是否可以创建结构的二维向量?

Is it possible to create a 2D vector of structs?

到目前为止,我已经设置了一个 2D 整数向量(下面的代码有效),但我真正想要的是一个名为 'small_tile'.

的结构的 2D 向量数组

这里我想用 txt 文件中的数据填充结构的纹理整数。稍后我还将填充其他数据值 'tile_x, tile_y, r, c'.

我希望我的问题很清楚

#include <iostream>
#include <fstream>
#include <vector>

struct smallTile
{
    int tile_x;
    int tile_y;
    int r;
    int c;
    int texture; // 0=grass, 1=sand, 2=... (get this data from txt file)
};

int main()
{
    int SMALL_TILE_VECTOR_ROWS = 5;
    int SMALL_TILE_VECTOR_COLUMNS = 6;

    //Create vector array: 5x6 containing nothing:
    std::vector<std::vector<int> > vvint(SMALL_TILE_VECTOR_ROWS, std::vector<int>(SMALL_TILE_VECTOR_COLUMNS));

    //Fill vector with file information. 
    std::ifstream file ("levelMap.txt");
    for(int r = 0; r < vvint.size(); r++)
    {
        for (int c = 0; c < vvint.at(0).size(); c++)
        {
            file >> vvint[r][c];
        }
    }
    file.close();

    //cout out the data inside the vector array so I can see it's working:
    for(int r = 0; r < vvint.size(); r++)
    {
        for(int c = 0; c < vvint.at(0).size(); c++)
        {
            std::cout<< vvint[r][c] << " ";
        }
        std::cout<< "\n";
    }

    return 0;
}
std::vector <smallTile> smalltiles;

// 问题是什么?
