模拟帧频率。。。

int runTime=1000*5;

        int FrameRate=1000/6;

        int checkTime=FrameRate;

        

        long startTime=new Date().getTime();

        while(runTime>checkTime)

        {

            //checkValue=moveVector3(90, checkValue);

            //checkValue.print();

            checkTime+=FrameRate;

            System.out.println(checkTime);

            try {

                Thread.sleep(FrameRate);

            } catch (InterruptedException e) {

                e.printStackTrace();

            }

        }

        long endTime=new Date().getTime();

        System.out.println(endTime-startTime);
