UI實現的難點在於Jcombobox和Jlist的選用，界面更好的跳轉，點選後組合框彈跳功能的實現，修改分辨率爲800X600
爲了實現更好的界面跳轉效果和功能選用採用了卡片佈局.
先看一下UI總共的實現類別：
Abstractpanel：對屬性進行一些基本的設置，比如顏色和字體，做爲一個ParentPanel
ConsolePanel：是玩家主要的控制面板，如小地圖和工作窗GameGUI：作爲最頂層的Frame
GamePanel：遊戲面板，也放置了一些控制方法，左右鍵的點擊，用畫筆畫了控制線
MainMenuPanel：菜單面板
MapPanel：地圖面板 注意畫框有一個像素 畫筆使用雙緩衝 使用了MouseAdapter
MutilPlayerPanel:多人遊戲界面
NetworkPanel：網絡面板
NewGamePanel：新建遊戲面板
ProgressPanel：進度條面板
SingleGamePanel：單人遊戲面板
WorkPanel：建造面板
UI的實現採用了建立父類面板的方法來節省編碼實踐，提高編碼效率。
下面闡述一下技術難點的處理方法
1.分辨率的修改
修改分辨率要用到java.awt包
使用其中的DisplayMode
調用isFullScreenSupported()方法返回的是false
new DisplayMode(1024,768,16,0);
修改顯示器的分辨率依賴於硬件，在個別顯示器中不一定好用
public void setResolution() {
GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice device=environment.getDefaultScreenDevice();
DisplayMode displayMode=new DisplayMode(1024,768,16,75);
device.setDisplayMode(displayMode);
}
public static void main(String args[]) {
FenBianLv fbl = new FenBianLv();
fbl.setResolution();
}
2.Jcombobox和Jlist的選用
JComboBox 只有一行，但是點擊右邊向下箭頭後，有一列可以選擇，至於一列可以顯示多少個列對象，可以通過setMaximumRow方法設置。
JList是直接列出很多列對象可以選擇。本身沒有滾動條，可以添加JScrollPane對象綁定Jlist到滾動條。使用setVisibleRowCount()方法調節顯示的選項數
swing默認的BasicComboBoxRenderer主要是爲了改變默認選擇每個下拉項的外觀
3.點選功能鍵後發生界面跳轉的彈跳功能實現
可以將基本組件的彈跳與QQ聊天窗口的抖動功能類比，其本質是短時間內基本組件發生了座標位置的來回變換。
public void shake() {
new Thread() {
public void run() {
for (int i = 0; i < 5; i++) {
// 獲取到的是原始位置
setLocation((int) getX(), (int) getY() - 5);
ThreadUtil.sleep(20);
setLocation((int) getX() - 5, (int) getY());
ThreadUtil.sleep(20);
setLocation((int) getX(), (int) getY() + 5);
ThreadUtil.sleep(20);
setLocation((int) getX() + 5, (int) getY());
ThreadUtil.sleep(20);
setLocation((int) getX(), (int) getY());
}
};
}.start();
}
