Custom Collider 2D
The Custom Collider 2D is a Collider that interacts with the 2D physics system. Unlike other Colliders, you do not configure the Collider in-Editor, instead you configure the Collider by assigning PhysicsShape2D geometry to it via the PhysicsShapeGroup2D API. You can further define the Collider by adding, removing and modifying the PhysicsShape2D shapes. Refer to the PhysicsShape2D API documentation for more information. This also means that a Custom Collider 2D can contain an unlimited number of low-level PhysicsShape2D and represent any type of shape, or emulate other types of Collider 2D.
| プロパティ | 機能 | |
|---|---|---|
| Material | Select the Physics Material 2D that determines properties of collisions, such as friction and bounce. | |
| Is Trigger | Enable this if you want this Collider 2D to behave as a trigger. The physics system ignores this Collider when this is enabled. | |
| Used by Effector | Enable this if you want the Collider 2D to be used by an attached Effector 2D. | |
| Offset | Set the local offset values of the Collider 2D geometry. | |
| Custom Shape Count (Read only) | Indicates how many PhysicsShape2D the Collider is using. |
|
| Custom Vertex Count (Read Only) | Indicates how many vertices all PhysicsShape2D in the Collider are using. |
|
| Layer Overrides | Expand for the Layer override settings. | |
| Layer Override Priority | Assign the decision priority that this Collider2D uses when resolving conflicting decisions on whether a contact between itself and another Collision2D should happen or not. Refer to its API page for more information. | |
| Include Layers | Select the additional Layers that this Collider 2D should include when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information. | |
| Exclude Layers | Select the additional Layers that this Collider 2D should exclude when deciding if a contact with another Collider2D should happen or not. Refer to its API documentation for more information. | |
| Force Send Layers | Select the Layers that this Collider 2D is allowed to send forces to during a Collision contact with another Collider2D. Refer to its API documentation for more information. | |
| Force Receive Layers | Select the Layers that this Collider 2D can receive forces from during a Collision contact with another Collider2D. Refer to its API documentation for more information. | |
| Contract Capture Layers | Select the Layers of other Collider 2D, involved in contacts with this Collider2D, that will be captured. Refer to its API documentation for more information. | |
| Callback Layers | Select the Layers that this Collider 2D, during a contact with another Collider2D, will report collision or trigger callbacks for. Refer to its API documentation for more information. | |
Using the Custom Collider 2D
When assigning PhysicsShape2D to the Custom Collider 2D, you can do so either during Edit mode or Play mode. When modifying the Custom Collider 2D in Edit mode, Unity saves all assigned PhysicsShape2D and associated vertices in the Unity Scene, and the CustomCollider2D retains its configuration when the Scene is loaded. This makes it possible to use Edit mode authoring scripts to create custom geometry.
When modifying the Custom Collider 2D during Play mode, the Collider will not retain any changes made to assigned PhysicsShape2D and their associated vertices, and all changes will be lost when exiting Play mode.
