Title: [SOLVED] LoadFromFile Problem
Post by: torenf on November 16, 2013, 07:15:41 pm

Hi guys :D

I will write a little Jump and Run but i have 1 Problem
My Compiler say that sf::sprite dont have the member loadFromFile

Code:

int main()
{
    sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Blockjump");
    sf::Event Event;
    sf::Texture SFigur;
    sf::Sprite PImage;

    if (!PImage.loadFromFile("C:\\Programmiersachen\\sfml test\\bin\\Debug\\Spielfigur.png",sf::IntRect(0, 0, 128, 32)))
    {
    std::cout << "Spieler Image cant load!";
    }

    PImage.setTexture(SFigur);

    while (Window.isOpen())
    {
        while(Window.pollEvent(Event))
        {
            if(Event.type == Event.KeyPressed);
            {
                if(Event.key.code == sf::Keyboard::Escape)
                {
                    Window.close();
                }
            }

        }


        Window.clear(sf::Color(255,255,255));
        Window.draw(PImage);
        Window.display();
    }

return 0;
}

thats the Debugger:

In function 'int main()':|
error: 'class sf::Sprite' has no member named 'loadFromFile'|

sf::Texture does.

Seriously don't guess at how to use a library. Read the official tutorials (http://www.sfml-dev.org/tutorials/2.1/graphics-sprite.php) before posting code that doesn't work.

Your problem is described in the error message, why don't you read it?

error: 'class sf::Sprite' has no member named 'loadFromFile'

As already stated: Read the tutorials in order to know how to use SFML. We like to help with specific questions, but you have to learn the basics first.

For posting code please always use the [ code=cpp ] tag!

Well think, if the image can't be found ...... the application might be looking at the wrong place! ::)
The application will for a relative patch search in its working directory. Some IDEs set them to some other place than the actual binary.

Looks like it is a full path to the file though, in which case I would suggest to check to make sure its actually there and that everything is spelled correctly.

Seriously though, the official tutorials are awesome. They're your best friend.

Ok i can start my Programm but it says still that he cant find the image

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

int main()
{
    sf::RenderWindow Window(sf::VideoMode(800, 600, 32), "Blockjump");
    sf::Event Event;
    sf::Texture SFigur;
    sf::Sprite PImage;

    if (!SFigur.loadFromFile("C:\\Programmiersachen\\sfml\\bin\\Debug\\Spielfigur.png",sf::IntRect(0, 0, 128, 32)))
    {
    std::cout << "Player Image cant load!";
    }

    PImage.setTexture(SFigur);

    while (Window.isOpen())
    {
        while(Window.pollEvent(Event))
        {
            if(Event.type == Event.KeyPressed);
            {
                if(Event.key.code == sf::Keyboard::Escape)
                {
                    Window.close();
                }
            }

        }


        Window.clear(sf::Color(255,255,255));
        Window.draw(PImage);
        Window.display();
    }

return 0;
}

he says in the console unable to open file!

Please help me i put the image into the executable but it dont want ...

Like I said before, make certain that the path to the image you are trying to open is valid and that the file exists there.

The Texture will be able to load the image if that is the case. It wouldn't say it can't find the file for no reason.

Maybe you should try put your image into the directory of your project (near your source like "source.cpp") and write only

if (!SFigur.loadFromFile("Spielfigur.png"))
{
//errore
}

It works by myself..

And you may want to consider using a relative path with "/" not "\\" to have it easier to type and crossplatform.
