我将再次发布这个问题,试图更精确,并希望我会得到一些帮助,因为这让我发疯。我正在开发一款最多有6名玩家的棋盘游戏,每个游戏都有不同颜色的棋子。我有下面的图像加载在BufferedImage数组中,将其视为精灵:
这是相对代码,将每个彩色模具的每个面放在BufferedImage []中的位置:
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;
}
然后每个玩家根据他的颜色,根据获得的模具值/位置,还将具有包含其颜色面的以下矩阵。换句话说,该矩阵包含图像的“一条线”,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个随机模具面(它们应该从第一个数组中获取,AnimationBuffer) - 上一个动画完成后,我想要显示获得的模具启动结果(根据颜色典当,取自ExcatDieFaces)。
为了得到这个,我知道我需要摆动计时器,但我无法将它们全部放在一起;这里是一些startAnimationDie方法的代码,当按下“翻转”按钮时调用该方法:
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();
}
我怎样才能让它发挥作用?我想我应该使用Swing.invokeAndWait但是我不能把所有的东西放在一起......你能帮忙吗?
答案 0 :(得分:5)
updateUI
,除非您正在处理安装外观和感觉,否则它没有按照您的想法行事(而且效率非常低) )icon
属性Timer
,允许它递增一个计数器,这样您就可以知道它被调用了多少次,并在每个刻度上更新骰子和计数器。将Timer
视为一种循环,在每次迭代(勾选)时,你需要做一些事情(比如递增计数器)
(注意 - 当看起来模具已经停止&#34;它是因为图像已经按顺序显示了一次。你可以通过将所有图像放入一个List
并使用Collections.shuffle
。这样做三次,将结果添加到另一个List
应该给你24个,没有重复的序列(好吧,它可能&#34;可能&#34;重复边界,但比使用Math.random
;))
