Parent, Zero Out Transforms, Unparent

Hey Guys,

Im VERY new to MEL-Scripting and I'm trying to do the following in a script:

Before the script:

1. select 1 Object (object1)

2. select a second Object (object2)

The Script:

1.Parent object1 to object2 (so object2 is the parent of object1)

2. Zero Out Transforms (translate+rotate) of object2

3. Unparent object2

My Problem: Parenting and unparenting seems to be working correctly. But my script also sets the values of the Parent to 0, but i only want to set the values of the originally second selected object to 0.

Here is the exact Script I am using:

{ string $nodes[] = `ls -selection`; parent; select ($nodes [1]) int $rX = getAttr ($node[1] + ".rotateX")`; int $rY = getAttr ($node[1] + ".rotateY")`; int $rZ = getAttr ($node[1] + ".rotateZ")`; int $tX = getAttr ($node[1] + ".translateX")`; int $tY = getAttr ($node[1] + ".translateY")`; int $tZ = getAttr ($node[1] + ".translateZ")`; setAttr ($node[1] + ".rotateX") ($rX = 0); setAttr ($node[1] + ".rotateY") ($rY = 0); setAttr ($node[1] + ".rotateZ") ($rZ = 0); setAttr ($node[1] + ".translateX") ($tX = 0); setAttr ($node[1] + ".translateY") ($tY = 0); setAttr ($node[1] + ".translateZ") ($tZ = 0); parent -w; }

Hi!

It's not clear from your description and your code what you want to do exactly, but it seems you want to move one object to the same position of the other object.

In this case simply try

matchTransform

Your code also has many error, so if you still want to use this try as starting point:

{ string $nodes[] = `ls -selection`; parent; setAttr ($nodes[0] + ".rotateX") ($rX = 0); setAttr ($nodes[0] + ".rotateY") ($rY = 0); setAttr ($nodes[0] + ".rotateZ") ($rZ = 0); setAttr ($nodes[0] + ".translateX") ($tX = 0); setAttr ($nodes[0] + ".translateY") ($tY = 0); setAttr ($nodes[0] + ".translateZ") ($tZ = 0); parent -w $nodes[0]; }

{ string $nodes[] = `ls -selection`; parent; setAttr ($nodes[1] + ".rotateX") ($rX = 0); setAttr ($nodes[1] + ".rotateY") ($rY = 0); setAttr ($nodes[1] + ".rotateZ") ($rZ = 0); setAttr ($nodes[1] + ".translateX") ($tX = 0); setAttr ($nodes[1] + ".translateY") ($tY = 0); setAttr ($nodes[1] + ".translateZ") ($tZ = 0); parent -w $nodes[0]; }

based on the object transforms you want to zero out.

Thanks for the quick response! I actually didnt even execute the script that i posted above. I am very lost right now in the Scripting environment of Maya. But you helped me doing my first steps! BIG THANKS.
