Compiling Friday Night Funkin'++

This guide should help you compile Friday Night Funkin'++.

0. Setup
   • Download Haxe from Haxe.org (better be 4.3.4, 4.2.5 won't work with this shit.)
1. Cloning the Repository: Make sure when you clone, you clone the submodules to get the assets repo:
   • git clone --recurse-submodules https://github.com/FunkinCrew/funkin.git
   • If you accidentally cloned without the assets submodule (aka didn't follow the step above), you can run git submodule update --init --recursive to get the assets in a foolproof way.
2. Install hmm (run haxelib --global install hmm and then haxelib --global run hmm setup)
3. Install all haxelibs of the current branch by running hmm install
4. Setup lime: haxelib run lime setup
5. Platform setup
   • For Windows, download the Visual Studio Build Tools
     • When prompted, select "Individual Components" and make sure to download the following:
     • MSVC v143 VS 2022 C++ x64/x86 build tools
     • Windows 10/11 SDK
   • Mac: lime setup mac Documentation
   • Linux: lime setup linux Documentation
   • HTML5: Compiles without any extra setup
6. If you are targeting for native, you may need to run lime rebuild PLATFORM and lime rebuild PLATFORM -debug
7. lime test PLATFORM ! Add -debug to enable several debug features such as time travel (PgUp/PgDn in Play State).

Troubleshooting

While performing the process of compilation, you may experience one of the following issues:

PolymodHandler: extra field coreAssetRedirect

Installing funkin.vis from https://github.com/FunkinCrew/funkVis branch: 98c9db09f0bbfedfe67a84538a5814aaef80bdea

If you receive this error, you are on an outdated version of Polymod.

haxelib run hmm reinstall --force polymod

You can also try deleting your .haxelib folder in your Funkin' project, then reinstalling all your Haxelibs to prevent any other errors:

rm -rf ./.haxelib
haxelib run hmm reinstall --force
