# Getting Start(toturial)

![HnMVC architecture](https://4261080576-files.gitbook.io/~/files/v0/b/gitbook-legacy-files/o/assets%2F-LMAsKM_cmrNJsQr2BRS%2F-LMAuovHupyDz2xLnkW0%2F-LMAutZK65vypPC_qOOw%2FHnMVC.png?alt=media\&token=5b42c488-fbc2-43b5-a587-45c3a080e3f3)

###  **1.Create Contex**

* Create a new empty gameobject and add a c# script component.
* Create a contex class drive from class "HnFramework.MVC.Contex", e.g. "XXContex".
* Override function "InitCommand".

###  **2.Create Command**

* Create a SceneCommand or StartCommand class drive from class "HnFramework.MVC.Command", e.g. "XXCommand".
* Override function "InitModel".
* Call function "BindCommand(new XXCommand(this));" in the function "InitCommand" of "XXContex".

```
public override void InitCommand() {
      // Initialize command function, All command class should be create here.
      // Command类初始化函数,所有的Command类应当在此进行创建.
      BindCommand(new Test1Command(this));
      BindCommand(new CubeCommand(this));
  }
```

* Create other bussiness Command class drive from class "HnFramework.MVC.Command".
* Override function "OnStart", and add listener.

```
public override void OnStart() {
      AddListener(CommandEvent.GetScore, OnGetScore);
      AddListener(CommandEvent.AddScore, OnAddScore);
  }
```

###  **3.Create Model**

* Create model class drive from class "HnFramework.MVC.Model", e.g. "XXModel".
* Call function "BindModel(enum, XXModel.GetSingleton());" in the function "InitModel" of "SceneCommand".

```
public override void InitModel() {
      // Bind model function, model instance will be destroy with the scene 
      // while you call the method Model.GetInstance, and it works in whole life time 
      // while you call the method Model.GetSingleton.
      // Model数据类在此进行绑定,调用GetSingleton则该数据类全局有效,GetInstance则只在当前场景有效,
      // 场景销毁则该数据类也进行销毁.

      //BindModel(ModelType.ScoreModel, ScoreModel.GetInstance<ScoreModel>());
      BindModel(ModelType.ScoreModel, ScoreModel.GetSingleton<ScoreModel>());
      // BindModel(ModelType.OtherModel,
      // BindModel(...
  }
```

### &#x20;**4.Create Mediator**

* Create mediator class drive from class "HnFramework.MVC.Mediator", e.g. "XXMediator".
* Override function "OnInit", then get view class and add listener.

```
CubeView _cubeView;
public override void OnInit() {
      _cubeView = View as CubeView;
      if (null == _cubeView) {
          Debug.LogError("cube view is null");
          return;
      }
      AddListener(MediatorEvent.GetScore, OnGetScore);
  }
```

### &#x20;**5.Create View**

* Create view class drive from class "HnFramework.MVC.View", e.g. "XXView" and add the script component to any ui gameobject.
* Override function "InitMediator", and bind mediator.

```
protected override void InitMediator() {
      BindMediator(typeof(CubeMediator));
  }
```

### &#x20;**6.Dispatch**

* You can call function "DispatchCommand(enum)" to make command work(e.g. get model datas) in view or mediator class.
* You can call function "DispatchMediator(enum)" to update UI in command class.
