Data Manifests Overview

Manifest-Driven Design

Hyperscape uses a manifest-driven architecture where all game content (NPCs, items, world areas) is defined in external data files rather than hardcoded in logic. This separation enables:

Easy content updates — Edit JSON, restart server
Community modding — No code changes required
AI generation — Generate content with Asset Forge
Clean separation — Data vs logic isolation

All manifests are loaded from world/assets/manifests/ at runtime by the DataManager.

  MAX_NPCS_PER_ZONE: 10,
  SPAWN_RADIUS_CHECK: 5,          // Don't spawn if player within 5 meters
  AGGRO_LEVEL_THRESHOLD: 5,       // Some NPCs ignore players above this
} as const;

Items

Items are loaded from JSON into the ITEMS Map. Items are now organized into separate files by type for better organization:

// From packages/shared/src/data/items.ts
export const ITEMS: Map<string, Item> = new Map();

Item Types & Organization

Type	Description	File
`"weapon"`	Combat weapons	`items/weapons.json`
`"tool"`	Skilling tools	`items/tools.json`

`"currency"`	Coins	`items/misc.json`
`"junk"`	Burnt food, worthless items	`items/misc.json`
`"misc"`	Everything else	`items/misc.json`

Tier-Based Equipment

Items now use a centralized tier system defined in tier-requirements.json. Equipment references their tier (e.g., “bronze”, “steel”, “rune”) and the system looks up requirements automatically:

// Item with tier reference
{
  "id": "bronze_sword",
  "tier": "bronze",  // References tier-requirements.json
  // ... other properties
}

Supported Tiers:

Melee: bronze, iron, steel, black, mithril, adamant, rune, dragon
Tools: Same as melee (with different skill requirements)
Ranged: leather, studded, green_dhide, blue_dhide, red_dhide, black_dhide
Magic: wizard, mystic, infinity, ahrims

  "bronze_hatchet",
  "fishing_rod",
  "tinderbox",
  "arrows",
];

Bank Notes

The system supports bank notes for stackable versions of items:

// From packages/shared/src/data/items.ts
export const NOTE_SUFFIX = "_note";

// Check if item can be noted
canBeNoted(itemId: string): boolean

// Get noted variant
getNotedItem(itemId: string): Item | null

// Get base item from note
getBaseItem(itemId: string): Item | null

// Check if ID is a noted item
isNotedItemId(itemId: string): boolean

Drop Tables

NPCs have tiered drop tables:

interface DropTable {
  defaultDrop: {
    enabled: boolean;
    itemId: string;
    quantity: number;
  };
  always: Drop[];      // 100% chance
  common: Drop[];      // High chance
  uncommon: Drop[];    // Medium chance
  rare: Drop[];        // Low chance
  veryRare: Drop[];    // Very low chance
}

interface Drop {
  itemId: string;
  minQuantity: number;
  maxQuantity: number;
  chance: number;      // 0.0 - 1.0
}

Drop Calculation

// From packages/shared/src/data/npcs.ts
export function calculateNPCDrops(npcId: string): Array<{ itemId: string; quantity: number }> {
  const npc = getNPCById(npcId);
  const drops: Array<{ itemId: string; quantity: number }> = [];

  // Add default drop if enabled
  if (npc.drops.defaultDrop.enabled) {
    drops.push({
      itemId: npc.drops.defaultDrop.itemId,
      quantity: npc.drops.defaultDrop.quantity,
    });
  }

  // Process all tiers with RNG
  const processDrop = (drop: Drop) => {
    if (Math.random() < drop.chance) {
      const quantity = Math.floor(
        Math.random() * (drop.maxQuantity - drop.minQuantity + 1) + drop.minQuantity
      );
      drops.push({ itemId: drop.itemId, quantity });
    }
  };

  npc.drops.always.forEach(processDrop);
  npc.drops.common.forEach(processDrop);
  npc.drops.uncommon.forEach(processDrop);
  npc.drops.rare.forEach(processDrop);
  npc.drops.veryRare.forEach(processDrop);

  return drops;
}

World Areas

World areas define zones, biomes, and spawn points:

packages/shared/src/data/
├── world-areas.ts        # Zone definitions
└── world-structure.ts    # World layout

