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.

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()

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

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

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

keyEvent

public Command keyEvent(KeyStroke stroke)

Description copied from class: Decorator

The primary way for the piece or trait to receive events. Appends the command returned by Decorator.myKeyEvent(javax.swing.KeyStroke) with the command returned by the inner piece member's GamePiece.keyEvent(javax.swing.KeyStroke) method. KeyStroke events are forwarded to this method if they are received while the piece is selected (or as the result of e.g. a Global Key Command being sent to the piece). The class implementing GamePiece can respond in any way it likes. Actual key presses by the player, selected items from the right-click Context Menu, keystrokes "applied on move" by a Map that the piece has just moved on, and Global Key Commands all send KeyStrokes (and NamedKeyStrokes) which are passed to pieces and traits through this interface.

Specified by:

keyEvent in interface GamePiece

Overrides:

keyEvent in class Decorator

Parameters:

stroke - KeyStroke to apply (note that although they are passed as KeyStroke objects, they may be NamedKeyStroke objects)

Returns:

a Command that, when executed, will make all changes to the game state (maps, pieces, other pieces, etc) to duplicate what the Trait/Decorator plus any inner piece members did in response to this event, on another machine. Often a ChangePiece command, but for example if this keystroke caused the piece/trait to decide to fire off a Global Key Command, then the Command returned would include the entire results of that, appended as subcommands. Returns null if the keystroke did not produce an effect.

See Also:

• ForwardToKeyBuffer

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)

newTranslate

protected Command newTranslate(KeyStroke stroke)

movePiece

protected Command movePiece(GamePiece gp,
 Point dest)

classicTranslate

protected Command classicTranslate(KeyStroke stroke)

Classic Translate code. The original Move Fixed Distance code does not work properly in Triggers, creates additional Null actions and does not undo properly. Some modules may depend on this behaviour. Now depends on a Module level preference being turned on to use it.

moveTarget

protected Command moveTarget(GamePiece target)

translate

protected void translate(Point p)

findTarget

protected GamePiece findTarget(KeyStroke stroke)

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)

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.

getName

public String getName()

Description copied from interface: GamePiece

The plain English name for this piece

Specified by:

getName in interface GamePiece

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.

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.

getHelpFile

public HelpFile getHelpFile()

Specified by:

getHelpFile in interface EditablePiece

Returns:

the help file for this trait

getI18nData

public PieceI18nData getI18nData()

Description copied from class: Decorator

Return Internationalization (I18n) data for this piece

Specified by:

getI18nData in interface TranslatablePiece

Overrides:

getI18nData in class Decorator

Returns:

I18n data, used to hold translations of strings

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
