这一篇是进行玩家移动和视角移动的介绍。

1.在玩家内进行移动覆写

virtual void SetupPlayerInputComponent(UInputComponent* PlayerInputComponent) override;

2.创建增强输入资产的变量创建

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

3.进行移动和视角移动函数的创建

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

4.在SetupPlayerInputComponent函数内进行输入绑定

//设置玩家输入组件
void AXMBCharacter::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
{//添加映射上下文checkf(InputConfigDataAsset, TEXT("Forgot to assign a valid data as input config"))//获取本地玩家ULocalPlayer* LocalPlayer = GetController<APlayerController>()->GetLocalPlayer();//获取增强输入子系统UEnhancedInputLocalPlayerSubsystem* Subsystem = ULocalPlayer::GetSubsystem<UEnhancedInputLocalPlayerSubsystem>(LocalPlayer);check(Subsystem);//添加映射上下文Subsystem->AddMappingContext(InputConfigDataAsset->DefaultMappingContext,0);//获取角色输入组件并绑定输入动作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.对Move函数进行设置

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

6.对视角移动函数进行设置

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.打开引擎，进入角色蓝图，细节面板搜索data，更换成自己的dataasset

}//设置玩家输入组件

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