+## 调试命令
+- showdebug enhancedinput：会显示你的项目的可用输入动作和轴映射。
+- showdebug devices
+
+# 相关类
+- **Input Actions**：配置输入动作 => 数据或者状态用的资产。
+- **Input Mapping Contexts**：输入Action的集合。可以为不同GameMode配置不同的 **Input Mapping Contexts**来满足自定义输入的需求。
+- **Input Modifiers**： 是一种预处理器，能够修改UE接收的原始输入值，然后再将其发送给输入触发器（Input Trigger）。增强输入插件随附多种输入修饰器，可以执行各种任务，例如更改轴顺序、实现"死区"、将轴输入转换为世界空间。
+- **Input Triggers**：用于确定用户输入在经过一系列可选输入修饰器的处理后，是否会激活输入映射上下文中的相应输入动作。
+- 多平台相关：位于Project Settings -> Enhanced Input -> Platform Settings -> Input Data
+	- Mapping Context Redirect：将不同的输入设置用于不同的平台。
+	- Enhanced Input Platform Data：为你的游戏添加特定于平台的选项。
+
+**InputAction**绑定:
+```c++
+void AFooBar::SetupPlayerInputComponent(UInputComponent* PlayerInputComponent)
+{
+	UEnhancedInputComponent* Input = Cast<UEnhancedInputComponent>(PlayerInputComponent);
+	// 你可以通过更改"ETriggerEvent"枚举值，绑定到此处的任意触发器事件
+	Input->BindAction(AimingInputAction, ETriggerEvent::Triggered, this, &AFooBar::SomeCallbackFunc);
+}
+ 
+void AFooBar::SomeCallbackFunc(const FInputActionInstance& Instance)
+{
+	// 获取此处所需任意类型的输入动作的值...
+	FVector VectorValue = Instance.GetValue().Get<FVector>();
+	FVector2D 2DAxisValue = Instance.GetValue().Get<FVector2D>();
+	float FloatValue = Instance.GetValue().Get<float>(); 
+	bool BoolValue = Instance.GetValue().Get<bool>();
+ 
+	// 在此处实现你的精彩功能！
+} 
+```
+
+Runtime **InputMappingContext**添加：
+```c++
+// 将映射上下文公开为头文件中的属性...
+UPROPERTY(EditAnywhere, Category="Input")
+TSoftObjectPtr<UInputMappingContext> InputMapping;
+ 
+// 在你的cpp中...
+if (ULocalPlayer* LocalPlayer = Cast<ULocalPlayer>(Player))
+{
+	if (UEnhancedInputLocalPlayerSubsystem* InputSystem = LocalPlayer->GetSubsystem<UEnhancedInputLocalPlayerSubsystem>())
+	{
+		if (!InputMapping.IsNull())
+		{
+			InputSystem->AddMappingContext(InputMapping.LoadSynchronous(), Priority);
+		}
+	}
+}
+```
+
+**Input Trigger Timed Base** 会检查输入是否已被按住一段时间，如是，则接受该输入并返回 **持续（Ongoing）** 状态。
+```c++
+/** UInputTriggerHold
+	触发器会在输入保持激活状态达到HoldTimeThreshold秒之后触发。
+	触发器可以选择触发一次或反复触发。
+*/
+UCLASS(NotBlueprintable, MinimalAPI, meta = (DisplayName = "Hold"))
+class UInputTriggerHold final : public UInputTriggerTimedBase
+{
+	GENERATED_BODY()
+
+	bool bTriggered = false;
+
+protected:
+
+	virtual ETriggerState UpdateState_Implementation(const UEnhancedPlayerInput* PlayerInput, FInputActionValue ModifiedValue, float DeltaTime) override;
+
+public:
+	virtual ETriggerEventsSupported GetSupportedTriggerEvents() const override { return ETriggerEventsSupported::Ongoing; }
+	
+	// 输入要保持多久才能导致触发？
+	UPROPERTY(EditAnywhere, Config, BlueprintReadWrite, Category = "Trigger Settings", meta = (ClampMin = "0"))
+	float HoldTimeThreshold = 1.0f;
+
+	// 此触发器应该仅触发一次，还是在满足保持时间阈值之后每帧触发？
+	UPROPERTY(EditAnywhere, Config, BlueprintReadWrite, Category = "Trigger Settings")
+	bool bIsOneShot = false;
+
+	virtual FString GetDebugState() const override { return HeldDuration ? FString::Printf(TEXT("Hold:%.2f/%.2f"), HeldDuration, HoldTimeThreshold) : FString(); }
+};
+
+ETriggerState UInputTriggerHold::UpdateState_Implementation(const UEnhancedPlayerInput* PlayerInput, FInputActionValue ModifiedValue, float DeltaTime)
+{
+	// 更新HeldDuration并派生基础状态
+	ETriggerState State = Super::UpdateState_Implementation(PlayerInput, ModifiedValue, DeltaTime);
+
+	// 在HeldDuration达到阈值时触发
+	bool bIsFirstTrigger = !bTriggered;
+	bTriggered = HeldDuration >= HoldTimeThreshold;
+	if (bTriggered)
+	{
+		return (bIsFirstTrigger || !bIsOneShot) ? ETriggerState::Triggered : ETriggerState::None;
+	}
+
+	return State;
+} 
+```
