Just add one file to your game install to install GDPatch. No game decompiling required. Delete it any time to go back to a vanilla game install.

GDPatch supports all major versions of Godot 4.x, and runs on Windows, macOS, and Linux. If you’re playing a Godot game, GDPatch probably works with it out of the box.

Mods are loaded at runtime and never touch your game files. Install mods by simply unzipping them in the mods folder.

Edit any line of your target game’s source code using GDPatch’s Lua patcher system. Increase your compatibility with game updates and conflicting mods.

GDPatch.patch_script_as_text(
  "Scripts/Player.gdc",
  function(ctx, src)
    return src:gsub(
      "const MAX_HEALTH = 10",
      "const MAX_HEALTH = 100"
    )
  end
)
