robovm VS libGDX

Naturally depends on the use case, yet they work good enough to be in business for 20 years.

Unfortunely the best well known, Excelsior JET, is no longer in business, most likely due to GraalVM and OpenJ9 being available as free beer, while PTC, Aicas Codename One are safe in their domains.

There is also RoboVM (https://github.com/MobiVM/robovm) as free beer, however it actually started as a commercial product, and the acquisition from Xamarin kind of stagnated it (naturally).

I think libGDX still uses RoboVM, but I’m not sure if it’s being actively developed anymore.

For iOS the RoboVM project intends to be an AOT compiler for Java bytecode.

Kotlin is not ideal for iOS development afaik (maybe with RoboVM). With regards to Android development, it is perfect. For desktop applications it's good, there are always tradeoffs here. With regards to payment, I believe it is generally the case that you're paid more the harder the language is to learn (so C > C# > Python). This also affects how much people are looking for a certain kind of developer - there are more JS jobs than jobs requiring a C++ developer. Kotlin is a good choice to start though. It's not too complicated, it's not so simple that it's limiting you somehow, it's not too slow for most applications (+ it supports native somewhat) and it has a good environment with stable libraries you can rely on.

Yes, these are the native code compilers for Java, able to target Apple mobile platforms.

Neat, thank you! I'd love to see how it compares to the libgdx IntMap[0].

For anyone interested, LibGDX[1] is a very nice open-source game engine for Java. It is cross-platform (mobile, PC/mac, web). Very popular and well maintained, too.

Source is also available on github https://github.com/libgdx/libgdx to directly check the implementation of a specific classes.

And let me explain, for example jorbis this library has a lot of nested loops in it, i understand why this library using this, but this is really bad. Because when I am trying to use library with this code, this taking so much time to convert ogg to pcm, and yes I know that converting ogg to pcm is a hard process, but I need to optimize my program, make it more better. The main thing is EVERY decoding ogg file library using the same piece of code! And I am not joking for example libgdx.

What the pcm file contains? And what is the structure? What data I should use for converting .ogg file into pcm? Is there any information about pcm files? Is there any repositories in github that converts .ogg files into pcm? (I am already know there is JVorbis, libgdx and jorbis but thats not what i want)

There's a code snippet showing the seed generation and how it feeds into each RNG pattern but it also mentions the use of a "xorshift128+ algorithm" here: https://github.com/libgdx/libgdx/blob/master/gdx/src/com/badlogic/gdx/math/RandomXS128.java

I can't guarantee you'll get a reply, but Mario and Nate's email addresses are in the AUTHORS file.

I found an example for rendering a [Mesh] object using instancing in LibGDX's tests (link), but I'm not sure how to apply that for rendering actual models.

assuming you use that (https://github.com/libgdx/libgdx/blob/master/build.gradle) as your starting point. You first have to ask what it is that your build should cover. Do you need all the spotless checks and release flags and so on or do you just need to package everything up so that it could run.
