[potent ice]

No worries. Can poke you when I make it public

From a higher level perspective it's not that hard to understand. Ignore all the rendering stuff. We have a world with chunks and they have data.

Going into details on the rendering can make you snowblind 😄

[dawn quiver]

what kind of data strucutres do you use for your blocks?

do you have some sort of id system?

and do you have an editor or gui interface?

[potent ice]

A block is a list of bytes (65k of them). 0 is air and everything else is some kind of solid block

There are no fancy bells and whistles like editors and whatnot

[dawn quiver]

oh so the blocks dont have properties really. The block is determined by what byte combination it has.

or wait

maybe i ot that wrong

[potent ice]

chunk.data[x + y * 16 + z // 16] something like that to look up a block in chunk coordinates I think

The block data is generated on the gpu and just read quickly into python as raw bytes

[dawn quiver]

what im saying is can you compose a block type from the bytes like adding properties or are each byte combination a unique block unrelated to similar byte combinations.

i guess thats not as important

as it can be easily changed

[potent ice]

They are a unique block in the chunk. There are no properties currently

Blocks can have static properties per type stored externally, but not for each individual one for now

We don't want the game to use 10GB memory 🙂

[dawn quiver]

-._.- the biggest thing ive done is tetris

id love to make something like metriod though

metroid is my favorite game. I tried making something like it in minecraft

[potent ice]

The video I posted consists of 16.777.216 blocks btw

[dawn quiver]

nice

pretty good. Probably becuase there isnt dynamic about it so its not hard for the computer or gpu to handle that

have you got loading and unloading chunks working?

[potent ice]

Nope, but all the parts needed to do it is there

[dawn quiver]

can you perform movement operations on the gpu to speed up performance?

[potent ice]

What kind of movement?

[dawn quiver]

or is that more suited for the cpu. The movement of entities like in minecraft

[potent ice]

The camera does all the world movement on the gpu, yes. That's the least of worries.

[dawn quiver]

my brother says he wants to make an rpg.

he likes paper mario and bug fables.

he also said he would be interested in making an ascii art rpg. So i might show him pygcurses

[potent ice]

Could try to start some community game or something? Like always there is a problem with direction and what to actually make lol

[dawn quiver]

yeah thats a big problem im facing

like id like to program a game but its hard to think of the game to program

[potent ice]

Usually better to stick to small project. A simple idea.

[dawn quiver]

i think itd be fun to draw pixel art then have it go through a image to ascii art converter

and put that into the game

[potent ice]

hmm start by making some ascii converter?

It can be a challenge to make it fast, but at least it's a challenge

Sounds like you might be more like me. You enjoy maybe game systems more than making the actual games

You could look at arcade for example. Figure out what the library does. That will keep you busy for a while 😄

[dawn quiver]

yes exactly

i loved making tetris

and id love making a rpg with characters and level systems and battles

it all sounds fun to code

[potent ice]

yeah

Thought about doing something similar, but too many projects going on atm

I would just play around with pre-created sprites and tiles in Tiled editor and load that into arcade

[dawn quiver]

yeah ill remeber to try that.

but first im gonna see about pygcurse

i really want to make a turn base combat system

[potent ice]

ah right. That does remove the needs for fancy graphics 😉

[dawn quiver]

im gonna research some roguelikes and rpgs and make something.

and that will be the base i work from

at least ill be doing something. This is just a hobby.

thanks for the talk.

i wanted to show the 2nd game i made in 2 years but meh

[potent ice]

Like the automatic message says, you can paste the code into https://paste.pythondiscord.com/

Optionally you can put your game on github, gitlab or any other public code repository

[main cradle]

ok

Discord is only really able to deal with small code snippets, so showing a larger project cannot be done directly. At least not here on python discord.

how come theres not a lot of python game engines?

[snow hill]

Game engine, I don’t know, but in terms of 3D engine, Python has some rather nice piece of software…

ok thank you for the response :)

[dawn quiver]

can i create minecraft mods w/ python?

[gaunt monolith]

Minecraft is written in Java. You might be able to use Jython or something, but that'd really first require good knowledge of both Java and Python, it's probably not a good idea.

[snow hill]

I wonder what is the core of a Minecraft-like display algorithm…
I assume it’s not a naive approach using nested loops… probably something that takes advantage of the sparse nature of a voxel representation ?

[past quarry]

Is there a difference in coding language between Minecraft Bedrock and Minecraft Java?

[round obsidian]

I believe it uses "instancing"

@snow hill https://learnopengl.com/Advanced-OpenGL/Instancing

[snow hill]

aaah yeah

makes sense

didnt they remove that from blender?

[cold storm]

upbge is a fork where a friend of mine restored it

it's kept in sync with blender master

[ruby lion]

I'm getting weird rotation with rotozoom in pygame.
Any help would be appreciated.
Fixed, I forgot to recalculate the rectangle after rotation.

[potent ice]

@round obsidian The classic approach is doing chunk reduction on the CPU. It's relatively fast to loop thought 65k blocks in a chunk (classic minecraft) and only emit the visible faces. With instancing you just get too many polygons. You only emit the visible faces of a block and blocks and sides on the same plane gets merged into larger polygons. For example a 16 x 16 x 16 block of cobblestone can be reduced to 12 triangles just like a single block. Several chunks can be reduced into a single mesh as a "patch" to reduce the number of draw calls. There is a lot of other magic as well. A lot.

