  - jmeClone
```
public java.lang.Object jmeClone()
```
    Description copied from interface: JmeCloneable
    
    Performs a regular shallow clone of the object. Some fields may also be cloned but generally only if they will never be shared with other objects. (For example, local Vector3fs and so on.)
    This method is separate from the regular clone() method so that objects might still maintain their own regular java clone() semantics (perhaps even using Cloner for those methods). However, because Java's clone() has specific features in the sense of Object's clone() implementation, it's usually best to have some path for subclasses to bypass the public clone() method that might be cloning fields and instead get at the superclass protected clone() methods. For example, through super.jmeClone() or another protected clone method that some base class eventually calls super.clone() in.
    
    Specified by:
    
    jmeClone in interface JmeCloneable
  - cloneFields
```
public void cloneFields(Cloner cloner,
                        java.lang.Object original)
```
    Description copied from interface: JmeCloneable
    
    Implemented to perform deep cloning for this object, resolving local cloned references using the specified cloner. The object can call cloner.clone(fieldValue) to deep clone any of its fields.
    Note: during normal clone operations the original object will not be needed as the clone has already had all of the fields shallow copied.
    
    Specified by:
    
    cloneFields in interface JmeCloneable
    
    Parameters:
    
    cloner - The cloner that is performing the cloning operation. The cloneFields method can call back into the cloner to make clones of its subordinate fields.
    
    original - The original object from which this object was cloned. This is provided for the very rare case that this object needs to refer to its original for some reason. In general, all of the relevant values should have been transferred during the shallow clone and this object need merely clone what it wants.

```
    Only has an effect if smoothMotion is set to true and trailing is enabled Sets the trailing sensitivity, the lower the value, the slower the camera will go in the target trail when it moves. default is 0.5;

    trailingSensitivity -
  - getZoomSensitivity
```
public float getZoomSensitivity()
```

    Returns:
    
    the sensitivity
  - setZoomSensitivity
```
public void setZoomSensitivity(float zoomSensitivity)
```
    Sets the zoom sensitivity, the lower the value, the slower the camera will zoom in and out. default is 2.
    
    Parameters:
    
    zoomSensitivity -
  - getRotationSpeed
```
public float getRotationSpeed()
```
    Returns the rotation speed when the mouse is moved.
    
    Returns:
    
    the rotation speed when the mouse is moved.
  - setRotationSpeed
```
public void setRotationSpeed(float rotationSpeed)
```
    Sets the rotate amount when user moves his mouse, the lower the value, the slower the camera will rotate. default is 1.
    
    Parameters:
    
    rotationSpeed - Rotation speed on mouse movement, default is 1.
  - setDefaultDistance
```
public void setDefaultDistance(float defaultDistance)
```
    Sets the default distance at start of application
    
    Parameters:
    
    defaultDistance -
  - setDefaultHorizontalRotation
```
public void setDefaultHorizontalRotation(float angleInRad)
```
    sets the default horizontal rotation in radian of the camera at start of the application
    
    Parameters:
    
    angleInRad -
  - setDefaultVerticalRotation
```
public void setDefaultVerticalRotation(float angleInRad)
```
    sets the default vertical rotation in radian of the camera at start of the application
    
    Parameters:
    
    angleInRad -
  - isDragToRotate
```
public boolean isDragToRotate()
```
    Returns:
    
    If drag to rotate feature is enabled.
    
    See Also:
    
    setDragToRotate(boolean)
  - setDragToRotate
```
public void setDragToRotate(boolean dragToRotate)
```
    Parameters:
    
    dragToRotate - When true, the user must hold the mouse button and drag over the screen to rotate the camera, and the cursor is visible until dragged. Otherwise, the cursor is invisible at all times and holding the mouse button is not needed to rotate the camera. This feature is disabled by default.
  - setDownRotateOnCloseViewOnly
```
public void setDownRotateOnCloseViewOnly(boolean rotateOnlyWhenClose)
```
    Parameters:
    
    rotateOnlyWhenClose - When this flag is set to false the chase camera will always rotate around its spatial independently of their distance to one another. If set to true, the chase camera will only be allowed to rotated below the "horizon" when the distance is smaller than minDistance + 1.0f (when fully zoomed-in).
  - getDownRotateOnCloseViewOnly
```
public boolean getDownRotateOnCloseViewOnly()
```
    Returns:
    
    True if rotation below the vertical plane of the spatial tied to the camera is allowed only when zoomed in at minDistance + 1.0f. False if vertical rotation is always allowed.
  - getDistanceToTarget
```
public float getDistanceToTarget()
```
    return the current distance from the camera to the target
    
    Returns:
    
    the distance
