FEATURE LIBRARY

Organized by game feature

Each feature starts with the Studio setup steps, then gives students one complete script to copy. The goal is to help students build working behavior first, while gradually connecting the script to familiar programming ideas like variables, conditions, loops, and functions.

Ready to use

Respawn an Object

Spawn a fresh home copy when a car, plane, horse, or other moving object leaves its starting place.

Ready to use

Race Checkpoints

Guide racers through 10 checkpoints in order with messages, sounds, flashes, and floating numbers.

Ready to use

Score Pad

Give players PadScore points when they touch or drive into a pad, then hide it for 10 seconds.

Coming soon

Finish Line Timer

Record when a player reaches the end of a race.

READY FEATURE

Respawn an Object

Use this when a player drives, rides, or moves an object away from its starting place. When no matching object is within 25 studs of home, Roblox waits 5 seconds and spawns a fresh copy at the original location. The object that was driven away is left alone.

WORKFLOW FIRST

Put the object in Workspace exactly where it should start.
Duplicate that object and move the duplicate into ServerStorage.
Make sure both objects have the exact same name.
Open ServerScriptService, add a new Script, and paste the code below.
Change only OBJECT_NAME, then press Play to test.

WHY IT WORKS

The script first looks for common moving parts, like a DriveSeat, VehicleSeat, Seat, or HumanoidRootPart. It checks whether any copy with the same name is still near the start, then clones the backup copy from ServerStorage only when the home spot is empty.

To respawn three different cars, make one script for each car and change OBJECT_NAME in each script.

COMPLETE SCRIPT

Paste into ServerScriptService

-- Put this Script in ServerScriptService.
-- Put a backup copy of the object in ServerStorage.
-- Roblox uses -- for comments. Python uses # for comments.

local ServerStorage = game:GetService("ServerStorage")

-- PART 1: Student settings
-- STUDENT CHANGE: Replace MyObject with the exact name of your car, plane, horse, or model.
local OBJECT_NAME = "MyObject"

-- STUDENT CHANGE: Try 2 for a faster respawn, or 10 for a slower respawn.
local RESPAWN_SECONDS = 5

-- STUDENT CHANGE:
-- Try a smaller number like 10 to respawn sooner.
-- Try a bigger number like 50 if the object is large.
local HOME_RADIUS = 25

-- PART 2: Good parts to track on moving objects
-- You usually do not need to change this list.
local TRACKING_PART_NAMES = {

READY FEATURE

Race Checkpoints

Use this when students build a simple race path. Players must touch Checkpoint1 through Checkpoint10 in order. Correct checkpoints show a green message, play a sound, and flash. Wrong checkpoints show a red message and tell the player which checkpoint to find next.

WORKFLOW FIRST

Create a Folder in Workspace named RaceCheckpoints.
Add 10 Parts inside the folder named Checkpoint1 through Checkpoint10.
Place the Parts around the map in the order racers should drive through them.
Make each checkpoint large enough to touch, then keep it transparent and non-colliding.
Open ServerScriptService, add a new Script, and paste the code below.

WHY IT WORKS

The script gives each player their own next checkpoint number, so multiple students can race at the same time. It only counts a checkpoint if it is the exact next one in sequence.

It also creates floating number labels, screen messages, sounds, and checkpoint flashes from the script, so students do not need to build those effects by hand.

READY FEATURE

Score Pad

Use this when students want a simple scoring object on the track. A player can walk into it or drive into it to gain PadScore. The pad flashes, plays a sound, disappears for 10 seconds, and then returns for the next player.

WORKFLOW FIRST

Create one Part in Workspace named exactly ScorePad.
Put it anywhere students should score a point.
Duplicate it around the map without changing the name.
Open ServerScriptService, add a new Script, and paste the code below.
Press Play and touch or drive into the pad to test the PadScore leaderboard.

WHY IT WORKS

The script finds every Part named ScorePad, so students can add more scoring objects by duplicating the same pad. The first valid touch scores, then the pad turns off until it respawns.

It uses PadScore instead of Score, so it can run beside checkpoint or target games without mixing those points.
