sure you can have all sorts of models procedurally generated

[arctic flare]

Hello, anyone know a lib that connects to a Minecraft server apart from mcpi and discordSERV?

[mystic epoch]

What software do you recommend to make a 3d game which wouldn’t need any pre made assets or prefabs

[vagrant saddle]

probably Panda3D

[mystic epoch]

Would you recommend making a 3D game on python

[vagrant saddle]

it would probably depends on the game, but Panda3D core is written in C++ anyway

[arctic flare]

Bump

[finite solar]

As @vagrant saddle said you can use Panda3D. You can also use Ursina which is based on Panda3D or Pyglet which is in pure Python and uses OpenGL. Although it might be very hard on Pyglet to make 3d games.

[mystic epoch]

Sorry it’s just I’m tasked with making a “game” doesn’t have to be 3d could be 2D but everything must be made by me, textures, the Players first person pov and what not all the code everything. so Would this change exactly what I should use or would panda 3d still work

[vagrant saddle]

you should make a ray casted game with pygame, there are plenty of examples around

[dawn quiver]

nice 😄

yes

[dawn quiver]

you could make a clone of a game. I don't see why it has to be completely originally

[finite solar]

I'm not too familiar with Panda3D but if you use it for a 2d game it will require a lot more work than using something like Pygame.

I'm not too sure on the restrictions of having to code everything. But if you use Pygame you will have to create your own game loop and game object for your game. I hope this helps

[paper sandal]

Anyone familiar with the PAWN language, which has been described as mashing Python and AWK together?

just finished the first part of my 4 part project

it’s gonna be huge

it’s all up on my github

WIP Harfang3D GUI

try this one, all done in Python:
https://github.com/harfang3d/game-astro-lander/releases/download/2.1.0-hg3.2.4/astrolander_release2.0.0_hg3.2.4.zip

you can also pull the whole repository

it runs straight from the clone

it's a little workshop I did with a team of CS students

they created each one a level of the game

(you have all the levels in the latest commit)

[dawn quiver]

Hello can i see your project?

[snow hill]

you are probably not using it properly 🙂

try the .bat files

[snow hill]

Ok 👌

Will try on my side and make a short video

It should help

Thanks for testing anyway

BUT

A screenshot with an error message would help 🙂

[dawn quiver]

Ooo nice work

[snow hill]

@dawn quiver 🙂

[snow hill]

Can you try double clicking on the .bat files ?

[plush wedge]

oh sure

[snow hill]

wip car driving simulator in python

[dawn quiver]

I wanna talk about pygame

[vagrant bobcat]

what is this?

I've never seen code like this before

[signal creek]

@vagrant bobcat sorry for the late response. It's a language I built myself. Just finished defining everything after 2 years

[vagrant bobcat]

woah

[plush wedge]

Here’s a project I’m working on, this is just the output of the code I spent days typing, there’s other output’s to the first input but i just wanted to show what would happen if you didn’t follow the instructions

[vagrant saddle]

i think most .bat or .cmd are quarantined by default if coming from internet on recent windows

[tame patio]

I am trying to make a arcanoid clone using arcade, which engine should I use. I tried arcade.PymunkPhysicsEngine but it is not working properly

[dawn quiver]

Hi

[spiral skiff]

What then snakes doin

[raw shadow]

def return_map(
        self,
    ) -> list[pygame.Rect, list]:  # sourcery skip: for-append-to-extend
        self.map_array = []
        x_rand, y_rand = random.randint(0, self.height), random.randint(0, self.width)
        print(x_rand, y_rand)
        color = WHITE
        for y in range(self.height):
            for x in range(self.width):
                if x == x_rand and y == y_rand:
                    color = RED

                x_pos = x * self.block_size[0] + 5
                y_pos = y * self.block_size[1] + 5
                self.map_array.append(
                    [
                        pygame.Rect(
                            x_pos,
                            y_pos,
                            self.block_size[0] - 10,
                            self.block_size[1] - 10,
                        ),
                        color,
                    ]
                )
        return self.map_array

one of the squares should turn red, but its not turning red. which sorta seems impossible as im generating a random int in the domain of the nested loops which the random number should match at some point

[snow hill]

as I was unable to complete my #PyWeek34 entry, I decided, at least, to make a decent readme file so that people can see how it was supposed to look like (I even included a "release")

[haughty goblet]

hello I am currently recreating mario on python thanks to pygame and I would like to know the pygame method which allows to move the window if there is one of course

[dawn quiver]

I am assuming you want to change the view

[dawn quiver]

https://www.pygame.org/docs/ref/camera.html

The math for a view or camera is really simple but you can use pygames camera object if you need to

[dawn quiver]

what does that do?

[haughty goblet]

thanks i think i found it

[snow hill]

It’s a GUI library :

https://github.com/harfang3d/harfang-gui

[snow hill]

You downloaded the zip from the release section, you clicked on the .bat file and it still fails :/ ?

Can you post a last screenshot to help me figure out what’s wrong ?

You downloaded this file, right ?

[snow hill]

ok

do you know how to run a .bat file ?

a .bat file is for Windows, no for PyCharm 🙂

you simply need to open the Windows Explorer

then, locate the folder where you unziped the game

then, double click on "2-run"

(the .bat file format was created around 1980, I assumed it was obvious you had to run it from Windows and not PyCharm, sorry 🙂 )

[spice cliff]

What would you recommend as backend/engine (in Python) for web-based 2d multiplayer action game? I decided on FastAPI with Websockets for now, but maybe there is something better I could use 🙂

[dawn quiver]

Pygame can be ported to the web now, but the answer depends on the exact game you are making
If it's just clicking in buttons and getting certain options then maybe your approach right now is better, but personally speaking if it's something like a platformer I'd use pygame and package it with pygbag

[spice cliff]

Hmm... but that would be frontend part in that case, or em I missing something? Could you elaborate a bit more about how whole stack and communication could look like?

[dawn quiver]

You can take a look at https://github.com/pygame-web/pygbag

Here's the demo page: https://pmp-p.github.io/pygame-wasm

[dry frigate]

hey guy
I'm new here
I want to create a Voice Voice Assistant on replit and we can talk back and forth together
I guy have any idea or keyword?
thanks a lot

[spice cliff]

I checked those it doesn't seem that there is any client-server communication or at least I couldn't figure out how it works

I think in this project backend is only limited to serving assets amd there are no calculations done on server side for game itself

To build multiplayer game I need client-server communication, client-client may be useful as well

For the frontend side I'm a bit concerned about using it for larger game, how does it compare to JS ones?

[dawn quiver]

https://www.youtube.com/watch?v=0ZONMNUKTfU

As seen in pikmin three's final boss the plasm wraith

[snow hill]

https://www.youtube.com/watch?v=q6VamFH_Xcs

[sweet shard]

Brython for the front end would be a good choice

[spice cliff]

It should be faster than pygbag, but still relatively slow. There are many slow operations: https://brython.info/speed_results.html

It may be work with pixi.js, so even if a bit slow it is still valid choice

[sweet shard]

Yeah it won't be the fastest but you do get access to all of the Javascript browser libraries which is nice

If speed is an issue I believe there's another python library that precomplies your python into javascript

[vagrant saddle]

it also allows websocket operations , webrtc, direct use of javascript libraries, and also compilation of python code to wasm with mypyc. it is just not documented right now.

brython is great but you cannot use compiled python libraries that require reference counting

[dawn quiver]

I am at a weird impass

[vagrant saddle]

i don't get what you mean there's no backend at all, everything run client side

[spice cliff]

Well, for game dev speed is very important. I want to avoid situation when I have to rewrite whole game after a few months of development because framework speed is low

[spice cliff]

I specified in my first question that I'm asking about backend for multiplayer game 😮

[spice cliff]

We probably shouldn't use Python libs anyway. They will be much slower than JS ones

[vagrant saddle]

tbh compiled wasm python is faster than uncompiled native python ...

