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) {}
