in the direction of the plane’s heading.  The vector from the front of the triangle shows its course and speed.  The trail of dots shows where the plane has been for the past 16 seconds.  Each plane has an ID block including the name of the pilot, the type of aircraft, the airspeed in knots, the sign of the rate of climb, and the altitude in hundreds of feet.  Sidewinders are shown as red blobs.  Rockets are orange, cannon shells yellow. 

Airshow Option

The −i option reads the aircraft positions from infile. infile should be created by using the −o option to dog(1D). This allows passive observation of the “airshow” recorded in infile. Broadcast messages are not of much use in this mode.
