5-5 Player Health 角色的生命值

学习如何通过脚本来管理玩家的生命值，比如受到攻击或者死亡
PlayerHealth
C#

using UnityEngine;
using System.Collections;
public class PlayerHealth : MonoBehaviour
{
public float health = 100f; // 设置玩家现存的血量.
public float resetAfterDeathTime = 5f; // 从死亡后到关卡重新开始的时间.
public AudioClip deathClip; // 玩家死亡播放的声音.
private Animator anim; // Animator动画控制器变量.
private PlayerMovement playerMovement; // PlayerMovement变量.
private HashIDs hash; // HashIDs变量.
private SceneFadeInOut sceneFadeInOut; // SceneFadeInOut变量.
private LastPlayerSighting lastPlayerSighting; // LastPlayerSighting变量.
private float timer; // 玩家死亡计时器.
private bool playerDead; // 死亡标志位.
void Awake ()
{
// 初始化变量.
anim = GetComponent<Animator>();
playerMovement = GetComponent<PlayerMovement>();
hash = GameObject.FindGameObjectWithTag(Tags.gameController).GetComponent<HashIDs>();
sceneFadeInOut = GameObject.FindGameObjectWithTag(Tags.fader).GetComponent<SceneFadeInOut>();
lastPlayerSighting = GameObject.FindGameObjectWithTag(Tags.gameController).GetComponent<LastPlayerSighting>();
}
void Update ()
{
// 如果玩家的血小于 0...
if(health <= 0f)
{
// ... ... 这个时候玩家中枪了还没死.
if(!playerDead)
// ... 那就执行玩家死亡函数.
PlayerDying();
else
{
// 否则, 玩家已经死了则执行.
PlayerDead();
LevelReset();
}
}
}
void PlayerDying ()
{
// 玩家还没死绝，奄奄一息，还在交党费,那就修改标志位宣布他死亡
playerDead = true;
// 设置玩家死亡动画
anim.SetBool(hash.deadBool, playerDead);
// 播放玩家死亡播放的声音.
AudioSource.PlayClipAtPoint(deathClip, transform.position);
}
void PlayerDead ()
{
// 判断玩家当前是不是已经播放了死亡动画，如果已经播放，则修改标志位.
if(anim.GetCurrentAnimatorStateInfo(0).nameHash == hash.dyingState)
anim.SetBool(hash.deadBool, false);
// 禁止移动.
anim.SetFloat(hash.speedFloat, 0f);
playerMovement.enabled = false;
// 游戏的警告状态解除.
lastPlayerSighting.position = lastPlayerSighting.resetPosition;
// 脚步声关闭.
audio.Stop();
}
void LevelReset ()
{
// 计时器.
timer += Time.deltaTime;
//死亡时间满足重新开始玩的时间...
if(timer >= resetAfterDeathTime)
// ... 关卡重新开始.
sceneFadeInOut.EndScene();
}
public void TakeDamage (float amount)
{
// 玩家减血.
health -= amount;
}
}
