Saving an object state and being able to restore it later

Questions & Answers
1

Hey guys, I have a script that on a button S(ave) press saves a given object’s position, rotation, velocity and angular velocity.

Then another button R(estore) assigns them back so the object goes back to the same position/rotation/velocity/angular velocity that it had during Save.
The only problem is, that with more complex bodies - such as with a ragdoll, on each restore, the ragdoll behaves different, I wonder what the hell is wrong with my script.
which is basically:

var trPosition:Vector3;
var quatRotation:Quaternion;
var velocity:Vector3;
var angVelocity:Vector3;

function Savee(){
		trPosition = transform.position;
		quatRotation = transform.rotation;
		velocity = rigidbody.velocity;
		angVelocity = rigidbody.angularVelocity;
		}
function Restoree(){
		transform.position = trPosition;
		transform.rotation = quatRotation;
		rigidbody.velocity = velocity;
		rigidbody.angularVelocity = angVelocity;
		}

P.S. it shouldn’t be relevant to the problem but here is the script that calls it:
basically every object that will need saving like that, has the script above, and there’s one “ultraparent” who uses the script to call Save(e)s and Restore(e)s:

var ultraParent:Transform; //a parent of anything that needs to be saved and restored
    function Update () {
    	if(Input.GetKeyDown(KeyCode.S)){
    		for(var child in ultraParent){
    			var temp = child.GetComponent(Snapshot);
    			if(temp)
    				temp.Savee();
    				}		
    	}
    	
    	if(Input.GetKeyDown(KeyCode.R)){		
    		for(var child in ultraParent){
    			temp = child.GetComponent(Snapshot);
    			if(temp)
    				temp.Restoree();
    				}		
    	}
    	
    }

Unless you are saving a ‘deep copy’ of the object (meaning all the states of all its children), and restoring them, then my guess is that the ragdoll stuff has some randomness to it that lets the joints flop around and that will be different each time. Try iterating through the children recursively and save/restore it all.