[vagrant saddle]

depend on game communication model but with a messagebox like a websocketed irc channel as a cheap backend, you only need client logic and python wasm can already connect to websocketed irc without problem.

[spice cliff]

It will be still slower than pure JavaScript

[spice cliff]

What do you recommend as communication model for action/shooter multiplayer web game?

[spice cliff]

"websocketed irc channel" - what is it? Could you give me a link?

[tranquil girder]

if you're making backend, that is, running code on a server to communicate with clients over the internet, wasm and all those are irrelevant. you can just run CPython or PyPy or something like that. I assume since you're posting on the Python discord that's what you want to use. And it works well for that. There are lots of libraries in the standard library and others which work well.

[spice cliff]

Yeah, I asked about backend, so I'm a bit surprised about getting answers related to frontend only...

[tranquil girder]

Like the socket module

[spice cliff]

As I'm mentioned in first message I'm using FastAPI with websockets as web backend, but I'm not sure if this is right direction to go

I'm also thinking about adding separate engine app that will communicate with FastAPi via Redis, because FastAPI doesn't support long running tasks

[tranquil girder]

Or the one you're already using, FastAPI. I think as long as it's tried and tested, it's good. I don't really have any experience with this.

[spice cliff]

It would work like this: Frontend (websocket) <-> (websocket) FastAPI (redis) <-> (redis) Engine app

[vagrant saddle]

for action/shooter there's too much latency, use webrtc (udp based) instead

[spice cliff]

WebRTC is peer-to-peer, so it doesn't use server at all

Without server I won't be able to ensure that players aren't cheating

[vagrant saddle]

webrtc can use a server, peer to peer does not mean always serverless

eg http://www.quakejs.com/

[spice cliff]

I didn't know you can use this protocol for client-server communication, do you know any good framework that supports it, like FastAPI?

[vagrant saddle]

there are some, but in the previous link it is https://github.com/HumbleNet/HumbleNet

[spice cliff]

This one has bindings for C and C#, it doesn't seem to be Python lib

[vagrant saddle]

well C is not a problem for python

and you probably want your netcode in wasm to prevent (a bit) from cheating

[spice cliff]

You can run it - yes, but it won't be easy to develop without bindings

I noticed HumbleNet uses both WebRTC and Websockets, so perhaps I don't need WebRTC part in first place

There is also https://github.com/aiortc/aiortc that seems to be recommended only for audio/video steaming

[vagrant saddle]

usually websocket is used for peer discovery ( by adressing the server ) and then switch to webrtc

[spice cliff]

This would make much sense 😮 I guess chat part could be in websocket

[vagrant saddle]

yeah aiortc seems good for making the server

[spice cliff]

It could be, I probably would have to pair it with some web server like FastAPI anyway

Do you have any speed comparison between websockets and webrtc?

[vagrant saddle]

udp (webrtc) is 2x faster

[spice cliff]

Websockets are supported in almost any web server while webrtc needs additional setup, so I would like to ensure it's worth it

[vagrant saddle]

also routers on internet prioritize webrtc traffic

[spice cliff]

How did you calculate that?

[spice cliff]

Source?

[vagrant saddle]

udp is one way, so half the time of tcp handshake to get back

counterpart is you can lose data in flight

[spice cliff]

It is one-way because it accepts that you may lose data, but it doesn't mean it is 2x faster

TCP and UDP are similar, but TCP will wait for packet if it is lost

And this is only at network level, if we want to compare WebRTC and Websockets we have take into account that those are different protocols not only at network level, so we have to use real tests

It would be different scenario when you send multiple small events compared to sending one large file using those protocols

I would like to have this kind of performance data

[vagrant saddle]

you are both right and wrong, but for action/shooter which you asked for it's 2x faster because most event don't need ack as they are merely world updates

[spice cliff]

I doesn't sound right, I know UDP should be faster depending on how WebRTC is implemented compared to Websockets, but it shouldn't be 2x. I would like to see any tests proving it. Otherwise it is just your theory 😄

[vagrant saddle]

just consider that websocket has xor'ed chunks and is encapsulated in TLS and has no control over maximum transfer unit. A very simple test is compare unix network file system (nfs) speed on a lan with tcp and then udp

[spice cliff]

Comparing TCP vs UDP is not comparing WebRTC vs Websockets 😄

[vagrant saddle]

indeed, websocket is so much worse than tcp that nobody had to demonstrate it

[spice cliff]

It is faster than HTTP and better supported than WebRTC. People use it for games and video/audio streaming without problems

I agree that WebRTC should be faster and better for action game, but I need to know exact numbers to justify more complex implementation

[vagrant saddle]

1. get the numbers yourself if you don't trust random people that actually work on the tech 2) webrtc is not more complex

it's making reliable messaging with it which is more complex

btw about latency this one is interesting https://www.ggpo.net/

[spice cliff]

1. I will do it, but since you are so sure there is 2x increase in speed I was hoping that you actually tested it 😄
2. I'm not saying WebRTC is more complex as a protocol. I saying that my specific game implementation would be more complex if I use WebRTC since it is not as well supported as Websockets in various frameworks

[spice cliff]

It is, but is there a way to use it in web browser?

[vagrant saddle]

it is already used in web browsers eg in wasm4 fantasy console

[spice cliff]

Building GGPO is currently only available on Windows....

Windows builds requires both Visual Studio 2019 and CMake.

Are you sure?

Could you send me some more links?

[vagrant saddle]

Ok, thanks

[distant dove]

I need some major help and I don't even know where to start. I could use some good help in port forwarding, or whatever I need to do to make my code work on remote devices (it works on my own device but not connecting different devices). I know the general idea of it, but I want to be able to provide a .exe file of my code online for anybody to use, and I don't want to have users of my code to have to go through a whole process of port forwarding. How do I implement something like this into my code?

[torn jackal]

hello guys, someone knows how to make Steam Achievements in python ?

[sweet shard]

I don't know the specifics but you'll want to look into the Steamworks SDK

[torn jackal]

I will watch again, because it didnt some much helpe me

@sweet shard Actually Steam just show us how to od it in C++

[untold sentinel]

Maybe you guys can help me

My group decided to build a topdown game (with Unity) for our term project

We're all fine coders, and are not particularly worried about that aspect of things. But we've hit a wall when it comes to graphics

If we want our player to be able to, say, use a bow in addition to a sword, we need a set of sprites that can show that. If we want any kind of a story, we need NPC sprites.

And, none of us can draw

[dawn quiver]

Hire someone

[proper peak]

I'd unironically look into AI generation for that. Sadly, from my experiments, general-purpose stuff like stable diffusion is optimized for high res and performs horribly for pixel art or low-res (well, you could generate a high-res sprite and pixelate it but that has its own issues); you need a dedicated model.

[untold sentinel]

The only thing I can think of would be making a 3D low poly model, animating that, and then pixelizing it

[proper peak]

e.g. https://libreddit.tiekoetter.com/r/Cataclysm_DDA/comments/tb2rpk/pixel_art_cutting_edge_ai_generation/ which used https://github.com/pixray/pixray

[dawn quiver]

You could, but why not just use a pixel image studio?

