_{Project 3 — Step 4 of 4}

⭐ Step 4 — Smoke trail

➡️ Add a trail of orange smoke puffs behind the rocket.

Inside the same for loop, before drawing the rocket, draw a small orange dot just below it. Each loop turn leaves another puff behind, building up a trail.

✏️ What to type

At the top of the for step in range(50): loop, before the rocket drawing lines, add:

    pen.penup()
    pen.goto(rocket_x + random.randint(-10, 10), rocket_y - 20)
    pen.color('orange')
    pen.dot(15)

(Keep it pushed in by 4 spaces so it stays inside the loop.)

Tap ▶ Run. You should see a stack of silver rocket dots with orange smoke beneath each one. 🔥🚀

🧩 Ideas to try

• Make the smoke a different color (try 'red' or 'gold').
• Slow the rocket down by changing + 8 to + 4.
• Add a fuel variable: fuel = 50 then for step in range(fuel): — ask the player for fuel with input!
