我工作的一個學院項目在JavaFX的：像太空Invaders.I一個遊戲試圖讓每個OVNI的一個ParallelTransition動畫，營造出的TimeLine動畫並將其添加到每個人的ParallelTransition中，爲每個人管理一個EventHandler，以便將ovni移動到X位置並在Y到達窗口的左邊界時移動。問題是當我在播放動畫時，只有第一行在x位置正確移動，但其他行不是。換句話說，當其他行在x位置上移動一段距離時，它們不會在邊界上移動，而是移動到Y位置。結果如下：運動問題8

這是方法第二，我已經爲ovnis聲明瞭兩個矩陣：一個用於Panes的矩陣，它將包含每個ovni的形狀;和其他將包含ovni對象。

public Juego(){ 
    lab=new Label(); 
    transicionEnY=new ParallelTransition(); 
    dir=new File(Constantes.GAME_BACKGROUND); 
    Pane navePane=new Pane(); 
    paneOvnis=new Pane[3][6]; //the panes for each ovni´s shape 
    nave=new Nave(navePane); 
    gameContainer=new Pane(); 
    gameContainer.getChildren().addAll(navePane); 
    background=new Image(dir.toURI().toString()); 
    pane=new BorderPane(); 
    pane.setCenter(gameContainer); 
    pane.setBackground(new Background(new BackgroundImage(background,null,null,null,new BackgroundSize(Constantes.MAXIMUM_WIDHT,Constantes.MAXIMUM_HEIGTH,false,false,false,true)))); 
    //playMusic(); 
    agregarOvnis(); 
    moverOvnis(); 
    pane.setBottom(lab); 
}

來填充每個矩陣的方法：

public void agregarOvnis(){ 
    this.ovnis=new Ovni[paneOvnis.length][paneOvnis[0].length]; 
    for(int i=0;i<paneOvnis.length;i++){ 
     for(int j=0;j<paneOvnis[0].length;j++){  
      Pane paneOvni=new Pane(); 
      Ovni ovni=new OvniGris(paneOvni); 
      ovni.setLocation(Constantes.POS_OVNI_X+Constantes.OVNI_SPACING_X*j,Constantes.POS_OVNI_Y+Constantes.OVNI_SPACING_Y*i); 
      this.gameContainer.getChildren().add(paneOvni); 
      this.paneOvnis[i][j]=paneOvni; 
      this.ovnis[i][j]=ovni; 
     } 
    } 
}

，使聲明ParallelTransition和使時間軸動畫每個OVNI的方法：

public void moverOvnis(){ 
    ParallelTransition animaciones=new ParallelTransition(); 
    for(int i=0;i<ovnis.length;i++){ 
     for(int j=0;j<ovnis[i].length;j++){ 
      Timeline animacionOvnis=new Timeline(); 
      KeyFrame kf=new KeyFrame(Duration.millis(900),new ManejadorMovimientos(i,j)); 
      animacionOvnis.getKeyFrames().add(kf); 
      animacionOvnis.setCycleCount(Timeline.INDEFINITE); 
      animacionOvnis.setAutoReverse(false); 
      animaciones.getChildren().add(animacionOvnis); 
     } 
    } 
    animaciones.play(); 
}

最後，這是在時間軸事件處理程序類以使每個ovni的ovni運動：

private class ManejadorMovimientos implements EventHandler<ActionEvent>{ 

    int i; 
    int j; 
    int orientacion=1; 

    public ManejadorMovimientos(int i, int j){ 
     this.i=i; 
     this.j=j; 
    } 

    @Override 
    public void handle(ActionEvent event) { 
     double distanciaMaxDer=maxDistanceRight(); 
     double distanciaMaxIzq=maxDistanceLeft(); 
     lab.setText(""+distanciaMaxDer+","+ovnis[0][5].getXLocation()); 
     if(orientacion==1) 
      if(distanciaMaxDer-30>0){ 
      ovnis[i][j].setLocation(ovnis[i][j].getXLocation()+30,ovnis[i][j].getYLocation()); 
      } 
      else{ 
      ovnis[i][j].setLocation(ovnis[i][j].getXLocation(),ovnis[i][j].getYLocation()+20); 
      orientacion=-1;     
      } 
     else{ 
      if(distanciaMaxIzq-30>30){ 
      ovnis[i][j].setLocation(ovnis[i][j].getXLocation()-30,ovnis[i][j].getYLocation()); 
      } 
      else{ 
      ovnis[i][j].setLocation(ovnis[i][j].getXLocation(),ovnis[i][j].getYLocation()+20); 
      orientacion=1; 
      } 
     } 

