0.6 Beta 1

First beta of our Summer Solstice 2019 release.

Note that because of incompatibilities, PyGame 1 and Python 3.6 & 3.7 are the only supported versions. Neither Python 3.8 nor PyGame 2 are supported in this release. (This will hopefully be fixed for our Fall Equinox 2019 release, but its largely out of our hands.)

• Online docs! https://ppb.readthedocs.io/ (#195)
• Sprites can rotate (#214)
• An Idle event has been added, fired each iteration through the event loop (#221)

• A title argument has been added to ppb.run() (#258)
• ppb.make_engine() has been added to simplify customization (#255)
• GameEngine.loop_once() has been added to allow for external loops (#255)

Fixes since 0.5.1

• ppb.utils.LoggingMixin now works with subclasses (based on the file the calling code is in) (#202)
• StartScene no longer requires an empty kwargs when passed a scene class (#236)
• GameObjectCollection (and its subclass Scene) work correctly with subclasses of children (#241)

Version 0.5.1

Minor patch to keep changes to ppb-vector from breaking installs of ppb.

Version 0.5

We went for a smaller release, but we got a lot done for it only being
a few months. The most important bits are that all of the input events
are in! Some cool stuff includes sprites scaling automatically and a
new way to move between scenes that uses the event system. That means
the old method is officially deprecated.

New stuff:

• MouseButton events
• Key events
• Add a title to the game window
• Sprite scaling based on game unit size
• Keycodes flags
• New scene change mechanism that uses the event system

Changed stuff:

• Scene defaults are now class attributes
• Most Sprite defaults are now class attributes
• Flags can now be type hinted properly
• Scenes no longer infinitely respawn their child scenes if running is True.
• Fixed an issue with the frame being different dimensions to the viewport.
• Fixed a bug in the Camera.point_in_viewport function
• Default pixel ratio is now 64:1 (64 pixels to 1 game unit)
• New (better) run function
• Other type hinting fixes

Removed stuff:

• bb attribute removed from sprites

0.5.0rc3

Candidate 3. rc2 had a bug around defining size as a class attribute. rc1 was missing the systems subpackage.
