In the Udon Graph and Udon Sharp there is currently no documentation. It would be convenient to have direct access to each function's documentation from Unity.
Here's an example from UdonSharp, with documentation from https://docs.vrchat.com/docs/player-audio inserted:
Current:
public void SetVoiceDistanceNear(float near) => VRCPlayerApi._SetVoiceDistanceNear(this, near);
Proposed:
/// <summary>
/// The near radius, in meters, where volume begins to fall off. It is strongly recommended to leave the Near value at zero for realism and effective spatialization for user voices.
/// </summary>
/// <param name="far">in Meters, Range 0 - 1,000,000</param>
public void SetVoiceDistanceFar(float far) => VRCPlayerApi._SetVoiceDistanceFar(this, far);
According to the contributors of UdonSharp they cannot add documentation to the libraries themselves (for technical reasons).
For completeness sake I've attached an example of what it might look like in the Udon Graph. Though perhaps that should be a separate post.