    } 

    private double maxDistanceRight(){ 
     int j=ovnis[0].length-1; 
     while(j>=0){ 
      for(int i=0;i<ovnis.length;i++){ 
       if(ovnis[i][j]!=null){ 
        return 1.25*Constantes.MAXIMUM_WIDHT-ovnis[i][j].getXLocation(); 
       } 
      } 
      j--; 
     } 
     return -1; 
    } 

    private double maxDistanceLeft(){ 
     int j=0; 
     while(j<ovnis[0].length){ 
      for(int i=0;i<ovnis.length;i++){ 
       if(ovnis[i][j]!=null){ 
        return ovnis[i][j].getXLocation()-30; 
       } 
      } 
      j++; 
     } 
     return -1; 
    } 

}

我分別離開這裏的常量，OVNI和遊戲類，以瞭解更多信息（在西班牙語對不起，有些話，我的it's項目的requeriments的一部分。）

你更新由線的位置線，每次重新計算最右邊的位置。在您將Timeline s添加到ParallelTransition的順序中，右上角的ouvi在更新下ouvis之前更新，這意味着ouvis會考慮在最上面的ouvis之前的一個「幀」之前到達最右邊的位置，問題。

其他備註：

在這種情況下使用ParallelTransition是不必要/低效的，因爲單個Timeline可以處理所有的KeyFrame秒。此外，即使多個KeyFrame是不必要的，因爲ouvis全部在同一時間被更新，並且甚至一些值應該被重用。

下面的例子到處移動簡單的對象：

private Rectangle[][] rects = new Rectangle[3][3]; 

private void moveDown() { 
    for (Rectangle[] column : rects) { 
     for (Rectangle r : column) { 
      if (r != null) { 
       r.setY(r.getY() + 5); 
      } 
     } 
    } 
} 

@Override 
public void start(Stage primaryStage) { 
    Pane root = new Pane(); 
    for (int j = 0; j < rects.length; j++) { 
     Rectangle[] column = rects[j]; 
     for (int i = 0; i < column.length; i++) { 
      Rectangle rect = new Rectangle(20, 20); 
      rect.setX(j * 25); 
      rect.setY(i * 25); 
      root.getChildren().add(rect); 
      column[i] = rect; 
     } 
    } 
    Timeline timeline = new Timeline(new KeyFrame(Duration.millis(500), new EventHandler<ActionEvent>() { 

     boolean movingRight = true; 

     @Override 
     public void handle(ActionEvent event) { 
      double maxX = Double.NEGATIVE_INFINITY; 
      double minX = Double.POSITIVE_INFINITY; 
      outer: 
      for (int i = rects.length - 1; i >= 0; i--) { 
       for (Rectangle r : rects[i]) { 
        if (r != null) { 
         maxX = r.getX() + r.getWidth(); 
         break outer; 
        } 
       } 
      } 
      outer: 
      for (Rectangle[] col : rects) { 
       for (Rectangle r : col) { 
        if (r != null) { 
         minX = r.getX(); 
         break outer; 
        } 
       } 
      } 
      if (movingRight) { 
       if (maxX + 5 > 150) { 
        moveDown(); 
        movingRight = false; 
        return; 
       } 
      } else { 
       if (minX - 5 < 0) { 
        moveDown(); 
        movingRight = true; 
        return; 
       } 
      } 
      double dx = movingRight ? 5 : -5; 
      for (Rectangle[] column : rects) { 
       for (Rectangle r : column) { 
        if (r != null) { 
         r.setX(r.getX() + dx); 
        } 
       } 
      } 
     } 

    })); 
    timeline.setCycleCount(Animation.INDEFINITE); 
    timeline.play(); 

    Scene scene = new Scene(root, 150, 600); 

    primaryStage.setScene(scene); 
    primaryStage.show();
