Copy an objects key-frame value through max script?

[jeffpanek3d]

I have a chain of helper objects parented together, with their own rotational values. And I'd like to  copy/paste a helper objects' key-frame value at one position in the timeline and paste to a new position. As an example to copy the key-frame for "Dummy1" at frame 5 and paste this at frame 20.

Ive spent several hours collating with ChatGpt, which yielded disastrous results.

There are many solutions, all of which can do something similar to what you need... but the right one is:

with animate on at time 20 
(
	$dummy1.rotation.controller.value = at time 5 $dummy1.rotation.controller.value  
)

The code above shows how to retrieve a value from a specific time and apply it to another time. However, if you are asking about key operations or how to organize the UI for it, that's a different story.

because it's not charging for the extra time yet 😉

"copy/paste" sounds like your are looking for an interactive function in the GUI? If so, you can do that with Shift-moving keys, either in Trackview or in the timeline.

If you want to do it via MAXScript, you need to look at the objects controllers, for example  $Sphere001.position.controller.keys is an array of keys.
