Here is what i'm trying to do:
Select spine joints one by one, check if their Y rotateaxis' are less than 0, if so rotate 180 degrees, otherwise do nothing.

I've started with a selection array that lists their rotateAxis'

string $spineRot[] = `ls ("spine*JNT.rotateAxis")` ;
$spine = `getAttr $spineRot` ;

I'm having trouble using that info in a statement. Should I be using a if-else solution or a for-in loop and what might it look like?

Thanks for any help

Hi !

here is what I would do:

string $listSpineJoints[] = `ls ("spine*JNT") `;
string $SpineJoint ;

for ($SpineJoint in $listSpineJoints)
{

float $rotation = `getAttr ($SpineJoint+".ry")`;

if ( $rotation < 0 )

{
setAttr ($SpineJoint+".ry") ($rotation+180) ;
}

}

I hope that will help you.

thanks for your response nendo

could someone explain to me what a for-in loop does and how it actually works

thanks

Here is the solution I ended up with for the problem I posted:

string $listSpineJoints[] = `ls ("spine*JNT")` ;
string $spineJoint ;
for ($spineJoint in $listSpineJoints)
{
float $rotation = `getAttr ($spineJoint + ".rotateAxisY")` ;

if ($rotation < 0)
{
select ($spineJoint + ".rotateAxis") ;
rotate -r -os 180 0 0 ;
}
}
