Before you start

Make sure Setup is finished. Your Start Platform part should be named Lobby.

Build

a three-block climbing wall and the Stage 2 checkpoint

a first obstacle that feels like the start of a parkour lab

The big idea​

A checkpoint is a save spot. If a player falls, they come back to the last checkpoint they touched.

Today you build the first climb and add a tiny sparkle when the player reaches the top. The sparkle is small, but it matters: games feel better when they react to what the player does.

New words
SpawnLocation
a pad where players can respawn
TeamColor
the color that connects a player team to a checkpoint pad
attribute
a small custom label on a part, like StageNumber
ParticleEmitter
a Roblox object that makes sparkles, smoke, or other tiny effects

Build it​

Step 1 — Set up the Stage 1 checkpoint​

Select the SpawnLocation on your Start Platform and set:

Build this part

SpawnLocation (Stage 1)

Block
Open recipe
Size
6 × 1 × 6
Color
Bright blue
Material
Plastic
Anchored
✓ Yes

Check AllowTeamChangeOnTouch. Uncheck Neutral. Set TeamColor to Bright blue.

Add an attribute:

  • Name: StageNumber
  • Type: number
  • Value: 1

In Teams, create a Team named Stage 1. Set its TeamColor to Bright blue and leave AutoAssignable checked.

Step 2 — Build the climbing wall​

Add three anchored parts in front of the Start Platform:

Build this part

ClimbBlock_Tall

Block

Size
4 × 10 × 2
Color
Medium stone grey
Material
Slate
Anchored
✓ Yes
Place
Next to ClimbBlock_Mid, tallest

Press Play and jump up the wall. Tune the spacing until it feels possible.

Step 3 — Add the Stage 2 checkpoint​

Place a new SpawnLocation at the top of the climb:

Build this part

SpawnLocation (Stage 2)

Block
Open recipe
Size
6 × 1 × 6
Color
Bright red
Material
Plastic
Anchored
✓ Yes
Place
On or just after ClimbBlock_Tall

Check AllowTeamChangeOnTouch. Uncheck Neutral. Set TeamColor to Bright red.

Add StageNumber = 2. Create a Stage 2 Team with Bright red TeamColor and AutoAssignable unchecked.

Step 4 — Add a boost sparkle​

Right-click the Stage 2 SpawnLocation -> Insert Object -> ParticleEmitter.

Set:

  • Rate -> 10
  • Lifetime -> 1
  • Speed -> 2
  • Color -> yellow or cyan

Now reaching the top feels like a little celebration.

Understand it​

The checkpoint works because the pad color and TeamColor match. The sparkle works because the Stage 2 pad has a ParticleEmitter attached to it.

This is the course rhythm: build something, test it, make it feel better.

Try this​

Learning beat

Try this

Three short experiments. Predict before you run, then test your guess.

Predict first

What happens if Stage 2's pad is red but the Stage 2 TeamColor is blue? Predict first, then test.

Compare

Try a slow sparkle rate and a fast sparkle rate. Which feels more exciting without becoming distracting?

Connect

Where else in your obby should a tiny celebration happen?

Test your stage​

  • You spawn on the blue Stage 1 pad.
  • You can climb the wall without impossible jumps.
  • Touching the red pad changes your checkpoint.
  • Resetting brings you back to the red pad.
  • The red pad sparkles.

If it breaks​

  • Reset sends me to the wrong place. Check the pad BrickColor, TeamColor, and StageNumber.
  • The climb is too hard. Move the blocks closer together or make the short block shorter.
  • No sparkles appear. Confirm the ParticleEmitter is inside the Stage 2 SpawnLocation.
Coach demo

If you have a headset or want to describe the VR idea, this wall is the perfect demo: "Imagine your hands grabbing these blocks and pulling you up." Do not ask ages 7-10 students to code hand tracking.
