Public Methods¶

Return	Name	Description
	`UComposableCameraDirector`
`AComposableCameraCameraBase *`	`ResumeCamera`
`AComposableCameraCameraBase *`	`CreateNewCamera`
`AComposableCameraCameraBase *`	`ActivateNewCamera`
`AComposableCameraCameraBase *`	`ActivateNewCamera`	Activate a new camera using a raw transition instance (not wrapped in a DataAsset). Used by ActivateNewCameraFromTypeAsset when the type asset provides its own DefaultTransition as an instanced UComposableCameraTransitionBase*. The transition is duplicated into the Director's context before use.
`AComposableCameraCameraBase *`	`ActivateNewCameraWithReferenceSource`	Activate a new camera with a reference to another Director as the transition source. Used for inter-context transitions: the reference leaf evaluates the source Director live.
`AComposableCameraCameraBase *`	`ActivateNewCameraWithReferenceSource`	Inter-context activation using a raw transition instance. Used by ActivateNewCameraFromTypeAsset when the type asset provides a DefaultTransition.
`AComposableCameraCameraBase *`	`ReactivateCurrentCamera`
`FComposableCameraPose`	`Evaluate`
`AComposableCameraCameraBase *`	`GetRunningCamera` `const` `inline`	Get the currently running (target) camera in this Director's evaluation tree.
`const FComposableCameraPose &`	`GetLastEvaluatedPose` `const` `inline`	Get the last evaluated (blended) pose from this Director.
`const FComposableCameraPose &`	`GetPreviousEvaluatedPose` `const` `inline`	Get the previous frame's evaluated (blended) pose from this Director.
`void`	`DestroyAllCameras`	Destroy all cameras in this Director's evaluation tree. Called when a context is popped.
`void`	`BuildDebugString` `const`	Build a debug string showing this Director's evaluation tree.

UComposableCameraDirector¶

UComposableCameraDirector(const FObjectInitializer & ObjectInitializer)

ResumeCamera¶

AComposableCameraCameraBase * ResumeCamera(AComposableCameraCameraBase * ResumeCamera, UComposableCameraTransitionBase * Transition, const FTransform & Transform)

CreateNewCamera¶

AComposableCameraCameraBase * CreateNewCamera(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, const FComposableCameraActivateParams & ActivationParams)

ActivateNewCamera¶

AComposableCameraCameraBase * ActivateNewCamera(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, UComposableCameraTransitionDataAsset * TransitionDataAsset, const FComposableCameraActivateParams & ActivationParams, FOnCameraFinishConstructed OnPreBeginplayEvent)

ActivateNewCamera¶

AComposableCameraCameraBase * ActivateNewCamera(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, UComposableCameraTransitionBase * TransitionInstance, const FComposableCameraActivateParams & ActivationParams, FOnCameraFinishConstructed OnPreBeginplayEvent)

Activate a new camera using a raw transition instance (not wrapped in a DataAsset). Used by ActivateNewCameraFromTypeAsset when the type asset provides its own DefaultTransition as an instanced UComposableCameraTransitionBase*. The transition is duplicated into the Director's context before use.

ActivateNewCameraWithReferenceSource¶

AComposableCameraCameraBase * ActivateNewCameraWithReferenceSource(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, UComposableCameraTransitionDataAsset * TransitionDataAsset, const FComposableCameraActivateParams & ActivationParams, FOnCameraFinishConstructed OnPreBeginplayEvent, UComposableCameraDirector * SourceDirector, UComposableCameraTransitionBase ** OutTransition)

Activate a new camera with a reference to another Director as the transition source. Used for inter-context transitions: the reference leaf evaluates the source Director live.

ActivateNewCameraWithReferenceSource¶

AComposableCameraCameraBase * ActivateNewCameraWithReferenceSource(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, UComposableCameraTransitionBase * TransitionInstance, const FComposableCameraActivateParams & ActivationParams, FOnCameraFinishConstructed OnPreBeginplayEvent, UComposableCameraDirector * SourceDirector)

Inter-context activation using a raw transition instance. Used by ActivateNewCameraFromTypeAsset when the type asset provides a DefaultTransition.

ReactivateCurrentCamera¶

AComposableCameraCameraBase * ReactivateCurrentCamera(AComposableCameraPlayerCameraManager * PlayerCameraManager, TSubclassOf< AComposableCameraCameraBase > CameraClass, UComposableCameraTransitionBase * Transition, const FOnCameraFinishConstructed & OnPreBeginplayEvent)

Evaluate¶

Get the currently running (target) camera in this Director's evaluation tree.

GetLastEvaluatedPose¶

const inline

inline const FComposableCameraPose & GetLastEvaluatedPose() const

Get the last evaluated (blended) pose from this Director.

GetPreviousEvaluatedPose¶

const inline

inline const FComposableCameraPose & GetPreviousEvaluatedPose() const
