Player profile + wallets — client.player

PlayerDomain (source: src/domains/PlayerDomain.ts) — the observable player profile: identity plus currency wallets. Synced under revision key profile.

There is no separate wallet service in this SDK. Wallet balances are read from the profile and are credited/debited server-side (purchases, quest/battle pass rewards, scenario nodes).

Surface

client.player is a SyncedState<PlayerProfile>:

client.player.data       // PlayerProfile | undefined
client.player.status     // 'idle' | 'loading' | 'ready' | 'error'
client.player.onChange((snapshot) => { /* fires immediately */ });
await client.player.load();
await client.player.reload();  // force refetch

Types

interface PlayerProfile {
  identities?: PlayerProfileIdentity[];
  player?: Player;
  wallets?: Wallet[];
}

interface PlayerProfileIdentity {
  createdAt: string;
  provider: string;  // 'device' | 'google' | 'apple' | 'custom' | 'custom:<name>'
  subject: string;
}

interface Player {
  createdAt?: string;
  id?: string;
  language?: string;
  nickname?: string;
  projectId?: string;
  region?: string;
}

interface Wallet {
  balance?: number;
  currency?: string;  // currency code configured in the dashboard
}

Behavior notes

• Warmed automatically at login (one of the four parallel warm loads).
• Invalidated (refetched) after every successful store purchase and after scenario server callbacks — subscribers see fresh balances without waiting for the revision poll.
• All fields are optional on the wire (?); code defensively.
• React: useSyncExternalStore maps directly onto onChange (see the SDK README "React recipe").
