Method Detail

initialize

public void initialize()

Description copied from interface: GameObject

Initializes the object's default properties. Any GameObject implementation that wishes to initialize itself should do so here, rather than in the constructor. This is because nearly all game objects inherit from an archetype, and the archetype parent pointer isn't set until the object's constructor finishes. This is a good place to add any class-default properties for an object - properties that the object gets regardless of which archetype it inherits from. WARNING: don't forget to call the superclass' initialize() method, or the object may not function properly. For instance, it won't become animated even if it specifies animation parameters in the archetype.

Specified by:

initialize in interface GameObject

Overrides:

initialize in class Teleporter

knowsCommand

public boolean knowsCommand(java.lang.String cmd)

Handles "up" if we have the "goes-up" property, "down" if we have the "goes-down" property.

Specified by:

knowsCommand in interface Command

Parameters:

cmd - the command the user typed

Returns:

true if we want to handle the command

createEvent

public CommandEvent createEvent(CommandEvent e)

Description copied from interface: Command

Creates a CommandEvent that encapsulates all the state necessary to perform the command. A well-designed CommandEvent exposes all of its "properties" so that hook objects can modify its behavior. For instance, many commands result in some sort of message being sent back to the client. The message should be among the properties that hooks can override.

This method is called by the kernel. The kernel passes the event to the pre-hook, then calls Command.execute() (below) to execute the event, and finally calls the post-hook.

Specified by:

createEvent in interface Command

Parameters:

e - a "blank" CommandEvent containing only the command text and the agent who's performing the command. This initial event is created by the originator of the event (e.g. the AI or player's command preprocessor).

Returns:

a CommandEvent subclass encapsulating this command's execution parameters and state. It should copy in the fields from the passed-in event.

execute

public boolean execute(CommandEvent event)

Description copied from interface: Command

Executes the specified CommandEvent. The CommandEvent contains all the parameters and state required to execute the command; the parameters have been filtered through hook objects, so they may not be the same as when the event was created.

Specified by:

execute in interface Command

Parameters:

event - the CommandEvent to execute

Returns:

true if the event completed successfully, else false.
