How to Use ModuleScripts in Roblox Studio

Introduction

Hello fellow developers! Today I’ll show you how to effectively use ModuleScripts in your Roblox games. This tutorial is designed to be straightforward and practical.

What are ModuleScripts?

ModuleScripts are special scripts that help us organize and reuse code across our games. Think of them as code containers that we can access from anywhere in our game.

Tutorial

1. Creating Your First ModuleScript

-- In ReplicatedStorage
-- Name: PlayerUtilities

local Module = {}

-- Example function
function Module.CalculatePlayerSpeed(level)
    return 16 + (level * 0.5)
end

return Module

2. Using Your ModuleScript

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local PlayerUtils = require(ReplicatedStorage.PlayerUtilities)

-- Now you can use your module functions
local speed = PlayerUtils.CalculatePlayerSpeed(5)
print("Player speed:", speed)

3. Best Practices

  • Place modules in ReplicatedStorage for easy access
  • Use descriptive names for your modules and functions
  • Keep each module focused on one specific purpose
  • Always return your module table at the end

4. Real-World Example

Here’s a practical example of a combat system module:

-- CombatSystem.lua
local CombatSystem = {}

function CombatSystem.CalculateDamage(baseDamage, criticalMultiplier)
    local isCritical = math.random() > 0.8
    return isCritical and (baseDamage * criticalMultiplier) or baseDamage
end

function CombatSystem.ApplyDamage(player, damage)
    local humanoid = player.Character and player.Character:FindFirstChild("Humanoid")
    if humanoid then
        humanoid.Health = math.max(0, humanoid.Health - damage)
    end
end

return CombatSystem

Tips and Tricks

  1. Use ModuleScripts for:
  • Utility functions
  • Config settings
  • Game systems (Combat, Inventory, etc.)
  • Data structures
  1. Avoid:
  • Circular dependencies
  • Putting game logic in modules
  • Over-complicated module structures

Testing

Always test your modules before implementing them:

local TestModule = require(YourModule)
assert(TestModule.YourFunction(5) == ExpectedResult, "Function failed!")
