Learning Mission Example: Debugging the Traffic System
Mission Script (Pseudo-Code)
pseudo
Copy code
Mission: DebugTrafficSystem
Objective: Fix the traffic lights in Tech District

Steps:
1. Player accesses traffic control terminal
2. Player sees the current faulty code in the CodePad
3. Player identifies and corrects the logical errors
4. Player submits the code for real-time testing
5. If the code works, traffic flow is normalized; if not, player receives hints

Faulty Code:
if (carAtIntersection && light == "green") {
    stopCar();
} else {
    goCar();
}

Correct Code:
if (carAtIntersection && light == "red") {
    stopCar();
} else {
    goCar();
}
