How to make SYMBOLS loop forever without

duplicating frames… yea in adobe animate you just make 3 frames of animations and automatically they loop… BUT NOT in TB…you have to manually make MORE FRAMES to cover that…

how can I loop it without duplicating?

Harmony 21 Premium now has Timing Nodes under the Node Library.
What you are looking for is the Loop Node.

If you are using a older version of Harmony you can paste cycles.

Sure!

But, nevertheless, I would love if one day I could say to a client:
Ok, you insiste on using Flash/Animate because you’re used to work with symbols?
No problem, we can do the same thing in Harmony because Harmony’s symbols now also got “Play Once” and “Play Loop” play modes. :wink:
