+# 暂时需要使用GAS默认的枚举绑定Input的理由
+GameplayAbilitySpec.h的InputPressed：
+```c++
+UPROPERTY(NotReplicated)  
+uint8 InputPressed:1;
+```
+
+该变量用于本地输入判断，可以使用自己的代码代替，但涉及到以下几个函数，工作量比较大。
+- UAbilitySystemComponent
+	- AbilityLocalInputReleased
+	- AbilitySpecInputPressed
+	- InternalServerTryActivateAbility
+	- InternalTryActivateAbility
+	- TryActivateAbility
+	- 间接关系
+		- BindAbilityActivationToInputComponent
+		- SetBlockAbilityBindingsArray
+		- PressInputID
+		- ReleaseInputID
+- UAbilityTask_WaitInputPress
+- UAbilityTask_WaitInputRelease
+
+理论上是可以将其修改成增强输入的版本，只需要将枚举循环改成InputActionContext循环即可。

 李兄是在状态机每个节点的StateBegin()中调用CreateDynamicSkillInputActionMappingContext()进行动态绑定的。FSDHSkillInputActionBinding里包含FEnhancedActionKeyMapping相关数据。