I’m sure there is something that could help you create sprites.

[untold sentinel]

3D is marginally easier on my brain. Though I suppose we'd get better results with a pixel engine

[dawn quiver]

Oh I just saw, you need it animated?

Like a shooting animation?

[untold sentinel]

Well, our character is going to need to be able to move. That means a walking animation. In theory, we can just do two directions (left and right, one being a reflection of the other) which makes things a bit easier. But in addition to walking, we'd need a melee attack animation and an idle state. And then if we want anything beyond that, like using a bow or casting a spell, that's a different animation for each

Then there's enemies, which will all need a walking and attacking animation, and NPCs which need walking animations

[dawn quiver]

How would you import it into Unity? As a video? Gif? As a 3D model that preserves the animation? Because depending on what you use will change what you have to do.

[untold sentinel]

Unity consumes sprite sheets — each sprite in the animation, regularly spaced

It automatically creates subsurfaces from the sprite sheet, and wraps them up in some kind of SpriteSequence object. It's pretty much automated

[normal silo]

Your scope is too large. Sword or bow, pick one. At least one person should be dedicated to graphics only.

In top down you can split the sprites into parts. Head, body, legs.

Make the NPCs not animated other than simple bobbing up and down programmatically (they don't walk / move around). Then make multiple static NPCs that you can talk to by giving them 1 of 3 hair styles and changing the colors (variations).

[hushed marten]

Anyone knows about UI game dev ?

[tame patio]

What lib are you planning on using

[dawn quiver]

Hello everyone I have a question.So I wanna make a game with a friend of mine and I have a made the character already on blender and my question is that do I do the code on blender or use other app/game engine?If you recommend another app can you tell me which one should I use!

[blazing void]

Hello, I made an simple dvd screensaver (I wanted at beginning to implementing to switch the dvd logo to cat pictures with using an API and then I noticed it is pain to download pictures from url, so I gave up the idea) and and to ask if is there is something what can I optimize?
https://paste.pythondiscord.com/lafuxecayu

[native seal]

as long as you have a direct link api for the cats its a case of using open("cat.png", 'wb').write(requests.get("direct-image-link").content)

to download pictures

[blazing void]

yeah but it says something like the content don't match with type

maybe somewhen I will try to implement it again

[sweet shard]

Pythons main 3d engines are Panda3d, Ursina (which is built on top of Panda3d and simplifies somethings), and Upbge which is a fork of the blender game engine

As long as you're okay with your game code being open source It sounds like Upbge would be the best fit for you

[sweet shard]

Yeah the steamworks sdk is written in C++ I believe so unless you can find someones Python bindings for it you'll have to write your own

[torn jackal]

OK thanks man

[vagrant saddle]

like https://github.com/philippj/SteamworksPy maybe ?

[hushed marten]

maybe tkinter

[tame patio]

I know a bit of C, Could I help?

[dreamy pagoda]

im using sockets for a multiplayer locally hosted game and my client easily connects to the server when both are run on the same machine, but client throws this error when i run the client on a bridged adapter VM

what might cause this?
i don't think it's a firewall thing because i had been able to connect this way a week or 2 ago

[hushed marten]

👊🏽

[frank field]

Hey @dreamy pagoda!

It looks like you tried to attach file type(s) that we do not allow (.mkv). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

[dawn quiver]

Oh thank you for letting me know. Also sorry cuz I didn't mention that the game we will make will be probably be on C or C++ since my friend started with C and doesn't really know python so sorry about that! I will keep it in mind for when I work with python! (Also for some reason discord bugged and I din't reply)

[dawn quiver]

On the game I don't think it will be possible since most things me and my friend have thought about putting in the game are some things we won't be able to show you so I am sorry.If you mean telling me what game engine I could use then sure

im making the movement for my game rn but only for some directions the left and right work, the other direction they are both really similar to up and down
can som1 help

    def movement(self):
        sin_a = math.sin(self.angle)
        cos_a = math.cos(self.angle)
        dx, dy = 0, 0
        speed = PLAYER_SPEED * self.game.delta_time
        speed_sin = speed * sin_a
        speed_cos = speed * cos_a

        keys = pg.key.get_pressed()
        if keys[pg.K_w]:
            dx += speed_cos
            dy += speed_sin
        if keys[pg.K_s]:
            dx += -speed_cos
            dy += -speed_sin
        if keys[pg.K_a]:
            dx += speed_cos
            dy += -speed_sin
        if keys[pg.K_d]:
            dx += -speed_cos
            dy += speed_sin

