Whats a good way to do page flipping with allegro? Most of my attempts make the program go way way way slower than it previously did. I don't know if that's unavoidable, or if I'm doing it wrong. I did it something like this before: void page_flip() { show_video_bitmap(screen2); // thats the screen i would write everything onto // would this function copy screen2 to screen, or // would it change the viewport to screen2? } void main() { // set the gfx mode to 320, 240 view, 320, 480 virtual size while(!gameover) { drawstuff(); page_flip(); } } Thanks, Al [muaddib AT proaxis DOT com]