[maiden perch]

what

ty for the info

you pinged the wrong person though

l0l

[potent ice]

I definitely pinged the wrong person 😄

@round obsidian is the right person. Apologies 😄

Will do 20 pushups

I'm doing a simpler form of chunk reduction in my engine. It only currently looks at the north, south, east and west block deciding if faces should be emitted. This alone is a HUGE saver. I know minecraft also store metadata about each 16 x 16 x 16 area (spatial hash) so it could be used to determine of the area is even reachable discarding it completely.

It's too slow do do in python on main thread, but you can do it with multiprocessing and possibly cython. I just do it all in shaders because that's even faster (but it has limitations)

For example, It takes 0.2 to 0.5 seconds to generate a 16 x 16 x 256 x 16 x 16 world on the gpu. The python version I had used 1min 37s, Can probably make it faster with more creative use of numpy, but that also have its limitations

[stray kelp]

[willow canopy]

I k

[potent ice]

Are we staring an IDE/Editor war or something? 😉

[cold storm]

With BPY generating blocks I was able to get a block in 1 tick (16ms)

I started with a mesh that was full of blocks, sampled the center of each block, removed all faces for a block of it was not there, and then remove any faces that share a center

I swapped to blender geo nodes and was able to get that down quite a bit

[vestal ocean]

Hi

[autumn comet]

[snow nimbus]

I have a pygame related question

can i ask here

[cold storm]

https://tenor.com/view/monty-python-holy-grail-knight-death-bridge-gif-21185062

I don't know that

[potent ice]

Definitely starting to look like something

Added some basic physics to the voxel engine : https://www.youtube.com/watch?v=6G_1gybAP-U

It's drawing an outline of what chunk you are standing on. The world depth is insanely overkill when starting on layer 256 initially

[compact agate]

@potent ice maybe numba for numpy operations? for more speed

[potent ice]

Nah. It can be fast enough in pure python. Everything else in happening on the GPU anyway. Collision with box voxels are not that demanding.

[compact agate]

i know you can do numba stuff with the gpu, but looks very cool

[potent ice]

Numba doesn't fit my use case

I want to see what you can do only with shaders and pure python 🙂

[compact agate]

cool!

[potent ice]

I still have 9 more millisecond to do stuff (per frame)

[balmy quiver]

hi

could someone help me fix this

I don't know how to fix this

error that I don't know

[potent ice]

Would have to see more of the project to understand what is going on. You should have a button.py that contains a Button class. That's what it's looking for

[potent ice]

Made a complete mess, but at least removing blocks works and it's fast enough

[prime flicker]

How can I reduce lag in ursina

[cold storm]

einarf, you can use raycast to the bounding box per AABB / per chunk

and if it hits-> test vs more complete test (bvhtree?) -> no hit case to the next one,

in local space to the chunk

(so you don't have to go building a giant world bvhtree)

[dawn quiver]

@potent ice hey can you come to dm

[whole burrow]

I was thinking about teaching a small programming workshop for beginners and was wondering if using pygame is an ok idea to have students make small games over a couple of weeks. what do you guys think? I heard it's a huge pain to set up ...

[potent ice]

Keep things in public channels

[potent ice]

Yeah that's the plan for block selection. For collision it's easy enough to just look up blocks around the player.

The AABBs would just be aligned unit cubes anyway

[potent ice]

The fastest way just for box selection is probably reading the depth fragment at the cursor position (screen space) and convert that to world position. That will pretty much give me the exact box pointed at.

BUT... will need raycast anyway for other things.. so probably both

[potent ice]

You probably need to be a lot more specific here

[dawn quiver]

is unity game engine better or unreal for beginer?

[round obsidian]

I'm going to say your choice of engine is meaningless if you don't know programming yet, since they will be equally bewildering and intimidating

[dawn quiver]

well i meant i am just starting game development

[round obsidian]

how much programming experience do you already have, and with what languages?

[dawn quiver]

mainly with python

only

i am learning c

[round obsidian]

Unity uses C#, Unreal uses C++, and Unity is slightly more beginner-friendly

[dawn quiver]

oh ok

thank you so much!

[ionic pond]

hey, i have a pygame related question. I'm trying to make my first game (the pygame snake game). I am reading and comparing different code, but I'm trying to use the least exterior resources as possible to improve my understanding of game logic

I've gotten to the point where I have a purple square (my snake) that you can move around. if you go off screen, the game closes and there is a randomly generated red square (the apple/food) that pops up. I can't, for the life of me, figure out/understand how i can make my snake "eat" the block and expand itself

basically, the snake ignores the apple and crosses over it. I don't know what I need to make the snake able to "eat" the apple and (later) expand/increase its length

[round obsidian]

at each move, check to see if the head of the snake and any of the apples occupy the same space (collision detection)

[ionic pond]

thanks for the reply! I'm going over my lines of code rn, one by one, to make some changes

[dawn quiver]

hey so im new to pygame and i was making a tic tac toe game and im getting the error code 'ValueError: invalid color argument'

oh..

dont worry

got it now

[ionic pond]

Also, general question: Has pygame helped improve your general understanding of python, or do you guys simply learn pygame for fun?

[cold storm]

@dawn quiver

there is panda3d

pygame - upbge

pyopenGL

many ways to code in python

@ionic pond apply your python stuff to blender and it gives you super powers

upbge is a fork of blender + bge restored (a py game engine) using eevee render

100% open source / free

this is generated

hey guys i need help in #☕help-coffee

[cold storm]

with games?

