Class CinemachineMixingCamera

CinemachineMixingCamera is a "manager camera" that takes on the state of the weighted average of the states of its child virtual cameras.

A fixed number of slots are made available for cameras, rather than a dynamic array. We do it this way in order to support weight animation from the Timeline. Timeline cannot animate array elements.

Fields

MaxCameras

The maximum number of tracked cameras. If you want to add more cameras, do it here in the source code, and be sure to add the extra member variables and to make the appropriate changes in GetWeight() and SetWeight(). The inspector will figure itself out based on this value.

Properties

Description

Gets a brief debug description of this virtual camera, for use when displaying debug info

Declaration
public override string Description { get; }
Property Value
Type Description
string
Overrides

State

The CameraState object holds all of the information necessary to position the Unity camera. It is the output of this class.

Declaration
public override CameraState State { get; }
Property Value
Type Description
CameraState
Overrides

Methods

ChooseCurrentCamera(Vector3, float)

Choose the appropriate current camera from among the ChildCameras, based on current state. If the returned camera is different from the current camera, an appropriate transition will be made.

Declaration
protected override CinemachineVirtualCameraBase ChooseCurrentCamera(Vector3 worldUp, float deltaTime)
Parameters
Type Name Description
Vector3 worldUp

Default world Up, set by the CinemachineBrain
float deltaTime

Delta time for time-based effects (ignore if less than or equal to 0)
Returns
Type Description
CinemachineVirtualCameraBase

The current child camera that should be active. Must be present in ChildCameras.
Overrides

GetWeight(int)

Get the weight of the child at an index.

Declaration
public float GetWeight(int index)
Parameters
Type Name Description
int index

The child index. Only immediate CinemachineVirtualCameraBase children are counted.
Returns
Type Description
float

The weight of the camera. Valid only if camera is active and enabled.

GetWeight(CinemachineVirtualCameraBase)

Get the weight of the child CinemachineVirtualCameraBase.

Declaration
public float GetWeight(CinemachineVirtualCameraBase vcam)
Parameters
Type Name Description
CinemachineVirtualCameraBase vcam

The child camera.
Returns
Type Description
float

The weight of the camera. Valid only if camera is active and enabled.

InternalUpdateCameraState(Vector3, float)

Internal use only. Do not call this method. Called by CinemachineCore at designated update time so the vcam can position itself and track its targets. This implementation updates all the children, chooses the best one, and implements any required blending.

Declaration
public override void InternalUpdateCameraState(Vector3 worldUp, float deltaTime)
Parameters
Type Name Description
Vector3 worldUp

Default world Up, set by the CinemachineBrain
float deltaTime

Delta time for time-based effects (ignore if less than or equal to 0)
Overrides

IsLiveChild(ICinemachineCamera, bool)

Check whether the cam is a live child of this camera.

Declaration
public override bool IsLiveChild(ICinemachineCamera vcam, bool dominantChildOnly = false)
Parameters
Type Name Description
ICinemachineCamera vcam
bool dominantChildOnly

If true, will only return true if this vcam is the dominant live child
Returns
Type Description
bool

True if the vcam is currently actively influencing the state of this vcam
Overrides

OnTransitionFromCamera(ICinemachineCamera, Vector3, float)

Notification that this virtual camera is going live.

Declaration
public override void OnTransitionFromCamera(ICinemachineCamera fromCam, Vector3 worldUp, float deltaTime)
Parameters
Type Name Description
ICinemachineCamera fromCam

The camera being deactivated. May be null.
Vector3 worldUp

Default world Up, set by the CinemachineBrain
float deltaTime

Delta time for time-based effects (ignore if less than or equal to 0)
Overrides

Reset()

Reset the component to default values.

Declaration
protected override void Reset()
Overrides

SetWeight(int, float)

Set the weight of the child at an index.

Declaration
public void SetWeight(int index, float w)
Parameters
Type Name Description
int index

The child index. Only immediate CinemachineVirtualCameraBase children are counted.
float w

The weight to set. Can be any non-negative number.

SetWeight(CinemachineVirtualCameraBase, float)

Set the weight of the child CinemachineVirtualCameraBase.

Declaration
public void SetWeight(CinemachineVirtualCameraBase vcam, float w)
Parameters
Type Name Description
CinemachineVirtualCameraBase vcam

The child camera.
float w

The weight to set. Can be any non-negative number.

UpdateCameraCache()

Rebuild the camera cache if it's been invalidated

Declaration
protected override bool UpdateCameraCache()
Returns
Type Description
bool

True if a cache rebuild was performed, false if cache is up to date.
Overrides
