• From the Desktop/Console or Mobile options, select your preference.

  

4. Give your project a memorable name e.g. BlockchainGame and then click Create Project

5. Check your project is successfully created and opens. Then close it. So we can do the next important step of adding the SDK.

STEP THREE - Download Mirage SDK

1. Download the latest release of MirageSDK.zip package.

2. Create a new folder (if it doesn't exist) inside the project you just created and call it Plugins.

3. Extract the downloaded MirageSDK.zip contents into the Plugins folder you just created.

4. Delete the MirageSDK.zip file if it is inside the Plugins folder as well.

STEP FOUR - Generate the Xcode project

1. Open Unreal Editor

2. If you get a notice saying "Missing BlockchainGame Modules Ankr SDK". Select Yes to rebuild.

3. It should now compile the project.

4. Once the project is compiled, select Tools > Generate Xcode project

5. When this is done, select Tools > Open Xcode

STEP FIVE - Build project

1. Inside Xcode, you should be able to see the AnkrSDK included in the Plugins folder.

2. Expand Games > your_unreal_project__name > Source > your_unreal_project_name > your_unreal_project_name.Build.cs

   

   Add "AnkrSDK" at the end of the string array as shown below:

   PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "AnkrSDK" });

3. Now from the top menu, select Product > Build For > running

4. You can view the Build status in the top right.

5. You know everything has worked out when a message appears stating 'Build Succeeded'.

STEP SIX - Open project in Unreal Editor

1. Locate GameInstance.h if already created. If not Add C++ class from Content Browser, check Show All Classes and select GameInstance. Name your class 'MyGameInstance'.

2. Open MyGameInstance.h and include the following code:

      #include "MirageClient.h"
   
      UPROPERTY()
      UMirageClient* ankrClient;
   
      UFUNCTION(BlueprintCallable, Category = "MIRAGE SDK")
      UMirageClient* GetMirageClient();

3. Open MyGameInstance.cpp and include the following code:

   UMirageClient* UMyGameInstance::GetMirageClient()
   {
      if (mirageClient == nullptr)
      {
         mirageClient = NewObject<UMirageClient>();
      }
   
      return mirageClient;
   }

4. You can now add and use all the functions from the Ankr SDK in your game.
