Graphics / Indexed vertex arrays

« on: May 20, 2013, 08:02:31 pm »

I've read about SFML's support for vertex arrays.
Is there any support for rendering indexed vertex arrays, where I'd have an array of vertices and an array of index numbers, beyond using raw OpenGL?

You were right. There was an old SFML install in my /usr/local/ directory, and deleting it got rid of my compile error. Thanks.

General / Xcode project doesn't link to SFML framework if 'Header Search Path' is set

« on: May 19, 2013, 02:21:16 am »

I have an Xcode project, using Xcode v3.2.6 on Mac OS X 10.6.8.
I've added the SFML 2.0 frameworks to it - SFML.framework and all of the sfml-<subsystem>.frameworks, located in /Library/Frameworks. This compiles fine.

However, I also need to include a static library, the headers in /usr/local/include and the .a files in /usr/local/lib.
My understanding of Xcode is, in order to use headers and libraries kept in /usr/local, I have to go to my project settings and add /usr/local/include to my Header Search Paths.

The problem is when I do that, my project is unable to link to the SFML framework(s).

This is the entirety of my code:

// main.cpp
#include "SFML/Graphics.hpp"

int main (int argc, char * const argv[])
{
        sf::RenderWindow window(sf::VideoMode(800, 600), "My window");
        return 0;
}

I get a "Symbol(s) not found) error where I try to initialize the window.
Strangely enough, the linker error goes away when I take out the constructor so that it just reads sf::RenderWindow window;.

Graphics / Best practice for drawing multiple sprites with same image/texture

« on: July 23, 2012, 02:39:06 am »

Suppose I want to draw an image twice.  It could be for two entities with different positions but the same image, or it could be for tiles in a tilemap.

Is it better to have a sprite for each instance of the image I want to draw?  Or can I get away with having only a single sprite for the image, where I'd change the sprite's position whenever I want to draw its image?
