Erupe

WARNING

This project is in its infancy and has no reliable active developer, no documentation, and no support.

This project has been solely developed in my spare time for the educational experience of making a server emulator, which I haven't done before. Expectations regarding functionally and code quality should be set accordingly.

General info

Currently allows a JP MHF client (with GameGuard removed) to:

• Login and register an account (registration is automatic if account doesn't exist)
• Create a character
• Get ingame to the main city
• See other players walk around
• Do quests* (Single player only. Only quests shipped with the game are on the counter. Requires binary quest files not in the repo)
• Use (local) chat*

* = Very limited or buggy.

Installation

Server

1. Clone the repo with git clone https://github.com/Andoryuuta/Erupe.git

2. Install PostgreSQL

3. Launch psql shell, CREATE DATABASE erupe;.

4. Setup database with golang-migrate:

   Windows:

   > go get -tags 'postgres' -u github.com/golang-migrate/migrate/v4/cmd/migrate/
   
   > set POSTGRESQL_URL=postgres://postgres:password@localhost:5432/erupe?sslmode=disable
   
   > cd erupe
   
   > migrate -database %POSTGRESQL_URL% -path migrations up
   

   Linux:

   > go get -tags 'postgres' -u github.com/golang-migrate/migrate/v4/cmd/migrate/
   
   > export POSTGRESQL_URL=postgres://postgres:password@localhost:5432/erupe?sslmode=disable
   
   > cd erupe
   
   > migrate -database $POSTGRESQL_URL -path migrations up
   

   (Replacing postgres:password with your postgres username and password)

5. Edit the config.json

   Namely:

   • Update the database username and password
   • Update the host_ip and ip fields (there are multiple) to your external IP if you are hosting for multiple clients.

6. Place quest/scenario binaries.

   The quest and scenario binary files should be placed in bin/quests/ and bin/scenarios respectively.

Launcher

Erupe ships with a rudimentary custom launcher, so you don't need to obtain the original TW/JP files to simply get ingame. However, it does still support using the original files if you choose to. To set this up, place a copy of the original launcher html/js/css in ./www/tw/, and /www/jp/ for the TW and JP files respectively.

Then, modify the the /launcher/js/launcher.js file as such:

• Find the call to startUpdateProcess(); in a case statement and replace it with finishUpdateProcess();. (This disables the file check and updating)
• (JP ONLY): replace all uses of "https://" with "http://" in the file.

Finally, edit the config.json and set UseOriginalLauncherFiles to true under the launcher settings.

Usage

Note: If you are switching to/from the custom launcher html, you will have to clear your IE cache @ C:\Users\<user>\AppData\Local\Microsoft\Windows\INetCache.
