貪吃蛇小游戲原始碼分享

創建2個檔案夾，一個是放原始碼還有一個檔案夾是發圖片的，

package com.Bubbles.snake;

import javax.swing.*;
import java.net.URL;

public class Data {
//存放外部資料

//1.頭部的圖片 URL ：定位圖片的地址 ImageIcon：圖片
public static URL headerURL = Data.class.getResource ("/statics/header.png");
public static ImageIcon header = new ImageIcon (headerURL);

//2.頭部
public static URL upUrl = Data.class.getResource ("/statics/up.png");
public static URL downUrl = Data.class.getResource ("/statics/down.png");
public static URL leftUrl = Data.class.getResource ("/statics/left.png");
public static URL rightUrl = Data.class.getResource ("/statics/right.png");
public static ImageIcon up = new ImageIcon (upUrl);
public static ImageIcon down = new ImageIcon (downUrl);
public static ImageIcon left = new ImageIcon(leftUrl);
public static ImageIcon right = new ImageIcon (rightUrl);
//3.身體
public static URL bodyUrl = Data.class.getResource ("/statics/body.png");
public static ImageIcon body = new ImageIcon (bodyUrl);
//4.食物
public static URL foduUrl = Data.class.getResource ("/statics/food.png");
public static ImageIcon food = new ImageIcon (foduUrl);

import java.util.Random;

//1.繼承JPanel，才能實作面板效果
public class GamePamel extends JPanel implements KeyListener, ActionListener {
//7.畫蛇
int lenth; //蛇的長度
int [] snakex = new int[600]; //蛇的坐標x
int [] snakeY = new int[500]; //蛇的坐標Y
String fx ; //12.蛇的方向，R ：右，L：左 U: 上 D:下

boolean isStrart = false; //游戲是否開始

//定義變數
Timer timer = new Timer (100,this);//定時器
//定義一個食物
int foodx;
int foody;
Random random = new Random ();
//死亡判斷
boolean isFall = false;
//積分系統
int score;
//10.構造器
public GamePamel(){
init ();
//14.獲取鍵盤的監聽事件
this.setFocusable (true);
this.addKeyListener (this);
timer.start ();//讓時間動起來
}

//8.初始化
public void init(){
lenth = 3;
snakex[0] = 100; snakeY[0] = 100; //頭部坐標
snakex[1] = 75; snakeY[1] = 100; //第一個身體坐標

foody = 75 + 25 * random.nextInt (24);
score = 0;
}

//2.畫板：畫界面，畫蛇
//3.重寫方法paintComponent
@Override
protected void paintComponent(Graphics g) { //Graphics =畫筆
super.paintComponent (g); //清屏
this.setBackground (Color.BLACK); //4.設定背景的顏色
//5.繪制頭部的公告欄
Data.header.paintIcon (this,g,25,11); //距離
g.fillRect (25,75,850,600); //6.繪制游戲區域

//9.畫一條靜態的小蛇
if(fx.equals ("R")){ //右走
Data.right.paintIcon (this,g,snakex[0],snakeY[0]); //腦袋
} else if (fx.equals ("L")){ //左走
Data.left.paintIcon (this,g,snakex[0],snakeY[0]); //腦袋
} else if (fx.equals ("U")){ //上走
Data.up.paintIcon (this,g,snakex[0],snakeY[0]); //腦袋
} else if (fx.equals ("D")){ //下走
Data.down.paintIcon (this,g,snakex[0],snakeY[0]); //腦袋
}
//11.一個一個寫的身體比較麻煩，所以要將他回圈
for (int i = 1; i < lenth; i++) {
Data.body.paintIcon (this,g,snakex[i],snakeY[i]); //蛇的身體長度通過lenth來控制
}
//畫積分
g.setColor (Color.white);
g.setFont (new Font ("微軟雅黑",Font.BOLD,18));

//兩一個文字，String
g.setColor (Color.WHITE);//設定畫筆的顏色

g.setFont (new Font ("微軟雅黑",Font.BOLD,40)); //設定字體
g.drawString ("游戲失敗,按下空格重新開始",200,300);
}

}

//13.接收鍵盤的輸入：監聽
@Override

//鍵盤按下，未釋放
//獲取按下的鍵盤是哪個鍵
int KeyCode = e.getKeyCode ();
//判斷
if (KeyCode==KeyEvent.VK_SPACE){ //如果按下的是空格鍵

repaint ();//重繪界面
}
//鍵盤控制走向

fx="R";

fx="U";
}else if (KeyCode==KeyEvent.VK_DOWN){
fx="D";
}
}

@Override
public void actionPerformed(ActionEvent e) {
//如果游戲處于開始狀態，并且游戲沒有結束
if(isStrart && isFall==false ){
//右移
for (int i = lenth-1; i >0 ; i--) {//除了腦袋，身體都向前移動
snakex[i] =snakex[i-1];
snakeY[i] =snakeY[i-1];
}
//通過控制方向讓頭部移動
if(fx.equals ("R")){
snakex[0]= snakex[0] + 25; //頭部移動
if(snakex[0]>850){ snakex[0] = 25; }
}else if (fx.equals ("L")){

}else if (fx.equals ("D")){
snakeY[0] =snakeY[0] + 25; //頭部移動
if(snakeY[0]>650){ snakeY[0] = 75; }
}
//如果小蛇的頭和咋們的食物重合了
if(snakex[0]==foodx && snakeY[0]==foody){
//長度+1
lenth++;

score = score +10;

//重新生成食物
foodx = 25 + 25 * random.nextInt (34);
foody = 75 + 25 * random.nextInt (24);

}
//結束判斷
for (int i = 1; i <lenth ; i++) {
