Reverse a Morph and then fluidly repeat from the start

Recommended Posts

Hi,

 

I'm doing a simple morph that repeats between two shapes (with a rotation on as well).  When the animation runs, it morphs, then seems to pause for 3 seconds, then seems to do a fluid repeat morph between the two states (which is what I want), and then starts again?

 

How do I get a morph to fluidly go from one shape to another on repeat with out the pause.  I'm using yoyo: true as well and thought this would solve it?

 

I'm flummoxed.

 

var tl = new TimelineMax({repeat: -1, yoyo: true});

tl
.to("#shape-1", 3, {morphSVG:"#shape-2", rotation: 180, ease: Power1.easeIn})
.to("#shape-2", 3, {morphSVG:"#shape-1", rotation: 180,ease: Power1.easeOut})

 

Many thanks,

Hi @pauljohnknight :)

 

That three second delay is your second tween:

.to("#shape-2", 3, {morphSVG:"#shape-1", rotation: 180,ease: Power1.easeOut})

 

That morph is happening but #shape-2 is hidden so you see nothing. If I understand your desired outcome correctly, you only need the first tween on the timeline.

Is that what you meant?

Thanks for both answers

The problem was being caused by my second tween - I didn't realise when returning to the original svg shape with MorphSVG that you need to reference it in both parts of the tween.  Shaun's tip of having the rotation outside of the morphing was very useful as well.

Thanks again

 

Paul.

For a seamless rotation you can also set that rotation ease to Linear.easeNone

Happy tweening.

Hi Craig,

 

Yes i did end up doing that actually when I was playing around with the easings. 

In relation to this, I've used a Sine ease with an easeIn and easeOut to try and get the morph as smooth as possible on each of the two morph tweens.  I guess there will always be a slight jerk effect because the morph has to stop and restart? Even if I was to use the custom ease plugin?

 

Updated pen for quick reference.

Are you looking for more of a smooth pulse here? If that's the case, I think a Sine.easeInOut would probably work well. Here's a fork of your pen:

I commented out the rotation and cranked the timeScale up to 10 so it's easy to see what's happening. Is that more the look you wanted?

 

Happy tweening.

:)
