Cannot convert data of type int[] to type int

[kursat-turkay]

hi there...
this script overrides toggle bounding box for individual objects ....

my questino is this : if my selection is more than 1. than this errors occurs :

Cannot convert data of type int[] to type int. //

global proc toggleviewAsBBox()
{
string $sel[] = ls -sl;
string $current;

if( size($sel) != 0 )
{
	for( $current in $sel )
	{
		string $ovr = $current + ".overrideEnabled";
		string $lod = $current + ".overrideLevelOfDetail";

		int $tgA=`getAttr $current ".overrideEnabled"`;

		//print $tgA[];
		int $tgA=!($tgA);
		setAttr $ovr $tgA;
		setAttr $lod $tgA;

		//print( "n" + "toggle view as box for: " + $current );
	}
}
else
{
	error( "Nothing Selected" );
}

}

changed to this line :

int $tgA=getAttr ($current + ".overrideEnabled");

but I dont know what makes difference....
any one know what is the difference ?

[pete1973]

as far as i know that has to do with combining strings with varaibles.
in this example you have variable $current, to which you add the string ".overrideEnabled". so with the brackets you tell maya to combine those before evaluation.

Theres no difference. Exleept offcourse thers one less variable.

Its just that maya will remeber what variables you have used from previous tests without protection blocks. So its totaly possible teh rerror is related to some of the variable allready been declared as a another type before the redeclaration. So the error may be ralated to nthing worg but rather residues of earlier testing duringf the session.
