MonoBehaviour.OnCollisionEnter(Collision)

Parámetros

Descripción

OnCollisionEnter se llama cuando el Collider o Rigidbody entra en contacto con otro Collider o Rigidbody.

In contrast to OnTriggerEnter, OnCollisionEnter is passed the Collision class and not a Collider. La clase Collision contiene información sobre puntos de contacto, velocidad de impacto, etc. Si no vas a usar el parámetro collisionInfo en la función, déjalo fuera para evitar cálculos innecesarios. Notes: Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached. Collision events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
	AudioSource audio;
	
	void Start() {
		audio = GetComponent<AudioSource>();
	}
	
    void OnCollisionEnter(Collision collision) {
        foreach (ContactPoint contact in collision.contacts) {
            Debug.DrawRay(contact.point, contact.normal, Color.white);
        }
        
        if (collision.relativeVelocity.magnitude > 2)
            audio.Play(); 
    }
}

OnCollisionEnter can be a co-routine, simply use the yield statement in the function.
