Developing:

What follows is a non-exhaustive guide on how to first build the patch, it won't go into details on how to actually work with Harmony or how to approach the patch development. If you're looking for those, read Harmony's documentation, MonoMod's documentation and check out ILSpy.

Building:

---

• [Optional] Build mono with a local prefix.
• Clone this repository recursively.
• Build the VisFree compiler (check the project's README for instructions).
• [Optional] Build the stubs and support libraries.
• Copy any necessary dependencies (such as game assemblies) into the deps folder, refer to the dot files included.
• Build one or all of the included projects, you have a few optional, configurable parameters:
  • DEPS_FOLDER: Where the referenced game assemblies are.
  • MONO_PREFIX: Where your mono install is.
  • COMPILER: Where your VisFree.exe assembly is.

Example:

export CONFIGURATION=Debug
export COMPILER=VisFree/bin/Debug/VisFree.exe
export MONO_PREFIX=~/mono-6.12.0.122/built
export DEPS_FOLDER=~/.steam/steam/SteamApps/common/Celeste
git clone --recursive https://github.com/JohnnyonFlame/FNAPatches
(cd deps/Harmony && wget https://github.com/pardeike/Harmony/releases/download/v2.2.1.0/Harmony.2.2.1.0.zip && unzip Harmony.2.2.1.0.zip)
(cd deps/MonoMod && wget https://github.com/MonoMod/MonoMod/releases/download/v22.05.01.01/MonoMod-22.05.01.01-net452.zip && unzip MonoMod-22.05.01.01-net452.zip)
(cd deps/FNA && wget https://github.com/JohnnyonFlame/FNAHacks/releases/download/IntPtr-SoundEffect/FNA_3d954a5-aarch64.tar.gz && tar zxvf FNA_3d954a5-aarch64.tar.gz --strip-components=1 --wildcards dlls/\*.dll)
make -C VisFree
