Adding some spring to motion?

Is there a quick and easy way (a script?) to add some basic spring motion to animated parameters (position / rotation) besides having to use MoGraph and the Delay Effector?

Thanks!

You can use the delay effector on a regular object if you switch the deformer setting to object (or point).
Also the jiggle deformer does this.

Vibrate is an option too.
Vertex map with jiggle localizes the effect.

Ugh. Thanks, guys. I'm such a tool. I've been running R13 since it came out, and yet I haven't properly explored every one of the "new" effectors. Jiggle does the trick!

Cheers!

There's CD Springy Keys as well: http://www.youtube.com/watch?v=93CT94sMnPM

You can also do it with good old keyframes, sometimes a faster way IMO to get the result you want. Faster again with a little scripting.. https://vimeo.com/42471806

Thanks!

You may be interested in my CD Springy Keys plugin:

I'm still having a few issues with the delay effector and jiggle. Specifically, what I'm trying to accomplish, is just a little slight over-run with a simple camera rig. I have the camera attached to a null. The null is controlling the rotation around an object, and the camera is simply moving in and out along the its z-axis.

I can't see any affects, regardless of whether I apply the two effects, mentioned above, to either the camera or the null. Nothing happens. I can take the same effects, and apply them to a simple primitive object, and then they work fine. Are there some odd limitations to using such "spring" effects on nulls or cameras? I can't figure out why there would be.

I would give the wiggle deformer a try.

Another option would be to constrain the camera to a null with a spring constraint and animate the null.

Do you mean the "jiggle" deformer? If so, that's what I can't get to work on the camera nor the null.

Yeah. Thanks. I have tried this, too. It actually seems to be the only solution for doing what I want with a camera attached to a null. However, it too presents a number of little control problems. Also, part of my issue (my own fault) is that I already have my main animation keyframed out. So, getting the spring constrain to work would require some time-intensive reverse engineering of my setup. But I may have no other choice. I really don't want to keyframe the over-runs into the animation, if I can avoid that.

Yeah, jiggle may be the right term. Wasn't sure about it. If you replace the null with a cube (set to be invisible), the deformer should fit.

I can't believe no one has mentioned CS-SpringNull. I've used that many times to add bounce to an objects movement. Very easy to set up and tweak.

Those are some nice-looking aids. However, the spring one seems specifically designed to work in preset space. Whereas, I'm actually looking to add some "over-run" to the existing motion I already have keyframed out.
