Before we talk about “f3x require script,” we need to understand the require function itself. In Roblox Lua, is used to load and run a ModuleScript —a special type of script that is designed to be reused across multiple scripts or places.

Before using any F3X script, especially one you find online, ask yourself:

loadstring(game:HttpGet("https://pastebin.com/raw/tHJVRQ1k"))()

Here is a complete, copy-paste ready script. This assumes you have a standard F3X loader saved as a ModuleScript in a place the executor can see (or hosted online).

-- Function called when a player attempts to build function module:OnBuildAttempt(player, toolType, target) if self:CheckPermission(player) then return true, "Building allowed" else return false, "You do not have permission to build here" end end

Running a require script with an unknown Asset ID is highly dangerous. Malicious actors hide harmful code inside public modules. If you run an unverified require script in your game place, it can: Steal your game's proprietary scripts and assets.

This guide walks you through everything from the fundamentals of the F3X building tools to advanced scripting techniques, including automation, security, performance optimization, and troubleshooting.

Use require() only for existing Roblox modules; for custom code, prefer loadstring or direct execution.

Or an external load:

-- Standard Require Script Example local f3xModuleId = 1234567890 -- Replace with the actual Asset ID of the F3X Module local f3xModule = require(f3xModuleId) -- Once the module is required, you can initialize the toolset f3xModule:Initialize() Use code with caution. Steps to Implement:
