Title: some arithmetic operations of sf::vector missing?
Post by: Mr_Blame on June 19, 2016, 02:07:30 pm

Hi!

After some SFML usage I noticed that I can compile this:

sf::Vector2f(4, 4) + sf::Vector2f(2, 2)

but I can't compile this:

sf::Vector2f(4, 4) / sf::Vector2f(2, 2) //i get some errors here saying that operator "/" is not overloaded

The question is simple: how can I correct it or is it a feature?
 
P.S

my IDE is Visual Studio 2015

Hi,

Dividing a vector by another one doesn't make sense. That's probably why it's not implemented (as well as the multiplication of two vectors)

Oh yeah, now I see it dividing is allowed only by using scalar types!
Thanks!

You might want to look at `std::valarray` or similar, depending on what you want to do.
