Hi,

I am struggling a bit creating a bobble head character and was hoping someone could point me in the right direction.

Basically I have a character structure composed of two bodies, a head and torso, and would like for the head to bobble/sway gently back and forth. When the body is in motion or the head is pushed it would sway further than it normally does on it's own. I've tried various joints/motor combinations but the results aren't what I was hoping, but mostly because I am still familiarizing myself with both box2d and with the RUBE editor.

Sorry, I know this should be something I could answer on my own with a little more time playing around, but if there is a quick answer someone could give it would be much appreciated.

Thanks

You could try using some distance joints with frequency and damping set appropriately, like in the 'web' example in the testbed. I've attached a RUBE scene with some examples. The ones at the top differ only in the location of the joint anchors, so you can see how the behavior changes. The one at the bottom also has a rope joint to stop the bodies from being pulled apart too far.

Ah, excellent, thank you, much appreciated.
