i have a problem with this code because the texture is moving all the time but i want to keep it on the place that i declarated in glTranslatef x = 5.0 how should i do it but events have to be in loop this is my code /* Main loop */ finished = 0; while (!finished) { while (SDL_PollEvent(&event)) { switch (event.type) { case SDL_KEYDOWN: if (event.key.keysym.sym == SDLK_ESCAPE){ finished = 1; return 0; } break; } glTranslatef(x, 0.0,0.0); Draw a quad glBegin(GL_QUADS); glTexCoord2i(0, 0); glVertex2i(0, 0); glTexCoord2i(0, 1); glVertex2i(0, 480); glTexCoord2i(1, 1); glVertex2i(640, 480); glTexCoord2i(1, 0); glVertex2i(640, 0); glEnd(); SDL_GL_SwapBuffers(); } }

Ok i got it in main loop i have to do that:

x = 0.0;
that's it

you have to load the identity matrix at the start of each frame with glLoadIdentity.
