sizeThe width and height of the rectangle.

Inherited members

Variables

enabledEnabled Behaviours are Updated, disabled Behaviours are not.
attachedRigidbodyThe Rigidbody2D attached to the Collider2D's GameObject.
boundsThe world space bounding area of the collider.
isTriggerIs this collider configured as a trigger?
shapeCountThe number of separate shaped regions in the collider.
sharedMaterialThe PhysicsMaterial2D that is applied to this collider.
animationThe Animation attached to this GameObject (null if there is none attached).
audioThe AudioSource attached to this GameObject (null if there is none attached).

tagThe tag of this game object.
transformThe Transform attached to this GameObject (null if there is none attached).
hideFlagsShould the object be hidden, saved with the scene or modifiable by the user?
nameThe name of the object.

Functions

OverlapPointCheck if a collider overlaps a point in space.
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.
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.
GetInstanceIDReturns the instance id of the object.
ToStringReturns the name of the game object.

Static Functions

DestroyRemoves a gameobject, component or asset.
DestroyImmediateDestroys the object obj immediately. You are strongly recommended to use Destroy instead.
DontDestroyOnLoadMakes the object target not be destroyed automatically 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 if two objects refer to the same.

Messages

OnCollisionEnter2DSent when an incoming collider makes contact with this object's collider (2D physics only).
OnCollisionExit2DSent when a collider on another object stops touching this object's collider (2D physics only).
OnCollisionStay2DSent each frame where a collider on another object is touching this object's collider (2D physics only).
OnTriggerEnter2DSent when another object enters a trigger collider attached to this object (2D physics only).
OnTriggerExit2DSent when another object leaves a trigger collider attached to this object (2D physics only).
OnTriggerStay2DSent each frame where another object is within a trigger collider attached to this object (2D physics only).
