SS14 and RobustToolbox are split into several different projects. The main ones you'll care about are the
Server projects. Other projects are for smaller things like integration tests, benchmarks, or database-specific code.
Server are each packaged into different 'assemblies', which is basically .NET talk for executables or shared libraries.
Client project in both Robust and SS14 contains client-specific code, like UI. This assembly is only sent to the client, the person actually playing the game.
Server project contains server-specific code that no specific client should be able to interact with, like atmospherics or botany. This assembly is only located on the game server.
Shared project contains shared code that can be used by the client or the server. This assembly is not executable, and it relies on the client or server to call functions in it or use data classes located within it. The purpose of shared is to allow for network prediction (where the client and server run the same code, to make things smoother) as well as to specify shared data classes, like network messages, so that the client and server can speak to eachother effectively.
Shared code is only allowed to access other shared code, not client or server code. However, client and server code are always allowed to access shared code.
In SS13, all game code is under
code/modules, and thrown haphazardly around in there with no real sense of purpose. In SS14, we first delineate by which game system we're working with (atmos/botany/buckling, etc) and then by the classes needed for it.
Content.Server all follow this organization. RobustToolbox's equivalents do not currently, but will in the future.
This structure should hopefully be very clear after working with it or seeing examples.
A real example, under
The resources folder is another area where we hope to improve over the organization structure of SS13 codebases.
New folders should usually only be created for a new parent type. If you find something that can be pulled out into a parent prototype, it should go in its own folder.
Parent prototypes should be contained in
base.yml in this folder, while other prototypes go in a different file.
Not everywhere is organized like this; however, the
Structures folder is.
This was chosen to make the directory structure mirror the prototype inheritance tree, making it obvious where to place new prototypes as well as being fairly unambiguous when choosing to create new folders.
