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.

Properties

enabledEnabled Behaviours are Updated, disabled Behaviours are not.
isActiveAndEnabledHas the Behaviour had active and enabled called?
gameObjectThe game object this component is attached to. A component is always attached to a game object.
tagThe tag of this game object.
transformThe Transform attached to this GameObject.
hideFlagsShould the object be hidden, saved with the Scene or modifiable by the user?
nameThe name of the object.

Public Methods

BroadcastMessageCalls the method named methodName on every MonoBehaviour in this game object or any of its children.
CompareTagIs this game object tagged with tag ?
GetComponentReturns the component of Type type if the game object has one attached, null if it doesn't.
GetComponentInChildrenReturns the component of Type type in the GameObject or any of its children using depth first search.
GetComponentInParentReturns the component of Type type in the GameObject or any of its parents.
GetComponentsReturns all components of Type type in the GameObject.
GetComponentsInChildrenReturns all components of Type type in the GameObject or any of its children using depth first search. Works recursively.
GetComponentsInParentReturns all components of Type type in the GameObject or any of its parents.
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.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the object.

Static Methods

DestroyRemoves a GameObject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsOfTypeReturns a list of all active loaded objects of Type type.
InstantiateClones the object original and returns the clone.

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.
