Stash Hunting Item Tool recorder plugin for lambda client.

This is a tool for recording the contents of the chests in the stashes in minecraft. In order to keep the program safe, laambda client was used as a base. This is a plugin which could be aded to it.

It is a part of the larger project which included an API, a discord bot and this minecraft mod for recording the items from the packets.

Setup instructions

To achieve coding building and publishing your own plugin most of the following steps are required.

Fork

This is a template repository and can be used as a base to create a custom plugin. Press the Use as template button on GitHub to automatically create a linked fork to this repository.

Clone Repository

Clone the repository to your local machine. Use the link of either your fork or the main repository.

git clone https://github.com/lambda-client/ExamplePlugin

Setup IDE

In this guide we will use IntelliJ IDEA as IDE.

1. Open the project from File > Open...
2. Let the IDE collect dependencies and index the code.
3. Goto File > Project Structure... > SDKs and make sure an SDK for Java 8 is installed and selected, if not download it here.
4. Run the genIntellijRuns Gradle task, or run ./gradlew genIntellijRuns.
5. Open with CTRL+left_click on PluginModule in ExampleModule to open the decompiled lambda dependency. To see the original source code go in the top right corner you can add Sources... and select the lambda-*-api-source.jar.

Configure Gradle

Test if the environment is set up correctly by building the plugin jar using the Gradle tab on the right side of the IDE.

1. Go to ExamplePlugin > Tasks > build > build in the Gradle tab and run the script
2. IntelliJ will create a new directory called build. The final built jar will be in build/libs

Config

Configure the metadata of your plugin in plugin_info.json. The flag main_class must contain the target main class Plugin in this case it is PluginExample.kt

Plugin

The plugin main class will act as a register for the functions a plugin can provide. For example when a new module class is created you have to add this to the onLoad() function of the plugin class.

modules.add(ExampleModule)

Every service is required to be added to the main class in order to index the contents.

PluginModule

A module represents a utility module inside the game. The PluginModule class acts as a wrapper for Module class. For many examples on how a module can work check out the native modules of lambda, or the given example in this project. The difference from the native Module class is that each component of a plugin requires a reference to the main Plugin class.

pluginMain = ExamplePlugin

Every PluginModule class will need to be registered to the main plugin class

ClientCommand

Plugins use the same class as the native client for registering commands. Feel free to check out the commands of Lambda Client as a reference.

PluginLabelHud

A LabelHud is used to display information in the player GUI. The PluginLabelHud class acts as a wrapper for LabelHud class. For many examples on how a hud can work check out the native hud elements of lambda, or the given example in this project. The difference to the native LabelHud class is that a referral to the main plugin class is given in the object data.

pluginMain = ExamplePlugin

Every PluginLabelHud class will need to be registered to the main Plugin class.

Background Jobs

If coroutines are needed background jobs can be registered using

bgJobs.add(BackgroundJob)

Mixins

To use mixins, you have to:

1. Register the files in the plugin_info.json in the mixins list.
2. Add the refmap path from mixins.ExamplePlugin.json to the build.gradle source sets.

Build

1. Go to ExamplePlugin > Tasks > shadow > shadowJar in the Gradle tab and run the script
2. IntelliJ will create a new directory called build the final built jar will be in build/libs
3. Put the ExamplePlugin-1.0.jar into your ./minecraft/lambda/plugins folder and run the game.

Publish

Publish your repository in Discord, and we may fork you, or transfer your repository to official plugin organization of Lambda. After review, your plugin may get added to the native marketplace.
