Easy way to load files from zip
« on: February 05, 2018, 10:27:44 pm »
Hello!

When it comes to streams and stuff im kinda helpless.

Im searching for an easy way to load for example .tga files from a zip file.

Forgive me for being such a noob.
Ive googled hours and checked every single thread in subforum System.
Without success of course.

Thanks in advance!

Best regards,
Bizarreofnature

See https://icculus.org/physfs/ and https://github.com/SFML/SFML/wiki/Source:-PhysicsFS-Input-Stream

The code on wiki is mine from a few years ago and a bit bad. I might rewrite it today. Done.

Sorry for late respond and thank you very much for your help. This is awesome. So easy.

But I have a problem. I cant find this file:

Quote
#include "PhysFsStream.hpp"

The wiki page has 3 files in it: PhysFsStream.hpp, PhysFsStream.cpp and example.cpp. You should create all three and copy the contents from it. You'll also need to get physfs library itself from somewhere else too (easiest is to build it yourself, since it doesn't provide prebuilt packages for a while now).

And this is the point where im clueless again.
I downloaded CMake but i have no idea how to build these libraries.

Is there any tutorial how to build physicsfs?

How did you get it to work without building it?

By including all files to my project... which is ugly and noobish.
Id really like to make libs and include them the right way.

Just open CMake GUI, drag CMakeLists.txt into it and then pick your compiler and generate files for it (for VS it'll be a sln with few projects).

Thank you.

So Ive created physfs.lib and included it to my project.

And now:

Quote
PHYSFS_AddToSearchPath ("Game.zip", 1);

is not defined.  :(

Once you have the lib and headers the process to use them is the same as with SFML.

I know.. but for some reason it doesnt work. Let me write it down:

Quote
#include <PhysicsFS/physfs.h>

this is how i include it to my project.

Quote
PhysicsFS/lib/

the place of the lib files

Quote
PhysicsFS/include/PhysicsFS/

place of my headers

And the vs config is EXACTLY the same as the sfml one.

The lib should also be added to AdditionalDependencies in linker input settings.

Yes i did, however its not working.
I wonder.. is it really only one single lib? i have a normal one and a static one.

Yes, it's a single library. It just can be built as dynamic or static but you need one one of them.
