Rabbyt is a fast 2d sprite library for Python.
Sets how coordinates map to the screen.
viewport gives the screen coordinates that will be drawn to. It should be in either the form (width, height) or (left, top, right, bottom)
projection gives the sprite coordinates that will be mapped to the screen coordinates given by viewport. It too should be in one of the two forms accepted by viewport. If projection is not given, it will default to the width and height of viewport. If only the width and height are given, (0, 0) will be the center point.
Sets a few of the OpenGL attributes that sprites expect.
Unless you know what you are doing, you should call this at least once before rendering any sprites. (It is called automatically in rabbyt.init_display())
Clear the screen to a background color.
Returns the OpenGL vendor string. Returns None if there is no context.
Renders a list of sprites.
Since this function is implemented in Pyrex, it should be a little faster than looping through the sprites in Python.
load_texture(byte_string, size, type_='RGBA', filter=True, mipmap=True)
Load a texture and return it.
update_texture(texture_id, byte_string, size, type_='RGBA', filter=True, mipmap=True)
Update a texture with a different byte_string.
Unload a texture from memory.
Automatically chooses between pyglet and pygame for loading a texture.
If pyglet is importable and pyglet.gl.get_current_context() does not return None, pyglet will be used. Otherwise, pygame is used.
After this function is called the first time, it automatically calls set_load_texture_file_hook with the correct function, so there is no additional overhead.
This is the default function for loading textures.
Uses pyglet to load a texture from a file. The texture is cached.
(This is meant to be used with set_load_texture_file_hook.)
pygame_load_texture(filename, filter=True, mipmap=True) -> texture_id, size
Reads an image from a file and loads it as a texture. Pygame is used for reading the image.
If filename is a relative path, the working directory is searched first, then rabbyt.data_directory is searched for the file.
This sets the callback that is used to load a texture from a file. (It is called when you give a string for the first argument of Sprite.)
The default is rabbyt.autodetect_load_texture, which will smartly choose between using pyglet of pygame to load the file.
The callback should take the filename as a single argument, and return either a tuple of the form (texture_id, (width, height)) or any value suitable for assiging to Sprite.texture.
In an ongoing attempt at cleaning up rabbyt, init_display has been deprecated and will be removed in a future version. You can achive the same result by doing this:
pygame.init() pygame.display.set_mode(size, pygame.OPENGL | pygame.DOUBLEBUF) rabbyt.set_viewport(size) rabbyt.set_default_attribs()
