如何在私有类内的2D向量中存储数据？

Question

Basically I'm getting data from a txt file and putting it into a vector in one class function, then in another class function i'm retrieving that data - but i'm getting an error message when I try to build.

In the private area of my class called 'Level' I defined a struct:

struct largeTile
{
    int texture;
}

Next in the private area of my class called 'Level' I defined a 2D vector to hold the struct objects:

vector<vector<largeTile> > vvint(int BIG_TILE_ROWS, vector<largeTile>(int BIG_TILE_COLUMNS));

Within the class that is called 'Level' I have a function that will fill the vector array with struct objects from a txt file:

for(int r = 0; r < vvint.size(); r++)
{
    for(int c = 0; c < vvint.at(0).size(); c++)
    {
        fileData >> vvint[r][c].texture;
    }
}

Though I get this build message, what am I doing wrong? I already defined the class type as 'largeTile' no?

error: '((Level*)this)->Level::vvint' does not have a class type

You've declared vvint to be a function. I guess you meant

vector<vector<largeTile>> vvint = 
    vector<vector<largeTile>>(BIG_TILE_ROWS, vector<largeTile>(BIG_TILE_COLUMNS));

to initialise it with ROWS vectors each of size COLUMNS .