Zone Properties

Property	Description
`id`	Unique zone identifier
`name`	Display name
`biome`	Biome type (forest, plains, etc.)
`difficulty`	0-3 difficulty level
`mobs`	NPCs that spawn here
`resources`	Trees, fishing spots, etc.
`isSafe`	Whether it’s a safe zone

Banks & Stores

// From packages/shared/src/data/banks-stores.ts
// Defines bank locations and shop inventories

Each starter town has:

Bank — Item storage facility
General Store — Basic equipment vendor

Stations

Crafting stations are interactive objects that enable processing skills like smithing, smelting, and cooking:

interface StationData {
  type: string;           // "anvil" | "furnace" | "range" | "bank"
  name: string;           // Display name
  model: string;          // Path to 3D model
  modelScale: number;     // Scale multiplier
  modelYOffset: number;   // Vertical offset
  examine: string;        // Examine text
}

Available Stations

Station	Purpose	Model	Scale	Y Offset
Anvil	Smith bars into equipment	`asset://models/anvil/anvil.glb`	0.5	0.2
Furnace	Smelt ores into bars	`asset://models/furnace/furnace.glb`	1.5	1.0
Range	Cook food with reduced burn chance	`asset://models/cooking-range/cooking-range.glb`	1.0	0.3
Bank	Store items	`asset://models/bank-chest/bank-chest.glb`	0.5	0.10
Altar	Restore prayer points	`asset://models/prayer-alter/prayer-alter.glb`	1.0	0.25

Station entities (Altar, Bank, Range) now load 3D models from the manifest system with automatic fallback to placeholder geometry if models are unavailable.

Station Model Loading

Station entities load 3D models from the manifest system using StationDataProvider:

// AltarEntity.ts, BankEntity.ts, RangeEntity.ts
const stationData = stationDataProvider.getStationData("altar");
const modelPath = stationData?.model ?? null;
const modelScale = stationData?.modelScale ?? 1.0;
const modelYOffset = stationData?.modelYOffset ?? 0;

// Try to load 3D model first
if (modelPath && this.world.loader) {
  try {
    const { scene } = await modelCache.loadModel(modelPath, this.world);
    
    this.mesh = scene;
    this.mesh.name = `Altar_${this.id}`;
    
    // Scale the model from manifest
    this.mesh.scale.set(modelScale, modelScale, modelScale);
    
    // Offset Y position so model base sits on ground
    this.mesh.position.y = modelYOffset;
    
    // Enable shadows and set layer for raycasting
    this.mesh.layers.set(1);
    this.mesh.traverse((child) => {
      child.layers.set(1);
      if (child instanceof THREE.Mesh) {
        child.castShadow = true;
        child.receiveShadow = true;
      }
    });
    
    return;
  } catch (error) {
    console.warn(`[AltarEntity] Failed to load altar model, using placeholder:`, error);
  }
}

// FALLBACK: Create placeholder geometry
const geometry = new THREE.BoxGeometry(0.9, 0.8, 0.9);
const material = new THREE.MeshStandardMaterial({
  color: 0x9932cc, // Purple for altar
  roughness: 0.5,
  metalness: 0.3,
});

Fallback Colors:

Altar: Purple (0x9932cc)
Bank: Black (0x111111)
Range: Red (0xcc3333)

All fallback materials now use MeshStandardMaterial for consistent lighting behavior.

Crafting Stations

Stations are defined in stations.json:

Anvil - Used for smithing bars into equipment
Furnace - Used for smelting ores into bars
Range - Used for cooking food (reduces burn chance compared to fires)
Bank Booth - Used for accessing bank storage

Each station defines its 3D model, scale, position offset, and examine text. Range Entity: The range is a permanent cooking station that provides better burn rates than fires. Players can use raw food on ranges just like fires, but with reduced burn chance. Ranges are placed in starter towns and other settlements.

// RangeEntity extends InteractableEntity
// Location: packages/shared/src/entities/world/RangeEntity.ts
// Supports cooking with reduced burn rates per cooking.json stopBurnLevel.range

Tool Metadata

The tools.json manifest defines tool-specific properties:

Skill - Which skill the tool is used for
Tier - Tool tier (bronze, iron, steel, etc.)
Priority - Tool selection priority (higher = better)
Roll Ticks - For mining pickaxes, ticks between roll attempts

This metadata is separate from item definitions to keep tool mechanics centralized.

