Program Code – C++ For Unreal Engine: Developing Games with Unreal

#include 'MyGameModeBase.h'
#include 'Engine/World.h'
#include 'TimerManager.h'
#include 'MyCharacter.h'

AMyGameModeBase::AMyGameModeBase()
{
    PrimaryActorTick.bCanEverTick = true;
    // Set default pawn class to our Blueprinted character
    static ConstructorHelpers::FClassFinder<APawn> PlayerPawnBPClass(TEXT('/Game/ThirdPersonCPP/Blueprints/ThirdPersonCharacter'));
    if (PlayerPawnBPClass.Class != nullptr)
    {
        DefaultPawnClass = PlayerPawnBPClass.Class;
    }
}

void AMyGameModeBase::BeginPlay()
{
    Super::BeginPlay();
    ChangeMenuWidget(StartingWidgetClass);
    // Start the game with a countdown
    GetWorld()->GetTimerManager().SetTimer(GameStartTimerHandle, this, &AMyGameModeBase::StartGame, CountdownTime, false);
}

void AMyGameModeBase::Tick(float DeltaSeconds)
{
    Super::Tick(DeltaSeconds);
    // Game logic goes here
}

void AMyGameModeBase::ChangeMenuWidget(TSubclassOf<UUserWidget> NewWidgetClass)
{
    if (CurrentWidget)
    {
        CurrentWidget->RemoveFromViewport();
        CurrentWidget = nullptr;
    }
    if (NewWidgetClass)
    {
        CurrentWidget = CreateWidget<UUserWidget>(GetWorld(), NewWidgetClass);
        if (CurrentWidget)
        {
            CurrentWidget->AddToViewport();
        }
    }
}

void AMyGameModeBase::StartGame()
{
    // Trigger in-game events to officially start
}

Code Output:

The code does not produce a visible output as it is designed to set up the game mode for an Unreal Engine game. Instead, it will initialize the game mode with the specified player character, manage the game state transition from the starting widget to the actual game, and handle the game start after a countdown.

Code Explanation:

• Import the required headers needed for the game mode, including the UE4 framework classes ‘World’ and ‘TimerManager,’ and the custom character class ‘MyCharacter.’
• In the constructor ‘AMyGameModeBase::AMyGameModeBase()’, set PrimaryActorTick to enable ticking for this actor, which allows for repeated actions frame by frame. It also finds the player pawn Blueprint class and sets it as the default pawn class if found.
• The method ‘BeginPlay()’ is called when the game starts. It calls ‘ChangeMenuWidget’ to display the initial game’s UI and sets a timer for the game start event with ‘StartGame’ method delegate as its callback.
• ‘Tick()’ is overridden to implement continuous game logic that runs every frame.
• ‘ChangeMenuWidget()’ is a utility method used to change the UI widget displayed on the screen.
• ‘StartGame()’ is a placeholder for logic to initiate actual game play.

This game mode setup is foundational for a game in Unreal Engine, showcasing the setup of initial game state and transition to the game play state. The real complexity comes when you implement the game logic inside Tick() and StartGame() functions, and through interactions with other game classes and systems.
