Advanced - Softbody Dynamics...

I just pointed my graphics design friend to the Moho 5 demo and she's loving it.

I had created an animation for her before using Moho 4 of two smiling cherries dangling from their shared stems - I animated their "heads" moving back and forth depending on the video it was overlaid onto.

I showed her the new bone dynamics and told her how now I wouldn't even need to do the secondary animation I had to do by hand the first time.

By this time she had got to the "Frank" part of the beginning tutorials when I realized that it's great to have the bone dynamics to help with jiggling parts but it would be even more cool that when the cherry heads bang together they would BOUNCE OFF each other as well!

I'm not sure how this would be set up. In 3D animation programs, usually collision detection is based on a dense triangular mesh.

With Moho, I could imagine perhaps drawing a special kind of outline or similar around the object - or maybe it could be an additioinal attribute of the stroke to >sense collision<??...

Either way, I know the calculation could get deep but I believe it could be kept simple - the same way you can define springiness with bones, perhaps you can simply setup a variable "bounce force" that drives two colliding objects back away from each other by the specified amount - this would be enough to get the bones to react how they do now to add the secondary motions...

I'm sorry, I absolutely thought I posted this in the feature request section!
