from the NVIDIA Omniverse forums regarding Kit, Omniverse Code, Python, and USD.
## Questions
- 3:47 - How do you add an extension via the Extension Manager?
- 8:48 - How do you programmatically add a Python Script to a prim? (Python Scripting Component)
- 23:45 - How do you check what Python scripts a prim has? (Python Scripting Component)
- 27:00 - How can you have your extension interact with a Python Scripting Component?

mati-nvidia/developer-office-hours/exts/maticodes.doh_2023_04_14/docs/README.md | # Developer Office Hour - 04/14/2023
This is the sample code from the Developer Office Hour held on 04/14/2023, Mati answered some developer questions
from the NVIDIA Omniverse forums regarding Kit, Omniverse Code, Python, and USD.
## Questions
- How do I find and execute a Kit Action?
- How do I programatically toggle fullscreen mode?
- How do I move a prim in the forward direction? |

This is the sample code from the Developer Office Hour held on 01/13/2023, Mati answered some developer questions
from the NVIDIA Omniverse forums regarding Kit, Omniverse Code, Python, and USD.
## Questions
- 3:46 - How do you programmatically add a Python Script to a prim? (Python Scripting Component)
- 8:02 - What are the criteria for valid prim and property names in USD?
- 11:14 - How can I swap a prim's material using Action Graph? |
