Question

I have been going through the tutorials at http://www.sfml-dev.org/tutorials/1.6/ and I have ran into a problem in the using views tutorial.

Here is the section of code I am working on:

#include <SFML/Window.hpp>
#include <SFML/Graphics.hpp>

int main(){

    // Create instance of Window
    sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");

    sf::Vector2 Center(1000, 1000);
    sf::Vector2 HalfSize(400, 300);
    sf::View View1(Center, HalfSize);

    // So on...

I am using Mac OSX 10.8 and I am compiling with g++. I get the error message:

error: missing template arguments before ‘Center’

How can I correct this error?

EDIT: I somehow read the tutorial wrong. Ment to be Vector2f.

Answer 1

Your problem is exactly as the error says, you’re missing a type for the Vector2 template, and judging by constructor of the View class,

View (const sf::Vector2f &Center, const sf::Vector2f &HalfSize)

You want a Vector2<float>. These types have already been typedef‘d for you in the Vector2.hpp

// Define the most common types
typedef Vector2<int>          Vector2i;
typedef Vector2<unsigned int> Vector2u;
typedef Vector2<float>        Vector2f;
