OSC Communication
Sequence Diagram
Sequence diagram of OSC messages for automating the test.
Information
The following diagram is an overview of OSC messages between Max and Unity. For a sequence diagram of how to set up a test, see the example test page.
OSC Message List
FYI
Argument in speech marks " " indicate a constant. These string messages are used to trigger functions in the receiving programs.
Max → Unity
