◆ LoadBank() [8/8]

AKRESULT __cdecl AK::SoundEngine::LoadBank ( const void *  in_pInMemoryBankPtr,
AkUInt32  in_uInMemoryBankSize,
AkBankCallbackFunc  in_pfnBankCallback,
void *  in_pCookie,
AkMemPoolId  in_uPoolForBankMedia,
AkBankID out_bankID 

Loads a bank asynchronously (from in-memory data, out-of-place).
NOTE: Banks loaded from in-memory with out-of-place data must be unloaded using the standard UnloadBank function (with no memory pointer). Make sure you are using the correct UnloadBank(...) overload

Use this overload when you want to manage I/O on your side. Load the bank file in a buffer and pass its address to the sound engine, the media section of the bank will be copied into the specified memory pool.

In-memory loading is out-of-place: the buffer can be released after the callback function is called. The advantage of using this over the in-place version is that there is no duplication of bank structures. A bank load request will be posted to the Bank Manager consumer thread. The function returns immediately.

AK_Success if the scheduling was successful, AK_Fail otherwise, or AK_InvalidParameter if memory alignment is not correct. Use a callback to be notified when completed, and get the status of the request. The bank ID, which is obtained by hashing the bank name (see GetIDFromString()). You may use this ID with UnloadBank().
  • The initialization bank must be loaded first.
  • All SoundBanks subsequently loaded must come from the same Wwise project as the initialization bank. If you need to load SoundBanks from a different project, you must first unload ALL banks, including the initialization bank, then load the initialization bank from the other project, and finally load banks from that project.
  • Codecs and plug-ins must be registered before loading banks that use them.
  • Loading a bank referencing an unregistered plug-in or codec will result in a load bank success, but the plug-ins will not be used. More specifically, playing a sound that uses an unregistered effect plug-in will result in audio playback without applying the said effect. If an unregistered source plug-in is used by an event's audio objects, posting the event will fail.
  • The memory must be aligned on platform-specific AK_BANK_PLATFORM_DATA_ALIGNMENT bytes (see AkTypes.h).
  • (XboxOne only): If the bank may contain XMA in memory data, the memory must be allocated using the Physical memory allocator.
  • Requesting to load a bank in a different memory pool than where the bank was previously loaded must be done only after receiving confirmation by the callback that the bank was completely unloaded or by using synchronous versions of the UnloadBank function.
