当游戏对象与主角碰撞时，如何破坏整个预制件？

Question

What I'm trying to do is to make my monster disappear when my main char collides with it. So, I attached this script to my monster, but I can't get it to work. I succeeded in destroying monster's RigidBody component but I can't seem to destroy the whole thing.

using UnityEngine;
using System.Collections;

public class Dying: MonoBehaviour {
private Rigidbody rbody;
public GameObject prefab;


void Start () {
    rbody = GetComponent<Rigidbody>();
GameObject obj = Instantiate(prefab);

}


void Update () {


} 
void OnCollisionEnter(Collision col)
{ 
    print(col.collider.name);
    if(col.collider.name =="unitychan")
    {
         Destroy(prefab.gameObject);

    }
 }
}

Answer 1

What might be the problem is that you are trying to destroy either the object running the script, or some other random object. You typically never destroy the object running the script. Also, col contains the object that was collided with. so you can just do this:

void OnCollisionEnter(Collision col)
{
    if (!col.collider.name == "unitychan") return;

    Destroy(col.gameObject);
}
