Functions

  Type Name Description
Public function bool

Equals ( const float& InA,
const float& InB,
double InTolerance
)

  
Public function bool

Equals ( const double& InA,
const double& InB,
double InTolerance
)

  
Public function Static bool

Equals ( const NumericType& InA,
const NumericType& InB,
double InTolerance
)

 Helper function to compare to values - to allow to specialize per type as needed
Public function Const const NumericType &

Get ()

 Returns the interpolated value
Public function Const double Returns the delta time between the start of the animation and now
Public function Const bool

IdenticalTo ( const TAttributeInterpolator* InOther
)

 Compares this interpolator to another one
Protected function Const void Interpolates the internal value against the new value This method is expected to set the Value member
Public function Const bool Returns true if the interpolator is enabled
Protected function Const bool Returns true if this interpolator is currently playing.
Public function Const bool

IsSet ()

 Returns true if this interpolator's value has even been set
Public function Const bool Returns true if the interpolator is of a given type
Public function FInterpolatorEvent & Returns the delegate to react to the interpolator starting to interpolate
Public function FInterpolatorEvent & Returns the delegate to react to the interpolator ending to interpolate
Protected function Virtual Const bool  
Public function Const void

Reset ()

 Resets the interpolator
Protected function Virtual Const bool

Restart ()

 Restart the animation
Public function Const void

SetDelayOneShot ( float InDelay
)

 Sets the delay for the next shot - delays are consumed and only used once
Public function void

SetEnabled ( bool InEnabled
)

 Enables (or disables) the interpolator
Public function void

SetTolerance ( float InTolerance
)

 Sets the tolerance on this interpolator
Public function Const void

SetValue ( const NumericType& InValue
)

 Set the internal state of the interpolator
Public function Const void

SetValueAndStop ( const NumericType& InValue
)

 Set the internal state of the interpolator and disables animation
Protected function Virtual Const bool

Start ()

 Starts the animation and records time.
Protected function Virtual Const bool

Stop ()

 Stops the animation and stops recording time.
Public function void

Tick ( float InDeltaTime
)

 Updates the interpolator