        self.x += dx
        self.y += dy
``` this is most likely the thing causing the movement to be weird

bruh now after i continued the code the movement stopped working

i need to display text to the pygame window

[ancient shale]

im trying to make a guessing game but the computer guesses my number. each time the computer guesses a number, i decide whether the number is too low or too high

 import random
 
maximum = int(input("Maximum number: ")) 
minimum = int(input(" Minimum number: ")) 
answer = input("Answer: ") 

x = random. randint(minimum, maximum) 

while x != answer:
     print(x) 
     y = input("Higher or Lower: ") 
     
     if y == "H":
         minimum = minimum + 1

     elif y == "L":
          maximum = maximum - 1

but i camt seem to figure out whats the problem here

[elder needle]

Is pygame a solid development method or is it like a meme?

I'm a bit confused on its legitimacy

[dawn quiver]

Here is a small implementation of your idea:

import random


def main():
    select_random = determine_number()
    find_number(select_random)


def determine_number():
    minimum_number = int(input("Enter the minimum number: "))
    maximum_number = int(input("Enter the maximum number: "))

    select_random = random.randint(minimum_number, maximum_number)

    return select_random


def find_number(select_random):
    counts = 0

    while True:
        answer = int(input("\nEnter your estimate number: "))

        if select_random == answer:
            print(f"It took you {counts} attempts to find the right number: {select_random}")
            break

        else:
            print("Not yet. Try again!")
            counts += 1


if __name__ == '__main__':
    main()

It's one of the most popular libraries to make visuals and games. Completely legitimate.

Are you expecting some AAA game or something? 😄

There are definitely python games on steam made with various different libraries

the only other python "game" engine that is actually used for lots of "games" is Ren'Py. I put "games" into quotes, because it's an engine for visual novels. I believe "Doki Doki Literature Club!" is made using Ren'Py.

the original, yup. For the Plus release, they painstakingly ported the entire game to Unity (since that allowed releasing it on non-PC platforms too).

[eternal vessel]

People are just concerned of it because Python is a slower language, but it's fully capable, if you have $5 you could try one of his games. Their kinda hard though so beware on that

[dawn quiver]

You can try his games for free as well. https://dafluffypotato.itch.io/

[dawn quiver]

There are. This is coming from someone who has used pygame a whole lot! Made a few PRs here and there too.

It's a great tool, but you definitely won't find it easy given the amount of control you have, you have to plan everything if you want a nice end product. It's what me and many others like to do, and are good at, but if you aren't up for that I'd recommend something with a little bit more abstraction
Godot and GD script are great

Don't be discouraged from using pygame though, its definitely usable for what you're talking about, but you need to know what you're doing which may take some time to cultivate

[woven canopy]

So, odd question. Last night was on the LearnPython reddit, helped a guy with a few bugs he had in a text adventure game he was having. Now I've made a couple of these before when I was initially learning, but then shifted to more roguelike design games. And helping him out brought me to a question.

So say you're making a "map" for a text based game, each location obviously needs to link to several others. In the guy I helped's each location name was tied to a dictionary, which's keys/values were the move-commands/destination room. Which that worked.

Just been thinking though. For that game there was about 8 rooms, with about 2 adjacencies each. Obviously if one wanted to scale this up a lot, you might end up with 100 rooms each with a couple adjacencies. Any thoughts on how to efficiently generate/encode those?

[dawn quiver]

does anyone have a good beginner project I can try?

looking for ideas.

[woven canopy]

How big you want to go/experienced you are?

A great early option, try and remake "The Oregon Trail" as a text game (you can find basic templates for this all over the net. And then just add stuff to it for a few days). Then if you feel a bit more confident, maybe step otu of console and try and make it again (but better) with pygame and a 2d interface.

[teal gulch]

What are the most complex types of games python can make?

[olive geode]

python can make any type of game

[teal gulch]

Open world?

[olive geode]

any type of game

[teal gulch]

Damn, i didnt know that, i thought complex games like open world needed game engines, uk anything about open world python? Idm learning

[olive geode]

Game engines are there to help with game development. But they have no bearing on the capabilities of what one can do with python.

[teal gulch]

Ye i dont, i still think python is like a baby language, ik its useful in some careers but i want game dev so..

[olive geode]

python is used to power some billions dollars companies. It's far from what one would call a baby language

[brazen leaf]

can I get some help with an extremely specific problem in vc

[untold sentinel]

I could use some help thinking my way through some procedural generation stuff

[brazen leaf]

i tried doing to same thing. I gave up

[untold sentinel]

Its a top down game, for a school project. It doesn't need to be big or even great, so long as its been well thought out

I can see why procedurally generated and, more specifically, open worlds are not common for topdown games. World traversal in these games is made more interesting because you are directed by the shape of the level to only ever move in one direction (more or less), and you are constantly met with obstacles which must be bypassed one after another

This, and height differentials in the landscape is tricky. For the most part you can't have anything lower behind something which is higher. You can get away with something lower if what's higher is only ever higher by one level, but it starts looking very off if the differential is too great.

And then in terms of obstacles, they have to be "wide" or "long" enough to force the player to go far out of their way for them to be worth the time.

Does anyone have any experience procedurally generating a topdown world? Anyone have insight?

[dawn quiver]

When I think of top down games I think of binding of issac. It is a top down dungeon game.

It is also called a rogue like

If you dont want to go that direction maybe legend of zelda?

They are several algorithms for generatig room layouts.

http://www.roguebasin.com/index.php/Articles#Map

You could make up your own algorithm. Doesnt have to be complex. Some can do it.

The Coding Train has a maze generation video and a video on wave function collapse

[untold sentinel]

More like zelda — big open world with relatively few obstructions

I mean, not to put too fine a point on it, what I had envisioned was a topdown BotW

[dawn quiver]

Is this your final project?

[untold sentinel]

On a small scale, of course. But that's a tricky notion without being able to climb, swim, etc

Our term project — though the majority of the project emphasizes planning, requirements specifications, various design diagrams

[dawn quiver]

What can you do?

[untold sentinel]

When I say "procedural open world" I mean something ultra simple. But, it does need to be well thought out.

[dawn quiver]

Do you know how to detect collision

What about resolving the collision after

[woven canopy]

So you want to procedurally generate a GB zelda-esque map?

[untold sentinel]

Something along these lines

[dawn quiver]

ok just doing that might be enough

[untold sentinel]

As for collision detecting, Unity should take care of most of it

[dawn quiver]

maze algorithm might be good for that

but the mazes generated from that are a bit narrow

and not open enough

could be modified to be more open

https://www.youtube.com/watch?v=HyK_Q5rrcr4

Maybe use this for each room

not whats in the rooms

but for the rooms themselves as pieces to the maze

then modify the algorithm to be more open

where each room has four possible exits

[woven canopy]

Yeah, 1 "easy" way would be to maunally creat a bunch of "tiles" that your map generator can piece together to make your map. Set some of the edges to have exits, and the generator will stick more tiles on such that you can keep the maze going

[dawn quiver]

oh

[woven canopy]

If you reach a dead end, just throw trees or other obsticles at the end of that road, and flag that area to spawn something. (Maybe a fight, have a chest spawn, whatever)

As far as blocks between major areas

[dawn quiver]

id look into wave function collapse wich is really just a fancy way of saying what Nikarus just said

each room tile has four possible exists. Either there is an exist or there is not. That is 2^4 possible room tiles

so 16 room tiles

https://www.youtube.com/watch?v=rI_y2GAlQFM

[untold sentinel]

So, this game won't actually have any dungeons

[woven canopy]

