Cocos Creator之Scheduler

一, 每个脚本,即继承自cc.Component的都自带一个Scheduler计时器

const {ccclass, property} = cc._decorator;

@ccclass
export default class DemoLocalTimer extends cc.Component {

    start() {
        //永久执行 0秒后执行(立即执行) , 1S执行一次
        this.schedule(this.onTimer, 1, cc.macro.REPEAT_FOREVER, 0);
        //10S后执行一次
        this.scheduleOnce(this.onOnceTimer,10);
    }

    private onTimer(): void {
        cc.log(`%c永久: onTimer ` , "color:#a00;");
    }

    private onOnceTimer(): void {
        cc.log(`%c一次: onOnceTimer ` , "color:#00");
    }

    protected onDestroy() {
        this.unschedule(this.onTimer);//remove onTimer 计时器
    }
}

运行结果

二, cc.director的计时器(相当于全局)

const {ccclass, property} = cc._decorator;

@ccclass
export default class DemoTimer extends cc.Component {
    private _scheduler: cc.Scheduler;

    start() {
        this._scheduler = cc.director.getScheduler();
        this._scheduler.enableForTarget(this);//必须使用enableForTarget注册Id不然会报错
        //延迟3秒后，输出1，此后每1秒输出1，重复3次。一共输出1+3次
        this._scheduler.schedule(this.test1, this, 1, 3,3, false);
        //延迟3秒后，输出1，此后每1秒输出1，无限重复
        this._scheduler.schedule(this.test2, this, 1, cc.macro.REPEAT_FOREVER,3, false);
    }

    private test1(){
        console.log("test1");
    }

    private test2(){
        console.log("test2");
    }
    protected onDestroy(): void{
        this._scheduler.unscheduleAll();//删除绑定的所有计时器
        //this._scheduler.unschedule(this.test1,this);//remove test1 计时器
        //this._scheduler.unschedule(this.test2,this);//remove test2 计时器
    }
}

运行结果
