Graphics / Re: Problem with a Drawable splash to draw to window [SOLVED]

I'll admit that my math isn't the best , but it wasn't my math this time....LOL When you refactored the code you placed the sprite to set the texture before the block of code to loadfromfile, so the constructor was trying to set the texture that wasn't even loaded yet. Once I placed setTexture after that block of code, it appeared. Thanks for your help.

Ok so I created the files and tried to compile and during linking I got some errors.

main.o: In function `main':
main.cpp:(.text+0xb6): undefined reference to `Splash::Splash()'
main.o: In function `Splash::~Splash()':
main.cpp:(.text._ZN6SplashD2Ev[_ZN6SplashD5Ev]+0xe): undefined reference to `vtable for Splash'
collect2: error: ld returned 1 exit status

Here are the commands that I used:
g++ -c main.cpp
g++ main.o -o Main -lsfml-graphics -lsfml-window -lsfml-system -lglut -lGLU -lGL -lXmu -lX11

That is some old code that I was playing around before all this. I've deleted that code already after posting the last posting. Thanks for the comments, I'll surely take a look at what you changed.

Thank you eXpl0it3r for all the comments about my code. They really helped me correct my code and got it working. I'm just getting my hands wet on programming with graphics. I'm still in school and next semester is my first OOP class which will cover most of the items you listed in your comments. Since I'm a nice person and there isn't much resources on the web that gives full code on creating a drawable class in a .h file and the main.cpp file. I'll share the full code in hopes that someone else will find it useful. This code does work and was compiled and tested running Arch Linux.

Graphics / Problem with a Drawable splash to draw to window [SOLVED]

« on: July 03, 2015, 11:34:56 pm »

Hi everyone, hopefully this is the right area for this post.
Could someone take a look at my code and see why the splash will not show in the window? I'm not getting any errors, it just won't show in the window. I've read the example from the docs, some other problems like what I'm trying to do but I'm stilling having some problems. Thanks for any help.

Code from splash.h

#ifndef SPLASH_H
#define SPLASH_H

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

class Splash : public sf::Drawable
{
   
    private :

    sf::Sprite m_sprite;

        virtual void draw(sf::RenderTarget& target, sf::RenderStates states) const
        {
            target.draw(m_sprite, states);
        }

    public:
        Splash();
};

Splash::Splash()
{
    std::cout << "Entered default constructor" << std::endl;
    sf::Texture m_texture;
        m_texture.loadFromFile("resources/Splash.png");
    sf::RectangleShape m_rectangleShape;
        m_rectangleShape.setTexture(&m_texture);
    sf::Sprite m_sprite(m_texture);
        m_sprite.setTextureRect(sf::IntRect(0, 0, 300, 300));
        m_sprite.setPosition(0,0);
}
