I need some lightening effects in my game. I don't want to spend hours making a lightening animation for every time I need to use some special FX, so I tried making a lightening algorythm.
I have no idea how to do this, though. It needs to be something like:

Function DrawLightening(x1#,y1#,x2#,y2#,r%,g%,b%)

;...drawing lightening code goes here

End Function

Can anyone help me with this? Or at least just give me some pointers as to how to go about doing this...?
