Create Player Controller and Game Mode Classes #

In this section, we’ll create the C++ player controller and game mode classes, and associated Blueprints.

Prerequisites:

• Set Up the Unreal SDK

Create C++ files #

In your Unreal Editor create the following C++ classes.

• a MyPlayerController class with a “Player Controller” parent
• a MyGameModeBase class with a “Game Mode Base” parent

Create Unreal Blueprints #

After the player controller and game mode base files are created, create the following two Blueprint classes, one based on the player controller, and one based on the game mode. We recommend saving these Blueprint classes in a new directory dedicated to Blueprints.

• a MyPlayerControllerBP Blueprint based on MyPlayerController
• a MyGameModeBaseBP Blueprint based on MyGameModeBase. Set the GameModeBaseBP’s Player Controller Class to MyPlayerControllerBP.

Set up the player controller files #

1. Add the following code to your MyPlayerController.h header file.

   #pragma once
   
   #include "CoreMinimal.h"
   #include "GameFramework/PlayerController.h"
   #include "PragmaPtr.h"
   #include "Dto/PragmaPartyRpcExtDto.h"
   #include "MyPlayerController.generated.h"
   
   // Forward declares Pragma pointer types for Pragma::FPlayer.
   PRAGMA_FWD(FPlayer);
   
   UCLASS()
   class UNREALTUTORIAL_API AMyPlayerController : public APlayerController
   {
       GENERATED_BODY()
   
   public:
       //Called when Unreal level is loaded
       virtual void BeginPlay() override;
   
   private:
       // Pointer to our Pragma Player owned by the PRagmaLocalPlayerSubsystem.
       Pragma::FPlayerPtr Player;
   }
   

2. Add the following code to your MyPlayerController.cpp source file:

   #include "MyPlayerController.h"
   #include "PragmaPlayer.h"
   #include "PragmaLocalPlayerSubsystem.h"
   
   void AMyPlayerController::BeginPlay()
   {
       Super::BeginPlay();
   
       UE_LOG(LogTemp, Display, TEXT("MyGameClient -- Game client startup."));
   
       const auto* Subsystem = GetLocalPlayer()
           ->GetSubsystem<UPragmaLocalPlayerSubsystem>();
       Player = Subsystem->Player();
   }
   

Hook up player controller to a new level #

1. Ensure Pragma Engine is running.

2. Compile and open the Unreal project from your IDE.

3. Hook up the new MyPlayerController class as the default Player Controller for your game mode and level:

   a. Right click in the Content panel, create a new Level, and open that level. (Just so we don’t edit any of your existing levels.)

   b. Open the Window menu and click World Settings.

   c. In the World Settings panel under Game Mode click the GameMode Override dropdown and select the MyGameModeBaseBP option.

   d. In the World Settings panel under Game Mode ensure the Player Controller Class is set to MyPlayerControllerBP.

Next steps #

You now have a basic Unreal project with all the items needed to begin integrating Pragma features. In the next topic we’ll add login and logout functionality using the player controller classes and Pragma SDK.
