如何使用 Swing 制作动画? [英] How to make an animation with Swing?

问题描述

我正在制作 JApplet，但遇到了动画问题.

I am making a JApplet and got stuck with a animation problem.

这是我的代码:

        this.sprite.setBounds(0,0,20,17);
        this.sprite.setIcon(this.rangerDown);
        for(int i = 0; i< 16;i++)
        {
            this.sprite.repaint();
            this.sprite.setLocation(this.sprite.getX(), this.sprite.getY()+10);
            try{
                Thread.currentThread().sleep(100);
            }catch(InterruptedException e){
            }
        }       

有了这个，就没有动画了:在循环过程中什么也没有发生，repaint() 方法似乎只在精灵停止移动时才起作用.

With this, there is no animation : nothing happens during the loop, the repaint() method seems to only act once the sprite stopped moving.

我只想为此使用 Swing，对如何进行有任何想法吗?

I would like to use only Swing for this, any ideas of how to proceed ?

推荐答案

您应该使用 javax.swing.Timer 来执行动画而不是线程休眠.这是一个很好的链接，可以帮助您:http://java.sun.com/docs/books/tutorial/uiswing/misc/timer.html

You should use a javax.swing.Timer to perform the animation rather than Thread sleeps. Here is a good link to get you going: http://java.sun.com/docs/books/tutorial/uiswing/misc/timer.html

另外，我强烈建议您购买肮脏的富客户——如果您访问该网站，您也可以下载所有示例代码都是免费的.例如，第 12 章:动画基础 有一些很好的例子，例如演示 Timer 用法的MovingButton.

Also I highly recommend buying the book Filthy Rich Clients -- if you go to the website you can also download all the example code for free. For example, Chapter 12: Animation Fundamentals has some great examples, such as MovingButton that demonstrates the Timer usage.
