◆ LoadBank() [4/4]

AKSOUNDENGINE_API AKRESULT AK::SoundEngine::LoadBank	(	const char *	in_pszString,
		AkBankID &	out_bankID,
		AkBankType	in_bankType = `AkBankType_User`
	)

Loads a bank synchronously.
The bank name and type are passed to the Stream Manager. Refer to General Information for a discussion on using strings and IDs. A bank load request will be posted, and consumed by the Bank Manager thread. The function returns when the request has been completely processed.

Returns

The bank ID, which is obtained by hashing the bank name (see GetIDFromString()). You may use this ID with UnloadBank().

AK_Success: Load or unload successful.
AK_BankAlreadyLoaded: This bank is already loaded, nothing done.
AK_InsufficientMemory: Insufficient memory to store bank data.
AK_BankReadError: I/O error.
AK_WrongBankVersion: Invalid bank version: make sure the version of Wwise that you used to generate the SoundBanks matches that of the SDK you are currently using.
AK_InvalidFile: File specified could not be opened.
AK_NotInitialized if the sound engine was not correctly initialized
AK_InvalidParameter if some parameters are invalid, check the debug console
AK_InvalidBankType if the bank type parameter is out of range.
AK_Fail: Load or unload failed for any other reason. (Most likely small allocation failure)

Remarks

The initialization bank (Init.bnk) 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 sound engine internally calls GetIDFromString(in_pszString) to return the correct bank ID. Therefore, in_pszString should be the real name of the SoundBank (with or without the BNK extension - it is trimmed internally), not the name of the file (if you changed it), nor the full path of the file. The path should be resolved in your implementation of the Stream Manager, or in the Low-Level I/O module if you use the default Stream Manager's implementation.

Note: When Wwise Authoring is connected to the game in "Profile And Edit (Sync All)" mode, LoadBank will return AK_Success even if the file is not found. The Capture Log will still report the missing file. For example, this will be the case when SoundBanks were not generated. If this option is selected, you can work without SoundBanks as long as Wwise Authoring is connected. The Init.bnk is still required to initialize the sound engine properly.
