rolloff_factor# (optional) - the rate at which volume diminishes with distance. Defaults to 1. doppler_scale# (optional) - the severity of the doppler effect. Defaults to 1. distance_scale# (optional) - artificially scales distances. Defaults to 1. |
| Creates a listener entity and returns its handle. Currently, only a single listener is supported. |
