General / C++ Problem

« on: April 14, 2015, 05:37:55 pm »

After I fixed my linker problems, I stumbled upon another error.

I wrote a code for a small game and I created like a request if-loop to read out the keyboard inputs (Up, Down, Left, Right), and now, to clean up my code I want to put the loop in a seperate function, or even a seperate header file/class.

But I am not able to succeed

First of all: here is my code:

(click to show/hide)

#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
int main()
{
// Create the main window
sf::RenderWindow window(sf::VideoMode(800, 600), "MTGame");
// Load a sprite to display
sf::Texture texture;
if (!texture.loadFromFile("./data/test.jpg"))
return EXIT_FAILURE;
sf::Sprite sprite(texture);

// Load a music to play
sf::Music music;
if (!music.openFromFile("./data/background.wav"))
return EXIT_FAILURE;
// Play the music
music.play();


// Start the game loop
while (window.isOpen())
{
// Process events
sf::Event event;
while (window.pollEvent(event))
{
// Close window -> exit
if (event.type == sf::Event::Closed)

window.close();
}
//Move-Loop
if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
{
    sprite.move(-1, 0);
} else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
{
    sprite.move(1, 0);
} else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
{
    sprite.move(0, 1);
} else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
{
    sprite.move(0, -1);
}
//End-Loop

// Clear screen
window.clear();

// Draw the sprite
window.draw(sprite);

// Update the window
window.display();
}
return EXIT_SUCCESS;
}
 

The section //Move-Loop is the part I want to put in a seperate function.

So basically I just have to declare a function with a sf::Sprite as parameter which then represents the sprite that is supposed to get moved...

(click to show/hide)

. . .
void mover(sf::Sprite temp) {
       if (sf::Keyboard::isKeyPressed(sf::Keyboard::Left))
       {
           temp.move(-1, 0);
       } else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Right))
       {
           temp.move(1, 0);
       } else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Down))
       {
           temp.move(0, 1);
       } else if (sf::Keyboard::isKeyPressed(sf::Keyboard::Up))
       {
          temp.move(0, -1);
       }
 

But that does not work...
I am kinda new to C++ (as you can see ) but was pretty stable with coding until this point.

So could anyone please help me.
Best with a working solution with outsourced classes (in a header file).


Thank you for your help in advance...

(I don't know if this is the right place to post this stuff. If not please tell me where to put it and I will copy it there and delete this post)

Got it to work....

I had the dependencies setted wrong.

If anyone should have problems with it, here is a picture of the finished order.
Note: I used the "extlib" included on the github directory.....

Thank you all so much for helping. It is working perfectly for me now

Ok....
I moved all the modules to the top...
So sfml-system-s and co. to the top of the list and then the dependencies...

This got rid of the

C:\SFML-2.2\lib\libsfml-system-s.a(SleepImpl.cpp.obj):SleepImpl.cpp   ||   undefined reference to `_imp__timeGetDevCaps@8'|
C:\SFML-2.2\lib\libsfml-system-s.a(SleepImpl.cpp.obj):SleepImpl.cpp   ||   undefined reference to `_imp__timeBeginPeriod@4'|
C:\SFML-2.2\lib\libsfml-system-s.a(SleepImpl.cpp.obj):SleepImpl.cpp   ||   undefined reference to `_imp__timeEndPeriod@4'|

error, but instead I now have an

||=== Build: Debug in MTG (compiler: GNU GCC Compiler) ===|

error...
I'm completely stuck now

Look at the tutorial, the way it's listed there is an order that works.

It usually is if x depends on y then x comes before y.

I understood it. I now moved all the main module (sfml-system-s(-d) and so on) and let the dependencies stay at the top. It changed like nothing...

||=== Build failed: 5 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

But I recognised that in the error log there is a file that is located on my D:\\ drive:

D:\sfml-release\_Sources\SFML\src\SFML\System\Win32\SleepImpl.cpp

But I didn't find the folder/directory. The dir "D:\sfml-release\" is not existent on my PC?!

Is that supposed to happen or am I missing some files?!


Also: Which order it's listed??
The table that lists the needed dependencies?! Because otherwise there is just the dynamic linking shown-

Thanks for the reply ^^

To me it looks like he declared the libs in a wrong order.

So how is the right linking order. ^^

Thanks for your replies though

General / [Solved] Undefined reference [Static Linking]

« on: April 13, 2015, 06:57:08 pm »

I fixed it, look down below for my working linking order....


---------------
Hey there

I am using SFML for quite a while now, but just used dynamic linking.

Now I decided to set up static linking.

But every time I try to compile something, I get a few errors...

I think I did set up the project properly...

(click to show/hide)

(click to show/hide)

(click to show/hide)

I also added the "SFML_STATIC" to the #defines...

The code is:

(click to show/hide)

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}
 

That's the error message:
 

(click to show/hide)

||=== Build: Debug in MTG (compiler: GNU GCC Compiler) ===|

I hope that somebody can help me.

Thanks in advance
