Overridden from ISaveGameSystem

  Type Name Description
Public function Virtual bool

DeleteGame ( bool bAttemptToUseUI,
const TCHAR* Name,
const int32 UserIndex
)

 Delete an existing save game, blocking until complete
Public function Virtual void

DeleteGameAsync ( bool bAttemptToUseUI,
const TCHAR* Name,
FPlatformUserId PlatformUserId,
FSaveGameAsyncOpCompleteCallback Callback
)

 Delete the named savegame asyncronously.
Public function Virtual bool

DoesSaveGameExist ( const TCHAR* Name,
const int32 UserIndex
)

 Return true if the named savegame exists (probably not useful with NativeUI
Public function Virtual void

DoesSaveGameExistAsync ( const TCHAR* Name,
FPlatformUserId PlatformUserId,
FSaveGameAsyncExistsCallback Callback
)

 Asyncronous save functions
Public function Virtual ESaveExistsResult

DoesSaveGameExistWithResult ( const TCHAR* Name,
const int32 UserIndex
)

 Syncronous save functions
Public function Virtual bool

GetSaveGameNames ( TArray< FString >& FoundSaves,
const int32 UserIndex
)

 Gets a list of all known saves. This isn't possible on all platforms.
Public function Virtual void Gets a list of all known saves if the platform supports it.
Public function Virtual bool

LoadGame ( bool bAttemptToUseUI,
const TCHAR* Name,
const int32 UserIndex,
TArray< uint8 >& Data
)

 Loads the game, blocking until complete
Public function Virtual void

LoadGameAsync ( bool bAttemptToUseUI,
const TCHAR* Name,
FPlatformUserId PlatformUserId,
FSaveGameAsyncLoadCompleteCallback Callback
)

 Load the named savegame asyncronously.
Public function Virtual bool

SaveGame ( bool bAttemptToUseUI,
const TCHAR* Name,
const int32 UserIndex,
const TArray< uint8 >& Data
)

 Saves the game, blocking until complete.
Public function Virtual void

SaveGameAsync ( bool bAttemptToUseUI,
const TCHAR* Name,
FPlatformUserId PlatformUserId,
TSharedRef< const TArray< uint8 >> Data,
FSaveGameAsyncOpCompleteCallback Callback
)

 Saves the named savegame asyncronously.
