hello,
here i try to make simple loop in Processing and trigger sound via OSC in SuperCollider using OpenObject Quark
the problem is in scene1 i want to trigger sound just once not every frame
how to achieve this?


//SuperCollider
(
OpenObject.start;
Ndef(\wn,{|t_trig|WhiteNoise.ar(0.1!2)*EnvGen.kr(Env.perc(0.03,0.3),t_trig)});
Ndef(\wn).publish(\test);
)

1.      //Processing
   
         import netP5.*;
         import oscP5.*; 
         NetAddress sc;
         OscP5 osc;
         int startTime;
   
         void setup(){
         size(768,576);
         frameRate(12);
         rectMode(CENTER);
         osc= new OscP5(this, 12000);
         sc= new NetAddress("127.0.0.1", 57120);
         osc.send("/oo", new Object[] {"test","play"}, sc);
   
         }
         void draw(){
         background(0);
         fill(255);
         noStroke();
   
         int m = millis() - startTime;
                                                                //scene1
         if(m<2000){
           rect(width/2,height/2,width,height);
           osc.send("/oo", new Object[] {"test","set", "t_trig",1}, sc);
                                                               //scene2
         } else if (m<3000){
           rect(width/2,height/2,width*0.5,height*0.5);
         }
   
         else if(m<5000){
         startTime=millis();
         }
   
         }
   
         void stop ()
         {
             osc.send("/oo", new Object[] {"test", "stop"}, sc);
         }
