Description

Collider for 2D physics representing shapes defined by the corresponding Tilemap.

Properties

extrusionFactorThe amount of Collider shapes each Tile extrudes to facilitate compositing with neighboring Tiles. This eliminates fine gaps between Tiles when using a CompositeCollider2D. This is calculated in Unity units within world space.
hasTilemapChangesReturns true if there are Tilemap changes that require processing for Collider updates. Returns false otherwise.
maximumTileChangeCountMaximum number of Tile Changes accumulated before doing a full collider rebuild instead of an incremental rebuild.

Public Methods

ProcessTilemapChangesProcesses Tilemap changes for Collider updates immediately, if there are any.

Public Methods

CastCasts the Collider shape into the Scene starting at the Collider position ignoring the Collider itself.
ClosestPointReturns a point on the perimeter of this Collider that is closest to the specified position.
CreateMeshCreates a planar Mesh that is identical to the area defined by the Collider2D geometry.
DistanceCalculates the minimum separation of this collider against another collider.
GetContactsRetrieves all contact points for this Collider.
GetShapeHashGenerates a simple hash value based upon the geometry of the Collider2D.
GetShapesGets all the PhysicsShape2D used by the Collider2D.
IsTouchingCheck whether this collider is touching the collider or not.
IsTouchingLayersChecks whether this collider is touching any colliders on the specified layerMask or not.
OverlapColliderGet a list of all colliders that overlap this collider.
OverlapPointCheck if a collider overlaps a point in space.
RaycastCasts a ray into the Scene that starts at the Collider position and ignores the Collider itself.
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.
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.

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.

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).
