Roblox Coding Basics

How to Access Projects

Your ninja's Roblox game is ready to open at home. Here's how in four steps:

  1. Download your ninja's project file. Your ninja's Sensei uploaded each week's finished Roblox files to Google Drive on Friday. Pick the week your ninja attended:
  2. Install Roblox Studio. On any computer or laptop, search "Roblox Studio" and download from the first link (it's free).
  3. Open the file with Roblox Studio. Double-click the file you downloaded, or open Roblox Studio and use File → Open. Sign in to a free Roblox account when prompted.
  4. Play, read the code, keep coding. Roblox Studio loads an exact copy of your ninja's game — including every Lua script they wrote this week. From here they can play it, tweak the scripts, and keep coding from home.

What We Covered This Week

Throughout the camp, Ninjas wrote real Lua scripts — the programming language behind every Roblox game — to build, modify, and "hack" their own creations. Click any topic to expand.

Roblox Studio Basics & First Lua Script
  • Navigated Roblox Studio — Workspace, Properties, Toolbar, and Explorer panels
  • Built a Parkour Map with multiple obstacle types, custom colors, materials, and a finish-line bonus
  • Wrote their first Lua script — opening the Script Editor, running print("Hello world!"), then changing part properties through code
  • Learned core Lua syntax habits — Tab autocomplete, spelling and capitalization that matter, reading red-underlined errors in the Output Panel
Code-Generated Worlds — Functions, Loops & Vectors
  • Used Instance.new() to spawn parts from scratch with code instead of dragging them in
  • Built the Leaning Tower of Bricks — wrapped the spawn code in a function, called it inside a for loop, and added wait() + BrickColor.Random() for color variety
  • Remixed the script into Dominoes — used Vector3 for orientation and passed a parameter into the function so each part landed in a new spot
  • Hacked the dominoes script into a bridge across a chasm with anchored, randomly-colored parts
Events, Booleans & Hacking the Color Game
  • Learned Touched events — code that runs the moment a player touches a part
  • Built a Hidden-Button Challenge — find the trigger, touch it, and a code-generated path appears (with a Boolean flag that stops it from spawning twice)
  • Read and modified the Color Game's script — explored tables (lists of items) and the :GetChildren() method
  • Remixed the Color Game with new tile layouts, added obstacles, and patched a bug using an if statement + a hidden secret object
Building, Scale & Terrain Design
  • Designed a House Project at proper scale with a dummy avatar for reference
  • Used pro-creator shortcuts — Duplicate, Group, Ungroup, and Anchor — to build faster and cleaner
  • Sculpted custom landscapes with the Terrain Editor — mountains, valleys, caves, water, and painted materials
  • Combined everything into one connected world that became the foundation for the capstone
Trap Scripts, Capstone & Publishing
  • Explored the Toolbox — found and added pre-built models to dress the world (10+ objects)
  • Wrote trap scripts — damage traps that activate on touch, secret doors that open with a hidden switch, and false floors with invisible tiles
  • Combined everything into a Capstone Game with original Lua scripts, terrain, and toolbox details
  • Published the game to Roblox — parents played it live at the Camp Celebration and earned a Certificate!
