I get a message:
/rigidbody/1 1 2 3
/rigidbody/1 3 4 5
What object in max can help me to capture the first line of the message and access it separately.. SO, i can map the data from first line to something and the same with with the data that comes in the second line.
You could send each kind of message on different ports and have separate udpreceive objects per port to deal with the different circumstances.
I suspect however that there is a more logical way to format your data such that you could use the route object, for example, to handle your incoming messages. If you supplied the sending patch it would be easier to diagnose.
I am also queasy about the use of forward slashes in your message. If you need them as part of a filepath, it would be better to use sprintf on the incoming data.
