custom property parameter OnChanged callbacks 2005-06-19 - By benp

actually, could someone try this for me?
-load the self installing plugin attatched (after renaming it to
updateTest_plug.pys)
-run in the script editor: (in python)
Application.ActiveSceneRoot.AddProperty('updateTester')
-inspect the updateTester PPG, and step forward through time.
-logged in the script editor, do you get something like:
"updateTester :: X_OnChanged :: 0.0"
every time you advance a frame?
?
cheers
