Interface PlayerData

All Known Implementing Classes:

AndroidPlayerData, DesktopPlayerData, IOSPlayerData

public interface PlayerData

Common interface for reading/writing player data, e.g. game saves, preferences, etc. The location to save data in is automatically determined by the game identifier and the current platform. All files/directories specified by the developer will be automatically placed inside the pre-determined data location. Note: Objects must use Field annotations to be serialized/deserialized properly
