Question

支架位于int main（）之后。这是针对vex机器人技术的。我正在使用VexCode V5来编程机器人。这是C ++。该代码是允许机器人向前和向后行驶，并使用所需的特定类型的轮子进行侧面方式。如果我没记错的话，那些轮子的名称是mecanum车轮。

{
 Motor1.spin(forward);
 Motor2.spin(forward);
 Motor3.spin(forward);
 Motor4.spin(forward);

 int main ()
 {
  while(true)
   {
     // REMEMBER:
     // m1(x, y) = y + x
     // m2(x, y) = y - x
     // m3(x, y) = y + x
     // m4(x, y) = y - x

     // motor[Front_Left] = 1
     // motor[Front_Right] = 2
     // motor[Back_Right] = 3
     // motor[Back_Left] = 4

     // vexRT[Ch1] = Left/Right
     // vexRT[Ch2] = Up/Down
     // vexRT[Btn5U] = Counter-Clockwise
     // vexRT[Btn6U] Clockwise

     motor[Front_Left] = vexRT[Ch2] + vexRT[Ch1];
     motor[Front_Right] = vexRT[Ch2] - vexRT[Ch1];
     motor[Back_Right] = vexRT[Ch2] + vexRT[Ch1];
     motor[Back_Left] = vexRT[Ch2] - vexRT[Ch1];

     if (vexRT[Btn5U] == 1) {
       // rotate counter clockwise
       motor[Front_Left] = -127;
       motor[Front_Right] = 127;
       motor[Back_Right] = 127;
       motor[Back_Left] = -127;
       wait1Msec(50);
       motor[Front_Left] = motor[Front_Right] = motor[Back_Right] = motor[Back_Left] = 0;
     }
     if (vexRT[Btn6U] == 1) {
       //rotate clockwise
       motor[Front_Left] = 127;
       motor[Front_Right] = -127;
       motor[Back_Right] = -127;
       motor[Back_Left] = 127;
       wait1Msec(50);
       motor[Front_Left] = motor[Front_Right] = motor[Back_Right] = motor[Back_Left] = 0;
     }
   } //END OF WHILE LOOP
 } //END OF TASK MAIN
