我正在尝试将矢量用作成员变量。
GameOfLife.h
class GameOfLifeManager {
std::vector<Cell::Cell> cells;
...
GameOfLife.cpp
...
cells.push_back(Cell::Cell(x,y,false));
...
和Cells.h看起来像这样
#ifndef CELL_H_
#define CELL_H_
namespace Cell {
class Cell {
bool alive;
int posX;
int posY;
Cell* left;
Cell* right;
Cell* top;
Cell* bottom;
Cell* topLeft;
Cell* topRight;
Cell* bottomRight;
Cell* bottomLeft;
public:
Cell(int x, int y, bool alive);
int CountNeighbours();
void Kill();
void Resurrect();
};
} /* namespace Zell */
#endif /* CELL_H_ */
如果我试着打电话cells.push_back(Cell::Cell(x,y,false)) eclipse告诉我“从这里需要”
我也无法解密错误消息。任何想法出了什么问题？
