System / Vector2 Problem

« on: November 30, 2009, 10:14:20 am »

Code: [Select]


//part 1
float Face(sf::Vector2<float> PosA, sf::Vector2<float> PosB)
{
    return 45.; //to be finished
}


// part 2
if (Event.Type == sf::Event::MouseMoved)
{
         sf::Vector2<float> PosMouse = sf::Vector2<float>(Event.MouseMove.X, Event.MouseMove.Y);
         Sprite.SetRotation(Face(Sprite.GetPosition, PosMouse));
}


I want to set up the function Face() to operate on two vectors and return a float, but it's giving me this error:

Main.cpp|55|error: conversion from `<unknown type>' to non-scalar type `sf::Vector2<float>' requested|

Also, I'm not sure if this belongs in Graphics, Window, or System, because I don't know which one sf:Vector2 belongs to.

EDIT: I guess it really belongs in general because it's more of a general C++ problem than it is a problem with me using SFML.

opengl32.lib

You may also need glu32.lib, if you're using any glu* function

Thanks, problem solved.

Window / Yet another unresolved external thread

Alright, I did the "Using OpenGL" tutorial, I'm using VS2005, I have sfml-window.lib added as a dependency, and I'm getting unresolved externals featuring my GL functions.

Example:

Code: [Select]

error LNK2019: unresolved external symbol __imp__glBegin@4 referenced in function _main

I didn't get any unresolved externals involving my SF functions so I think I might be missing an OpenGL library.

EDIT: I know you guys get a ton of threads like this so I'm sure this'll be fixed in a matter of seconds. I have to say that after 15 minutes of getting VS8 set up for SFML, I'm liking SFML a lot. I think I'll get into this.
