Unity計時器腳本Timer

計時器效果圖：

Timer用法：
第一種：腳本加到物體上，勾選"自動計時"。
第二種：腳本加到物體上，調用timer.start()方法啓動。
第三種：代碼中動態添加Timer腳本。

using UnityEngine;

public class TimerTest : MonoBehaviour {

    private void Start () {
        // 建立一個Timer並開始計時
        gameObject.AddComponent<Timer>().start(1.5f, onTimeup);

        // 倒計時3秒
        gameObject.AddComponent<Timer>().start(1, 3, onCD, onCDEnd);

        // 無限計數(repeatCount爲<=0時 無限重複)
        gameObject.AddComponent<Timer>().start(1, -1, onCount, null);

        // Timer API
        Timer timer = gameObject.AddComponent<Timer>();
        timer.delay = 10;// 延遲10秒開始
        timer.start();  // 開始計時
        timer.stop();   // 暫停計時
        timer.reset();  // 重置已計時的時間和次數
        timer.restart();// 從新開始計時 reset() + start()
    }

    /// <summary> 正常計時 </summary>
    private void onTimeup(Timer timer) {
        print("計時完成");
    }

    /// <summary> 倒計時間隔 </summary>
    private void onCD(Timer timer) {
        print(timer.repeatCount - timer.currentCount); // 3, 2, 1
    }

    /// <summary> 倒計時結束 </summary>
    private void onCDEnd(Timer timer) {
        print(timer.repeatCount - timer.currentCount); // 0
    }

    /// <summary> 無限計數 </summary>
    private void onCount(Timer timer) {
        print(timer.currentCount); // 1, 2, 3……
    }

}

Timer API：

// 開始/繼續計時
public void start() {}

// 暫停計時
public void stop() {}

// 中止Timer並重置數據
public void reset() {}

// 重置數據並從新開始計時
public void restart() {}

// 開始計時 time時間(秒) onComplete(Timer timer)計時完成回調事件
public void start(float time, TimerCallback onComplete) {}

// 開始計時 interval計時間隔 repeatCount重複次數 onComplete(Timer timer)計時完成回調事件
public void start(float interval, int repeatCount, TimerCallback onComplete) {}

// 開始計時 interval計時間隔 repeatCount重複次數
// onInterval(Timer timer)計時間隔回調事件
// onComplete(Timer timer)計時完成回調事件
public void start(float interval, int repeatCount, TimerCallback onInterval, TimerCallback onComplete) {}
