    Set the shape of the water area (Circular (default) or Square). if the shape is square the radius is considered as an extent.
    
    Parameters:
    
    shapeType - the shape type
  - 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.
  - setNeedSaveReflectionScene
```
public void setNeedSaveReflectionScene(boolean needSaveReflectionScene)
```
    Sets the flag.
    
    Parameters:
    
    needSaveReflectionScene - true if need to save reflection scene.
  - isNeedSaveReflectionScene
```
public boolean isNeedSaveReflectionScene()
```
    Returns:
    
    true if need to save reflection scene.
