1，灵感来源

今天手头的工作忙完了，就等着服务器那边完活，于是开始研究同步问题。

正好想到之前想做的，两个小人对线PK，便有了这篇文章。

2，要实现的效果

如图所示，两个小人可以互相锁定，模拟真实对战，视线一直不离开对方。

最终实现效果：

套皮之后的效果：

3，基本实现原理

LookAt ：保持一直看着对面

RotateAround：绕着XX物体旋转

Translate：绕着某个方向前进后退

4，基本实现方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class test : MonoBehaviour
{public Transform targetTrans;public float spd = 180f;public float spd2 = 0.02f;public bool isOne = true;// Start is called before the first frame updatevoid Start(){}// Update is called once per framevoid Update(){transform.LookAt(targetTrans);if (isOne){if (Input.GetKey(KeyCode.A)){this.transform.RotateAround(targetTrans.position, Vector3.up, spd * Time.deltaTime);}if (Input.GetKey(KeyCode.D)){this.transform.RotateAround(targetTrans.position, Vector3.up, -spd * Time.deltaTime);}if (Input.GetKey(KeyCode.W)){transform.Translate(spd2 * Vector3.forward * Time.time, Space.Self);}if (Input.GetKey(KeyCode.S)){transform.Translate(-spd2 * Vector3.forward * Time.time, Space.Self);}}else{if (Input.GetKey(KeyCode.RightArrow)){this.transform.RotateAround(targetTrans.position, Vector3.up, spd * Time.deltaTime);}if (Input.GetKey(KeyCode.LeftArrow)){this.transform.RotateAround(targetTrans.position, Vector3.up, -spd * Time.deltaTime);}if (Input.GetKey(KeyCode.UpArrow)){transform.Translate(spd2 * Vector3.forward * Time.time, Space.Self);}if (Input.GetKey(KeyCode.DownArrow)){transform.Translate(-spd2 * Vector3.forward * Time.time, Space.Self);}}}
