Add proper HashLink support

[NotHyper-474]

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!

NOTE: Use the hmm file below to use the forks with the proper fixes for HashLink.

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] OutOfBounds fix when no lime_vorbis and a bit of 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 larsiusprime/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.

Oh my lord please work.

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...

thatd make it ezer 😅

[sphis-sinco]

ill test it soon

[sphis-sinco]

openfl library doesn't seem to be my friend...

[NotHyper-474]

Pull the commit I just pushed and try again, I forgot my fork had a different name lel

[sphis-sinco]

another error but I have a fix for this cuz its happened to me be4

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

[sphis-sinco]

HUH

[sphis-sinco]

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.

[sphis-sinco]

[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.

[sphis-sinco]

im just being hated

[NotHyper-474]

im just being hated

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

Then try again, hmm doesn't usually update the submodules properly

[sphis-sinco]

oh ok

[sphis-sinco]

ok yeah game didnt open for some reason

[sphis-sinco]

kk

Apparently cutsceneType was null.

/**
   * The default callback used when a cutscene is finished.
   * You can specify your own callback when calling `VideoCutscene#play()`.
   */
  static function onCutsceneFinish(cutsceneType:CutsceneType):Void
  {
    try
    {
      switch (cutsceneType)
      {
        case CutsceneType.STARTING:
          PlayState.instance.startCountdown();
        case CutsceneType.ENDING:
          PlayState.instance.endSong(true); // true = right goddamn now
        case CutsceneType.MIDSONG:
          // Do nothing.
          // throw "Not implemented!";
      }
    }
    catch (e)
    {
      if (FlxG.sound.music.endTime != null
        && FlxG.sound.music.time >= FlxG.sound.music.endTime) PlayState.instance.endSong(true); // true = right goddamn now
      else
        PlayState.instance.startCountdown();
    }
  }

[sphis-sinco]

Was that after reinstalling flixel?

yeah

[sphis-sinco]

you forgot the flxSignal changes

[NotHyper-474]

Are you sure the changes are not there?

[sphis-sinco]

I installed the flixel changes from the wrong hmm file

WHOOOPS

[sphis-sinco]

Hashlink is real.

[NotHyper-474]

Decided to remove the changes to the hmm file and put them in a gist I've included in the description, I'll be updating it as needed.
