- I'm a C++ developer, but I tried to learn Python by making a game with the Pygame graphics library for the Pygame Community New Years Jam. In 2 days, I was able to put together a simple game (Flappy Bird meets Cookie Clicker?), and I learned a lot along the way!

--Descriptive Description--
I thought it would be fun to try to learn Python by challenging myself to create a video game in under 48 hours (2 days) using the Pygame graphics library. Yes, I know Python probably isn’t the best language for making a real-time game, but it’s definitely fast enough for my simple 2D games, like the one I created with SDL2 in 48 hours for the 2020 GMTK Game Jam.
For this devlog challenge, I found a week-long game jam: the PyGame Community New Years Jam, but I decided to shorten it to 2 days and give myself only 48 hours to make a game.
First things first, I had to set everything up, which actually ended up being pretty easy. I ran the Python installer for Windows, added the Python extension to VS Code, and installed Pygame through pip. Now we can get into the actual game-making! I decided to try to make a game similar to Flappy Bird, but vertical-you would collect coffee beans to upgrade stats like flap strength and speed in order to fly as high as possible.
I found a Pygame example that showed me how to draw a square to the screen. Next was gravity, which is very simple for a game like this. Every frame, I add a fixed value to a y velocity variable, then I add the y velocity to a y position variable, and I draw the square at that y position. Then, I figured out how keyboard input worked in Pygame, and made it so when you press a key, the velocity variable is set to a negative fixed amount, allowing the blue square to flap. I also gave the player an x velocity that flips if its x position is less than 0 or greater than the screen width. Now the core mechanic of the game is done-you can flap and bounce off the walls.
I created graphics for the player and coffee bean collectibles, and created a “camera” that follows the player-basically I just offset everything on the screen by the player’s y position. For the coffee bean functionality, I made a Collectible class with Vector2 to store its position, and wrote a function for rectangle collisions. I draw a list of beans above the player, and if any bean collides with the player I reset its position to a random range above the player. And with that, the main game is finished.
I finished off the project by adding UI and other visuals, like a colorful background, and creating a shop (using bean currency) with three upgrades-one that increases your flap strength, one that makes you faster, and one that makes more coffee bean collectibles spawn. And that's where the challenge ended! This was learning Python in 48 hours with Pygame. - Věda a technologie

Well... The game jam WAS called New Years game jam...

Because you learn best with a clear goal mind.

Meanwhile he learns python in just a few hours and builds a game, while for me it took me 3 days to install and setup python
he probably has foundation already since he knows basically the most of other prog languages like Java.

