 GamePiece inner)

Method Details

getDescription

public String getDescription()

Description copied from interface: EditablePiece

A plain-English description of this type of trait/piece - includes data from fields where appropriate

Specified by:

getDescription in interface EditablePiece

getBaseDescription

public String getBaseDescription()

Description copied from interface: EditablePiece

Support for a basic-name-only description introduced later, so this default retrofits it from the full description if an explicit one is not defined.

Specified by:

getBaseDescription in interface EditablePiece

Returns:

name of trait/piece type, w/o additional data

getDescriptionField

public String getDescriptionField()

Description copied from class: Decorator

If Decorator contains a description *field*, returns the current contents of it.

Overrides:

getDescriptionField in class Decorator

Returns:

contents of "description" field, if it exists.

myGetType

public String myGetType()

Description copied from class: Decorator

The "type information" of a piece or trait is information that does not change during the course of a game. Image file names, context menu strings, etc., all should be reflected in the type. The type information is returned serialized string form, ready to be decoded by a SequenceEncoder#decode.

Specified by:

myGetType in class Decorator

Returns:

the type information of this trait alone

See Also:

• BasicCommandEncoder
• which returns type information for all inward piece members as well

mySetType

public void mySetType(String type)

Description copied from interface: EditablePiece

Sets the information for this piece. See Decorator.myGetType()

Specified by:

mySetType in interface EditablePiece

Parameters:

type - a serialized configuration string to set the "type information" of this piece, which is information that doesn't change during the course of a single game (e.g. Image Files, Context Menu strings, etc). Typically ready to be processed e.g. by SequenceEncoder.decode()

myGetState

public String myGetState()

Description copied from class: Decorator

The "state information" is "game state" information that can change during the course of a game. State information is saved when the game is saved and is transferred between players on the server. For example, the relative order of pieces in a stack is state information, but whether the stack is expanded is not.

Specified by:

myGetState in class Decorator

Returns:

the game state information of this trait alone

See Also:

• which returns state information for all inward piece members as well

mySetState

public void mySetState(String newState)

Description copied from class: Decorator

Sets the state of this-trait-only (inverse of Decorator.myGetState()). The "state information" is information that can change during the course of a game. State information is saved when the game is saved and is transferred between players on the server. For example, the relative order of pieces in a stack is state information, but whether the stack is expanded is not.

Specified by:

mySetState in class Decorator

Parameters:

newState - New state information serialized in string form, ready to be passed to a SequenceEncoder#decode.

boundingBox

public Rectangle boundingBox()

Specified by:

boundingBox in interface GamePiece

Returns:

The area which this GamePiece occupies when drawn at the point (0,0)

getShape

public Shape getShape()

Specified by:

getShape in interface GamePiece

Returns:

The shape of the piece from the user's viewpoint. This defines the area in which the user must click to select or move the piece, for example. Like GamePiece.boundingBox(), it assumes the position is (0,0) -- which to be clear is normally aligned with the CENTER of the piece image -- and must be translated to the actual location where the piece is being drawn. For most ordinary pieces, the shape returned here will simply be equivalent to the bounding box, but see NonRectangular.

getName

public String getName()

Description copied from interface: GamePiece

The plain English name for this piece

Specified by:

getName in interface GamePiece

isLocallyActive

public boolean isLocallyActive()

isGloballyActive

public boolean isGloballyActive()

isActive

public boolean isActive()

getNamedKeyStrokeList

public List<NamedKeyStroke> getNamedKeyStrokeList()

Description copied from class: Decorator

SearchTarget

Specified by:

getNamedKeyStrokeList in interface SearchTarget

Overrides:

getNamedKeyStrokeList in class Decorator

Returns:

a list of any Named KeyStrokes referenced in the Decorator, if any (for search)

getMenuTextList

public List<String> getMenuTextList()

Description copied from class: Decorator

SearchTarget

Specified by:

getMenuTextList in interface SearchTarget

Overrides:

getMenuTextList in class Decorator

Returns:

a list of any Menu Text strings referenced in the Decorator, if any (for search)

draw

public void draw(Graphics g,
 int x,
 int y,
 Component obs,
 double zoom)

