Java Game Development(27) - Handling Key Events

import java.awt.*;

import java.awt.event.*;

public class KeyTest extends Core implements KeyListener { → 是從鍵盤的監聽器

public static void main(String[] args) {

new KeyTest().run();

}

private String mess = "";

//init also call init from super class

public void init() {

super.init(); → 調用init()(core java)

Window w = s.getFullScreenWindow();

w.setFocusTraversalKeysEnabled(false); → 鍵盤設置普通按鈕

w.addKeyListener(this); → 等待鍵盤輸入

mess = "Press escape to exit";

}

//按下的鍵

public void keyPressed(KeyEvent e) { → 當有人按鍵調用此方法

int keyCode = e.getKeyCode();

if (keyCode == KeyEvent.VK_ESCAPE) { → 當按下ESC

stop(); → 調用stop()方法(in Core.java)

} else {

mess = "Pressed: " + KeyEvent.getKeyText(keyCode); → 按哪個鍵

e.consume(); → 等待一些鍵入組合(例子:ALT + F2)

}

}
