python states and setAttribValue Sept. 23, 2024, 3:32 a.m.
ohh yep.. my bad, sorry... but even with the setAttribVale()... it says:
as I said, I am running this script from a a Python HDA states... how can I modify it if it is read-pnly?
hou.GeometryPermissionError: Geometry is read-only.

python states and setAttribValue Sept. 22, 2024, 1:29 p.m.
Hello
I am working in a HDA, and using Python Viewer States... I would like to modify (write) a primitive attribute (primnum 0 for example) with the mouse wheel.
so my code is:
but it gives me an error:
but the polygon class has that method, why it does not work?
how can I do write values on primitives using python viewer states?.. any advice?
Thanks you

hi
I am writing a HDA python viewer state.
I would like to do something when the "r" key is pressed.
I wrote this python line to do that:
but when I test the HDA and press "r", it active the "rotate" tool instead of staying in my view state.
how can I avoid it?
Thanks
