Optimize folder structure

[Barsonax]

Summary

Before releasing v4 we should consider optimizing the folder structure a bit. I propose that we introduce a separation between source code and the duality game engine.

To give a general idea the structure would look like this

root
  Assets (formerly the media folder)
  Source
   Solution.sln
   Launchers
     Gamelauncher
     Gameeditor
   Plugins
     Gameplugin
  Duality
    Data
    Plugins
    rest of the buildoutput....

Duality does use some hardcoded paths so these have to be changed to make this work.

Analysis

• Simply zipping the duality folder would work for distributing the game.
• Easier to find the .sln file
• Easier to ignore certain files with wildcards from source control as files are not mixed together anymore.

EDIT: updated example structure

After discussing with @SirePi we found out that the Media folder actually contains only temporary data that is used so that you can edit resources in external programs. The source of truth is actually still the resource itself. Might sound a bit weird since it does get updated from the media folder but thats just a trick to make it work with a external program.

@ilexp is the above correct?

To make it more clear that this is temporary data I think we should put this folder under duality/temp.

Yes and no. You can safely delete the Source/Media folder and everything will still work in Duality and the editor. You can even open or re-export most of the builtin Resources via double-click, and the sources will just be extracted again and opened.

However.

This is not true for all Resource importers that can be implemented, and not even for some that currently exist, since importing and exporting are not symmetric operations. It is possible for an import to extract relevant information and omit "design" information that cannot be recreated on export.
For example, if you write a custom audio importer that imports a high quality .wav (? No idea to be honest, I'm not an audio expert) that you use for editing, then delete it and re-export it, you'll get a compressed .ogg at the previously imported quality.
Another example are fonts - for them, there is simply no way to get back the original font files, since they are transformed into bitmap fonts on import. It's not even possible to change font size after deleting the source files anymore.

So, in summary, the Source/Media folder can actually be very important. It may be okay in some workflows and with some Resource types and importers, but in the general case, you need that folder to persist if you want to edit your already imported Resources at their original quality later on. It's somewhat robust to deletion due to export features, but it's not temporary.

On a different note:

To give a general idea the structure would look like this

Please use PascalCase for folder and file names (and avoid abbreviations of already short words) to match the current convention!

Looks good other than that. Not sure about the Assets folder though - it's better than just Media if it's outside Source, but it give people the wrong impression, especially Unity people. Some wild ideas to start:

• Source/Assets
• Import
• Duality/Import
• ?

Ah that makes sense. You always want to edit the source data for best quality.

Some more idea's

• Resources
• AssetImport

I don't think we want to put it under the Duality folder though as you don't need these files anymore when publishing your game. Makes it easier if its already separated by default.

Decided to go with Import as name and keep it in the root folder

[Barsonax]

I think for now we should keep DualityLauncher and Editor in the root folder as thats much easier to implement. Moving further discussion about this to #828
