Add proper HashLink support

Linked Issues

Closes #4138

Description

This is quite an old branch of mine that's been sitting on my repository since 2024, finally becoming a PR now that there seems to be a growing interest in building for HashLink. It aims to fix issues that would prevent someone from compiling to HashLink, which could be a pretty useful target for easily making and testing PRs like I did when making #3574.

Feel free to try it out and report any issues you have in the replies!

Dependent on:

• Merge the latest changes from upstream flixel#8
  • Has commit FunkinCrew/flixel@6f8ee63 (#7) which fixes a bug with Flixel signals not being removed, causing crashes.
• Fix rebuilding and keyboard timestamps on HashLink target lime#24
  • Fixes compile errors when rebuilding the HashLink binaries on Lime. Also includes binaries for Windows and Linux (sorry MacOS users)
• [BUGFIX] Fix not working on HashLink (+ some refactoring) FlxPartialSound#4
  • Optional, fixes Freeplay previews not loading for some songs.
• Fix build error on HashLink openfl#7
  • Fixes a compile issue and a shader crash.
• Fixes for HashLink polymod#258
  • Fixes pretty much (almost) all scripts throwing errors.

Known Issues

• DropShadowShader is utterly broken. Fixed by larsiusprime/polymod@045372c (#258)
• Advancing in a Conversation causes a crash. Also fixed by the commit above.
• Chart Editor may randomly crash while messing around. Turns out it's just a bug with HaxeUI.
• Video cutscenes don't work (which was already expected)
• Lime can build but cannot open a debug session. Fixed!
• WiggleEffect shader crashes the game by trying to cast an enum to an int. Fixed by OpenFL PR.
• Some Focus Camera events aren't able to be properly parsed, which causes a crash.

If any features have to be disabled (like video cutscenes), you should make sure to disable them in the project.hxp so that the default build flags enable successful builds.

I keep getting an error when compiling to Hashlink that doesn't happen with windows:

That's because you need the change from FunkinCrew/openfl#7

Maybe I should put back the commits from the PRs in the hmm file...

[macohi]

PolymodAbstractScriptClass.txt(txt becuz github's a [[uh-oh]])

[macohi]

HUH

[macohi]

Everything works but (I'm suspecting) lime keeps fucking it over. Least for me.

[NotHyper-474]

I think you may need to rebuild Lime for HashLink with lime rebuild hl. I'll look into including Windows binaries tomorrow (currently I only have Linux ones) so that rebuilding isn't necessary.

[NotHyper-474]

I managed to rebuild HL on Windows, but for some reason the game just refuses to open bruh, this is some freaking bullshit.

[macohi]

im just being hated

[NotHyper-474]

im just being hated

cd .haxelib/lime/git
git submodule sync
git submodule update --init
