Choose key-value storage or object storage based on the data shape. Your game must manage data versions, migration, overwrites, and cleanup; uploading a new build does not automatically delete existing data.

#TT.PlayerPrefs

Provides key-value storage for int, float, and string values. Call Save() after writing or deleting data to persist the changes.

#SetInt

Signature

public void SetInt(string key, int value)

Parameters

Example

TT.PlayerPrefs.SetInt("level", 5);

#GetInt

Signature

public int GetInt(string key, int defaultValue)

Return value

Returns the saved integer when the key exists; otherwise, returns defaultValue.

Example

int level = TT.PlayerPrefs.GetInt("level", 1);

#SetFloat

Signature

public void SetFloat(string key, float value)

Example

TT.PlayerPrefs.SetFloat("music_volume", 0.8f);

#GetFloat

Signature

public float GetFloat(string key, float defaultValue)

Return value

Returns the saved floating-point value when the key exists; otherwise, returns defaultValue.

Example

float volume = TT.PlayerPrefs.GetFloat("music_volume", 1.0f);

#SetString

Signature

public void SetString(string key, string value)

Example

TT.PlayerPrefs.SetString("player_name", "Alex");

#GetString

Signature

public string GetString(string key, string defaultValue)

Return value

Returns the saved string when the key exists; otherwise, returns defaultValue.

Example

string playerName = TT.PlayerPrefs.GetString("player_name", string.Empty);

#HasKey

Checks whether a specified key exists.

Signature

public bool HasKey(string key)

Return value

Returns true when the key exists; otherwise, returns false.

Example

bool exists = TT.PlayerPrefs.HasKey("player_name");

#DeleteKey

Deletes the specified key. Call Save() afterward to persist the change.

Signature

public void DeleteKey(string key)

Example

TT.PlayerPrefs.DeleteKey("player_name");
TT.PlayerPrefs.Save();

#DeleteAll

Deletes all key-value data stored through TT.PlayerPrefs.

Signature

public void DeleteAll()

Example

TT.PlayerPrefs.DeleteAll();
TT.PlayerPrefs.Save();

DeleteAll removes all key-value data. Call it only in explicit flows such as resetting local data.

#Save

Persists the current TT.PlayerPrefs changes.

Signature

public void Save()

Example

TT.PlayerPrefs.SetInt("level", 5);
TT.PlayerPrefs.Save();

#TT.Save(serializableObject, saveName)

Saves a serializable object under a specified name.

Signature

public static bool Save<T>(T serializableObject, string saveName)

Parameters

Return value

Returns true when the object is saved successfully; otherwise, returns false.

Example

bool saved = TT.Save(
    new PlayerSave { level = 5, coins = 120 },
    "player_save"
);

#TT.LoadSaving(saveName)

Loads a saved object by name. The generic type must match the data structure used when the object was saved.

Signature

public static T LoadSaving<T>(string saveName)

Return value

Returns the deserialized object.

Example

PlayerSave save = TT.LoadSaving<PlayerSave>("player_save");

#TT.DeleteSaving(saveName)

Deletes the object save with the specified name.

Signature

public static void DeleteSaving(string saveName)

Example

TT.DeleteSaving("player_save");

#TT.ClearAllSavings()

Deletes all data saved through the object-storage APIs.

Signature

public static void ClearAllSavings()

Example

TT.ClearAllSavings();

ClearAllSavings deletes all object saves. Confirm that the game no longer needs the data before calling it.

#TT.GetSavingDiskSize()

Reads the storage space currently used by object saves.

Signature

public static long GetSavingDiskSize()

Return value

Returns the number of bytes used by object saves.

Example

long bytes = TT.GetSavingDiskSize();
Debug.Log($"Saving size: {bytes} bytes");

Object type example

using System;

[Serializable]
public class PlayerSave
{
    public int level;
    public int coins;
}