[dawn quiver]

in #☕help-coffee

[cold storm]

than why not just ask here

-_-

0/

hi

[dawn quiver]

because thats what the help things for?

[cold storm]

people ask for game dev help in game dev area 😄

it makes more sense

(also the answers remain here in the searchable history)

[ionic pond]

usually the help servers are pretty flooded tbh

[cold storm]

so we can answer future questions before they are asked

[dawn quiver]

ok so this is my code
https://paste.pythondiscord.com/cujazaxani.yaml
and im getting this error AttributeError: module 'pygame.font' has no attribute 'render'

[cold storm]

WIN_IMAGE = font.render(WIN_TEXT, True, BLUE)

try above this

print(dir(font))

and see what methods it has

it's saying that the method you are calling does not exist

you should see what font has or if you are doing the right thing

[dawn quiver]

so put print(dir(font))

above WIN_IMAGE = font.render(WIN_TEXT, True, BLUE)

[ionic pond]

man, my code looks reallyyyy bad T__T, i still cant make the snake game work

[dawn quiver]

im still confused on what to do for my code

[ionic pond]

how did you copy/paste your code onto here?

[ionic pond]

and sorry i cant be of help since im still a newbie ://

https://paste.pythondiscord.com/zeliwuqaxi.yaml hopefully this works

[dawn quiver]

oh i fixed my code

[ionic pond]

this is a link for anyone who is interested in helping me fix my snake game

yayyyy

youre smartttt

im at school and im balancing my school work with my crappy snake game so its not going so well T__T

[dawn quiver]

aha

ill try see whats wrong

[ionic pond]

tbh, i think imma restart my entire code from scratch because it's THAT bad

so maybe i should do that after school??? Orrrr... i can try to sneak it in now

yeah, im restarting it >:-))

[round obsidian]

Colorful instructions

[ionic pond]

love the aesthetic

[dawn quiver]

wtf is that

whats it coded in

[round obsidian]

thanks!

[dawn quiver]

yo

so with game development

can u code games in more stuff besides pygame

like to make better games

[round obsidian]

@dawn quiver anything you learn in PyGame can be used to learn other things with other game development systems

the general principles are what's most important.

[dawn quiver]

what can u use to make 3d games

[dawn quiver]

like this

[cold storm]

upbge

this is coded in the fork of blender upbge

[dawn quiver]

alr i’ll try it out

[round obsidian]

I have never made 3D games

[dawn quiver]

are 3d games like very hard

compared to pygame shit

[round obsidian]

3D games are orders of magnitude more difficult than 2D games

[ionic pond]

i just realised that the problem with my snake game was that i accidentally had different block sizes for different loops T___T

AFTER ALL THIS TIME

thanks for the support here tbh

yall are cool

[cold storm]

https://www.youtube.com/watch?v=8Pk-V94h0t4

after you get to where you are really good in 3d @dawn quiver you are pretty much a rocket scientist

using vectors, matrices, converting equations into code etc

[dawn quiver]

3D is so confusing

imma stick with 2d xD

[ionic pond]

this is some next-level stuff O__o

it looks very cool though!

[cold storm]

start with 2d

fiddle with 3d

but blender = super powers because it's api is python based

upbge BGE code is py and BPY both work in game in realtime

[balmy elk]

hey, im trying to make a basic game using pygame and pymunk for physics. im at the stage where im spawning a bunch of rectangles in random positions...

i was wondering how i would make it so none of the rectangles overlapped

this is what im using for detecting the overlapping

but i get this error

[lyric lily]

Hello want to ask.. Im new in Python.. and I want to learn to create Software using Python... anyone can recommend me.. what is the best course i need to take to mastering Python?..

[potent ice]

Did you see the resources in #welcome ?

[potent ice]

Playing around with block removal profiling the bottlenecks. It can still be done a lot faster, but it's a start. Remember this is a 16 x 16 x 256 x 16 x 16 (16_777_216 block) world. It gets pretty heavy. https://youtu.be/fNjuZyTJytM?t=15

Still need to optimize if neighbor chunks needs to be updated or not. That alone will probably make it twice as fast in most cases + I'm using numpy for vector math (too slow). Numpy for lots of small independent 3-component vectors are not ideal. There are faster alternatives.

My respect for people making fast voxel engines have increased a lot in the process. It's a lot of work 😅

[normal silo]

https://github.com/Zuzu-Typ/PyGLM

[potent ice]

Yup. That's exactly the plan. Already porting most moderngl examples to that in a branch atm 🙂

[normal silo]

>>> import glm
>>> a = glm.vec3(1.0, 2.0, 3.0)
>>> a
vec3( 1, 2, 3 )
>>> import numpy as np
>>> b = np.array([1.0, 2.0, 3.0])
>>> b
array([1., 2., 3.])
>>> a + b
array([2., 4., 6.])
>>> 

[potent ice]

I am used to glm in C/C++ already. There was some issues early in pyglm 2.x related to buffer protocol that stalled the adoption

[normal silo]

Also recommend using PyPy instead of CPython.

[potent ice]

I'm sticking to CPython for now, but maybe later. (Problem with pyglm was PyBUF_SIMPLE support)

I don't think pypy is necessary quite yet. There is a lot of room for optimizations still.

[normal silo]

Yeah, but no reason not to really, as long as your current libs are supported which they prob. are.

