I am very sorry to pasted a very lengthy code here, but I found that's the best way to present this question. I think my compiler is ignoring the #include "Vector2.hpp". so please help me to solve this error. Your response would be very apricated!! thank you
getting error in this part of code (function name : liftpiece) :
if(e.key.code==Mouse::Left)
{
ismove=false;
Vector2f p = s2[n].getPosition() + Vector2f(53.25,53.25);
Vector2f newPos = Vector2f( 106.5*int(p.x/106.5), 106.5*int(p.y/106.5) );
s2[n].setPosition(newPos);
}

/// \class sf::Vector2
/// \ingroup system
///
/// sf::Vector2 is a simple class that defines a mathematical
/// vector with two coordinates (x and y). It can be used to
/// represent anything that has two dimensions: a size, a point,
/// a velocity, etc.
///
/// The template parameter T is the type of the coordinates. It
/// can be any type that supports arithmetic operations (+, -, /, *)
/// and comparisons (==, !=), for example int or float.
///
/// You generally don't have to care about the templated form (sf::Vector2<T>),
/// the most common specializations have special typedefs:
/// \li sf::Vector2<float> is sf::Vector2f
/// \li sf::Vector2<int> is sf::Vector2i
/// \li sf::Vector2<unsigned int> is sf::Vector2u
///
/// The sf::Vector2 class has a small and simple interface, its x and y members
/// can be accessed directly (there are no accessors like setX(), getX()) and it
/// contains no mathematical function like dot product, cross product, length, etc.
///
/// Usage example:
/// \code
/// sf::Vector2f v1(16.5f, 24.f);
/// v1.x = 18.2f;
/// float y = v1.y;
///
/// sf::Vector2f v2 = v1 * 5.f;
/// sf::Vector2f v3;
/// v3 = v1 + v2;
///
/// bool different = (v2 != v3);
/// \endcode
///
/// Note: for 3-dimensional vectors, see sf::Vector3.
