Whats the Goal?

The goal of this project is to fully convert the original Friday Night Funkin' Legacy Branch, into a fully modern Haxe environment, while keeping the gameplay and behavior as accurate to the original as possible

Specifically, this project aims to:

• Port the original 0.2.x Legacy branch of Friday Night Funkin' to modern Haxe (4.3.7+)
• Maintain compatibility with current versions of HaxeFlixel and Lime
• Clean up deprecated or outdated code
• Preserve vanilla behavior and logic wherever possible
• Introduce modern, optional quality-of-life improvements that do not alter the original experience unless enabled
• Add Legacy and Modern Chart support across all Friday Night Funkin' versions
• Maintain the original Open License

Design

This is not a gameplay overhaul or a redesign.

The intent is:

• Preserve the original feel
• Modernize the technical foundation
• Add optional improvements without forcing changes on purists

Think of it as:

The original game rebuilt on a modern engine foundation.

TL:DR

In short: this branch keeps the classic feel of Legacy while giving it a modern foundation that’s easier to run, maintain, and enhance.

Prerequisites

Before you start, make sure you have the following installed:

• Haxe 4.3.7 — Download here
• Visual Studio Community 2019 (Windows only) — See setup instructions below
• Git — For cloning the repository

Windows Setup (Visual Studio)

If you're on Windows, you need to install Visual Studio Community 2019. During installation:

1. Skip the workloads section
2. Go to the Individual Components tab
3. Select these components:
   • MSVC v142 - VS 2019 C++ x64/x86 build tools
   • Windows SDK (10.0.17763.0)

Getting Started

1. Clone the Repository

git clone https://github.com/Smoffyy/funkin-legacy-haxe-modern.git
cd funkin-legacy-haxe-modern

2. Install HaxeFlixel

Follow the official HaxeFlixel installation guide

3. Install Dependencies

In the project directory, run:

haxelib setup
haxelib install haxelib.json --always

4. Initialize Lime (First Time Only)

If you haven't used Lime before, run:

haxelib run lime setup

Compiling the Game

From the project root directory, run:

lime test <platform>

Replace <platform> with your target: windows, html5, linux, or mac.

For example, to compile for Windows:

lime test windows

Debug Mode

When developing, add the -debug flag:

lime test windows -debug

The compilation process takes a while even on powerful machines. Once complete, you'll find the compiled executable in export/release/windows/bin/ (or the equivalent folder for your platform).

Troubleshooting

Mac users: If lime test mac -debug doesn't work, search for Haxe-specific Mac compilation guides — your setup may require additional configuration.

Next Steps

Once compiled successfully, you can open and run the game from the generated .exe (Windows) or equivalent executable for your platform.
