Daily Ha, I've Tricked You! It IS Daily Work Log!
-Finished up the basics of:
-Visibility
-Movement Volume
-Added bare-bones GUI elements for them
There are three speeds you can move at: Creeping, Walking, and Running:
-Creeping is the quietest, as you make no noise at all. It's the slowest, though.
-Walking is what you'd expect; Decent speed at a moderate volume.
-Running is also what you'd expect: High speed, but it's the loudest.
You can also hug walls and sidle along them. This reduces your visibility and makes you completely silent, but it's about as slow as Creeping.
The material of the flooring you're walking on also effects the noise you make. Some are louder than others.
As you can see, I've drawn a lot of inspiration from Thief for this stuff. 'Cause that was my first taste of game development, and it was
awesome.
The GUI thus far:

The sphere in the center is a light that's brightness is linked to your visibility: The more visible you are, the brighter it is (And vice-versa).
The rings are emitted in time with your steps, and their size is linked to the volume of said steps. The louder you are, the larger they get.
