2. java貪吃蛇程序 snake = new Snake(Yard.this) 怎麼理解
new
Snake()表明是新建了一個Snake對象,()中的Yard.this是Snake創建時調用的
構造函數
里的參數。這個方法是在Yard中調用的,但是它又在Yard的
內部類
中,直接用this調用的是PaintThread,所以要加上Yard.this。因為傳入的參數應該是個對象,所以單獨用一個Yard是不行的。同時要用的Yard的實例就是現在這個,所以用的是Yard.this,將本身的這個Yard實例傳過去。
3. Java貪吃蛇的界面背景的代碼怎麼寫
這是一個最基本的界面,下面又不會的地方去查API
import java.awt.*;
import javax.swing.*;
public class View {
JFrame frame;
Container c;
JLabel backgound;
JButton start;
JLabel help;
public void first(){
frame=new JFrame("我的貪吃蛇");
c=frame.getContentPane();
c.setLayout(null);
Font f1=new Font("楷體",Font.BOLD,50);
backgound=new JLabel();
backgound.setBounds(0,0,800,600);
c.add(backgound);
backgound.setLayout(null);
start=new JButton();
start.setBounds(300,70,200,58);
start.setCursor(new Cursor(Cursor.HAND_CURSOR));
start.setBorder(null);
start.setContentAreaFilled(false);
backgound.add(start);
help = new JLabel();
help.setText("游戲幫助");
help.setBounds(180,230,500,50);
help.setForeground(Color.black);
help.setFont(f1);
backgound.add(help);
frame.setSize(800,600);
frame.setResizable(false);
frame.setVisible(true);
}
4. 用JAVA設計游戲:貪吃蛇游戲
用MVC方式實現的貪吃蛇游戲,共有4個類。運行GreedSnake運行即可。主要是觀察者模式的使用,我已經添加了很多注釋了。
1、
/*
* 程序名稱:貪食蛇
* 原作者:BigF
* 修改者:algo
* 說明:我以前也用C寫過這個程序,現在看到BigF用Java寫的這個,發現雖然作者自稱是Java的初學者,
* 但是明顯編寫程序的素養不錯,程序結構寫得很清晰,有些細微得地方也寫得很簡潔,一時興起之
* 下,我認真解讀了這個程序,發現數據和表現分開得很好,而我近日正在學習MVC設計模式,
* 因此嘗試把程序得結構改了一下,用MVC模式來實現,對源程序得改動不多。
* 我同時也為程序增加了一些自己理解得注釋,希望對大家閱讀有幫助。

7. 如何用Java語言寫一個貪吃蛇游戲
設計游戲,首先就要設計界面。首先看一下我設計的一個界面。界面分為左邊的游戲區與右邊的控制區。游戲區包含「得分信息」和貪吃蛇的游戲區,右邊控制區有「開始」「暫停」「停止」按鈕,等級選擇單選框以及游戲排行榜。
8. 用java開發的大型游戲有哪些
Java開發的大型游戲有:俄羅斯方塊、超級泡泡龍、貪吃蛇、鑽石情迷、祖瑪等。學習Java開發推薦千鋒教育,教育培訓業務分為大學生技能培訓和職後技能培訓;高校服務業務主要提供校企合作全解決方案與定製服務;企業服務業務主要為企業提供專業化綜合服務,值得信賴。
用java開發的大型游戲有以下幾個:
1、俄羅斯方塊(Tetris)
經典的益智游戲,幾乎是世界上最有影響力的益智游戲之一,游戲本身也很簡單,只要不斷消減掉落的方塊就可以了。這個游戲被模仿了很多個版本,我這里的是EA出的瘋狂俄羅斯方塊(Tetris Mania)。
2、超級泡泡龍(Super Bubble Bobble)
Taito公司開發的游戲,主角是兩只綠色和藍色的小恐龍,通過吐出泡泡來消減屏幕上的綵球,游戲本身簡單易學、妙趣橫生,女孩子玩起來會上癮的。
3、貪吃蛇(Retro Snaker)
諾基亞手機上的一個元老級游戲,這個游戲短小精悍,很具可玩性,特別適合在手機上玩。據稱,已經有超過十億人玩過這個游戲。
4、鑽石情迷(Bejeweled)
一個很好玩的益智游戲,有點像「對對碰」,游戲規則很簡單,移動相鄰的兩個鑽石,使任一排產生有三個或以上的相同鑽石,即消去,上面的鑽石靠重力落下。
5、祖瑪(Zuma)
一款休閑益智游戲,玩法很像QQ龍珠,將中間吐出來的珠子向著周圍連環滾出的同色珠子射打,夠三個就能炸裂消除,簡單有趣。
想要了解更多有關Java開發的相關信息,推薦咨詢千鋒教育。千鋒教育總部位於北京,目前已在20個城市成立分公司,現有教研講師團隊300餘人。公司目前已與國內20000餘家IT相關企業建立人才輸送合作關系,每年培養泛IT人才近2萬人,十年間累計培養超10餘萬泛IT人才,累計向互聯網輸出免費教學視頻950餘套,累積播放量超9800萬余次,實力強大,值得選擇。
9. java貪吃蛇原理
用一個數組將蛇頭的行徑記錄下來,然後第二段的下一個方格設置為蛇頭走過的方格,這樣子蛇走過的路徑都是前一段走過的,最後將跟著蛇頭走了,比如
蛇身的路徑
for(int i=snakeLength-1;i>0;i--){
rows[i]=rows[i-1];//依次將蛇前面一段走過行的路段賦值給蛇的下一段
cols[i]=cols[i-1];//依次將蛇前面一段走過列的路段賦值給蛇的下一段
}
for(int i=1;i<snakeLength;i++){
gamePanel[rows[i]][cols[i]].setBackground(Color.red);//將整個面板上蛇身走過的行和列設置為不同的顏色,當然可以用圖片來設置
}
蛇頭走過的行和列(rows[0],cols[i])要根據不同的方向加減1來將面板設置成不同的顏色
如gamePanel[rows[i]-1][cols[i]+1].setBackground(Color.red)
10. 求一段JAVA編寫的貪吃蛇小程序源代碼
用MVC方式實現的貪吃蛇游戲,共有4個類。運行GreedSnake運行即可。主要是觀察者模式的使用,我已經添加了很多注釋了。
1、
/*
* 程序名稱:貪食蛇
* 原作者:BigF
* 修改者:algo
* 說明:我以前也用C寫過這個程序,現在看到BigF用Java寫的這個,發現雖然作者自稱是Java的初學者,
* 但是明顯編寫程序的素養不錯,程序結構寫得很清晰,有些細微得地方也寫得很簡潔,一時興起之
* 下,我認真解讀了這個程序,發現數據和表現分開得很好,而我近日正在學習MVC設計模式,
* 因此嘗試把程序得結構改了一下,用MVC模式來實現,對源程序得改動不多。
* 我同時也為程序增加了一些自己理解得注釋,希望對大家閱讀有幫助。
