Soundmanager

How to use: 

dezip the files and put the trigger and the soundmanager script in unity now atach the sound manager script on an empty GameObject here you setup the sounds please dont forget that the name is important and you can just refrence this script in another script and just  type this in this other script: SoundManager.Play(NameOfYourSound);

if you want a trigger that triggers a sound you just create another empty gameObject ,atach the trigger script to it and atach any collider on it resize the collider and put it on trigger in the name of sound you put the exact same name as the sound in the soundmanager script (The Player or whatever should trigger the collider needs to have the tag Player).
