Developing Schema

= Getting Started = First of all, you will need a good text editor such as Sublime Text 3 or Atom

Head over to GLua Highlighters to know how to highlight the Garry's Mod Lua language in these text editors. After that, you'll be ready to start developing the schema.

It is recommended to start with a Sample Schema, such as The 1.1-beta sample schema, in order to get a proper layout.

= Initial Setup =

Make sure that you have the Nutscript framework already installed in the gamemodes folder (rename it to nutscript). In the same gamemodes plugin, place/create your schema folder, and name it as the name of your schema (hl2rp/cityrp/scprp) Example

= The Schema Folder =

Within the Schema folder, you must have 3 additional folders: gamemode, plugins and schema, and one .txt file named identically to your schema name (that is, if your schema is called hl2rp, the txt must also be called hl2rp.txt)

'''As a Rule of Thumb, you should not modify the gamemode folder at any point. Please look at pre-existing schemas and copy the gamemode folder from there.'''

The plugins folder is used to install additional plugins to the schema.

The schema folder contains the core files of your schema.

The .TXT file
The .txt file contains information about your gamemode. It is necessary for your gamemode to be recognized by Garry's Mod.

The contents should be as follows:

"sample-schema" {	"base"		"nutscript" "title"		"Sample Schema" "author"	"Pilot" "menusystem" "1" }

Where sample-schema is replaced by the name of your schema, title is the presented title of the gamemode as seen by the gamemode selection bar on the bottom-right corner of the menu, and author is the name of the schema's author. menusystem defines whether the gamemode/server should appear in the multiplayer server list.

= The Schema Folder =

Within the schema folder, you must have 2 crucial folders: items and factions, as well as a crucial file called sh_schema.lua

The Factions Folder
The factions folder is used to create new factions playable on your gamemode. Each faction is represented by their individual file.

For example, if you want to have 3 factions called "Citizen", "Police" and "Insurgents", you would have 3 files within the factions folder sh_citizen.lua sh_police.lua sh_insurgents.lua

Each file must contain the following code:

FACTION.name = "Custom Faction" -- the name of your faction as it appears in-game FACTION.desc = "Custom faction for only some people to use." -- the faction's description, as seen in the character creation screen FACTION.color = Color(255, 0, 0) -- the faction's color, as it appears in the scoreboard FACTION.isDefault = false -- If this is set to true, anyone can create a character within this faction. If false, players would require a whitelist, or a character would require a transfer FACTION.pay = 40 -- The default pay received every period of time. FACTION.isGloballyRecognized = true -- Used by the recognition plugin. If this is set to true, characters within the faction are automatically recognized.

FACTION.weapons = { -- SWEPs that are given to members of the faction. Be advised that these are not items, rather SWEPs, therefore they do not fill the inventory, and cannot be dropped. "nut_stunstick" }

FACTION.models = { -- default models available to the faction. The larger the list here, the bigger the options of models are for players when creating a new character "models/police.mdl", "models/alyx.mdl" }

FACTION_CUSTOM = FACTION.index -- mandatory, this allows the faction to be indexed in code elsewhere.

More information and options available for factions is available here

The Items Folder
The items folder contains all the items that your schema provides.

There are 2 methods to adding items to your schema: single file items or via a base

Single File Items

You can add an item as a single file by creating one in the items folder directly. For example, if you want to create a potato item, you would create a new file called sh_potato.lua

Inside the file, you must have this code ITEM.name = "A Potato" -- item name ITEM.desc = "Boil em, Mash em, Stick em in a stew." -- item description ITEM.price = 0 -- the default price, used by vendors and business tabs, for instance ITEM.model = "models/props_junk/Shoe001a.mdl" -- the item's model ITEM.category = "Other" -- the item's category ITEM.uniqueID = "potato" -- optional field, used for each of reference in code -- you may add additional custom information that can be used by functions that use the item ITEM.health = 10

