LÖVE

i'm starting using this tool, and I found very cool how the engine works etc, but I want to know, how you guys merge the zip and the executable file into one file?? I mean, its a very cool thing, I just want to know how it works

There are quite a few ways to do it... As of yesterday, this web based way is one of the easiest.

Well, this isn't what I meant. I know how to do it, i just asked how it works

Then you want this, specifically the "Creating a Windows Executable" part.

Edit: To answer your question even more deeply, windows executables have headers, meaning the start of the file is what matters when you execute it, and zip archives have footers, meaning the most relevant stuff is at the end; You merge the zip onto the end of the exe, so this is how it'll look: Effectively, neither interferes with the other in any way.

Edit2: If you want to know how löve actually accesses the zip file that's welded to it's butt, you want to see the source, more specifically, /src/modules/filesystem/physfs/Filesystem.cpp and /src/scripts/boot.lua

Thank you zorg !

Edit: So its actually a virtual file system??

As I recently discovered, it uses PhysicsFS, http://www.icculus.org/physfs/ which is a virtual filesystem library.
