Description

Applies tangent forces along the surfaces of colliders.

When the source Collider2D is a trigger, the effector will apply forces whenever the target Collider2D overlaps the source. When the source Collider isn't a trigger, the effector will apply forces whenever the target Collider2D is in contact with the source only.

This effector can be used to create constant speed elevators and moving surfaces.

Properties

forceScaleThe scale of the impulse force applied while attempting to reach the surface speed.
speedThe speed to be maintained along the surface.
speedVariationThe speed variation (from zero to the variation) added to base speed to be applied.
useBounceShould bounce be used for any contact with the surface?
useContactForceShould the impulse force but applied to the contact point?
useFrictionShould friction be used for any contact with the surface?

Properties

enabledEnabled Behaviours are Updated, disabled Behaviours are not.
isActiveAndEnabledReports whether a GameObject and its associated Behaviour is active and enabled.
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.
colliderMaskThe mask used to select specific layers allowed to interact with the effector.
useColliderMaskShould the collider-mask be used or the global collision matrix?
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.
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.
GetComponentIndexGets the index of the component on its parent 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.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadDo not destroy the target Object when loading a new Scene.
FindAnyObjectByTypeRetrieves any active loaded object of Type type.
FindFirstObjectByTypeRetrieves the first active loaded object of Type type.
FindObjectOfTypeReturns the first active loaded object of Type type.
FindObjectsByTypeRetrieves a list of all loaded objects of Type type.
FindObjectsOfTypeGets a list of all loaded objects of Type type.
InstantiateClones the object original and returns the clone.
InstantiateAsyncCaptures a snapshot of the original object (that must be related to some GameObject) and returns the AsyncInstantiateOperation.

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.
