我在 java 图形编程方面很安静,但我没想到我一开始就会遇到问题:
我有这个简单的循环——它移动和调整立方体的大小,但它非常慢而且“不干净”。当您知道我的意思时,我可以看到像素在变化。我在这里能做些什么更好?为什么它这么慢?谢谢你们!
所以,这里的代码:
package game;
import javax.swing.*;
import java.awt.*;
public class Main extends JPanel implements Runnable{
Box b = new Box(0, 0, 20, 20);
Thread t = new Thread(this);
public Main(){
JFrame f = new JFrame();
f.setSize(800, 600);
f.setLocationRelativeTo(null);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLayout(null);
f.setVisible(true);
setBounds(0, 0, f.getWidth(), f.getHeight());
setBackground(Color.BLUE);
f.add(this);
t.start();
}
public void paintComponent(Graphics g){
super.paintComponent(g);
b.paint(g);
}
public void run(){
while(b.x < 100){
b.x++;
b.y++;
b.width++;
b.height++;
repaint();
try{Thread.sleep(10);}catch(Exception e){}
}
}
public static void main(String[] args) {
new Main();
}
public class Box {
public int x;
public int y;
public int width;
public int height;
public boolean used;
public Box(int x, int y, int width, int height){
this.x = x;
this.y = y;
this.width = width;
this.height = height;
}
public void paint(Graphics g){
g.setColor(Color.GREEN);
g.fillRect(x, y, width, height);
}
}
}
