4 Connect your game with the HMS Manager

In order for the plugin to work, you need to deploy HMSManager prefab inside your scene.

1. In Unity's project view, locate the plugins prefab folder
2. Drag and drop the HMS Manager to your scene
3. Select the HMS Manager object in the hierarchy view
4. Configure the HMS Manager by selecting it and filling out the field in the Inspector
   • Key: Input your game's key
   • Set your game's products
     • Input the amount of products you created at developer's portal
     • Fill out the productID with the products ID you set on the developer's portal
     • Check the is Consumable checkbox if your product is consumable

Now you need your game to call the HMSManager from your game. You can do this by code or as a UI event. See below for further instructions.

Call the HMS by code

First, get the reference to the HMSManager

private HMSManager hmsManager =  GameObject.Find("HMSManager").GetComponent<HMSManager>();

Account Kit (login)

Call login method in order to open the login dialog

hmsManager.Login();

In App Purchases

You can retrieve a products information from App Gallery:

• Name
• Description
• Price

GetProductDetail(string productID);

Open the Purchase dialog by calling to BuyProduct method

BuyProduct(string productID)

Call the HMS from your UI

1. Select you button and open the inspector
2. Find the On Click () section and drag and drop the HMS Manager object to the object selector
3. Select the method you want to call from the dropdown list:
   • Login

If you are not sure how to do this, search the demo folder and open the sample scene.

5 Connect the HMS Callbacks Handler with you game

The Callbacks Handler is a component inside the HMS Manager that will help you deal with all the responses from HMS Servers.

1. Open the HMSCallbacksHandler.cs file inside Plugins/HuaweiMbileServices/Scripts This script is divided in two parts. The products help methods and the event methods:

   Products Help

   Gives you information about the products registered inside App Gallery Connect. Call them when needed.

   public List GetProductList(){}
   
   public string GetProductName(string productID) {}
   
   public string GetProductDescription(string productID) {}
   
   public string GetProductPrice(string productID){}

   Event Methods

   Are the methods fired when an answer arrives form server. Override or implement these to make your game respond to successfull or error callbacks. (i.e: add 100 golden coins to player when On Purchase Success event is received )

   Login

   public void OnLoginSuccess ( GameUserData gameUserData ){}
   
   public void OnLoginError ( int resultCode ){}

   Product's Details

   public void OnProductDetailSuccess ( ProductDetailsResponse response )
   public void OnProductDetailError ( int resultCode )

   Buying a Product

   public void OnPurchaseSuccess ( ProductPayReponse response )
   
   public void OnPurchaseError (int resultCode)
