This repository contains a minimal example for a Minecraft mod that uses Lambda's API.
It aims to be as self-explanatory as possible for developers with minimal experience.
We use ClassGraph to scan Fabric's classloader and load resources at runtime.
These resources include but are not limited to:
- Modules
- Commands
- Pre/Post processor for building
- Various Minecraft objects for which they don't have defined lists (list of entity, etc.)
If you know a little bit about classloaders and reflection, you will realize that as long as your class matches the signature
we are looking for, the resource will be found by the reflection tool and it will just work.
Create an object extending com.lambda.module.Module.
You can create the object (or the class with an empty constructor) anywhere you want in your codebase.
However, we recommend to keep your code structured by placing them in group.modules (ex: com.lambda.modules).
Once this is done, you can start coding your module by adding logic and settings. See existing modules for examples.
The process is very similar to adding modules.
In group.commands (ex: com.lambda.commands), create an object extending com.lambda.command.LambdaCommand and implement CommandBuilder.create.
This function provides a CommandBuilder scope which is collected by the super class and then dispatched to the game to register it.
In gradle.properties, there are two variables that control the version of Lambda and which release type to use.
If you wish to use a snapshot releases of Lambda, change mavenType to releases and lambdaVersion to either version-SNAPSHOT to get the latest snapshot or
a specific snapshot date (ex: 0.1.0+1.21.11-20260405.194419-31).
For official releases, set mavenType to releases and lambdaVersion to the lates available version (ex: 0.1.0)
Please note that snapshot releases offer no assurance of compatibility with the latest release. That being said, you are allowed to use snapshots
for your addon for bug fixes.
