So I have an options menu set up and placed a slider to be able to adjust the music and sfx in game. Now the thing is…I have no clue where to start. All I think I know is to use sound classes and sound mix. I asked in the forums and so far no answer, I have been looking for a tutorial all day and all the ones I find, information is left out or something because I haven’t been able to get anything to work. I did find one tutorial that was able to change the music volume in one level but I need it to change the music for everything, plus every time the options menu was opened the BGM would start over and overlap.

Any good tutorial with good explanations would be greatly appreciated since this will be the first time doing this.

Well, you just need a global variable saved in a GameSave(that way it will be saved even if you left the game) with be stored in a GameSesion(that way you won’t lose it when you go to another level), with should multiply by the volume of each of your music. Pretty simple, good luck.

I found a channel that explained everything on how to do this and works perfectly! After looking forever. If anyone else is having trouble with this, here is the link to the channel, he has multiple videos with good info.
