#A "toolbox" library used by other polygonal libraries (core)



## Documentation

-    API [http://polygonal.github.com/doc/core/](http://polygonal.github.com/doc/core/)



## Packages

The library includes the following packages:



### `event`

- A library for handling events, with focus on boilerplate reduction and performance.

- See [A fast notification system for event-driven design](http://lab.polygonal.de/?p=2548).

- See [The Observer pattern](http://en.wikipedia.org/wiki/Observer_pattern)



### `fmt`

- Various helper functions for formatting numbers and objects.

- Supports [sprintf](http://www.cplusplus.com/reference/clibrary/cstdio/sprintf/) syntax. See [Using sprintf with Haxe](http://lab.polygonal.de/?p=1939).



### `io`

- A fast [Base64](http://en.wikipedia.org/wiki/Base64) encoder.

- Resource loading / mass loader (_flash only_)



### `log`

- A simple logging framework.



### `macro`

- A bunch of basic macros for generating classes at compile-time.



### `math`

- Math helper functions.

- Fast 2D/3D vector and matrix math.

- Pseudorandom number generators ([Park-Miller-Carta](http://lab.polygonal.de/?p=162), MT19937)

- [Trigonometric approximations](http://lab.polygonal.de/?p=205).



### `sys`

- Entity framework for component based architectures.



### `time`

- Time-based updates, timeline, timed execution.



### `tween`

- A tweening framework.



### `util`

- Misc utility functions.



## Installation

Install [Haxe](http://haxe.org/download) and run `$ haxelib install polygonal-core` from the console.

This installs the polygonal-core library hosted on [lib.haxe.org](http://lib.haxe.org/p/polygonal-core), which always mirrors the git master branch. From now on just compile with `$ haxe ... -lib polygonal-core`.

If you want to test the latest beta build, you should pull the dev branch and add the src folder to the classpath via `$ haxe ... -cp src`.



## Changelog



### 1.01 (released 2012-11-15)



* fixed: Mathematics.floor(), ceil(), fwrap() for neko, don't use Std.int() for cpp

* modified: keep dispatching Timebase updates when calling MainLoop.pause()

* modified: make de.polygonal.core.time.Delay cancelable

* added: math.RootSolver class

* modified: Entity: pass message sender when sending messages

* fixed: keep existing fields in macro.Version

* added: Entity.is() and Entity.isAny()

* fixed: minor tweening fixes, added tweening examples

* modified: Observable: consider group id in event filtering, use 30 bits for neko

* added: TimelineListener as an alternative to TimelineEvent

* modified: optimized tweening performance

* added: Entity.iterator() to iterate over all children (non-recursive)

* modified: merge Observable.bindMulti() and Observable.bind() into Observable.bind(), fix group filtering
