Are there any plans about implementing a lighting system into sfml? And why 'no'?

No, because SFML is a low level library (not a framework nor engine), that provides a nice API for accessing multimedia related things. With such an API you get the chance to implement a lighting system on your own on top of it, like 'Let There Be Light' proves to work. :)

After downloading latest snapshot, sf::Shader::bind(); is working. Had to rewrite some texturebindings to sf::Texture::bind(&sf::Texture); is it right, that there is no call for sf::Texture::bind(NULL); ? and when compiling, my IDE (MSVC) throws error, that he can't find the sf::Shader::bind() in the DLLs or sth.

Here the errorcode (german):

1>LightSystem.obj : error LNK2001: Nicht aufgelöstes externes Symbol ""__declspec(dllimport) public: static void __cdecl sf::Shader::bind(class sf::Shader const *)" (__imp_?bind@Shader@sf@@SAXPBV12@@Z)".
1>LightSystem.obj : error LNK2001: Nicht aufgelöstes externes Symbol ""__declspec(dllimport) public: static void __cdecl sf::Texture::bind(class sf::Texture const *,enum sf::Texture::CoordinateType)" (__imp_?bind@Texture@sf@@SAXPBV12@W4CoordinateType@12@@Z)".


Help me please :)
PS: There aren't any sfml-*.lib files in the snapshot... (so I didn't replace the old ones)

You obviously have to also build SFML... ::)
There aren't any official binaries other than the SFML 2 RC ones.

You can't just use the old .lib files. If you use the new source you either have to recompile it yourself or use the precompiled unofficial nightly builds.

Ah, yes ofcourse... :)

So, that is what I did:
-CMaked the latest snapshot and built in msvc as release (game also running release mode)
-Changed some calls to sf::Shader::bind() and sf::Texture::bind()
=> Building now properly, but the game still crashes. I can't call ls->RemoveLight(pLight) without crash, either.

What to do? Maybe some Heap Errors?


EDIT: Finally solved my problem. Turned out, that there were some mistakes managing the pointers and their assigned memory, because std::vector seems to construct its objects again after erasing single elements. I had a std::vector<Ammo> where Ammo has its own light. When erasing an Ammo they kinda get reconstructed for sorting the vector's list (closing gaps). Now i used a vector of pointers: std::vector<Ammo*> addind new Ammo with *.push_back(new Ammo()). So the vector is recreating the pointers, not my objects. (Of course I configured the destructors for deleting the objects properly).

Dat Heap :)
Thank you for the help anyway :)

Has anyone out there ever managed to get LTBL to work without convex hulls and instead with line segments? I'm just curious if this is possible as I use box2d with Chain shapes as my level terrain collision.

If you make a convex hull with only 2 points (a line segment), it should still work.
Have you heard about the new Cray super computer?  It’s so fast, it executes an infinite loop in 6 seconds.

Hello! I am trying to get started with this. I downloaded the latest release from http://sourceforge.net/projects/letthebelight/files/ and added the source folder to my include path. But when I try to write a simple code to test:

#include <SFML/System.hpp>
#include <SFML/Audio.hpp>
#include <SFML/Graphics.hpp>
#include <LTBL/Light/LightSystem.h>
#include <LTBL/Light/Light.h>
#include <LTBL/Constructs/AABB.h>
#include <iostream>
#include <assert.h>

using namespace std;

int main() {

        sf::VideoMode vidMode;
        vidMode.width = 800;
        vidMode.height = 600;
        vidMode.bitsPerPixel = 32;
        assert(vidMode.isValid());

        sf::RenderWindow mWindow(vidMode, "Prueba Light");

        // Light System
        ltbl::LightSystem ls(AABB(Vec2f(0.0f, 0.0f),
                Vec2f(static_cast<float>(vidMode.width), static_cast<float>(vidMode.height))), &mWindow,
                "lightFin.png", "lightAttenuationShader.frag");


        // Create a light
        ltbl::Light_Point* testLight = new ltbl::Light_Point();
        testLight->m_center = Vec2f(200.0f, 200.0f);
        testLight->m_radius = 500.0f;
        testLight->m_size = 30.0f;
        testLight->m_spreadAngle = 2.0f * static_cast<float>(3.14159265);
        testLight->m_softSpreadAngle = 0.0f;
        testLight->CalculateAABB();
        lightSystem.AddLight(testLight);


        while(mWindow.isOpen()){
                sf::Event mEvent;
                while (mWindow.pollEvent(mEvent)){
                        if (mEvent.type == sf::Event::Closed ||
                                ((mEvent.type == sf::Event::KeyPressed) && (mEvent.key.code == sf::Keyboard::Escape))){
                                mWindow.close();
                        }
                }
                mWindow.clear();
                mWindow.display();
        }

        return 0;
}

In the line:

ltbl::Light* testLight = new ltbl::Light();

I get the error:
The type 'ltbl::Light' must implement the inherited pure virtual method 'ltbl::Light::RenderLightSolidPortion'


I don't know if I have to compile it and add libraries like in SFML I haven't found anything, so I tried building with cmake with this git repository: https://github.com/hovatterz/light
I am on Ubuntu 12.04 so installed boost with:

sudo apt-get install libboost-all-dev

Then cmake . and then when I do make i get an error, here is what I get in the console:

ltbl::Light* testLight = new ltbl::Light();

As far as I can tell, this isn't in the code sample you posted. ltbl::Light is a base class only, and cannot be instantiated by itself. Use ltbl::Light_Point to create a point light.
Have you heard about the new Cray super computer?  It’s so fast, it executes an infinite loop in 6 seconds.

Sorry, yeah, I am getting this error using Light() as the PDF in v1.5.1 says. I changed it to use Light_Point and after adding some includes and deleting -std=c++0x flag from my compiler some errors have dissapeared but I still get this errors:

LTBL needs C++11 in order to compile. Try compiling it again with C++11 features enabled.
Have you heard about the new Cray super computer?  It’s so fast, it executes an infinite loop in 6 seconds.

You have to #include <LTBL/Light/Light_Point.h>
