It is not recognizing the RRSpeedPCT variable

#3

Could you post where RRSpeedPCT is referenced within the code? If this is your entire code, then you never actually reference RRSpeedPCT.

#4

It says the RRSpeed variable is undefined. This is to drive with joysticks.

wait(20, msec); // Sleep the task for a short amount of time to
                // prevent wasted resources.

Where do you use RRSpeed? I see where it is defined but not where you use it.

#7

The Axis Values. I got rid of the PCT

#8

Oh, you want to drive with Joysticks? In that case, just defining an integer for the speed shouldn’t automatically generate code for the joysticks. Instead, assuming you want a tank drive, I would personally go something along the lines of

int RSpeed = Controller1.Axis3.position();
int LSpeed = Controller1.Axis2.position(); //you don’t need each individual motor to be a variable if you just reference the same variable for both wheels on one side of a drive train.
RF.spin(directionType::fwd, RSpeed, velocityUnits::pct);
RR.spin(directionType::fwd, RSpeed, velocityUnits::pct);
LF.spin(directionType::fwd, LSpeed, velocityUnits::pct);
LR.spin(directionType::fwd, LSpeed, velocityUnits::pct);

But yeah, if there is an error, which line is it on?

Do you have a screenshot of the error?
When you use
int RRSpeed = Controller1.Axis3.position();
It should not be producing a variable is undefined error if you call it in the while loop. It should only be an error when you call the variable outside the while(true) loop

It works thank you very much
