SFBL (SFML Box2D Light)

[Mj PsykOo]

SFML Box2D Light is a very simple library and easy-to-use, this library allows you to add cool lighting effects including shadow casting etc...
here are some pictures:



Current Features:
- Spotlight
- Conelight

The screenshots look pretty :-) good job.

I've noticed your repo has no license information; you might want to add some so that users know how they can use your library commercially and non-commercially.

Split the GPL Discussion to keep this thread focused on SFBL instead.

I really don't care about licenses if it was a license that says "do whatever you want with this library" then I would choose it.
if the GPL licence will coz problems then the next versions of library will be released under another license.
so could you advice me with a licence that allows you to use it as you want ?
and Thanks,

The zlib/png license that SFML uses (full text here: https://github.com/SFML/SFML/blob/master/license.txt) is my personal favorite. It's super-short, non-lawyers can read it, and it basically just says "don't lie about who wrote this software", which should not be a problem for anybody.

Though I've always been tempted to try the WTFPL...

[Mj PsykOo]

so can i just change the license of current version of library ??

[Ixrec]

It's your project.  Changing the license is entirely up to you.

[Mj PsykOo]

ok the license has been changed to zlib/png license. same as SFML license.

Screenshots look really nice. Good work

This is cool. Very inspiring. I am planning to develop one as well. I will be checking on this project from time to time. Thanks for sharing!

MinGW 4.9.2 static binaries have been already generated

Nice of you to put this out for others to use.  I downloaded the source from github, but ran into a problem.  You include MinGW lib binaries and I'm unsure of the build system.  Trying to get it compiled on linux I have an issue.  Make doesn't recognise the makefile for one.  Another is that there is some hangup with Box2D(uses premake4 build system).  Premake4.3 has a bug in it that premake4.4 fixes, but it's in beta still and I was having difficulty still in compiling it's git version so I can then compile Box2D to then compile your library.....

I think you see where I'm going with this.  Any ability on your end to provide a linux version of the lib binaries, or should I keep at it(which looks like waiting on premake4 to finish 4.4 beta)?

As far as i have experimented, Box2D compilation works with CMake if you unselect examples.

Cmake won't work at all for me either.  It tells me I need to add 'cmake_minimum_required(VERSION 2.' to the beginning of the cmakelists.txt file, but it has version 2.6 required there already and I've been unsuccessful at editing this file and my $PATH variable correctly to make adjustments.

I'm very sorry for not providing ready-libraries for linux, because i'm not familiar with linux.
So to solve this problem i made the project open-source to let anyone build his own version under the system that he is working on .
But maybe in the next versions of SFBL,I'll try my best to provide ready-libraries for The most used systems .

Well I've started working on it, but I've never compiled a library without the use of a build system that configured it to compile.  I think I'm close, but still getting an error.  Not sure if I should start a new thread, but I'll post it here for now :

Code: [Select]

/usr/bin/g++   -c  "/home/spirro/C++Work/sfbl/sfbl.cpp" -g -O0 -std=c++11 -Wall  -o ./Debug/sfbl.cpp.o -I. -I/usr/include -I/usr/local/include
/usr/bin/g++ -shared -fPIC -o ./Debug/sfbl.so @"sfbl.txt" -L. -L/usr/lib/x86_64-linux-gnu -L/usr/local/lib  -lsfml-graphics-d -lsfml-window-d -lsfml-system-d
/usr/bin/ld: ./Debug/sfbl.cpp.o: relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
./Debug/sfbl.cpp.o: error adding symbols: Bad value
collect2: error: ld returned 1 exit status
make[1]: *** [Debug/sfbl.so] Error 1
make[1]: Leaving directory `/home/spirro/C++Work/sfbl'

It tells me to recompile with -fPIC, but, as you can see, that -fPIC is in there.  Now whether or not it's in the right place, I'm still unsure and checking.
