Hello! I've recently been really wanting to get into making VGA programs and I wanted to know if some people could give me a few examples of VGA graphical effects. Not routines like 'PutPixel' or anything of that nature, but things that could possibly be used as screen savers like 'Starfield' or something like that. If you could, please keep the examples small. THANKS! Very Happy

P.S. I've already seen the 17 byte demo thread

you could replace the main loop with this

Code:

Main_Loop:
        Wait_VR
     Text_Stuff
  Draw_Flame
  Calc_Flame
        mov     ah,0x01
        int     0x16
        jz      Main_Loop

This will stop it when a key is pressed or for a continue loop replace it with this

Code:

Main_Loop:
        Wait_VR
     Text_Stuff
  Draw_Flame
  Calc_Flame
        jmp     Main_Loop
