pyunity's Introduction

PyUnity

Version 0.9.0 (in development)

PyUnity is a pure Python 3D Game Engine that was inspired by the structure of the Unity Game Engine. It aims to be as close as possible to Unity itself. This does not mean that PyUnity are bindings for the UnityEngine. However, this project has been made to facilitate any programmer, beginner or advanced, novice or veteran.

Disclaimer

As we have said above, this is not a set of bindings for the UnityEngine, but a pure Python library to aid in making 3D games in Python.

Installing

To install PyUnity for Linux distributions based on Ubuntu or Debian, use:

> pip3 install pyunity

To install PyUnity for other operating systems, use:

> pip install pyunity

Alternatively, you can clone the repository to build the package from source. The latest stable version is on the master branch and you can build as follows:

> git clone https://github.com/pyunity/pyunity
> git checkout master
> pip install .

The latest unstable version is on the develop branch which is the default branch. These builds are sometimes broken, so use at your own risk.

> git clone https://github.com/pyunity/pyunity
> pip install .

Its only dependencies are PyOpenGL, PySDL2, Pillow and PyGLM. Microsoft Visual C++ Build Tools are required on Windows for building yourself, but it can be disabled by setting the cython environment variable to 0, at the cost of being less optimized. GLFW can be optionally installed if you would like to use the GLFW window provider.

Links

For more information check out the API documentation. There we offer some tutorials on the basics of PyUnity, as well as all modules and utility functions that come with it. Examples are located at subfolders in pyunity/examples so do be sure to check them out as a starting point.

If you would like to contribute, please first see the contributing guidelines, check out the latest issues and then make a pull request.

Removing wild card (star) imports from files

Package data not included in wheel distribution

When built with bdist_wheel, all data files are not included. However, they are specified in setup.py.

[FEATURE] Resource handling and updating

Is your feature request related to a problem? Please describe.
Currently resources are dynamically found and only specific to the default ones provided by PyUnity, however if this is to become a standalone then said resources would be located differently. The current method of project loading only facilitates loading Asset files and doesn't have an interface for other file creations, such as config files or caches.

Describe the solution you'd like
A resource management system extending resources.py that also ties into the Project class.

Describe alternatives you've considered
Something similar to what Unity does, which is to bundle all the assets into a single compressed file that is distributed with the rest of the executable.

Additional context
This could also be useful in a PyUnity editor for when assets are modified, renamed etc. It also needs to take into account any project UUIDs it has to modify.

Clean stub files up and have automated checks

Specs (if you need):

OS: Windows 7 SP 1
Processor: Intel core i3 (x86)

Standardize API and use deprecations

Functions are constantly being renamed, changed etc and it's better to have a constant API that contains deprecations which notify the user when certain functions will no longer be used.

Additional context

Could be caused by using a terminated display but in pyunity/window/providers/window.py eglInitialize is called every time the window provider is instantiated. Similar issues also happen when using 32-bit python on 64-bit machine.

Convert stubs to inline type hints

The current approach makes it hard to maintain the project's types since the docstrings and stub files has to be in sync so I think the project should convert to inline type hints as defined in PEP 448 and note that a py.typed file will need to be added to /pyunity for PEP 561.

Since pyunity only supports Python3.6+ there will be no compatibility issues what's however.

I would like to know your opinion on this :)

Broken

Importing is broken, meshes are broken, setup.py is broken, compiling is broken, everything is broken. I need some time to fix it all.

[FEATURE] `Config` class that is set per project

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]

Instead of having global variables under pyunity/config.py, using a class that can be modified is more portable. This way we can separate flags and actual configs, whereas right now config.audio can be modified.

Describe the solution you'd like
A clear and concise description of what you want to happen.

Config class created that can be loaded and saved from the .pyunity file in projects

[FEATURE] Move main loop to SceneManager, or have a custom main loop runner

Is your feature request related to a problem? Please describe.
A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
The main loop code in the window providers is almost exactly the same thing: run some init, create a clock, infinite loop, quit etc. but it's hard to create something like VSync that can be toggled on and off. This really shouldn't be handled by the window providers.

Describe the solution you'd like
A clear and concise description of what you want to happen.
The main loop code should be either in SceneManager.__loadScene or (more preferably) another ABCMeta that can be subclassed and implemented, given an update function and set to chug along nicely.

Memory leaks

Sometimes MemoryError is encountered when copying the scene at runtime, especially with shaders and skyboxes duplicated (which they aren't meant to be).

[OBSERVATION] Cool idea, but the name will likely get C&D'd....

Cool idea for a project :) I suspect that as far as the name there are two situations:

no-one is using your project, and it sits below the radar, and Unity themselves don't notice, or do anything
your project starts to become popular. I suspect your name will then get cease and desisted, by Unity, at that point

I suppose you could just change the name at that point, but, might be as easy to just change the name now? (e.g. Mono, which Unity uses, didn't call themselves "Linux .Net Framework", they called themselves "mono", and everyone knew that it was a cross platform version of the windows .net framework).

this would also avoid having to state twice, in the first two paragraphs of your front page, that pyunity is not a wrapper around unity :)

(And it's natural to assume pyunity is a wrapper. My pytorch project, https://github.com/hughperkins/pytorch (which predates the Facebook pytorch by a year or two), was a wrapper around Facebook's lua torch)

Use `importlib.resources` instead of `file`

For PyUnity to be importable from a zip or egg, __file__ is disallowed. importlib.resources solves this with context managers such as importlib.resources.path that use pathlib, which requires #33 to be implemented too. PyInstaller would work much better and possibly the one-file bundler that I made could find resources better.

Another approach is to use a custom file finder, which internally uses importlib. This makes it easier to translate what is already being used to the new custom file finder which would have its own submodule. Hopefully it would not depend on anything else (like pyunity.Logger does right now) and then it could be loaded by itself without loading the entire PyUnity module. (This isn't final however, just an idea.)

Python 3.8 wheel is a bit broken:

Better tests

The tests in tests.py have not been changed for about 6 months and codecov depressingly says 41% coverage. One problem with testing is that on headless servers, window testing is not the easiest but the new EGL window provider should fix that (if I can make it find libEGL.so). Another problem is how to test if the rendering is correct, but I think that won't need to be included.

Replace `os.path` with `pathlib` functions

pathlib is available as part of the Python standard library, and takes a more OOP-based approach for path manipulation. It is also less clunky and results in neater code.

RenderTarget.canvas nested rendering

If RenderTarget.canvas is true, it may try to render itself in PreRender. Whether this is wanted or not, there needs to be a limit to the depth of recursion.

pyunity.errors.PyUnityException: Cannot find file: C:\Users\D\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\pyunity\examples\example8\explode.ogg

It is caused by the lack of an else statement for checking if the file exists. Also, the OGG file does not get included in the source and wheels.

[FEATURE] Support saving of lists and dicts in a formatted way, including other `SavesProjectID` or `Asset` instances

Is your feature request related to a problem? Please describe.
When saving a Scene, SavedAttributes can only be saved properly if they are one of the following types: str, int, float, SavesProjectID (including Asset), Vector, Quaternion, RGB, HSV. However, it is also useful to support saving lists or dicts of these types, which could even support nesting.

Describe the solution you'd like
Such a format would be similar to YAML, with a few differences: the list format would have a different prefix other than - , the dict keys would be any of the above types properly formatted (maybe apart from the floating-point classes since they would rarely match) and indents would be 4 spaces instead of 2.

Describe alternatives you've considered
Currently, the SavableStruct has a similar format but does not support nesting.

Additional context
This would make Button be able to save the kwargs argument in the Scene file.
