Documentation for the PyDraw Turtle Extension

I - Capabilities and installation:

• Primitives(basic shapes): Squares, Circles, Triangles, and more, with their geometrical operations(area, perrimeter, etc)
• Custom shapes(via Vertex): Since PyDraw is based on the Vertex(basic x and y coodronates), you can make Polygons(with an unlimited nr of Vertexes), or an VertexSquare(an square made of vertexes)
• Motion, basic physics and collisions: The Vertex also helps with collisions, making every shape you do colide(of course, only moveable ones). You just define a shape, then you can move/rotate it or resize it!
• Keyboard Input: The library supports listening for keyboard input, allowing you to create interactive applications.
• Sound: The library also has a sound module that can play WAV files natively, and can decode and play other formats with FFmpeg installed.
• Fast updates: i am updating this library quite often! Especially bugfixes, my ahh can't make some nice code. Bugfixes will be part of most updates, so you can enjoy the smoothest, most stable experience! also we have issues so you can report bugs/suggestions there.

II - Installation

1. Via .url: Open the latest release, run the .url file and run the command from the site.
2. Via pip: run pip install pydraw-turtle, and pip install --upgrade pydraw-turtle for updating.

III - How2Use:

1. Shapes and their initialisations(one with ※ can be used with the Motion class):

In Sketchable, all shapes rely on the crucial Vertex. It is an uni-dimensional imaginary dot with an set of coordonates, from where all primitives are based! And in version 1.3.5, the Cluster has been added(and the list specifies what shapes are Cluster-compatible) that is an array of Vertex elements. The methods Cluster has are:

• from_list(list[Vertex]) - Converts an List full of vertexes into an Cluster
• add(v: Vertex) - Adds an Vertex
• remove(index: int) - Removes an Vertex from an index.
• pop(index: int) - Removes and returns an Vertex from an index.
• shift_to(index: int, vx: float, vy: float) and shift_by(same arguments - Moves to/by an Vertex from an index)

List of shapes and their initialisations:

• ※Line: line = Line(v1: Vertex, v2: Vertex/vertexes: Cluster)
• ※Vertex: vertex = Vertex(x: float, y: float)
• Circle: circle = Circle(center: Vertex, radius: float)
• ※Triangle: triangle = Triangle(v1: Vertex, v2: Vertex, v3: Vertex/vertexes: Cluster)
• ※Square: square = Square(side: int)
• ※(formerly VertexSquare)CustomSquare: vsquare = CustomSquare(v1: Vertex, v2: Vertex, v3: Vertex, v4: Vertex/vertexes: Cluster)
• Elipse: elipse = Elipse(center: Vertex, a: float, b: float) (has been depricated and removed prior to v1.3.5, because its lowk useless.)
• ※(formerly RegularPolygon)SidePolygon(n-sided shape): rpoly = SidePolygon(sides: int, side_lenght: float)
• ※(formerly Polygon)Mesh: poly = Mesh(vertecies: list/vertecies: Cluster) (make a list full of vertecies)

3. Importing:

You can import all the things Sketchable has by writing from pydraw import * (not avabile for versions prior to 1.3.2) If your version is 1.3.1, then write from pydraw import <what component you would want> And if your version is prior to 1.3.1, write from core import <what component you would want to import>

4. Movement:

PyDraw also suports movement, using the Motion class. To initialise the Motion class with an shape that is Movable, do: mov = Motion(shape, pen, vx, vy, colidable, CanExitWindow)

What they mean:

• shape - Any shape that is Moveable.

• pen: PyPen - An PyPen instance.

• vx: float and vy: float - The initial coordonates.

• colidable: List - An list of shapes that the current shape CAN colide(if you don't set it, it will default to None).

• CanExitWindow: Bool - If the shape colides with the window corner.

• For 1.3.1 and above: Use the Motion class, with the functions:

• move_to(vx: float, vy: float);

• move_by(vx: float, vy: float);

• set_velocity(vx: float, vy: float);

• accelerate(ax: float, ay: float);

• stop();

• check_edge_collision();

• is_on_screen();

• update().

