Data: Yes2SDK.data

← Back to overview

PlayerPrefs-style typed key-value storage. Works before init via a yes2sdk_-prefixed localStorage fallback; on strategy binding any pre-init keys are migrated into the platform store.

data or player: which do I use? Use data for almost all saved state: settings, preferences, high scores, and game progress. It's synchronous, typed (int / float / string), and works on every platform: cloud-synced where the platform offers it, local otherwise. Reach for the player module only when you need account-tied features: the player's identity, connected players, or server-verifiable signed save data. On CrazyGames, Yandex, and YouTube the two modules share the same underlying store, so keep any given key in one module. Don't write the same key through both.

Persistence varies by platform. On Yandex and YouTube this is cloud-backed (synced to the player's account). On Poki and GameDistribution there is no storage API, so Data is emulated with localStorage: device-local, can be cleared by the browser, not synced across devices. CrazyGames uses its native data module.

Methods (Core)

Signature	Description
getInt(key, defaultValue?)	Get an int (default 0). key non-empty.
setInt(key, value)	Set an int. value must be a valid integer.
getFloat(key, defaultValue?)	Get a float (default 0).
setFloat(key, value)	Set a float.
getString(key, defaultValue?)	Get a string (default "").
setString(key, value)	Set a string.
hasKey(key)	Whether a key exists.
deleteKey(key)	Delete a single key.
deleteAll()	Delete all SDK keys.
setStringAsync(key, value): Promise<boolean>	Set + await confirmation. true on confirmed write, false on failure (e.g. quota).
setIntAsync(key, value): Promise<boolean>	Async confirmed int write.
setFloatAsync(key, value): Promise<boolean>	Async confirmed float write.

Platform support

The Data module is functional on every platform. The distinction is storage backing.

Capability	Poki	GameDistribution	CrazyGames	Yandex	YouTube
Read/write (getInt/setInt/…)	Partial	Partial	Ready	Ready	Ready
Backing store	localStorage	localStorage	CrazyGames native	Cloud (player.getData/setData)	Cloud (ytgame.game.load/saveData)
Cross-device sync	No	No	Yes	Yes	Yes

On the cloud platforms (Yandex, YouTube), synchronous setters are write-behind: they update an in-memory cache immediately and flush to the cloud on a debounce and on platform pause. The async setters (set*Async) await the cloud write and return success.

Unity (C#)

Yes2SDK.Data. Editor uses Unity PlayerPrefs; CrazyGames uses cloud storage; Poki uses localStorage.

Signature	Description
int GetInt(string key, int defaultValue = 0)
void SetInt(string key, int value)
float GetFloat(string key, float defaultValue = 0f)
void SetFloat(string key, float value)
string GetString(string key, string defaultValue = "")
void SetString(string key, string value)
bool HasKey(string key)
void DeleteKey(string key)
void DeleteAll()
