Graphics / Sprite tearing problem?

« on: November 30, 2013, 06:23:42 am »

This is what's happening when I load certain sprites. Is it just that they're too big? Is this a known problem with SFML?

Here is my code (It's long) Tell me if posting the sprite map we're using would help (I load the charizard sprite under the function EVOLVE(); )

#include "stdafx.h"
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>

Ooooh, I got it, Thanks so much, That should work.

                TIMER.restart();
                Time t1 = TIMER.getElapsedTime();

t1 is probably 0ms or close to 0ms.
So it is never >= milliseconds(333) or >= t2 (which is also milliseconds(333) lol.).

When posting pieces of code (especially long ones) in the forum, you have to surround it with code tags. It greatly improves readability and you'll be more likely to get answers.

Thanks, I changed it.

Doesn't getElapsedTime get the time of how long the program has been running so far? So wouldn't it never be 0ms?

So I made this program and I totally was able to grab sprites until I added code for animation. All of the sudden when I run it, it's not showing anything. Here is the code. Why doesn't it work?

#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
//#include "Chardicks.h"
//#include "Keystrokes.h"

using namespace sf;
using namespace std;

Texture texture;
Sprite Charmander;

int main()
{
    RenderWindow window(VideoMode(640, 480), "FUCKING CHARMANDER!");

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

                Clock TIMER;
                TIMER.restart();
                Time t2 = milliseconds(333);
                Time t1 = TIMER.getElapsedTime();
                int step = 0;

                TIMER.restart();

                if (t1 >= milliseconds(333))
                {
                        window.clear();
                        texture.loadFromFile("PokeSprites.png", IntRect(1,1,32,32));
                        Charmander.setTexture(texture);
                        step = 1;
                        TIMER.restart();
                        window.draw(Charmander);
                        window.display();

                }
                if (t1 >= t2)
                {
                        window.clear();
                        texture.loadFromFile("PokeSprites.png", IntRect(0,32,32,32));
                        Charmander.setTexture(texture);
                        step = 0;
                        TIMER.restart();
                        window.draw(Charmander);
                        window.display();
                }

General / My window will only stay open for a second.

« on: November 12, 2012, 06:08:37 am »

I am very new to the SFML libraries, I have been reading through the tutorials and decided to play around with it to see how it worked. Everything was working fantastically! I fixed my linker issues, Everything was running smoothly...

Until I Cleared the screen and drew a shape.
After I put in those two instructions the window now only stays open for a second then closes.

I am using SFML 1.6 with Windows Visual C++ 2008 Express edition.

Here is the code

#include "stdafx.h"
#include <iostream>
#include <SFML/Graphics.hpp>
#include <SFML/Window.hpp>
using namespace sf;
using namespace std;

int main(){


RenderWindow App(VideoMode(800,600,32), "Tutorial");
Shape rect = Shape::Rectangle (0, 0, 10, 10, Color::Red);
int NumberLoops = 0;
while(true) {
Event handle;

while(App.GetEvent(handle))
{
       

       
        cout << "Next loop has been made, It has looped" << NumberLoops << "times";
        NumberLoops++;
        cout << endl;
        if(handle.Key.Code == Key::Back || handle.Type == Event::Closed) {
                App.Close();
        cout << "Window closed";
        cout << endl;
        }
        if(handle.Type == Event::MouseButtonPressed) {
                cout << "Mouse button pressed?";
                cout << endl;
        }
       
        if(handle.Type == Event::MouseButtonReleased) {
                cout << "Mouse button released";
                cout << endl;
        }
}
App.Clear();
App.Draw(rect);
App.Display();
}


return EXIT_SUCCESS;
}

If I get rid of App.Clear(); and App.Draw(rect); It will run fine without closing, But apparently those two members of the RenderWindow class doesn't like my IDE very much.

Where have I gone wrong?

If it helps anything, this is what it says on the debug window when it closes.

Please read the tutorial carefully. Look at the screenshots.

I found my solution, for some odd reason I was putting .dll instead of .lib

Thank you so much for being patient with me and showing me where I needed to be.

It is explained in the "Getting started" tutorial.

Alright cool, So I went into additional dependencies and put in  sfml-graphics; sfml-window

But when I tried to run it, it gave me this fatal error.

1>LINK : fatal error LNK1104: cannot open file 'sfml-graphics;.obj'

You must link to sfml-graphics and sfml-window.

Oh thank you! A reply

How do I link? D:

I am using Micrsoft visual studios C++ 2008

I opened a C++ console window after installing and following all the directions for install and including all the libraries for the project.

This is the code

#include "stdafx.h"


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


int main() {

        sf::RenderWindow Game(sf::VideoMode (800, 600, 32), "SFML window test" );
                sf::Event Event;
                while(Game.IsOpened())
                {
                        while(Game.GetEvent(Event)) {

                                if ( Event.Type == sf::Event::Closed)
                                        Game.Close();

                        }
                        Game.Clear();

                        Game.Display();

                }
        return EXIT_SUCCESS;
}
