我有一个小行星类:
class Asteroid
{
public:
Asteroid();
float GetMovementSpeed();
float GetRotationSpeed();
Placement^ GetCurrentOrientation();
void UpdateOrientation( Placement^ placement );
float GetPosX();
float GetPosY();
float GetPosZ();
float GetRotX();
float GetRotY();
float GetRotZ();
private:
float movementSpeed;
float rotationSpeed;
Placement^ placement;
//float x;
//float y;
//float z;
//float rotX;
//float rotY;
//float rotZ;
};
我已经建立了以下 vector ,并用小行星填充了它:) ...
vector<Asteroid*> asteroids;
asteroids.push_back( new Asteroid() );
asteroids.push_back( new Asteroid() );
asteroids.push_back( new Asteroid() );
for(std::vector<Asteroid*>::iterator asteroid = asteroids.begin(); asteroid != asteroids.end(); ++asteroid)
{
asteroid-> //Can't access the methods of the asteroid class?
}
但是在迭代器内部,小行星无法访问小行星类的方法。我错过了什么?
最佳答案
迭代器的行为就像一个指针。您的类型也是指针。您要做的是首先“取消引用”迭代器,然后使用指针:
(*asteroid)->doSomething();
