Public variable UProperty Category BlueprintReadOnly Config bool bShouldAlwaysTick Decides whether this trigger ticks every frame or not.
Public variable UProperty Category BlueprintReadOnly FInputActionValue LastValue Value passed to UpdateState on the previous tick. This will be updated automatically after the trigger is updated.

Functions

  Type Name Description
Public function Virtual Const FString Provide debug output for use with ShowDebug EnhancedInput. Return an empty string to disable display.
