Unity计时器
Demo展示
介绍
游戏中有非常多的计时功能，比如:各种cd,以及需要延时调用的方法；
一般实现有一下几种方式：
1.手动计时
float persistTime = 10f
float startTime = Time.time;
if(Time.time - startTime > persistTime)
{
Debug.Log("计时结束");
}
float curTime = 0;
curTime += Time.deltaTime;
if(curTime > persistTime)
{
Debug.Log("计时结束");
}
2.协程
private float persistTime = 10f;
IEnumerator DelayFunc()
{
yield return persistTime;
Debug.Log("计时结束");
}
private void Start()
{
StartCoroutine(DelayFunc());
}
3.Invoke回调
private void Start()
{
Invoke("DelayFunc", persistTime);
}
计时器功能
计时是为了到特定的时间，执行某个功能或方法；
计时器（Timer）：设计了计时暂停，计时重置，计时开始方法，计时中方法，计时结束方法，固定间隔调用方法，计时器可设置复用或单次；
计时管理器（TimerMa）：负责倒计时，以及执行计时器方法；
