Roblox Racing Game Level 2: Code Laps, Timers and Leaderboards

A racing game needs more than a fast car. It needs rules, timing and a way to decide who wins. In this eight-week Level 2 course learners who have built a basic racing game learn to code complete race systems in Roblox Studio.

Learners start by designing a race track with invisible checkpoint gates. They script the gates so the game knows each player's progress and can stop players from skipping parts of the track. Next they code lap counting and display each player's current lap on screen. Learners then create a start countdown with traffic lights and lock cars in place until the race begins.

In the middle weeks learners build a race timer, record each player's finish time and display results on a leaderboard. They add boost pads, ramps and pit stops, using code to temporarily change car speed. Later weeks cover race modes such as time trials and multi-player races, and learners create a lobby where players choose a car before the race starts.

The teacher explains each system with diagrams and live coding, and learners customize their tracks and rules. Classmates race on each other's tracks during playtests.

By the end learners will have a complete racing game with laps, timers and results. Learners should have built a basic racing game or know Lua events and variables.

How classes work

Each week introduces one race system with live coding and diagrams. Learners build it into their track and race classmates at the end of class.

What we'll cover

• Week 1: Track and Checkpoint Gates – Design a track with invisible gates.

• Week 2: Progress Tracking – Prevent shortcuts by checking gate order.

• Week 3: Lap Counting – Count and display laps.

• Week 4: Start Countdown – Lock cars until a traffic-light countdown ends.

• Week 5: Race Timer and Results – Record finish times on a leaderboard.

• Week 6: Boosts and Ramps – Change speed temporarily with code.

• Week 7: Race Modes and Lobby – Add time trials and car selection.

• Week 8: Grand Prix – Race on classmates' tracks and polish.
