RegionService — The Modern Replacement for Region3

By TrooperKing3005 | Version 1.0 | 2025

Overview

Tired of the limitations and hassle of Region3 and FindPartsInRegion3?
Meet RegionService, a streamlined, event-driven, and flexible module designed to handle 3D regions effortlessly — no more looping through parts or complicated math!

With one simple function call, create custom regions, listen for player entry and exit events, and build responsive gameplay areas with ease.


Features

  • Create regions by name, position (CFrame), and size (Vector3)
  • Automatic tracking of players entering and leaving regions
  • Event handlers: PlayerEntered, PlayerLeft for clean and readable logic
  • Debug visualization with customizable options
  • Supports any number of regions simultaneously
  • Lightweight and easy to integrate into any game
  • Pause/resume tracking for flexible control
  • Clean API inspired by ProfileService for familiarity and ease of use

Example Usage

local RegionService = require(game.ReplicatedStorage.RegionService)

local speedZone = RegionService:CreateRegion("SpeedZone", workspace.SpeedPad.CFrame, workspace.SpeedPad.Size)

speedZone.PlayerEntered:Connect(function(player)
    player.Character.Humanoid.WalkSpeed = 24
end)

speedZone.PlayerLeft:Connect(function(player)
    player.Character.Humanoid.WalkSpeed = 16
end)

Hey, this is a pretty cool module! Since you plan on expanding it to work with more part shapes, I can definitely help you there!

Feel free to just steal the “point is in part” functions, they include the functionality of blacklisting certain axis like you currently use (by default they check for complete containment). In that module I have a “point is in part” for every single part type
