What i think is happening here is
Updating variable wont change the volume of already playing sound.
Details :
- Your sound begins to play with the default value, and wont dynamically change if you change
Music Volume - If you want sound to change, you must stop current sound, and play new one, with updated value.
Suggestion:
- Make your sound a
variable.(MainMenuSound of type
SoundCue) - Feed it to your play sound
2D - OnValueChanged, try setting a
new volume to your sound
variable (MainMenuSound)