[potent ice]

I want the project to be easy to install and run on an platform from source. Most of the heavy lifting are also done on the gpu.

There are some long term plans for this project that requires easy install / access and it's important that it can run on py3.6 -> 3.10

I also can't guarantee pypy support because I don't know what this will be mixed with eventually (by end user)

Collision checking doesn't really take much time at all even in cpython and I doubt a ray cast thought simple cube voxels with a limited range would be much of a problem. I can also reconstruct world position from the depth buffer to more or less get the exact block a player is pointing at

[normal silo]

I'm not exactly sure how the end user combing your code with theirs would make your code not work with pypy.

PyPy does not really require you to do anything special, you run the same script.

The only thing that prevents PyPy compatibility is some specific C extension stuff that is kind of rare.

(some C extensions do things that are actually bugs in CPython and PyPy fixed them, so if they use those bugs it won't be compatible)

[potent ice]

hmm I guess you have a point, but I don't really need it at the moment. At some later stage that could be the case

[normal silo]

Yeah you don't need it, but it's basically free speed.

[potent ice]

It runs smooth on my average laptop with AMD integrated. Also most of the work are done on the gpu. pypy won't make that go faster 🙂

[normal silo]

Yeah, just when you get to some code that actually needs to run on the CPU and is not something done with numpy.

And also not very small.

Like gameplay code.

(Ofc depends on type of game, but for many it's often the case because games are weird and need to do things that just require a bunch of conditions and specific code that would not really be done with numpy, the GPU, etc)

The type of stuff that can't be run in parallel at all because of tight coupling between systems.

But also it's python not C so kind of whatever. Just recommend PyPy, IMO should be the main implementation of python that's used (standard).

[potent ice]

Don't have any plans adding a lot of gameplay to be honest. It's more or less an experiment seeing what can can be done with the gpu and cpython. Might have to change that later of course. Could also do a C extension. That's what I do in most cases.

[normal silo]

The reason i'm in favor of just making python faster if even just a little is because i'm not a fan of having lots of dependencies in a project and "just write the slow parts in C" adds a lot of them, staying in pure python is nice, or in general any language hopping is always annoying.

[potent ice]

I'll at least give pypy a go at some point

[normal silo]

What makes it annoying is the need to sort of synchronize the two languages, if either of them updates.

[potent ice]

I don't mind C extensions. I'm so used to it

I can also cheat the GIL

[normal silo]

You have the extra work of maintaining the bindings and so people get generators, but generators are buggy and also need to be maintained and have different versions and stuff (it's also another thing that anybody working on the project has to learn).

PyPy is not way faster and it never will be because of python's design, but IMO it crosses that line were the language feels just fast enough to actually make things that require a bunch of looping and such like C# and Java and such. Not super fast, but just fast enough to actually make things.

Which is all I really want from a scripting language, fast enough and to start coding I just need to make a new file and run it, no setup, nice and lazy.

For many things python is already that, but it will never be that for everything unless it itself becomes faster to cover more cases.

[potent ice]

I'll give pypy a chance at least. I'll give you that, but pypy or C extension is far in the future for this project 😄

I should probably have tested pypy more anyway

[normal silo]

Yeah don't worry about it i'm ranting now. Anyway GL, it looks great.

[potent ice]

It's more than fine. Any input on optimizations are good

And yup. pyglm made collision checking 5-6 times faster \o/

[normal silo]

Yeah, my best advice for optimization is to do non-optimization, rather than worrying about timing the code and all that and going crazy, just make the CPU only do what it needs to do and not more. Like with pyglm instead of numpy. Numpy is more general and so it was making the CPU do more than it needed to.

Less general tends to equal faster (it's why high level abstract code tends to lead to slow programs nobody likes to use ("Enterprise")).

This is also why C is just straight up faster for everything, because you are not running an interpreter and just having the CPU do less work for the same result.

But you can still do this cutting down in Python or any other language.

And the second thing is to make use of all the hardware given (e.g. the GPU or the many cores in modern CPUs), but that comes after the cutting down which is much easier to do.

[potent ice]

I worked with C and rendering in the game industry for many years, so I definitely know

[normal silo]

Ah ok, yeah I don't doubt it then.

[potent ice]

Optimizing in python is weird. There is a lot of learn, so it's a challenge. For example : WeakSet is a terrible idea

[normal silo]

Graphics programmers are built different.

Every time I read a paper on some new graphics related thing I wonder if they are all overqualified for the job.

[potent ice]

Yeah. I have an unhealthy obsession with optimizations at times. We used to count cycles in inner loop in assembly making sure it was inside the cache.

I'm so outdated when it comes to anything after 2012

[normal silo]

Yeah i'm of the same breed. Trying to get MSVC to not spit out terrible assembly on Godbolt.

But I don't do any of that unless I really need to, modern computers are so fast that the just making it do only what it needs to route is often more than enough.

[potent ice]

and the evolution of compilers have made things a lot easier

More cache, cores and whatnot certainly doesn't hurt

[normal silo]

I mostly work in C, but since I work in ML now Python became something I had to learn and i'm glad I did because it lets me connect to the non-programmer scientific community, just wish PyPy was more popular. It's what most of them often want anyhow without even realizing it.

[potent ice]

ah right. Now the pypy thing makes sense 🙂

[cold storm]

upbge has NUMPY

and we have compute shader framework but I don't know how much is wrapped by gpu module right now

pypy is like a jit for python?

