The last Humangeo class

Ok... it is really sad to say goodbye, but the good thing is we can still meet in the School!
I have a Robotic competition this Sunday and Hope I can get the ticket of the state Championship! Here are some code I am using:
#include "robot-config.h"

/*  You may want to perform some actions before the competition starts.      */
/*  Do them in the following function.  You must return from this function   */
/*  or the autonomous and usercontrol tasks will not be started.  This       */
/*  function is only called once after the cortex has been powered on and    */
/*  not every time that the robot is disabled.                               */

void pre_auton( void ) {
  // All activities that occur before the competition starts

}

    vex::task::sleep(20); //Sleep the task for a short amount of time to prevent wasted resources.

    Competition.drivercontrol( usercontrol );
