C Module

C Module is a Package type that allows extending the functionalities of nanos world Scripting API

C Modules allows you to extend the functionality of the nanos world scripting API on the server side. Actuellement, seuls les modules C sont pris en charge.

attention

Sachez que cette partie de l'API de scripting est actuellement en cours de réalisation et peut être modifiée à tout moment.

attention

Comme il s'agit d'une procédure avancée, des instabilités, voire des crashs, peuvent se produire.

Creating your C Module binaries

To create your own module, fist make sure you have Visual Studio installed with Desktop development with C++ (and CMake) or any other C compiler on Linux.

Premières étapes

1. Then, clone our example module in your computer to get start with it.
2. After cloning, you will need to download it's submodules with git submodule update --init --recursive - this will download the module-sdk as a git submodule into deps/ folder automatically.

Comprendre l'exemple

The important file is under src/example.cpp:

src/example.cpp

See full example on GitHub

Compiling your C Module

Pour compiler l'exemple, suivez les étapes suivantes :

1. Create a folder called build/: mkdir build
2. Enter the build folder: cd build
3. Generate the cmake build files with cmake ..
4. Finally build it with cmake --build . --config Release

This will generate the compiled library at:

• For Windows: build/Release/example.dll
• For Linux: build/libexample.so

tip

If you intend to make your module available for both Linux and Windows servers, you must also compile the .so files in a Linux machine and deliver both library files with your Package.

Creating a C Module Package

First of all, create a new Package of type c-module, and add your .dll (windows) and/or .so (linux) files into the Package's root folder. Votre dossier devrait ressembler à cela :

Packages/
└── my-module/
    ├── Package.toml
    ├── example.dll
    └── libexample.so

Then add the name of your module library (in our case, example) to the Package.toml modules list:

my-module/Package.toml

# vault configurations
[meta]
    # friendly name
    title =                 "My Awesome C Module"
    # contributors
    author =                "Contributor Names"
    # version
    version =               "0.1.0"

# c module configurations
[c_module]
    # list of modules to load (without file extension)
    modules = [
                            "example",
    ]

Loading and Using your C Module

Now you can load the package you created as usual, by adding it to the Config.toml's list of Packages requirement or by adding it to another Package's Package.toml as dependency, e.g.:

Server/Config.toml

...
# game configurations
[game]
    # default startup map
    map =               "default-blank-map"
    # game-mode package to load (set the main game-mode package to load - you can load only one 'game-mode' package type at once)
    game_mode =         ""
    # packages list (set the packages you want to load)
    packages = [
                        "my-module",
    ]
...

Et dans votre package, vous pouvez le charger et l'utiliser :

my-awesome-package/Server/Index.lua

-- Calls the module function 'test'
-- Will print 'Hello World' on console
Console.Log(example.test())
