我正在制作Talisman Game
,到目前为止,我有方法来创建Random Characters
和WIP Main Menu
。现在,如果我从主类调用新游戏(创建角色)方法,那一切都很好,但是如果我从主菜单调用它,JFrame
变得透明并复制它们的背景(就像窗口获取时一样)陷)
新游戏方法是:
public Game(int playerNum) {
for (int i = 0; i < chars.length; i++)
chars[i] = false;
this.playerNum=playerNum;
players = new Player[playerNum];
guiChars = new Gui_Chars[playerNum];
Card.createCards();
Game.randomChar();
for (int j = 0; j < playerNum; j++)
guiChars[j].update();
}
现在,Game,randomChar()创建了字符:
public static void randomChar() {
for (int i = 0; i < playerNum; i++) {
do {
chooseChar = rnd.nextInt(14);
} while (chars[chooseChar]);
switch (chooseChar) {
case 0: {
players[i] = new Char_ASSASIN();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Assasin", players[i], "Images/assassin.jpg");
System.out.println("Player " + (i + 1) + " is an Assasin");
chars[0] = true;
break;
}
case 1: {
players[i] = new Char_DRUID();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Druid", players[i], "Images/druid.jpg");
System.out.println("Player " + (i + 1) + " is a Druid");
chars[1] = true;
break;
}
case 2: {
players[i] = new Char_DWARF();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Dwarf", players[i], "Images/dwarf.jpg");
System.out.println("Player " + (i + 1) + " is a Dwarf");
chars[2] = true;
break;
}
case 3: {
players[i] = new Char_ELF();
guiChars[i] = new Gui_Chars(
"Player " + (i + 1) + " - " + "Elf", players[i],
"Images/elf.jpg");
System.out.println("Player " + (i + 1) + " is an Elf");
chars[3] = true;
break;
}
case 4: {
players[i] = new Char_GHOUL();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Ghoul", players[i], "Images/ghoul.jpg");
System.out.println("Player " + (i + 1) + " is a Ghoul");
chars[4] = true;
break;
}
case 5: {
players[i] = new Char_MINSTREL();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Minesrel", players[i], "Images/minstrel.jpg");
System.out.println("Player " + (i + 1) + " is a Minstrel");
chars[5] = true;
break;
}
case 6: {
players[i] = new Char_MONK();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Monk", players[i], "Images/monk.jpg");
System.out.println("Player " + (i + 1) + " is a Monk");
chars[6] = true;
break;
}
case 7: {
players[i] = new Char_PRIEST();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Priest", players[i], "Images/priest.jpg");
System.out.println("Player " + (i + 1) + " is a Priest");
chars[7] = true;
break;
}
case 8: {
players[i] = new Char_PROPHETESS();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Prophetess", players[i], "Images/prophetess.jpg");
System.out.println("Player " + (i + 1) + " is a Prophetess");
chars[8] = true;
break;
}
case 9: {
players[i] = new Char_SORCERESS();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Sorceress", players[i], "Images/sorceress.jpg");
System.out.println("Player " + (i + 1) + " is a Sorceress");
chars[9] = true;
break;
}
case 10: {
players[i] = new Char_THIEF();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Thief", players[i], "Images/thief.jpg");
System.out.println("Player " + (i + 1) + " is a Thief");
chars[10] = true;
break;
}
case 11: {
players[i] = new Char_TROLL();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Troll", players[i], "Images/troll.jpg");
System.out.println("Player " + (i + 1) + " is a Troll");
chars[11] = true;
break;
}
case 12: {
players[i] = new Char_WARRIOR();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Warrior", players[i], "Images/warrior.jpg");
System.out.println("Player " + (i + 1) + " is a Warrior");
chars[12] = true;
break;
}
case 13: {
players[i] = new Char_WIZARD();
guiChars[i] = new Gui_Chars("Player " + (i + 1) + " - "
+ "Wizard", players[i], "Images/wizard.jpg");
System.out.println("Player " + (i + 1) + " is a Wizard");
chars[13] = true;
break;
}
}
}
}
字符调用GUI(从Characters
类接收信息,但那肯定不是问答):
public Gui_Chars(String character,Player player,String path) {
super(character);
setVisible(true);
setSize(430, 420);
setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);
revalidate();
}
我删除了代码中不重要的部分,没有它也发生了problam ......
