Passing a motor as an argument in a function

Hello, I am trying to pass a speed controller (victor) as an BYREF argument in a function and set its value, however, the motor wont turn on and I get no errors. Here is what it looks like:

Code:

void SpecialControl(SpeedController &Motor); /* prototype */

class Robot : public SimpleRobot

{

        Victor InitialMotor;

        public:

                Robot(void):                // these must be initialized in the same order 

                InitialMotor(1)

        {

                GetWatchdog().SetExpiration(0.1);

        }







void OperatorControl(void)

        {

                GetWatchdog().SetEnabled(true);

                SpecialControl(InitialMotor);

        }

};



void SpecialControl(SpeedController &Motor)

{

        Motor.Set(1);

}

Thanks in advance.

Re: Passing a motor as an argument in a function

Give this a shot:

Code:

void SpecialControl(SpeedController *Motor); /* prototype */

class Robot : public SimpleRobot

{

        Victor *InitialMotor;

        public:

                Robot(void)

                {

                       InitialMotor = new Victor(1);

                       GetWatchdog().SetExpiration(0.1);

                }





                void OperatorControl(void)

                {

                     GetWatchdog().SetEnabled(true);

                     SpecialControl(InitialMotor);

                }

};



void SpecialControl(SpeedController *Motor)

{

        Motor->Set(1);

}

I have tried that, and it gives me these errors:

Quote:

error: cannot convert `Victor' to `SpeedController*' for argument `1' to `void SpecialControl(SpeedController*)'

Thanks in advance.

Re: Passing a motor as an argument in a function

Look carefully at this line, and make sure you didn't leave out anything.

Code:

Victor *InitialMotor;

Ah, finally, that compiles... I will see if it runs on the robot tomorrow. Thanks so much...
