Shape Tweening Issues with Spirograph

New Here ,

Hello there! For starters: I use Adobe Animate 2019 CC! 

 

Beyond that, however, I've been having issues with shape tweening. Using copy and pasting of a curve, I've had it so that when I move one segment of this curve, it moves it's other segments, to give the illusion of a moving spirograph that's changing shape constantly. However-- the big issue I've had is that when this is moving, a bunch of random lines suddenly appear between points? And then vanish as soon as the tween reaches the last keyframe.

 

I've got no idea how to fix this. Included below are snapshots of the issue, as well as my project file. So hopefully this can help anyone figure out what the problem is. 

 

Forgive any slop within' the file- I'm a newcomer and still trying to learn the tricks of this program. Many thanks to any who help!

And for the project itself.

Welcome to the very unpredictable world of Shape Tweening in Animate! For decades, the shape tweening tools has been very unpredicatble and unfortunately, very ignored. It has never received an update or an improvement. It's finicky and the simpler the vectors, the better chance of success. But I've seen epic failures with just 2 point segments. 

In your case, you may need to simply address this animation in a different way. Hard to suggest a technique without seeing your intended animation/motion. Do you want it to simply retain the design as you have it in frame 125 of your document?

It would be awesome if we could choose more algorithms for shape tweening or even create our owns.

I was originally hoping to have the spirograph, throughout this animation, morph into about 8 different patterns, including the base one as seen within' Frame 125 of the Document. Of course this seems to be much easier said then actually done.

 

I purused the fourms earlier before making this post, just to make sure my question hadn't been asked and answered before, and it seems like Shape Tweening certainly has an extensive history around here for it's overwhelming multitude of jank. I may attempt to ultimately approach my spirograph in a different manner. I'll see if I can come up with anything in the meantime before whenever your next reply is.

This is a tough one. Have you tried shape hints?

I have, indeed, tried! And much to my glee, they seem to just as well mess up the lines even moreso then they were originally messed up. I suppose there was a certain naivete in believing this would be a simple fix, unfortunately.

 

Thank you for the reply!

the only way to "tween" that in animate is with code.  it's just way to complex for timeline tweening.

I don't really know code- so I may be out of luck here.

it's actually easier (but still not easy) to create your own spirographs in animate with code.  they could then be more easily tweened (with code).  but that wouldn't be easy, either.  here's a sample:

p.s. on my landing page, i have an js spirograph, https://www.kglad.com/

This is very kind of you, and I'll be sure to take a look later: but my main problem os that I just don't really know HOW to code. I'm an Artist who doesn't really understand the first thing about coding, haha.

 

I'll puruse it later and see if I cna discern anything that can help me, but I think for the time being this route may be infeasible for me to go down.

this is not a suitable project to start learning to code.
