public abstract class Spatial
extends java.lang.Object
implements Savable, java.lang.Cloneable, Collidable, CloneableSmartAsset, JmeCloneable, HasLocalTransform

```
    Serialization only. Do not use. Not really. This class is never instantiated directly but the subclasses like to use the no-arg constructor for their own no-arg constructor... which is technically weaker than forward supplying defaults.

public void setKey(AssetKey key)

    Description copied from interface: CloneableSmartAsset
    
    Set by the AssetManager to track this asset. Only clones of the asset has this set, the original copy that was loaded has this key set to null so that only the clones are tracked for garbage collection.
    
    Specified by:
    
    setKey in interface CloneableSmartAsset
    
    Parameters:
    
    key - The AssetKey to set
  - getKey
```
public AssetKey getKey()
```
    Description copied from interface: CloneableSmartAsset
    
    Returns the asset key that is used to track this asset for garbage collection.
    
    Specified by:
    
    getKey in interface CloneableSmartAsset
    
    Returns:

  - setRequiresUpdates
```
protected void setRequiresUpdates(boolean f)
```
    Subclasses can call this with true to denote that they require updateLogicalState() to be called even if they contain no controls. Setting this to false reverts to the default behavior of only updating if the spatial has controls. This is not meant to indicate dynamic state in any way and must be called while unattached or an IllegalStateException is thrown. It is designed to be called during object construction and then never changed, ie: it's meant to be subclass specific state and not runtime state. Subclasses of Node or Geometry that do not set this will get the old default behavior as if this was set to true. Subclasses should call setRequiresUpdate(false) in their constructors to receive optimal behavior if they don't require updateLogicalState() to be called even if there are no controls.
    
    Parameters:
    
    f - true→require updates, false→don't require updates

```
public void rotateUpTo(Vector3f newUp)
```
    rotateUpTo is a utility function that alters the local rotation to point the Y axis in the direction given by newUp.
    
    Parameters:
    
    newUp - the up vector to use - assumed to be a unit vector.
  - lookAt
```
public void lookAt(Vector3f position,
                   Vector3f upVector)
```
    lookAt is a convenience method for auto-setting the local rotation based on a position in world space and an up vector. It computes the rotation to transform the z-axis to point onto 'position' and the y-axis to 'up'. Unlike Quaternion.lookAt(com.jme3.math.Vector3f, com.jme3.math.Vector3f) this method takes a world position to look at and not a relative direction. Note : 28/01/2013 this method has been fixed as it was not taking into account the parent rotation. This was resulting in improper rotation when the spatial had rotated parent nodes. This method is intended to work in world space, so no matter what parent graph the spatial has, it will look at the given position in world space.
    
    Parameters:
    
    position - where to look at in terms of world coordinates
    
    upVector - a vector indicating the (local) up direction. (typically {0, 1, 0} in jME.)
