因此,在完成一本介绍性书籍后,我正在试着用一些C++语言,而且我陷入了困境。我制作了一个对象向量,每个对象都有一个SFML圆对象作为成员,并且我希望main()去绘制这些圆。该矢量称为theBoard
,但是当我试图访问它,我得到以下错误信息:成员未在范围内声明?
error: request for member 'theBoard' in 'GameBoard', which is of non-class type 'Board*'
error: 'theBoard' was not declared in this scope
我是新来这个(就从这两年的Python),所以我相信我做了某处出现错误。下面是主板创造的相关代码:)
class Board
{
public:
//These are the member functions.
Board();
~Board();
vector<Space*> CreateBoard();
//This will be the game board.
vector<Space*> theBoard;
//These clusters represent the waiting areas for pieces not yet in the game.
vector<Space*> Cluster1;
vector<Space*> Cluster2;
vector<Space*> Cluster3;
private:
//These integers represent the number of spaces on each row, starting at the top (which is row [0])
vector<int> RowNums;
};
Board::Board()
{
//Fill in RowNums with the right values.
RowNums.push_back(1);
RowNums.push_back(17);
RowNums.push_back(2);
RowNums.push_back(17);
RowNums.push_back(1);
RowNums.push_back(1);
RowNums.push_back(5);
RowNums.push_back(2);
RowNums.push_back(7);
RowNums.push_back(2);
RowNums.push_back(11);
RowNums.push_back(3);
RowNums.push_back(17);
RowNums.push_back(4);
RowNums.push_back(17);
//Then, create the board.
theBoard = CreateBoard();
}
CreateBoard(是返回指针空间物体的向量一个很长很长的功能。我怀疑这里存在问题,因为当我尝试访问main()中的Space对象的圈子成员时,我收到唯一的错误消息。在我看来,好像我已在相关范围内宣布theBoard
,即作为理事会类别的数据成员。
我的main()函数,在情况下,它是很重要的:
int main()
{
//This sets up the display window.
sf::RenderWindow App(sf::VideoMode(1200, 900, 32), "Malefiz");
//This creates the board on the heap, and a pointer to it.
Board* GameBoard = new Board();
cout << "Board made.";
//This is the game loop.
while(App.IsOpened())
{
//This is used to poll events.
sf::Event Event;
while(App.GetEvent(Event))
{
//This closes the window.
if(Event.Type == sf::Event::Closed)
{
App.Close();
}
}
//This gets the time since the last frame.
//float ElapsedTime = App.GetFrameTime();
//This fills the window with black.
App.Clear(sf::Color(200, 200, 125));
//This draws the places into the window.
for(int i = 0; i < GameBoard.theBoard.size(); ++i)
{
App.Draw(GameBoard.*theBoard[i].m_Circle);
}
//This displays the window.
App.Display();
}
return EXIT_SUCCESS;
}
哦,可爱的系统匈牙利符号......(我讨厌它!):)我明白'p'的前缀,但从那里请:不。 – 2011-06-13 18:17:01
@David:是的,这是我的匈牙利用法的限制。我认为'p'很重要,因为指针对所需的基本语法有如此巨大的影响。我同意所有'lpsz'微软的东西都是疯了! – 2011-06-13 19:21:15
