Yeah, I’ve used Java/JVM a lot and I appreciate the platform independent aspects.
I’ve heard Python people say that their app-design philosophy is to build most of it in Python but drop down into C for the bits where they want to optimize performance in the extreme. So they sacrifice some of the run-anywhere convenience for that. I would use Python myself but the lack of a nicer type system with generics drives me nuts, so I was hoping a similar technique would be available in Java/JavaFX. I hadn’t considered the gaming engines. I’ll take a look at those. thanks, Rob > On Sep 20, 2023, at 3:51 AM, John Hendrikx <john.hendr...@gmail.com> wrote: > > The idea behind JavaFX (and most Java API's) is to provide a platform > independent API, allowing you to write things once and have it run on all > supported platforms.
