Description

A Collider that can merge other Colliders together.

A CompositeCollider2D merges other Colliders together when their Collider2D.usedByComposite is set to true.

When a Collider is used by a Composite Collider, the Editor will ignore and not show the Collider2D.sharedMaterial, Collider2D.isTrigger & Collider2D.usedByComposite properties. The same properties on the CompositeCollider2D will be used instead. You should set these properties on the Composite Collider instead to merge all Colliders into the Composite Collider.

Composite Colliders can only merge BoxCollider2D and PolygonCollider2D.

Properties

edgeRadiusControls the radius of all edges created by the Collider.
generationTypeSpecifies when to generate the Composite Collider geometry.
geometryTypeSpecifies the type of geometry the Composite Collider should generate.
offsetDistanceVertices are offset by this distance when compositing multiple physic shapes. Any vertices between shapes within this distance are combined.
pathCountThe number of paths in the Collider.
pointCountGets the total number of points in all the paths within the Collider.
useDelaunayMeshWhen the value is true, the Collider uses an additional Delaunay triangulation step to produce the Collider mesh. When the value is false, this additional step does not occur.
vertexDistanceControls the minimum distance allowed between generated vertices.

Public Methods

GenerateGeometryRegenerates the Composite Collider geometry.
GetPathGets a path from the Collider by its index.
GetPathPointCountGets the number of points in the specified path from the Collider by its index.

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.
GetComponentReturns the component of type if the GameObject has one attached.
GetComponentInChildrenReturns the Component of type in the GameObject or any of its children using depth first search.
GetComponentInParentReturns the Component of 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. 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.
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.
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.

Messages

OnCollisionEnter2DSent when an incoming collider makes contact with 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).
