How to make a sound louder the closer you get to the source and fade out the further you are away

So I have a chimney in my 2d game. I want it so that when the player is really close to it the steam spray will be loud and once walking away it will fade out. I have a script where the sound plays once you get in distance but shuts off as soon as you're out of range. The change is too abrupt. Please Help

 

Hi Markeus,

Good news ! What you're trying to do already exists in Unity and is the basis of what Unity calls 3D sound. It means spatialized sound : distance, volume rolloff (what you call fade out), reverb usage, doppler and more are already there. Be careful not to confuse 3D sound with a 3D game : absolutely no link.

I already answered something similar here, see if it helps.

1) I'd remmond placing an AudioSource on the chimney object and tweaking it to your liking (especially the "spatialize" slider, which decides whether the sound will be spatialized by Unity or not). Do that in the editor, not by scripting, the editor's there for exactly that purpose : making your life easier and visual.

2) Then arises the question of the AudioListener... If the camera follows the character, and depending on its actual position in the 3D space of the scene view, everything could be alright if you put, like always, an AudioListener on the camera.

3) If this does not work like expected, tweak the AudioSource a bit more (especialy the max distance, I'd say).

4) If the damned chimney is still wrong, you should go for a modified AudioLister : make it follow the character, while keeping the rotation coordinates equal to the ones of the camera.

Hope this helps,

Edit : you won't need the TriggerEnter and other boxes anymore : the audiosource manages its own "zone"
