There are actually quite a few parameters returned by that callback:
function animFrameCallback(app,frame,fileno,modelno,firstno,lastno) {}
Looks like I need to add another indicating WHY the callback was made.
You will also need to know whether this frame was reached by someone
stepping or from a running animation.
Believe it or not, you can do this:
if(_modelNumber = 5);message is5;animframecallback="none";anim off;delay 2;anim
play;animframecallback="testanim";else;message not5;endif
That is, you turn off animation frame callback during the callback, and then
turn it on later!
But I'll be interested in how you solve the problem of someone stepping to the
frame and not suddenly starting to animate. I think you can do it with
variables. But I'll leave you with that challenge, Rick!
