前言

之前學(xué)完java基礎(chǔ)課程，試著簡(jiǎn)單做了一下java的一個(gè)五子棋小游戲，記錄下來(lái)。

界面

由于直接用的java庫(kù)中的一些基本控件寫的一個(gè)GUI，并沒(méi)有做過(guò)多優(yōu)化，感覺(jué)比較丑下面是界面展示：

黑子先行，但是我這邊簡(jiǎn)化規(guī)則，并沒(méi)有考慮黑子先行的一些禁手。

下面直接貼代碼

接口類

我把五子棋界面的一些常量都定義在了這個(gè)接口類中，包括棋盤的起始坐標(biāo)，棋盤線的間距和棋子半徑

public interface constant { int[][] chessLocation = new int[15][15]; static final int x = 50; //左上角位置 static final int y = 50; static final int LN = 15; //棋盤一些常量 static final int R = 45;}實(shí)現(xiàn)類

接口

這個(gè)類中繼承了 constant、MouseListener、ActionListener三個(gè)接口

其中：

constant為自己定義 MouseListener為鼠標(biāo)監(jiān)聽(tīng) ActionListener為事件監(jiān)聽(tīng)

函數(shù)

show()繪制窗口基本框架paint()繪制棋盤網(wǎng)格線和棋子IsWin()判斷輸贏的基本邏輯mouseClicked()獲取鼠標(biāo)位置，判斷棋子落點(diǎn)等actionPerformed()判斷鼠標(biāo)點(diǎn)擊哪個(gè)按鈕（開(kāi)始游戲or認(rèn)輸or悔棋）執(zhí)行相應(yīng)操作

其中比較有趣的是五子棋判贏方式，假設(shè)棋盤大小15*15，則我只需要判斷正中間的13*13d的格子，向兩邊擴(kuò)展，判斷是否五子連珠。

具體說(shuō)明代碼里都有注釋，不多贅述。

主函數(shù)類

public class Main_game { public static void main(String[] args) {game_logic start=new game_logic();start.ShowUI(); }}總結(jié)

實(shí)現(xiàn)了五子棋小游戲的基本功能，但是略感粗糙，細(xì)節(jié)不足。對(duì)于基本控件調(diào)用一學(xué)就會(huì)，做一個(gè)小的游戲demo這是對(duì)流程控制和操作邏輯的訓(xùn)練很有效的一種方式。之前看了別人的代碼覺(jué)得簡(jiǎn)單，但是自己寫的時(shí)候往往邏輯流程難以連續(xù)，思維混亂，有些過(guò)程只有自己寫了才知道其中的坑。

以上就是本文的全部?jī)?nèi)容，希望對(duì)大家的學(xué)習(xí)有所幫助，也希望大家多多支持好吧啦網(wǎng)。
