Volume

Turning sounds up and down with setVolume() and changeVolume().

Press space to play a sound, and the up and down arrow keys to change how loud it is. The volume is a percentage, as in Scratch, and stays between 0 and 100 however far you push it.

this.addSound("handleCoins");
this.setVolume(100);
...
this.changeVolume(-10);

The sound is one of the built-in sounds, so there is no file to find first.
