* pkgs/build-game: Add unzip to nativeBuildInputsaszlig2017-09-131-2/+2
| | | | | | | | | | | A lot of games come as a Zip archive, so let's add it to nativeBuildInputs by default so we no longer need to deal with that for every single game. This also removes that line from Invisigun Heroes, so the package now is pretty much minimal and very clean :-) Signed-off-by: aszlig <aszlig@redmoonstudios.org>
* pkgs/build-game: Try to evade tarbombsaszlig2017-09-131-1/+21
| | | | | | | | | | A lot of games (especially Unity games) come as a tarbomb, so in order to avoid having those files all over the place we now create an additional directory before unpack and set the sourceRoot to that if it's a tarbomb and if that's not the case set it to the single file within that directory.

* pkgs/build-unity: Switch to using buildGameaszlig2017-09-131-23/+19
| | | | | | | | | | | Now we no longer need to invoke patchelf by ourselves and all of the dependencies are patched automatically. I've added gtk2-x11, gdk_pixbuf and glib to buildUnity as well, because after inspecting other Unity games they seem to require the same libraries as well.

* pkgs/build-game: Add runtimeDependencies attributeaszlig2017-09-133-11/+23
| | | | | | | This allows us to add libraries to the RPATH despite being required by the respective game. By default there is only PulseAudio at the moment. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
* pkgs/games: Add a new buildGame functionaszlig2017-09-133-0/+178
| | | | | | | | | | | | | | | The main functionality for this function is to gather missing dependencies in ELF executables and shared libraries and using patchelf to set the right RPATH. All of the dependencies are searched based on what we have in one of the buildInputs variables, so all we need to do is list them in there. One thing that's still left to solve is adding libraries to the RPATH which are only required at runtime. An example for this would be the pulseaudio library.

* pkgs/build-unity: Create desktop entryaszlig2017-09-101-2/+19
| | | | | | | | | | | | This automatically creates a desktop entry based on the given fullName and the standard path for the icon (Resources/UnityPlayer.png). Well, at least I hope that the icon path is standard, but we'll see once we use buildUnity for more games. Tested using Plasma 5 for Invisigun Heroes.

* pkgs/build-unity: Wrap binary instead of linkingaszlig2017-09-101-2/+4
| | | | | | | | The executable of Unity games at the moment is unable to find its own path if it can't do a stat() on argv[0]. So wrapping the program helps here for now. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
* games/invisigun-heroes: Factor out into buildUnityaszlig2017-09-102-0/+54
There are a lot of Unity games out there, so it's a good idea to have a generic builder just for Unity, which we then can apply to a lot more games. Right now this is a pretty basic abstraction which I've only tested with Invisigun Heroes. Signed-off-by: aszlig <aszlig@redmoonstudios.org>
