一，子弹类型
// .h文件 #include "CoreMinimal.h" #include "GameFramework/Actor.h" #include "Components/SphereComponent.h" #include "GameFrameWork/ProjectileMovementComponent.h" #include "MyActor.generated.h" // ... UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UStaticMeshComponent> Sphere; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<USphereComponent> SphereCollision; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UProjectileMovementComponent> ProjectileMovement;
// .cpp文件 AMyActor::AMyActor() { PrimaryActorTick.bCanEverTick = true; Sphere = CreateDefaultSubobject<UStaticMeshComponent>(TEXT("Sphere")); SphereCollision = CreateDefaultSubobject<USphereComponent>(TEXT("SphereCollision")); ProjectileMovement = CreateDefaultSubobject<UProjectileMovementComponent>(TEXT("ProjectileMovement")); static ConstructorHelpers::FObjectFinder<UStaticMesh> StaticSphereMesh(TEXT("/Engine/BasicShapes/Sphere.Sphere")); RootComponent = Sphere; SphereCollision->SetupAttachment(RootComponent); ProjectileMovement->SetUpdatedComponent(RootComponent); Sphere->SetStaticMesh(StaticSphereMesh.Object); ProjectileMovement->InitialSpeed = 500.0; ProjectileMovement->MaxSpeed = 2000.0; }
二，带有增强输入的角色类型
// .h文件 #include "CoreMinimal.h" #include "InputActionValue.h" #include "EnhancedInputComponent.h" #include "EnhancedInputSubsystems.h" #include "GameFramework/Controller.h" #include "GameFramework/SpringArmComponent.h" #include "Camera/CameraComponent.h" #include "GameFramework/Character.h" #include "GameFramework/CharacterMovementComponent.h" #include "MyCharacter.generated.h" class UInputAction; class UInputMappingContext; // ... public: UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<USpringArmComponent> SpringArm; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UCameraComponent> Camera; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UInputMappingContext> DefaultMappingContext; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UInputAction> MoveAction; UPROPERTY(EditAnywhere, BlueprintReadWrite) TObjectPtr<UInputAction> LookAction; public: void Move(const FInputActionValue& value); void Look(const FInputActionValue& value); // ...
// .cpp文件 AMyCharacter::AMyCharacter() { PrimaryActorTick.bCanEverTick = true; SpringArm = CreateDefaultSubobject<USpringArmComponent>(TEXT("SpringArm")); Camera = CreateDefaultSubobject<UCameraComponent>(TEXT("Camera")); SpringArm->TargetArmLength = 400.0f; SpringArm->bUsePawnControlRotation = true; SpringArm->SetupAttachment(RootComponent); Camera->SetupAttachment(SpringArm); //控制器只影响相机不影响角色 bUseControllerRotationPitch = false; bUseControllerRotationRoll = false; bUseControllerRotationYaw = false; GetCharacterMovement()->bOrientRotationToMovement = true; } void AMyCharacter::BeginPlay() { Super::BeginPlay(); if (auto PlayerController = Cast<APlayerController>(Controller)) if (auto Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(PlayerController->GetLocalPlayer())) Subsystem->AddMappingContext(DefaultMappingContext, 0); } void AMyCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) { Super::SetupPlayerInputComponent(PlayerInputComponent); if (auto EnhancedInputComponent = CastChecked<UEnhancedInputComponent>(PlayerInputComponent)) { EnhancedInputComponent->BindAction(MoveAction, ETriggerEvent::Triggered, this, &AMyCharacter::Move); EnhancedInputComponent->BindAction(LookAction, ETriggerEvent::Triggered, this, &AMyCharacter::Look); } } void AMyCharacter::Move(const FInputActionValue& value) { FVector2D MovementVector = value.Get<FVector2D>(); if (Controller) { const FRotator Rotation = Controller->GetControlRotation(); const FRotator YawRotation(0, Rotation.Yaw, 0); const FVector FowardDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::X); const FVector RightDirection = FRotationMatrix(YawRotation).GetUnitAxis(EAxis::Y); AddMovementInput(FowardDirection, MovementVector.Y); AddMovementInput(RightDirection, MovementVector.X); } } // 5.7使用IMC_Default 和 IMC_MouseLook 将按键和鼠标操作分开 // IMC_Default → 按键操作（移动、跳跃、冲刺、交互等） // IMC_MouseLook → 鼠标操作（视角旋转） void AMyCharacter::Look(const FInputActionValue& value) { FVector2D LookAxisVector = value.Get<FVector2D>(); if (Controller) { AddControllerYawInput(LookAxisVector.X); AddControllerPitchInput(LookAxisVector.Y); } }
