Goopylib is a simple-yet-powerful 2D graphics framework built on top of Tkinter capable of creating good-looking, modern GUIs, games, and animations.

This graphics library is built upon John Zelle's graphics.py package which he made for use with his textbook "Python Programming: An Introduction to Computer Science". Over the past 2 years, I have worked on editing this library to add more features to use with making my GUIs and games. My aim while editing was to create a powerful medium to enable me to create good-looking graphics within Python and I have spent a lot of time making sure this is the case. Thus, this is a very intuitive, simple to use package with the potential of growing into one of the best Python Graphics Libraries.

If you would want to contribute to this library by suggesting features, reporting bugs, or adding changes yourself, please do so. I would love it if you would use this library in your projects and do make sure to tell me about them!

Goopylib is also compatible with auto-py-to-exe also known as Pyinstaller. This compatibility mainly means that all paths to textures & sounds are automatically converted into the absolute paths which you don't have to worry about! This means that you will be able to convert applications written with goopylib into executables with, hopefully, no errors.

Installation

The Primary method to install this library is from PyPi via pip:

pip install goopylib

or

pip3 install goopylib

This will install Goopylib and all the requirements for it to run. You can then import the library as shown next.

An alternative method to use this library is very simple to use especially if you want access to the source code, all you need is the folder called 'goopylib' and the requirements. This just includes the Pillow (PIL) module which you can download individually.

Download the folder and place it wherever you want access to the library.

Then, simply import as so:

from goopylib.imports import *
# or
import goopylib as gp

The first allows you to import everything that is part of the library, but if you want only specific classes z& functions, read on.

Organization

Goopylib is organized into a few different files and depending on what you want to do, you can import these files. There are 5 subpackages in goopylib: objects, math, sound, physics, & applications.

To import these, type:

from goopylib.maths.py_bezier_curve import py_bezier_curve # The other modules are 'Interpolation', & 'BSpline'
# or
from goopylib.objects.Rectangle import Rectangle  # For a list of graphics objects, look at the documentation

To access elements of goopylib like the Point & GraphWin classes, Colours, etc. use this:

from goopylib.colours import *

from goopylib.Window import Window
from goopylib.Point import Point

Projects made using goopylib

I have not supplied the code for these projects because of their scale, but, if you want to look at example projects with code, open the Examples folder.

1. A Pac-Man Recreation

I worked on this as a school project and used the goopylib library to create fully functional Pac-Man Game! (and an arcade too!) Pac-Man runs around while the ghosts (all animated of course) chase after him! He must collect all the pellets and fruits to go on to the next level.

2. Multiplayer UNO

During the COVID-19 Pandemic, my friends and I often hopped on a call and played a few games together: one such, was UNO. But the app we used was very laggy and didn't really function well. So I took it upon myself to create a Multiplayer UNO game in 5 days or less - and I succeeded on day 6... "but day indices start at 0 so it was really the fifth day...".

The game allows 2-7 players to play together and the graphics animate the cards, rotate them randomly, make them travel to the centre (as opposed to just instantly moving there) and more.

Here is a screenshot of the game:

Avatar graphics are from freepik.com

3. WROS - Website Recipe Organization System

This was an application I created for my mother as part of a school project to help her organize recipes for her website. It was the largest GUI project I worked on with goopylib. It took 7 days to make and demonstrates how goopylib can be used to create proffessional appliations such as this one.

4. Activity Club Selection App

My school has these weekly activity clubs where we all go to well, do activities. And every year, we sign up for activities using a pen & paper. Writing down our choices, handing them over to our teachers and waiting for them to sort through hundreds of entries and assign everybody a club - but not this year. This year I made an activity club selection app using the goopylib library that would automatically do all this work for you!

Goopylib is compatible with auto-py-to-exe which means you can easily convert any program into a .exe file and mail it to anyone to use. Now mind you, this was made with an older version of goopylib so it did not contain lots of animations and visual feedback, but here is a screenshot anyways:

Documentation

There are plans to create a detailed documentation for this library both in the form of YouTube videos and a writen documentation which has begun at: https://github.com/BhavyeMathur/goopylib/wiki
