我一直在尝试解决,但它永远不会改变屏幕。我试图使用在render()
方法中看到的图形。告诉我,如果渲染方法内部出现问题,我可以放松一下,因为我似乎无法找到问题所在。为什么屏幕不会变色?
import java.awt.Canvas;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.*;
import javax.swing.JFrame;
public class Game extends Canvas implements Runnable {
private static final long serialVersionUID = 1L;
public static int width = 300;
public static int height = width/16*9;
public static int scale = 3;
private Thread thread;
private boolean running = false;
private JFrame frame;
public synchronized void start() {
thread = new Thread();
thread.start();
running = true;
}
public synchronized void stop() {
running = false;
try{
thread.join();
}catch(InterruptedException e) {
e.printStackTrace();
}
}
public Game() {
Dimension size = new Dimension(width * scale, height * scale);
setPreferredSize(size);
frame = new JFrame();
}
public void run() {
while(running) {
tick();
render();
}
}
void tick() {}
public void render() {
BufferStrategy bs = getBufferStrategy();
if(bs==null){
createBufferStrategy(3);
return;
}
Graphics g = bs.getDrawGraphics();
g.setColor(Color.BLACK);
g.fillRect(0, 0, getWidth(), getHeight());
bs.dispose();
bs.show();
}
public static void main(String[] args) {
Game game = new Game();
game.frame.setResizable(false);
game.frame.setTitle("Rain");
game.frame.add(game);
game.frame.pack();
game.frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
game.frame.setLocationRelativeTo(null);
game.frame.setVisible(true);
game.start();
}
}
您在展示()之前将BufferStrategy放置()。那不好。 –
我试过了。似乎没有工作。 – user2469009
您的代码看起来与[此问题]非常相似(http://stackoverflow.com/questions/20547542/bufferstrategy-not-working/20547780#20547780)。我会尝试比较你的代码,因为我认为他们可能使用相同的教程。 – DoubleDouble
