How can i make the circle loop nicely?

[Triable]

I'm making an animation that pulses and has a circle that grow. I got the pulse and growing, but I can't seem to make it loop nicely. Anyone got any ideas?

I have a reference video, but it is to big to upload unfortunately.

 

Thanks in advance

 

Edit: codepen is changed to the finished animation

Hey Triable, welcome to the GreenSock forums!

 

A video would be incredibly helpful. Maybe you could host it on YouTube unlisted and share the link with us? It's not clear what you want to happen, especially with the red ring.

Great idea!

Doing rings like that is actually not a very trivial thing in the DOM. Since outside clip paths don't exist with DOM elements, to do that with DOM elements properly you should use a clever clip path trick. That's what I used in this pen. However, animating clip paths is not very performant. Other hacky ways may exist depending on your exact use case.

 

I'd recommend doing this in Canvas. With Canvas it's much more trivial to create rings using the arc command. It's probably best to make a more abstract ring object whose values you can then animate.

Hi @Triable, indeed welcome to GreenSock and the forums.

 

Here is an older thread with pulsing circles

 

 

Or many others which are relative can be found also in the link below, maybe something will help you.

If you want to make it work with SVG you could do something like this:

Hopefully that helps. Happy tweening.

Doh, I forgot about strokes  Good work.

just a variation of the concept of @PointC: with 'special ease'
