Goal

"A goal is not always meant to be reached. Often it serves simply as something to aim at." — Bruce Lee

What Is It?

A Goal is a quest objective that drives the adventure forward. It defines what the player is trying to achieve and when they've succeeded (or failed).

Goals create narrative tension — the gap between current state and desired state.

Schema Mechanism Connection

From Gary Drescher's theory:

code

Context → Action → Result

Goals define the desired Result that motivates Action. The adventure is a laboratory for learning causal chains that achieve goals.

Goal Properties

Property	Purpose
`id`	Unique identifier
`name`	Short display name
`description`	What you're trying to achieve
`status`	pending, active, complete, failed
`complete_when`	Natural language condition
`fail_when`	When goal becomes impossible
`reward`	What you get on completion
`progress`	Partial completion tracking

Completion Conditions

Natural language conditions that compile to JS/PY:

yaml

complete_when: "player has the treasure"
complete_when_js: "(ctx) => ctx.player.inventory.includes('treasure')"

Rewards

Goals can grant various rewards:

yaml

reward:
  buff: "Hero's Glory"           # Temporary effect
  item: "champion-medal"         # Object
  unlock: "secret-room"          # New access
  narrative: "The kingdom celebrates!"  # Story beat

Progress Tracking

For multi-step goals:

yaml

progress:
  collected: 3
  needed: 5

Goal Hierarchies

Goals can nest:

yaml

parent: defeat-dragon
children:
  - find-magic-sword
  - learn-dragon-weakness
  - reach-dragon-lair

Complete all children to complete the parent.

Failure Conditions

Goals can fail:

yaml

fail_when: "time reaches midnight AND prisoner is not freed"
fail_message: "You were too late."

Examples

Simple Quest

yaml

goal:
  id: find-treasure
  name: "Find the Treasure"
  complete_when: "player has the treasure"

Timed Challenge

yaml

goal:
  id: rescue-mission
  name: "Save the Prisoner"
  complete_when: "prisoner is freed"
  fail_when: "10 turns pass without rescue"
  priority: urgent

Collection Quest

yaml

goal:
  id: gather-keys
  name: "Collect All Keys"
  complete_when: "player has 5 enchanted keys"
  progress:
    collected: 2
    needed: 5