[tranquil girder]

Isn't pypy slower to start up? That's a pretty big downside considering CPython is pretty slow already

[gaunt monolith]

JITs are slower to start up, and consume a bit more memory. But the point of them is that after running for a bit, they find the code that's called frequently, and use data about the data types involved, most frequent code paths, etc to optimise that code into native versions on the fly.

[sterile berry]

Hi

[normal silo]

The first run of a function / iteration of a loop is slower, but still faster than cpython.

[proper peak]

it depends on what you use it for - for quick-running scripts pypy might be a bad idea, because the increased startup time will be more than the decreased runtime

[normal silo]

Don't except huge gains though.

[normal silo]

If you are not doing any looping yourself then you may as well use cpython. But if you are running something like a game which loops forever, it will matter.

[proper peak]

Yeah, I'm talking about applications like scripting, where the entire runtime of your program is like a second. There, pypy is a net negative.

[normal silo]

Yea pypy for me has about a half second of extra startup time, no matter the script.

The thing about pypy is that all you need to do is just run pypy instead of python or python3 (depending on which OS you are on), and it will almost always just work, so if you happen to have something that is getting kind of big, like a whole application rather than a script at this point, then you can just try pypy.

[normal silo]

Or from the pypy website:

There are two cases that you should be aware where PyPy will not be able to speed up your code:

    Short-running processes: if it doesn't run for at least a few seconds, then the JIT compiler won't have enough time to warm up.

    If all the time is spent in run-time libraries (i.e. in C functions), and not actually running Python code, the JIT compiler will not help.

*If for some reason you only want to use pypy and need faster startup times for short scripts, you can turn of the JIT compiler --jit off, then startup time (and run time) is about the same.

[cold storm]

https://www.youtube.com/watch?v=cse3PGsgBoc

I think JIT is faster than interperted

and compiled is faster than JIT

there is "Nuitka"

but I think that something using AI will come along

[normal silo]

Technically JIT can be faster than compiled but in practice not so much. The reason is that a JIT compiler could re-compile to a more optimized version by collecting run-time data.

[cold storm]

that can take py and spit out optimized assembly

like imagine a GAN that generates C* or even optimized assembly from py

and it tests 1000's of itterations per tick

and keeps the best one

[normal silo]

ML is not even close to generating good code. Despite the hype around the GPT code writers.

[cold storm]

training data would be input data would be unoptimized py and then hand written optimized code

for output

case by case with 1000's of cases

(I think this is why MS is after github)

[normal silo]

Yes, but why generate code when the entire program can be a neural network? It's even faster, and even more so with special hardware for neural networks.

[cold storm]

I think that there is a sort of GAN in humans

we generate and evaluate plans to see if they will meet a goal

but when we sleep, we optimize helper functions

[normal silo]

Let's move this to the data science room.

[dawn quiver]

hey so with unity

is it for ios only

or does it do android aswell

[potent ice]

Wrong discord server

[dawn quiver]

what?

[potent ice]

This is primarily a channel for discussing game development with python. Unity is kind of off topic here unless it has some useful parallels to python itself.

[potent ice]

renpy is based on pygame anyway 🙂

[glossy umbra]

Hi friends !

[deft linden]

Hi! How can I check if a circle is colliding a rect in Pygame?
I tried to use a Rect to follow the circle, but it only works with a small ball, but it doesn't for bigger ones

[glossy umbra]

@deft linden i have the same problema with my code

[deft linden]

oh really?

[glossy umbra]

Yes, but i do not know how I show my code to a little help

[deft linden]

I found an approach: Find all the points in the circle and check if that rect collide with that point

Um wait

I found a way

[deft linden]

By that approach, I just did the method in the wrong way

[proper peak]

Does pygame not have a function for that? Anyway, here's the general formula for checking the collisions of a rect and a circle (this example is from a Rust spatial partitioning library):

https://github.com/Uriopass/flat_spatial/blob/master/src/shape/circle.rs#L30-L35.

[frank field]

src/shape/circle.rs lines 30 to 35

    fn intersects(&self, b: AABB) -> bool {
        let x = self.center.x.min(b.ur.x).max(b.ll.x) - self.center.x;
        let y = self.center.y.min(b.ur.y).max(b.ll.y) - self.center.y;
        x * x + y * y < self.radius * self.radius
    }
}```

[proper peak]

the Python version would look like

def intersects(rect, circle) -> bool:
    x = max(min(circle.center.x, rect.upper_right.x), rect.lower_left.x) - circle.center.x;
    y = max(min(circle.center.y, rect.upper_right.y), rect.lower_left.y) - circle.center.y;
    return x**2 + y**2 < circle.radius**2

[deft linden]

[dawn quiver]

HELP ME WITH PYGAME PLSSSSS

[dawn quiver]

not bad uno

[lean cosmos]

@dawn quiver thanks coach

[cold storm]

@dawn quiver you can use py + blender ot generate content for unity

[potent ice]

You would normally do a ray cast to see if a line between the player and the target is blocked by something. You can either make that yourself or use pymunk

[potent ice]

Putting your code here makes it easier for us to understand what you are doing. https://paste.pythondiscord.com/

A screenshot is not very useful for someone wanting to help

[potent ice]

Just ask your question. That's the only way you might get an answer.

[dawn quiver]

https://paste.pythondiscord.com/xobahusiqe.py

ok

[potent ice]

What do you mean by "wait before it close"?

