View Full Version : Blink eye random animation
05-04-2003, 12:57 AM
I've a great idea. I've two blend shapes one with the eyes opened, another one with the eyes closed.
With an expression, I want randomly make the eye closed during 5 frames... And then reopen the eyes (sure)!
How to make randomly set the closed eyes blend shape to 1 during some frames (here is my pb)!

sorry.. unless this is for background characters, having random blinks on your guys is definitely the wrong way to go. Blinking adds SO much to a character.. I can't imagine not wanting to animate this by hand.
BUT.. if you're desparate.. you can make the expression a sin wave or something like that..
$currentState = lefteye.blink;
global int $startFrame;
if ($currentState == 0)
// the eye is open.. do a random value check and see if we should start closing it.
$rand = rand(0,1);
if ($rand >= .9)
// time to start closing the eye.. set the startframe
$startFrame = frame;
lefteye.blink = .1;
// we're in a blink now
$currentFrame = frame;
// this is super sloppy.. you can make it much better..
$frameDif = $currentFrame - $startFrame;
if ($frameDif == 1)
lefteye.blink = .4;
if ($frameDif == 2)
lefteyeBlink = 1;
if ($frameDif == 3)
lefteyeBlink = .9;
if ($frameDif == 4)
lefteyeBlink = .5;
if ($frameDif == 5)
lefteyeBlink = .1;
if ($frameDif == 6)
lefteyeBlink = 0;
haven't actually checked to see if it'd work, but give it a shot.. ya never know. :)

Oh thanks :beer: I will study it!
Sorry for my english. The word "blink" means for me "refresh eyes". Sure, I don't want use script to animate a one eye blink :)
