The skill

Games are bad at telling stories and extraordinary at implying them.

A cutscene explaining that the station was evacuated in a hurry is fine. A half-eaten meal, a child's drawing pinned to a locker, and one door welded shut from the inside is better — because the player assembled it themselves, and people believe what they figure out far more than what they are told.

That's environmental storytelling: putting information in objects and space rather than in sentences.

Today you build one room that tells a story, with a hard limit on how many words you may use.

By the end of the block you will have: a room a stranger can walk into and describe what happened there — using fewer than 60 words of text.


What you need


Part 1 — Write the premise, then hide it (10 min)

1. One sentence

Write what happened in this room. One sentence. Past tense.

Someone lived here alone for a long time and left in a hurry.
Two people worked here, and one of them stopped coming.
This was a safe place until the thing outside got in.

2. Break it into three facts

List the three facts a player would need to reconstruct that sentence.

For "two people worked here, and one stopped coming":

  1. Two people worked here.
  2. Time passed.
  3. Only one of them is still using the space.

3. Assign each fact an object — not a sentence

This is the whole exercise.

Fact ❌ Told ✅ Shown
Two people worked here "We shared this workshop." Two chairs, two mugs, two sets of tools
Time passed "It's been months." Dust on one chair. A calendar stopped on one date
One stopped coming "I don't know what happened to her." One mug still where it was left; the other washed and stacked

Write your version of this table before you build anything. It is the graded artifact.

✅ Checkpoint 1 — a one-sentence premise, three facts, and an object assigned to each.


Part 2 — Build the room (25 min)

4. Make the space

A small enclosed area — four walls and a floor is plenty. Use your Ex 5 tilemap or plain sprites.

Small. One room. The temptation is to build a facility; resist it. Density of meaning beats square footage every time.

5. Place your three objects

Greybox shapes are fine — a labelled cube reads as "a thing that matters" perfectly well at this stage.

Placement carries meaning, so use it:

Technique What it does
Composition Put the important object where the player is already looking when they enter
Repetition Two of something reads as a pair; three reads as a system
Disturbance One object out of alignment in an ordered room draws the eye instantly
Blocking Something in the way makes the player look at it

6. Add the props that aren't facts

Three or four objects that carry no information. A room containing only meaningful objects reads as a puzzle, not a place — the noise is what makes the signal feel discovered rather than presented.

✅ Checkpoint 2 — a room with three meaningful objects and some deliberate noise.


Part 3 — Add the words, sparingly (20 min)

7. Set up the dialogue

Add the DialogueTrigger helper to an empty GameObject with a trigger collider, or to an object with an Interactable.

Field Set to
beats Your text lines, one per element
advanceMode OnInput for examine-style beats, Timed for ambient ones
displayDuration 3 seconds is about right for one short line
playOnce ✔
showDebugText ✔ (your temporary UI until Ex 7)

Use Interactable + Interactor for anything the player chooses to examine. Text the player asked for is welcome; text that arrives uninvited is an interruption.

8. Write no more than 60 words, total

Across the entire room. Count them.

This limit is the exercise. With unlimited words you will explain the room, and explaining is what you are learning not to do. With 60 you have to let the objects work.

Good uses of your word budget:

Bad uses:

9. Optional — one scripted moment

If you have time: a Timeline that plays when the player enters. A light flickering, a door closing, a sound in another room. One is atmospheric; three is a haunted house.

✅ Checkpoint 3 — under 60 words total, delivered through triggers or interactables.


Part 4 — The stranger test (10 min)

10. Have someone else play it

Get the person next to you. Say nothing. Let them walk through, then ask one question:

"What happened in this room?"

Do not prompt. Do not explain. Write down exactly what they say.

11. Compare against your premise

Three possible outcomes, all useful:

They said It means
Roughly your sentence It works. Note which object they mentioned first — that one is carrying the room.
A different but coherent story Often better than yours. Consider keeping theirs.
"I don't know" Your facts are too subtle, or drowned in noise. Make one object bigger, closer, or lit.

12. Write your notes

Docs/Ex06_notes.txt:

Premise: Two people worked here, and one of them stopped coming.

Fact 1: two people worked here -> two chairs, two mugs, two toolsets
Fact 2: time passed            -> dust sheet on one chair, calendar stopped
Fact 3: one stopped coming     -> one mug still out, the other stacked

Word count: 41

Tester said: "Someone died and their friend can't clear their desk."

What that told me: they got the relationship and the absence but read
it as death rather than just leaving, because I put a folded jacket on
the chair and that reads as a memorial. I kept it — their version is
sadder and more specific than mine, and the room supports it.

Which object did the most: the two mugs. Every tester mentioned them
first. The calendar did nothing — nobody looked up.

✅ Checkpoint 4 — one stranger tested, their exact words recorded, and what you learned.


Part 5 — Build and submit (5 min)

13. Build into MyGameName/PC_Builds/Ex06/, then submit

Zip as lastname_ex06.zip: the build, your fact/object table, and Docs/Ex06_notes.txt.

Canvas → Assignments → Exercise 6.


Rubric — 2 points

Criterion Pt Met when
Implementation 1 Build runs · a walkable room with three meaningful objects · text delivered via DialogueTrigger or Interactable · under 60 words total · no console errors
Design decision 1 Fact/object table submitted · one stranger tested with their exact words recorded · notes state which object carried the room and what you changed or kept as a result

Troubleshooting

The dialogue fires the moment I press Play.
The trigger overlaps the player's start position. Move it.

Text appears and vanishes instantly.
displayDuration is very low, or advanceMode is OnInput and something is calling Advance() every frame.

The dialogue only plays once and I need to retest.
playOnce ✔ is doing its job. Untick it while iterating, then tick it again before you build.

Interactable doesn't prompt.
The player needs an Interactor component, and your object needs a Collider2D within interactRange. Select the player and check the white gizmo sphere actually reaches the object.

Nobody notices my most important object.
Almost always placement, not size. Put it where the player is looking when they enter, or put it in their path.
