Re: Still problem with classes...+img

It looks like you are trying to create an object for the "Drive" class....right??

I think you were trying to write:

RobotDrive *bba;

??

Maybe I'm missing something? Please elaborate.

Re: Still problem with classes...+img

Yes, im trying to creat a new object "Drive" (!!)

I defined a new object at the class "Drive" and i want to make a new
object in my code. Like "PWM" or "Jaguar" but from class that i created!

help :(

Re: Still problem with classes...+img

Mind showing us more of that MyRobot.cpp file you're using? If you could post that, along with your Drive.cpp and Drive.h files, then it'll be easier to figure out than working from just a screenshot.

Re: Still problem with classes...+img

You want something like

RobotDrive *bba = new RobotDrive(1, 2);

There is no class Drive in the WPI libraries (I think).

Re: Still problem with classes...+img

Im trying to creat one....

I succeid to creat a new class but now when im trying to put the code
on the cRio the DS tells me "No Code".

why is that?

here is my code:

MainClass

PHP Code:


		
			
#include "WPILib.h"
#include "Functions.h"
/**
 * This is a demo program showing the use of the RobotBase class.
 * The SimpleRobot class is the base of a robot application that will automatically call your
 * Autonomous and OperatorControl methods at the right time as controlled by the switches on
 * the driver station or the field controls.
 */ 
class RobotDemo : public SimpleRobot
{
    RobotDrive myRobot; // robot drive system
    Joystick stick; // only joystick
    

public:
    RobotDemo(void):
        myRobot(1, 2),    // these must be initialized in the same order
        stick(1)        // as they are declared above.
    {
        GetWatchdog().SetExpiration(100);
    }

    /**
     * Drive left & right motors for 2 seconds then stop
     */
    void Autonomous(void)
    {
        GetWatchdog().SetEnabled(false);
        myRobot.Drive(0.5, 0.0);     // drive forwards half speed
        Wait(2.0);                 //    for 2 seconds
        myRobot.Drive(0.0, 0.0);     // stop robot
    }

    /**
     * Runs the motors with arcade steering. 
     */
    void OperatorControl(void)
    {
        GetWatchdog().SetEnabled(true);
        Functions r;
        
        
        
        
        while (IsOperatorControl())
        {
            GetWatchdog().Feed();
            myRobot.ArcadeDrive(stick); // drive with arcade style (use right stick)
            r.GetSomething();
        }
    }
};

START_ROBOT_CLASS(RobotDemo);

Functions.h:

PHP Code:


		
			
#ifndef FUNCTIONS_H_
#define FUNCTIONS_H_
class Functions
{
public:
    void GetSomething(void);
};
#endif

Functions.cpp:

PHP Code:


		
			
#include "Functions.h"

void GetSomething(void)
{
    
    
}

Re: Still problem with classes...+img

Quote:

PHP Code:


		
			
#include "Functions.h"

void GetSomething(void)
{
    
    
}

That should be:
Functions

PHP Code:


		
			
#include "Functions.h"

void Functions::GetSomething(void)
{
    
    
}

Re: Still problem with classes...+img

Does it compile? It looks like it should work (of course it does nothing).

Try downloading into RAM with the target console window up. Does it print any messages about undefined symbols? When you run it can you see the FRC_RobotTask running (type 'i' to see the running tasks).
