Vex Code error (V5)

#1

I have sucessful codes with two controllers, however, when I moved it to one controller the VexCodeInit() lines started to cause errors. I have tried to reload the program, but that has not worked. Can anyone potentially tell me what is wrong with the code?

#include "vex.h"

using namespace vex;

competition Competition;


void pre_auton(void) {
  // Initializing Robot Configuration. DO NOT REMOVE!
  vexcodeInit();

}


// START AUTONOMOUS
void autonomous(void) {

 // Display on screen
 Brain.Screen.print("Autonomous has started");

 // Move forward
 FrontLeftDriveMotor.rotateFor(0.9, rotationUnits::rev, false);
 FrontRightDriveMotor.rotateFor(0.9, rotationUnits::rev, false);
 BackLeftDriveMotor.rotateFor(0.9, rotationUnits::rev, false);
 BackRightDriveMotor.rotateFor(0.9, rotationUnits::rev);

 }

// START DRIVER CONTROL
void usercontrol(void) {
  // User control code here, inside the loop
                                                                                        
 
#include "vex.h"

using namespace vex;


 // Initializing Robot Configuration. DO NOT REMOVE!
 vexcodeInit();
 
 // Display that the program has started on the screen
 Brain.Screen.print("Driver control started");

 // Create and infinite loop so that the program can pull remote control values every iteration
 while(1){
   
    // Set motor speeds
    int clawSpeedPCT = 40;
    int driveSpeedPCT = 75;

Looks like you copy-pasted a previous project into the usercontrol segment. The include, namespace, and vexcodeInit() lines are already at the top of the file, so they aren’t needed again inside your usercontrol function.

In other words, delete these lines:

// START DRIVER CONTROL
void usercontrol(void) { //keep the loop
  // User control code here, inside the loop
                                                                                        
 
#include "vex.h" //DELETE ME

using namespace vex; //DELETE ME


 // Initializing Robot Configuration. DO NOT REMOVE!
 vexcodeInit(); //DELETE ME

I used the fixes you said and it caused a lot more errors because now it is saying all the variables are not defined

hm, do you think you could upload your entire project? I think you probably have an error between files. It builds fine for me.

Make sure you deleted the include in the usercontrol and not the one at the top of the file.
