Walking Function

[Moh200jo]

Hi guys
Are there any examples for walking to specific targets?
For example: the targets are 4 boxes; the avatar should walk to reach them and then stop for 1s in front box (4 stops).
I used viz.move (x, y, z, speed, target distance)
But the problem is in target distance; If targets are as follows:
10, 20, 30, 40 all theses distances are measure from 0 point and move function measures this from 0 point; the avatar can do just the first target correctly.
Any ideas for this?
Alternatively, is there function can do this?
Thanks
