Studio Launch IV

Review — your portfolio 5 min

• Four projects, each proving something different, behind one menu.
• Each has a front door and a reset; each game keeps a best score nothing clears.
• About me shows your games, never who or where you are.

Quick-fire

Your menu opens project 3 while project 2 is still playing. What stops the two running at once?

Today’s Topic 3 min

• A two-minute pitch, planned in four beats
• A fair running order, with Quiz Engine’s shuffle
• All of Level 4 in one list — twelve arcs
• A certificate, and where to go next

Learning outcome

By the end of this lesson you will be able to:

1. Present a project in two minutes: what it is, a live demo, what you learnt.
2. Name what each Level 4 arc taught.
3. Choose a next step after Scratch.

Learnt — showcase day 25 min

1 · Two minutes, four beats

Two minutes goes fast. Plan it as four beats in two lists — what you say, and for how long — and they add up to exactly 120 seconds:

• Hook (20 s) — what it is, in one sentence. “Star Rally is Brick Breaker with a ball that speeds up every hit.”
• Demo (60 s) — play it live, and say what to watch for.
• What I learnt (30 s) — the one Level 4 idea inside it, and one bug you fixed.
• Thanks (10 s) — credit anyone you remixed, then take questions.

2 · A fair running order

Who goes first? Nobody chooses — the computer shuffles the names, the fair way you built in Quiz Engine II.

define shuffle
set [n v] to (length of [running order v])
repeat ((length of [running order v]) - (1))
  set [j v] to (pick random (1) to (n))
  set [temp v] to (item (n) of [running order v])
  replace item (n) of [running order v] with (item (j) of [running order v])
  replace item (j) of [running order v] with (temp)
  change [n v] by (-1)
end
            

3 · Level 4 in one list

Twelve arcs, forty-eight lessons. Each one in a line:

1. 01–04 Sketch Pad — the Pen draws only while the mouse is down.
2. 05–08 Geometry Art — 360 ÷ sides, stars and spirographs.
3. 09–12 Music Maker — notes and beats played from two lists.
4. 13–16 Tile Maker — a level is letters in a list.
5. 17–20 Castle Climb — collision by asking the map, not the colour.
6. 21–24 Boss Tower — a phase variable runs the boss.
7. 25–28 Cartoon Studio — a cue sheet directs the film.
8. 29–32 Brick Breaker — a ball is two numbers, vx and vy.
9. 33–36 Kart Racer — sin and cos, drift and laps.
10. 37–40 Quiz Engine — a question is one line of text.
11. 41–44 Snake — a list used as a queue.
12. 45–48 Studio Launch — remix, share, show.

4 · The certificate

The certificate asks for a name and types it onto the line, one letter at a time — Quiz Engine’s letter (i) of, used for something that is not a quiz. First name only: a certificate gets photographed and shared.

ask [What name goes on the certificate? First name only.] and wait
set [name v] to (answer)
set [typed v] to []
set [i v] to (1)
repeat (length of (name))
  set [typed v] to (join (typed) (letter (i) of (name)))
  say (typed)
  change x by (8)
  wait (0.25) seconds
  change [i v] by (1)
end
            

Basic — the showcase 35 min

Step 1 — plan your pitch (8 min)

1. Pick one project from your portfolio.
2. Write your four beats on paper: hook, demo, what you learnt, thanks.
3. Rehearse once with a partner holding a timer. Cut anything over two minutes.

Step 2 — the showcase (22 min)

1. Run the running-order shuffle. Present in that order.
2. While others present, write one thing you liked and one question for each — kind, and about the game.

Step 3 — graduate (5 min)

1. Run the certificate with your first name.
2. Save your portfolio and your remix to your computer. They are yours to keep.

First name only

Make the certificate refuse a full name.

• A name with a space in it is asked for again.
• Count how many times it had to ask.

repeat until <not <(name) contains [ ]?>>
  change [asked again v] by (1)
  ask [First name only, please - no space.] and wait
  set [name v] to (answer)
end
            

A Level 4 recap quiz

Use your Quiz Engine to test the class on Level 4 itself.

• Five lines, one per arc you choose, in the question|a|b|c|answer form.
• The split My Block and the 1-2-3 guard from Lesson 37.
• A wrong answer is told the right one.

Where next?

Scratch has taught you variables, lists, loops, My Blocks, clones and game maths. The same ideas carry on in the other Game Developer courses:

• Pygame — the same games in real Python code. Your vx and vy are exactly what it uses.
• Roblox Studio — 3D worlds, with scripts in Lua.
• Godot — a real game engine, the kind studios use.

The class credits

Every game in the showcase, rolling up the Stage like the end of a film.

• A list, one line per person and their game — made-up names or first names only.
• Each line glides from the bottom of the Stage to the top.

Summary 5 min

• A pitch is four beats: hook, demo, what you learnt, thanks — two minutes.
• A shuffle gives a fair order; nobody has to choose.
• Level 4 was twelve arcs: drawing, music, levels as data, physics, film, quizzes, queues — and sharing.
• A certificate, like a project, carries a first name at most.

Level 4 in one table

Hand in

Save your portfolio, your remix and your certificate. Next comes the Level 4 assessment — and then the next course you chose.
