Thanks Michael, your example is very clarifying! Verstuurd vanaf mijn iPad Op 24 feb. 2020 om 05:14 heeft Michael Heuer mailto:heuermh@gmail.com> het volgende geschreven: Hello Herman, I don't think you need to pass values to the sporked functions. Scoping rules allow the sporked functions to access variables declared in their enclosing class, e.g. 0 => int centralpos; spork ~ doSomething(); spork ~ doSomethingElse(); 2::second => now; 42 => centralpos; 2::second => now; 0 => centralpos; <<<"done">>>; fun void doSomething() { while (true) { if (centralpos == 42) { <<<"hello from doSomething!">>>; } 250::ms => now; } } fun void doSomethingElse() { while (true) { if (centralpos == 42) { <<<"hello from doSomethingElse!">>>; } 500::ms => now; } } Do remember to advance time everywhere or things won't work correctly. Hope this helps! michael On Feb 21, 2020, at 2:11 AM, herman verbaeten mailto:hverb54@hotmail.com> wrote: Hi, I'm in big trouble. I'v been trying for a long time now to change an argument in a running function. As you can see in my script i set a certain central pos ("70000")to buf.pos as a central position in my soundbuffer and i let my function LFOtoPOS circle around it. Once the "spork" instruction has started the process i can't figure out how to addresss the argument "centralpos" to change it on the fly or by another function or parameter. Some help please ...
