Packages Guide

Packages are pieces/components of your server with ability to contain Lua scripts to interact with the game, define loading screens or maps.

Folder Structure​

All Packages must go under Server/Packages/ folder. Each Package is a folder under that.

They can contain the following folders: Server, Client and Shared. Only Client and Shared folders will be sent and loaded by the clients when they connect.

Each Package which contains Lua scripts must have a file called Index.lua inside Server, Client or Shared folders, this is the only file which will be triggered when the Package is loaded, this file is responsible for including other files and starting up your functionalities.

Package Configuration​

Packages have a configuration file in the root of the package folder, called Package.toml, in this file we can setup all pertinent settings related to the Package. Each Package Type has it's own configuration file format.

They all share the same header [meta], which contains the following settings:

_meta.toml

Package Types​

We have 4 types of packages: script, game-mode, map and loading-screen, each one with with a specific functionality and an unique purpose:

script​

Script is a normal Package type, which can load Lua script files, you can load as many script Packages as you want. They are defined in the packages entry of the Server Config.toml.

Package.toml

game-mode​

GameModes are like script packages but you can only load one game-mode package at once. They are defined in the game_mode entry of Config.toml.

They are used when you are creating full games which cannot be loaded with other full games packages.

Package.toml

loading-screen​

Loading Screen is a special Package type which is loaded during player's loading to display a custom Loading Screen as HTML. They are defined in the loading_screen entry of Config.toml.

It must have an index.html in the root. Please refer to Loading Screen for more information.

Package.toml

map​

Map is a special Package type which defines the configuration of a Map entry. They are defined in the map entry of Config.toml.

It contains all functionalities from a script, being able to execute scripts as well. With the addition it is used to load a map, having the options to have custom data and spawn points defined on its Package.toml natively.

tip

As nanos world server is not aware of Unreal or it's Assets, we need to somehow say to the server where are the scriptable part of the map, such as Spawn Points, Props locations, Weapon locations and so on.

It is a recommended approach to implement all Props, Weapons and Vehicles spawn locations in your Map Package Server/Index.lua and define all Player's Spawn points in the Package.toml file.

spawn_pointsmapList of Spawn Points in the format { location = "Vector()", rotation = "Rotator()" }, ... which can be accessed through Server.GetMapSpawnPoints()
custom_datamapList of Custom Data which can be accessed when this Map is loaded. See more here

Custom Settings​

GameModes can define Custom Settings in the [custom_settings] section to be set when creating a new game through main menu, or set when starting the server with the command --custom_settings "var1 = value1, var2 = value2, ..."

The values defined can be accessed through the method Server.GetCustomSettings().

List of Types​

Custom Data​

Maps can define Custom Data in the [custom_data] section.

The values defined are loaded when this Map Package is loaded and can be accessed through the method Server.GetMapConfig().

Usage Example​

[custom_data]
my_key = 123
my_another_key = "hello world!"
my_array = [ "whoa", "yeah", 123 ]

Ignoring Client Folders​

Sometimes you want to ignore some folders from being sent to the clients (e.g. auto generated folders from Node.js HTML ones).

To make the server ignore it you just need to add an .ignore file in the root of that folder. Simple as that 😉.

Logo Image​

It is possible to have a custom image to be displayed in the Vault. For that, add a file called Package.jpg besides the Package.toml with the image you wish. The recommended size is 300x150.

tip

Package Images are only used if your package is not on the Vault. Also it is not recommended to upload Packages with the Package.jpg file as this is not used and only bloats the Package size.
