【UNET自学日志】Part11 玩家复活

上一部分玩家摧毁的方法是设置其enable为false，那么玩家的复活就是在玩家死后，显示复活的按钮，点击按钮后把相关的enable再次设置为true即可

新建脚本Player_Respawn

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
using UnityEngine.UI;

public class Player_Respawn : NetworkBehaviour {

    private Player_Health healthScript;
    private Image crossHairImage;
    private GameObject respawnButton;

// Use this for initialization
void Start () 
    {
        healthScript = GetComponent<Player_Health>();
        healthScript.EventRespawn += EnablePlayer;
        crossHairImage = GameObject.Find("crossHairImage").GetComponent<Image>();
        SetRespawnButton();
}

    void SetRespawnButton()
    {
        if (isLocalPlayer)
        {
            respawnButton = GameObject.Find("GameManager").GetComponent<GameManager_References>().respawnButton;
            respawnButton.GetComponent<Button>().onClick.AddListener(CommenceRespawn);
            respawnButton.SetActive(false);
        }
    }

    void OnDisable()
    {
        healthScript.EventRespawn -= EnablePlayer;
    }

    void EnablePlayer()    
    {
        GetComponent<CharacterController>().enabled = true;
        GetComponent<Player_Shoot>().enabled = true;
        GetComponent<BoxCollider>().enabled = true;

        Renderer[] renderers = GetComponentsInChildren<Renderer>();
        foreach (Renderer ren in renderers)
        {
            ren.enabled = true;
        }

        if (isLocalPlayer)
        {
            GetComponent<UnityStandardAssets.Characters.FirstPerson.FirstPersonController>().enabled = true;
            crossHairImage.enabled = true;
            respawnButton.SetActive(false);
        }
    }

    void CommenceRespawn()
    {
        CmdRespawnOnServer();
    } 

    [Command]
    void CmdRespawnOnServer()
    {
        healthScript.ResetHealth();
    }
}

在Player_Health中添加几行代码

    public delegate void RespawnDelegate();
    public event RespawnDelegate EventRespawn;
    void CheckCondition()
    {
        if (health <= 0 && !shouldDie&&!isDead)
        {
            shouldDie = true;
        }

        if (health <= 0 && shouldDie)
        {
            if (EventDie != null)
            {
                EventDie();
            }

            shouldDie = false;
        }

        if (health > 0 && isDead)
        {
            if (EventRespawn != null)
            {
                EventRespawn();
            }

            isDead = false;
        }
    }
    public void ResetHealth()
    {
        health = 100;
    }

在Player_Death中的预留位置添加设置按钮活动的一行代码

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;
            GameObject.Find("GameManager").GetComponent<GameManager_References>().respawnButton.SetActive(true);
        }
    }
