SIKI学习——坦克大战07

1-敌人AI的优化，游戏测试

避免两个两个AI相撞在一起
将玩家的初始值设置为 private float v=-1;

在Enemy脚本里添加下面的代码

 /// <summary>
    /// 这里防止敌人扎堆，两个敌人碰撞
    /// </summary>
    /// <param name="collision"></param>
    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.tag=="Enemy")
        {
            timeValChangeDirection = 4;//一旦碰到就转向
        }
    }

2-玩家状态

游戏刚开始敌人往下走

 private float timeValChangeDirection;//用来改变方向 刚开始没有旋转直接向下移动

新建空物体PlayerManager并挂载PlayerManager脚本

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

public class PlayerManager : MonoBehaviour
{
    //属性值
    public int lifeValue = 3;
    public int playerScore = 0;
    public bool isDead;

    //引用
    public GameObject born;//拿到出生的特效

    //单例 全选private static PlayerManager instance;按住Ctrl不松，点击R E可以不全单例
    private static PlayerManager instance;
    public static PlayerManager Instance
    {
        get
        {
            return instance;
        }

        set
        {
            instance = value;
        }
    }
    private void Awake()
    {
        instance = this;//实例化一下单例
    }

    void Start ()
    {
		
	}
	
	void Update ()
    {
        if (isDead)
        {
            Recover();
        }
	}
    private void Recover()
    {
        if (lifeValue <= 0)
        {
            //游戏失败，返回主界面

        }
        else
        {
            lifeValue--;
            GameObject go = Instantiate(born, new Vector3(-2,-8,0),Quaternion.identity);
            go.GetComponent<Born>().createPlayer = true;
            isDead = false;
        }
    }
}

在Player脚本中让死亡为true

当击败敌人时获取得分
