Graphics / A weird message when loading a file to Texture !

« on: June 16, 2013, 03:16:06 pm »

Here's my code :

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

int main(void) {
        sf::RenderWindow Window;
        Window.create(sf::VideoMode(640, 480), "First app", sf::Style::Titlebar | sf::Style::Close);

        sf::Texture pTexture;
        sf::Sprite playerImage;

        pTexture.loadFromFile("player.png");
        playerImage.setTexture(pTexture);

        while(Window.isOpen()) {
                sf::Event Event;
                while(Window.pollEvent(Event)) {
                        switch(Event.type) {
                                case sf::Event::Closed :
                                        Window.close();
                                        break;                 
                        }
                }

                Window.draw(playerImage);
                Window.display();
        }
}

And here's the message that come on the console window :

An internal OpenGL call failed in Texture.cpp <146> : GL_INVALID_ENUM, an unacceptable
value has been specified for an enumerated argument
An internal OpenGL call failed in Texture.cpp <147> : GL_INVALID_ENUM, an

Graphics / My game run really slow when using sf::Text ? : (

« on: August 02, 2012, 01:35:08 pm »

Hello,

I'm using SFML 2.0.

I only have three instances of the Text class :

sf::Text heroText("Get of my face ... ");
sf::Text instText("Press 'Space' to speak with people, 'Z' or 'X' to rotate \n and arrows to move");
sf::Text anonyText("?");
 

However, when I draw those instances like this :

window.draw(heroText);
window.draw(instText);
window.draw(anonyText);
 

the program at first run slow, but then after like 15 seconds it return to it's normal speed.
So why when I remove the window.draw functions it run at normal speed , but when I use them it run slow at first ?