[dawn quiver]

i mean not close when the game end

[potent ice]

You can just add an input() at the end so the user have to press enter to exit?

If that is not enough you have to be more specific

[dawn quiver]

thx

i have a another problem i get 3 wrongs or goods

[potent ice]

You can instead refer to he line numbers of the code you shared. Screenshots are not useful in most cases

You have three if statements checking the result and printing stuff so it will definitely print 3 times

Option 1 is always the right answer?

If that is the case, the only checking you need to do is ```py
if Player == 1:
print("GOOD")
player_score += 1
else:
print("WRONG")

You also seems to use pycharm, so you can use the debugger to visuals step though your code seeing exactly what is happening

[dawn quiver]

yes

but it still dont work

[potent ice]

What does that mean?

Only you know how the game works. For me it looks fine except that you never set game_over to False

[dawn quiver]

how can i make that he pick a random thing

[potent ice]

I see you have already imported the random module

You can use random.randint to generate a random number

See : https://docs.python.org/3/library/random.html#random.randint

[dawn quiver]

thx

[dawn quiver]

the random.randint dont work

[potent ice]

Please stop using "don't work". You need to be more specific 🙂

!e
import random
print(random.randint(1, 3))

[frank field]

@potent ice :white_check_mark: Your eval job has completed with return code 0.

1

[potent ice]

It definitely works and it gave us the number 1 (this time)

You can show me how you changed the code and I can possibly help.

Make a new paste or just paste some code here

[cold storm]

was able to port a section of my py to GEONODES 😄

https://www.youtube.com/watch?v=OcKsmnJ8UTQ

[potent ice]

I think maybe 2 people here knows what geonodes are

Are you referring to the new Geometry Nodes recently added to blender?

[cold storm]

yeah

you can express some decent node groups now

it's still not 1 to 1 as useful as py

but it's like 250X faster or more

since it's blender, you can use py to programically create nodegraphs too

logic nodes addon for upbge writes py

so it can kinda go both ways

[elfin summit]

it only moves if it has to, to conserve resources

[ionic pond]

this looks really cool!

By the way, does anyone have any tips for making a dialogue/text-heavy game on pygame?

[normal silo]

Make the dialog good. Writing is hard. You are competing with books (making a game without competing with books is already hard).

Pick good fonts and make sure the font rendering is clean at multiple scales and DPI's.

[ionic pond]

Thanks, hehe. I'm just doing it for fun since I am learning python

im supposed to be doing schoolwork tbh T__T

but im trying to figure out how to make dialogue disappear without it overlapping and without using time. It's 2AM here so im 100% sure there's a simple solution im not considering

[dawn quiver]

sorry i'm not english

[dawn quiver]

how can i open a pygame window

[ionic pond]

First of all, Make sure you have pygame imported into your IDE (I use pycharm)
Then you need to set screen width and height and then you use pygame’s blit window feature

make sure to update display!
la#

If you don’t update the display, you’ll just get a black rectangle

Idk if that helps, I’m pretty new to Python

[dawn quiver]

i have that but how i can open it

[inner wigeon]

You mean open the pygame window? It should open on its own when you run your program.

[dawn quiver]

I get this

[inner wigeon]

You need to install pygame. Go to your windows search bar, type "cmd" then click on command prompt. In the command prompt, type "pip install pygame".

[dawn quiver]

i have pygame

i download pygame but i still get it

[snow hill]

maybe you have more than one instance of Python installed on your machine

or maybe you need to grant to virtual env to access to your python modules

what happens if you open a command prompt, sa @inner wigeon said, and enter "pip install pygame" ? 🙂

[dawn quiver]

its sy i have it

say

[tranquil girder]

what's you IDE? you should follow you IDE's guide for using python with it

[snow hill]

looks like @dawn quiver is using Pycharm

[timid hemlock]

Do you use some sort of semantic versioning for game development?

Maybe I'm overthinking but I don't have a good understanding of versioning and was curious if someone has a good write up or tutorial on it for game dev.

[potent ice]

It's more than fine to use semantic versioning for game dev. X,Y.Z were Z increments when you do bug fixes. Y increments when features are added or tweaked. X for larger changes. You can also greatly simplify it if nothing external is using your game like some api or protocol.

Some start at 0.1.0 and work towards 1.0.0 for the first playable version of the game

Then 2.x.x is iteration 2 of the game

etc etc

If you find yourself splitting the game into several projects it really gets a lot more important doing versioning right

What client, server, utility library version fits together etc

[ionic pond]

So I need help with updating my dialogue box every time the user hits the space key. Im new to python, and i cant really figure out how to display the old text withoiut i tovewriting the new text

heres my code:
https://hastebin.com/okahobavil.http

[dawn quiver]

how can i fix this

[potent ice]

You are comparing an integer and a list in there somewhere. Just print the variables or the pycharm debugger

[dawn quiver]

[cold storm]

UPBGE engine

Panda3d

never tried this but it could be nice

@mighty mason

[normal silo]

I recommend moderngl over raw pyopengl if you want to go that route.

(because if you use pyopengl directly it's very likely that you will end up making your own moderngl)

On the other hand, using opengl directly in python has a learning resource advantage, you can directly follow tutorials such as https://learnopengl.com/

(have to convert from C to Python though)

The window size is what?

