Rabbyt 0.8

A fast 2D sprite engine using OpenGL

Rabbyt is a sprite library for Python with game development in mind. It has two goals:

1. Be fast, without sacrificing ease of use.

2. Be easy to use, without sacrificing speed.

For a quick rundown on the current features see the website.

You can find the reference documentation here.

Changelog

Version 0.8

• The anims module has been rewritten with various new functionality, including:

  • You can now use anims with your own classes by subclassing Animable.

  • Added ease, ease_in, and ease_out anims.

  • Added support for chaining anims sequentially without using a scheduler.

  • AnimPointer added for reading from a memory address.

  • start and end argments for lerp etc. can now be anims.

• Added aabb_collide() function for doing bounding box collision.

• Removed the chipmunkglue module – it’s no longer needed for integrating with chipmunk. (See the example for the new way to do it using AnimPointer.)

• __import__() is now used for importing pyglet and pygame, so blacklists aren’t needed for tools like py2exe.

• Deprecated init_display function.

• Deprecated fonts module and vertexarrays module.

• Windows binaries are finally compiled with -O3. (I found the troublesome optimization.)

Version 0.7.6

• Added pyglet_load_texture for using pyglet instead of pygame. (Which one to use is autodetected.)

• Added Sprite.texture property, which accepts pyglet textures as well as filenames.

• Assigning a 12-tuple to Sprite.tex_shape is now converted from the format used by pyglet’s tex_coords texture attribute.

• Added Quad class, to make Sprite.shape and Sprite.tex_shape nicer.

• Added a workaround to make setuptools work with Pyrex 0.9.6.3.

• Added collide_single() function for finding collisions between a group and a single object.

• Fixed a bug where the time arguments in lerp were converted to ints.

• Removed deprecated physics module.

• Various other bugfixes.

Version 0.7.5

• New (alpha) Array classes.

• Fixed a segmentation fault due to weakrefs. (Sprite instances are no longer weakrefable.)

• Fixed sine interpolation being cosine interpolation :-P

• Added an example showing different interpolators.

• Added a flags keyword argument to init_display()

Version 0.7

• License changed to MIT.

• Added add_time() function.

• Time is stored internally as float instead of int. This allows for optionally using seconds instead of milliseconds.

• Added exponential, cosine, and sine interpolation.

• Documented rabbyt.anims quite a bit better.

• Forced Pyrex version 0.9.5 or greater, to prevent segfaults when using weakrefs. (It still can be compiled without pyrex.)

• Added more hacks for building on MacOS. Hopefully it’ll all go smooth now.

• Deprecated the Basic1 and Basic2 physics classes.

• HTML documentation is now included in the source distribution.

• Added missing documentation for VertexArray.texture_id.

Version 0.6

• Sprites can be scaled independently on their x and y axes.

• Added left, right, top, and bottom properties to Sprite.

• Fixed bug with some sprites being drawn upside-down when rotated.

• Fixed c, pyx, and pxd files being installed.

• Added a small function for integrating with the chipmunk/pymunk physics lib.

Version 0.0.5

• c source files are included, so Pyrex is not needed for building.

• Renamed the DV* classes to Anim*. (This is mostly internal and shouldn’t affect anyone.)

• MANY fixes and improvements to font rendering. (As in, it’s actually useful now!)

• Lots of docstrings added and improved.

• pygame_load_texture() now takes filter and mipmap arguments, which are passed on to load_texture().

Version 0.0.4

• Fixed compiling on MS Windows.

• Added some simple helpers for physics simulation.

• Moved all non-rendering code out of Sprite and into BaseSprite.

• Added font rendering support.

• Using color data in VertexArray rendering is now optional.

• VertexArray can now optionally bind a texture before rendering.

• Fixed a bug with VertexArray barfing when not given all the data for a vertex, instead of using defaults.

• Fixed a segfault when trying to load a texture before initializing the OpenGL context.

• Switched DVProxy and DVPyFunc to not cache by default. (Premature optimization is the root of all evil.)

• All examples now respond to window events nicely.

Version 0.0.3

• Added DVProxy and DVPyFunc classes. (Assigning a function to a sprite property creates a DVPyFunc transparently.)

• Added basic arithmetic operations for DV classes.

• Added Sprite.attrgetter() for super fast property access.

• Changed rabbyt.collisions.rdc() to not return groups with only one object.

• Added a number of introductory examples, showing the basic features.

Version 0.0.2

• Added vertex array rendering.

• Added collision detection.

• Lots of docstrings added/improved.

• Added rgb property to Sprite.

Version 0.0.1

• Initial release!
