General / Re: Class Function not being reckonized.

You should always show the code of what you actually have.

Also there are some spaces right there, not sure if that's intended or just some c&p issue:
sf::Color:: Cyan
void Game:: handlePlayerInput(sf::Keyboard::Key, key bool isPressed)
void Game ::processEvents()

So again, please provide the cleaned up code (in code tags) that generate the error and provide the error message.

First off thank you for taking the time again to reply. I will do a better job in the future of posting the code properly so it isn't so confusing for others. I did figure out the issue. I was incorrectly initializing the function in the game class. Like I said I am learning C++ along side of SFmL. I only have about a 3 month headstart in C++ over SFML. I thought this error I was making was more of an oversight rather than a lack of knowledge (which it looks like it was,) Thanks again for the advice though.

Please use the [code=cpp]// Your Code[/code] when posting code.

The problem is, that handlePlayerInput was not declared in the class itself (there's not void handlePlayerInput(sf::Keyboard::Key, key bool isPressed); directly within the class Game).

If you're unable to solve such a basic problem, it might be best to take a step back and learn some more C++ basics. The SFML Game Development book is not a "How to programming in C++" book, instead it requires quite a bit of C++ knowledge to begin with. If you get a C++ book, make sure to pick a good one.

Thanks for the reply, first off I am learning the C++ language alongside with this, I do have a basic knowledge of language so far I am attempting to learn in tandem. As I said in the list at the bottom I did attempt to declare the function in class game and it still is giving me the same error.

General / Class Function not being reckonized.

I think the subject is the problem at least. This is my code, it is from the book SFML Game Development. I think I am overlooking some simply aspect like a misplace function, but I have tried several things to no avail.

edit:Sorry forgot to mention the compiler error I am getting is "handlePlayerInput( etc...) has not been declared in this scope

Edit 2: I'll leave everything under here as it originally was. The solution that I figured out + based on the opinions of the others below was I was simply declaring the function incorrectly, thanks for those that helped. And to people who are new to SFML what I learned from this is sometimes it is a simple syntax error so be diligent in re-reading your code.

#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>

class Game
{

    public:
                    Game();
      void          run();

    private:
        void        processEvents();
        void        update();
        void        render();
       
    private:
        sf::RenderWindow mWindow;
        sf::CircleShape mPlayer;
};

int main ()
{
    Game game;
    game.run();
}

Game::Game()
: mWindow(sf::VideoMode (640, 480), "SFML APPLICATION")
,mPlayer()
{
    mPlayer.setRadius(40.f);
    mPlayer.setPosition(100.f, 100.f);
    mPlayer.setFillColor(sf::Color:: Cyan);
    }

void Game::run()
{
    while (mWindow.isOpen())
    {
        processEvents();
        update();
        render();
    }
}

void Game ::processEvents()
{
    sf::Event event;
    while (mWindow.pollEvent (event))
    {
        switch (event.type)
        {
        case sf::Event::KeyPressed:
            handlePlayerInput (event.key.code, true);
            break;
        case sf::Event::KeyReleased:
            handlePlayerInput(event.key.code, false);
            break:
        case sf::Event::Closed:
            mWindow.close();
        }
    }
}

void Game::update()
{
    sfVector2f movement (0.f, 0.);
    if (mIsMovingUp)
        movement.y -= 1.f;
    if  (mIsMovingdown)
        movement.y += 1.f;
    if (mIsMovingLeft)
        movement.x -= 1.f;
    if (mIsMovingRight)
        movement.x += 1.f;
}

void Game::render()
{
    mWindow.clear();
    mWindow.draw(mPlayer);
    mWindow.display();
}

void Game:: handlePlayerInput(sf::Keyboard::Key, key bool isPressed)
{
    if (key sf::Keyboard::w)
        mIsMovingUp = isPressed;
    else if (key sf::Keyboard::S)
        mIsMovingDown = isPressed;
    else if (key sf::Keyboard::A)
        mIsMovingLeft = isPressed;
    else if (key sf::Keyboard:: D)
        mIsMovingRight = isPressed;
}

Things I have tried unsuccessfully

• I tried Declaring the handlePlayerInput() before the processEvent() in a void statement
• I tried adding the function to the list in Class Game private.
• I tried to add the handlePlayerIput() into the processEvents()

Thank you for anyone that takes time to help me with this, I feel like it is something simple that I am overlooking. I will continue to work on it on my own, and will edit this if I figure out a solution.
