proc AddLocator(){
string $nodes[] = `ls -selection`;
float $tX;
float $tY;
float $tZ;

for ( $node in $nodes ){
$tX = `getAttr $node.translateX`;
$tY = `getAttr $node.translateY`;
$tZ = `getAttr $node.translateZ`;
}
}

當我SELECTED ojbect 多過一件時,
點解getAttr $node.translateX return float[] but not float?

i print $node out is one object from selected object, but the getAttr $node.translateX return all the translateX of selected objects in a float array. WHY?

[vectoreffect]

`ls -selection`will return a string array. Therefore, you need to create a float array to contain the translation data.

may be you could change it as follow:

proc AddLocator(){
string $nodes[] = `ls -selection`;
float $tX[];
float $tY[];
float $tZ[];

int $i_count = size($nodes);

for($i=0;$i<=($i_count-1);$i++){
$tX[$i] = `getAttr ($nodes[$i] + ".translateX")`;
$tY[$i] = `getAttr ($nodes[$i] + ".translateY")`;
$tZ[$i] = `getAttr ($nodes[$i] + ".translateZ")`;
}
}

THX. 解決了.

三句改為:

$tX = `getAttr ($node +".translateX")`;
$tY = `getAttr ($node +".translateY")`;
$tZ = `getAttr ($node +".translateZ")`;

THX~!
