UpdateSound

This update method is called on LateUpdate, but also on PlaySound. It handles adjusting the sound's volume and panStereo. This method only applies when sound is present and for anything except npcdata of MusicRange.

First, the panStero is adjusted if the sound is playing to the campos's x mapped lerped from -1.0 to 1.0 and then clamped to the proper side depending on the transform's actual x position. For example, if the entity is positioned relatively to the left of the camera, the clamp will be from -1 to 0, but from 0 to 1 if it was positioned more to the right and from -1 to 1 if both x exactly match. This essentially helps to account both the viewport position and the actual position to determine where to pan the sound.

Finally, the volume is adjusted. When unpaused, the new sound's volume is adjusted to soundvolume * the game's soundvolume or the pausemenu's svolume if the game is paused at the Settings or Key Bindings window.