Might want a couple extra tiles to account for possible vertical movement. EG second stories of houses, or going down in dungeons

[woven canopy]

Yo that's an amazing video

[untold sentinel]

We don't have time to implement a dungeon generation algorithm AND a world generation algorithm. I had though of maybe implementing "natural dungeons" which tightly clustered world objects like trees, cliffs, etc, to make for a puzzle of sorts

But even that is a stretch. What I do want is for the world to feel organic (easy enough with noise), for the world to be open, and for the world to have at least some interesting aspects to it. Consider spawning a forest. Its simple enough to plop clusters of trees down on a flat grassland

[dawn quiver]

This could be an algorithm for you world

[untold sentinel]

But there's nothing to that

[dawn quiver]

it doesnt have to be used for dungeons

[woven canopy]

This is fine, you can make some regions favor more open tiles (for the more overworldy feel), and others favor the more mazelike 2 entrance tiles in windy patterns

[untold sentinel]

Windy as in winding?

[woven canopy]

Yes, sorry

[untold sentinel]

As opposed to blowy, gusty 😛

So, lemme clear the air on something. The key to making world traversal interesting is to provide some kind of resistance to traversal. Most levels do this by having you move on a set path, and placing obstacles in front of you one by one, right? BotW does this by letting you climb and swim and all sorts of fascinating movement mechanics

[woven canopy]

Mind oyu the Wave Form collapse/maze is what you do as a first pass to make the overal terrain. You can have a script run over it after, and say you've got a large wide open area... plonk down some buildings to make a village, or a nice 24x24 area might be flagged as an area for a boss battle

[untold sentinel]

So something I should be keeping my eye on is having enough freedom of movement to make the world feel open, but "reigning in" the player's motion enough to make getting around a challenge

Does this make sense?

[woven canopy]

Well if you go mazelike then the maze itself is resistance. Another goto is enemies. For "natural" obsticals, you can always resort to pits the player needs to jump over, rivers with current they've got to get across (and if they don't make it, get swept downstream to where they started)

Zelda games typically blocked off areas by requiring an item that you get in a dungeon to clear or bypass obsticles. Rocs feather to jump pits. Power glove to pick up and move rocks. The speed boots would let you charge through some obsticles, or when combined with the feather would get you across long pits.

Sometimes you had to shoot targets to trigger bridges, the hookshot was a thing or the "swaphook" from Oracle of Ages

[untold sentinel]

Note: these sorts of obstacles rely on "walls" of sorts — like big spans of trees which are impassable, with a hole between them

[woven canopy]

Yes and?

[untold sentinel]

This. Interaction-activated obstacles. Good call

Well, with an open world, you aren't really enclosing the player in impassable borders and limiting them to points-of-access

*Avenues-of-egress

[woven canopy]

The whole world doesn't need to be completely open. There's plenty of places you get stuck going a single path in Skyrim or Botw

Also, when we talk before about generating a maze. The maze doesn't need to be 1 tile wide. You can have "open feeling" areas, where you're still in a maze, but the paths are 16 tiles wide

[untold sentinel]

So, what I think I'm picking up on

Is points-of-egress

So, I've got a big ol' world. Say, 2000x2000 tiles. This world is broken into regions each 200x200 tiles wide. Maybe one region is a desert, another is a forest, maybe a river-delta/lakes area

[woven canopy]

Can I post a link to a map from a game here, is that allowed this disc?

[untold sentinel]

I don't see why not

[woven canopy]

https://mikesrpgcenter.com/zelda3/maps.html

this is the map for A link to the past

[untold sentinel]

Thank you! Its hard to find large scale topdown maps

[woven canopy]

https://mikesrpgcenter.com/zelda3/maps/lightworld-6-5.html

this is the starting house. Now, remember what we were saying about the 16 tiles (each tile can have 4 exit points, so theres 2^4 possible tiles to build the terrain out of)

Consider that your terrain map tiles, can take any size from 3x3, up to like a 16x16

a 16x16 can have 4 exits, just like a 3x3, the 3x3 is just more total wall than walking area

This "Link's house" area, is made up of a bunch of different ones of these

Like the main path across the bottom from right to left, that's a bunhc of maybe 5x5 tiles with east/west exits. There's 1 with a north exit that leads up the ramp to the house on the left

[untold sentinel]

Respectfully, I'm a bit less worried about algorithm at this point

[woven canopy]

What one might do, start off with a 3x3 "overall map", this is where you set your regions. Regions define what kind of enemies might spawn, "Density" (walkable area vs wall), the color palate. Perhaps each region has a single major objective (the "dungeon" if you will). Can merge a couple of these major regions to make a superregion if you want.

All of these regions have at least 1 connection to neighboring regions.

Break each Region up into areas, these are where your maze generator code goes to work. Set 1-2 connection points on the edges where you'll need to link up to other Regions. Plop your objectives around in random spots, generate paths between them, and throw in some noise to fill each place with side paths. Things don't need to fit together perfectly mind you. You can ahve areas that are inacessible that are jsut a swathe of trees or mountain.

[untold sentinel]

I don't think this is the direction I want to go. But I thank you for taking the time

🙂

I want the world to be the opposite of a maze

[woven canopy]

Then use wider paths. Fact is, at the end of the day, every game world in a top down game is to some extent... a maze

they just don't look it because they're zoomed way in

[woven canopy]

I do really recommend the video linked before about waveform collapse. I understand you don't want mazelike (thats more my word for it tbh, as I started learning this stuff from maze generation)

But if you will, consider this timestamp. https://youtu.be/rI_y2GAlQFM?t=564
On the grid he's generated out of these tiles, the top left has a cluster of 6 tiles that are all interlinked.

The whitespace inbwtween those doesn't need to exist in the final game, it jsut exists when generating the... topology perhaps, of the map. That NW corner could be made to be 1 wide open space

[velvet tendon]

hello

[woven canopy]

That whole 4x4 he's got could be a fairly open area, with a big ledge stickign throguh the western side, and a lake on the right or such

[woven canopy]

Hello

[woven canopy]

Do you have a question perhaps?

[velvet tendon]

no not really just wanted to say hello to anyone here :]

[woven canopy]

Aah, that's fine too

[last moon]

Not exactly sure what I’m asking but how do you go about doing (for clarity’s sake) harmonics?
Kinda had an idea for a physics sim where when objects collide they produce a ring/wave that grows out until it hits another object/limitation.
First thought was to create 360*x objects in a linked list and interpolate between them but I don’t think that’ll work properly

hi. So, I have to implement conway's game of life for a school project. In my code, I have a list of list. Every "tick", I replace it with a new list, using the following function:

def update_grid(grid):
g2=grid[:]
for y in range(grid_resolution):
for x in range(grid_resolution):

        number_of_neighbours=0
        for x1 in range(0,3,1):
            for y1 in range(0,3,1):
                if (x>=-x1+1 and x+x1-1<grid_resolution) and (y>=-y1+1 and y+y1-1<grid_resolution) and (not(x1==1 and y1==1)):
                    if grid[y+y1-1][x+x1-1]:
                        number_of_neighbours+= 1
        g2[y][x]=False
        if number_of_neighbours==3 and grid[y][x]==False:
            g2[y][x]=True
        if (number_of_neighbours==3 or number_of_neighbours==2) and grid[y][x]==True:
            g2[y][x]=True

return grid

This doesn't give me the expected results, and I don't know why

Help pls?

[woven canopy]

What results are you getting? As that might help narrow down the issue.

additionally, if you put 3 backticks (usually to the left of 1 on your keyboard, same button as ~) before and after a comment, itll render it more like code

def update_grid(grid):
    g2=grid[:]
    for y in range(grid_resolution):
        for x in range(grid_resolution):

            number_of_neighbours=0
            for x1 in range(0,3,1):
                for y1 in range(0,3,1):
                    if (x>=-x1+1 and x+x1-1<grid_resolution) and (y>=-y1+1 and y+y1-1<grid_resolution) and (not(x1==1 and y1==1)):
                        if grid[y+y1-1][x+x1-1]:
                            number_of_neighbours+= 1
            g2[y][x]=False
            if number_of_neighbours==3 and grid[y][x]==False:
                g2[y][x]=True
            if (number_of_neighbours==3 or number_of_neighbours==2) and grid[y][x]==True:
                g2[y][x]=True

    return grid

