First Year with Java, Help Requested

[ccresta1386]

We are also in our first year and need help with programming. Our forward/backward and rotation works but strafing does not work.

 
    drive = new RobotDrive(1, 3, 2, 4); 
    driverStick = new Joystick(1);
    shooterStick = new Joystick(2);
    robotHeadingGyro = new Gyro(1);


double rotation = driverStick.getZ()*-1 / 2;                                                if (driverStick.getRawButton(3)){
rotation += .4;
 }else if(driverStick.getRawButton(4)){
rotation += -.4;
      }
               
drive.mecanumDrive_Cartesian(driverStick.getX(),
rotation,
driverStick.getY()*-1,
0);// we plan on putting a gyro in when the strafe works
