UE4 关卡HUD显示方法两种

方法一

在蓝图关卡中将蓝图控件添加到视口：

方法二

在PlayerController类中创建并添加到视口：

#pragma once

#include "CoreMinimal.h"
#include "GameFramework/PlayerController.h"
#include "TPSPlayerController.generated.h"


UCLASS()
class NETEASETPS_API ATPSPlayerController : public APlayerController
{
	GENERATED_BODY()

public:
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	TSubclassOfHUDAssert;

	UUserWidget* HUD;

protected:
	virtual void BeginPlay() override;

};

#include "TPSPlayerController.h"

#include "Blueprint/UserWidget.h"


void ATPSPlayerController::BeginPlay()
{
	Super::BeginPlay();

	if (HUDAssert)
	{
		HUD = CreateWidget(this, HUDAssert);
	}

	if (HUD)
	{
		HUD->AddToViewport();
	}
}

然后新建PlayerController子类蓝图并指定控件蓝图，在世界场景中指定该PlayerController蓝图类。
