phoenyx 0.1.13

An engine for pygame

Phoenyx - Pygame Engine

Some simple classes in python that could make your life much simplier. Relies on the pygame draw engine, 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 class suitable for physics engines and mathematical drawings.

Please go and check pygame for their amazing work ! Additionnal kudos to Daniel Shiffman.

How to ?

Please refer to test.py on GitHub for a very simple but effective test file. You can now also read the helpme file for all available methods and obects.

from phoenyx import *

renderer: Renderer = Renderer(600, 600, "Perlin Noise Loop")

SHOWINFO = True
w = 10
noise = PerlinNoise(3, unbias=True)

def switch() -> None:
    global SHOWINFO
    SHOWINFO = not SHOWINFO

    global slider
    if slider.is_hidden:
        slider.reveal()
    else:
        slider.hide()

    global slider
    renderer.create_menu("debug panel",
                         background=False,

    renderer.no_stroke()
    renderer.text_size = 15
    renderer.text_color = "black"

    global slider, t_offset

    y_offset = 0
    for i in range(600 // w):
        x_offset = 0
        for j in range(600 // w):
            d = noise(x_offset, y_offset, t_offset)
            d = int((d+1) * 255 / 2)
            renderer.fill = d
            renderer.rect((i * w, j * w), w, w)
            x_offset += spacing
        y_offset += spacing

    t_offset += slider.value

    if SHOWINFO:
        renderer.text(10, 10, f"fps : {round(renderer.fps)}")


if __name__ == "__main__":
    renderer.run(draw, setup=setup)

Requirements

Obviously some distribution of python : python 3.9 or above is required.

You will also need pygame in order to use the Engine and numpy to use Vectors. Also if you are on Windows and numpy 1.19.4 happens not to work with the last Microsoft update, make sure to update the current distribution of numpy with pip install --upgrade numpy.

Licenses

Phoenyx is licensed under the GPLv3. See LICENSE for more details. Phoenyx also includes the following components from other open source projects (see LICENSES folder for more):

• numpy licensed under the BSD 3-Clause "New" or "Revised" License
• pygame licended under the GNU LGPL version 2.1

Changelog

Please refer to the Changelog file for more detail.

This updates covers rotating and scaling of the display. It is worth noting that unlinke Processing, these methods only apply to what has been drawn on the screen rather than what will be drawn. These two methods are relative to the center of the screen (rotation around the center of the window, and scale from the center).

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
• widgets, canvas
