Wwise SDK 2018.1.11

Posts an Event to the sound engine (by Event name), using callbacks. The callback function can be used to be noticed when markers are reached or when the event is finished. An array of Wave file sources can be provided to resolve External Sources triggered by the event. P

Returns

The playing ID of the event launched, or AK_INVALID_PLAYING_ID if posting the event failed

Remarks

If used, the array of external sources should contain the information for each external source triggered by the event. When triggering an Event with multiple external sources, you need to differentiate each source by using the cookie property in the External Source in the Wwise project and in AkExternalSourceInfo.

Note: If an event triggers the playback of more than one external source, they must be named uniquely in the project (therefore have a unique cookie) in order to tell them apart when filling the AkExternalSourceInfo structures.
