phoenyx 0.3.3
A drawing and physics engine for Pygame
Requires Python: >=3.9

# Phoenyx - Pygame Engine v0.3.3

Some simple classes in **python** that could make your life much easier. Relies on pygame, numpy and pymunk, based on the idea of the Processing language.

## What it does

This library allows you to create graphical components in **pygame** in a very few lines of code. It handles all color management, stroke weights and filling for you. It also provides a Vector and a SandBox wrapper class for **pymunk** suitable for physics engines and more mathematical drawings.

Please go and check [pygame](https://github.com/pygame/pygame.git) and [pymunk](https://github.com/viblo/pymunk.git) for their amazing work ! additional kudos to Daniel Shiffman.

## How to ?

Please refer to the [examples folder](examples/) on GitHub for very simple but effective test files. You can now also read the [helpme](helpme.md) file for all available methods and objects.

```py
from phoenyx import *
import random as rd

renderer: Renderer = Renderer(600, 600, "collision")
sandbox: SandBox = SandBox(renderer)

count = 0
fall = True


def revert() -> None:
    global fall
    fall = not fall


def clear() -> None:
    sandbox.clear()
    init()


def init() -> None:
    for i in range(11):
        for j in range(6):
            sandbox.add_ball(60*i + 30 * (j%2), 100 + 60*j, 1, 15, elasticity=.99, is_static=True)

    sandbox.add_segment((0, 600), (600, 600), 1, 5, is_static=True)
    for i in range(11):
        sandbox.add_segment((60 * i, 600), (60 * i, 500), 1, 5, is_static=True)


def setup() -> None:
    global fall
    init()
    renderer.create_menu("options", toggle=revert, clear=clear)

    renderer.set_background(51)
    renderer.text_size = 15


def draw() -> None:
    global count, fall
    sandbox.step(iter=1)
    sandbox.draw()
    renderer.text(10, 10, f"fps : {round(renderer.fps)}")

    count += 1
    if count >= 30:
        count = 0
        if fall:
            sandbox.add_ball(rd.randint(299, 301), 0, 1, 10, elasticity=.8)


if __name__ == "__main__":
    renderer.run()

```

## Requirements

Obviously some distribution of python : ``python 3.9`` or above is required.

You will also need ``pygame`` in order to use the Renderer, ``numpy`` to use Vectors math and ``pymunk`` to enable physics. To upgrade to a more recent version of any lib, run ``pip install --upgrade ...``. Requirements will automatically be met with pip when installing phoenyx.

## Licenses

## Changelog

Please refer to [the changelog file](changelog.md) for the full history.

Migrating to the pymunk library for better physics (and complete support of chapes, joints and constraints). Circles, Segments and Polygons have been implemented (either dynamic or static ones). Pin joints, slide joints and segment extension have followed. Some fixes have been added to the Renderer as well as support for images manipulation.

<details>
    <summary> v0.3.3: do a barrel roll (click to expand) </summary>

* you can get rid of a SandBox shape if you want to
* new methods for the Renderer to handle images and font changes
* new ScrollBar thing (type ``help(phoenyx.ScrollBar)`` to learn more)
* ScrollBar affects the Renderer view field of the main window
* actual animation for the ScrollBar item
* huge typo and format fix accross the entire repo (pray for the reorganisation)
* somehow reorganisation worked around pymunk errors when closing main window
* new method to handle the Renderer pixel array
* new example file, water ripple (f slow)
* finally worked around slicing vectors, functionnal getitem setitem delitem methods
* new methods for the Renderer to draw anti-aliased lines

</details>

## TODOs

* ~~option to hide buttons and sliders or to draw them only when needed~~
* ~~option of alts drawing methods for buttons~~
* ~~keyboard integration~~
* ~~scrollbars and side menus~~
* ~~interractive drawing~~
* ~~physics Sandbox~~
* ~~more physics happening for bodies~~
* forms and confirm boxes, events
* integrate some utility functions (based on the example files)
* 2d game oriented approach, player, compas, cells, map, ...
* get rid of the renderer and sandbox objects and bring all methods into main scope (not guaranteed)
* if, big if, there is a v2, 3D rendering
