Syntax

UCLASS (Abstract, Blueprintable, EditInlineNew, MinimalAPI)  
class UCameraShakeBase : public UObject

Remarks

Base class for a camera shake. A camera shake contains a root shake "pattern" which is the object that contains the actual logic driving how the camera is shaken. Keeping the two separate makes it possible to completely change how a shake works without having to create a completely different asset.

Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere bool bSingleInstance If true to only allow a single instance of this shake class to play at any given time.
Public variable UProperty Category BlueprintReadWrite Transient float ShakeScale The overall scale to apply to the shake. Only valid when the shake is active.

Constructors

  Type Name Description
Public function  

UCameraShakeBase ( const FObjectInitializer& ObjectInitializer
)

 Create a new instance of a camera shake

Functions

  Type Name Description
Public function Static void Applies any appropriate system-wide limits
Protected function Const void Modifies the current shake offset to be oriented in the current shake's play space (only if the result is "relative")
Public function Static void

ApplyPlaySpace ( ECameraShakePlaySpace PlaySpace,
FMatrix UserPlaySpaceMatrix,
const FMinimalViewInfo& InPOV,
FCameraShakePatternUpdateResult& InOutResult
)

 Modifies the current shake offset to be oriented in the current shake's play space (only if the result is "relative")
Public function Static void Uses the given result parameters to apply the given result to the given input view info
Public function Static void

ApplyScale ( float Scale,
FCameraShakePatternUpdateResult& InOutResult
)

 Applies the given scale to the current shake offset (only if the result is "relative")
Public function Static void Applies all the appropriate auto-scaling to the current shake offset (only if the result is "relative")
Public function ShakePatternType * Creates a new pattern of the given type and sets it as the root one on this shake
Public function Const APlayerCameraManager * Gets the current camera manager. Will be null if the shake isn't active.
Public function Static bool

GetCameraShakeBlendTimes ( TSubclassOf< UCameraShakeBase > CameraShakeClass,
float& OutBlendIn,
float& OutBlendOut
)

 Gets the default blend in/out durations for camera shakes of the given class.
Public function Const void

GetCameraShakeBlendTimes ( float& OutBlendIn,
float& OutBlendOut
)

 Gets the duration of this camera shake's blend in and out.
Public function Static bool Gets the default duration for camera shakes of the given class.
Public function Const FCameraShakeDuration Gets the duration of this camera shake in seconds.
Public function Const float  
Public function Const ECameraShakePlaySpace Returns the current play space. The value is irrelevant if the shake isn't active.
Public function Const UFunction BlueprintPure, Category UCameraShakePattern * Gets the root pattern of this camera shake
Public function Const void Gets some infromation about this specific camera shake
Public function Const const FMatrix & Returns the current play space matrix.
Public function Const bool Returns whether this shake is active.
Public function Const bool Returns whether this camera shake is finished
Public function void

ScrubAndApplyCameraShake ( float AbsoluteTime,
float Alpha,
FMinimalViewInfo& InOutPOV
)

 Scrubs this camera shake to the given time and applies its effect to the given view
Public function UFunction BlueprintCallable, Category void Sets the root pattern of this camera shake
Public function void

SetUserPlaySpaceMatrix ( const FMatrix& InMatrix
)

 Sets the current play space matrix.
Public function void Starts this camera shake with the given parameters
Public function void

StartShake ( APlayerCameraManager* Camera,
float Scale,
ECameraShakePlaySpace InPlaySpace,
FRotator UserPlaySpaceRot
)

 Starts this camera shake with the given parameters
Public function void

StopShake ( bool bImmediately
)

Public function void Tears down this camera shake before destruction or recycling
Public function void

UpdateAndApplyCameraShake ( float DeltaTime,
float Alpha,
FMinimalViewInfo& InOutPOV
