Support for all official extensions

[czyzby]

• [ ] Bullet.
• [x] Freetype.
• [ ] gdx-pay.

There are currently 4 official extensions with native dependencies: Box2D, Controllers, Bullet (3D physics) and Freetype (TTF font support). The first two are already supported by gdx-backend-jtransc, which is great. Bullet is specific to 3D games (which are far less common than LibGDX 2D games), so it can be put on hold - but the Freetype and Pay extensions support would certainly be beneficial.

Those support GWT? Since they have C++ code I could embed C++, but that would prevent Javascript code to work. Is there a portable pure-java implementation for those?

[czyzby]

No, they do not. I think both have unofficial GWT ports, but they most likely use native JS code or C(++) transpiled to JS. I don't think an official pure Java solution is available, although there seems to be a Bullet Java port.

[intrigus]

The best way would be integrating the native dependencies, generating c++ and then using emscripten to target the web.

[soywiz]

There is no any LLVM to JVM compiler? That should be relatively easy and with java.nio it is possible. And would allow to compile C++ into JVM. The problem with emscripten is that I would have to do for each non c++ target, while the other approach would work everywhere for example generating flash, php, python, lua among others.

Maybe this one or similar? https://github.com/davidar/lljvm

I was able to get it working. For the record:

https://hub.docker.com/r/mhaye/lljvm/ https://github.com/davidar/lljvm/pull/5

docker run -t -i mhaye/lljvm /bin/bash
cd /usr/local/src/testProg && lljvm-cc test.c -o test && java test
Hello world.

It generates a test.class I copied it outside docker and downloaded the runtime:

docker ps
docker cp a88549c3609e:/usr/local/src/testProg/test.class test.class
wget https://github.com/davidar/lljvm/releases/download/0.2/lljvm-0.2.jar
java -cp .:lljvm-0.2.jar test

[soywiz]

So I created this repository: https://github.com/jtransc/java-freetype

Build script fails, but it is a begining: https://github.com/jtransc/java-freetype/blob/master/build.sh

./build.sh

I completely forgot - there's also gdx-pay, which is a definitely important extension. A cross-platform way of adding ads (for example) to your games is crucial, imho.

[soywiz]

We could use: http://lib.haxe.org/search/?v=iap https://github.com/openfl/extension-iap

It should be pretty easy with @HaxeAddLibraries + @HaxeMethodBody

Please create 1 ticket for 1 bug/feature, i create #76 for iap in iOS as first tested platform. Bullet i think need support, after anybody will have real project for test. Freetype already supported on haxe. If need more create new ticket. Close this zombie ticket =)))