I just finished my first-semester learning python at uni and this is far beyond anything I have made. I think it's really cool and stuff like this inspires me to keep learning!
That's awesome! Keep it up
Did you go into uni with no/little coding experience?
@@useranonymous3354 doesn't matter (most of the time, if you're asking for uni resources check with the unis you aim for)
Going from C++ to Python is like Picasso deciding to make potato prints 🤣
@@bytekast Yet the things you do in c++ can be done by kids in python.
Just because you use a bloated old language doesn't mean you're a better programmer. Most experienced python programmers could learn c++ in a few days if they wanted to.
@@onebigsnowball Yet most of the kids wouldn't be able to code any good game wdym???
@@bytekast python is being used because of the following reasons:
1) the development speed it brings
2) it's interpreted, meaning a project doesn't take 40 minutes to compile each time you make a small change
3) the amount of ready to use packages. Each package may save you 5 hours of brainstorming and coding.
4) How easy it is to visualize data
5) the clarity of code that it has. Other developer may glance over a piece of code, and correctly guess its purpose.
In more low level languages, all you see is quadrillions of pointers, addresses, garbage collection mechanisms, and it takes more code and way more time to understand the purpose of the code.
Granted, some of this depends on the developer - how well can he code self-documented code, how well can he refactor, how consistent are his conventions throughout the codebase, does he prioritize following the patterns over speed of development etc. But all of this takes time, and anyway...
...done is better than perfect
@@bytekast and yeah python shouldn't be used in gamedev, unless it's simple 2d games and/or for educational purposes.
With python you're more focused on logic, the important algorithm itself. In C level languages you're constantly worrying about not causing a memory leak and implementing features that should be already available by default. Even such simple things/patterns as singletons
@@bytekast lol why do you like your own comments. And yeah I agree, but I think you misunderstood me as a python fanboy. No, i just listed why python is preferred in many tasks. I can write as much about advantages of C level languages. I did that because in the beginning of this reply section you seemed very blind and all you worried about was performance (speed of execution), but not speed of development and production. C like languages were developed when computers RAM was in the kilobyte range, and CPU clocks were very low as well. Of course you would prioritize performance.
But nowadays, it's not always the most important thing. What brings more money quicker is used where it's possible. Of it's a performance dependent task, like heavy games, then of course you'll use c++
Everyone:
Yeah imma try to learn python like this year but it might take longer
Polymars:
Yeeeaaah 2 days sounds pretty legit not gonna lie
As a pygame learner, this guy is REALLY quick. Idk the help he got from his fans, but this man has talent
@@mariaenigma4294 look at the code itself, it's a really messy code that doesn't even have proper function distribution and most of it is literally just using pygame functions and basic python syntax, most of what he did are stuff he already knew from previous languages.
@illusionist 😂, I was wondering how the hell did he learnt the basics of python and then learned a module then made a game within 2 days. Now I understood how he did that
@illusionist oh thanks bro, I have been to coding for 2-3 years, I was not consistent 😅, now I have learnt pygame module, currently I'm making games😀
I took me three months
You're truely inspiring me on trying to take up learning a coding language as well. Even though you struggled at first you got an amazing result tbf
You will make it far in programming for sure , I’m a CS major in college and I really wish that I had started in high school. No doubt your first couple years of classes will be super easy if you plan on going to college
I feel like I didn't get programming until super recently (I'm a junior in college) and I started senior year of hs. It really takes a while to get going depending on how fast or slow of a learner you are (I'm in the slow learner camp bt dubs).
He's a good autodidact, and every knowledge about programming is online. I think it will be far more efficient, cheaper and funnier for him to skip college altogether. He can already find a job easily and continue to learn from there. What do you think about it?
@@chlodowigi1833 You are right, he will be able to get a job. But what happens to his youth and personal development? Going to university was some of the best years I've had in terms of personal and social development. It really got me out of my shell and made me so much more sure of myself.
I studied engineering and it taught me a lot about managing large projects, which some of my colleagues who are software devs lack.
@@chlodowigi1833 Computer science is a LOT more than just programming
Why not wish you learned it in middle school
It would be pretty interesting seeing you learn different programming languages and making games out of them. Can't wait to see what you do next!

Wow, he's actually alive, thought he was going to leave for another few months.
The line "for bean in beans" just gets me
same
It's normal in Python. Dave Rhodes even had a minirant of how he can't say "for request in requests" without confusing everyone (requests is a very popular Python library for HTTP). :-D Also, you can't say "for i in is" since "is" is a keyword in Python, but that's another problem. :-]
This is the first dev video I’ve seen that was educational funny and entertaining keep up the good work!
You are awesome! I’m learning Python yet but your videos help me so much!! Thank you ❤️🔥

I literally had an ICT exam today that had Python in it, and now this vid is in my feed (Got a full mark obvi), and I loved this challenge!
CZcams recommended me this 3 years later even though I've been watching Dani since like forever
LOL this is exactly what I went through the past two days. I was trying to create a ray marching algorithm from scratch, and settled on using pygame despite never having used python before. I figured it would be a good way to learn the basics. Almost _exactly_ the same as what you did.
I started with Python and then switched to C++. God, that was a pain, but in the end it worked out.
Damn same but i started in Javascript then Python and then C++
same but javascript > python > c#
@@TheCubicLog no...... (maybe as long as you dont use it on electron apps)
i went from python to js to java, was a relatively easy transition tbh
Went from C++ to C# to Python. It was a ride lol.
I love the little detail in the thumbnail, showing the semi-column(tottaly butchered that ik) is an error since you dont have to end with it in python
Huuuuge thhhhhx to you guy and CZcams recs for this video, cuz it gave me such a boost of motivation that I ... I am just... Yah, opening a new pet project!

