Collision.contacts

Description

Точки соприкосновения сгенерированные физическим движком.

Every contact contains a contact point, normal and the two colliders that collided (see ContactPoint). From inside OnCollisionStay or OnCollisionEnter you can always be sure that contacts has at least one element.

no example available in C#

// A grenade
// - instantiates a explosion prefab when hitting a surface
// - then destroys itself

public class ExampleClass : MonoBehaviour

    public Transform explosionPrefab;
    void OnCollisionEnter(Collision collision)
    {
        ContactPoint contact = collision.contacts[0];
        Quaternion rot = Quaternion.FromToRotation(Vector3.up, contact.normal);
        Vector3 pos = contact.point;
        Instantiate(explosionPrefab, pos, rot);
        Destroy(gameObject);
