== Rubygame 2.6.4
Release focus: Bug fix.
=== Fixes
- Fixed: Rubygame's "require_path" setting in the gem spec was
interfering with ruby-opengl (and potentially others). [#43]
If you have problems loading ruby-opengl when Rubygame 2.6.* is
installed via RubyGems, you should uninstall all versions of the
Rubygame gem, then reinstall version 2.6.4 (or later).
== Rubygame 2.6.3
Release focus: Bug fixes.
=== Fixes
- Fixed: MouseMoved events always reported that all buttons were
being pressed, even when they were not. [#38]
- Fixed: MousePressed and MouseReleased events would raise an error
for mouse buttons larger than 5. [#40]
- Fixed: KeyPressed and KeyReleased events always reported that all
modifier keys were being pressed, even when they were not. [#41]
- Fixed: Rubygame would generate spurious WindowUnminimized,
InputFocusGained, and MouseFocusGained events (or the opposite)
whenever any one of those events actually occurred.
- Fixed: Surface#convert would raise NameError if no Screen was open,
due to a typo. [#42]
=== Other Changes
- Rubygame will now skip auto-initialization if the RUBYGAME_NOINIT
environment variable (`ENV["RUBYGAME_NOINIT"]`) is set to "1",
"true", or "yes" (case insensitive). You must set the environment
variable *before* doing `require "rubygame"`. This is intended
for special cases where auto-initialization is not wanted.
== Rubygame 2.6.2
Release focus: Bug fixes.
=== Fixes
- Fixed: Rubygame::Screen.set_mode and Rubygame::Screen.instance were
accidently lost during the FFI port. (Note: those methods are
deprecated, but kept for backwards compatibility. New code should
use Rubygame::Screen.new or Rubygame::Screen.open instead.)
== Rubygame 2.6.1
Release focus: Bug fixes.
=== Fixes
- Fixed: Rubygame::Mixer.open_audio was using a different default
audio format than it did in 2.5.3, which caused an error on Mac.
(Note: The Rubygame::Mixer.open_audio is deprecated, but kept for
backwards compatibility. Use Rubygame.open_audio instead.)
- Fixed: Rubygame no longer tries to load audio features if SDL_mixer
is not available. Trying to load them would cause an error, and
didn't match the old behavior.
== Rubygame 2.6.0
Release focus: Ported to FFI.
=== FFI
Rubygame is now pure Ruby, with no compiled C code. Instead, it uses
Ruby-FFI (or compatible FFI implementations) to directly access SDL
and related libraries. That means:
- It is much easier to install. You can install it directly from
RubyGems (`gem install rubygame`) on any operating system, and you
don't need a C compiler or SDL headers.
- It is now possible to use Rubygame on JRuby, and possibly on
- Rubygame will be slightly slower than before. But, the hard work is
still being done by SDL, so the speed decrease is only minor. The
increased portability and ease of future development greatly
outweighs the small speed loss.
Despite the major architectural change, Rubygame 2.6 API is meant to
be backwards compatible with Rubygame 2.5 and earlier. If you find an
API incompatibility, you should report it as a bug.
However, there are a few minor incompatibilities that are already known,
and most likely cannot or will not be fixed:
- Surface#flip now needs SDL_gfx to run. Before, it needed only plain
SDL, but the code for it was too slow when reimplemented in Ruby.
- Rubygame::VERSIONS[:sdl_gfx] now reports [0,0,0] when SDL_gfx is
available, instead of its real version number. SDL_gfx does not
currently provide any way to detect its version number at run time.
(VERSIONS still reports nil when SDL_gfx is not available, the same
as in 2.5 and earlier.)
=== Fixes
- Fixed: Surface#set_at() now correctly sets the pixel's opacity for
Surfaces with an alpha channel. If no opacity is given for the new
color (i.e. only RGB), the pixel will be fully opaque.
- Note: Due to a long-standing bug, Surface.new cannot create a
Surface with an alpha channel. Use Surface#to_display_alpha to
create an alpha-channeled copy of the Surface, or load an image
file that has an alpha channel already.
- Fixed: Music.load now automatically opens audio if needed. MP3s (and
perhaps other file types) would fail to load in some circumstances
if audio was not open.
=== Other Changes
- Rubygame now automatically initializes itself when loaded and cleans
itself up at exit. So, you no longer need to call Rubygame.init or
Rubygame.quit in your code (but it won't hurt if you do).
- Added: New sample application, a basic image viewer.
See samples/image_viewer.rb.
- Added: Documentation listing every keyboard symbol used by Rubygame.
See doc/keyboard_symbols.rdoc.
- Added: Guide to setting custom load parts for SDL libraries.
See doc/custom_sdl_load_paths.rdoc.
- Surface#alpha= is now a true alias for Surface#set_alpha. It was a
separate method before. It can still be used in the same way as
- Surface#colorkey= is now a true alias for Surface#set_colorkey. It
was a separate method before. It can still be used in the same way
as before.
== Rubygame 2.5.3
Release focus: Bug fixes.
=== Fixes
- Updated gemspec to list (install-time) dependency on Rake. [#24]
- Fixed: MouseMoved and JoyBallMoved were wrongly using unsigned ints
for relative x and y positions. [#26]
- Fixed: Clock#framerate returned Infinity under some conditions.
- Fixed: Panda demo used the wrong order of steps for redrawing sprites.
== Rubygame 2.5.2
Release focus: Bug fixes.
=== Fixes
- Fixed: HasEventHandler#handle (and other methods) dealt with
NoMethodError exceptions in a stupid way.
== Rubygame 2.5.1
Release focus: Bug fixes.
