Description

Constrains the orientation of an object relative to the position of one or more source objects, such that the object is facing the average position of the sources. The LookAtConstraint is a simplified AimConstraint typically used with a Camera.

Properties

constraintActiveActivates or deactivates the constraint.
lockedLocks the offset and rotation at rest.
rollThe rotation angle along the z axis of the object. The constraint uses this property to calculate the world up vector when Animations.LookAtConstraint.UseUpObject is false.
rotationAtRestThe rotation used when the sources have a total weight of 0.
rotationOffsetRepresents an offset from the constrained orientation.
sourceCountThe number of sources set on the component (Read Only).
useUpObjectDetermines how the up vector is calculated.
weightThe weight of the constraint component.
worldUpObjectThe world up object, used to calculate the world up vector when Animations.LookAtConstraint.UseUpObject is true.

Public Methods

AddSourceAdds a constraint source.
GetSourceGets a constraint source by index.
GetSourcesGets the list of sources.
RemoveSourceRemoves a source from the component.
SetSourceSets a source at a specified index.
SetSourcesSets the list of sources on the component.

Public Methods

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagChecks the GameObject's tag against the defined tag.
GetComponentGets a reference to a component of type T on the same GameObject as the component specified.
GetComponentInChildrenGets a reference to a component of type T on the same GameObject as the component specified, or any child of the GameObject.
GetComponentInParentGets a reference to a component of type T on the same GameObject as the component specified, or any parent of the GameObject.
GetComponentsGets references to all components of type T on the same GameObject as the component specified.
GetComponentsInChildrenGets references to all components of type T on the same GameObject as the component specified, and any child of the GameObject.
GetComponentsInParentGets references to all components of type T on the same GameObject as the component specified, and any parent of the GameObject.
SendMessageCalls the method named methodName on every MonoBehaviour in this game object.
SendMessageUpwardsCalls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour.
TryGetComponentGets the component of the specified type, if it exists.
GetInstanceIDGets the instance ID of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.

Operators

boolDoes the object exist?
operator !=Compares if two objects refer to a different object.
operator ==Compares two object references to see if they refer to the same object.