Description copied from interface: GamePiece

Draw this GamePiece

Specified by:

draw in interface GamePiece

Parameters:

g - target Graphics object

x - x-location of the center of the piece

y - y-location of the center of the piece

obs - the Component on which this piece is being drawn

zoom - the scaling factor.

getArea

protected Area getArea()

getRadius

protected int getRadius()

myGetKeyCommands

protected KeyCommand[] myGetKeyCommands()

Specified by:

myGetKeyCommands in class Decorator

Returns:

the key commands for this trait alone

See Also:

• which returns the key commands for this trait AND all inner piece members

myKeyEvent

public Command myKeyEvent(KeyStroke stroke)

Description copied from class: Decorator

The response of this trait alone to the given KeyStroke or the virtual keystroke of a NamedKeyStroke. NamedKeyStrokes are allocated a unique internal KeyStroke when they are first used in a module, and that KeyStroke is passed up and down the decorator stack to represent them (see NamedKeyStroke.getKeyStroke()).

Specified by:

myKeyEvent in class Decorator

Parameters:

stroke - KeyStroke to apply (to apply a Named Keystroke send NamedKeyStroke.getKeyStroke()

Returns:

Generated Command to reproduce any changes just made to to the game state, or null if no effect

See Also:

• Decorator.keyEvent(javax.swing.KeyStroke)

getHelpFile

public HelpFile getHelpFile()

Specified by:

getHelpFile in interface EditablePiece

Returns:

the help file for this trait

getEditor

public PieceEditor getEditor()

Specified by:

getEditor in interface EditablePiece

Overrides:

getEditor in class Decorator

Returns:

the configurer for this trait - the dialog which allows the editing the piece's type information. Default configurer is a SimplePieceEditor, but many traits will want to provide custom versions.

getArea

public Area getArea(MapShader shader)

Description copied from interface: MapShader.ShadedPiece

Returns the Area to add to (or subtract from) the area drawn by the MapShader's. Area is assumed to be at zoom factor 1.0

Specified by:

getArea in interface MapShader.ShadedPiece

Parameters:

shader - Map Shader

Returns:

the Area contributed by the piece

getProperty

public Object getProperty(Object key)

Return the active state of the trait

Specified by:

getProperty in interface GamePiece

Specified by:

getProperty in interface PropertySource

Overrides:

getProperty in class Decorator

Parameters:

key - Property name

Returns:

state

getLocalizedProperty

public Object getLocalizedProperty(Object key)

Specified by:

getLocalizedProperty in interface PropertySource

Overrides:

getLocalizedProperty in class Decorator

Parameters:

key - String key of property to be returned

Returns:

Object containing localized text of the specified property, if available, otherwise non-localized value

public List<String> getPropertyNames()

Specified by:

getPropertyNames in interface PropertyNameSource

Overrides:

getPropertyNames in class Decorator

Returns:

List of property names "exposed" by this piece -- that are available to other Traits and components to read. Default behavior for a Trait is not to expose any properties, but Traits which should expose some (e.g. DynamicProperty or Marker) would provide an array of the property names here.

getPropertyList

public List<String> getPropertyList()

Description copied from class: Decorator

SearchTarget

Specified by:

getPropertyList in interface SearchTarget

Overrides:

getPropertyList in class Decorator

Returns:

a list of any Property Names referenced in the Decorator, if any (for search)

testEquals

public boolean testEquals(Object o)

Description copied from class: Decorator

Test if this Decorator's Class, Type and State are equal to another trait. Implementations of this method should compare the individual values of the fields that make up the Decorators Type and State. Implementations should NOT compare the values returned by myGetType() or myGetState(). This method is intended to be used by Unit Tests to verify that a trait is unchanged after going through a process such as serialization/deserialization.

Overrides:

testEquals in class Decorator

Parameters:

o - Object to compare this Decorator to

Returns:

true if the Class, type and state all match

getI18nData

public PieceI18nData getI18nData()
