Hi there!
Started working on audio volume sliders in our first game prototype, mAIn COMPetition. The game will allow you to set the volume levels for music (made by LizKatrinMusic) and, separately, the sound effects. All in real-time.
So far I'm building a prototype for this option (yeah, a prototype for a prototype!) and the work's going smoothly.
Cheers and have a great Sunday!
