Java Agario 单机

Question

如何制作 agario 的 java 单人游戏版本？我想使用面向对象编程。所以应该有 Dot、Blob 和一个 Controller Object。(我只是想分享我的代码，所以不要投反对票:)

Answer 1

我是这样做的。有随机颜色的点，从 20 大小开始的 Blob 。线程每几毫秒检查一次冲突。

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);
    }
}

Blob :

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);
    }
}

Controller :

package agario;

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Frame;
import java.awt.Graphics;
import java.awt.Label;
import java.awt.Rectangle;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.Random;

public class Controller {
    ArrayList<Blob> blobs = new ArrayList<Blob>();
    public ArrayList<Dot> dots = new ArrayList<Dot>();
    Blob b = new Blob(50,50,10,Color.CYAN);
    MyFrame mf = new MyFrame("Agario");
    Label l = new Label("10");
    int mouseX = 0;
    int mouseY = 0;
    static int score = 30;
    static int xDis = 0;
    static int yDis = 0;
    public static void main(String[] args){
        new Controller().startGame();
    }
    public void startGame(){
        mf.addMouseMotionListener(new MyMouseMoveListener());
        mf.add(l,BorderLayout.NORTH);
        Refresh rf = new Refresh();
        Thread t = new Thread(rf);
        t.start();

        while(true){
            try{
                Random r = new Random();
                Thread.sleep(r.nextInt(40));

                double dis = Math.sqrt(xDis*xDis + yDis*yDis);
                double easingAmount = 20;
                b.x += xDis / easingAmount;
                b.y += yDis / easingAmount;


                if(r.nextInt(10) == 5){
                    int randX = r.nextInt(600);
                    int randY = r.nextInt(600);
                    Dot d = new Dot(randX,randY);
                    synchronized(dots){
                        dots.add(d);
                    }
                    mf.add(d);
                    mf.repaint();
                }
            }catch(Exception e){

            }
        }
    }
    class Refresh implements Runnable{

        public void run() {
            while(true){
                Random ran = new Random();
                try{
                    Thread.sleep(ran.nextInt(20));

                            i.remove();
                            b.size += 1;
                            l.setText(String.valueOf(Integer.parseInt(l.getText())+1));
                            score += 1;
                        }
