How to do new behaviors ?

Hello. I was pretty fascinated when I heard of Motion: Behaviors, Realtime, XML...Sounded like a nice new sandbox.

However, I really think it sucks after a certain point. Anything I try to do sooner or later has me weeping for some sort of expressions, at least to just feed variables from one parameter into another.

As there seem to be some extremely capable guys on this forum, maybe somebody could hint me on where to find the code of the behaviors and/or a guideline to code new ones ??? I don´t mean the XML-thingies it creates when saving Behavior-Presets...

Cheers, Chris.

Which type of Behavior is not provided, in your view?

Expontential scaling. It's really a pain to create smooth continuous motion scaling to emulate a zoom. It can be done, but it's even more difficult as the scaling axses can't be locked when using bezier controls.

All the best,

Well, what about a parameter-behavior that would allow you to read a parameter from any element in the scene and apply it to any other parameter in the scene ???

Guess you wanted to do, say a tank from a bird´s eye POV, the track-marks realized as particles, the emitter a child to an "aligned to motion path" tank. Normally, the particles would inherit the rotation of the tank, so would flip all the way down when the tank turns. With such a parameter-rerouting behavior you could break that heritage chain and make dependent animation.

You could also do it to create a combined "custom parameter" set wich controls all the objects in the scene, not just the one applied to.


Currently, the only way to "read" is to inherit a value through hierarchy, to "write" is to have parameters set through behaviors or keys.

BTW: If any Apple-Coders read this, why not introduce a color-code for what behaviors do ??? Wich count incrementally, wich multiply values, wich are applicable to what object type...I´m still mapping this so I won´t run into problems...

I'm still trying to get this information from Apple. I have a lot of programming experience in procedural 3d animation which I'd like to re-use..

Hi Graeme,

My request.

"Z space" please, we need Z Space.

Thanks,

Kem, please bug anyone you know at Apple to send me an SDK and I'll try my best.

Hi Graeme,

I don't know anyone at Apple to bug, so I'll send a note to Steve. (g)

Do you know an image stibilizer (behavior or filter) using in Motion.
I can't find it.

Hi Mauro,

I have not seen anything like a stablization behavior in Motion.

Of course not: Behaviors affect objects. Filters affect the pixel-content of a layer.

Stabilisation and Tracking is a mix of both, thus requires a quite different architecture.
