Class CinemachineClearShot

Cinemachine ClearShot is a "manager camera" that owns and manages a set of Virtual Camera gameObject children. When Live, the ClearShot will check the children, and choose the one with the best quality shot and make it Live.

This can be a very powerful tool. If the child cameras have CinemachineCollider extensions, they will analyze the scene for target obstructions, optimal target distance, and other items, and report their assessment of shot quality back to the ClearShot parent, who will then choose the best one. You can use this to set up complex multi-camera coverage of a scene, and be assured that a clear shot of the target will always be available.

If multiple child cameras have the same shot quality, the one with the highest priority will be chosen.

You can also define custom blends between the ClearShot children.

Properties

ChildCameras

The list of child cameras. These are just the immediate children in the hierarchy.

Declaration
public CinemachineVirtualCameraBase[] ChildCameras { get; }
Property Value
Type Description
CinemachineVirtualCameraBase[]

Description

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

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

Follow

Get the current Follow target. Returns parent's Follow if parent is non-null and no specific Follow defined for this camera

Declaration
public override Transform Follow { get; set; }
Property Value
Type Description
Transform
Overrides

IsBlending

Is there a blend in progress?

Declaration
public bool IsBlending { get; }
Property Value
Type Description
Boolean

LiveChild

Get the current "best" child virtual camera, that would be chosen if the ClearShot camera were active.

Declaration
public ICinemachineCamera LiveChild { get; set; }
Property Value
Type Description
ICinemachineCamera

LookAt

Get the current LookAt target. Returns parent's LookAt if parent is non-null and no specific LookAt defined for this camera

Declaration
public override Transform LookAt { get; set; }

Type Description
Transform
Overrides

State

The CameraState of the currently live child

Declaration
public override CameraState State { get; }

Overrides

Methods

ForceCameraPosition(Vector3, Quaternion)

Force the virtual camera to assume a given position and orientation

Declaration
public override void ForceCameraPosition(Vector3 pos, Quaternion rot)
Parameters
Type Name Description
Vector3 pos

Worldspace pposition to take
Quaternion rot

Worldspace orientation to take
Overrides

InternalUpdateCameraState(Vector3, Single)

Internal use only. 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
Single deltaTime

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

IsLiveChild(ICinemachineCamera, Boolean)

Check whether the vcam a live child of this camera.

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

The Virtual Camera to check
Boolean dominantChildOnly

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

Overrides

OnDisable()

Uninstall the GUI handler

Declaration

Overrides

OnEnable()

Makes sure the internal child cache is up to date

Declaration
protected override void OnEnable()
Overrides

OnTargetObjectWarped(Transform, Vector3)

This is called to notify the vcam that a target got warped, so that the vcam can update its internal state to make the camera also warp seamlessy.
