    How to you use values from other function in the same class?

    Code:
    #include "Shapes.h"
    #include "Global.h"
    
    
    #include <iostream>
    #include <SFML/Graphics.hpp>
    
    
    Shapes::Shapes()
    {
        //ctor
    }
    
    
    Shapes::~Shapes()
    {
        //dtor
    }
    
    
    void Shapes::setShapes()
    {
        MainButton1.setSize(sf::Vector2f(100,80));
        MainButton1.setPosition(sf::Vector2f( ScreenWidth/ 10 , ScreenHeight / 4 ));
        MainButton1.scale(2,1);
        MainButton1.setFillColor(sf::Color::White);
        MainButton1.setOutlineColor(sf::Color::Black);
        MainButton1.setOutlineThickness(3);
    
    
        MainButton2.setSize(sf::Vector2f(100,80));
        MainButton2.setPosition(sf::Vector2f( ScreenWidth/ 10 , ScreenHeight / 2.5 ));
        MainButton2.scale(2,1);
        MainButton2.setFillColor(sf::Color::White);
        MainButton2.setOutlineColor(sf::Color::Black);
        MainButton2.setOutlineThickness(3);
    
    
        MainButton1RED.setSize(sf::Vector2f(100,80));
        MainButton1RED.setPosition(sf::Vector2f( ScreenWidth/ 10 , ScreenHeight / 4 ));
        MainButton1RED.scale(2,1);
        MainButton1RED.setFillColor(sf::Color::Yellow);
        MainButton1RED.setOutlineColor(sf::Color::Black);
        MainButton1RED.setOutlineThickness(3);
    
    
        MainButton2RED.setSize(sf::Vector2f(100,80));
        MainButton2RED.setPosition(sf::Vector2f( ScreenWidth/ 10 , ScreenHeight / 2.5 ));
        MainButton2RED.scale(2,1);
        MainButton2RED.setFillColor(sf::Color::Yellow);
        MainButton2RED.setOutlineColor(sf::Color::Black);
        MainButton2RED.setOutlineThickness(3);
    
    
    }
    
    
    void Shapes::ChangeButtonColor( int buttonNum )
    {
        if( buttonNum == 1) // this in main
        {
            buttonCOLOR = 1;
            setButtonColor(buttonCOLOR);
        }
        else if ( buttonNum == 2) // this in main
        {
            buttonCOLOR = 2;
            setButtonColor(buttonCOLOR);
        }
        else if ( buttonNum == 0) // this in main
        {
            buttonCOLOR = 0;
            setButtonColor(buttonCOLOR);
        }
    
    
    }
    
    
    int Shapes::setButtonColor(int buttonColor)
    {
        this->buttonCOLOR = buttonCOLOR;
        return buttonCOLOR;
    }
    
    
    void Shapes::Draw(sf::RenderWindow &VoteApp)
    {
    
    
        if( 0 == buttonCOLOR )
        {
            VoteApp.draw(MainButton1);
            VoteApp.draw(MainButton2);
            std::cout << "should paint the two buttons white" << std::endl;
        }
        else if( 1 == buttonCOLOR)
        {
            VoteApp.draw(MainButton1RED);
            VoteApp.draw(MainButton2);
            std::cout << "should paint the button 1 yellow" << std::endl;
        }
        else if( 2 == buttonCOLOR )
        {
            VoteApp.draw(MainButton2RED);
            VoteApp.draw(MainButton1);
            std::cout << "should paint the button 2 yellow" << std::endl;
        }
    
    
        std::cout << "buttonColor: " << buttonCOLOR << std::endl;
    }
    I don't understand why it print out buttonColor : 72, instead of the value from the Shapes::setButtonColor(int buttonCOLOR) function. How do I make the buttonCOLOR from Shapes::ChangeButtonColor(int buttonNum) to have the same value in the Shapes::raw(sf::RenderWindow &VoteApp) function?

    Code:
    int Shapes::setButtonColor(int buttonColor)
    {
        this->buttonCOLOR = buttonCOLOR;
        return buttonCOLOR;
    }
    Check your capitalization. Your method parameter is never used. Instead you assign your field to the same field

    She was so Blonde, she spent 20 minutes looking at the orange juice can because it said "Concentrate."

    When in doubt, read the FAQ.
    Then ask a smart question.

    I guess I'll just have to put another parameter to all functions and make it work.

    In setButtonColor you passed in an integer named "buttonColor" but don't use it. buttonColor is not the same as buttonCOLOR, but this does seem to be the problem.