Skill Progression

Crafting Stations

Stations are defined in stations.json and represent interactive objects in the world used for processing skills:

interface Station {
  type: string;           // "anvil" | "furnace" | "range" | "bank"
  name: string;           // Display name
  model: string | null;   // Path to 3D model
  modelScale: number;     // Model scale multiplier
  modelYOffset: number;   // Vertical position offset
  examine: string;        // Examine text
}

Available Stations

Station	Purpose	Model	Scale	Y Offset
Anvil	Smithing bars into equipment	`models/anvil/anvil.glb`	0.5	0.2
Furnace	Smelting ores into bars	`models/furnace/furnace.glb`	1.5	1.0
Cooking Range	Cooking food (reduced burn chance)	`models/cooking-range/cooking-range.glb`	1.0	0.5
Bank Chest	Accessing bank storage	`models/bank-chest/bank-chest.glb`	0.5	0.75
Altar	Restoring prayer points	`models/prayer-alter/prayer-alter.glb`	1.0	0.25

Stations are placed in world areas and interact with the corresponding recipe manifests (recipes/smithing.json, recipes/smelting.json, etc.).

Tool Metadata

The tools.json manifest defines tool-specific properties separate from item definitions:

interface ToolMetadata {
  itemId: string;         // References items/tools.json
  skill: string;          // "woodcutting" | "mining" | "fishing"
  tier: string;           // Tool tier
  levelRequired: number;  // Minimum skill level
  priority: number;       // Tool selection priority (higher = better)
  rollTicks?: number;     // Mining only: ticks between roll attempts
}

Tool Priority System

When multiple tools are available, the system selects the highest priority tool: Woodcutting Hatchets:

Tool	Priority
Crystal	1 (best)
Dragon	2
Rune	3
Adamant	4
Mithril	5
Steel	6
Iron	7
Bronze	8 (worst)

Mining Pickaxes (also includes rollTicks for mining speed):

Tool	Priority	Roll Ticks
Crystal	1	3
Dragon	2	3
Rune	3	3
Adamant	4	4
Mithril	5	5
Steel	6	6
Iron	7	7
Bronze	8	8

Vegetation & Biomes

Vegetation Assets

The vegetation.json manifest defines procedural vegetation assets for world generation:

interface VegetationAsset {
  id: string;                       // Unique asset ID
  model: string;                    // Path to GLB model

interface VegetationLayer {
  category: string;           // Matches vegetation.json categories
  density: number;            // Spawn density
  assets: string[];           // Asset IDs (empty = all in category)

Runecrafting Recipes

The recipes/runecrafting.json manifest defines rune crafting at altars:

interface RunecraftingRecipe {
  runeType: string;            // Rune type identifier
  runeItemId: string;          // Output rune item ID
  levelRequired: number;       // Runecrafting level required
  xpPerEssence: number;        // XP per essence used
  essenceTypes: string[];      // Accepted essence types
  multiRuneLevels: number[];   // Levels for multiple runes per essence
}

Rune Types:

Air (level 1, 5.0 XP) - Accepts rune essence or pure essence
Mind (level 2, 5.5 XP) - Accepts rune essence or pure essence
Water (level 5, 6.0 XP) - Accepts rune essence or pure essence

Adding New Content

Choose the right manifest

Items: Add to appropriate file in items/ directory
Gathering: Add to gathering/woodcutting.json, mining.json, or fishing.json
Recipes: Add to appropriate file in recipes/ directory
NPCs: Add to npcs.json

Follow existing patterns

Use the same structure as existing entries. For tiered equipment, specify the tier field.

Generate 3D model (optional)

Use Asset Forge to create a new model, or use existing models

Restart server

The DataManager loads manifests on startup

Test in game

Verify the new content appears correctly

Do NOT add game data directly to TypeScript files. Keep all content in JSON manifests for clean separation and easy modding.

Recipe system: New recipes directory for smelting, smithing, cooking, firemaking, fletching, crafting, and runecrafting
Centralized requirements: tier-requirements.json provides OSRS-accurate level requirements
Skill unlocks: skill-unlocks.json documents progression milestones

New Vegetation (PR #4)

Mushroom vegetation added to biomes with configurable density, clustering, and spawn parameters.
