Installers

An installer is a script responsible for configuring bindings and injecting dependencies into a scene. Injexit provides two installer classes that you can extend.

RootInstaller

The RootInstaller allows to configure most of your bindings in your main scene. Simply extend the RootInstaller class, override its OnBind() method to specify your bindings, and (because it’s a MonoBehaviour) attach it to some root game object in your main scene:

using Silphid.Injexit;

public class AppInstaller : RootInstaller
{
  protected override void Configure()
  {
    // Add your bindings here
    Container.Bind<IFoo, Foo>();
    Container.Bind<IGoo, Goo>();
    Container.Bind<IBar, Bar>();
  }
  
  protected override void Complete()
  {
    // All game objects in current scene have now been injected
  }
}

SceneInstaller

Only in multi-scene scenarios, the SceneInstaller allows your secondary scenes to specify their own bindings and have their game objects injected when they are loaded. You must extend that class and specify a parent installer type as generic parameter, which it will look for in the root game objects of some other scene and use as parent to inherit all its bindings.

using Silphid.Injexit;

public class MySceneInstaller : SceneInstaller<AppInstaller>
{
  protected override void Configure()
  {
    // Add your scene-specific bindings (or overrides) here, if any
    Container.Bind<IFoo, Foo2>();
  }
  
  protected override void Complete()
  {
    // All game objects in current scene have now been injected
  }
}

Because it inherits from SceneInstaller<AppInstaller>, it will look for an AppInstaller in some other scene and use it as parent. It will therefore inherit all the bindings defined in AppInstaller and override the IFoo binding to Foo2 (instead of Foo), but only for that scene. Finally, it will inject all game objects in the current scene and call the OnReady() method.
