Pygame's Performance - What You Need to Know

[@DaFluffyPotato]

All gameplay footage shown in the background is from my own games. They're all open source (at least the ones that are released projects): dafluffypotato.itch.io/ For those of you who are saying I’m wrong about SDL. Read the docs for the update from 1 to 2. It *says* it added hardware acceleration. SDL2 is very different from the SDL Pygame originally used (and I mentioned that in the video). SDL2 adds hardware acceleration and Pygame 2 will give access to that functionality. Pygame was created in 2000 and the development stalled for a long period of time, so it was never updated to use SDL2. Pygame 2 is a huge improvement over 1.9.x.

Small tip for pygame performance is to prerender images, if you´re drawing shapes and lines, draw it on a surface on load and then paint that surface on screen every frame, it will be a lot faster then drawing lines every frame... this is only for the case the lines aren´t moving relative to one another, because if not, it won´t make much sense to do that

[@nathanlamaire]

A lot of programmers don't know about this, which is ironic since even the old days of game programming this technique is heavily used for optimisation since Assembly alone did not help.

[@badjano]

@@nathanlamaire Yeah, I thought "baking" was a pretty well known process, but it´s not common to see people using it more often. It´s amazing how much you can precalculate using only textures in a shader

precache everything, use memory pools. Don't create or destroy objects in your game loop because that run the garbage collection.

@@oscartriano7262 Could you explain the concept briefly? Let's assume I have an enemy that shoots stuff at the player; how would I not create a new bullet object every time he shoots and destroy that object when it hits something?

@@Milkymalk Use flags, like "used" so if a bullet collides with an enemy or something set its flag to "false". Here you dont destroy or create an object, just reuse them.

[@Orionhart]

You may not have heard of it, but there was a game engine developed using Python called Zero Engine, which was a proprietary engine used and created by DigiPen Institute of Technology whom I worked for and went to tech classes at. It was pretty alright. I don't remember too much, and I believe it was either discontinued or is simply no longer in use as many of the classes teach Unity instead.

[@prometheus9096]

Cython is also perfect to optimize your games, :) and it's wonderfully easy. Cython translates your Python code to C. For a beginner it is as easy as just compile a pure python file with Cython. This alone can increase your execution speed by 2 - 5 times! You can then start to slowly add C-Types and functions. Cython in fact is so good that it beat most code written directly in C, at least if you are just an average programmer.

[@ralfwright]

Please explain? How can python code (but translated to C) beat C itself? Shouldn't the language itself always run faster than when it is being translated to from another language, or at least run the same because they are translating to the same thing?

[@prometheus9096]

@@ralfwright C itself dose run faster. Please read the sentence as is: Cython in fact is so good that it beat most code written directly in C, *at least if you are just an average programmer* C just don't magically runs fast if you write a mess of a code and writing good C code is very hard. Most average programmers might see that their Cython--Code runs faster than their C code. However a skilled C programmer will write faster code than Cython.

@@ralfwright not an expert on this, but i think i know what's up. compilers are pretty smart these days and here we are talking about average programmers. an average programmer might not be able to write a highly efficient c code, but he can write a pretty good python code. the compiler on the other hand is designed to translate that python code to a c code in the most efficient way, so at the end the translated code might be better than a c code written by an average programmer.

Honestly.

It manages to get that beginner friendly rapid code development down, while still being a fairly high performance statically typed language and yes I am a little biased, cause it is similar to Pascal mixed with Python. Bite me for likeing Pascal I guess XD. SDL2 does already have a wrapper in nim for those who are wondering.

Worrying about whether your tools are going to eventually give you performance problems and researching potential performance issues is a satisfying alternative to doing the much, much harder work of designing and building a fun game. If you have a demo of a fun platformer but some SDL FFI issue is affecting framerates, it would be more straightforward to port that to C++ and eliminate the issue than to have a super efficient game engine but no game and have to design a fun, original platformer that feels really good to play.

@DaFluffyPotato Curious what your thoughts on Pyglet are? How you feel it compares, etc.

[@undofix]

SDL is cool for its simplicity but it's strange to see this library in use for something other than just create context for the OpenGL, the Vulcan, etc. It is more designed to process input and work with audio. P.S. I meant that pygame is great but I think pure SDL was not the best idea to make such game libraries.

[@dimitribobkov-rolandez5729]

Nowadays, SDL2 is used for windowing and input for games (if you're willing to write the renderer in OpenGL or Vulkan), but I've seen people use SDL2 functions (which are usually just OpenGL calls) for things like game jams.

[@cpK054L]

Curious as to why you are using pygame, and what appears to be pygame1 without using any Opengl rendering. I hear pyglet has faster framerate without really changing anything. Also pygame can render opengl which allows you to offload atleast updating the screen which id assume would be a performance gain. You have pygame create a headless surface essentially and then have opengl render. The issue I am having is framerate drops pretty quickly when the camera needs to move, or when the scenes get large. I know you implemented a chunk system, but im just curious as to why you are sticking with pygame 1 and without pyopengl

@@DaFluffyPotato Oh, I don't disagree. I am saying that you can use pygame as the core and easily do the performance critical parts (like shaders or 3d rendering) also in 'Python' while still using pygame.

I just wrote my first game in pygame and the only problem I have is that the keyboard scanning for player input seems extremely slow. it is like having 'sticky' keys.

[@leobozkir5425]

Can you share the code?

[@thinkingspace3438]

1- be sure to collect the inputs correctly, there's a key pressed event and a key unleashed event 2- don't tick the line that gets the inputs, it's a newb mistake

[@Kyu-us6xu]

1:12 guys what game is this i can't find out

[@DaFluffyPotato]

It’s a game I’m working on

[@MacronLacrom]

1) Pygame graphics use the CPU instead of the GPU because its SDL (PC's with weak GPU) 2) People don't write fast code so the games they make are slow

Is pygame powerful enough to make a Sonic CD Remake.

[@ArguetaLab]

Do you have any tutorials of pymunk?

[@DaFluffyPotato]

Nope. I don’t know it well enough to do that at the moment. The documentation will do the trick though

[@ArguetaLab]

@@DaFluffyPotato ok! Thank you! I am having fun watching your videos 😁

[@dhdhdudshdhd1041]

Is there a game engine made in pygame? And if there isn’t, why not?

[@pissmilker2313]

Pygame is slow but at the point you reach its limits your scope might be more suitable for for a native language anyways.

[@jxmmybeats8130]

Can you use pygame to make iOS and Android app ??

[@thinkingspace3438]

for android yes

[@bhangrafan4480]

C++ and C are compiled languages, but python is interpreted, surely this affects its speed? I'm no expert, I don't really understand why once source code has been written in a Python interpreter, where it is easy to test, it can't be put through a 'Python Compiler' to create a high speed executable file.

[@IPlayWithFire135]

Isn't that basically what happens when you have the final product? You make an executable file.

[@bhangrafan4480]

@@IPlayWithFire135 Hi, that's what I'm trying to find out, because in the past (I'm old) interpreted languages were translated into machine code at run time. (I've been out of computing for a while, I'm trying to do a bit again) There is also an issue of portability I am trying to find out about. C executable files were portable, because they were in machine readable instructions so the computer did not need to 'know' the language. Thanks.

Python 3.11 and future versions are also getting faster

you are making me want to try some python.

I think they referenced it with c++ it can go as high as 5000 fps