Sometimes the window can shrink after opening it

You have hardcoded 1920 x 1080 resolution

query the actual window size to be sure

[vocal pagoda]

yes that's is the windows size

[potent ice]

Move the text more to the left? 🤔

[vocal pagoda]

ok

[potent ice]

There could also just be something with how you handle the text in TextUI

Often it's a good idea to isolate a single text element and see if you... for example can make it left align in the upper left or right corner

Just use your creativity to debug things

It can also often help to simplify things and build it up again slowly

make screenshot and count the actual number of pixels with some image editor

@vocal pagoda Is there a global state in pygame that can offset the rect coordinates?

[vocal pagoda]

I don't know about it

Hello,
I would like to know if with Tkiinter version 8.6.9 it's possible to embeding in a tk Frame a window pygame (2.0.2).
I saw it' was possible with

os.environ['SDL_WINDOWID'] = str(frame.winfo_id())
os.environ['SDL_VIDEODRIVER'] = 'windib'

but these are olders version and it doesn't seem to work

All code find on Internet :

root = tk.Tk()
embed = tk.Frame(root, width=500, height=500)  # creates embed frame for pygame window
embed.grid(columnspan=(600), rowspan=500)  # Adds grid
embed.pack(expand=True)  # packs window to the left
buttonwin = tk.Frame(root, width=75, height=500)
buttonwin.pack(expand=True)
os.environ['SDL_WINDOWID'] = str(embed.winfo_id())
os.environ['SDL_VIDEODRIVER'] = 'windib'
screen = pygame.display.set_mode((500, 500))
screen.fill(pygame.Color(255, 255, 255))
pygame.display.init()
pygame.display.update()

[lean lagoon]

anyone good at pygame that can tell me why dis dosen't work ´´´py game_font = pygame.font.Font(r"C:\Windows\Fonts\arial almindelig",40 )´´´

can you share it as well?

[lean lagoon]

@snow hill is just says that file not found but that is the correct file path

r"C:\Windows\Fonts\Arial\Arial Almindelig.ttf
whats the diffrents? in this paths?

[snow hill]

a truetype font usually comes with either a .ttf or .otf extension, yes

at least on Windows or Linux

my advice would be to copy the file from the Windows fonts folder to your project folder

and see if the name displayed by Windows is different (or not)

Uhm how should I handle wall collision with this type of movement : I click the screen then the player moves closer to my mouse

and add a for loop on the top then check if not colliderect() [I have 4 walls]
I currently want the player to stop upon collision.

[odd cypress]

what is the use of combinedly using pygame and tkinter?

ppplllllllllllllll

[potent ice]

Let's say you want to use tkinter features and just draw with pygame or something else to a frame

That is possible with pygame, sdl, opengl etc

It's a little bit of low level window magic

[cold storm]

yeah, we can use shared memory space and PBO to pass buffer between apps

'shared openGL context'

[potent ice]

Even better of you don't need shared. Just make a framebuffer for the frame itself

[potent ice]

as in.. you can reallocated the underlying pixels storage so you can draw to it directly

[light cargo]

YOOOOOO

[cold storm]

it's best to do it in a fragment shader

[light cargo]

good job trueman

[cold storm]

that is almost like my blender text editor

[vocal pagoda]

Thnx

[valid marsh]

what do you mean ?

[valid marsh]

can you elaborate

[cold storm]

GPU is is cheaper to run a composition of overlaying a image over a image than to upload a whole new image usually

think about how much data has to go up the pipe basically to effect how much change

if you are going to be changing the whole screen it's best to do it in the fragment shader or a 2d filter

so you send a program to the gpu to change stuff there using uniforms

and forgo shipping a whole buffer to / back each frame

[valid marsh]

ohhh

ummm

i am using pygame

pure ygame

so i dont have access to the GPU

i need to do every thing on the cpu

https://stackabuse.com/advanced-opengl-in-python-with-pygame-and-pyopengl/

@valid marsh

[valid marsh]

yeah ik that pyopengl exist but i am trynna learn how everything works

fyi i got the solution to that

in pygame there is a function

pygame.surfarray.pixels3d(surface) which return a numpy array of the surface

and i can directly just access the array for per pixel manipulation

would you guys say that you use maths a lot for game dev?

[tranquil girder]

yes, but it's mostly very basic addition, subtraction and multiplication

[cold storm]

all the time

dot(), reflect(), (p1-p2).magnitude [distance]

vector 2 =  (p1-p2).normalized()

https://www.youtube.com/watch?v=DTxC5L3O13I

it gives you super powers *

[ionic pond]

your work always looks super cool!

[cold storm]

Thanks! using py blender + learning vector math makes you get really good at this

I recommend blender geo nodes as a good basis to learn this now

also eevee shaders

[ionic pond]

hehe, may consider paying more attention to my math classes

[cold storm]

you can learn more in 2 days of concerted effort then a lifetime of school

[ionic pond]

i agree

[cold storm]

play with blender for sure

you can see the math

[ionic pond]

blender looks super cool

[cold storm]

it's 100% free

I help test/maintain the blender fork upbge

where youle restored the game engine to blender 2,8+

after it was cut out do to too much techical debt

he just ate it, and ported it to the new render engine / depsgraph

[ionic pond]

i havent seen many people use py blender

but it looks amazing

[cold storm]

addons for blender are made in py

also the game engine has a scripting layer in py

but we use bpy meshes now, so you can use the addon api in game

• modifiers like geonodes

[ionic pond]

keep up the good work btw!

