Move layer x pixels every nn frames

[Navarro Parker]

would like to move my layer’s position by an artbitrary amount of pixels in +x direction in a certain period of time.

Ideally, it would go something like this: Every half second, add nn to the x position of a layer using hold interpolation.

Or every 12 frames, jump the position xx pixels to the right.

So there would be a continuous progressive jumpy scroll to the right.

This should work:

tStep = framesToTime(12);
jumpX = 10;
nSteps = Math.floor((time-inPoint)/tStep);
value + [nSteps*jumpX,0]

Hi Dan.
And how about random time and distance intervals ?
And smooth(ease) movement? : )

it would be great if you can add a smooth interpolation between “keyframes” to this expression.

Maybe like this:

tStep = framesToTime(12);
jumpX = 10;
t = time – inPoint;
nSteps = Math.floor(t/tStep);
phase = t-(tStep*nSteps);
e = ease(phase,0,tStep,0,jumpX);
value + [nSteps*jumpX + e,0]

Tnx…. works like a charm. 🙂

That’s sweet. It would be posible to add a pause between those jumps??
Thank you

[Dan Ebberts]

Like this maybe:


tStep = framesToTime(12);
tPause = framesToTime(10);
jumpX = 10;
t = time - inPoint;
nSteps = Math.floor(t/(tStep+tPause));
phase = t-((tStep+tPause)*nSteps);
e = ease(phase,0,tStep,0,jumpX);
value + [nSteps*jumpX + e,0]

It works perfectly!! Thank you very much Dan. Cheers
