Java - 使用ImageIcon的JLabel上的setLocation / Bounds不能使用另一个类

标签: java swing jframe jlabel imageicon

这是我的第一个问题,如果我能做得更好,请给我评论。

当我致电Hero.Move.MoveLeft();" JLabel" labelHero时不要在视觉上移动。但是调试器说posX发生了变化。 有趣的是,如果我在第一次添加gamePanel之前调用Hero.Move.MoveLeft();而不是它的工作。 (我在myWindow中间标记了位置。)

请求帮助人员。

package com.company.Game;

import com.company.Characters.Hero;

public class Main
{

    public static void main(String[] args)
    {
        Hero.Initialize();
        myWindow myWindow = new myWindow();
        PaintObjects.PaintNew();
        myWindow.Repaint();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
        Hero.Move.MoveLeft();
    }
}

Thx家伙,

我找到了问题。

PaintObjects.PaintNew();被召唤了两次。一次在main方法中,一次在myWindow构造函数中。程序如何失去与可见对象的连接。
