使用Java libgdx进行俄罗斯方块克隆

Question

我正在使用Java libgdx在俄罗斯方块克隆上工作，但我陷入了困境，如何使用矩形宽度40，每个框的高度40继承所有我的代码

  public ArrayList<DownBlocks> getBlocks() {
    return blocks;
}

public ArrayList<DownBlocks> getDones() {
    return dones;
}

private ArrayList<DownBlocks> blocks;
private ArrayList<DownBlocks> dones;

@Override
public void show() {



        blocks=new ArrayList<DownBlocks>();
        dones=new ArrayList<DownBlocks>();
        create();

    }

    @Override
    public void render(float delta) {
 if (stop||!stopdown){
            t=t+1;
            if (t>40){create();t=0;}
            outer: for(int i = 0; i < blocks.size(); ++i)
            {
                for(int j = 0; j < getDones().size(); ++j)
                {
                    if(blocks.get(i).y == getDones().get(j).y + 40&&
                            blocks.get(i).x == getDones().get(j).x)
                    {

                        continue outer;
                    }else stop=false;
                }
            }
        }
public void create(){



    getDones().addAll(getBlocks());
    getBlocks().clear();
         blocks.add(new DownBlocks(game, this, 240, 680, 40, 40,n,1));
        blocks.add(new DownBlocks(game, this, 200, 640, 40, 40,n,2));
        blocks.add(new DownBlocks(game, this, 200, 680, 40, 40,n,3));}

DownBlocks评估：

    public DownBlocks(MyGdxGame game, Gamescreen gamescreen, int x, int y, int width, int hight,int s,int local) {
        texture=new Texture("badlogic.jpg");
        this.y=y;
        this.s=s;
        this.local=local;
        this.x=x;
        this.width=width;
        this.height=hight;
        this.game=game;
        this.gamescreen=gamescreen;
        rotate=true;
    }
    public void render(){
        game.batch.begin();
        game.batch.draw(texture,x, y,width,height);
        game.batch.end();

        f=f+1;


        if (y<=0){stopdown=false;}
        else if (y>0){stopdown=true;}

        if (f >= 40) {
            if (y>0&&!gamescreen.stop&&gamescreen.stopdown){
            y = y - 40;f=0;}
        }
}}

我已经尝试过为Dones Array的每个对象使用for循环，但是我无法想象for循环
