我想在鼠标 x 和 y 处绘制一个矩形。我希望有很多矩形,所以如果我要单击 JFrame 上的 50 ,50 坐标,它将绘制一个矩形,然后如果我单击其他地方,它将在那里绘制另一个矩形,但不会删除另一个矩形,所以我本来可以点击 5 次(<--example)然后我会同时拥有五个矩形。
矩形也应该具有固定的高度和宽度,因此当您单击特定区域时,它将绘制一个 10 x 10 的矩形,它会记住所有其他已绘制的矩形并将它们绘制在同一个位置,并且我如何将它绘制为数组列表(如果有的话)
我的代码:
公共类 Game 扩展 Canvas 实现 Runnable { private static final long serialVersionUID = 1L;
public boolean running = false;
public static final String title = "tilebased game!";
private Thread thread;
public int height = 600;
public int width = 800;
private Dimension d = new Dimension(width, height);
public static Rectangle block;
public static Rectangle[] blocks = new Rectangle[2];
public static int blocknum = 0;
public static int xCreate;
public static int yCreate;
public static int xcoord;
public static int ycoord;
public static ArrayList<Rectangle> rects = new ArrayList<Rectangle>();
public static boolean islicked = false;
public Game() {
setPreferredSize(d);
setMinimumSize(d);
setMaximumSize(d);
addMouseListener(new tile());
addMouseMotionListener(new tile());
}
public void start() {
running = true;
new Thread(this).start();
}
public void stop() {
running = false;
}
public static void main(String[] args) {
Game g = new Game();
JFrame f = new JFrame();
f.add(g);
f.pack();
f.setTitle(title);
f.setResizable(false);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLocationRelativeTo(null);
f.setVisible(true);
g.start();
}
public void run() {
while(running){
tick();
render();
}
try{
Thread.sleep(5);
}catch(Exception e){
}
}
public void render() {
BufferStrategy bs = getBufferStrategy();
if (bs == null) {
createBufferStrategy(2);
return;
}
Graphics g = bs.getDrawGraphics();
g.setColor(Color.white);
for (int i = 0; i < rects.size(); i++) {
Rectangle rect = rects.get(i);
}
g.dispose();
bs.show();
}
public void tick() {
}
}
和其他班级。
