Extract the curve of a given type from the set of Attenuation curves attached to the given audio object. The curve's data is copied into an opaque data structure, pointed to by out_curve. The curve's data remain until the client of this service calls AK::IAkPluginServiceAttenuationCurve::Delete. - Returns
- true if the copy succeeded, or if the requested curve was not initialized.
- Parameters
-
| in_pAllocator | Memory allocator. |
| in_object | The audio object from which to extract the curve. |
| in_curveTypesMask | The set of curves, identified with a mask of bits offset by AkAttenuationCurveType values, to extract from the set of Attenuation curves. For example, set to (1 << AttenuationCurveID_VolumeDry | 1 << AttenuationCurveID_Spread) to obtain the distance-driven dry volume and spread curves. |
| out_curves | The returned addresses of the requested curve data. Pass in an array of void* with length corresponding to the number of desired curves. For each curve, if it exists, a blob of data is allocated by the function and the address is returned in the corresponding item of the out_curves. The item is set to nullptr if the curve does not exist. |
