计时器效果图：
Timer用法：
第一种：脚本加到物体上，勾选"自动计时"。
第二种：脚本加到物体上，调用timer.start()方法启动。
第三种：代码中动态添加Timer脚本。
using UnityEngine;
public class TimerTest : MonoBehaviour {
private void Start () {
// 创建一个Timer并开始计时
gameObject.AddComponent<Timer>().start(1.5f, onTimeup);
// 倒计时3秒
gameObject.AddComponent<Timer>().start(1, 3, onCD, onCDEnd);
// 无限计数(repeatCount为<=0时 无限重复)
gameObject.AddComponent<Timer>().start(1, -1, onCount, null);
// Timer API
Timer timer = gameObject.AddComponent<Timer>();
timer.delay = 10;// 延迟10秒开始
timer.start(); // 开始计时
timer.stop(); // 暂停计时
timer.reset(); // 重置已计时的时间和次数
timer.restart();// 重新开始计时 reset() + start()
}
/// <summary> 正常计时 </summary>
private void onTimeup(Timer timer) {
print("计时完成");
}
/// <summary> 倒计时间隔 </summary>
private void onCD(Timer timer) {
print(timer.repeatCount - timer.currentCount); // 3, 2, 1
}
/// <summary> 倒计时结束 </summary>
private void onCDEnd(Timer timer) {
print(timer.repeatCount - timer.currentCount); // 0
}
/// <summary> 无限计数 </summary>
private void onCount(Timer timer) {
print(timer.currentCount); // 1, 2, 3……
}
}Timer API：
// 开始/继续计时
public void start() {}
// 暂停计时
public void stop() {}
// 停止Timer并重置数据
public void reset() {}
// 重置数据并重新开始计时
public void restart() {}
// 开始计时 time时间(秒) onComplete(Timer timer)计时完成回调事件
public void start(float time, TimerCallback onComplete) {}
// 开始计时 interval计时间隔 repeatCount重复次数 onComplete(Timer timer)计时完成回调事件
public void start(float interval, int repeatCount, TimerCallback onComplete) {}
// 开始计时 interval计时间隔 repeatCount重复次数
// onInterval(Timer timer)计时间隔回调事件
// onComplete(Timer timer)计时完成回调事件
public void start(float interval, int repeatCount, TimerCallback onInterval, TimerCallback onComplete) {}Timer.cs
