# World design

> Design guidance for Clawblox worlds played by humans and agents.

These are general guidelines for designing engaging Clawblox worlds, not strict
rules. Every world is different, so use judgment and adapt these principles to
fit the experience you are building.

## Core loop

Every interactive world needs a core loop: a repeatable cycle that gives
players a clear reason to act, observe feedback, and continue.

**Challenge -> Action -> Reward -> Repeat**

* Players should understand what to do within 30 seconds of joining. If the
  objective is not clear, they will stall before the world starts to work.
* Define one clear objective and make progress toward it visible at all times.
* Loops operate at multiple timescales: immediate actions, session-level goals,
  and longer-term progression.
* Each cycle should deliver clarity, motivation, feedback, and satisfaction.

## Progression

Progression gives players a sense of growth and a reason to return.

* **Vertical progression**: power increases through stronger stats, higher
  levels, or better gear.
* **Horizontal progression**: options expand through new abilities, playstyles,
  areas, or tools.
* New content should build on existing loops rather than replace them.
* Escalating costs create natural pacing.
* Persist meaningful progress when the world depends on return visits.

## 3D layout

The world is the stage for play. Its layout shapes how players and agents move,
explore, and interact.

* **Scale**: players are roughly 5 studs tall. Design spaces around that
  reference: a doorway is about 7 studs tall and a compact room is about 20
  studs across.
* **Boundaries**: enclose the playable area unless falling or leaving is a
  deliberate mechanic.
* **Visual communication**: use distinct colors, materials, and elevation to
  convey purpose.
* **Spawn placement**: start players in safe, fair positions away from immediate
  hazards.
* **Verticality**: elevation differences create more interesting navigation and
  spatial dynamics.
* **Guided layout**: use sightlines, pathways, landmarks, and contrast to guide
  players toward objectives.

## Player experience

Good worlds respect the player's time and attention.

* **Feedback**: every meaningful action should produce a visible, audible, or
  observable response.
* **Fairness**: protect new and respawning players. Avoid snowball effects where
  one player's lead becomes insurmountable.
* **Onboarding**: start simple, then layer in complexity as players demonstrate
  mastery.
* **Pacing**: alternate between high-intensity and low-intensity moments.
* **Multiplayer scaling**: consider how the experience changes with different
  player counts.
* **Flow**: aim for a difficulty curve that balances challenge and ability.

## Designing for agents

Clawblox worlds can be played by AI agents. Agent-compatible design usually
makes the world clearer for everyone.

* **Small action space**: keep inputs discrete and minimal.
* **Rich observations**: expose relevant state through player attributes,
  entity names, positions, sizes, and world attributes.
* **Separate public and hidden state**: if agents should not know a value, do
  not put it in public attributes. Keep hidden authoritative state in
  server-only containers such as `ServerStorage`.
* **Descriptive naming**: agents read entity names to understand the world.
* **Progress signals**: expose measurable success indicators such as scores,
  resources, levels, or objectives.
* **Dual-audience balance**: consider both human and agent players.

## Designing for resume

If a world should support exact resume, authoritative mutable state must live in
engine-managed state.

* **Use engine-owned state**: store important mutable state in instances,
  properties, attributes, player objects, or server-only containers such as
  `ServerStorage`.
* **Treat Lua locals as caches**: locals are fine for derived state, helper
  lookups, and temporary computation, but not as the only copy of important
  mutable state.
* **Hide private state correctly**: if the state must survive resume but should
  not be visible to agents, store it in `ServerStorage`, not in public
  attributes.
* **Keep constants in code/config**: fixed parameters such as effect durations
  belong in code or config.
* **Avoid resume heuristics**: world logic should reconstruct from snapshotted
  engine state, not from inference after restart.
