How to get Attenuation property value via WAAPI given Sound object ID?

Question

Hi,

Is it possible to get the RadiusMax value from the Attenuation object via WAAPI given the Sound object ID?

How do I get the Attenuation or other object properties if I only have the object ID for the Sound or AudioSource object?

Thanks!

Using the ak.wwise.core.object.get, use the options to specify what to obtain.

In the return options, use:

• "@@Attenuation" on an actor-mixer hierarchy object, music object or bus object, to obtain the attenuation object id and name, taking into consideration the Override parent settings.
• "audioSource:maxRadiusAttenuation" on an actor-mixer hierarchy object, music object, bus object or event object, to obtain the max radius value for an object, and the attenuation object id
• "@RadiusMax" on an attenuation object to obtain the max radius property value.

Example, to obtain the Attenuation object from a Sound id or Source id:

 

Arguments:
{
    "from": {
        "id": [
            "{24979032-B170-43E3-A2E4-469E0193E2C3}"
        ]
    }
}
Options:
{
    "return": [
        "@@Attenuation"
    ]
}

Note that with 2019.1.0+, you can chain accessors:

{
    "return": [
        "@@Attenuation.@RadiusMax"
    ]
}

Which is very similar to:

{
    "return": [
        "audioSource:maxRadiusAttenuation"
    ]
}
