碰到球删除球

参照实例化预制体,把预制体球添加标签Player.
移动脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class move : MonoBehaviour {
    private Rigidbody ri;
    public float speed = 5.0f;
    // Use this for initialization
    void Start () {
        ri = this.GetComponent<Rigidbody>();
    }

    // Update is called once per frame
    void Update () 
    {
        if (Input.GetKey(KeyCode.W))
        {
            ri.MovePosition(transform.position + Vector3.forward * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.S))
        {
            ri.MovePosition(transform.position + Vector3.back * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.A))
        {
            ri.MovePosition(transform.position + Vector3.left * speed * Time.deltaTime);
        }
        if (Input.GetKey(KeyCode.D))
        {
            ri.MovePosition(transform.position + Vector3.right * speed * Time.deltaTime);
        }
    }
        void OnCollisionEnter(Collision coll)//被碰撞的形参
        {
            if (coll.gameObject.tag == "Player")//如果碰到标签为"Player"的物体,就销毁它
            {
                Destroy(coll.gameObject);
            }
        }
    }

实例化物体脚本

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class copysp : MonoBehaviour {
    public GameObject ga;
    // Use this for initialization
    void Start () {
        for (int i = 0; i < 10; i++)
        {
            Vector3 ve3 = new Vector3(Random.Range(-5.0f, 5.0f), 2.0f, Random.Range(-5.0f, 5.0f));
            Instantiate(ga, ve3, Quaternion.identity);
        }
    }

    // Update is called once per frame
    void Update () {

    }
}
