I’m used to WinForms graphics, but I’ve been dabbling in XNA, and one thing I’ve noticed is that the Point object isn’t very useful, and doesn’t seem to be used very much. For positioning, the various SpriteBatch Draw methods use either a Rectangle or a Vector2. And Vector2 has a lot of useful static and instance methods, whereas Point has basically nothing except the X and Y properties.
Why does XNA use a Vector2 to represent position instead of a Point? I realize they both have an X and a Y, but semantically and logically, using a Vector2 instead of a Point to represent location makes no sense to me. (For instance, if you normalize the Vector2, suddenly you have a different location!)
Is this as strange as it seems, or am I missing something?
Even assuming
Pointwere using float values, what meaning would you give to “adding 2 points together”? Now adding vectors to update positions is a well understood and widely used concept, so vectors map better to describing positions and speeds in a virtual world.
