Java学习小记（十一）坦克大战完结篇+代码

Java360CC++C#
阅读更多

今天总算是把坦克大战做出来了不过还觉得有点不如意的地方比如说每次坦克出来的位置都是固定的，还有代码写的还是不够健壮，坦克上没有把机器人就是计算机控制的那部分给做完善，其中可能会涉及到一个人工智能的问题，本人水平有限还未尝试过还得请高手多多指教，最后还会有后续版本是图片版的这样可以美观一点。接下去要做的就是加入一些网络的特性呵呵其实要改进的地方还是真的不少的，现在把J2SE的代码如下；

Blood类主要就是那个飘来飘去的血块，吃了会涨血:

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Rectangle;


public class Blood {
    int x,y,w,h;
    TankClient tcClient;
    private boolean live=true;
    public void setLive(boolean live) {
		this.live = live;
	}
	public boolean isLive() {
		return live;
	}
	private int[][] pos={
    		{350,300},{360,300},{375,275},{400,200},{360,270},{365,290},{340,280}
		
	};
	private int step;
    public Blood(int i){
    	x=pos[0][0];
    	y=pos[0][1];
    	w=h=15;
    }
 public void Blood1(int i) {
		// TODO Auto-generated constructor stub
	}
public void draw(Graphics g){
	if(!live)return;
	 Color c=g.getColor();
	 g.setColor(Color.MAGENTA);
	 g.fillRect(x, y, w, h);
	 g.setColor(c);
	 move();
 }
 private void move(){
	 step ++;
	 if(step==pos.length){
		 step=0;
	 }
	 x=pos[step][0];
	 y=pos[step][0];
 }
 public Rectangle getRect(){
	 return new Rectangle(x,y,w,h);
 }
}

 

EXPlode;(子弹爆炸时候的火焰类)

mport java.awt.*;

public class Explode {
	int x, y;
	private boolean live = true;
	
	private TankClient tc ;
	
	int[] diameter = {4, 7, 12, 18, 26, 32, 49, 30, 14, 6};
	int step = 0;
	
	public Explode(int x, int y, TankClient tc) {
		this.x = x;
		this.y = y;
		this.tc = tc;
	}
	
	public void draw(Graphics g) {
		if(!live) {
			tc.explodes.remove(this);
			return;
		}
		
		if(step == diameter.length) {
			live = false;
			step = 0;
			return;
		}
		
		Color c = g.getColor();
		g.setColor(Color.ORANGE);
		g.fillOval(x, y, diameter[step], diameter[step]);
