輸入到2D矢量中的迷宮遊戲

Question

我試圖創建一個從文件中導入的迷宮，然後放入一個載有bools矢量的矢量中。

我的問題是我從文件中獲取了信息，但我不確定如何將它處理成2D矢量。在迷宮中，任何具有「+」的座標都是一條路徑，而其他任何東西（空白區等）都是一條牆。開始和結束位置是Location對象，但我還沒有編碼。

vector<vector<bool> > mazeSpec; 
string buffer; //holds lines while they are read in 
int length; //holds length of each line/# of columns 
Location start, finish; 

ifstream mazeFile("maze.txt"); 
if (!mazeFile) { 
    cerr << "Unable to open file\n"; 
    exit(1); 
} 

getline(mazeFile, buffer); // read in first line 
cout << buffer << endl; //output first line 
length = buffer.length(); //length now set so can be compared 

while (getline(mazeFile, buffer)) { 
    bool path = (buffer == "*"); 
    cout << buffer << endl; 
} 

Answer 1

你應該用char填充它。 對於文件中的每一行，添加一行mazeSpec：

mazeSpec.resize(mazeSpec.size() + 1); 

對於每一個燒焦你閱讀，添加一列以mazeSpec你的行正在努力：

mazeSpec[i].push_back(buffer[j] == '*'); 

你」我會得到這樣的東西：

int i, j; 
vector<vector<bool> > mazeSpec; 
string buffer; //holds lines while they are read in 
int length; //holds length of each line/# of columns 
Location start, finish; 

ifstream mazeFile("maze.txt"); 
if (!mazeFile) { 
    cerr << "Unable to open file\n"; 
    exit(1); 
} 

getline(mazeFile, buffer); // read in first line 
cout << buffer << endl; //output first line 
length = buffer.length(); //length now set so can be compared 

mazeSpec.resize(1); 
for(j = 0; j < buffer.length(); j++) { 
    mazeSpec[0].push_back(buffer[j] == '*'); // or perhaps '+' 
} 

i = 1; 
while (!mazeFile.eof()) { // read in maze til eof 
    getline(mazeFile, buffer); 

    mazeSpec.resize(mazeSpec.size() + 1); 
    for(j = 0; j < buffer.length(); j++) { 
     mazeSpec[i].push_back(buffer[j] == '*'); // or perhaps '+' 
    } 

    cout << buffer << endl; 
    i++; 
}
