Gdevelop: Adding an Haxe Exporter

[3mic4nia]

Description

GDevelop 5 Can export his projects to HTML5, but I think this is not enough,
it could be great to generate Haxe code from the project files, in this way, GDevelop games can be easily compiled natively to desktop, mobile, web, and even consoles with the maximum of performances.

It's an interesting idea, though this also means several rewrite of the game engine/renderers/extensions. But Haxe is definitely very interesting and I keep a look at it. Some extensions could be written in Haxe as a proof of concept.

Haxe has this
https://github.com/pixijs/pixi-haxe

Can also compile to js. Will it really compile to native target if it still
uses pixi

Yeah, I wonder if Pixi-Haxe would allow for most of the existing stuff to stay functional, but potentially add on an alternative renderer and event type (Haxe event similar to JS event).

There is also the Kha framework which is used by the Armory Engine and also based on Haxe.

Its interesting, but a huge task. What will it give us apart of native
compile. Also when we say native, how involved will it be to set by our non
programmer user base? Remember we still have cocos and that is a bit
involved to set up locally and doesn't support gdevelops all features

Hello everyone, I'll try to make a simple Haxe exporter for proof-of-concept, it could be useful to look at the GDevelop JavaScript exporter. Can someone show me where is it in the source code?

Personally I think a haxe platform is a bad idea as it means:

1. Trashing all our current extensions away as afaik have compiles to other platforms but not from other platforms to haxe, only export to a language and use pre existing code (pixi-haxe only supports export to JavaScript) So we would have to forbid export to another platform than Js which would kinda beat the purpose
2. It's a lot of work to support multiple platforms
3. Haxe may not be much more Faster? I read that it's slow as it outputs readable instead of optimized code.

If we were to make such a big platform change/addition I would suggest rewriting GDCpp to use SDL2. It would port pretty well to pretty much any platform and be way faster
