Class CinemachineComposer

This is a CinemachineComponent in the Aim section of the component pipeline. Its job is to aim the camera at the vcam's LookAt target object, with configurable offsets, damping, and composition rules.

The composer does not change the camera's position. It will only pan and tilt the camera where it is, in order to get the desired framing. To move the camera, you have to use the virtual camera's Body section.

public class CinemachineComposer : CinemachineComponentBase

Fields

m_BiasX

A non-zero bias will move the targt position away from the center of the soft zone

Declaration

public float m_BiasX

Field Value

Type	Description
System.Single

m_BiasY

A non-zero bias will move the targt position away from the center of the soft zone

Declaration

public float m_BiasY

Field Value

Type	Description
System.Single

m_CenterOnActivate

Force target to center of screen when this camera activates. If false, will clamp target to the edges of the dead zone

Declaration

public bool m_CenterOnActivate

Field Value

Type	Description
System.Boolean

m_DeadZoneHeight

Camera will not rotate vertically if the target is within this range of the position

Declaration

public float m_DeadZoneHeight

Field Value

Type	Description
System.Single

m_DeadZoneWidth

Camera will not rotate horizontally if the target is within this range of the position

Declaration

public float m_DeadZoneWidth

Field Value

Type	Description
System.Single

m_HorizontalDamping

How aggressively the camera tries to follow the target in the screen-horizontal direction. Small numbers are more responsive, rapidly orienting the camera to keep the target in the dead zone. Larger numbers give a more heavy slowly responding camera. Using different vertical and horizontal settings can yield a wide range of camera behaviors.

Declaration

public float m_HorizontalDamping

Field Value

Type	Description
System.Single

m_LookaheadIgnoreY

If checked, movement along the Y axis will be ignored for lookahead calculations

Declaration

public bool m_LookaheadIgnoreY

Field Value

Type	Description
System.Boolean

m_LookaheadSmoothing

Controls the smoothness of the lookahead algorithm. Larger values smooth out jittery predictions and also increase prediction lag

Declaration

public float m_LookaheadSmoothing

Field Value

Type	Description
System.Single

m_LookaheadTime

This setting will instruct the composer to adjust its target offset based on the motion of the target. The composer will look at a point where it estimates the target will be this many seconds into the future. Note that this setting is sensitive to noisy animation, and can amplify the noise, resulting in undesirable camera jitter. If the camera jitters unacceptably when the target is in motion, turn down this setting, or animate the target more smoothly.

Declaration

public float m_LookaheadTime

Field Value

Type	Description
System.Single

m_ScreenX

Horizontal screen position for target. The camera will rotate to the position the tracked object here

Declaration

public float m_ScreenX

Field Value

Type	Description
System.Single

m_ScreenY

Vertical screen position for target, The camera will rotate to to position the tracked object here

Declaration

public float m_ScreenY

Field Value

Type	Description
System.Single

m_SoftZoneHeight

When target is within this region, camera will gradually move to re-align towards the desired position, depending onm the damping speed

Declaration

public float m_SoftZoneHeight

Field Value

Type	Description
System.Single

m_SoftZoneWidth

When target is within this region, camera will gradually move to re-align towards the desired position, depending onm the damping speed

Declaration

public float m_SoftZoneWidth

Field Value

Type	Description
System.Single

m_TrackedObjectOffset

Target offset from the object's center in LOCAL space which the Composer tracks. Use this to fine-tune the tracking target position when the desired area is not in the tracked object's center

Declaration

public Vector3 m_TrackedObjectOffset

Field Value

Type	Description
Vector3

m_VerticalDamping

How aggressively the camera tries to follow the target in the screen-vertical direction. Small numbers are more responsive, rapidly orienting the camera to keep the target in the dead zone. Larger numbers give a more heavy slowly responding camera. Using different vertical and horizontal settings can yield a wide range of camera behaviors.

Declaration

public float m_VerticalDamping

Field Value

Type	Description
System.Single

Properties

IsValid

True if component is enabled and has a LookAt defined

Declaration

public override bool IsValid { get; }

Property Value

Type	Description
System.Boolean

Overrides

CinemachineComponentBase.IsValid

Stage

Get the Cinemachine Pipeline stage that this component implements. Always returns the Aim stage

Declaration

public override CinemachineCore.Stage Stage { get; }

Property Value

Type	Description
CinemachineCore.Stage

Overrides

CinemachineComponentBase.Stage

TrackedPoint

Internal API for inspector

Declaration

public Vector3 TrackedPoint { get; }

Property Value

Type	Description
Vector3

Methods

GetLookAtPointAndSetTrackedPoint(Vector3, Vector3, Single)

Apply the target offsets to the target location. Also set the TrackedPoint property, taking lookahead into account.

Declaration

protected virtual Vector3 GetLookAtPointAndSetTrackedPoint(Vector3 lookAt, Vector3 up, float deltaTime)

Parameters

Type	Name	Description
Vector3	lookAt	The unoffset LookAt point
Vector3	up
System.Single	deltaTime

Returns

Type	Description
Vector3	The LookAt point with the offset applied

MutateCameraState(ref CameraState, Single)

Applies the composer rules and orients the camera accordingly

Declaration

public override void MutateCameraState(ref CameraState curState, float deltaTime)

Parameters

Type	Name	Description
CameraState	curState	The current camera state
System.Single	deltaTime	Used for calculating damping. If less than zero, then target will snap to the center of the dead zone.

Overrides

CinemachineComponentBase.MutateCameraState(ref CameraState, Single)

OnTargetObjectWarped(Transform, Vector3)

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

Declaration

public override void OnTargetObjectWarped(Transform target, Vector3 positionDelta)

Parameters

Type	Name	Description
Transform	target	The object that was warped
Vector3	positionDelta	The amount the target's position changed
