Wiggle expression. Precise time to start and stop

[Dan Ebberts]

Like this, maybe:

timeToStart = 2;
frameToStart = 12;
timeToStop = 4;
frameToStop = 12;

d = thisComp.frameDuration;
if ((time > (timeToStart + frameToStart*d)) && (time < (timeToStop + frameToStop*d))){ wiggle(3,25); }else{ value; }

Hi Dan,
don’t you think it is possible to link the wiggle expression to a slider, and then to put keyframes when it should start and finish ?

[Benoit Bouchard]

Finally, that’s the way I did it.

Expression Control Slider is the way to go for sure. Will give you ability to switch on the shake at any instance on the timeline, with variable value of shake as well as a smoother reposition after the shake

I’ve found that decimals work.

timeToStart = 2.25
timeToStop = 4.5

if ((time > timeToStart) && (time < timeToStop)){
wiggle(3,25);
}else{
value;
}

How can I connect the wiggle expression to the slider?

Thanks

Enter your expression in the desired field such as position, but instead of entering values (such as “wiggle(0.2,1)”, ‘pickwhip’ each of the values to a Slider Control Effect placed on either the same layer or another layer. Usually you’ll have 2 Slider Controls, for Wiggle Rate and Wiggle Intensity.

You’ll end up with something like:

wiggle([slider 1 name],[slider 2 name])

Hi,

I like to add few more wiggles at different times. How can I achieve that?

What am I doing wrong down there

timeToStart = 2;
timeToStop = 2.5;
timeToStartOne = 5;
timeToStopOne = 5.5;

if ((time > timeToStart) && (time &lt; timeToStop)){
wiggle(12,80);
}else{
value;
}

if ((time > timeToStartOne) && (time < timeToStopOne)){
wiggle(12,80);
}else{
value;
}

[Dan Ebberts]

Try it this way:


timeToStart = 2;
timeToStop = 2.5;
timeToStartOne = 5;
timeToStopOne = 5.5;

if ((time > timeToStart) && (time < timeToStop)){
wiggle(12,80);
}else if ((time > timeToStartOne) && (time < timeToStopOne)){
wiggle(12,80);
}else{
value;
}
