Spyral

======



Spyral is a library/engine for developing 2D games in Python 2.X, with a focus on rapid development and clean design. Any system that runs Pygame should be able to run Spyral. Instead of ``import pygame``, you'll just use ``import spyral`` instead.



Spyral was specifically designed for developing `XO laptop `_ games. Spyral's main source of documentation can be found at the Platipy project, which documents Spyral in the context of a university course for which it was developed. `Visit the Platipy Project `_



What does Spyral offer?

-----------------------



* **Scenes and Sprites** : Scenes are stack-based containers for Sprites that make it easy to structure your game between different screens and levels.

* **Views** : Easily manipulate visual properties of collections of Sprites at the same time.

* **Rects and Vec2Ds** : Convenient container classes for managing two-tuples (think points) and four-tuples (think rectangles).

* **Improved support for Images** : No more fussing with Surfaces, just create Images (with a fluent interface!) and assign them.

* **Animations** : Animate properties of Sprites like the position, the image, visibility, or anything you need!

* **Event handling** : A sophisticated event delegator let's you register symbolic event names with functions, greatly enhancing the clarity of your code.

* **Forms and Widgets** : Need a button? Text input? Sophisticated tabbing? All our batteries are included!

* **Concurrency (Actors)** : Simple but incredibly powerful parallelism with a single MixIn - give each object it's own ``main`` function!

* **Styling** : Separate out content from your code with Styling.

* **Pythonic interface** : We tried to make things fun and easy for you, the developer.

* Plus other goodies like **Collision Handling**, **Layering**, **Game Clocks**, and more!



Pre-requisites

--------------



* `Pygame `_

* `Parsley `_

* `Greenlets `_ (optional, if you want to use the powerful Actors feature for multi-processing)



Examples

--------



* `skel.py `_ : A simple starting point for a new Spyral-based program, with a custom Scene. If you're not developing for the XO, this is a good starting point.

* `events.py `_ : Demonstration of registering keyboard and mouse events.

* `fonts.py `_ : Demonstration of a couple properties of fonts, and how to get text on the screen.

* `forms.py `_ : Demonstration of the Forms feature, including buttons and text inputs.

* `style.py `_ : Demonstration of using Style files to separate code from content.

* `concurrent.py `_ : Demonstration of the excellent Actors mixin, which allows quick and easy concurrency (requires greenlets). Press any key to step through it.

* `cursors.py `_ : Demosntration of the cursors presently supported in Spyral through Pygame. Press the left mouse button to step through them.

* `collisions.py `_ : Demonstration of two objects bouncing off each other.

* `animations.py `_ : Demonstration of the various kinds of Animations supported by Spyral. Use ``Space`` to walk through the steps.

* `view.py `_ : Demonstration of the functionality of Views, which allow Sprites to be manipulated in groups. Use ``Space`` to walk through the steps.

* `minimal.py `_ : The simplest possible Spyral program with no custom functionality. Not recommended, simply here to show off the simplicity.

* `artifical_events.py `_ : An example showing off how to mock events, or send out your own custom ones.
