How to get a list of selected vertexes in order(+)

[ism]

of selection. By default, Maya gives it in order of increasing indexes.
Select vtx [5] [3] [15] [1]

Type ls -sl or filterExpand and MAYA gives
[1] [3] [5] [15]

It's critical in my case.

Thanks for help

You cant! Thats the point! Unless theres soemthin radicaly new in maya 4.5.

There is a hack workaround but its not for the faint hearthed. Undo, undo undo undo and looka at what is left each time around! (or could you perhaps read the undooo queue??!? anyone?!)

Someone could finaly make an api select in order tool so that this can be don nteligently ableit rough the tool but a smaal price to pay for such use!

I tried on both systems 4.0 and 4.5
btw, scriptContext gives vertexes in index order too (!!!)
Only one way i found - scriptJop which will look for selection type and start to write selection in array if it's vertex. But it's not funny

Yeah i know but its a bit...

Anyway alias has many tools that do this all the time but they havent managed to put a tool that could output this to any script!

But to be hnest making one in api isnt that hard mean make a tool that takes the array and returns it on enter (finish tool) to the mel. Now how hard is that!

Really check what Roger Klado came up with on his Claydough script. Was his issue too, he first went using a scriptJob, then we noticed it had some big performance hit on heavy models. In latest version seems he went for an alternate method that might be worth checkign for you.

I'd been thinking about this problem for a while, but this post gave me the idea, at last. I tried to whip up some code, it might be buggy though, and I haven't really tested it. Go ahead and try it!

global proc string [] sz_ReturnComponentSelectionInOrder () {

string $selectionAll[] = ls -sl;
int $counter = 0;
string $selection[];
string $realSelection[];
clear $selection;
string $buffer[];

for ($i = 0; $i < 100; $i++)
{
string $lastCommand = `undoInfo -q -un`;
if (`match "select" $lastCommand` != "")
{
tokenize $lastCommand " " $buffer;
$selection [$counter] = $buffer[2];
$counter++;
undo;
}
}
//print ($counter + " items in undo queuen");
select $selectionAll;

for ($i = 0; $i < `size $selection`; $i++)
$realSelection [(`size $selection`- $i)] = $selection[$i];

return $realSelection;
}

Yes that would probably work quite well!

I ran a quick test on a poly plane, and it worked perfectly!

Nice Job, arianrod!!!!!!

Actualy it was limited a bit, so I post a nicer version... Although the selections limitations are the same: there is no way to use selection undo while selecting the components. Otherwise it seems to be working.

/*
This script returns the selected components' name as a string array in the proper order of the selection.
Without using any scriptJobs. It only works when the selection happens exactly before the process is called.

global proc string [] sz_ReturnComponentSelectionInOrder () {

string $selectionAll[] = ls -sl;
string $selection[];
string $realSelection[];
string $buffer[];
string $lastCommand = undoInfo -q -un;
int $counter = 0;

while (match "select" $lastCommand != "")
{
$lastCommand = undoInfo -q -un;
if (match "select" $lastCommand != "")
{
tokenize $lastCommand " " $buffer;
$selection [$counter] = $buffer[2];
$counter++;
undo;
}
}
select $selectionAll;

for ($i = 0; $i < (`size $selection`); $i++)
$realSelection [$i] = $selection[(`size $selection` - $i)-1];

return $realSelection;
}

nice one! might have to rejig some old scripts.

Couldnt this actualy be expanded so that it could do with selection undos? by checking if its undone and removing from the que (this would probably inpact the performance a bit but )...?

By the way use at own risk is a good thing to have in all scripts comment line, but i myself think its implied. But anyway