If you want your items to have functionality, you may add functions via ''ITEM.functions. ''. For example ITEM.functions.use = { name = "Consume", --Name of the function, if this doesn't exist it'll use "use" tip = "Consume the item.", --Tip when hovering over the function icon = "icon16/cup.png", --Icon for the function onRun = function(item, data) item.player:EmitSound("items/battery_pickup.wav") --Play a cool sound item.player:SetHealth(item.player:Health + item.health) --Give health to player when they consume item.player:notifyLocalized("You consume "..string.lower(item.name).." for "..item.health.." health.") --Send message to player return true	-- This is optional. Returning true in the function deletes the item from the inventory. This is useful if you want single-use items, however, if you want to avoid that, remove the return end }

Using a base

Using a base is useful if you want multiple items that function relatively identical, such as foods or weapons

To create items via a base, you need to create 2 folders: base and a folder with the base name. For example, if I want to create a food item base, I would have 2 folders named base food

Inside the base folder, create a lua file called the same as the target base folder (for instance if I am creating a food item base, I would create a file called sh_food.lua)

Inside this new file goes the default information of the item. Items defined within the target base folder will inherit all the values and functions from this base file.

Let's create a food base ITEM.name = "Food Base" ITEM.model = "models/Gibs/HGIBS.mdl" ITEM.desc = "Tasty food, or tasy drink." ITEM.width = 1 -- used by the gridinv plugin, this allows to modify the size of the item within the inventory ITEM.height = 1 -- used by the gridinv plugin, this allows to modify the size of the item within the inventory ITEM.category = "Food" ITEM.health = 0 ITEM.action = "consume"

--- Purpose: Create a function that these items will use. ITEM.health and ITEM.action were parameters that I created. --- ITEM.functions.use = { name = "Consume", --Name of the function, if this doesn't exist it'll use "use" tip = "Consume the item.", --Tip when hovering over the function icon = "icon16/cup.png", --Icon for the function onRun = function(item, data) item.player:EmitSound("items/battery_pickup.wav") --Play a cool sound item.player:SetHealth(item.player:Health + item.health) --Give health to player when they consume item.player:notifyLocalized("You "..string.lower(item.action).." "..string.lower(item.name).." for "..item.health.." health.") --Send message to player end }

Now, in the food folder, we can create as many different food items as we please, and each will inherit these default values.

In the food folder, I will create a milk item. Call it sh_milk.lua

ITEM.name = "Milk" ITEM.model = "models/Gibs/HGIBS.mdl" ITEM.desc = "Full fat cow's milk." ITEM.width = 1 ITEM.height = 1 ITEM.health = 5 ITEM.action = "drink"

The new milk item will inherit everything from the food base, such as the consume function, however, we editted some values, such as health and action, so when the consume function is used on the item, it will use these values instead.

If you want multiple bases, create individual files in the base folder, and a new folder for each base type.

= The sh_schema.lua File =

The sh_schema.lua file is a crucial part of the schema. Upon creating it, enter the following code: SCHEMA.name = "Cool Schema" -- the Name of your Schema, as it appears in-game SCHEMA.author = "You" -- the Author of the schema SCHEMA.desc = "A schema for the people to learn from." -- A brief description of what the gamemode is about

nut.currency.set("$", "dollar", "dollars") --Symbol, singular tense of currency, plural tense of currency

While you can contain all of your code within this one file, you may want to create additional files in the schema and spread the code among them, for convenience and security. To do this, use the following: nut.util.include("sh_commands.lua") -- this allows code within the sh_commands.lua file to be readable by the schema. nut.util.includeDir("hooks") -- this allows all files within the hooks folder in the schema folder to be readable by the schema

Keep in mind that if you try to use functions or variables defined in these external files before they are included in the schema, they will not be available.

Keep in mind that if you want to add folders that are default to nutscript, such as classes, meta or libs, it is not necessary to include them.
