Hallo, best boy hat gesagt: // best boy wrote: is there a way to keep track of the number of opened instances of an external? if so, can anyone point me to an example object? You could wrap it inside an abstraction which has a running counter stored in a [value MYOBJECTCOUNT] object. MYOBJECTCOUNT should be unique. The counter then gets incremented with each new instance of your abstraction. You cannot delete objects though without the counter getting out of sync unless you use a Pd with [closebang] or so. For various obvious reasons, this is not a very good general solution, though.

Re: [PD-dev] allow only one instance of external object
hi yes, it's for an external i'm writing. i tried the global counter variable thing you recommended and it works, except for when the first instance is duplicated, or copy/pasted in a patcher. this crashes pd. do you, or anyone else, know of a working example of the global counter variable thing? thanks olli Date: Sun, 23 Mar 2008 10:43:36 + From: [EMAIL PROTECTED] To: [EMAIL PROTECTED] CC: pd-dev@iem.at Subject: Re: [PD-dev] allow only one instance of external object best boy wrote: hi is there a way to keep track of the number of opened instances of an external?

Re: [PD-dev] allow only one instance of external object
hi thanks for your help. i checked out nopoly4 and polypoly, but they both seem to be abstractions and are not very helpful in my case. i need a working solution that prevents the user from creating more than one instance of an external i'm writing. thanks anyway olli CC: pd-dev@iem.at From: [EMAIL PROTECTED] Subject: Re: [PD-dev] allow only one instance of external object Date: Sat, 22 Mar 2008 23:43:23 -0400 To: [EMAIL PROTECTED] Check out nqpoly4 or polypoly, they are both included in Pd-extended and in SVN..hc On Mar 22, 2008, at 11:33 PM, best boy wrote: hi is there a way to keep track of the number of opened instances of an external? if so, can anyone point me to an example object? thanks olli Kostenlos bloggen + eigene Homepage + Fotospeicher = MSN Spaces Kostenlos!___PD-dev mailing [EMAIL PROTECTED]://lists.puredata.info/listinfo/pd-dev As we enjoy great advantages from inventions of others, we should be glad of an opportunity to serve others by any invention of ours; and this we should do freely and generously. - Benjamin Franklin _ Testen Sie Live.com - das Zentrum Ihrer Online-Welt, das Sie mit aktuellen Nachrichten, Sport- und Wetterinfos und vielem mehr versorgt. http://www.live.com/getstarted___ PD-dev mailing list PD-dev@iem.at http://lists.puredata.info/listinfo/pd-dev
