[ns] z-co-ordinate

[terence_tan@dso.org.sg]

Dear fellow ns-users,

Why is the z-coordinate always 0.0? 

I add in some code to mobilenode::distance() to display the value of x,y,z. 
Then, I set       $node_(1) set Z_ 100 in the tcl script
Then, I set       Z_ = 200; in the mobilenode constrctor.

After compile and run, the display code in mobilenode::distance() display 
"Z = 0.0"

Is there anywhere else in the ns2 where z-coordinate is being set to 0.0?

Pls help!

Thanks,
Terence
