	Andy, I set the fixed update time interval with dropdown menu Edit/Project Settings/Time. Then just create a script that has a FixedUpdate() function (instead of the standard Update() function) and it will loop once every fixed update time interval. From there you can do anything you need. I am not sure it can be set dynamically through scripting. I am now creating 32 bit 96k waveform samples for Unity with Csound and using them as looped waveforms in the browser plugin without problems. :) Brian ---------------------------------------- > Date: Sat, 13 Nov 2010 12:13:02 -0500 > From: andy.fillebrown@gmail.com > To: csound@lists.bath.ac.uk > Subject: [Csnd] Re: Unity Audio Envelopes/Creating Waveform files > > Wow, thanks for posting this info!

	Excellent! It works via scripting, too (e.g. Time.fixedDeltaTime = 0.001;) Are you doing any source code management with your Unity file structures? I've got it working fairly well with a local SVN repository on my hard-drive, but I'm not sure the setup will work with collaboration. The way Unity keeps moving things around and deleting keyed files is making things difficult. Regardless, knowing about the fixedDeltaTime setting is making using Unity fun again =) All my work-arounds are unnecessary now that I can control Unity's "k-rate".

Subject	[Csnd] Unity/Csound Algorithmic JI Example
	I put together a quick example of Unity3d browser plugin doing a simple just intonation pattern with 3 "oscillators", each using a 32bit 96k waveform generated by Csound. Total applet size is 59kb. Requires Unity3d browser plugin, Windows and Mac only. http://bwong.ca/Aunity.html Andy, Good to know about Time.fixedDeltaTime, I will be experimenting with that. The example uses simple linear envelopes and a "k-rate" of .01. Other than frequent paranoid backups I have not been using any code management. I am not familiar with SVN, but certainly would welcome a collaborative effort.

I have only been playing with Unity for a couple of days and have not delved much into the audio aspects yet, so I appreciate the info. Are you using the deltaTime variable for the Time class? In my example I used Time.delta time to make the cube rotation speed independent of frame rate. Just an idea, but possibly it might help to apply this to the object movement. Here is the source code for my Rotate.js script : > >>>>>>>>>> var speed = 5.0; > >>>>>>>>>> function Update () { speed = speed + Input.GetAxis("Horizontal"); transform.Rotate(0, speed*Time.deltaTime, 0);} > >>>>>>>>>> You can find the documentation for the Time class in the Scripting Reference. > >>>>>>>>>> BW > >>>>>>>>>> > >>>>>>>>>> ---------------------------------------- > >>>>>>>>>>> Date: Tue, 19 Oct 2010 06:07:52 -0400 > >>>>>>>>>>> From: andy.fillebrown@gmail.com > >>>>>>>>>>> To: csound@lists.bath.ac.uk > >>>>>>>>>>> Subject: [Csnd] Re: OT : Unity browser test > >>>>>>>>>>> > >>>>>>>>>>> Hi Brian, > >>>>>>>>>>> > >>>>>>>>>>> I've been testing out Unity3D for a few weeks and I've found that > >>>>>>>>>>> there are some big issues with the "Audio Source" game objects that > >>>>>>>>>>> result in pops and clicks on some systems, particularly XP.

Well, the video is interactive, the music is not. The music is a Csound piece (pinkcube#1) I did about a year ago. > >>>>>>>>>>>> Unity allows Ogg Vorbis files and has optional streaming. It requires a browser plugin to be installed. Unity is a game development platform which can build for web, mobile, standalone, or console, and the web browser plugin in particular is impressive, on XP at least. I would be interested in hearing whether it works on the broad range of platforms/browsers used by the people here. > >>>>>>>>>>>> http://bwong.ca/gcube.html > >>>>>>>>>>>> > >>>>>>>>>>>> > >>>>>>>>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>>>>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>>>>>>>> Discussions of bugs and features can be posted here > >>>>>>>>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>>>>>>>> > >>>>>>>>>>>> > >>>>>>>>>>> > >>>>>>>>>>> > >>>>>>>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>>>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>>>>>>> Discussions of bugs and features can be posted here > >>>>>>>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>>>>>>> > >>>>>>>>>> > >>>>>>>>>> > >>>>>>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>>>>>> Discussions of bugs and features can be posted here > >>>>>>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>>>>>> > >>>>>>>>>> > >>>>>>>>> > >>>>>>>>> > >>>>>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>>>>> Discussions of bugs and features can be posted here > >>>>>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>>>>> > >>>>>>>> > >>>>>>>> > >>>>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>>>> Discussions of bugs and features can be posted here > >>>>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>>>> > >>>>>>>> > >>>>>>> > >>>>>> > >>>>>> > >>>>>> Send bugs reports to the Sourceforge bug tracker > >>>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>>> Discussions of bugs and features can be posted here > >>>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>>> > >>>>>> > >>>>> > >>>>> > >>>>> > >>>>> -- > >>>>> Michael Gogins > >>>>> Irreducible Productions > >>>>> http://www.michael-gogins.com > >>>>> Michael dot Gogins at gmail dot com > >>>>> > >>>>> > >>>>> Send bugs reports to the Sourceforge bug tracker > >>>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>>> Discussions of bugs and features can be posted here > >>>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>>> > >>>>> > >>>> > >>>> > >>>> Send bugs reports to the Sourceforge bug tracker > >>>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>>> Discussions of bugs and features can be posted here > >>>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>>> > >>> > >>> > >>> Send bugs reports to the Sourceforge bug tracker > >>> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >>> Discussions of bugs and features can be posted here > >>> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >>> > >>> > >> > >> > >> Send bugs reports to the Sourceforge bug tracker > >> https://sourceforge.net/tracker/?group_id=81968&atid=564599 > >> Discussions of bugs and features can be posted here > >> To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > >> > > > > > > Send bugs reports to the Sourceforge bug tracker > > https://sourceforge.net/tracker/?group_id=81968&atid=564599 > > Discussions of bugs and features can be posted here > > To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > > > > > > > Send bugs reports to the Sourceforge bug tracker > https://sourceforge.net/tracker/?group_id=81968&atid=564599 > Discussions of bugs and features can be posted here > To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound" > Send bugs reports to the Sourceforge bug tracker https://sourceforge.net/tracker/?group_id=81968&atid=564599 Discussions of bugs and features can be posted here To unsubscribe, send email sympa@lists.bath.ac.uk with body "unsubscribe csound"
