Do I need a script for this??? Wire Perameters Question

[Ls3D]

Does it need to be realtime? With motion capture controller?
I tried this (key framed) and got a Wire Controller Exception,.. I'm not that wire param savy so perhaps if you provide a sample file LF-Shade will tweak it for you ; )

Here is mine (136k). (http://www.ls3d.com/FTP/wirespheretranzrad.max)

Hi LS3d,

Thanks for posting up the max file and spending time on this little querk thats driving me crazy!!!

Your max file is as good as mine could be and explains what I want perfectly. Basically, as the sphere moves away, I want the radius to increase due to the fact that the tape has gotten longer. I would like it to be real time also.


Is this possible?

[yoni-cohen]

try this:

use a position constraint on the sphere to the two dummies to keep it centered (if needed not a must)

press RMB on the radius and show in trackview

assign a script float to it with the following sintax:
---
**interactive updating based on...
dependson $dummy01 $dummy02
**measure distance...
total = distance $dummy01 $dummy02
**you want only the radius so use..
radius = total/2

works very fast from my tests.
you could make some sort of a hirarchy and then call the dummies using the this.parent I think but I am too tiered to test now..
3:20 in the morning and I got to get some sleep

Thanks yoni-cohen, Im trying what you said but its not doing anything really. Maybe Im missing something.....

[Ls3D]

Yoni, when you wake up please upload the file.. (I can host, pm me if)

Because wire (and script) syntax can be tricky.

listen email me your uploader details and I`ll put it there for you.

the method I used isn`t going thru the wire parameters its a simple float script.

[yoni-cohen]

look in the picture its all about that little script controller no wire.
if you want to do it using wire you will have to put the distance measuring part in a custom atrribute and refer to it when wiring.

edit:
funny, the picture was too big but a zipped max file went under 20k so here you go!!
