OpenGL Texture mapping

take this snippet of my code

Code:

---

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    glLoadIdentity();
   
    glEnable(GL_TEXTURE_2D);
    glTexEnvf(GL_TEXTURE_ENV, GL_TEXTURE_ENV_MODE, GL_DECAL);
    glBindTexture(GL_TEXTURE_2D, texture[0]);
   
    glTranslatef(0.0f,0.0f,-20.0f);
   
    glBegin(GL_QUADS);
        glTexCoord2f(0.0,0.0); glVertex3f(-5.0f,5.0f,0.0f); //BACK
        glTexCoord2f(0.0,1.0); glVertex3f(5.0f,5.0f,0.0f);
        glTexCoord2f(1.0,1.0); glVertex3f(5.0f,-5.0f,0.0f);
        glTexCoord2f(1.0,0.0); glVertex3f(-5.0f,-5.0f,0.0f);
       
        glTexCoord2f(0.0,0.0); glVertex3f(5.0f,5.0f,0.0f); //RIGHT
        glTexCoord2f(0.0,1.0); glVertex3f(5.0f,5.0f,50.0f);
        glTexCoord2f(1.0,1.0); glVertex3f(5.0f,-5.0f,50.0f);
        glTexCoord2f(1.0,0.0); glVertex3f(5.0f,-5.0f,0.0f);
       
        glTexCoord2f(0.0,0.0); glVertex3f(-5.0f,5.0f,50.0f); //LEFT
        glTexCoord2f(0.0,1.0); glVertex3f(5.0f,5.0f,50.0f);
        glTexCoord2f(1.0,1.0); glVertex3f(5.0f,-5.0f,50.0f);
        glTexCoord2f(1.0,0.0); glVertex3f(-5.0f,-5.0f,50.0f); 
       
        glTexCoord2f(0.0,0.0); glVertex3f(-5.0f,5.0f,0.0f); //FRONT
        glTexCoord2f(0.0,1.0); glVertex3f(-5.0f,5.0f,50.0f);
        glTexCoord2f(1.0,1.0); glVertex3f(-5.0f,-5.0f,50.0f);
        glTexCoord2f(1.0,0.0); glVertex3f(-5.0f,-5.0f,0.0f);
    glEnd();

    glBindTexture(GL_TEXTURE_2D, tiles[0]);
    glBegin(GL_QUADS);
        glTexCoord2f(0.0f, 0.0f); glVertex3f(0.0f, 0.0f, 0.0f);
        glTexCoord2f(1.0f, 0.0f); glVertex3f(1.0f,0.0f, 0.0f);
        glTexCoord2f(1.0f, 1.0f); glVertex3f(1.0f, 0.0f, 1.0f);
        glTexCoord2f(0.0f, 1.0f); glVertex3f(0.0f, 0.0f, 1.0f);
    glEnd();
       
    SDL_GL_SwapBuffers();

After I try to change textures and draw my last quad, a blank quad is drawn. I know I'm not changing textures the right way. How do I do it?

Are you sure that tiles[0] is valid and got created successfully? What about if you draw that last quad with the other texture? Does that work?

I suffered pretty much the same problem... I thought it must of been something I had done wrong. Did you get the texture mapping tutorial from NeHe site?

Thanks mr wizard i worked it out.

and no Im reading the opengl red book. much more comprehensive.
