How I Built a Multi-Track Car Racing Game in Scratch

Building a racing game in Scratch starts with a simple idea: make a car move around a track. But once you add speed control, collisions, multiple tracks, different car designs, and random track selection, the project becomes much more interesting.

For this project, I created CAR RACING THROUGH TRACKS!!!, a Scratch racing game where players can drive around three different tracks, change the car's appearance, and interact with different areas of the track.

🎮 Play CAR RACING THROUGH TRACKS!!!

🎮 What I Built

The game includes:

🚗 Player-controlled car
🛣️ Three different tracks
⚡ Variable-based speed system
💥 Collision detection
🌳 Track-specific scenery
🔀 Random track switching
🎨 Four car appearances
⌨️ Keyboard controls

Controls
Key Action
↑ Up Arrow Move forward
↓ Down Arrow Move backward
← Left Arrow Turn left
→ Right Arrow Turn right
Space Switch to a random track
1–4 Change car appearance

🧩 How the Project Is Organized
The project uses a few main elements:

car — the player-controlled vehicle
collider — used for collision detection
TREES — contains scenery for the different tracks
Three backdrops — Track 1, Track 2, and Track 3

Instead of creating a completely separate game for every track, I reused the same car and changed its position, direction, backdrop, and environment when the track changes.

🚗 Programming the Car
The car is the main gameplay sprite.

When the game starts, it moves to its starting position, points in the correct direction, and receives an initial speed value.

when green flag clicked
go to x: -179 y: -88
point in direction 0
set [speed] to 2

The important part here is the speed variable.

Instead of putting a fixed movement value into every movement block, I can change the variable during gameplay.

⬆️ Moving Forward
The Up Arrow moves the car forward.

if <key [up arrow] pressed?> then
    move (speed) steps

Because the movement uses the speed variable, the car doesn't always have to move at the same speed.

For example:

speed = 2
makes the car move normally, while:

speed = 0.5

makes it move much more slowly.

⬇️ Reversing
The Down Arrow lets the player reverse.

if <key [down arrow] pressed?> then
    move (-1) steps

The negative value makes the car move in the opposite direction.

↩️ Turning
The left and right arrow keys control the car's rotation.

if <key [right arrow] pressed?> then
    turn clockwise (5) degrees

if <key [left arrow] pressed?> then
    turn counterclockwise (5) degrees

These controls run continuously, allowing the player to drive and turn at the same time.

⚡ Creating a Speed System
One of the things I wanted was for the car to behave differently depending on where it is on the track.

I used color detection to change the speed:

if <touching color ... or touching color ...> then
    set speed to 0.5
else
    set speed to 2

When the car is on the normal driving area, the speed remains at 2.

When it touches one of the specified colors, the speed changes to 0.5.

This gives the track different types of areas instead of making the entire track behave exactly the same way.

💥 Adding Collision Detection
The project also uses a separate sprite called collider.

The basic collision logic is:

forever
    if <touching [collider]?> then
        set speed to 0

When the car touches the collider, its speed becomes zero.

This provides a simple way to make certain parts of the track behave like obstacles or boundaries.

🛣️ Adding Three Tracks
The game has three different tracks:

Track 1
Track 2
Track 3

Each track has a different layout, so the car needs a different starting position and direction.

For Track 1:

when backdrop switches to [track 1]
go to x: -179 y: -88
point in direction 0

For Track 2:

when backdrop switches to [track 2]
go to x: 179 y: 88
point in direction 180

Track 3 also has its own starting position and direction.

This is important because simply changing the backdrop isn't enough. If the car stayed in exactly the same position after changing tracks, it could appear in the wrong place.

🌳 Changing the Track Environment
The TREES sprite uses different costumes for the different tracks.

For example:

when backdrop switches to [track 1]
switch costume to [costume1]

And another track can use:

when backdrop switches to [track 2]
switch costume to [costume2]

The same idea is used for Track 3.

Using costumes this way means I can reuse one sprite instead of creating a separate tree sprite for every track.

🔀 Random Track Selection
I also wanted a quick way to change tracks.

Pressing Space selects a random track:

when [space] key pressed
switch backdrop to (pick random 1 to 3)

The pick random 1 to 3 block chooses one of the three available tracks.

So every time Space is pressed, the player can be taken to a randomly selected track.

🎨 Adding Different Car Designs
The game has four different car appearances.

Instead of creating four separate car sprites, I used multiple costumes for the same car sprite.

if <key [1] pressed?> then
    switch costume to [car_green_1]

if <key [2] pressed?> then
    switch costume to [car_red_1]

if <key [3] pressed?> then
    switch costume to [car_blue_1]

if <key [4] pressed?> then
    switch costume to [car_black_1]

This lets the player change the car's appearance while staying in the same game.