Is just a tiny bit more presentable

[misty quarry]

As far as I could tell, the problem seems to be that I'm not getting the correct number of neighbours (I'm getting less)
also, thanks for the showing text as code tip, I didn't know how to do that

[woven canopy]

Just remembered you can also do this. Using quotes in place of the backtics. '''py ~code ''' and it'll color it

So a question on your code then, getting yo line 11, you have too few neighbors you say

            for x1 in range(0,3,1):
                for y1 in range(0,3,1):
                    if (x>=-x1+1 and x+x1-1<grid_resolution) and (y>=-y1+1 and y+y1-1<grid_resolution) and (not(x1==1 and y1==1)):
                        if grid[y+y1-1][x+x1-1]:
                            number_of_neighbours+= 1

I assume this is the bit that's supposed to look at the 8 adjacent cells.
Walk me through how that If is supposed to work, like what are each of the pieces supposed to do?

I ask this as, it looks like you're trying to detect the edges of your grid, to avoid checking for cells in those locations.
If X,Y is 0,0 meaning say the top left corner. What's with the -x1+1?

[misty quarry]

It's the same as x+x1-1>=0, I just made it more confusing (also when I was testing it, the iteration went from -1 to 1, but I thought that was creating an error, so I replaced it)

That's what the +/-1 is there for

Well this bit looks like its good then, but you're getting too few number_of_neighbours. Are you able to manually set up a test grid and step it once to see the outcome?

(Also is grid_resolution supposed to be the size, liek 20 nets you a 20x20 grid?)

[upbeat plinth]

Hey Guys, check out this cool workshop on Android Development! I've been meaning to learn android development, could someone please tell me if this is worth attending?

the link is www.techfest.org/workshops/appdev

[woven canopy]

Huh, if I manually creat a grid (4x4), and change line 13, g2[y][x] to = number_of_neighbors (and comment out the rest), and run it, I'm getting 6 neighbors on cells with 3 and 4neighbors

even just a 3x3 grid with a 1 in the center outputs this after 1 iteration

[3, 4, 3]
[2, 4, 3]```

Seems each iteration that you finish counting neighbors, and then update a cell in g2. You're also editing that cell in grid (or g1 if you will). So for a 3x3 grid with a 1 in the center. top left gets checked first, it has 1 neighbor so it puts a 1 in there. Cell to its right gets checked, it should only have 1 (the cell below it) but because the original array has been updated, the top left has a 1, so now we actually have 2 neighbors

Doesnt explain the 2 in the bottom left though

[misty quarry]

I think I got it to work

It was because of the changes being made to both grids, so I just made sure to create a new grid for g2

(I am not very familiar with python passing by value or reference thing, because I usually use c++, which makes it easier to know how things are changing behind the scenes)

thanks

Are there any gamedev here who are making games for the Raspberry Pi ? 👍

[last moon]

Actually any literature on the math behind physics in video games would be great

Modern or not

[dreamy pagoda]

is it common practice in multiplayer games to have other players have a separate class with different movement physics to attempt to "predict" movement in order to mitigate the effect of latency?

[tranquil girder]

yeah, basically the one the user is controlling is "real", while all the others are "fake". they're just visuals trying to match the other players as good as they can, but they usually interpolate the movement for example, so it appears smooth

[sweet shard]

I've been messing around with gamedev on the Pi that but haven't made anything substantial

[snow hill]

ok 🙂
could you tell why ? workflow problem ? not enough GPU / CPU power ?

[sweet shard]

Workflow can be an issue for me. Just because the pi lacks a lot content creation tools. Personally I never hit any GPU/CPU issues

[dreamy pagoda]

and how often is their real position updated really? i'm making one myself and currently it seems to be able to update about 12-13 times per second, and because i'm not simulating any movement yet, even though the game is running at 60 fps, because the other players are only changing their position when an update is received, it appears as if they're displayed at 12-13 fps

i was under the impression before this that, because it's a pixel art game and the data i'm sending is very small, it would be able to update frequently enough that, without simulating movement, they would update 30-60 times per second

[last moon]

I’m guessing a majority of that latency depends on how quickly you can send inputs to the server and how quickly the server can send updates back. If you’re not using some sort of p2p and solely relying on a dedicated server, latency will be noticeably higher (don’t quote me on any of this I’m very sleep deprived)

Poke mentioned interpolating between those updates and that’s probably why they appear choppy/laggy (could be a number of causes but if they’re just teleporting around this might help)

[dreamy pagoda]

i believe it's not that, i added some time.perf_counter() prints right before and right after the commands for listening and most of the latency seems to be here https://cdn.discordapp.com/attachments/878686998829879356/1031981454802034789/unknown.png

each message is taking about 40ms

[last moon]

What’re you pickling

And how’s your server being set up? 13ms seems strange to me

[last moon]

Mind sharing the code? Probably a bit easier then asking a slew of questions 😄

[dreamy pagoda]

its not the first print i just picked one little bit from the hundreds

[waxen hawk]

was there any btc giveaway recently?

someone dm me that i won 0,.42 btc

[dreamy pagoda]

i mean it's pretty long but basically

[waxen hawk]

i came in third place

and i dont see any giveaway channels

[dreamy pagoda]

https://paste.pythondiscord.com/wasuhulenu this is the server function, https://paste.pythondiscord.com/ewilenebag this is the threaded function i run on the client, and here are the methods it calls https://paste.pythondiscord.com/xeviduhosa

[waxen hawk]

someone please answer me

[bitter compass]

why would there be a crypto giveaway from this python discord?

[waxen hawk]

its possible tho

well now ik

[bitter compass]

btw this is in the wrong channel, there's a few off topic ones / general you can ask instead

[waxen hawk]

ty hes probably a scamer

ok tnx

[last moon]

Do you use any sort of multithreading?

[dreamy pagoda]

yeah

both on the sevrer and client

that function from the second link

[last moon]

Where is it being used?

[dreamy pagoda]

on the server, whenever a client connects it runs a threaded while True method

and on the client, whenever the game loads an area it starts a threaded function aswell

also while true, until leaving the area

the server method just listens and replies with something depending on what the message was

the client one only sends update requests

[last moon]

If you get a chance to look into github that’d help a bit, part of the problem is probably (?) how you set up the threads - from what I can tell send/request are running successively which would slow down data flow

Network wise I have 0 clue what I’m doing and don’t really feel like being malicious atm 😄

[dreamy pagoda]

when i say request i just mean the client sends the server the player's data

the server interprets that as an update request

and sends back the data for the players in his area

there's just a send line of code followed by a receive line of code

[snow hill]

okay, thanks...
we're evaluating if it's relevant to build HARFANG for the Raspi...
https://github.com/harfang3d/harfang3d
it would be in 64bits (and that's another issue, potentially)

[faint bane]

why won't my sprite be able to move right

[dreamy pagoda]

@last moon i managed to get it working

apparently these are tcp packets, and tcp by default waits a certain amount of time to send, in case the sender might want to send more data, so it can package the data and send a single package in order not to clutter the network

by using this socket setup, instead of sock_stream, you can force it to send asap

I think this is the correct place? As an administrator I'm trying to install plotly to the Python plugin for UE5, C:\Program Files\Epic Games\UE_5.0\Engine\Binaries\ThirdParty\Python3\Win64>python.exe -m pip uninstall plotly, however it keeps saying the access is denied. I know that you can install to that file due to reading https://filipsivak.medium.com/python-in-unreal-engine-the-undocumented-parts-7585434f5d76 where the person ran C:\Program Files\Epic Games\UE_4.27\Engine\Binaries\ThirdParty\Python3\Win64\python.exe -m pip install numpy and it worked for them. The folder itself isn't read-only but rather the files inside it are. Another odd thing is that I somehow managed to install numpy and matplotlib, checked the dates the folders for them were created, even when it kept saying access was denied. I also just moved the files I made on that day to a separate folder and tried to see if I can install matplotlib and numpy again, it doesn't work and says access is denied, and I checked in the Win64 folder, nothing appeared. So far I've checked controlled folder access is off and the folder is not encrypted. In fact it's greyed out.

