If by blox you mean a blocks in a 3d grid then theres a few
ways to handle that.
One weird way that comes to mind is this.
You have a white texture with a grey bit in the middle for
your shadow. And the texture is applied to a sprite that is
aligned to the box you are currently on. To make the shadow
move around on the box, you simply scroll the texture along
to fit the current position of the character on the box.
The main drawback with that would be the shadow only works
on one block at a time but with a bit of tinkering you
could set up two such shadows so it works on two boxes at a
time.... however that would still run into problems when
the character moves diagonally. but you could always just
have 4 shadows. That would solve everything.
Alternatively, there probably some sourcecode around for a
deformable shadow mesh that hugs the environment. I actually
remember running such a thing on my computer. I think it
was made by Norc. It was pretty cool actually. It was
probably on blitzcoder.
