Object on end of a string - Cool Idea; How to Execute?
on Aug 17, 2010 at 5:53:13 pm

Hey guys,
I have a question that's not so much a pressured troubleshoot.
i have a great idea but no where to start. Motion behaviors behave so violently inconsistent
that I've lost a lot of trust in them.
The idea is simple:
I want to have an object (say, a rectangle) drop from the "ceiling" on a string that draws taught
whenever the object reaches the end of the string. I want it to pop with some realism, causing
the object to shake and spin.
I'm thinking of when someone drops a necklace while still wrapped around one finger.
That *snag* and sway that happens is what I am looking for.
I appreciate you guys so much for your help. You are all awesome.
Thank you for any advice you can give on behaviors and all things Motion.
-LS

You might try the Spring simulation behavior to get started.

Can you give an example of a behavior acting "violently inconsistent"? I've never seen that.

Check out my Particle Party tutorial. I think it can get you a step in the right direction. Best of luck.

Yeah, I can check out Spring, that's a good idea.
Has anyone ever made a physical string, that moved like one, in Motion?
///
"violently inconsistent" or just not working at all despite parameters being adjusted.
Quantize has never worked for me. I always result to a Strobe filter. In this instance
it was pretty effective. I liked the result - the black shapes.

I'll check out Particle Party for getting instructions on how to do this then tell you
what I think. I haven't had a chance to look at it yet.

Thank you guys for your help!

[Landon Satterfield] "Has anyone ever made a physical string, that moved like one, in Motion?"

It's fairly straightforward to make a swinging pendulum out of a solid line, but do you want a string that will go slack or taut in a realistic way? If so, not sure how you'd do that in Motion without tediously having to hand-animate points on a Bezier shape.
