這篇文章主要為大家詳細(xì)介紹了C++實(shí)現(xiàn)迷宮游戲，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

迷宮游戲就是玩家在地圖中移動(dòng)，移動(dòng)至終點(diǎn)則游戲結(jié)束。

自己用文本文檔手打了個(gè)小地圖，0表示空白，1表示墻，文件名隨意，我改成了map.MapData。然后程序里定義一個(gè)全局變量char Map[MapLenX][MapLenY];(長(zhǎng)寬自定義)行為X，列為Y。定義char型常量RoadSymbol = '0', WallSymbol = '1', PlayerSymbol = '+'。

本游戲?yàn)槊嫦驅(qū)ο缶帉懙模跃鸵O(shè)計(jì)一個(gè)類。數(shù)據(jù)需要一個(gè)坐標(biāo)和一個(gè)bool型儲(chǔ)存是否到達(dá)終點(diǎn)。所以自定義了個(gè)結(jié)構(gòu)體儲(chǔ)存坐標(biāo)

struct point
{
 int x, y;
};

還需要構(gòu)造函數(shù)，析構(gòu)函數(shù)，然后寫個(gè)移動(dòng)的函數(shù)PlayerMove()，再寫個(gè)判斷是否到達(dá)終點(diǎn)的函數(shù)CheckIfWin()。每走完一步就要刷新屏幕，所以還需要寫個(gè)函數(shù)Refresh()，然后PlayerActor類就完成了。

class PlayerActor
{
public:
 point m_Location;
 bool m_IfWin;
 PlayerActor();
 ~PlayerActor();
 void PlayerMove(int _Direc);
 void Refresh(void);
 void CheckIfWin(void);
};

構(gòu)造函數(shù)析構(gòu)函數(shù)先不著急，先定義一下PlayerMove()。思路是先判斷是否可移動(dòng)。若能，當(dāng)前位置的地圖標(biāo)記設(shè)為RoadSymbol，移動(dòng)即更新坐標(biāo)，新坐標(biāo)位置在地圖上標(biāo)記為PlayerSymbol，刷新畫面，判斷輸贏。Refresh()思路為先用system("cls")清屏，然后逐行打印。若地圖上某點(diǎn)為RoadSymbol輸出空格， WallSymbol輸出'*'， PlayerSymbol輸出'+'。

接下來定義玩家起始位置和終點(diǎn)PlayerStart和PlayerEnd并初始化。main函數(shù)大體流程如下：讀入地圖，實(shí)例化PlayerActor，當(dāng)!m_IfWin時(shí)接收鍵盤按鍵來移動(dòng)，當(dāng)m_IfWIn時(shí)彈出提示框并結(jié)束。所以還需要一個(gè)全局函數(shù)PlayerControl來接收按鍵并調(diào)用PlayerMove()。

至此，構(gòu)造函數(shù)的流程也明確了。初始化m_IfWin和m_Location，在地圖上表明玩家位置和重點(diǎn)位置，刷新屏幕，沒了。然后再把能定義為常量的都定位常量，修改一下細(xì)節(jié)，就能得到一個(gè)簡(jiǎn)陋的走迷宮游戲了。
