Title: is sfml good for me?
Post by: chrisx18 on January 17, 2010, 09:30:30 pm

i wanna make a top-down shooter with effects like... flashlight, mouse turning the player, and stuff like  when a player walks up to a window they can for example press enter.  Then a photo pops up showing whats outside.  of course all these photos would be preset and not literally 3d.

I think that SFML can be perfect for this kind of game.

If your flashlight is meant to be a true dynamic light then it may be tricky to implement, but possible.

Remember that it's always possible to write code directly in OpenGL, if SFML doesn't support a feature. Because SFML is based on OpenGL itsself, the integration is very easy.

However, this is just required in really special cases, since the SFML framework already provides ready functionality for a wide scope.

I think shaders (post-fx on SFML1.5) is a way of making these dinamic lightnings  :), I have to try it sometime.

You're following the tutorials, right? Have you put the dlls on your project's executable directory? (may be something like yourproject\bin\debug)

and my code...

Code: [Select]

#include <SFML/Window.hpp>

using namespace sf;
////////////////////////////////////////////////////////////
/// Entry point of application
///
/// \return Application exit code
///
////////////////////////////////////////////////////////////
int main()
{
    // Create the main window
    sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");

    // Start main loop
    bool Running = true;
    while (Running)
    {
        App.Display();
    }

    return EXIT_SUCCESS;
}


sorry im am completely new at this

so basically i have tried a few tutorials and instead of actually going through them I just tried compiling the source and all of them are having some type of linker error.  What am I doing wrong.

Maybe the problem is this:
1. You didn't actually read through the tutorials
2. You aren't linking the SFML libraries
