Class CinemachineOrbitalTransposer

This is a CinemachineComponent in the the Body section of the component pipeline. Its job is to position the camera in a variable relationship to a the vcam's Follow target object, with offsets and damping.

This component is typically used to implement a camera that follows its target. It can accept player input from an input device, which allows the player to dynamically control the relationship between the camera and the target, for example with a joystick.

The OrbitalTransposer introduces the concept of Heading, which is the direction in which the target is moving, and the OrbitalTransposer will attempt to position the camera in relationship to the heading, which is by default directly behind the target. You can control the default relationship by adjusting the Heading Bias setting.

If you attach an input controller to the OrbitalTransposer, then the player can also control the way the camera positions itself in relation to the target heading. This allows the camera to move to any spot on an orbit around the target.

Fields

m_Heading

The definition of Forward. Camera will follow behind.

Declaration
public CinemachineOrbitalTransposer.Heading m_Heading
Field Value
Type Description
CinemachineOrbitalTransposer.Heading

m_HeadingIsSlave

Drive the x-axis setting programmatically. Automatic heading updating will be disabled.

Declaration
public bool m_HeadingIsSlave
Field Value
Type Description
Boolean

m_RecenterToTargetHeading

Parameters that control Automating Heading Recentering

Declaration
public AxisState.Recentering m_RecenterToTargetHeading
Field Value
Type Description
AxisState.Recentering

m_XAxis

Axis representing the current heading. Value is in degrees and represents a rotation about the up vector

Declaration

Field Value
Type Description
AxisState

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

GetAxisClosestValue(Vector3, Vector3)

What axis value would we need to get as close as possible to the desired cameraPos?

Declaration
public float GetAxisClosestValue(Vector3 cameraPos, Vector3 up)
Parameters
Type Name Description
Vector3 cameraPos

camera position we would like to approximate
Vector3 up

world up
Returns
Type Description
Single

The best value to put into the X axis, to approximate the desired camera pos

GetTargetCameraPosition(Vector3)

Internal API for the Inspector Editor, so it can draw a marker at the target

Declaration
public override Vector3 GetTargetCameraPosition(Vector3 worldUp)
Parameters
Type Name Description
Vector3 worldUp

Current effective world up
Returns
Type Description
Vector3

The position of the Follow target
Overrides

MutateCameraState(ref CameraState, Single)

Positions the virtual camera according to the transposer rules.

Declaration
public override void MutateCameraState(ref CameraState curState, float deltaTime)
Parameters
Type Name Description
CameraState curState

The current camera state
Single deltaTime

Used for damping. If less than 0, no damping is done.
Overrides

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
Overrides

OnTransitionFromCamera(ICinemachineCamera, Vector3, Single, ref CinemachineVirtualCameraBase.TransitionParams)

Notification that this virtual camera is going live. Base class implementation does nothing.

Declaration
public override bool OnTransitionFromCamera(ICinemachineCamera fromCam, Vector3 worldUp, float deltaTime, ref CinemachineVirtualCameraBase.TransitionParams transitionParams)
Parameters
Type Name Description
ICinemachineCamera fromCam

The camera being deactivated. May be null.
Vector3 worldUp

Default world Up, set by the CinemachineBrain
Single deltaTime

Delta time for time-based effects (ignore if less than or equal to 0)
CinemachineVirtualCameraBase.TransitionParams transitionParams

Transition settings for this vcam
Returns
Type Description
Boolean

True if the vcam should do an internal update as a result of this call
Overrides

OnValidate()

Legacy support for old serialized versions

Declaration
protected override void OnValidate()
Overrides

UpdateHeading(Single, Vector3, ref AxisState)

Update the X axis and calculate the heading. This can be called by a delegate with a custom axis. Note that this method is obsolete.

Declaration
public float UpdateHeading(float deltaTime, Vector3 up, ref AxisState axis)
Parameters
Type Name Description
Single deltaTime

Used for damping. If less than 0, no damping is done.
Vector3 up

World Up, set by the CinemachineBrain
AxisState axis
Returns
Type Description
Single

Axis value

UpdateHeading(Single, Vector3, ref AxisState, ref AxisState.Recentering, Boolean)

Update the X axis and calculate the heading. This can be called by a delegate with a custom axis.

Declaration
public float UpdateHeading(float deltaTime, Vector3 up, ref AxisState axis, ref AxisState.Recentering recentering, bool isLive)
Parameters
Type Name Description
Single deltaTime

Used for damping. If less than 0, no damping is done.
Vector3 up

World Up, set by the CinemachineBrain
