介绍
游戏中有非常多的计时功能,比如:各种cd,以及需要延时调用的方法;
一般实现有一下几种方式:
1.手动计时
float persisttime = 10f float starttime = time.time; if(time.time - starttime > persisttime) { debug.log("计时结束"); } float curtime = 0; curtime += time.deltatime; if(curtime > persisttime) { debug.log("计时结束"); }
2.协程
private float persisttime = 10f; ienumerator delayfunc() { yield return persisttime; debug.log("计时结束"); } private void start() { startcoroutine(delayfunc()); }
3.invoke回调
private void start() { invoke("delayfunc", persisttime); }
计时器功能
计时是为了到特定的时间,执行某个功能或方法;
计时器(timer):设计了计时暂停,计时重置,计时开始方法,计时中方法,计时结束方法,固定间隔调用方法,计时器可设置复用或单次;
计时管理器(timerma):负责倒计时,以及执行计时器方法;
代码:
using system; using system.collections.generic; using unityengine; using object = system.object; public class timer { public delegate void intervalact(object args); //总时间和当前持续时间 private float curtime = 0; private float totaltime = 0; //激活 public bool isactive; //计时结束是否销毁 public bool isdestroy; //是否暂停 public bool ispause; //间隔事件和间隔事件——dot private float intervaltime = 0; private float curinterval = 0; private intervalact oninterval; private object args; //进入事件 public action onenter; private bool isonenter = false; //持续事件 public action onstay; //退出事件 public action onend; public timer(float totaltime, bool isdestroy = true, bool ispause = false) { curtime = 0; this.totaltime = totaltime; isactive = true; this.isdestroy = isdestroy; this.ispause = ispause; timerma.i.addtimer(this); } public void run() { //暂停计时 if (ispause || !isactive) return; if (onenter != null) { if (!isonenter) { isonenter = true; onenter(); } } //持续事件 if (onstay != null) onstay(); curtime += time.deltatime; //间隔事件 if (oninterval != null) { curinterval += time.deltatime; if (curinterval > intervaltime) { oninterval(args); curinterval = 0; } } //计时结束 if (curtime > totaltime) { curtime = 0; isactive = false; if (onend != null) { onend(); } } } //设置间隔事件 public void setinterval(float interval, intervalact intervalfunc, object args = null) { this.intervaltime = interval; oninterval = intervalfunc; curinterval = 0; this.args = args; } //重置计时器 public void reset() { curtime = 0; isactive = true; ispause = false; curinterval = 0; isonenter = false; } //获取剩余时间 public float getremaintime() { return totaltime - curtime; } }
using system; using system.collections; using system.collections.generic; using unityengine; public class timerma : monobehaviour { #region 单例 private static timerma instance; timerma() {} public static timerma i { get { if (instance == null) instance = new timerma(); return instance; } } #endregion private list<timer> timerlist; private void awake() { instance = this; timerlist = new list<timer>(); } public void addtimer(timer t) { timerlist.add(t); } void update() { for (int i = 0; i < timerlist.count;) { timerlist[i].run(); //计时结束,且需要销毁 if(!timerlist[i].isactive && timerlist[i].isdestroy) timerlist.removeat(i); else ++i; } } }
测试计时器
using system.collections; using system.collections.generic; using unityengine; using unityengine.ui; using object = system.object; public class test : monobehaviour { public text mtext1; public text mtext2; private timer timer; private int count = 0; void start() { timer = new timer(5f,false); timer.setinterval(1f, oninterval); timer.onenter = onstart; timer.onend = onexit; } void update() { debug.log(count); mtext1.text = timer.getremaintime().tostring("f2"); if (input.getkeydown(keycode.a)) { if (!timer.ispause) { timer.ispause = true; mtext2.text = "暂停计时"; } } if (input.getkeydown(keycode.s)) { if (timer.ispause) { timer.ispause = false; mtext2.text = "取消暂停计时"; } } if (input.getkeydown(keycode.d)) { timer.reset(); mtext2.text = "重置计时"; } } private void onstart() { mtext2.text = "开始计时"; } private void onexit() { mtext2.text = "结束计时"; } private void oninterval(object value) { count++; mtext2.text = $"间隔事件调用{count}"; } }
