Description

Applies forces to simulate buoyancy, fluid-flow and fluid drag.

When any Collider2D overlap the area defined by the effector, calculations are made to determine if they are below the surfaceLevel. If they are not, no forces are applied. If they are then the effector will apply buoyancy forces in an attempt to move the Collider2D to the surfaceLevel i.e. they will float.

This effector is designed primarily to work with Collider2D that are set as triggers so that Collider2D can overlap the defined area and have buoyancy forces applied to them.

Properties

angularDragA force applied to slow angular movement of any Collider2D in contact with the effector.
densityThe density of the fluid used to calculate the buoyancy forces.
flowAngleThe angle of the force used to similate fluid flow.
flowMagnitudeThe magnitude of the force used to similate fluid flow.
flowVariationThe random variation of the force used to similate fluid flow.
linearDragA force applied to slow linear movement of any Collider2D in contact with the effector.
surfaceLevelDefines an arbitrary horizontal line that represents the fluid surface level.

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.
colliderMaskThe mask used to select specific layers allowed to interact with the effector.
useColliderMaskShould the collider-mask be used or the global collision matrix?

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 GameObject has one attached, null if it doesn't. Will also return disabled components.
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.
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.
FindObjectsOfTypeGets a list of all 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.
