scale

hi
is here someone who can tell me, what does it mean

in procedure :
MoveEntity entity,x#,y#,z#'

Parameters
entity - name of entity to be moved
x# - x amount that entity will be moved by

what does mean "amount" , example x=1, is that mean that entity will move 1 pixel ? 10 pixels or 100 pixels in my 3d world ?

thanks for answers
and sorry for my english i don't write well yet

Your 3D world is measured in 'Units'.

What are Units? Whatever you want them to be. A unit can be a centimetre, a metre, a mile... whatever.

Provided you establish what scale you're using at the start, and keep to it throughout, you won't get too many problems.

Yeah, if you're new to 3D, put the concept of moving stuff by pixels right to the back of your mind. :)

Actually we're talking about socalled Blitz-Units here. Some say you should per convention use a scale of one Blitzunit = one Meter in virtual space. Scale your Building in a way so eg. doors are about 1.2*2.5 Blitzunits or meters in size.