=== Fixes
- Fixed: Clock.delay would delay forever if the delay time and
granularity were very small.
- Fixed: Clock.delay would always be "nice" to other Ruby threads
during the final part of the delay, even if nice = false.
== Rubygame 2.5.0
Release focus: Clock improvements.
=== Features
- New and improved algorithm for calculating framerate.
- Better Clock compatibility with multithreaded applications:
- Clock.delay and Clock.wait now accept a new argument: +nice+.
If nice is +true+, these methods try to allow other ruby threads
to run during the delay. The default behavior is to block other
threads, as previous versions of Rubygame do.
- Added: Clock @nice.
This instance variable controls the +nice+ value used while
delaying in #tick (if framerate limiting is active).
- Better control over the balance between CPU usage and accuracy
when using Clock's framerate limiting:
- Added: Clock @granularity.
This instance variable controls the granularity value used while
delaying in #tick (if framerate limiting is active). Smaller
values lower CPU usage, but framerate limiting will be less
accurate if the granularity is lower than the system's actual
clock granularity. Use Clock#calibrate to find the best value for
the current system.
- Added: Clock#calibrate.
Call this after you create a Clock instance calibrate the Clock's
granularity to match the system's actual clock granularity. This
reduces wasteful CPU usage when using framerate limiting.
- New ClockTicked event for use with EventHandlers:
- Added: ClockTicked event class.
If you call Clock#enable_tick_events, Clock#tick will return an
instance of ClockTicked instead of the raw delay time in milliseconds.
- Added: TickTrigger event trigger class.
Matches ClockTicked events.
- HasEventHandler#make_magic_hooks accepts the symbol :tick to create a
- Added: Clock#frametime.
Returns the actual milliseconds per frame recorded by the Clock.
- New in-depth Clock tutorial, "Managing Framerate".
See doc/managing_framerate.rdoc[link:files/doc/managing_framerate_rdoc.html].
An accompanying code example has also been added, samples/framerate.rb.
- A few Screen additions:
- Added: Screen.get_resolution. Returns the user's desktop resolution.
Due to a limitation of SDL, this can ONLY be used when the Rubygame
window is closed (i.e. before you have called Screen.new, or after
you have called Screen.close).
- Added: Screen.close. Closes the Rubygame window, if it's open.
- Added: Screen.open?. True if the Rubygame window is open.
- Added: Screen.open (alias of Screen.new).
- Added: HasEventHandler#make_magic_hooks_for.
It's like make_magic_hooks, but the hook's owner will be the
specified object, instead of the object with the handler.
=== Other Stuff
- Various Clock fixes and improvements:
- Clock#tick when called for the first time, no longer considers the
creation time of the Clock instance to be "the previous tick",
when checking how much time has passed.
- Clock#tick won't do any extra delay if the frame has already taken
longer than the target.
- Clock.delay and Clock.wait handle negative numbers more gracefully.
Instead of hanging for a long time, they act as if the values were 0.
- Deprecation: Screen.set_mode and Screen.instance (both aliases of
Screen.new) are deprecated and will be removed in Rubygame 3.0.
Use Screen.new or Screen.open instead.
- Deprecation: Ftor is deprecated and will be removed in Rubygame 3.0.
A mostly-compatible vector class will be provided at or before that time.
- Deprecation: MediaBag is deprecated and will be removed in Rubygame 3.0.
Use the NamedResource functionality of Music, Sound, and Surface instead.
== Rubygame 2.4.1
Release focus: Bug fixes; Ruby 1.9 compatibility.
=== Fixes
- Fixed: Module scope problems with EventHandler and triggers.
They were trying to find the Events module, which only worked if
you had done 'include Rubygame' somewhere.
- Fixed: Compiler warning in unmake_symbol().
=== Other Stuff
- Rubygame is compatible with Ruby 1.9.
- Build system is compatible with Ruby 1.9.
- Minor cleanup to build system internals.
== Rubygame 2.4.0
Release focus: Events.
=== Features
- New Events module, with a suite of new and revised event classes.
The new classes offer full functionality as the older classes.
- Use Rubygame::EventQueue#enable_new_style_events to enable the new
event classes. This will become the default in Rubygame 3.0.
- Uses symbols instead of integer constants for keyboard keys and
mouse buttons (e.g. :a, :space, :mouse_left, :mouse_right).
- Better unicode / international keyboard text input support.
(See Rubygame::Events::KeyPressed#string)
- More natural and memorable class naming scheme.
- New hook-based event handling system.
(NOTE: Requires use of the new event classes.)
- Rubygame::EventHandler class.
EventHandler holds many EventHook instances. It handles each event
by passing it to matching hooks.
- Rubygame::EventHandler::HasEventHandler mixin module.
Include this in your custom classes to add easy event handling
and event hook creation abilities.
- Rubygame::EventHook class.
- Rubygame::EventActions module.
Has several pre-made event action classes to use with EventHook.
- Rubygame::EventTriggers module.
Has several pre-made event trigger classes to use with EventHook.
- Added Rubygame.enable_key_repeat and Rubygame.disable_key_repeat.

=== Fixes
- Fixed: EventQueue#peek_each didn't yield any events.
- Fixed: Segfault in extract_rgba_u8_as_u8() on x86_64 systems.
Thanks to ElCuGo for this fix!
- Fixed: Several "cast from pointer" warnings on x86_64 systems.
- Fixed: Build system didn't correctly compile with debug symbols
when using "debug" option.
- Fixed: Surface#get_at didn't work correctly for 8-bit Surfaces.
- Fixed: Ftor.new_from_to would always complain about "wrong number
of arguments". Thanks to atiaxi for this fix!
=== Other Stuff
