If you and a Monster or other player are in the same room, you are at Range 0; you may use shticks with a Range value of 0 to battle them.

You may use shticks with a Range greater than 0 (often abbreviated "Range > 0") against a foe even while in the same room with that foe.

You NEVER make a Ranged Attack at a foe at Range 0.

And Sneak Attack isn't a Battle Shtick, so Flying doesn't interfere with it.
