Duplicate Frames

I've been doing animation timing on some sprites by using duplicate frames (to keep time with other sprite animations). Now I believe those duplicate frames are using up resources. I've tried changing the timing to code based, but can't get it working as well. Is there a way to link duplicate frames?

Not a huge thing, but I'm trying to keep the size of the game as small as possible.

Did you know you can change the Frame Speed for each individual frame in an animation?

I did. Unfortunately I have other things depending on frame changes of the animation. If there's only one frame that waits, it doesn't count as a frame change.

I see. Is there any way to have an invisible timer sprite that runs a simple 1-frame animation so as to trigger those events?

Not sure. How would I make that work with the on frame changed condition? I tried changing it to an "every x seconds" condition and linking it to the on touched trigger, but it only changes the opacity once (when touched).

These events need a constantly changing condition. On frame changed is the only one I can find.
