游戏只会渲染一个敌人

Question

我正在尝试制作，以便在关卡屏幕上显示多个方块。由于某种原因，它所呈现的唯一方格将是我输入的顺序中的最后一个方格。在它处理了2个小时并且非常烦人。任何帮助都会很棒，非常感谢。

public class Level1 extends JFrame implements ActionListener, KeyListener {

    LevelRender render;
    static Square square;

    static Player player;
    static Square squares;
    public static Timer timer;
    boolean fail, Over, Reset = false, create = false;
    static int enemyCount = 5;

    static int eX = 200, eY, z;

    ArrayList <Enemys> squareList = new ArrayList();

    public static Level1 level;

    ImageIcon Level1 = new ImageIcon("C:\\Users\\Kyle\\Documents\\NetBeansProjects\\Testing52\\src\\testing52\\Level1.png");

    public Level1(Player player){        
        timer = new Timer(50,this);
        render = new LevelRender();        
        setVisible(true);
        setSize(1000,500);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        add(render);
        addKeyListener(this);        
        this.player = player; 
        timer.start();    
        player.x = 0;
