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);

修正延时

public static void main(String[] args)
    {
        int runTime=1000;
        int FrameRate=1000/6;
        int checkTime=FrameRate;
        long startTime,entTime;
       
        long checkSTime=new Date().getTime();
        int i=0;
        while(runTime>checkTime)
        {
            System.out.println(i);
            startTime =new Date().getTime();
            try {
                Thread.sleep(300);
            } catch (InterruptedException e1) {
                e1.printStackTrace();
            }
            entTime=new Date().getTime();
            
            long check=entTime-startTime;
            if(check<FrameRate)
                checkTime+=FrameRate;
            else
                checkTime+=check;
            i++;
            try {
                if(check<FrameRate)
                    Thread.sleep(FrameRate-check);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println("time : " +( new Date().getTime()-checkSTime));
        
    }
