【UNET自学日志】Part10 摧毁玩家

上一个部分做了玩家的射击造成的伤害，但是玩家生命值为负的时候玩家还在游戏场景上，这个部分我们将要把生命值为0以下的玩家摧毁掉

主要的思路就是当玩家的生命值小于或等于0的时候，将玩家的控制和渲染都设置为不可用即可

将Player_Health脚本做下修改

using UnityEngine;using System.Collections;using UnityEngine.Networking;using UnityEngine.UI;public class Player_Health : NetworkBehaviour {    //玩家的生命值，当生命值的数值发生变化时调用OnHealthChanged函数    [SyncVar(hook="OnHealthChanged")]private int health = 100;    //右下角显示生命值的Text    private Text healthText;    //判断玩家是否死亡的两个bool变量    private bool shouldDie = false;    public bool isDead = false;    public delegate void DieDelegate();    public event DieDelegate EventDie;void Start ()    {        healthText = GameObject.Find("Health Text").GetComponent<Text>();        SetHealthText();}void Update ()     {        CheckCondition();}    //检查条件    void CheckCondition()    {        if (health <= 0 && !shouldDie&&!isDead)        {            shouldDie = true;        }        if (health <= 0 && shouldDie)        {            if (EventDie != null)            {                EventDie();            }            shouldDie = false;        }    }    //设置生命值Text的内容    void SetHealthText()    {        if (isLocalPlayer)        {            healthText.text = "Health " + health.ToString();        }    }    //生命值减少    public void DeductHealth(int dmg)    {        health -= dmg;    }    //生命值改变    void OnHealthChanged(int hlth)    {        health = hlth;        SetHealthText();    }}

另新建一个脚本Player_Death

using UnityEngine;using System.Collections;using UnityEngine.Networking;using UnityEngine.UI;public class Player_Death : NetworkBehaviour {    private Player_Health healthScript;    //画面中心的小红点    private Image crossHairImage;void Start ()     {        crossHairImage = GameObject.Find("crossHairImage").GetComponent<Image>();        healthScript = GetComponent<Player_Health>();        healthScript.EventDie += DisablePlayer;}    void OnDisable()    {        healthScript.EventDie -= DisablePlayer;    }    //将Player的相关控制和渲染设置成不可用状态，以代表摧毁Player    void DisablePlayer()    {               GetComponent<CharacterController>().enabled=false;               GetComponent<Player_Shoot>().enabled = false;        GetComponent<BoxCollider>().enabled = false;        Renderer[] renderers = GetComponentsInChildren<Renderer>();        foreach (Renderer ren in renderers)        {            ren.enabled = false;        }        healthScript.isDead = true;        if (isLocalPlayer)        {            GetComponent<UnityStandardAssets.Characters.FirstPerson.FirstPersonController>().enabled = false;            crossHairImage.enabled = false;            //Respawan button 预留重生按钮，下个部分做        }    }}

其中用到了一个委托的方法，因为对委托不是很熟悉，也就不多说些误人子弟的话了。

按着某人的建议写了点注释= =为什么感觉那么鸡肋呢。。。