I'm really not sure what to do now. Please ping on reply and thanks to anyone who does.

What makes for a good open world in a 2D game?

Here are my thoughts

We're building a topdown with an open world for our CSCI265 term project. I've got a handle on the basics — simplex/perlin noise layered ontop of each other, and multiple passes over the world to add increasingly fine-grained detail

But then I picture in my mind creating a forest. Is it just a flat expanse of grass tiles with trees thrown in? That's not fun or impressive. Speaking from what little I know about good level design, I know that part of a good game experience is making world traversal interesting.

Often this means putting obstacles in front of the player that they have to bypass using items or by climbing/etc.

But with an open world, free movement in all directions means that a player can just go around most things. "Wide" obstacles like rivers or elevation changes can sorta solve this, but if you rely too heavily on this then your open world just becomes a series of massive "rooms" connected by the very same maze-like/graph-like points of egress that an open world is designed to avoid

Any thoughts?

[proven shore]

hi, I like games like this, even with the obstacles, after cleared the character will be able to move around with this,

you can also make enemies too powerful or maybe with a necessary item or move to kill

[proven shore]

with this, you can make it with many kinds of tiles, it will can be generated in a random and interesting way,

also, depending on how your game will work, you can make an encounter when some area is generated, depending on status, weather, time, something

And a bunch of trees blocking the vision of the game in the background is cool!

[frank field]

Hey @brisk skiff!

It looks like you tried to attach file type(s) that we do not allow (.mkv). We currently allow the following file types: .gif, .jpg, .jpeg, .mov, .mp4, .mpg, .png, .mp3, .wav, .ogg, .webm, .webp, .flac, .m4a, .csv, .json.

Feel free to ask in #community-meta if you think this is a mistake.

[dreamy pagoda]

i found this online

so it wouldn't work

at least the way my networking is currently coded

[boreal seal]

thats pokemen not man theres 2 people

Is outthere any sugsesful games made in python?

[uncut bolt]

I wanna make a game, but i cant code 💀 r there any game types where u draw and design a lot but little coding? Cuz im blank on that part haha

[vagrant saddle]

"story telling" and "point and click" game types

[uncut bolt]

Ehm, do u have any examples? Haha

[vagrant saddle]

https://www.renpy.org/ and lot of games from sierra/lucas art

[tawdry sluice]

hi guys

[vagrant saddle]

like "day of the tentacle"

[tawdry sluice]

so I have been working on a pygame for about 2 months(I am slow)

[uncut bolt]

Ahhh like ddlc

Tysm! :)

[tawdry sluice]

And I just realized its a multiplayer game

and I dont know anything about networking,

any good advice here?

[vagrant saddle]

question is a bit too broad, networking requirements vary from game to another

[tawdry sluice]

so It's a cards game

and I need to send some cards id mostly

[vagrant saddle]

then i'd suggest an irc channel and some json

[tawdry sluice]

I saw some socket tutorial, is it good?

[vagrant saddle]

no need to go too low level, any client irc lib will do

[tawdry sluice]

oh I see, so socket is too basic?

oh no

I am dumb

the opposite

?

[vagrant saddle]

yeah the socket server part can be complicated

[tawdry sluice]

I see

[vagrant saddle]

an irc channel will handle the annoying stuff for you

[tawdry sluice]

thanks man I will look for that

so hmmm...

I don't get what exactly is icr

[vagrant saddle]

irc is a simple protocol layout upon a tcp socket server

[tawdry sluice]

somehow sockets looks easier to me XD , thank you man I will look more into it

[rare oracle]

I'll develop infinite button presser ( pro game development moment )

sorry to ask this here, but I don't never did a full project, and I want this xp, so anyone here wants help to develop a game or want to join me in creating a game?

[woven canopy]

I mean I have my own silly projects, but what are you interested in making?

[proven shore]

actually, my silly projects, too!!!

lol

I never developed anything like a full big and functional project

but I want to learn and make something!

I have a lot of little games that kind of work, but none really ready

also, i can join some project

[smoky berry]

what is the best game programming package?

(serious game, free package, startee one)

[ancient jetty]

Its not much, but its all i can make

And im kinda proud of it

How can i improve It?

1: better buttons
2: a background
3: sounds
4: a timer for when the text goes away (or another screen for the text)

Pls add to list if you know anything

[untold sentinel]

I'd like to pick everyone's mind about world design best practice for a top down rpg

I'm building a topdown with an open world for my term project this year. It's for software design class, so design and forethought is more important than the actual implementation. In the very least, I need to be able to say I made sensible choices

So, what makes for a good "world" in a top down game?

[nimble dagger]

i'm using pygame as an audio analysis gui and a nonblocking pyaudio stream to collect real-time microphone data, but frames get skipped sometimes. does anyone know how to ensure that no audio frames get dropped?

[proven shore]

hi

[proven shore]

how are you collecting the packages of sound

what the size of the stream?

[nimble dagger]

12000

with a global variable in the callback function

i use np.frombuffer and multiply the chunk by two numbers

[proven shore]

I miss a way to show the NPC play

[proven shore]

did you try decrease this value?

[nimble dagger]

no, but i will good idea

[proven shore]

try it

i had some problem like this

and some times, the package is not lost, but pygame just don't play it

sometimes you have to increase the channels it uses

don't know why, but ...

[nimble dagger]

you mean stereo might make pyaudio drop fewer audio frames?

i am collecting mono at the moment

[proven shore]

no. I don't know what you are doing, but if you are playing the sound collected back, sometimes it just don't play

if a lot of sounds are played at the same time, this happens

[nimble dagger]

no, i'm not playing it back. just analyzing it and displaying the results on the screen

[proven shore]

so maybe this will help

[nimble dagger]

perhaps. i will try it. thanks for your help

[potent ice]

If you are CPU bound you could do some work in a separate process?

Just communicate with a Queue to make it simple

[ancient jetty]

Ah, good point!

[faint bane]

i have questio

while True:
clock.tick(60)
for event in pygame.event.get():
#controls + easter egg
if event.type == pygame.KEYDOWN:
if event.key == pygame.K_LEFT and sprite_x > 0:
sprite_x -= x_velocity
pygame.time.delay(5)
pygame.display.update()
elif event.key == pygame.K_RIGHT and sprite_x < x:
sprite_x += x_velocity
pygame.time.delay(5)
pygame.display.update()
elif event.key == pygame.K_UP and sprite_y > 0 :
sprite_y -= y_velocity
pygame.time.delay(5)
pygame.display.update()
elif event.key == pygame.K_DOWN and sprite_y < 800:
sprite_y += y_velocity
pygame.time.delay(5)
pygame.display.update()
if event.type == pygame.MOUSEBUTTONDOWN and no_clicks == 0:
screen_colour = purple
if event.type == pygame.QUIT:
pygame.quit()
quit()

DISPLAY.fill(screen_colour)
DISPLAY.blit(text,text_rect)
pygame.draw.rect(DISPLAY, black, (sprite_x, sprite_y, 80, 80))    

  
    
pygame.display.update()

why does the screen collision not work properly

it'll stop but it'll do so too early or too late

btw here are the sprite coords: sprite_y = y/2-40
sprite_x = x/2-40
x_velocity = 80
y_velocity = 80

[untold sentinel]

I want to run something by you all, just to check my understanding of the situation. I'm building a procedurally generated open world for a topdown as part of my term project. Unfortunately, its been proving difficult to find prec-gen tutorials any more detailed than just creating height maps.

Anyway, some theory: key to a good game experience is making world traversal interesting, and, to impose challenges upon the player as they approach their goals. The standard approach (the only approach prior to advent of open world generation technology) has been to create linear levels which channel the player in one direction — forward. Since there is only one way forward, the player will be forced to overcome (as opposed to simply go around) any obstacles placed along this path. Multiple paths can criss-cross, or else branch into multiple directions. Various graph based procedural generation techniques can be used to generate such a map.

Open worlds throw a wrench in this. If the goal is unencumbered movement in all directions with smooth transitions from region to region/biome to biome, then its much more difficult (though not impossible) to place obstacles between the player and the goal. The player can just go around.

