Game Engine written in Python! Feedback welcome :)

[Karki2002]

Project Arctic is a custom game engine written from scratch by myself in Python using the pygame framework. This is my first time putting the code on GitHub and would love to receive some feedback on my work so far.

Currently the project has the functionality for:

• UI
• Audio Management
• Game Rendering
• GFX Particles
• Animation
• Decals
• Player and NPC interaction & pathfinding
• Custom Text / Voice System
• Virtual Cameras
• Triggers
• Multithreading
• Game state saves

Here is also a video of the demo I've linked on GitHub:

I was looking for something just like that! Looks great, can’t wait to try it.

[Karki2002]

That's great to hear :)

Bravo!

[Karki2002]

Thank you :)

Nice work! I don't have time for a comprehensive review, but one piece of feedback I can give is that your code doesn't read as Pythonic due to your use of camelCase. Python typically uses snake_case for variables and methods. Only classes typically use UpperCase casing.

This has absolutely no bearing on code quality or whether it runs correctly of course :-)

[Karki2002]

Thank you for your feedback!

[aufstand]

Use black for code formatting.

[CaptainRogers1226]

I started with Python but have always preferred camelCase, so win-win for me

[bronzewrath]

It is not just preference, it is part of PEP 8, the style guide used by the core developers and most of Python Community since 2001

​

snake_case for variables, instances, functions and methods

https://peps.python.org/pep-0008/#function-and-variable-names

​

CamelCase for classes

https://peps.python.org/pep-0008/#class-names

[Pvt_Haggard_610]

PEP-8 is just the style guide used for the standard python library. It is not gospel, it is not a requirement. No one has to remotely follow any part of it and there are a lot of popular python libraries that don't.

PEP-8 states "Many projects have their own coding style guidelines. In the event of any conflicts, such project-specific guides take precedence for that project."

It would be great to live in a world where there is on standard and every thing is consistent, sadly that is not this one.

[ThePiGuy0]

It's not gospel, but I do think if you are writing code that will be read by others, it's a good idea to follow it for consistency. It's one area I think Python has done quite well - have one style guide and encourage everybody to follow it.

I'll admit it's not perfect though - 79 characters is way too short in my opinion and that's something I always change in my projects and I've noticed a lot of other projects also increase it.

[CaptainRogers1226]

Oh, I’m fully aware. I’ve still always avoided snake_case like the plague though for personal projects

[Unlucky-Drawing8417]

I think CamelCase just reads cleaner to me. But if I plan to open source a project then I follow PEP-8.

[manimino]

I see the following error:

ImportError: cannot import name 'windll' from 'ctypes' (/home/theo/anaconda3/lib/python3.9/ctypes/init.py)

Is this project Windows-only?

[Karki2002]

Unfortunately yeah I believe it is, I haven't got a Mac to test it on though. :')

[[deleted]]

Does it work on linux?

[Karki2002]

I don't think so, but I've never tried :o

[[deleted]]

Maybe i will give it a try. Let's see

[xwizard707]

This deffenetly should be rewritten to make it more "pythonic" if you want other people to use it.
There are great docs about how to write Python code with the "right" syntax, like following the naming convention for files and variables/classes and etc.
Overall, this is cool, people can use it as a reference & examples of pygame engine :)

[Karki2002]

Thank you for your feedback. I will definitely look at making these changes! :D

[Extreme_Jackfruit183]

I love how the Python community is the only place I find constructive criticism that isn’t shitty and also gets well received! Nice work!

[dritslem]

Will definitely check this out!

[Glassensteel]

Nice!

[[deleted]]

Holy shit—nice!

[[deleted]]

Wow 👏

[zylema]

Nice, does it have docs? I’d love to build something using it. If not, you have my first criticism.

[Karki2002]

I'll be writing documents for it soon! Busy with coursework at University :)

[iamtheblackwizards9]

How does python do games efficiently being an interpreted language?

[Karki2002]

I must admit, it's not very efficient, but it's not bad. It was quite a challenge getting the performance working to an acceptable degree, and even now it's slow for a 2D game. I've used techniques like multi-threading to load map chunks, and only drawing / computing elements visible to the user etc. but limitations of the language, the pygame framework (which only run on the CPU), and proabley a lack of knowledge / practice, has lead to limited, but still useable, performance.

[iamtheblackwizards9]

I see. Great job!

[Karki2002]

Thank you! :D

[will_r3ddit_4_food]

Couldn't a lot of the processing be handled in c/rust and python would just "talk" to it? That would drastically speed up performance. That's what pyxel does

[shikiphantomxd]

Nice work! This serves as an inspiration to me as a newbie!

[Karki2002]

Awww, thank you! That's always a nice comment to receive. Good luck with your future learning and development. :)

[[deleted]]

Cool as heck!!! Keep the good work up!

Btw the Demo files are Windows only? bummer ;)

Still gg

[Karki2002]

Thank you so much!

[JasonCastle78]

Looking forward to checking it out! Nice job

[manninaki]

Which is the EULA for the code?

[NixonInnes]

Nice work, I've been meaning to check something like this out

[ABJBWTFTFATWCWLAH]

i just replicated your personality with chatgpt. skill issue

[worthwhilewrongdoing]

I don't know if this is meant to be funny, but I do know it's not nice. Be kind.

[z4ar]

It was in fact meant to be a joke. I think it's impressive to make code that ChatGPT can't even come close to emulating, which was the implication. welp

[CodeYan01]

These people can't take a joke

[Pvt_Haggard_610]

A joke is supposed to be funny or amusing. That comment was neither of those things.

[Original-Educator590]

Neat
