How to run a coding class with the Code Builder curriculum

Guide

Start Teaching
with Code Builder

Code Builder is an in-game coding education platform where students open a block coding window during Roblox gameplay and give commands to their agent. With no separate install, students can start coding right inside a screen they already know.

This manual gives elementary and middle school teachers and coding instructors what they need to run the curriculum as a field trip or after-school class — what to prepare, how to run it, and each stage's learning goal.

What You'll Need

Devices

PC (keyboard) or mobile/tablet. One per student is ideal; pairs of two also work

Internet Connection

A stable Wi-Fi connection is needed to reach Roblox servers

Roblox Accounts

Have students (or teams) log in ahead of time to save class time

Share the Play Link

First Launch

The 5-Step Onboarding Tutorial

New players automatically see these 5 cards on first launch. Students can follow along on their own, but knowing them ahead of time helps you answer questions fast.

1

Welcome to Code Builder!

Assemble blocks to move your character. Your character won't always listen perfectly.

2

Open & Close

Press C (PC) or the <> button (mobile) to open and close the Code Builder.

3

Select a Character

Use the < / > buttons in the header to pick which agent to control.

4

Block Palette

Drag blocks from the left onto the canvas. Switch categories using the tabs.

5

Give It a Run!

Press Run to execute your code, and Reset to move the agent back to its start position.

The Blocks

7 Available Blocks

Move Forward

Action · Moves the agent forward one tile (8 studs)

Turn Right

Action · Rotates the agent 90 degrees to the right

Place Flower

Action · Plants a flower at the agent's current position

Repeat

Loop · Runs the blocks inside N times (max 20)

If Obstacle

Conditional · Runs the blocks inside only when an obstacle is ahead

Define Function

Function · Names and defines a group of blocks

Call Function

Function · Runs a previously defined function

Move → Plant → Repeat → Condition → Function

Stage Learning Goals & Progress Conditions

When a student reaches the goal tile or plants the target number of flowers, the system automatically advances them to the next map — no manual checking required. The curriculum is a gradual course toward completing your own garden, and it will keep expanding and improving over time.

Tips

4 Tips for a Smoother Class

Automatic Progression

When students reach a goal (tile or flower count), the system automatically moves them to the next lesson's map — no manual checking needed

Motivate with the Leaderboard

A lesson-progress ranking shows in the top-left of the screen. Seeing each other's progress naturally motivates students

Use the Reset Button

If an agent gets stuck or makes a mistake, Reset only resets its position — any flowers already planted stay put

Safe Command Execution

The server validates every command so only allowed blocks run, keeping students safe from unexpected behavior
