Is building for mobile and web target supported? about raylib-go

[gen2brain]

Building for Android is supported, see here https://github.com/gen2brain/raylib-go/tree/master/examples/android/example . I am working on improved bootstrap script that should work (in theory at least) also on Windows and macOS.

Edit: Also see here for apk game example https://github.com/gen2brain/raylib-go/tree/master/examples/games/floppy

Emscripten is not supported. Maybe someday, if Go llvm support is matured, and also implemented for other platforms besides x86_64, so code can be compiled to bytecode, and then processed with emscripten, something like that I guess.

Wow fast reply!
Great to here that it works for Android already!

About the web target: have you considered using GopherJS instead of Emscripten? That's what all the other projects use to compile Go to Javascript. I don't really know how much work this would be though..

[gen2brain]

I have considered GopherJS, but it seems like a lot of work. raylib-go is wrapper around C library, with C code included in project. Other projects also use cgo where they need, i.e. GL, OpenAL, but have that better isolated. For raylib-go, a lot of parts will need to be rewritten in Go, and then exported back to C code, rlgl.c for example. Something can be done with tags probably, but still a lot of work.

Edit: if not clear, GopherJS doesn't work with cgo, only native Go code.

I had a gut feeling that cgo will be a problem there. I guess then the web target will have to wait :)
Thanks for all the info! Seems like I have to stick to other languages for now sadly.

There is work happening for golang to support WASM. It's looking promising too.

You can currently mix golang and c code and have it compile with emscripten and gopherjs to work together.
Then when the WASM for golang is done, you can move to that.

Here is a good example of this which also has sound working.
https://github.com/naivesound/glitch
picodom is a fast small replacement for react vdom, and is c, but compiled to emscripten
then the golang stuff is compiled to gopherjs and it calls the JS of picodom.

this is not a perfect example, but it shows this works and that its a pretty good potential roadmap for us.

I have not had enough time to really dig into this further, but wanted to raise this.

Ans there is now cayley running 100% in the browser

@gedw99 I only now browsed through projects you linked. Not perfect, but i would like to try some combination of emscripten and gopherjs. Will need to investigate and see how everything can be combined of course. Thanks!

no probs.

if you want to be on the tip here is he WASM for golang

Web target is now partially implemented, there are problems with _emscripten_set_main_loop() function, see #28 .

@gen2brain thats great. Will have a look.
