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.
| edgeRadius | Controls the radius of all edges created by the Collider. |
| generationType | Specifies when to generate the Composite Collider geometry. |
| geometryType | Specifies the type of geometry the Composite Collider should generate. |
| offsetDistance | Vertices are offset by this distance when compositing multiple physic shapes. Any vertices between shapes within this distance are combined. |
| pathCount | The number of paths in the Collider. |
| pointCount | Gets the total number of points in all the paths within the Collider. |
| useDelaunayMesh | When 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. |
| vertexDistance | Controls the minimum distance allowed between generated vertices. |
| GenerateGeometry | Regenerates the Composite Collider geometry. |
| GetPath | Gets a path from the Collider by its index. |
| GetPathPointCount | Gets the number of points in the specified path from the Collider by its index. |
| enabled | Enabled Behaviours are Updated, disabled Behaviours are not. |
| isActiveAndEnabled | Reports whether a GameObject and its associated Behaviour is active and enabled. |
| attachedRigidbody | The Rigidbody2D attached to the Collider2D. |
| bounciness | Get the bounciness used by the collider. |
| bounds | The world space bounding area of the collider. |
| composite | Get the CompositeCollider2D that is available to be attached to the collider. |
| density | The density of the collider used to calculate its mass (when auto mass is enabled). |
| errorState | The error state that indicates the state of the physics shapes the 2D Collider tried to create. (Read Only) |
| friction | Get the friction used by the collider. |
| isTrigger | Is this collider configured as a trigger? |
| offset | The local offset of the collider geometry. |
| shapeCount | The number of active PhysicsShape2D the Collider2D is currently using. |
| sharedMaterial | The PhysicsMaterial2D that is applied to this collider. |
| usedByComposite | Sets whether the Collider will be used or not used by a CompositeCollider2D. |
| usedByEffector | Whether the collider is used by an attached effector or not. |
| gameObject | The game object this component is attached to. A component is always attached to a game object. |
| tag | The tag of this game object. |
| transform | The Transform attached to this GameObject. |
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |
| Cast | Casts the Collider shape into the Scene starting at the Collider position ignoring the Collider itself. |
| ClosestPoint | Returns a point on the perimeter of this Collider that is closest to the specified position. |
| CreateMesh | Creates a planar Mesh that is identical to the area defined by the Collider2D geometry. |
| Distance | Calculates the minimum separation of this collider against another collider. |
| GetContacts | Retrieves all contact points for this Collider. |
| GetShapeHash | Generates a simple hash value based upon the geometry of the Collider2D. |
| GetShapes | Gets all the PhysicsShape2D used by the Collider2D. |
| IsTouching | Check whether this collider is touching the collider or not. |
| IsTouchingLayers | Checks whether this collider is touching any colliders on the specified layerMask or not. |
| OverlapCollider | Get a list of all colliders that overlap this collider. |
| OverlapPoint | Check if a collider overlaps a point in space. |
| Raycast | Casts a ray into the Scene that starts at the Collider position and ignores the Collider itself. |
| BroadcastMessage | Calls the method named methodName on every MonoBehaviour in this game object or any of its children. |
| CompareTag | Checks the GameObject's tag against the defined tag. |
| GetComponent | Returns the component of type if the GameObject has one attached. |
| GetComponentInChildren | Returns the Component of type in the GameObject or any of its children using depth first search. |
| GetComponentInParent | Returns the Component of type in the GameObject or any of its parents. |
| GetComponents | Returns all components of Type type in the GameObject. |
| GetComponentsInChildren | Returns all components of Type type in the GameObject or any of its children. Works recursively. |
| GetComponentsInParent | Returns all components of Type type in the GameObject or any of its parents. |
| SendMessage | Calls the method named methodName on every MonoBehaviour in this game object. |
| SendMessageUpwards | Calls the method named methodName on every MonoBehaviour in this game object and on every ancestor of the behaviour. |
| TryGetComponent | Gets the component of the specified type, if it exists. |
| GetInstanceID | Gets the instance ID of the object. |
| ToString | Returns the name of the object. |
| Destroy | Removes a GameObject, component or asset. |
| DestroyImmediate | Destroys the object obj immediately. You are strongly recommended to use Destroy instead. |
| DontDestroyOnLoad | Do not destroy the target Object when loading a new Scene. |
| FindObjectOfType | Returns the first active loaded object of Type type. |
| FindObjectsOfType | Gets a list of all loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| bool | Does 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. |
| OnCollisionEnter2D | Sent when an incoming collider makes contact with this object's collider (2D physics only). |
| OnCollisionExit2D | Sent when a collider on another object stops touching this object's collider (2D physics only). |
| OnCollisionStay2D | Sent each frame where a collider on another object is touching this object's collider (2D physics only). |
| OnTriggerEnter2D | Sent when another object enters a trigger collider attached to this object (2D physics only). |
| OnTriggerExit2D | Sent when another object leaves a trigger collider attached to this object (2D physics only). |
| OnTriggerStay2D | Sent each frame where another object is within a trigger collider attached to this object (2D physics only). |
