Stop loopOut smoothly?
Hi guys!
Once again I need a little help please: I’m trying to stop the loopOut- and wiggle-expressions at a specified time, but smoothly! I don’t want the values to suddenly jump back at the default values from one frame to another when the specified time has been reached!
For the wiggle expression I finally accomplished it with the first code below and animating the amp-slider to zero, when I want the animation to stop. But here too I would be happy about an expression which works without keyframing a slider!
But for the loopOut-thing I’m stuck! The code I’m using right now is the second one below. It works, but the thing I’m using it on is the puppet-tool-position for character-animation and – needless to say – it doesn’t look good, when all the puppet-pins jump back over big distances from one frame to another! What expression can I use, to smoothly move all the puppet-pins to their default values at a specified time, no matter which position-values they have at this time?Many thanks in advance,
Klemensfreq = thisComp.layer("SLIDER CONTROL").effect("Slider Control FREQ")("Slider")
amp = thisComp.layer("SLIDER CONTROL").effect("Slider Control AMP")("Slider")
wiggle(freq, amp)t = thisComp.layer("SLIDER CONTROL").effect("Slider Control TIME")("Slider")
if (time < t)
loopOut()
else

Something like this maybe:
t = thisComp.layer(“SLIDER CONTROL”).effect(“Slider Control TIME”)(“Slider”);
fadeTime = 1;
linear(time,t,t+fadeTime,loopOut(),value)Dan

Works like a charm! Thank you so much!
Just for my understanding, please tell me if I got this right: The linear-expression uses only value1 (in this case loopOut) until tMin is reached, and after tMin is reached it interpolates over the specified fadeTime to value2. Correct?

That’s exactly correct.

Great, thanks again! 🙂
One last short (different) question: Is there a way to apply an expression to many effect controls at the same time rather than pasting it to every single one separately? Like if I have 100 puppet-pins and I want the same expression on every pin – is there any trick I dont know??

For the same property on different layers, you can select the property, the Edit > Copy Expression Only, select all the other layers, and paste.
For puppet pins, you could apply your expression to Puppet Pin 1, and then run a script like this to copy the expression to all the other pins:
{
var myProps = app.project.activeItem.selectedProperties;
var myProp = null;
for (var i = 0; i < myProps.length; i++){
if (myProps[i].name.indexOf('Puppet Pin 1') == 0){
myProp = myProps[i];
break;
}
}
if (myProp != null){
var myExpr = myProp.property("Position").expression;
if (myExpr != ""){
var myDeform = myProp.propertyGroup(1);
var numPins = myDeform.numProperties;
for (var i = 2; i <= numPins; i++){
myDeform.property("Puppet Pin " + i).property("Position").expression = myExpr;
}
}else{
alert("Puppet Pin 1 doesn't have expression.");
}
}else{
alert("Puppet Pin 1 not selected.");
}
}

You are awesome! Thank you!
I’m not in the office anymore, but I’ll definitely try this on Monday!
Btw: I’ve just discovered your website today – I’ll do some further reading there for sure!
Best regards,
Klemens
