Re: [ns] How to get a mobile node's current position

Hi, today I find we could use tcl script to get a node's position. codes like this: set n1 [$ns node] $ns set X_ 15.0 $ns set Y_ 15.0 $ns set Z_ 0.0 ... set x_pos [$n1 set X_] ... 'set x_pos [$n1 set X_]' this script could be used to get the x value of n1's starting
