⚙️ 3. Installation:

1. In this Github repository, clone this repo with git command or download as a zip file type and rename cloned folder name AlgorandUnrealEngineSDK.
2. You can find a folder called example, which is our test project.
3. Then you should create a folder called Plugins/Algorand on example/unreal-algorand-demo folder.
4. You should copy all except for example folder on AlgorandUnrealEngineSDK folder to the Plugins/Algorand folder of our test project.

After you complete above action, this plugin path is example\unreal-algorand-demo\Plugins\Algorand.

5. You should register the plugin name (Algorand) into Build.cs on the Source directory of out test project (example\unreal-algorand-demo) and rebuild your project.

   public UnrealAlgorandPlugin(ReadOnlyTargetRules Target) : base(Target)
   {
       PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
       
       PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "Algorand" });
   
       PrivateDependencyModuleNames.AddRange(new string[] {  });
   }
   

Right click on UnrealAlgorandPlugin.uproject on example/unreal-algorand-demo folder, and "Generate Visual Studio project files" - This process may take some time.

6. Once finished, open your *.sln project or *.uproject file with Visual Studio or JetBrains Rider.
