Per Character Bounce Scale

[Dan Ebberts]

Did you just want a delay that increases for each character? That would look like this:


delay = .1;
myDelay = delay*textIndex;
t = (time - inPoint) - myDelay;
if (t >= 0){
freq =3;
amplitude = -100;
decay = 1.0;
s = amplitude*Math.cos(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]
}else{
value
}

Superb! Thanks Dan.

Great expressions Dan!

I’ve been tweaking the expression to attempt to get a “Back” sort of animation where a word starts at 0, overshoots it’s scale, then settles back at it’s regular size. Would there be a way to tweak the expression so that it only does the one motion and stops bouncing?

I’d say start with something like this:


delay = .1;
myDelay = delay*textIndex;
t = (time - inPoint) - myDelay;
if (t >= 0){
freq =2;
amplitude = -200;
decay = 15;
s = amplitude*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
[s,s]
}else{
value
}

Thanks Dan, this is a great place to start. I think I can tweak it from here!

Much appreciated.

Hi, i have a question about. I used it for “animate in” a word and it works, is there a way to “animate out”? I tried but maybe i don’t know what is the parameter to set.

Thanks

You have to duplicate the entire animator and then all you need to do is change the the “t” variable from:”t = (time – inPoint) – myDelay;”
to “t = (outPoint – myDelay) – time;”.

Hope it helped! 😛

I’ve tried applying the expression as mentioned above and am getting no action what so ever. I have attached a screen grab of the simple set up as described. What have I missed in setting this up?

Thanks,

Chad

For scale, I think you’d want something more like the second expression in the Calculation Overshoot section of this article:

This string has been an amazing help. So, two things.

First, thank you very much. I’m waaaaay closer now than I was when I started, all thanks to you.

Second, in the digging I’ve done around these here internets, to use an expression with text animators, you’re pretty much getting rid of the range selector. I’m curious to know if there’s a way to have the best of both worlds?

In short, I’m matching the words up with what is being said by a voiceover, so I’d love to be able to get in there and tweak the timing for “per word bounce out” alignment.

Think William Shatner as Captain Kirk delivering a line. Is there a way to easily align the triggers for each word’s bounce out animation to align with when it’s being said?
