- Method Detail
  - getInternalState
```
AttachmentInternalState getInternalState()
```
    Gets controller internal state information. Should return the same instance all the time. Internal use only.
    
    Returns:
    
    state information
  - getManager
```
default AttachmentManager getManager()
```
    Gets the attachment manager instance that initialized this attachment and oversees its interaction with the outside environment.
    
    Returns:
    
    attachment manager
  - getConfig
```
default com.bergerkiller.bukkit.common.config.ConfigurationNode getConfig()
```
    Gets the configuration of this attachment. This is automatically populated with the attachment's configuration before onAttached() is called. The configuration is mutable, and when properties of the attachment are changed, they should be updated in the configuration before or during onDetached().
    
    Returns:
    
    configuration
  - onAttached
```
void onAttached()
```
    Called when the controller is attached to the real world. From this point onwards further initialization can be performed.
  - onDetached
```
void onDetached()
```
    Called when the controller is detached from the real world. After this call all stored information in the controller is invalid, until onAttached() is called again. #onSave(config) is called before this method is called, if saving is required.
  - onLoad
```
void onLoad(com.bergerkiller.bukkit.common.config.ConfigurationNode config)
```
    Called when the attachment need to (re)load the configuration. This method is called after onAttached() is called for the first time, and when configuration is reloaded while the attachment remains attached. A guarantee is made that the attachment will be attached when this method is called.
    
    Parameters:
    
    config - The configuration of the attachment
  - onTick
```
void onTick()
```
    Called every tick to update the attachment
  - onTransformChanged
```
void onTransformChanged(com.bergerkiller.bukkit.common.math.Matrix4x4 transform)
```
    Called right after the getTransform() has been updated. Additional transformations can be performed here on the transformation matrix, and position information can be calculated.
    
    Parameters:
    
    transform - (same as getTransform() but mutable)
  - onMove
```
void onMove(boolean absolute)
```
    Called every now and then to refresh the position of the attachment
    
    Parameters:
    
    absolute - whether this is an absolute (synchronize) movement update. If this is true, the position information should be refreshed.
  - isAttached
```
default boolean isAttached()
```
    Gets whether this attachment has been attached. This returns true if onAttached() was last called. It returns false if this was never called, or onDetached() was last called.
    
    Returns:
    
    True if this attachment has been attached
  - isFocused
```
default boolean isFocused()
```
    Gets whether this attachment is focused. This returns true if onFocus() was last called. It returns false if this was never called, or onBlur() was last called.
    
    Returns:
    
    True if this attachment receives focus
  - setFocused
```
default void setFocused(boolean focused)
```
    Sets whether this attachment is focused. This changes the isFocused() state, as well call the onFocus() or onBlur() callbacks as required.
    
    Parameters:
    
    focused - state to set to
  - onFocus
```
default void onFocus()
```
    Called when an attachment is focused in the editor or by other means. The attachment should try to change appearance to indicate it received focus.
  - onBlur
```
default void onBlur()
```
    Called when an attachment loses focus in the editor or by other means. The attachment should reset the appearance changes that were performed by onFocus().
  - makeVisible
```
void makeVisible(org.bukkit.entity.Player viewer)
```
    Makes this attachment visible to a viewer for the first time. This is automatically called for you after onAttached() is called, and whenever a new viewer moves within range.
    
    Parameters:
    
    viewer - to make it visible to
  - makeHidden
```
void makeHidden(org.bukkit.entity.Player viewer)
```
    Makes this attachment invisible (despawns) for a viewer. This is automatically called for you before onDetached() is called, and whenever a new viewer moves out of range.
    
    Parameters:
    
    viewer - to hide it from
