 I will be able to implement it into my game. So here is my blank document class and my audio slider class! Thanks for the help!
WHAT I'VE TRIED
I attempted to create public variables in the document class for the sprite and the slider, then create a new sprite/slider once the document class runs. I thought that to be on the right track, but then it started looking like I was going to have to do that for almost all the variables in the audio slider class. I also thought...well why can't I just run Volume() in the Document Class? Still confusing me a little why that doesn't work, but it doesn't.

 WHAT I'VE judge 
 I undertake to create public variables in the text file class for the sprite and the slider, then make a new sprite / luger once the document class discharge. I intend that to be on the right track, but then it started looking like I was going to suffer to do that for almost all the variables in the audio luger class. I also thought... well why can't I just scat Volume () in the Document Class? Still confusing me a little why that doesn't work, but it doesn't.
