Unity实现我的世界摧毁方块功能

事情是这样的，今天我打算复原我的世界，做到摧毁方块的功能时，就想不到可以用什么办法来检测，一开始我想用射线检测，可射线检测我不会...于是我又想到了碰撞检测

Fire.cs，代码如下。

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


public class Fire : MonoBehaviour {
	GameObject obj;
	void Start() {
		//获取球类对象
		obj = GameObject.Find("FirePoint");
	}
	void Update() {
		if (Input.GetMouseButton(0)) {
			obj = GameObject.Find ("FirePoint(Clone)");
			if (obj) {
				obj = GameObject.Find ("FirePoint(Clone)");
				this.obj.transform.Translate(new Vector3(0, 0, 2 * Time.deltaTime));
				obj = GameObject.Find("FirePoint");
			} else {
				obj = GameObject.Find("FirePoint");
				GameObject clone = Instantiate(obj, obj.transform.position, obj.transform.rotation);
				obj = GameObject.Find ("FirePoint(Clone)");
				this.obj.transform.Translate(new Vector3(0, 0, 2 * Time.deltaTime));
				Destroy(clone, 1.25f);
				obj = GameObject.Find("FirePoint");
			}
			obj = GameObject.Find("FirePoint");
		}
		if (Input.GetMouseButton(1)) {
			obj = GameObject.Find ("FirePoint(Clone)");
			if (obj) {
				obj = GameObject.Find ("FirePoint(Clone)");
				this.obj.transform.Translate(new Vector3(0, 0, 2 * Time.deltaTime));
				obj = GameObject.Find("FirePoint");
			} else {
				obj = GameObject.Find("FirePoint");
				GameObject clone = Instantiate(obj, obj.transform.position, obj.transform.rotation);
				obj = GameObject.Find ("FirePoint(Clone)");
				this.obj.transform.Translate(new Vector3(0, 0, 2 * Time.deltaTime));
				Destroy(clone, 1.25f);
				obj = GameObject.Find("FirePoint");
			}
			obj = GameObject.Find("FirePoint");
		}
	}
}

把这个脚本附到摄像机身上。

下一个脚本是挂在要被挖掘的方块上的

Block.cs

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

public class Block : MonoBehaviour {
	int Health = 1;
	// Start is called before the first frame update
	void Start() {

	}

	// Update is called once per frame
	void Update() {
		if (Health <= 0) {
			Destroy(this.gameObject);
		}
	}
	private void OnTriggerEnter(Collider other) {
		if (other.tag == "Bullet") {
			Health--;
		}
	}
}

下面的设置：

        被挖掘方块的设置：

这里加两个碰撞体是因为角色也需要碰撞体，如果不打“Is Trigger”会检测不到，打上角色就会掉下去了，所以两个都得加。

 由于用的是碰撞检测，所以我们需要附加碰撞体，添加“FirePoint”检测器。

 子弹设置：

调试时一定要确保子弹轨迹要在游戏准心内。
