Pygame Platformer Tutorial - Full Course

[@DaFluffyPotato]

Here's a tip: VSCode shows the current object and function I'm editing right under the file tabs, which can help you keep track of where I am at all times. Clarification: If you have larger entities, they need to look up a larger area of tiles around them for physics. I used a 3x3 table in the tutorial, but you may need a larger one for large entities. A 5x5 table would be every pair of numbers between -2 and 2. (3x3 is -1 to 1) As of the release of this tutorial, I'm still using Pygame CE. They've actually released another update since I started working on this video as well!

I love your work!! I love love love it, I study pygame for your videos and I try to improve every day! Could you put subtitles in this video of yours? I'm Brazilian and I don't understand your videos very well when they don't have subtitles

[@DaFluffyPotato]

@@herikgiammaria9961 I think KZbin may still be processing the automatic subtitles. There's no way I could write up manual subtitles for a 6 hour video though. I just do manual English ones for my scripted videos now since I can just put in the script. Also, I'm impressed that the automatic ones are useful since it often doesn't understand what I'm saying.

You are a wizard of using Pygame, your previous tutorials were amazing, and the amount you've been able to build up around the library is immensely impressive. Thank you for sharing your experience and insight to everyone

[@Z3gn1c]

Just finished this amazing tutorial, took me about 4 days though spent about 18hours on it. But it was worth every second! This is the first time I actually worked with Pygame, and after your tutorial, I definitely have quite a few ideas of what I can do on my own. Will be checking out your other tutorials as well. Thanks for some amazing content !

[@holon4662]

This tutorial is amazing. I am about 3 hours into it and my "selfmade" map editor is almost finished. That's the coolest thing I created in Python so far. Thank you so much for the excellent walk through for all the mechanics. It saves me several hours I would need to study and understand the Pygame library from the documentation.

[@pistondev2204]

true bro I am also grateful for him that we got these tutorials in youtube easily, imagine people making games in 2000s where these things didn't existed

[@emperor8716]

this is crazy. a tutorial from the actual best, i can't wait to do this.

[@nilusnilus6365]

wow i remember a few years ago following your platformer tutorial, very glad to see you continuing the series :D

[@VolarGorilla917]

Words cant describe how thankful I am for this dude. I love coding, and i also love playing video games. I wanted to get into game dev and i have made a few games and have worked with a few pathfinding algorithms (i implemented Dijkstra's GBFS and A* in snake and a cool little maze solver), I wanted to get into making better games, making platformers specifically. But I was never able to get past making a player move around, I'd always struggled with the scope of the project and the concepts of how to make my own tilemap / tile editor and I especially struggled with collisions using tiles. Ur a wizard dude, some of these solutions u came up with to the problems i struggled with are so simple. I really appreciate you making this long tutorial that explains all of the code and even the math, most tutorials dont bother explaining the math, they just say "oh this is just how you do this". They dont bother to explain what it is or how it can be applied, and that goes for all of the code. I love that you stopped, backed up for a second and explained the code, how you can change it, and several different applications for the code. Sorry for rambling dude im just really thankful.

[@DarkPlaysThings]

Thanks so much for the great tutorials! It’s awesome to see your thought processes and see how you make such high quality experiences using python!

[@ZaynBrando]

This is actually the best video i've ever seen that explains things very easily for a beginner and helped me understand the "WHY" behind every code. Thank you so much, subbed!

This guy has to go down in the books as the best Python game developer.

[@galaxybrainnews9772]

After the optimizations around 1:52:15 I adjusted the tilemap __init__ to add a million tiles in each direction instead of just 10. it took a while for the project to start but even with 2 million tiles loaded into the tilemap it was still buttery smooth once it got going! (Using python 3.12 and pygame ce as of 11/9/2023)

[@DaFluffyPotato]

Yep, that's expected. You can have some pretty massive worlds. Often times RAM will become an issue before CPU usage in those cases (provided you don't have too much on the screen at once).

[@lucaivaldi4520]

@@DaFluffyPotato I wonder if the optimization is more about not having to query the whole dict more than queuing a lot of draw calls. Of course premature optimization is the root of all evil and we should always benchmark before trying to optimize. I think the SDL library (and the backend it uses, Opengl, Metal, Vulkan..) will be more than happy to discard any draw call that draws off the screen, but there is the cost of querying the whole dictionary anyway, so your solution could cut the time spent there. Anyway, I'm not sure how much of an issue that could be. Anyway, this is only something I'm asking myself and your videos are super, thank you!

