Java-更改計時器的運行時間

Question

我有一個Timer ，它為TimerTask安排了delay 0和period 150。現在，我想更改period ，但是Timer已在運行。 我現在如何更改period ？

private int penultimateStep = 1;
private int lastStep = 1;
private Timer move = new Timer();
private TimerTask movePlayer = new TimerTask(){
    public void run(){
        //Schritte ändern
        if(lastStep==3){
            lastStep = 2;
            penultimateStep = 1;
        }
        else if(lastStep==1){
            lastStep = 2;
            penultimateStep = 3;
        }
        else if(lastStep==2){
            if(penultimateStep==1){
                lastStep = 1;
                penultimateStep = 3;
            }
            else if(penultimateStep==3){
                lastStep = 3;
                penultimateStep = 1;
            }
        }
    }
};


...

move.schedule(movePlayer, 0, 150);

Timer和TimerTask-如何從TimerTask運行中重新安排計時器

可重置Java計時器

檢查兩個鏈接。 這個問題可能是以上任何一個的重復。

因此，您可以如下修改代碼：

private int penultimateStep = 1;
private int lastStep = 1;
private Timer move = new Timer();

class MovePlayer extends TimerTask {
   public void run(){
       //Schritte ändern
       if(lastStep==3){
           lastStep = 2;
           penultimateStep = 1;
        }
        else if(lastStep==1){
            lastStep = 2;
            penultimateStep = 3;
        }
        else if(lastStep==2){
            if(penultimateStep==1){
                lastStep = 1;
                penultimateStep = 3;
            }
            else if(penultimateStep==3){
                lastStep = 3;
                penultimateStep = 1;
            }
        }
    }
}


...

move.schedule(new MovePlayer(), 0, 150);

干杯。
