我正在尝试制作一个简单的横向滚动游戏，我的背景颜色不起作用。它应该用fps计数器填充整个页面，但它在弹出窗口的顶部只有一小段颜色。
到目前为止，这是我的整个代码（我必须复制并粘贴，因为我“不是10级”）。
public static final int WIDTH = 640;
public static final int HIGHT = WIDTH / 4 * 3;
public static final String TITLE = "Sploocher's Epic Quest";
private static Game game = new Game();
private boolean running = false;
private Thread thread;
public void init(){
}
public void tick(){
}
public void renderBackground(Graphics g){
}
public void renderForeground(Graphics g){
}
public void render(){
BufferStrategy bs = this.getBufferStrategy();
if(bs == null) {
createBufferStrategy(3);
return;
}
Graphics g = bs.getDrawGraphics();
g.setColor(Color.BLACK);
g.fillRect(0,0,WIDTH,HEIGHT);
//////////////////////////////////////////////////
renderBackground(g);
renderForeground(g);
g.dispose();
bs.show();
}
@Override
public void run() {
init();
long lastTime= System.nanoTime();
final double numTicks = 60.0;
double n = 1000000000 / numTicks;
double delta = 0;
int frames = 0;
int ticks = 0;
long timer = System.currentTimeMillis();
while(running){
long currentTime = System.nanoTime();
delta += (currentTime - lastTime) / n;
lastTime = currentTime;
if(delta >= 1){
tick();
ticks++;
delta--;
}
render();
frames++;
if(System.currentTimeMillis() - timer > 1000){
timer+=1000;
System.out.println(ticks + "Ticks, FPS: " + frames);
ticks = 0;
frames = 0;
}
}
stop();
}
public static void main(String args[]){
JFrame frame = new JFrame(TITLE);
frame.add(game);
frame.setSize(WIDTH, HIGHT);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setFocusable(true);
frame.setLocationRelativeTo(null);
frame.setResizable(false);
frame.setVisible(true);
frame.pack();
game.start();
}
private synchronized void start(){
if(running)
return;
else
running = true;
thread = new Thread(this);
thread.start();
}
private synchronized void stop(){
if(!running)
return;
else
running = false;
try {
thread.join();
} catch (InterruptedException e){
e.printStackTrace();
}
System.exit(1);
}
}
如果有人能帮我弄清楚如何修复我的代码，我真的很感激。
