I'm playing Minecraft on the Xbox, and the only way to identify current position is by looking at the map.
The X and Z co-ordinates are what they are, as you only take up one block in those dimensions. However, I'm unsure how to interpret the Y co-ordinate. Is it at my head or my feet?
I found this question, which answers a lot about Xbox maps, but not the Y in relation to my character.
This matters for the purpose of finding proper depth for optimal ore-hunting, plus it would be nice to know.
