Sending value through osc

Processing Libraries
1

Hello everyone,

I am working on a project and i would like to understand how to write if value = 0, don’t send osc message, or instead send another value.

if anyone could help me with this, it would mean a lot .

Have all good day everyone

I would like to know how to make an argument saying that if the values Rouge, Vert, Bleu are 0, then no need to send the osc message, or just use the previous OSC message

I see that you had difficulties in formatting your code. Maybe it is easier to just type ´´´ at the beginning and at the end of the code.
Please try to edit.
I don’t see the receiver code here.
On the remoteLocation device you need to extract the values from the message like something as code below. Then you can use these extracted global colors in an if block.

void oscEvent(OscMessage myMessage) {
   if(m.checkAddrPattern("/colors") == true) {
     if(m.checkTypetag("iii")) {  // Three integers in message
      vert = myMessage.get(0).intValue(); 
      rouge = myMessage.get(1).intValue();
      bleu = myMessage.get(2).intValue();
     }  
   }
}

Thank you so much Noel! i am still new to Processing, i don’t know much about how to formate my code but i will do some research about it. and yeah the extracting the values now is really helpful. again i really appreciate your help!
