Functions

  Type Name Description
Public function void

Initialize ( float InWindowDuration,
EFilterInterpolationType InInterpolationType,
float InDampingRatio,
float InMinValue,
float InMaxValue,
float InMaxSpeed,
bool bInClamp
)

  
Public function Const bool

IsValid ()

 Filter is considered valid if the WindowDuration is > 0.
Public function bool

NeedsUpdate ( const EFilterInterpolationType InType,
const float InWindowDuration
)

  
Public function void

SetParams ( float InDampingRatio,
float InMinValue,
float InMaxValue,
float InMaxSpeed,
bool bInClamp
)

 These parameters can be modified at runtime without needing to re-initialize.
Public function void

SetToValue ( float Input
)

 Sets internal state to the specified value.
Public function void

SetWindowDuration ( float InWindowDuration
)

  
Public function float

UpdateAndGetFilteredData ( float Input,
float DeltaTime
)

 This adds Input to the stack representing an update of DeltaTime, and returns the new filtered value.
Public function void

WrapToValue ( float Input,
float Range
)

 Wraps the internal state by steps of Range so that it is as close as possible to Input.
