SteppedEase - Hold & Step

Go to solution Solved by mikel,

Recommended Posts

I am trying animate a SVG element where the element's position/pose is held for a duration and then snaps immediately to a new position/pose, and so on and so on.

 

I have a working example using SteppedEase, but it feels a bit hacky - as it requires me to use an undocumented 'true' parameter (mentioned in: https://greensock.com/forums/topic/13388-steppedease-to-step-immediately) and duplicate the relevant SVG element's path data from the inline SVG image - with a slight modification (otherwise the duplicated path seems to be ignored).

 

In the codepen example - the Red square should snap to align with the Green triangle as it passes the little blue squares (at 0s, 1s and 2s).

 

When I tried using just steps(1) - it stepped once, but at 50% of the inter-blue-square duration (1s in this example). Whereas I need it to step once at 100% of that duration. So the overall behaviour would be more akin to using a series of Hold durations.

Excellent (once again). Looks like I just had to get out of my tunnel thinking, essentially swapping out: Steps with n Duration & zero Delay, for: Tweens with n Delay & zero Duration.

 

And I guess - when I stop and think about it... a 'Hold duration' is a 'Delay'! 😄

 

 duration: 0, delay: 1

 

Regarding "Normal Transforms" - This was a simplified explanatory example. Back in the real world, the transitions will be various state changes - which could be Transforms, Styling or Deformations of SVG data elements, with more complex timelines and various interpolation combinations.

My updated version ...

Thanks again.

Hey Sam. If I were tasked with this sort of thing I might try using the onUpdate of the triangle's animation to update the position of the square when necessary. But the approach that you now have works as well, though I recommend using .set() instead of .to() if you have a duration of 0. I also recommend using the position parameter instead of delay. 

 

P.S. When making new versions of your demos for these forums can you please try to remember to use the "fork" button? That way context is not lost when you update your code.

Hi Zach. There is no relation between the triangle and the square per se. The triangle is just there, for this example, as a visual timeline playhead position indicator.

 

I will update to code to use Set (as it makes sense).

With regards to Position. I would happily use it, as again - it would make sense, but I don't think I can as I am using keyframes, and I canny find anywhere to place the 'position' parameter for each sub-tween. i.e. Where would the 2 keyframed sub-tween's position parameters go in the below example snippet?

 

tl.set('#FL0S1_sqr', {keyframes: [
  {x: '563', y: '0', duration: 0, delay: 1},     
  {x: '1126', y: '0', duration: 0, delay: 1}, 
]}, 0);


Also... I definitely forked my original pen. I have double checked and can see it listed as such on the details page.

Cheers

Ah, I didn't notice. If you're using keyframes then you're correct to use delay.

You're also correct here. I apologize for my hastiness :)
