Description 描述

Sent when an incoming collider makes contact with this object's collider (2D physics only).

当进入的碰撞器与这个对象的碰撞器接触，发送信息（仅限2D物理）。

Further information about the collision is reported in the Collision2D parameter passed during the call. If you don't need this information then you can declare OnCollisionEnter2D without the parameter.

关于碰撞的更多信息在调用期间中通过Collision2D参数报告。如果你不需要该信息，那么你可以声明OnCollisionEnter2D不带参数。

JavaScript:

function OnCollisionEnter2D(coll: Collision2D) {
	if (coll.gameObject.tag == "Enemy")
		coll.gameObject.SendMessage("ApplyDamage", 10);
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void OnCollisionEnter2D(Collision2D coll) {
        if (coll.gameObject.tag == "Enemy")
            coll.gameObject.SendMessage("ApplyDamage", 10);
 
    }
}
