Ctor to handle implicit casting between Vector2<T> typ

[Disch]

I use sf::Vector2<double> in calculations for extra precision, but pretty much everything in SFML takes sf::Vector2<float>.

It would be nice if sf::Vector2 had a ctor that could convert between different types so that these could be implicitly cast.

Such an implicit cast would be dangerous, hiding conversions that lose precision is always bad.

That's why your compiler issues a warning when you type "int x = 5.0", and you must use a static_cast

Or write a vector cast function.

Code: [Select]

template <typename Dest, typename Source>
sf::Vector2<Dest> ConvertVector(const Vector<Source>& source)
{
    return sf::Vector2<Dest>(
        static_cast<Dest>(source.x),
        static_cast<Dest>(source.y));
}

sf::Vector2<double> doubleVec;
sf::Vector2<float> floatVec = ConvertVector<float>(doubleVec)

[Disch]

Point taken.

How about an explicit ctor then?