It's also a useful example of how Scratch costumes can give one sprite multiple visual variations.

🧠 Bringing Everything Together
At this point, several systems are working together:

Keyboard input controls the car.
The speed variable controls movement speed.
Color detection changes speed in certain areas.
The collider can stop the car.
Backdrop switching changes the track.
Track-specific scripts reposition the car.
Costumes change the car and scenery.
Random selection chooses a track.

None of these systems is especially complicated by itself.

The interesting part was getting them all to work together as one game.

🐛 Things I Had to Think About
A multi-track game needs more planning than a single-track project.

For every track, I need to consider:

Where should the car start?
Which direction should it face?
Which scenery should appear?
Which areas should slow the car?
Where should collision detection happen?

Adding another track would also mean adding another backdrop and updating the relevant scripts.

Planning these things ahead of time can make debugging much easier.

🧠 What I Learned
This project gave me a chance to combine several Scratch concepts.

Variables

The speed variable controls how quickly the car moves and can be changed during gameplay.

Keyboard Input

Keyboard events control movement, track switching, and car customization.

Conditions

if blocks allow the game to react to the player's actions and the environment.

Collision Detection

touching blocks can detect when the car reaches particular objects or areas.

Backdrop Events

when backdrop switches to allows sprites to react when the player changes tracks.

Costumes

Multiple costumes make it possible to change the appearance of sprites without creating completely separate sprites.

Random Numbers

pick random 1 to 3 makes the track selection unpredictable.

🧰 Public Assets
I also created a separate Scratch project for the public assets used with the racing project.

Open the CAR RACING Public Assets project

Keeping the assets separate gives the project another place for resources without mixing everything into the main game.

🚀 What I'd Add Next
There are still plenty of ways I could expand the game:

🏆 Lap system — Count completed laps.
⏱️ Race timer — Measure completion time.
🥇 Best time — Keep track of the fastest run.
🤖 Opponent cars — Add computer-controlled racers.
🚦 Starting countdown — Add a 3, 2, 1, GO! sequence.
🔊 Sound effects — Add engine and collision sounds.
🏁 More tracks — Create additional layouts.
🎚️ Difficulty levels — Make different levels of challenge.
🎮 Try the Game

If you want to see how all of these systems work together, you can play the finished project on Scratch:

I also created a video tutorial showing the project:

For the more detailed step-by-step version, you can also link your Blogger tutorial and Instructables guide here once they're published.

💡 Final Thoughts
This project started with a simple idea: make a car that can race around a Scratch track.

As I worked on it, I added multiple tracks, keyboard controls, speed changes, collision detection, different car costumes, and random track selection.

One thing I like about Scratch is that you don't need to build the entire game at once.

You can start with one mechanic — such as making a car move — and gradually build additional systems around it.

That's what made this project useful for me as a learning experience:

Start small, make it work, and then keep adding features.

ECO AI TRACKER

MASTER CODING ORGANISATION — Fri, 17 Apr 2026 04:25:59 +0000

This is a submission for Weekend Challenge: Earth Day Edition

What I Built

I built Eco AI Earth Tracker 🌍🤖 — a gamified web application designed to encourage eco-friendly habits in a fun and interactive way.
Instead of just reading about sustainability, users actively participate by completing eco actions like recycling, saving water, and planting trees 🌱
Each action increases their score and updates:
• A dynamic Earth health system (from “weak” to “thriving”) 🌍
• A badge progression system 🏆
• A simple AI-style Earth Advisor chatbot that gives eco tips 🤖
• A client-side leaderboard that ranks players based on their eco actions
The goal of this project was to make environmental awareness more engaging, visual, and interactive.

Tech Stack
• HTML – structure
• CSS – responsive UI and styling
• JavaScript – game logic, chatbot, interactions
• LocalStorage – saving scores and leaderboard data locally
• Canvas Confetti – celebration effects 🎉

How I Built It

I built this project using a fully frontend approach with HTML, CSS, and JavaScript.
The core idea is a feedback loop system:
User actions → Points → Visual feedback → Progression
Key features include:
• A scoring system that tracks eco-friendly actions in real time
• A dynamic Earth health bar that visually reflects user impact 🌍
• A rule-based chatbot that responds to sustainability-related queries 🤖
• A client-side leaderboard system using LocalStorage to simulate competition 🏆
• UI enhancements like confetti animations and sound feedback for engagement
The design is fully responsive and works smoothly across mobile and desktop devices.
AI was used as a helper tool for small parts of logic and chatbot responses, while the overall structure, design, and integration were built manually.
