npatch

npatch, a patcher for ragnarok online made with nodejs.

Installation

• Download the repository as zip.
• Extract that zip file.
• Make sure you have nodejs and a text editor for .js files.
• Open up cmd and go to the main directory of the project.
• Run npm install to install dependencies.
• Run npm install pkg -g so you can create the .exe client (cmd only) for the patcher.

Patch Server

This is required so that the patcher can download the files from the web.

• Edit config.yml on the main directory, and change the patchKey to the desired patch key you want and the port you want.
• Run node patchServer on your cmd

DO NOT CLOSE THE PATCH SERVER OR YOU WON'T BE ABLE TO DOWNLOAD THE PATCH FILES

Encoder

• Go to the /src/encoder folder and place all your files that you want to patch inside the content folder.
• Once done, open up data.yml and change the PatchFileName to the desired file name of the patch that you want.
• Then, add the file names that you would want to be included in that patch. For example,

patches:
  # this would be the name of the output file
  - PatchFileName1:
    # an array of the files to add to the patch
    - FileToPatch1.txt
    - FileToPatch2.txt

  # Second patch
  - Patch2:
    # an array of files to add to this patch
    - File1.txt
    - File2.lua

• You could add any kind of file that you want on the array.
• After doing all that, go back to the main directory and run node encode.
• Once that is done, go to the src/encoder/output folder and place all the .npatch files to the src/server/patches folder.
• Open up patchList.yml file inside the src/server folder and add the names of the patch files. Example

- PatchFileName1
- Patch2

• After that, close the patch server and open it up again for the new patch file changes.

Client

• Make sure you have pkg installed, if not simply run npm install -g pkg on cmd.
• Open up config.js and place the patchKey and port of the one that you placed on the config.yml file on the main directory.
• The host is the ip of where the patch server is being run on.
• After all that, go back to src/client folder and run pkg index.js --target=all --output=patcher.exe