oh.... OH.
Did the same thing except I learned Godot (coming from Pygame) in under 48 hours for a jam. Made a video and everything. lol
It really is a great way to learn stuff quickly.
Oh wow didn’t expect to see you here
Woah
Hi Dafluffypotato, I am your fan
when i tried godot i was confused so much but when pygame it was easier
Yo it's that guy!
the thumbnail his hilarious XD the fact that there's an error bar around the semicolon really encapsulates the pain of the python language. and whitespace... oh god...
Missed opportunity to code this caffeine-based game in JAVA.
Yes
As a barista, I approve of the name flappuccino 😂👍
Oh man. I learned this as my first programming language and learnt it for like 8-9 months and never finished a game. I gave up and am learning Godot now. At first it was very complicated because I was used to just coding everything. Anyways... now I saw this video of you making a good game with pygame in 48 hours or so without having any experience with Python and I couldn't make an average game after all those months...
Ooooooof!
Don't compare yourself. He is someone who is already proficient in C++, which is a much harder language than Python and already being good with one language, means that it is way easier to switch to another. So he isn't *really* just learning it in 2 days, he has an entire background of knowledge to lean on.
I wanted to learn python but my goal was to make games, a lot of years ago I downloaded GM to make an undertale fangame but when I was learning python I found out that the only game engine in pygame and, well, it didn't have GM's convenience of literally everything, I don't even know if you could make a complex game in python like a whole adventure rpg which I wanted to make (not small-scale, a full game) so I just went to game maker 2 which is now free and haven't made progress in learning python
Wow, this was a lot of fun to watch! Feeling inspired to try making my own game :’)
Go for it! And thanks for the awesome music :)

Believe me.
Its pain on certain languages.
The fun parts are fun, but people don't pay high salaries for stuff that's fun.
what you want to do is not focus on the end product that being the game but on the process of making it itself and I also suggest you sometimes try other projects as well and to use languages like c Cpp and such sorry I cannot use punctuation
you better still be c++ gang (or ban from codergopher++)

I'd use a quadsirandom sequence to spawn the beans to ensure they aren't overlapping if you have so many.
Thriving under self imposed stress is actually really accurate description for me too... That's very eye opening!

That's because he has previous experience with programming. A lot of programming concepts and general syntax are similar between languages, so it's much easier to learn a language if you already know another one.
@@nikkiofthevalley + the maths. The maths he showed wasn't as intuitive to simply come by in a week or two, it must have been a pretty good maths foundation.
So he had all the tools, maths, graphics, UI design, programming and I'm new here but most likely game dev experience as well.
A programming language is just a toolkit, you may get a hammer and screwdriver in one kit, or a hammer and a plier in another, but it's mostly the same, it's the knowledge of how to use the hammer and where that matters. Don't feel bad, because you too can be a better carpenter if you keep at it :)

Pretty cool! I think it's a nice basic game!
Bro you're insane! Love your vids, quick question: What helped you learn how to program the best?
Polymars: how do I declare a variable on python
Me, knowing you don’t declare variables in python: I’m 4 parallel universes ahead of you
Yeah... Imagine what he'd have done if he _understood_ Python's object model. :-P
Looks great for a first game in Pygame, and welcome to Python! I made a game with Pygame recently for the Wowie! Jam, and it turned out alright.
If you're still used to declaring variable types, you can supply a type annotation (VSCode should help force type checks as well): variable: str = "Hello, world!" I do this a lot since I'm used to type-checking from Swift. (edit: fixed formatting)
Thanks! Cool to see people using Pygame :)