最后,这是MainMenu
:
public class MainMenu extends JFrame implements ActionListener {
private static final long serialVersionUID = 1L;
JLabel num;
JButton add, sub, start;
private int i = 2;
JFrame j ;
Game game;
JLayeredPane jp1,jp2,jp3;
public MainMenu() {
j= new JFrame("Talisman");
j.setVisible(true);
j.setSize(300, 300);
j.setDefaultCloseOperation(EXIT_ON_CLOSE);
jp1 = new JLayeredPane();
jp2 = new JLayeredPane();
jp3 = new JLayeredPane();
JPanel playerNum = new JPanel(new GridBagLayout());
JPanel startPanel = new JPanel(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.insets = new Insets(30, 30, 30, 30);
add = new JButton("+1");
sub = new JButton("-1");
start = new JButton("Start");
start.setPreferredSize(new Dimension(100, 100));
num = new JLabel("" + i);
num.setFont(new Font("Serif", Font.BOLD, 40));
gbc.gridy = 0;
playerNum.add(add, gbc);
add.addActionListener(this);
add.setActionCommand("add");
gbc.gridy = 1;
playerNum.add(num, gbc);
gbc.gridy = 2;
playerNum.add(sub, gbc);
sub.addActionListener(this);
sub.setActionCommand("sub");
startPanel.add(start, gbc);
start.addActionListener(this);
start.setActionCommand("start");
jp1.add(new ContentPanel());
jp2.add(playerNum);
jp3.add(startPanel);
jp1.setLayer(new ContentPanel(), 1);
jp2.setLayer(playerNum, 2);
jp3.setLayer(startPanel, 2);
j.add(playerNum, BorderLayout.WEST);
j.add(startPanel, BorderLayout.EAST);
}
@Override
public void actionPerformed(ActionEvent e) {
String act = e.getActionCommand();
if (act.equals("start")) {
j.setVisible(false);
j.dispose();
game = new Game(i);
game.startGame();
//JFrame j = new JFrame();
//j.setVisible(true);
//j.setSize(300, 300);
}
}
}
对于长代码我很抱歉,但是我试着在调试中坐了好几个小时,找不到problam。 如果有人能帮我理解发生的事情,我将非常感激... 再次感谢,抱歉长代码...
答案 0 :(得分:0)
从查看您的代码,它告诉我您不了解Swings绘制子系统。
最重要的一点是,永远不要在Swing的事件调度事件(ETD)中进行任何长期或阻止操作。
当你在Main中调用它时它起作用的原因实际上是一个侥幸。 Java不保证哪个线程将执行Main方法。你很幸运,这不是ETD。启动Swing应用程序时,您必须始终执行以下操作
EventQueue.invokeLater(new Runnable() {
public void run() {
// Your launch code here
}
}
显然,只包含与UI相关的代码。
它现在无法正常工作的原因是,您正在动作侦听器中执行阻止代码阻止ETD更新屏幕。
for (int i = 0; i < chars.length; i++)
chars[i] = false;
.
.
.
public static void randomChar() {
for (int i = 0; i < playerNum; i++) {
do {
chooseChar = rnd.nextInt(14);
} while (chars[chooseChar]); // This is never true...
从
调用game = new Game(i);
您需要更改游戏模型,以允许从ETD之外的线程上下文中调用“randomChar”方法。我建议(为了方便),像SwingWoker(http://docs.oracle.com/javase/tutorial/uiswing/concurrency/worker.html)
从你的代码示例中,我看不出“chars [x]”在哪里设置为true ...
事实上,您可能希望阅读整个Concurrency in Swing教程......
