Player Constants

export const PLAYER_CONSTANTS = {
  DEFAULT_HEALTH: 100,
  DEFAULT_MAX_HEALTH: 100,
  DEFAULT_STAMINA: 100,
  DEFAULT_MAX_STAMINA: 100,
  BASE_MOVEMENT_SPEED: 1.0,

Stamina Mechanics (Client-Side)

Stamina is calculated client-side in PlayerLocal.ts with the following rates:

// Base rates (per second)
staminaDrainPerSecond = 2;              // While running
staminaRegenWhileWalkingPerSecond = 2;  // While walking
staminaRegenPerSecond = 4;              // While idle

// Weight modifier (affects drain)
weightDrainModifier = 0.005;            // +0.5% drain per kg carried

// Agility modifier (affects regen)
agilityRegenModifier = 0.01;            // +1% regen per agility level

Drain Formula:

drainRate = staminaDrainPerSecond × (1 + totalWeight × 0.005)

Regen Formula:

regenRate = baseRegenRate × (1 + agilityLevel × 0.01)

Examples:

Weight	Agility	Running Drain	Idle Regen	Walking Regen
0 kg	1	2.0/sec	4.04/sec	2.02/sec
20 kg	1	2.2/sec	4.04/sec	2.02/sec
50 kg	50	2.5/sec	6.0/sec	3.0/sec
100 kg	99	3.0/sec	7.96/sec	3.98/sec

Weight is calculated server-side and synced to the client via PLAYER_WEIGHT_CHANGED events. This ensures stamina calculations use accurate, server-authoritative weight values.

  MAX_INVENTORY_SLOTS: 28,
  MAX_BANK_SLOTS: 480,
  MAX_STACK_SIZE: 1000,

  // Tick-based timing (OSRS-accurate)
  DEFAULT_SMELTING_TICKS: 4,          // 2.4 seconds per bar
  DEFAULT_SMITHING_TICKS: 4,          // 2.4 seconds per item
  TICK_DURATION_MS: 600,

  // Input validation limits
  MAX_QUANTITY: 10000,
  MIN_QUANTITY: 1,
  MAX_ITEM_ID_LENGTH: 64,

  // Messages
  MESSAGES: {
    ALREADY_SMELTING: "You are already smelting.",
    NO_ORES: "You don't have the ores to smelt anything.",
    LEVEL_TOO_LOW_SMELT: "You need level {level} Smithing to smelt that.",
    SMELT_SUCCESS: "You smelt a {item}.",
    IRON_SMELT_FAIL: "The ore is too impure and you fail to smelt it.",
    
    ALREADY_SMITHING: "You are already smithing.",
    NO_HAMMER: "You need a hammer to work the metal on this anvil.",
    NO_BARS: "You don't have the bars to smith anything.",
    LEVEL_TOO_LOW_SMITH: "You need level {level} Smithing to make that.",
    SMITH_SUCCESS: "You hammer the {metal} and make a {item}.",
  },
} as const;

Context Menu Colors

// From GameConstants.ts
export const CONTEXT_MENU_COLORS = {
  ITEM: "#ff9040",      // Orange - for items (OSRS-accurate)
  NPC: "#ffff00",       // Yellow - for NPCs and mobs
  OBJECT: "#00ffff",    // Cyan - for scenery/objects
  PLAYER: "#ffffff",    // White - for players
} as const;

All context menu handlers now use these centralized constants instead of hardcoded values. This ensures consistency across all interaction types.

---

Raycast Proxy Constants

// From interaction/constants.ts
export const RAYCAST_PROXY = {
  BASE_RADIUS: 0.4,         // Base radius for humanoid proxies (meters)
  BASE_HEIGHT: 1.2,         // Base height for humanoid proxies (meters)
  Y_OFFSET: 0.8,            // Y-offset to center proxy on entity body (meters)
  TALL_HEIGHT: 1.6,         // Height for taller mob proxies (meters)
  CAP_SEGMENTS: 4,          // Capsule geometry segments (radial)
  HEIGHT_SEGMENTS: 8,       // Capsule geometry segments (height)
} as const;

Performance: VRM SkinnedMesh raycast is extremely slow (~700-1800ms) because THREE.js must transform every vertex by bone weights. Invisible capsule proxies provide instant click detection.

Equipment Slots

export const EQUIPMENT_SLOTS = {
  WEAPON: "weapon",
  SHIELD: "shield",
  HELMET: "helmet",
  BODY: "body",
  LEGS: "legs",

} as const;
