Using "Global String" ?

[mhovland]

global string $CurSel[];
global string $sproxy[];

$CurSel[] = `ls -sl`;
$sproxy[] = `polyDuplicateAndConnect $CurSel[0] `;

Declare the variables as global first, then populate them. Also remember to add the global declarations to the start of any procedure that needs to access them.

Be careful what you name them though, as global variables will be global through ALL of Maya and all other scripts. ou just want to avoid name clashes.

Hi

Thanks.
But I have some problems.

I want to call $base in other procs. I can't do this because
I have so many string (one within the other) inside my procedures. I confused :) :( .
Do you have an scripted example ?.

Thats mine :

global proc spsbs_c()
{
//Selection Control
string $CurSel[] = `filterExpand -sm 12`;
if(`size($CurSel)` == 0)

error "No polygon object selected.\n";

else
{
if(`size($CurSel)` > 1)
error "Please select only one polygon object.\n";
else
{

//Define selection and duplicate with connection
string $CurSel[] = `ls -sl`;
string $sproxy[] = `polyDuplicateAndConnect $CurSel[0] `;
polySmooth -dv 2 -kb 0 $sproxy[0];


//Operation BaseObject
string $base = $CurSel[0];
select $base;
createDisplayLayer -name "BaseObject_L";
setAttr ($base+ ".primaryVisibility") 0;

//Rename SmoothObject
string $proxy = $proxy = ` rename $sproxy[0] ($CurSel[0] + "_Smooth")`;
select $proxy;
createDisplayLayer -name "ProxyObject_L";
layerEditorLayerButtonTypeChange ProxyObject_L;
layerEditorLayerButtonTypeChange ProxyObject_L;
}

Basically, all you need to do, at the top of your script (outside of any procedure) declare your global string
global string $base[];
hen in the procedures you want to access the 'base' variable you have to define
global string $base[];
this tells the interpreter that when you reference the $base variable in that procedure, you are going to use the global one, not a local one.

If you fail to declare the global variable in the procedure aswell, you will create a local $base variable.

in your case:

global string $base[];

global proc spsbs_c()
{
global string $base[];

//Selection Control
string $CurSel[] = `filterExpand -sm 12`;
.
.
.
//Operation BaseObject
string $base = $CurSel[0];
select $base;
createDisplayLayer -name "BaseObject_L";
.
.
.


Does that help?

[safakoner]

Yes, thanks again. It works.

but

I define an object called $base. When I call the $base in other proc. that don't work.
My code is below, part 2 is not working. (delete proc). That is problem.
can you help me again ?

i've just tried this with a little test script.
It seems to work fine for me.. What error are you getting?
I used

global string $base[];
global proc test1 ()
{
global string $base[];
$base = `ls`;
}

global proc test2 ()
{
global string $base[];
delete $base;
}

test1;
test2;

and the only error I got was that the nodes (empty scene) cannot be deleted.
Which should mean that the script syntax is correct...

[safakoner]

its working. :bounce: But I can't use this code for my script.

Thanks for help