[cold storm]

geonodes let you wield C++ / threaded

you can feed them attributes in py though

or move a object they are using a axis as a driver for

like a object moving up can drive a whole sim

"time"

that is how the wave video works above

see the purple value?

on the bottom left

I clicked 'copy as driver' on a objects position Z axis and pasted it there

so py can move the empty -> moves the waves

or terrain or whatever

[cold storm]

[onyx sapphire]

Hello Newbie here.
I'm looking to learn more of python through game dev and i want guidelines.
Like which game engine to use

??

[potent ice]

There are lots if libraries you can use to make games. pygame, arcade, pyglet, ursina etc etc

It really depends what you want to make

Some libraries are closer to "game engines" while others are more like graphics/media libraries

[onyx sapphire]

which are closer to game engine

[potent ice]

That doesn't mean it's the right choice. what are you planning to make?

hi

please help me i am making my first game in python

i have an issue!

[potent ice]

You might want to introduce a separate hit box for your sprite or your character sprite frames needs to be moved all the way to the bottom of the texture.

I think adding support for a separate hit box solves many other problems. Instead of relying on the width and height of your sprite you instead check the hit box (for collision). It can just be four values (x1, y2, y1, y2).

The more fancy collision systems use polygons instead making it more accurate. Tiled editor also support making polygons for that specifically.

BUT maybe start with boxes unless you are feeling very brave.

[ionic pond]

Thanks for all the feedback! I’ll see how I can improve it

[potent ice]

You can also kind of automatically calculate a hit box by looking at the pixel data. Many libraries do that. That's fairly simple with rectangular hot boxes. For more fancy collision I would recommend hand crafting them in tiled editor or possibly using pymunk to automate it.

[ionic pond]

Thanks! I’ll look into that

[potent ice]

You could possibly peak at what arcade does. It's more or less created for projects like this

[frozen knoll]

I’m not sure if I should be posting this in here or data-sci but I’m trying to figure out how to use ffmpeg. I’ve got a replay file that contains hit objects as well as mouse pos/movement and I want to convert the replay to a mp4

Do I have to do some sort of headless render and send that to ffmpeg or can I render with it directly?

[dawn quiver]

teach me master

[potent ice]

If you can create rgb pixel data you can dump raw frames to ffmpeg. A simple capture feature in moderngl-window : https://github.com/moderngl/moderngl-window/blob/master/moderngl_window/capture/ffmpeg.py

I've just crated pixel data with pillow once drawing lines visualizing vectors, then dumping that into the capture thing above.

It was certainly not perfect, but it did the job in minutes.

Shapely or cairo can also work if you want it more fancy

how to install ursinaengine

[potent ice]

https://www.ursinaengine.org/#Getting Started

[brisk pecan]

Sup fam, does anyone have any experience with WrapAround in games like asteroids, snake?

[potent ice]

More specific? You're just talking about objects disappearing and re-appearing on the other side of the screen?

If that is the case: With asteroids type of games it's common to make the object leave the screen entirely before it re-appears on the other side for simplicity.

For snake it really depends on the implementation. If it's grid based it's fairly simple to wrap around the screen.

[frosty yew]

this is really cool I will have to look into some game dev stuff

[cold storm]

was able to make a game loop using geonodes and py + upbge !

I think you can use Modulo

and if the thing goes to far on X it will pop to zero automagically

so we have its 'incident x' and its actual X

[left jetty]

Say you have a rod 5cm (or 5cm radius) pointing north how can rotate the rod so that it points east ?
,

[summer ledge]

does surface.blit allow a list parameter?

[brisk pecan]

like this one

When the object touch or go over the "screen boundaries", make it appears in the other side following the path (hypotenuse)

[brisk pecan]

I would like to keep the initial trajectory.

[cold storm]

it will I think

if you use modulo X and modulo Y

so we have - add velocity to 'base' X and y

then after to get incident x and y we do

newVector = [math.mod(old_vector[0]), math.mod(old_vector[1])]

oh nm

this would spit it out whereever it crossed on the other side I think

[brisk pecan]

Cheers @cold storm I will have a try this arvo.. I did a whole calc from that (black triangle) than I set the x,y to the base and "draw" another triangle (the one with green line) to set the new position.

But with that I would have a lot of problems with collision detection as well

gosh damn.. such a basic stuff, giving me some hours of headache.

[cold storm]

I can help I think

intesect point line

can yield where it will cross

I think you can flip the ratio

oh nm

that would be a different triangle I think

[brisk pecan]

My fear is that all code that I'm typing, could be summarized in less than 10 lines.

and then I had stress over something that I didn't need to.

Hey, i have created a game using pygame module, have images and sounds in two separate folders.
Now I want make a SINGLE package executable file so that i can distribute it among friends.
Now the problem is everytime i am using pyinstaller main.py --onefile --noconsole
This command and run the exe inside dist. It's showing fatal error, could not read script.
I tried moving the main.exe to the folder where all my assets were. But still didn't work. Showing the same error.
Anyone have any solution?

[crisp junco]

how's your folder structure?

if you could just paste it over here

is this okay?

keep the images and sounds folder in the dist folder along with the main.exe

[patent dock]

i did that but it didn't work

this is what the error

[crisp junco]

I don't have much experience with pyinstaller

sad

like to whomsoever you're sharing this exe with, just tell him to install python and run it

it'd be much easier

[patent dock]
