我搞砸了我的继承权
||
因此，我有一个Piece类，它应该表示板上的棋子，我计划从中继承其他两个类。但是，这样做有很多问题；这是到目前为止的相关代码。
///
/// PIECE CLASS HERE
/// this is an abstract class from which Barrier and Pawn inherit.
class Piece
{
public:
Piece(Space* start);
sf::Shape m_Circle;
protected:
int m_X;
int m_Y;
int m_radius;
Space* CurrentSpace;
};
Piece::Piece(Space* start):
m_X(start->GetX()),
m_Y(start->GetY()),
m_radius(14),
CurrentSpace(start)
{}
///
/// BARRIER CLASS HERE
/// these are the white stones that block a player\'s path
class Barrier : public Piece
{
public:
Barrier(Space* initial);
void Move(Space* target, bool isCapturing);
};
Barrier::Barrier(Space* initial)
{
Piece(initial);
m_Circle = sf::Shape::Circle((float)m_X, (float)m_Y, (float)m_radius, sf::Color(255, 255, 255));
Move(initial);
}
void Barrier::Move(Space* target, bool isCapturing)
{
int xChange = abs(target->GetX() - m_X);
int yChange = abs(target->GetY() - m_Y);
m_Circle.Move((float)xChange, (float)yChange);
CurrentSpace.ToggleOccupied();
if(!isCapturing)
{
(*target).ToggleOccupied();
}
CurrentSpace = target;
}
no matching function for call to Piece::Piece()
declaration of \'Piece initial\' shadows a parameter
no matching function for call to \'Barrier::Move(Piece&)\'
request for member \'ToggleOccupied\' in \'((Barrier*)this)->Barrier::<anonymous>.Piece::CurrentSpace\', which is of non-class type \'Space*\'|

讹巳漓把备
Barrier::Barrier(Space* initial) { Piece(initial); m_Circle = sf::Shape::Circle((float)m_X, (float)m_Y, (float)m_radius, sf::Color(255, 255, 255)); Move(initial); }Barrier::Barrier(Space* initial) : Piece(initial) { m_Circle = sf::Shape::Circle((float)m_X, (float)m_Y, (float)m_radius, sf::Color(255, 255, 255)); Move(initial); }森含械
被编译器忽略。您正在声明一个与参数同名的变量：要使用初始化基础对象，必须使用成员初始化程序列表：同样，“ 9”函数需要两个参数，但是您只传递了一个。您忘记了布尔值。疾很毋悲
是由于您已将CurrentSpace声明为指针，因此应为 CurrentSpace-> ToggleOccupied（）;为陡土
Barrier(Space* initial): Piece(initial) { ... }Barrier(Space* initial): Piece() { ... }
