Not sure which version you're playing, but currently when you're low on food you get your avatar grunting every 3 seconds as though someone's clubbing him over the head and the view skews off to one side as though someone's clubbing him over the head. :C
This may be down to the regeneration - you lose some health due to hunger, then goes back up again, not sure if it still does that at half health. :?
That's fine, but the health on Teh Server auto regenerates - so you lose half a heart to hunger when the food bar reaches 0, and then immediately regenerates, so never actually gets to the half way mark where it stops dropping.
'Cos of the regeneration you constantly keep losing half a heart along with the grunting sound and annoying screen tilt that happens when you take damage.
:C
But... :-|
I don't want to.
There's a whole argument here about the pros and cons of creator/adventuring modes and whether having to eat in a game isn't all that different really to acquiring new armour/clothes etc. But I'm in a good mood, what with Christmas fast approaching, so don't really care. :-{)
