public struct ContactPoint2D
Remarks
A contact point describes a point of intersection between two Collider2D. ContactPoint2D can only exist on Collider2D that are not set to be triggers as triggers do not define contact points.

Properties
Property | Description |
|---|---|
| bounciness | The effective bounciness used for the ContactPoint2D. |
| collider | The incoming Collider2D involved in the collision with the ContactPoint2D.otherCollider. |
| enabled | Indicates whether the collision response or reaction is enabled or disabled. |
| friction | The effective friction used for the ContactPoint2D. |
| normal | Surface normal at the contact point. |
| normalImpulse | Gets the impulse applied at the contact point along the ContactPoint2D.normal. |
| otherCollider | The other Collider2D involved in the collision with the ContactPoint2D.collider. |
| otherRigidbody | The other Rigidbody2D involved in the collision with the ContactPoint2D.rigidbody. |
| point | The point of contact between the two colliders in world space. |
| relativeVelocity | Gets the relative velocity of the two colliders at the contact point (Read Only). |
| rigidbody | The incoming Rigidbody2D involved in the collision with the ContactPoint2D.otherRigidbody. |
| separation | Gets the distance between the colliders at the contact point. |
| tangentImpulse | Gets the impulse applied at the contact point which is perpendicular to the ContactPoint2D.normal. |
