Implemented in:UnityEngine.Physics2DModule
Asset type that defines the surface properties of a Collider2D.
When two Colllider2D come into contact, the physics system uses both friction and bounciness if it needs to calculate a collision response.
| Property | Description |
|---|---|
| bounceCombine | Determines how the effective bounciness is calculated when two Collider2D come into contact. |
| bounciness | Coefficient of restitution. |
| friction | Coefficient of friction. |
| frictionCombine | Determines how the effective friction is calculated when two Collider2D come into contact. |
| Method | Description |
|---|---|
| GetCombinedValues | Calculates the effective value used when two Collider2D come into contact with their own PhysicsMaterial2D. |
| Property | Description |
|---|---|
| hideFlags | Should the object be hidden, saved with the Scene or modifiable by the user? |
| name | The name of the object. |
| Method | Description |
|---|---|
| GetInstanceID | Gets the instance ID of the object. |
| ToString | Returns the name of the object. |
| Method | Description |
|---|---|
| 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. |
| FindAnyObjectByType | Retrieves any active loaded object of Type type. |
| FindFirstObjectByType | Retrieves the first active loaded object of Type type. |
| FindObjectsByType | Retrieves a list of all loaded objects of Type type. |
| Instantiate | Clones the object original and returns the clone. |
| InstantiateAsync | Captures a snapshot of the original object (that must be related to some GameObject) and returns the AsyncInstantiateOperation. |
| Operator | Description |
|---|---|
| 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. |
