Hi,


I would like to create some handles based on node data (in the State class __init__) and bind them (in createViewerStateTemplate().

I am struggling to get the data in these two parts of the code that you do have acces to in all the Event Handlers.

In __init__ I can type node = scene_viewer.currentNode(), but in createViewerStateTemplate() I did not find a way yet. I did try self.node, tried @classmethod.

Any ideas?


Thanks in advance.

Take a look at the provided examples at $HH/viewer_states/examples.

The kwargs dict is given as an arg to a lot of the event callbacks like onEnter, onDraw, etc.

You can put this in onEnter self.node = kwargs and access it everywhere else afterwards.

Thanks for the help, but sorry I did not specify the problem accurate enough:
I get this error when using self in createViewerStateTemplate()

I just found about of this global keyword, but that also gives me this error when trying to acces from createViewerStateTemplate()

I suspect createViewerStateTemplate() and init are run before any of the event handlers are allowed to be called.

I also thought of creating or running a function there that gets the kwargs into these parts, but then, it seems, the function argument also needs to be (kwargs), which don’t exist there yet.

The state instance doesn't exist at the point when createViewerStateTemplate is called by Houdini. createViewerStateTemplate will register a template for your state which Houdini can use to create instances of your state when requested (e.g. entering the state in the viewport).

Custom python handles are not supported yet.
