need help simple script

yes, Max auto-sort them so just collect your wanted vertex separately.

hi Anubis,

Perhaps for Objects Max keep right order, but if you take a look to the .png, you will see that if I select vertex #5 then vertex #7 or in reverse order, resulting array is the same : [5,7] :-(((

Then the problem is about selection order. Max always return correct order, ie if there is some array: "sel=#(3,5,8)" then sel[1] will be 3, right? But are there sel[1] is the value that we need?... For more clear - to say 5 boxes in the scene and we wont to collect them:

sel = for b in $box* collect b.name
#("Box04", "Box05", "Box06", "Box02", "Box01", "Box03")

-- second line is result, as you see sel[1] will return "Box04" not "Box01". In Max available "sort" fn:

sort sel
#("Box01", "Box02", "Box03", "Box04", "Box05", "Box06")

-- well, now sel[1] will be "Box01". So in your case you must to decide how to collect align vertex.

hello
Thanks for help,
But in fact after testing, I saw that "selectedVert[1]" is not the first selected vertex but the first vertex in the array which 3dsMax reorder in growing order....

How can I tell Max to return me the first selected vertex ?

Okay, another hint - on FOR loop you start count from 1 that mean you include 1st vertex also, so the script will try to align 1st vertex to itself. Try to exclude it form the loop startin count by 2 like:

for loopVerts = 2 to selectedVert.count do

With this code, if the Array is #(1,3,7), the variable loopVerts will go from 1 to 3, because the arraycount is 3:

for loopVerts = 1 to selectedVert.count do

But you want to go through each item of the array, with this code loopVerts will be 1, 3 and 7:

for loopVerts in selectedVert do

yes, Anubis.
In fact I have 3 shortcut keys : one for x, one for y and one for z. This script is for z align.
But this script don't always align selected vertexes to the first selected vertex,and I don't understand why,.... :-((

I see so only Z axis affected
