UE4 通过按键切换不同的HUD

咱们在玩游戏的时候，通常会和界面进行各种各样的互动，而且会动都是在不同的界面上，所以需要在不同的界面上进行切换或者多个HUD重叠显示在一起。
首先创建两个HUD

2.重新定义一个PlayerController类

// Fill out your copyright notice in the Description page of Project Settings.#pragma once#include "CoreMinimal.h"
#include "GameFramework/PlayerController.h"
#include "ChangeHUD/IChangeHUD.h"
#include "CameraPlayerController.generated.h"/****/
UCLASS()
class TRUEFPSPROJECT_API ACameraPlayerController : public APlayerController, public IChangeHUD {GENERATED_BODY()public:ACameraPlayerController();//编辑器内UMG资产的引用UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AAA")TSubclassOf<class UUserWidget> mainHUDAsset;//创建后用于空间变量UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AAA")UUserWidget* mainHUDMenu;//编辑器内UMG资产的引用UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AAA")TSubclassOf<class UUserWidget> subHUDAsset;//创建后用于空间变量UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = "AAA")UUserWidget* subHUDMenu;virtual void BeginPlay();virtual void changeHUD()override;
private:int32 HUDChoose = 0;//切换不同的HUD界面UUserWidget* _currentHUD = nullptr;
};

// Fill out your copyright notice in the Description page of Project Settings.#include "CameraPlayerController.h"
#include "Blueprint/UserWidget.h"
#include "ChangeHUD/ChangeHUDManager.h"ACameraPlayerController::ACameraPlayerController() {ChangeHUDMgr()->changeHUDInterface = this;
}void ACameraPlayerController::BeginPlay() {Super::BeginPlay();if (mainHUDAsset) {mainHUDMenu = CreateWidget<UUserWidget>(this, mainHUDAsset);}if (subHUDAsset) {subHUDMenu = CreateWidget<UUserWidget>(this, subHUDAsset);}
}void ACameraPlayerController::changeHUD() {if (_currentHUD) {_currentHUD->RemoveFromViewport();}HUDChoose += 1;if (HUDChoose%3 == 0){_currentHUD = mainHUDMenu;_currentHUD->AddToViewport();} else if(HUDChoose % 3 == 1) {_currentHUD = subHUDMenu;_currentHUD->AddToViewport();}else{mainHUDMenu->AddToViewport();subHUDMenu->AddToViewport();}}

定义一个接口类和接口管理类

#pragma once
class IChangeHUD {public:virtual void changeHUD() = 0;
};

#pragma once#define ChangeHUDMgr() (ChangeHUDManager::getInstance())class ChangeHUDManager {private:ChangeHUDManager();static ChangeHUDManager* _instance;
public:static ChangeHUDManager* getInstance();class IChangeHUD* changeHUDInterface;
};

#include "ChangeHUDManager.h"
#include "IChangeHUD.h"ChangeHUDManager* ChangeHUDManager::_instance = new ChangeHUDManager;ChangeHUDManager::ChangeHUDManager() {}ChangeHUDManager* ChangeHUDManager::getInstance() {return _instance;
}

在角色类中通过按键H来调用：

// Fill out your copyright notice in the Description page of Project Settings.#pragma once#include "CoreMinimal.h"
#include "GameFramework/Actor.h"
#include "SpawnActor.generated.h"UCLASS()
class TRUEFPSPROJECT_API ASpawnActor : public AActor {GENERATED_BODY()public:// Sets default values for this actor's propertiesASpawnActor();protected:// Called when the game starts or when spawnedvirtual void BeginPlay() override;public:// Called every framevirtual void Tick(float DeltaTime) override;public:UPROPERTY(EditAnywhere, Category = "AAA")TSubclassOf<class AFloatingActor> subFloatingActor;float baseTime = 0.0;
};

// Fill out your copyright notice in the Description page of Project Settings.#include "SpawnActor.h"
#include "FloatingActor.h"// Sets default values
ASpawnActor::ASpawnActor() {// Set this actor to call Tick() every frame.  You can turn this off to improve performance if you don't need it.PrimaryActorTick.bCanEverTick = true;}// Called when the game starts or when spawned
void ASpawnActor::BeginPlay() {Super::BeginPlay();}// Called every frame
void ASpawnActor::Tick(float DeltaTime) {Super::Tick(DeltaTime);if ((baseTime += DeltaTime) <= 3.0){return;}baseTime = 0.0;UWorld* world = GetWorld();if (world){FVector spawnLocation = GetActorLocation();FRotator spwanRotation = GetActorRotation();FActorSpawnParameters spawnParam;spawnParam.SpawnCollisionHandlingOverride = ESpawnActorCollisionHandlingMethod::AdjustIfPossibleButDontSpawnIfColliding;world->SpawnActor<AFloatingActor>(subFloatingActor, spawnLocation, spwanRotation, spawnParam);}
}
