在一个JPanel多个动画（线程） [英] Multiple animations(threads) in a JPanel
问题描述
我试图code在Java中的棋盘游戏。
I am trying to code a board game in Java.
我有11类，包括主。董事会类继承JPanel，并提请董事会图像以及骰子形象。类播放器延伸JCoponent和实现Runnable（线程）。每个球员的实例是，它是全线移动棋子的动画。玩家级借鉴了主板上的棋子。
I have 11 classes including Main. Board class which extends JPanel and draws the board image as well as the dice image. The class Player which extends JCoponent and implements Runnable(Thread). Every player instance is a pawn-animation that it is moving across the board. The player class draws the pawn on the board.
模式的结果
如何code，它看起来像：结果
Pattern
How the code it looks like :
Board b=new Board();
Player p=new Player();
b.add(p);
JPanel panel=new JPanel();
panel.add(b);
add(panel); //adding the panel to the frame.
问题是，我不能同时拥有一个以上的棋子在黑板上。我已经试图重新粉刷在另一个类中的所有玩家（非动画），但没有奏效。我也试过JLayeredPane的，但也许我做错了什么。不幸的是，我不能改变上面的图案，所以不要让这一建议。
The problem is that I can't have more than one pawn simultaneously on the board. I have already tried to re-paint all the players (as non-animation) in another class but it didn't work. I also tried JLayeredPane but maybe I am doing something wrong. Unfortunately, I can't change the above pattern so don't make this suggestion.
感谢您提前对您有所帮助。
Thank you in advance for your help.
P.S：我不能发表任何code，因为其巨大的。结果 P.P.S：进一步澄清会得到，如果你问我
编辑：我改我的问题。是有可能同时有两个动画同一面板上？如果答案是肯定的一个我..how能做到这一点？
I reform my question. Is it possible to have two animations simultaneously on the same panel? if the answer is a yes ..how I can do that?
推荐答案
这是最有可能的可能有许多组件移动的一次。要么使用javax.swing.Timer中的OU的SwingWorker为此工作。
It's most likely possible to have many components moving all at once. Either use javax.swing.Timer ou SwingWorker for this to work.
下面是显示你这一个简单的例子。它把在基板16棋子和随机移动他们从一个地方到另一个地方。
Here is a quick example showing you this. It puts 16 pawns on a board and moves them randomly from one place to another.
