Steps to build a flatpak from Dweller's Empty Path

Right, before you begin:

This diff applies to the Dwellers Empty Path folder within the archive, referred to as the "game folder" here. Yes, you can indeed apply a diff to an entire directory. Cool, huh?

Prerequisites

• Dweller's Empty Path for Windows (whichever version)
• Node.js and npm
• Flatpak (duh) and flatpak-builder
• From Flathub, org.freedesktop.Sdk and org.freedesktop.Sdk.Extension.node12

How to

• Run dos2unix package.json in the game directory to apply the patch properly.
• Run patch -p1 -ui dweller.patch in the game directory, usually Dwellers Empty Path.
• Run npm install in the www directory. We need the node_modules in there.
• Run dos2unix www/js/rpg_managers.js to change the line endings in that file, we'll need to patch it. You'll get an error otherwise.
• Then, run flatpak-builder build mybuilddir io.itch.tuyoki.DwellersEmptyPath.yaml.
