Mimbo - A Friendly Robot

Step 4 Receive OSC Messages in Processing

Mimbo utilizes the accelerometer feature in TouchOSC to send it's acceleration sensor values back to the processing script.

In order to receive OSC messages, an interrupt/event handler method is required. The simplest way to debug OSC event handling is to simply printout whatever is received using code like this:

void oscEvent(OscMessage theOscMessage)
{
     println(theOscMessage.toString());
}

To get the value(s) of a message employ the following command in the oscEvent function:

float myVariable = theOscMessage.get(0).floatValue();

In the case of Mimbo, the OSC Event handler looks like this:

void oscEvent(OscMessage theOscMessage)
{
  // This runs whenever there is a new OSC message
  String addr = theOscMessage.addrPattern(); // Creates a string out of the OSC message
  if (addr.indexOf("/accxyz") != -1) {
    last_accx = accx;
    last_accy = accy;
    accx = theOscMessage.get(0).floatValue();
    accy = theOscMessage.get(1).floatValue();
    accz = theOscMessage.get(2).floatValue();
  }
