Best Way to create a volume system for my game.

[@KB_United]

I currently tried creating a volume system using the sound_volume function and inputing a variable into that function that could be changed by the up or down keys via the player. When the player pressed the up or down keys it would subtract or add to the variable. That did not seem to work for some reason. So if anyone could help me out a little bit it would be greatly apreaciated.

audio_set_master_gain should be what you are looking for, would need more information if you want seperate sound , voice, and music sliders.
