用c++编写一个迷宫游戏-(二)

再看一下之前的流程图，是不是编写了man.h与man.cpp后，一目了然，心中已经知道该如何写了呢？

先引入头文件并声明main函数与变量name:

#include 
#include 
#include "man.h"
#include "man.cpp"
using namespace std;
string name;
int main()
{
    return 0;
}


接着可以开始着手编写获得用户名的模块了，大家想必也对于输入输出流了如指掌了吧，在这里废话不说，直接上代码：
cout << "What's your name?" << endl;
cin >> name;

然后输入迷宫地图：
cout << "Hello," << name << ".Let's start this game!" << endl << "Target: go to the position (9,9)." << endl << "Now,write your map.(10 * 10)" << endl;
// input map
for (int i = 0 ; i < MAP_SIZE ; i++){
    cout << "The " << i << " line of map: ";
    for (int j = 0 ; j < MAP_SIZE ; j++){
 cin >> map[i][j];
    }
    cout << endl;
}

接着，在编写完class man后，创建小人就只需将类实例化。
MAN::man user(0,0,name[0]);

然后最好设定好目标，以便待会判断是否到达目的地。并声明存对象坐标的变量与接收输入的char类型变量。
POS target;
target.x = 9;
target.y = 9;
POS org;
char input;

然后编写一个while循环，作为游戏主循环。在里面获得用户输入，移动小人。
while (true)
{
    org = user.getPos();
    cout << "step: " << user.getStep() << " Position: (" << org.x << "," << org.y <<") input: ";
    cin >> input;
}

接着可以判断用户输入的指令，进行不同动作。
switch (input){
 case 'u':
     user.move(org.x,org.y - 1);
     break;
 case 'd':
     user.move(org.x,org.y + 1);
     break;
 case 'l':
     user.move(org.x - 1,org.y);
     break;
 case 'r':
     user.move(org.x + 1,org.y);
     break;
 default:
     update();
     cout << "input err!" << endl;
     break;
}

最后，可以编写一个won函数，表示胜利。
void won()
{
    char won[] = "won";
    int length = strlen(won);
    int pos = 0;
    for (int i = 0 ; i < MAP_SIZE ; i++){
 for (int j = 0 ; j < (MAP_SIZE - 1) ; j++){
     map[i][j] = won[pos];
     pos++;
     pos %= length;
 }
    }
    update();
    cout << "YOU WON!!!" << endl << "," << name << endl;
}

并判断是否达成目标
if (user.getPos().x == target.x && user.getPos().y == target.y){
    won();
    break;
}

main.cpp全部内容：
#include 
#include 
#include "man.h"
#include "man.cpp"
using namespace std;

string name;

void won();
int main()
{
    cout << "What's your name?" << endl;
    cin >> name;
    cout << "Hello," << name << ".Let's start this game!" << endl << "Target: go to the position (9,9)." << endl << "Now,write your map.(10 * 10)" << endl;
    // input map
    for (int i = 0 ; i < MAP_SIZE ; i++){
 cout << "The " << i << " line of map: ";
 for (int j = 0 ; j < MAP_SIZE ; j++){
     cin >> map[i][j];
 }
 cout << endl;
    }
    // create man
    MAN::man user(0,0,name[0]);
    // create target
    POS target;
    target.x = 9;
    target.y = 9;
    // create pos
    POS org;
    // create input
    char input;
    // main while
    while (true)
    {
 org = user.getPos();
 cout << "step: " << user.getStep() << " Position: (" << org.x << "," << org.y <<") input: ";
 cin >> input;
 switch (input){
     case 'u':
  user.move(org.x,org.y - 1);
  break;
     case 'd':
  user.move(org.x,org.y + 1);
  break;
     case 'l':
  user.move(org.x - 1,org.y);
  break;
     case 'r':
  user.move(org.x + 1,org.y);
  break;
     default:
  update();
  cout << "input err!" << endl;
  break;
 }
 if (user.getPos().x == target.x && user.getPos().y == target.y){
     won();
     break;
 }
    }
    return 0;
}
void won()
{
    char won[] = "won";
    int length = strlen(won);
    int pos = 0;
    for (int i = 0 ; i < MAP_SIZE ; i++){
 for (int j = 0 ; j < (MAP_SIZE - 1) ; j++){
     map[i][j] = won[pos];
     pos++;
     pos %= length;
 }
    }
    update();
    cout << "YOU WON!!!" << endl << "," << name << endl;
}

[完]
