        glDisable( GL_DEPTH_TEST );
        
        for(int j = 0; j < 25; j++)
        {
            //xcord,ycord,zcord are coordinates to give to the function, for the moment 
            //i use the center of the screen..
            glRasterPos3d(--xcord,--ycord,zcord);
            for (unsigned int i = 0; i < texte.size(); i++)
            {
                glutBitmapCharacter( GLUT_BITMAP_HELVETICA_12, texte* );
            }
            compteur.dormir(1);

            //glClear(GL_COLOR_BUFFER_BIT);
        }
