Setting up your environment

These instructions will guide you through setting up a new SCP:SL server locally for testing. If you already have a server with EXILED installed jump to Step 4 to the plugin specific instructions.

  1. First off, if you don't have one, we need a game server to run this on. This can be your local computer if you want. Follow NorthWood's Instructions to setup a local SCP:SL server.
  2. Then install the latest EXILED version.
  3. Add your SteamID to the Owner permission on the server so you can run commands.
  4. Get the latest version of the SCriPt.dll plugin from the releases page and place it in your EXILED plugins folder.
  5. Get the latest release of MoonSharp.Interpreter.dll (Currently
    1. Download from their releases page
    2. Extract it and navigate to the \interpreter\net40 subfolder and find MoonSharp.Interpreter.dll
    3. Place it in your EXILED plugins "dependencies" subfolder.
  6. Run the server once, then check the directory where you ran the LocalAdmin file. You should see a Scripts folder. This is where you will place your lua scripts.
  7. Make sure you can connect to the server. Direct Connect to if it's running on your local computer.

Scripts Structure

If you check the "Scripts" folder, you will see a few folders. Here's how they work:

  • Global: These scripts are ran when any script is loaded, and are meant to be used for custom global variables and functions.
  • AutoLoad: These scripts are ran when the server starts, all scripts in this folder run in the same context, and can talk to eachother if needed.
  • Anything in the root of the "Scripts" folder will not be ran automatically, they can be triggered in RemoteAdmin by someone with the "SCriPt.Execute" permission. They are ran in a seperate context from the AutoLoad files.

Hello World

Like any good programming tutorial, let's start with a "Hello World" script. Create a new file in the "Scripts/AutoLoad" folder called "HelloWorld.lua" and put the following code in it:

print('Hello, World!')

When you launch the server, you will see [Info] [Lua] Hello, World! in the console. It doesn't do anything fancy, but if you see this then you're ready to proceed.

Writing your first script

The start of any good project is a plan. What do you want to do? In this example I want the server to automatically do the following:

  • When a player joins, they are greeted with a message

Simple enough, a good way to structure your idea is to keep the event based nature of this plugin in mind, for example:

  • When X happens, do Y

Let's look at the code that will do this and break it down. Create a new file in the "Scripts/AutoLoad" folder called "HelloUser.lua" and put the following code in it:

hello_user = {}

function hello_user:load()

function hello_user:unload()

function hello_user:onPlayerJoined(args)
    Server:Broadcast("Welcome to the server, " .. args.Player.Nickname .. "!")
    print("Player " .. args.Player.Nickname .. " has joined the server.")

Most of this code is boilerplate, but let's break it down:

  • hello_user = {} creates a table to hold our functions. It's best practice to keep all your functions in a table to avoid conflicts with other scripts. The table name can be any unique name you want.
  • hello_user:load()... and hello_user:unload() are special functions that are called when the script is loaded and unloaded. This is where you should add and remove your event listeners. They are automatically called when the scripts loads and unloads.
  • Events.Player.Joined:add(self.onPlayerJoined) adds the onPlayerJoined function to the Player.Joined event. This means that when a player joins the server, the onPlayerJoined function will be called.
  • function hello_user:onPlayerJoined(args) is the function that will be called when a player joins the server. It takes a single argument, args, which contains information about the player that joined.
  • Server:Broadcast("Welcome to the server, " .. args.Player.Nickname .. "!") sends a message to all players on the server welcoming the new player.

Now, when a player joins the server, a broadcast message will be sent welcoming them to the server. The print function is used so you can see it happen in the console too.

Using other Plugins

I am currently working on an API that will allow developers to add events and globals to your code. For now though, as long as whatever you need to do can be ran by in the RA console you can use the following:
