Primitive Dependency Injection for Unity

The primitive dependency injection system for prototypes assembled on the knee.

Installation

Installation as a unity module via a git link in PackageManager:

https://github.com/elmortem/dependincyinjection.git?path=Packages/dependincyinjection

Or direct editing of Packages/manifest is supported.json:

"com.elmortem.dependincyinjection": "https://github.com/elmortem/dependincyinjection.git?path=Packages/dependincyinjection",

Main types

InjectAttribute

Mark construtor or method with them if you want to inject parameters to instance.

Example:

public class LevelManager
{
	private readonly AssetSystem _assetSystem;

	[Inject]
	public LevelManager(AssetSystem assetSystem)
	{
		_assetSystem = assetSystem;
	}
}

public class Movement : MonoBehaviour
{
	private MovementSystemConfig _movementSystemConfig;

	[Inject]
	public void Construct(MovementSystemConfig movementSystemConfig)
	{
		_movementSystemConfig = movementSystemConfig;
	}
}

DIContainer

DI container class.

Example:

DIContainer.Root.BindAsSingle<LevelManager>();

IDIMaker

Base DI interface.

Example:

public class AssetSystem
{
	private readonly IDIMaker _maker;

	[Inject]
	public AssetSystem(IDIResolver resolver)
	{
		_maker = maker;
	}
	
	public AssetLoader MakeLoader()
	{
		return _maker.Create<AssetLoader>();
	}
}
