go訂時器使用

 定義定時器

func callByTimeID(timerId string, tick time.Duration,callback func())  {
  ticker := time.NewTicker(time.Second)
  defer ticker.Stop()
  done := make(chan bool)
  go func() {
    time.Sleep(tick)
    done <- true
  }()
  for {
    select {
    case <-done:
      fmt.Println("Done!")
      callback()
      return
    case t := <-ticker.C:
       fmt.Println(fmt.Sprintf("TimerId:%s,Date: %v-%v-%v Time: %v:%v:%v",
         timerId,t.Year(),t.Month(),t.Day(),t.Hour(),t.Minute(),t.Second()))
    }
  }
}

使用定時器：

func TickDemo()  {
    fmt.Println("Time Tick Test.")
}

func main() {
    callByTimeID("GAME_BEGIN_CLOCK",5 * time.Second,TickDemo)

}

輸出：

TimerId:GAME_BEGIN_CLOCK,Date: 2021-September-9 Time: 15:31:55
TimerId:GAME_BEGIN_CLOCK,Date: 2021-September-9 Time: 15:31:56
TimerId:GAME_BEGIN_CLOCK,Date: 2021-September-9 Time: 15:31:57
TimerId:GAME_BEGIN_CLOCK,Date: 2021-September-9 Time: 15:31:58
TimerId:GAME_BEGIN_CLOCK,Date: 2021-September-9 Time: 15:31:59
Done!
Time Tick Test.
