RS Mod

RS Mod is a server that is highly flexible and user-friendly. We allow the developer to make and create any sort of plugin they wish without having to modify the core game module. People without developing experience can have others make plugins for them and simply drop them into the Plugins module and it'll automatically load on the next server startup!

Getting Started

You can learn how to get started here: RS Mod Wiki

Installation

There's two ways to launch RS Mod. One is for users who want to look into the code and possibly create their own content. The other is for users who simply want to run the server as fast as possible and log in quick.

I want to run the server quickly

• Go to the repository's release page: Releases
• Download the latest release (note: not the source code package)
• Extract the archive on your desktop (or anywhere of your preference)
• Open the extracted folder and open the following directory: game-${version-number}/bin
• If you are running Windows, run the game.bat file. If you are running Linux or Mac, run the game file
• The first time you launch it, you will receive a prompt stating that you do not have an RSA private key. Enter y on your terminal/command prompt and wait for a message stating that your key was created. Do not close the terminal/command prompt
• Once your key is created, you will have to follow the instructions on the terminal/command prompt
  • You need to copy the public keys you are given and replace them in your client
  • In your client, you can find the text BigInteger("10001 which will usually be the place where you need to replace both the public keys (the "10001" key is usually the same)
  • Once you have replaced the keys in the client, you can restart the server and launch your client
• The server release comes with a cache and XTEA keys you can use. Current revision: 180

I want to run the server and begin making my own content

1) Clone/Download the Repository

• Go to the repository page: RS Mod
• Clone or download the repository
• Extract the repository in your desktop (or anywhere else you prefer)
  • Note: make sure you use Extract here and not Extract to rs-mod-master\, unless you know what you're doing (it can lead to silly mistakes when setting up your project)

2) Open the project in IntelliJ

• If you do not have IntelliJ, you can download it from here: https://www.jetbrains.com/idea/download/
• In your IntelliJ window, go to the top-left menu bar and navigate to File -> New -> Project from Existing Sources...
• Select the RSMod repository which you downloaded on the previous step
• In the Import Project window, select Import project from external model -> Gradle
• In the next window you want to select the following and unselect anything else:
  • Select Create separate module per source set
  • Select Use default gradle wrapper (recommended)
  • In the Global Gradle settings section:
    • If Offline work is selected, unselect it
• Give the project a bit of time to create and index its files

3) Install RSMod

• On the top-right there should be a box Add Configuration..., click on the box
• On the top-left of the Run/Debug Configurations window, click on the + button
• Select Gradle from the drop-down menu
• In the Unnamed Gradle task, you should now fill in the Configuration
  • Gradle project click the folder button on its right side and select the :game option
  • Tasks set value to install
  • Arguments set value to -x test
• Now hit the Ok button
• Next to the new button that should appear where the Add Configuration... was previously, there should be a green run button, click on that and let the installation begin.

4) RSA key setup

RSA is a method to stop man-in-the-middle (MITM) attacks on packets. RS Mod has this method enabled by default, no two servers should use the same private key so you must create your own:

• After the install task completes, it will print out a message on the IntelliJ console
• Once your key is created, you will have to follow the instructions on the terminal/command prompt
  • You need to copy the public keys you are given and replace them in your client
  • In your client, you can find the text BigInteger("10001 which will usually be the place where you need to replace both the public keys (the "10001" key is usually the same)
  • Once you have replaced the keys in the client, you can restart the server and launch your client

5) Choose your revision

Now you're ready to start choosing the direction of your server!

• Go to the archives page and select a revision you want your server to run on: https://archive.runestats.com/osrs/
• Download whichever archive you want
• Open the archive that you downloaded
• Copy the files in its "cache" folder and place them in your RS Mod folder ${rsmod-project}/data/cache
• Create the folder ${rsmod-project}/data/xteas/
• Copy the file xteas.json and place it in the xteas folder you just created

6) Run the Server

This step is similar to step 3) Install RSMod

• On the top-right there should be a box Add Configuration..., click on the box
• On the top-left of the Run/Debug Configurations window, click on the + button
• Select Gradle from the drop-down menu
• In the Unnamed Gradle task, you should now fill in the Configuration
  • Gradle project click the folder button on its right side and select the :game option
  • Tasks set value to run
• Now hit the Ok button
• Next to the new button that should appear where the other configuration was previously, there should be a green run button, click on that and the server should begin to run.

Troubleshooting

• Where can I get a client?
  • You can get a client from https://www.rune-server.ee/runescape-development/rs2-server/downloads/684206-180-rsmod-release.html
• I receive a Bad session id message on the log-in screen
  • This means the RSA keys on the client do not match the ones created on the server. You should try to follow the steps in 4) RSA key setup again.
• I receive a Revision mismatch for channel console message when trying to log in
  • Find the revision of your client (not cache)
  • Open ${rsmod-project}/game.yml
  • Edit the value for revision: 180 to match your client's revision
• I receive a error_game_js5connect error on the client console
  • You need to launch the server first and then the client
• When following 2) Open the project in IntelliJ my IntelliJ throws the error Build model 'org.jetbrains.plugins.gradle.model.ExternalProject' for root project 'gg.rsmod'
  • This appears to be an issue that can be solved by upgrading your IntelliJ
• I receive a java.lang.NoClassDefFoundError: Could not initialize class class_name_here when trying to log into the client
  • The RSA key you copied to the client should not include \n at the end - remove it.

FAQ

One or more of my plugins stopped working

• When you buy, or create, and use a Plugin JAR - the plugin uses code it assumes you have on the core game module when it was written. If for some reason you move, rename, or completely delete the code that the plugin is using - the plugin will stop working.
• Notes:
  • You can add new code to the game module without this being an issue, this includes adding code to existing methods and files. However, it's best to avoid writing code to the game module and you should always opt to write a suggestion for the RS Mod creators to add specific features to the official game module.

I have done some modifications to the game module. How can I tell if one of my plugins is no longer compatible?

• The only way to check is to download the plugin's source files and run it on your server and see if it compiles correctly!
• Notes:
  • You only have to worry about JAR plugins suddenly becoming incompatible when you edit the game module code
  • Delete or move the JAR plugin when you add the source plugin, otherwise the plugins will conflict when trying to bind them on server start-up
  • In the future, we will add a tool to check if any of your JAR plugins are no longer compatible with your game module

I would like a feature added to the core game module

• If you would like a feature added, you can create a Pull Request on GitHub or contact rspsmods@gmail.com

I found a bug, where can I report it?

• You can report them as Issues on GitHub or contact rspsmods@gmail.com
