Plugin problem: MSPhysics

Hello everyone,

I have a problem with MSPhysics. After installing the AMS library and MSPhysics, starting Sketchup, I get this error message:

Errore di caricamento del file /Users/mylo/Library/Application Support/SketchUp 2020/SketchUp/Plugins/MSPhysics/main_entry.rb

Thanks for your help

MSPhysics is no longer compatible with recent SketchUp versions because of changes SketchUp has implemented in its API.

All right, thank you

@Rich-O-Brie
Do you (or anyone else) know of any products, either free or paid, that provide similar functionality to MSPhysics? I'm using Sketchup 2024. Thanks, Jason

@Jason2025 Not yet.

Implementing a fully functioning Physics engine inside SketchUp is not a simple task. The fact Anton pulled it off at such a young age speaks volumes of his ability.

We are actively pursuing getting this updated but he is enjoying his early 20s. I believe asking him to undertake such a massive project without compensation is not feasible.
