关于u3d:U3D游戏开发框架五计时器

一：目标

游戏开发中，计时是一个常见的性能。比方技能的冷却工夫，角色的生命回复等等

个别的实现办法是通过协程或者 Invoke，然而这样并没有对立治理所有的计时器，所以咱们须要一个管理器对立治理计时器的相干操作

二：解决的问题及长处

——注册和登记计时器
——失去某一个计时器的倒计时剩余时间
——设置所有倒计时同步或异步

三：应用办法

——应用 TimerMgr.Ins.XXX

TimerMgr.Ins.RegisterTimer(3, () =>
 {Debug.Log("finish 1");
 }, "", true);
TimerMgr.Ins.RegisterTimer(4, () =>
{Debug.Log("finish 2");
}, "", true);
TimerMgr.Ins.UnRegisterAllTimer();
TimerMgr.Ins.UnRegisterTimer("Timer1");
TimerMgr.Ins.GetRemainTime("Timer1");

四：代码实现

                }
            }
        }
        else

            timerList[0].UpdateTimer(timerList[0].ignoreTimeScale ? realDeltaTime : Time.deltaTime);
            if (timerList[0].isFinish)
