[英]Java Swing Timer and Animation: how to put it together
我将重新发布此问题,以使其更加精确,希望我能得到一些帮助,因为这使我发疯。 我正在开发一个最多可容纳6名玩家的棋盘游戏,每个玩家都有一个不同的彩色棋子。 我将以下图像加载到BufferedImage数组中,将其视为精灵:
这是相对的代码,将每个有色骰子的每个面放在BufferedImage []中的某个位置:
private BufferedImage[] initAnimationBuffer() {
BufferedImage[] result = new BufferedImage[36];
for (int i = 0; i < 6; i++) {
for (int j = i; j < 6 + i; j++)
result[i + j] = DieSprite.getSprite(j, i, 0);
}
return result;
}
然后,根据玩家的颜色,每个玩家还将具有以下矩阵,该矩阵包含根据获得的骰子值/位置的其颜色的面孔。 换句话说,此矩阵包含图像的“一行”,并按值索引:
private BufferedImage[][] initExactDieFaces() {
BufferedImage[][] result = new BufferedImage[6][1];
int row = -1;
String myColor = this.coreGame.getMyPartecipant().getColor();
if (myColor.equals(Constants.COLOR[0])) {
row = 0;
} else if (myColor.equals(Constants.COLOR[1])) {
row = 2;
} else if (myColor.equals(Constants.COLOR[2])) {
row = 4;
} else if (myColor.equals(Constants.COLOR[3])) {
row = 1;
} else if (myColor.equals(Constants.COLOR[4])) {
row = 5;
} else if (myColor.equals(Constants.COLOR[5])) {
row = 3;
}
int offset = 0;
for (int i = 0; i < 6; i++) {
result[i][0] = DieSprite.getSprite(row, i, offset);
offset += 2;
}
return result;
}
我想要的是以下内容:-当按下“翻转模具”按钮时,我希望(例如)在JPanel内的特定JLabel中显示20个随机模具表面(它们应从第一个数组AnimationBuffer中获取) -上一个动画完成后,我希望显示骰子启动的获得结果(根据从ExcatDieFaces中获取的颜色棋子)。
要了解这一点,我知道我需要Swing计时器,但是我无法将它们全部放在一起。 这是startAnimationDie方法的一些代码,当按下“ flip die”按钮时会调用该代码:
private void startAnimationDie(final JPanel dieContainer) {
final BufferedImage[] animationBuffer = initAnimationBuffer();
final BufferedImage[][] exactDieFaces = initExactDieFaces();
final AnimationSprite animation = new AnimationSprite(
animationBuffer, Constants.DIE_ANIMATION_SPEED);
/* getting launch value fromt the core Game */
int launchResult = coreGame.launchDie();
coreGame.getMyPartecipant().setLastLaunch(launchResult);
final Timer timer = new Timer(250, new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
dieContainer.removeAll();
dieContainer.updateUI();
animation.start();
JLabel resultDie = new JLabel();
resultDie.setBounds(60, 265, Constants.DIE_SIZE,Constants.DIE_SIZE);
resultDie.setIcon(new ImageIcon(animationBuffer[new Random().nextInt(36)]));
dieContainer.add(resultDie);
dieContainer.updateUI();
updateUI();
repaint();
}
});
/* animation begins, rolling faces are shown each time the Timer ends*/
for(int i = 0; i<20; i++)
timer.start()
/* showing the final face according to the pawn color and the obtained result from the launch */
dieContainer.removeAll();
dieContainer.updateUI();
AnimationSprite resultAnimation = new AnimationSprite(exactDieFaces[launchResult - 1], 6);
resultAnimation.start();
resultAnimation.update();
resultDie.setIcon(new ImageIcon(exactDieFaces[launchResult - 1][0]));
resultDie.setBounds(60, 265, Constants.DIE_SIZE, Constants.DIE_SIZE);
dieContainer.add(resultDie);
dieContainer.updateUI();
dieContainer.repaint();
}
我该如何运作? 我认为我应该使用Swing.invokeAndWait,但是我无法将所有内容放在一起...您能帮忙吗?
updateUI
,除非您要安装外观,否则不会按照您认为的那样做(这是非常低效的) icon
属性 Timer
,允许它增加一个计数器,这样您就知道它被调用了多少次,并在每个刻度上更新了骰子滚动和计数器。 将Timer
视为一种循环,在每次迭代(滴答)中,您需要做一些事情(例如增加计数器)
(注意-当模具看起来已经“停滞”时,这是因为图像显示的顺序要多于一次。您可以通过将所有图像放入List
并使用Collections.shuffle
来解决这个问题。执行三次) ,将结果添加到另一个List
应该会给您24个无重复的序列(好的,它可能会在边界上重复,但是最好使用Math.random
