Unity計(jì)時(shí)器腳本Timer的用法案例

小編給大家分享一下Unity計(jì)時(shí)器腳本Timer的用法案例，希望大家閱讀完這篇文章后大所收獲，下面讓我們一起去探討吧！

計(jì)時(shí)器效果圖：

Timer用法：
第一種：腳本加到物體上，勾選"自動(dòng)計(jì)時(shí)"。
第二種：腳本加到物體上，調(diào)用timer.start()方法啟動(dòng)。
第三種：代碼中動(dòng)態(tài)添加Timer腳本。

using UnityEngine;

public class TimerTest : MonoBehaviour {

    private void Start () {
        // 創(chuàng)建一個(gè)Timer并開(kāi)始計(jì)時(shí)
        gameObject.AddComponent<Timer>().start(1.5f, onTimeup);

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

        // 無(wú)限計(jì)數(shù)(repeatCount為<=0時(shí) 無(wú)限重復(fù))
        gameObject.AddComponent<Timer>().start(1, -1, onCount, null);

        // Timer API
        Timer timer = gameObject.AddComponent<Timer>();
        timer.delay = 10;// 延遲10秒開(kāi)始
        timer.start();  // 開(kāi)始計(jì)時(shí)
        timer.stop();   // 暫停計(jì)時(shí)
        timer.reset();  // 重置已計(jì)時(shí)的時(shí)間和次數(shù)
        timer.restart();// 重新開(kāi)始計(jì)時(shí) reset() + start()
    }

    /// <summary> 正常計(jì)時(shí) </summary>
    private void onTimeup(Timer timer) {
        print("計(jì)時(shí)完成");
    }

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

    /// <summary> 倒計(jì)時(shí)結(jié)束 </summary>
    private void onCDEnd(Timer timer) {
        print(timer.repeatCount - timer.currentCount); // 0
    }

    /// <summary> 無(wú)限計(jì)數(shù) </summary>
    private void onCount(Timer timer) {
        print(timer.currentCount); // 1, 2, 3……
    }

}

Timer API：

// 開(kāi)始/繼續(xù)計(jì)時(shí)
public void start() {}

// 暫停計(jì)時(shí)
public void stop() {}

// 停止Timer并重置數(shù)據(jù)
public void reset() {}

// 重置數(shù)據(jù)并重新開(kāi)始計(jì)時(shí)
public void restart() {}

// 開(kāi)始計(jì)時(shí) time時(shí)間(秒) onComplete(Timer timer)計(jì)時(shí)完成回調(diào)事件
public void start(float time, TimerCallback onComplete) {}

// 開(kāi)始計(jì)時(shí) interval計(jì)時(shí)間隔 repeatCount重復(fù)次數(shù) onComplete(Timer timer)計(jì)時(shí)完成回調(diào)事件
public void start(float interval, int repeatCount, TimerCallback onComplete) {}

// 開(kāi)始計(jì)時(shí) interval計(jì)時(shí)間隔 repeatCount重復(fù)次數(shù)
// onInterval(Timer timer)計(jì)時(shí)間隔回調(diào)事件
// onComplete(Timer timer)計(jì)時(shí)完成回調(diào)事件
public void start(float interval, int repeatCount, TimerCallback onInterval, TimerCallback onComplete) {}
