The Circle Collider 2D is a collider that interacts with the 2D physics system for approximate collision detection. The Circle Collider 2D, as the name suggests, is in circular shape with a defined position and radius within the local coordinate space of a Sprite.
属性 | 功能 | |
---|---|---|
Material | Select the Physics Material 2D that determines properties of collisions, such as friction and bounce. | |
Is Trigger | Enable this option if you want the Collider 2D to behave as a trigger. The physics system ignores the Collider 2D when you enable this option. | |
Used by Effector | Enable this option if you want an attached Effector 2D to use this Collider 2D. | |
Offset | Set the local offset values of the Collider 2D geometry. | |
Radius | Set the radius of the Circle Collider 2D in local space units. | |
Layer Overrides | Expand this option to use the Layer override settings. | |
Layer Override Priority | Assign the decision priority that this Collider 2D uses when resolving conflicting decisions on whether a contact between itself and another Collider 2D should happen or not. For more information, refer to its API page. | |
Include Layers | Select the additional Layers for this Collider 2D to 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 for this Collider 2D to exclude when deciding if a contact with another Collider 2D 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. | |
Contact Capture Layers | Select the Layers of other Collider 2D involved in contact with this Collider2D that you want to capture. 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. |
