Revision history for Perl extension Games::Object.

0.11  Wed Oct 15 2003

    This is a patch release only to fix critical bugs:

    - Fixed bug in save() where -filename was not parsed properly.

    - Fixed bug in define_relation() where the relate_method was being used
      as the name passed from the relator instead of the actual name of the
      relationship. Changed relate.t test to tickle this bug again if it
      ever resurfaces.

    - Adding manager code broke flag inheritance. Fixed. Also added missing
      tests for flag inheritance to inherit.t

    - Undefined flags no longer croak(), but instead simply return false,
      in order to be consistent with the way attributes work.

0.10  Tue Jul 29 2003
	WARNING: This version is a redesign of several key components of the
	system. This version is most likely incompatible with all older
	versions.

	Instead of using Games::Object as the object manager as well as the
	object structure, a new Games::Object::Manager module has been added.
	A manager acts as a container for objects, thus stuff that used to
	be functions (like Find(), Process(), etc) are now methods on the
	manager. Thus you can manage several lists of self-contained objects.
	This is much more in keeping with an overall OO approach.

	The event system was ripped out and rewritten from scratch. The
	new version is much more integrated into the objects, so it appears
	more seamless. This has the nice side-effect of getting rid of the
	GlobalObject kludginess. The new code is actually smaller than the
	original.

	With the introduction of object managers, I have been able to provide
	a framework for defining and tracking object relationships. Object
	inheritance is now simply a predefined object relationship referenced
	by the Games::Object module.

	Ripped out the class registration code for non-Games::Object derived
	object references. Instead, I simply require that you have a load() and
	save() method to handle file IO (id and find methods no longer needed).
	This is more in keeping with OO programming methodology.

	A new flag provided to have simplified accessor methods autocreated
	for you when adding attributes (and yes, I considered using AUTOLOAD,
	but I don't much care for it because of the inheritance nightmare,
	and to quote the Perl Cookbook: "AUTOLOAD eventually begins to feel
	like a kludge piled on a hack piled on a workaround")

	User-defined object flags are created on objects on the fly as needed,
	much like attributes, rather than requiring the user to predefine
	them globally.

	You can now choose the starting ID for auto-generated object IDs (object
	IDs now maintained by the object manager module).

	Fixed bug where -w on Perl 5.8.0 gave "v-string ... non-portable"
	warning.

	Added overloaded operators so objects can be compared more easily.

	You can now specify an arbitrary filter function when processing all
	objects in a manager (i.e. the functionality handled by Process()
	in previous versions).

	Adjusted some tests to deal with Perl 5.8.0 weirdness causing false
	test failures on some platforms (this one a suspected mathematical
	precision problem).

0.05  Mon Nov 25 2002
	Added a feature that allows a more deterministic way of specifying
	processing order of objects with the same priority.

	Fixed a false assumption problem in event.t that caused a test
	failure under Perl 5.8.0.

	Persistent mods can now be made to take effect immediately by adding
	-apply_now => 1 to the mod_attr() call. This indirectly helps
	alleviate the timing issue with process(), enough that I have removed
	it from the BUGS section.

	Persistent mods can now work properly with attributes at OOB conditions.
	This was more a documentation change than a code change, as this
	feature was always present, but was not obvious from the docs.

	Added ability to inherit attribute values via object parenting. Added
	the corresponding inherit.t test suite.

	Made some corrections to examples in the POD docs.

0.04  Sat Jun  8 2002
	Much of the changes here are to support the upcoming release of the
	Games::TileMap module.

	This module now requires a minimum Perl version of 5.6.0.

	Added ability to assert validity of ID in Find() and fail if not valid.

	Added the Id() function to achieve similar assertion functionality.

	Added the objectDestroyed event, triggered when destroy() is called on
	an object.

	Added attr_ref() to allow attributes to be used in -textvariable
	and -variable options in Perl Tk widgets.

	Fixed bug in load() that caused an annoying but harmless "substr
	outside of string" warning under -w if the save file had undefined
	hash values.

	Documented the attribute flags and added flag ATTR_AUTOCREATE.

0.03  Sat Apr  6 2002
	Completely reworked the event handling mechanism to allow events
	to be targeted for specific objects.

	Events also now trigger as soon as they happen. Queueing them didn't
	really make any sense once I really looked at it.

	The "round" option for -on_fractional now works properly.

	Added events objectLoaded and objectSaved to allow for class-specific
	data manipulation.

	Fixed bug where the persistent mod table was not being initialized
	properly and probably caused perl to complain under -w, though the
	code still worked.

	Altered the default process_list by removing the second call to
	process_queue(), since the changes to the event structure obviates
	the need for this.

	Expanded the priority.t test suite to cover tend-to and persistent mods.

	Added event.t test suite.

	Corrected some erroneous examples in the docs.

	Put the perldoc stuff into a separate file, as it was growing
	as large as the code itself.

0.02  Sun Feb 24 2002
	The docs stated that a reference to an object subclassed to
	Games::Object assigned to an attribute of 'any' would save/load
	the reference correctly. Now it really does.

	The docs also stated that GLOB references worked in the -file
	parameter to new(), load(), and save(). Now they really do.

	Added attr_exists() and del_attr().

	attr() and raw_attr() no longer croak with the attribute does not
	exist; they simply return undef instead.

	Added 'readable_filename' as a datatype to FetchParams()

	Added function TotalObjects()

	Added some missing tests to loadsave.t (object references and
	PLACEHOLDER functionality)

0.01  Sun Jan 20 2002
	Initial alpha release. Probably stable, but lacking in some polish
	and some functionality. Reasonably comprehensive docs, though.