[@SagaContinu]

If anyone runs into an issue with their character falling through the floor: Collision detection is checking where you are located in the a grid system ---> that's what the tiles_around() function does. It uses the co-ordinates from the top left of your player image to workout where you are. If your player image is larger that the grid system it will only register that you are in the next grid section to update the collisions after you have fallen through the floor. Try checking from the center of the image instead. Or else you may need to do more than one check i.e. top left, bottom right. Or else increase the checking distance to include more tiles. Interesting way to do the collision detection though

[@HammouaI0I0I0]

how to do this btw

[@SagaContinu]

@@HammouaI0I0I0 Adjust tilemap.physics_rect_around() function to check from the center of the player instead of the top left player_loc = self.game.player.rect().center However, if the distance from the center of the image to the sides (right,left,top,bottom) is still greater than a tile width this won't work.

[@Programmer-Anchous]

This is the best pygame platformer tutorial I've ever seen! Thank you!

[@jumparoundtheatoms]

Awesome stuff you did sharing this , many thanks :) . One thing for those who made it to enemies :P : while DaFluffyPotato does mention and switches to off grid placement for the player ( and subsequent the enemies ), if one does place the spawners by accident on grid like me, extract will fail. This is because the spawners are not part of self.offgrid_tiles, but self.tilemap, and the loop in the extract function its done on the self.tilemap directly and not on a copy. Reckon by accident and the loop should be done on a copy to catch this cases.

[@Nolexes]

I totally overheard the offgrid part couldn't get my game running anymore and got different kind of errors trying to fix it so thanks for the comment. I bet it would have taken me ages to find this out on my own :D

I'm changing things around too as to really push myself to understand your code more thoroughly (for example I used a sprite sheet that needs coordinates instead of files for the Level Editor, which required a fair bit of tweaking across multiple files).

[@cursorop1716]

at 1:33:00 if you divide self.scroll by 30 then the camera follow up will be slow . If you jump from high distance your player will fall first and camera wouldn't be able to follow up player , so divide it by 20 so no matter how high you jump the camera will follow up player in slow manner but without losing its track .

@@DaFluffyPotato The video with the drawing was very well explained! I wish we could have seen more concepts in that format.For example , before coding certain topics such as camera movement ,and tiles creation, you often start explaining your thought process.

[@arbitervildred8999]

you can actually do something about that camera bug when it gets closer to it's target, I believe you can target more of a radius of 5-10 pixel from the player origins, so once it gets closer to the player it will stop trying to center it perfectly and avoid the bug (but of course, the player will be slightly offset by 5-ish pixels) OR when it gets to that 3-5 close pixels, suddenly speed the camera from 30 to 100 so it gets spot on in maximum 2 frames (about 1:35:50)

To All my fellow learners using MacOS at time stamp 2:37:03 for the level editor I had to use the "z" key for scrolling through the different variant types in a group instead of LSHIFT. Best I can tell is MacOS reserved certain key combos for other functionality and it overrides pygame-ce functions. There may be a more elegant solution but I simply used the "z" button which is right next to the shift key. I love my Macbook Pro but the more I get into this the more I see developing on MacOS kind of sucks. I am a total noob at this but now I understand why some things may only be developed for one or the other because of all of these little items like key combos.

Around 1:12:25 I ran into a problem where I wasn't able to print the tiles from around the player as they were falling, after downloading the code, comparing them side by side, copy and pasting over my own code with yours in some places to determine what was actually different, it turns out I had the "return" function on the wrong indent within tiles_around I would have never caught something like that on my own and could have been very frustrating to troubleshoot without the example code. Now I have another thing to add to my list of things to check if stuff doesn't work as it should and hopefully this problem wont catch me off guard next time. Just saying thank you and posting in case anyone else has a similar issue.

The camera offset (passed as offset there) is the top left corner of the "view" in the world's pixel coordinates. You perform an integer division by the tile size to get from pixels to tile coordinates so you can look up tiles based on the camera position.
