Title: How do I represent a mathematical 2D Vector in SFML C++?
Post by: DarthBuzzKill on November 19, 2014, 06:43:36 pm

Newbie question I know, but how do I do this in SFML? Since SF::Vectors are not mathematical vectors, just placeholders for multiple parameters.

You make your own or use something like Thor.

sf::Vector2f is one possible C++ representation of a mathematical vector: it provides a variety of mathematical operations like addition or scaling. It's possible to define free functions (http://www.bromeon.ch/libraries/thor/v2.0/doc/_vector_algebra2_d_8hpp.html) to provide even more operations such as dot product.
