Depth dot is basicly the 1 pixle the spite is located at, usualy between its feet (those that have feet). changing the depth dot changes where the sprite gets drawn, since the engine looks at that 1 pixle to locate the graphics frames. If depth que is -1( no change) graphics above on the Y-axis get drawn behind, those below get drawn on top.
Changing the depth que changes what gets drawn on top, just remember the engine looks at that 1 pixle first to locate the graphics frame, then layers it from there.
