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.

Fields

m_BiasX

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

Declaration
[Range(-0.5F, 0.5F)]
[Tooltip("A non-zero bias will move the target position horizontally away from the center of the soft zone.")]
public float m_BiasX
Field Value
Type Description
Single

m_BiasY

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

Declaration
[Range(-0.5F, 0.5F)]
[Tooltip("A non-zero bias will move the target position vertically away from the center of the soft zone.")]
public float m_BiasY
Field Value
Type Description
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
[Tooltip("Force target to center of screen when this camera activates.  If false, will clamp target to the edges of the dead zone")]
public bool m_CenterOnActivate
Field Value
Type Description
Boolean

m_DeadZoneHeight

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

Declaration
[Range(0F, 2F)]
[Tooltip("Camera will not rotate vertically if the target is within this range of the position.")]
public float m_DeadZoneHeight
Field Value
Type Description
Single

m_DeadZoneWidth

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

Declaration
[Range(0F, 2F)]
[Tooltip("Camera will not rotate horizontally if the target is within this range of the position.")]
public float m_DeadZoneWidth
Field Value
Type Description
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
[Space]
[Range(0F, 20F)]

public float m_HorizontalDamping
Field Value
Type Description
Single

m_LookaheadIgnoreY

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

Declaration
[Tooltip("If checked, movement along the Y axis will be ignored for lookahead calculations")]
public bool m_LookaheadIgnoreY
Field Value
Type Description
Boolean

m_LookaheadSmoothing

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

Declaration
[Tooltip("Controls the smoothness of the lookahead algorithm.  Larger values smooth out jittery predictions and also increase prediction lag")]
[Range(3F, 30F)]
public float m_LookaheadSmoothing
Field Value
Type Description
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

Declaration
[Range(-0.5F, 1.5F)]
[Tooltip("Vertical screen position for target, The camera will rotate to position the tracked object here.")]
public float m_ScreenY
Field Value
Type Description
Single

m_SoftZoneHeight

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
