這一篇是進行玩家移動和視角移動的介紹。

1.在玩家內進行移動覆寫

virtual void SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) override;

2.創建增強輸入資產的變量創建

UPROPERTY(EditDefaultsOnly, BlueprintReadOnly, Category = "CharacterData", meta = (AllowPrivateAccess = "true"))UDA_InputConfig* InputConfigDataAsset;

3.進行移動和視角移動函數的創建

void Input_Move(const FInputActionValue& InputActionValue);void Input_Look(const FInputActionValue& InputActionValue);

4.在SetupPlayerInputComponent函數內進行輸入綁定

//設置玩家輸入組件
void AXMBCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{//添加映射上下文checkf(InputConfigDataAsset, TEXT("Forgot to assign a valid data as input config"))//獲取本地玩家ULocalPlayer* LocalPlayer = GetController<APlayerController>()->GetLocalPlayer();//獲取增強輸入子系統UEnhancedInputLocalPlayerSubsystem* Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(LocalPlayer);check(Subsystem);//添加映射上下文Subsystem->AddMappingContext(InputConfigDataAsset->DefaultMappingContext,0);//獲取角色輸入組件并綁定輸入動作UXMBWarriorInputComponent* WarriorInputComponent = CastChecked<UXMBWarriorInputComponent>(PlayerInputComponent);WarriorInputComponent->BindNativeInputAction(InputConfigDataAsset,XMBGameplayTags::InputTag_Move, ETriggerEvent::Triggered,this,&ThisClass::Input_Move);WarriorInputComponent->BindNativeInputAction(InputConfigDataAsset,XMBGameplayTags::InputTag_Look, ETriggerEvent::Triggered,this,&ThisClass::Input_Look);}

5.對Move函數進行設置

void AXMBCharacter::Input_Move(const FInputActionValue& InputActionValue)
{//獲取移動向量const FVector2D MovementVector = InputActionValue.Get<FVector2D>();//獲取移動旋轉const FRotator MovementRotation(0.f, Controller->GetControlRotation().Yaw, 0.f);//處理前后移動if (MovementVector.Y != 0.f){const FVector ForwardDirection = MovementRotation.RotateVector(FVector::ForwardVector);AddMovementInput(ForwardDirection, MovementVector.Y);}//處理左右移動if (MovementVector.X != 0.f){const FVector RightDirection = MovementRotation.RotateVector(FVector::RightVector);AddMovementInput(RightDirection, MovementVector.X);}}

6.對視角移動函數進行設置

void AXMBCharacter::Input_Look(const FInputActionValue& InputActionValue)
{const FVector2D LookAxisVector = InputActionValue.Get<FVector2D>();if (LookAxisVector.X != 0.f){AddControllerYawInput(LookAxisVector.X);}if (LookAxisVector.Y != 0.f){AddControllerPitchInput(LookAxisVector.Y);}
}

7.打開引擎，進入角色藍圖，細節面板搜索data，更換成自己的dataasset

{Super::BeginPlay();Debug::Print(FString::Printf(TEXT("XMBCharacter::BeginPlay")));
}//設置玩家輸入組件
void AXMBCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{//添加映射上下文checkf(InputConfigDataAsset, TEXT("Forgot to assign a valid data as input config"))//獲取本地玩家ULocalPlayer* LocalPlayer = GetController<APlayerController>()->GetLocalPlayer();//獲取增強輸入子系統UEnhancedInputLocalPlayerSubsystem* Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(LocalPlayer);check(Subsystem);//添加映射上下文Subsystem->AddMappingContext(InputConfigDataAsset->DefaultMappingContext,0);//獲取角色輸入組件并綁定輸入動作UXMBWarriorInputComponent* WarriorInputComponent = CastChecked<UXMBWarriorInputComponent>(PlayerInputComponent);WarriorInputComponent->BindNativeInputAction(InputConfigDataAsset,XMBGameplayTags::InputTag_Move, ETriggerEvent::Triggered,this,&ThisClass::Input_Move);WarriorInputComponent->BindNativeInputAction(InputConfigDataAsset,XMBGameplayTags::InputTag_Look, ETriggerEvent::Triggered,this,&ThisClass::Input_Look);}void AXMBCharacter::Input_Move(const FInputActionValue& InputActionValue)

{const FVector2D LookAxisVector = InputActionValue.Get<FVector2D>();if (LookAxisVector.X != 0.f){AddControllerYawInput(LookAxisVector.X);}if (LookAxisVector.Y != 0.f){AddControllerPitchInput(LookAxisVector.Y);}
