Is it possible to write a controller support add-on?

Question

I want to use the triggers on my controller to move and have variable throttle/braking intensity like in Gran Turismo. Because the triggers on the controller are separate axes, I can't simply put an axis in the project settings. So I wrote the following script for basic car movement following this page: https://vehiclephysics.com/advanced/custom-addons/

This is the script:

The console then gives me the following error:

Answer 1

Yes, you can write a controller support add-on. The code in your script should work straight away.

However, note that custom add-on components are not supported in the Community Edition of Vehicle Physics Pro. The error you receive happens when trying to implement custom add-ons in VPP CE.
