good idea, Rick. I can do that. Also, in the mean time, you can try in
your callback function:
var animationInfo = jmolGetPropertyAsArray("animationInfo")
this provides an array with some valuable elements:
animationInfo.lastFrameDelay=0
animationInfo.firstModelIndex=0
animationInfo.displayModelIndex=0
animationInfo.animationReplayMode=0
animationInfo.animationPaused=false
animationInfo.displayModelName="xxx"
animationInfo.lastModelIndex=12
animationInfo.animationOn=false
animationInfo.animationDirection=1
animationInfo.currentDirection=1
animationInfo.firstFrameDelay=0
animationInfo.animationFps=10
animationInfo.displayModelNumber=1
Note there the two:
animationInfo.animationDirection=1
animationInfo.currentDirection=1
Alas, it is complicated, and I'm not convinced it is bug-free. I think I
just fixed a bug there, but it's hard to say.
Standard animation involves animationDirection = 1 and currentDirection
= 1.
If one sets "anim direction -1", then the animation plays backward, but
currentDirection = 1 still.
Each time you use "anim playrev" the currentDirection switches from 1 to
-1, but animationDirection does not change.
So to know which way an animation is actually running, you have to
consider both these numbers. I think I will put their product into this
variable.
