Utility functions available on both client and server.

cLib.GetStringTotalWords

Count words in a string.

local count = cLib.GetStringTotalWords(str)

local words = cLib.GetStringTotalWords("Hello world, this is a test")
-- Result: 6

Engine Entity Detection

cLib.IsEngineWeapon

Check if weapon class is a default GMod weapon.

local isEngine = cLib.IsEngineWeapon(weaponClass)

cLib.IsEngineWeapon("weapon_pistol")     -- true
cLib.IsEngineWeapon("weapon_crowbar")    -- true
cLib.IsEngineWeapon("m9k_ak47")          -- false

cLib.IsEngineEntity

Check if entity class is a default GMod entity.

local isEngine = cLib.IsEngineEntity(entityClass)

cLib.IsEngineEntity("item_healthkit")    -- true
cLib.IsEngineEntity("item_battery")      -- true
cLib.IsEngineEntity("custom_entity")     -- false

cLib.GetEngineEntityModel

Get the world model for engine entities/weapons.

local model = cLib.GetEngineEntityModel(class)

local model = cLib.GetEngineEntityModel("weapon_pistol")
-- "models/weapons/w_pistol.mdl"

local model = cLib.GetEngineEntityModel("item_healthkit")
-- "models/items/healthkit.mdl"

Engine Lookup Tables

-- Available weapons
cLib.EngineWeapons = {
    ["weapon_357"] = "models/weapons/w_357.mdl",
    ["weapon_ar2"] = "models/weapons/w_irifle.mdl",
    ["weapon_pistol"] = "models/weapons/w_pistol.mdl",
    -- ... etc
}

-- Available entities
cLib.EngineEntities = {
    ["item_healthkit"] = "models/items/healthkit.mdl",
    ["item_battery"] = "models/items/battery.mdl",
    ["item_ammo_pistol"] = "models/items/boxsrounds.mdl",
    -- ... etc
}

Practical Example

-- Get proper model for any item
function GetItemModel(class)
    -- Check if it's an engine item
    local model = cLib.GetEngineEntityModel(class)
    if model then return model end
    
    -- Try to get from entity/weapon
    local ent = weapons.Get(class)
    if ent and ent.WorldModel then
        return ent.WorldModel
    end
    
    local entTable = scripted_ents.Get(class)
    if entTable and entTable.Model then
        return entTable.Model
    end
    
    return "models/error.mdl"
end
