实现全屏

游戏一般都是全屏显示的，那我们如何使用java实现一个全屏窗体呢？本节我们就来教大家这个技巧。

新增一个managers包，包里新建一个ScreenManager.java类，代码如下：
主要代码就一行：device.setFullScreenWindow(mainFrame);

package managers;

import config.Config;

import java.awt.*;


public class ScreenManager {
	
	public static GraphicsDevice device = null;
	
	private DisplayMode[] _bestDisplayModes = new DisplayMode[] {
		new DisplayMode(640, 480, 32, 0),
		new DisplayMode(640, 480, 16, 0)
	};
	

	public ScreenManager(Frame mainFrame){
		 GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
		 device = env.getDefaultScreenDevice();
	     device.setFullScreenWindow(mainFrame);
	     if(device.isDisplayChangeSupported()){
	    	 _chooseBestDisplayMode(device);
	     }
	     mainFrame.createBufferStrategy(Config.BUFFERS);

	}
	

	private DisplayMode _getBestDisplayMode(GraphicsDevice device){
		for(int x = 0; x < _bestDisplayModes.length; x++){
			DisplayMode[] modes = device.getDisplayModes();
			for(int i = 0; i < modes.length; i++){
				if(modes[i].getWidth() == _bestDisplayModes[x].getWidth() &&
				modes[i].getHeight() == _bestDisplayModes[x].getHeight() &&
				modes[i].getBitDepth() == _bestDisplayModes[x].getBitDepth()){
					return _bestDisplayModes[x];
				}
			}
		}
		return null;
	}
	

	private void _chooseBestDisplayMode(GraphicsDevice device){
		DisplayMode bestMode = _getBestDisplayMode(device);
		if (bestMode!=null){
			device.setDisplayMode(bestMode);
		}else{
			System.out.println("ERROR!");
		}
	}

	
}

GameApp.java 修改如下：