Example code:

from pydraw import *

pen = PyPen("square chaos")
pen.initialise("white", 2, Speed.INSTANT, "black")

# ── squares ─────────────────────────────

s1 = Square(50)
s1.move_to(-100, -50)

s2 = Square(40)
s2.move_to(80, 60)

s3 = Square(70)
s3.move_to(0, 0)

# ── motion ──────────────────────────────

m1 = Motion(s1, pen, vx=3, vy=2, CanExitWindow=False)
m2 = Motion(s2, pen, vx=-2, vy=3.5, CanExitWindow=False)
m3 = Motion(s3, pen, vx=1.5, vy=-2.5, CanExitWindow=False)

# ── loop ────────────────────────────────

while True:
    pen.clear()

    pen.draw(s1,color="white",fill=True)
    pen.draw(s2,color="red",fill=True)
    pen.draw(s3,color="blue",fill=True)

    m1.update()
    m2.update()
    m3.update()

• For version 1.2.0 use the Moveable class, that has the same movement commands as Motion, but whiout the collision stuff, and of course, whiout updating(you need to do it manually via pen.clear() ).

Example code:

import os
import sys
from core import PyPen, Square, Triangle, Vertex, Moveable
from turtle import *
import time

pen = PyPen("dvd!")

pen.initialise("black", 1, 1)

cube = Square(60).move_to(100, 100)

dx, dy = 3, 2  # velocity (speed in x and y)

while True:
    pen.clear()

    # move cube
    cube.move_by(dx, dy)

    x, y = cube.position
    size = cube.side

    # screen bounds (you may tweak these depending on your window)
    left, right = -395, 395
    bottom, top = -330, 330

    # bounce logic
    if x < left or x + size > right:
        dx *= -1

    if y < bottom or y + size > top:
        dy *= -1

    pen.draw(cube, color="purple", fill=True)

    pen.screen.update()
    time.sleep(0.01)

IV - Sound:

PyDraw has a sound module, that can play WAV files natively, and can decode and play other formats with FFmpeg installed. You can use the Speakers class to play audio files. Just create an instance of Speakers with the path to your audio file, and call the play() method to play it. If your file is not a WAV file, you can call the decode() method first with the appropriate file type (e.g., "mp3", "ogg", etc.) to decode it into memory before playing.

Example code:

from pydraw import Speakers
speaker = Speakers("path/to/your/audiofile.mp3")
speaker.decode("mp3")
speaker.play()

V - Keyboard input[REMADE IN 1.3.7]:

PyDraw also has a keyboard module that allows you to listen/simulate to keyboard input. You can use the Keyboard class to listen for key presses. Just create an instance of Keyboard, and call the start_listening() method to start listening for keyboard input. You can also specify a callback function that will be called whenever a key is pressed.

Example code:

from pydraw import Keyboard
kb = Keyboard()

kb.is_key_pressed('esc').
kb.simulate_key_press('l')

• Also in v1.3.7, it got reworked to be both easier, but it now has the ability to simulate key presses. Both Mouse and Keyboard are in externals.py, and were written entirely by me!

VI - Mouse input[NEW IN 1.3.7]:

Now, PyDraw can record mouse input, simulate and listen to! Yes, the mouse coordonates are not relative to the turtle canvas, but it will be changed in the near future. after all, its W.I.P.

from pydraw import Mouse MouseBtns

mickey_mouse = Mouse()

while True:
    if mickey_mouse.isKeyClicked(MouseBtns.MIDDLE):
        print("damn bro after 1 day it finally works(yay)")

VII - Contribuiting and reporting bugs:

You can tell me what issues PyDraw has(because i don't test it too often), by going into the issues section of GitHub. Also, you can suggest me some new ideas there too. Forking is allowed, and you can fork freely, and even merge with the main repo. But if you make your own fork, be sure to give credit.

For this project i used the folowing OSS python libaries:

• Mouse
• Keyboard
• Pynput
• Simpleaudio (so don't DMCA me)
