A RuneScape game client from October 2006 which has been modified to work with RuneJS, a RuneScape game server written in NodeJS and TypeScript. This client is not for OldSchool RuneScape - client #435 pre-dates the very first OSRS client by quite some time.

We've no interest in OSRS client hacking, this client exists as a means to develop on RuneJS game servers and will not work with other server emulators.

Running the client can be done either with the pre-built client .jar file from this repository's releases page, or by building the Java code and running it manually in an IDE.

Running the pre-built client requires having Java installed: https://www.java.com/en/

Once installed, go to the releases page, download the latest release, and simply double-click the .jar file file to run it. Alternatively if executing the .jar file does not work, the command java -jar client-435-0.3.jar can be used.

The client will use a set of default configurations if no file is provided. The default client configuration matches up to the default RuneJS server configuration for quick and easy initial setup. It's highly advised that you generate your own RSA public and private keys for long term use.

To provide your own configurations, copy the file ./config/client-435.conf.example.yml to client-435.conf.yaml in your user's home directory, and modify the given configuration for your specific needs.

Gradle provides a wrapper script which downloads the build system to a local cache. This allows you to run the client without the help of an IDE such as IntelliJ. Gradle is also configured to automatically download dependencies.

The following examples use the unix executable ./gradlew, however Windows can replace these with ./gradlew.bat.

The application gradle plugin provides the run task, which starts up the Main client class. With this option, arguments can be provided via --args.

./gradlew run

The jar task can be used to build a jar, which is generated in the build/libs directory.

./gradlew jar
java -jar ./build/libs/client-435-0.3.jar

As of 2024-09-04, our manual builds are done with the following Gradle and Java versions - both appear to produce a similar result:

You can also view our GitHub actions workflow to see the automated build setup.

Our GitHub actions workflow is configured to build a new .jar file upon a tag push event. If you create a release in GitHub, the workflow will fail, because its purpose is to create the release.

The proper process for creating a new build is as follows:

1. git fetch --all (ensures everything is up to date - helps prevent creating a tag that someone else already created)
2. git pull origin master (sync your local repository with the latest changes)
3. git tag -a -s v0.0.X
4. git push origin v0.0.X

Swap out v0.0.X for your actual version, and please try to use the -s flag if you can - using GPG keys to sign tags is preferred.

In a few minutes, a new .jar and release will be ready on the releases page!
