setAttenuationModel method

FutureOr<int> setAttenuationModel(
  1. AttenuationType type,
  2. float coefficient
)

@detail api @author huangshouqin @brief Set the volume roll-off mode that a 3D sound has in an audio source when using the Range Audio feature. @param type Volume roll-off mode. It is linear roll-off mode by default. Refer to AttenuationType{@link #AttenuationType} for more details. @param coefficient Coefficient for the exponential roll-off mode. The default value is 1. It ranges 0.1,100. We recommended to set it to 50. The volume roll-off speed gets faster as this value increases. @return Result of the call
- 0: Success - -1: Failure because of calling this API before the user has joined a room or before enabling the Range Audio feature by calling enableRangeAudio{@link #IRangeAudio#enableRangeAudio}. @note Call updateReceiveRange{@link #IRangeAudio#updateReceiveRange} to set the range outside which the volume of the sound does not attenuate.

Implementation

FutureOr<int> setAttenuationModel(
    AttenuationType type, float coefficient) async {
  return await nativeCall('setAttenuationModel', [type.$value, coefficient]);
}
