Java Agario单机

Question

如何制作java单播放器版本的agario？我想使用面向对象的编程。所以应该有Dot，Blob和Controller对象。(我只想分享我的代码，所以不要投反对票:)

Answer 1

我是这样做的。有随机颜色的圆点，从20个大小开始。线程每隔几毫秒检查一次碰撞。

点：

package agario;

import java.awt.Color;
import java.awt.Component;
import java.awt.Graphics;
import java.util.Random;

public class Dot extends Component{
    public int x;
    public int y;
    public Color c;
    public int size;
    Dot(int x, int y){
        this.x = x;
        this.y = y;
        Random rand = new Random();
        int r = rand.nextInt(255);
        int green = rand.nextInt(255);
        int b = rand.nextInt(255);
        this.c = new Color(r,green,b);
        this.size = rand.nextInt(50);
    }
    public void paint(Graphics g){
        g.setColor(c);
        g.fillOval(this.x, this.y, this.size, this.size);
    }
}

布洛布：

package agario;

import java.awt.Color;
import java.awt.Component;
import java.awt.Graphics;

public class Blob extends Component{
    public int x;
    public int y;
    public int size;
    public Color color;
    public static Blob blob = new Blob(800,100,40,Color.blue);
    Blob(int x, int y, int size, Color c){
        this.x = x;
        this.y = y;
        this.size = size;
        this.color = c;
    }
    public void paint(Graphics g){

        g.setColor(color);
        g.fillOval(x, y, size, size);
    }
}
