If you’re emulating the light flicker from a candle using a solid color and adjusting its opacity, the wiggle expression is perfect for replicating the sporadic nature of a flickering flame. This is a lot faster than tediously animating the media item back and forth, or continually lowering the opacity or scale.Īs noted in the examples above, although the wiggle expression is usually applied to an object’s position, there are numerous applications for the wiggle expression. With that covered, what about in the case of the wiggle expression? With a wiggle, we’re instructing the property, whether the scale, opacity, or position, to wiggle within the set parameters. An example of a script-not an expression. For example, this script tells the application (the application being After Effects) to position the anchor point of this layer to the center, the right, or the top. Now, unlike a script, which tells the application to do something, an expression will inform the individual property to do something.

So my question is: how do I make it so the wiggle expression only starts after the ease and whizz has ended? I know the wiggle expression accepts time values, but honestly I've never done anything that complex.First, before we look at what the wiggle expression does, we must ask: What is an expression? An expression is a piece of JavaScript code that you can insert into the animated properties of your media.

This is from the Ease and Whizz plugin, plus the very very basic wiggle expression at the end. Note that the object on the right moves erratically and different from the rest.Īnd here's the full lenght of the script of the erratic boi. However, I've used an ease and whizz script so the explosion happens smoothly, and applying the wiggle expression right after it makes it look weird.

I'm doing this in the most basic way: position keyframes and wiggle expression. I'm currently making an animation where I have multiple objects "explode" from the center and then wiggle around. I have posted this same question in the Graphic Design stackexchange, but decided to also post here just in case.

However, I do dabble in motion graphics, and have just recently begin working with expressions. First I'd like to clarify that I'm by no means a professional programmer.
