Execute a script on each frame change

[claudevervoort]

Hi!

I wanted to do a simple script to alter an object based on a couple of things (including distance traversed since last frame). The script is simple, but where do I wire it?

That sound easy, but then I dug around, and where I am now is that it seems I should create actually create a command from the script, and modify the playback option to execute that command on each frame change.

Seems more that what I bargained for, so is there another way to do it (in my naive thinking I thought i'd be able to attach the script to the object to be evaluated on each frame change).

(BTW this can easily be done with ICE Kinematics, just this is for a 7.0 release, and also my own exercise to understand a bit more of the scripting in Softimage).

Thanks for any idea!

Not sure, but wouldn't a "scripted operator" be able to do just that?

Thanks Hirazi, I'll look at that and let you know.

That worked for me Turns out you cannot evaluate at another frame from within an operator (which I think makes sense) but I was able to store previous frame data in the UserData which is far more efficient anyway.
