Instanciate onto a GameObject

nooby question here but i was wondering how i use the instantiate function to attach the clone onto a gameObject so that if i move the gameObject i will also move the clones.

Just set the instantiated object’s transform parent property to the transform of the GameObject you wish to attach it to. Along the lines of:

newObject.transform.parent = otherObject.transform;

I made a simple tutorial with javascript samples about - how to combine several models together. That is if you have a character with skeletal animation and you want to change his/her pants or sweater in real time
