First I started off by attaching the blink animation to the end of each of the idle animations & then I edited the first frame of each of the idle animations & created an execute a script action part containing...
if math.random(20) < 13 then
ActiveAnimations["animation_name"].AnimationLastFrame = 16
else
ActiveAnimations["animation_name"].AnimationLastFrame = 21
end"animation_name" would be the name of the animation (I added a generic name to the code block). Also the number values are the amount of frames of the animation without & with the blink part of the animation. In this case frames 1-16 were the idle part of the animation & frames 17-21 was the blink part.
The little script above randomly generates a number between 1 & 20 & if the number is less than 13 then it will only play the idle part of the animation but if it equals 13 or more then it will play the idle part of the animation & then the blink part of the animation. This means that there is a 7 out of 20 chance that the character will blink at the end of the idle animations loop cycle.
In Visionaire Studio we can force which animation frames of an animation can be played by defining the initial & end frame using AnimationFirstFrame & AnimationLastFrame.
Pretty straightforward, no?
