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：
