majiayu000 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:
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:
complete_when: "player has the treasure"
complete_when_js: "(ctx) => ctx.player.inventory.includes('treasure')"
Rewards
Goals can grant various rewards:
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:
progress:
collected: 3
needed: 5
Goal Hierarchies
Goals can nest:
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:
fail_when: "time reaches midnight AND prisoner is not freed"
fail_message: "You were too late."
Examples
