Multiple '2D Vector Control' (JSUI)

chaostheory — Tue, 20 Feb 2007 19:05:04 +0000

Right, I’m pretty useless when it comes to Javascript and I’m pretty stuck on what I need to do.

In the JSUI help file there is an object/file called ’2D vector control’. It’s basically a ball which you can drag around in a confined area and get output coordinates and such. I’ve attached the file as an example just in case you can’t find it in Max.

Anyway, I’d like to be able to duplicate the balls so there are multiple balls to control (around 10, maybe more). Is this possible? I know a little Javascript and Actionscript, but not enough to be able to solve my problem so any hints on how this may be achieved would be extremely grateful!

Hi Chris -

I’d already built something similar for a project of mine —
cleaned it up & here it is (attached).

It defaults to 3 controls, but you can specify any number (slows down
a bit around 20).

I didn’t want to deal with having to set individual colors for each
orb, so it just creates a range from the foreground color (first
control brightest, last darkest).

Hope it works for you.

Aaah, attachment didn’t work. Here it is (I hope).

Try this one (no errors).

Thanks for posting the attachment (haven’t had a chance to try it yet though).

I did find a work around whereby I could store multiple coordinates and recall them at any time (thus effectively creating multiple balls). However, if this is more intuitive then I might use this instead.

One other thing, I am using this to develop a VST instrument (for Pluggo). I was hoping to release it as a free download at some point in the future. If I end up using your Javascript solution (depends how CPU hungry it is compared to my solution), would you mind if I distributed it over the internet? You will get credited of course :).

Sure, no problem.

Let me know how it compares to your version.

Hi,

I’m having some trouble including the multiorb within a pluggo. I’m getting the error:

check failed: atombuf_text
check failed: atombuf_text
Starting Build for CHvector.vst…
Processing Script…
error:error-1 locating=
error in line: oneclick.local=

Is there any way around this?

Thanks
Chris
