Thanks Jason. It’s a great op you’ve created, so it’s worth bullet-proofing.

Turns out there’s an elegantly simple self-referential solution: Find your tween in self.TweenItems and set theTween[5] = 0, forcing the endTime to less than current time, thus naturally ending the tween onFrameStart while continuing any chaining via onComplete.

So far, this seems to meet the need for me.

perfect! Likely how I would have solved it as well.

Hey @amazingrobot,
First, thank you for the TOX! It has been very helpful for multiple projects.

I made some adjustments to fix a few issues:
Tweener_v1.3.4.tox (17.3 KB)

Adjustments :

  • _path_trace issue : Fixed the 1.2 op path error by correcting the _path_trace method (as @horristic suggested) and adding aroot exception (the issue @Achim mentioned). This was done by modifying path = '/'.join(path) to path = '/'.join(path) or '/' to handle empty paths correctly.

  • op reference inside the comp : Replaced global shortcuts with parent shortcuts for op references. This allows multiple Tweener comps (e.g., if implemented in different TOX files) to coexist in the same project without conflicts.

  • Error on a running tween for a removed op: In my project, some tweens were running on comps created by a replicate comp, which could disappear at any time. Even though I was killing the tween when the comp disappeared, errors could still occur due to sync issues. To fix this, I added a check every frame to verify if the operator still exists before executing the tween command. If it doesn’t, the specific tween is killed.

  • Tween Items Table: Added a DAT table displaying all running tweens from the TweenItems list.

Next Adjustments I want to make :

  • Improve the TweenItems Visualizer: Add a List COMP to enhance the UI, along with a “Kill Tween” button and a button to jump to the specific operator, similar to Matthew Ragan’s Base Save tox

  • Kill previous tween when a new one modifies the same parameter on the same operator.

Wow, Thanks so much for putting the time in to improve this! I will get your changes and notes added to the page. I have been meaning to get this added to github. When I get that done I give you access.
