Learn how to use NodeCanvas

Visual Debugging

NodeCanvas has a rather informative and advanced runtime visual debugger. In play mode and while a behaviour is running, you are able to see exactly what’s going on within the graph editor window, where nodes and their connections will get highlighted with specific colors to indicate their status. In the context of behaviour trees, these have a more specific meaning as follows.

  • Blue is for Resting.
  • Yellow is for Running, along with a clock icon.
  • Green is for Success, along with a checkmark icon.
  • Red is for Failure, along with a cross icon.


Also remember, that you can Live Edit the graph while it’s running as much as you wish. Adding nodes, connecting disconnecting etc.