Some options for address this are: encase the "core" or "goal" of each region in radial obstacles like mountain ranges, systems of rivers, and so on; provide a main path to the core of each region and make the off-path areas more difficult to traverse; turn the world into many many many crisscrossing paths with many obstacles on each.

Does anyone have any experience or insight they can share?

In terms of procedural generation, I'm having a bit of a mental block. Naively, I originally thought that multiple passes by noise algorithms and then direct construction-of-features algorithms could create a natural feeling landscape. This approach works for landscapes which look natural, but it doesn't necessarily make for a good play experience. To do that, I somehow need to treat individual landscape components (mountains/ranges, rivers, patches of trees) the way an artist treats paint. Then, I'd need to use some algorithm to generate a landscape designed for playability from these components. I'd need to do this while somehow keeping things feeling natural

[proper peak]

Depending on what kind of game it is, the "radial obstacle" in question can just be increased mob levels/some other kind of difficulty, the closer the player is to the goal.

Avorion comes to mind, which actually does both - the game has a natural goal of reaching the center of the galaxy, and the game makes this hard both by increasing the difficulty of, well, everything as you get closer to the center, and also the central region is encased by an impenetrable Barrier that you need to do a multipart quest to cross.

[untold sentinel]

So, everything I've said thus far makes sense, right?

[proper peak]

Seems about right, sure.

[untold sentinel]

So here's my problem. I need to make a procedurally generated world with tight constraints. The world needs to have two mountain ranges — one volcanic for the fire dungeon, and one snowy for the ice dungeon. I need a dense forested area, a desert, a swamp, and a lakes/river-delta region. And, I need to generate these regions such that the world still feels organic. Ontop of this, I need to facilitate borderless world traversal in all directions while still presenting the player with obstacles.

Making the first constraint work with the second, I can't just divide the world into clumps, each clump being a region. This will make it, well, clumpy. There would be no satisfying mountain-range-wrapping-around-plains effect, and other such organic sorts of geography. It'd just be clumps. Somehow, I need to apply realistic generation such that every region is present, of a decent size, and largely singular (patches of biome-x scattered around, independent of the main biome-x-region are fine)

[tranquil girder]

This sounds like cutting edge stuff. I've never played a procedurally generated game with good level design at least. Is there any reason you can't make the levels by hand?

[untold sentinel]

Yeah, its a tall order. Maybe its too difficult 😐

[untold sentinel]

I feel like its waveform collapse (or some such) to the rescue

Maybe

Here's an algorithm with some ideas I'm trying to absorbe

http://www-cs-students.stanford.edu/~amitp/game-programming/polygon-map-generation/

What about spilling the island into Voronoi cells, and then, placing two mountains and a big ol' lake. As happens with the algorithm I posted, altitude would then decrease from mountain ranges by distance, until the ocean is encountered. Next, built rivers coming off from the mountains. Knowing now where the moisture is and what the elevation is, I could classify cells into biome types and it would already be mostly perfect.

Deserts would be low elevation, low moisture. Swamps would be low elevation, high moisture. Forests would be mid elevation, high moisture. Grasslands would be mid elevation, low moisture.

The issue is ensuring that each of these four regions is present, in an acceptable quantity, and that its a singular region as opposed to cells scattered everywhere

[normal silo]

Same as my previous answer to the art assets question. Your scope is too large. No open world (as in large open areas, having many rooms/screens to go between is different), no procedural generation. Your goal should be to make something like the original Zelda and even that will not be as easy as it seems.

After completing it, if you need something to show off your programming skills (although being able to make any complete game shows enough practical skill IMO), you can always add some fancy shaders / lighting / vfx or enemy AI.

[untold sentinel]

Thank you, for telling me what my goal should be. Lord knows, I'm incapable of deciding that for myself.

[dry cloak]

Not a very important question but its a problem ive encountered and i might learn a thing or two from it.

So i have this basic pygame script which stores every frame

import pygame
pygame.init()

screen = pygame.display.set_mode((500, 500))
clock = pygame.time.Clock()

frames = []
player = pygame.Rect(0, 0, 50, 50)

while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT: pygame.quit()
    player.center = pygame.mouse.get_pos()
    screen.fill((255, 255, 255))
    pygame.draw.rect(screen, (0, 0, 0), player)
    pygame.display.update()
    frames.append(screen.copy())
    clock.tick(60)

(Apologies for any syntax errors, i typed it on mobile lol)

The problem with it is that it seems to take up alot of memory very quickly. running this at 60fps averages around 1-2 minutes = 1gb of memory 💀 (well according to task manager, on my hardware atleast.)

How could i reduce the impact of this?

[normal silo]

Are you trying to record the screen the entire running time of the game?

[dry cloak]

Pretty much

I cant really give a particular circumstance since im not actually using this in a game, just playing around and tried to make a game recorder

[normal silo]

Video recorders get complicated because of this. They need to compress and also save to disk.

[dry cloak]

Probably beyond me then

As of my current knowledge atleast

[normal silo]

You could probably get a library to do some of it for you.

Maybe convert the surface to an image and have Pillow compress it for you.

[dry cloak]

Pillow can compress images?

Ive only ever used it to get a list of rgb tuples from an image file

[normal silo]

You can also only save the past N amount of time, and have it overwrite the older stuff.

[dry cloak]

Or say only record one in every 2 frames
So basically lower the framerate of the recording

[normal silo]

If you save to PNG or JPEG format it is compressed.

PNG is lossless, JPEG is lossy but more compression.

[dry cloak]

Which one can compress/save faster?

Or would it not matter because they are both so fast

[normal silo]

That too, but I meant that you have a buffer of size N and you store that many frames, and when it goes past that limit it wraps around to the beginning, replacing the older frames.

So it contains the past N frames.

There are also video libraries.

[dry cloak]

Or maybe it saves those frames to a file and clears the list to make space

Then use some dark magic to fuse the files together at the end

[normal silo]

Depends what you want.

[proper peak]

Most importantly, videos are not just a sequence of images. Video codecs save a ton of space by, very roughly speaking, storing only the parts that differ from last frame.

So this approach won't get you good results even if you use something like PNG/JPEG. You really should use a video encoding.

[normal silo]

It's better than raw, PNG/JPEG, but not a full proper video.

Pretty simple to do though.

[proper peak]

I have this example of recording video from frames via ffmpeg-python: https://github.com/RundownRhino/Cellular-Automata-Simulator/blob/public/src/gameoflife_ndimage/video.py

[dry cloak]

For my simple brain thinking of it as just saving a bunch of pngs works well

What would be a good python video library

[normal silo]

ffmpeg, can't escape it.

[normal silo]

JPEG.

But it depends on if you are ok with losing some information or not.

[dry cloak]

I see that everywhere.

Only time ive ever needed to use it was a discord bot that plays audio

[proper peak]

ffmpeg-python is actually a very good wrapper IMO. like, easier to use than the CLI.

[dry cloak]

Btw tysm for the example

Ill definitley go through it and try to learn something from it

[normal silo]

Using ffmpeg CLI is something else. An experience.

Like we never left the 90s.

[proper peak]

I have a markdown document with command line commands I saved for later use and like half of it is ffmpeg 🥴

[dry cloak]

https://tenor.com/view/bye-chat-goodbye-bye-burmese-python-python-gif-23678463

[proper peak]

ffmpeg -i ".\filename.mp4" -map 0 -dn -ignore_unknown -c copy -f mp4 -bsf:a aac_adtstoasc result.mp4

ah yes, totally comprehensible

[normal silo]

It's like how we used to edit text with ed. Before vi/vim.

Line by line in the CLI.

[proper peak]

tbh the reason I'm eager to say that example is because it took me a Journey to learn how to do this

I spent a looong time doing stuff like saving frames as pngs to disk, making gifs out of them postfactum, etc

and then, eventually, like a ray of light in the darkness, found ffmpeg's -i pipe: (or however exactly it's spelled) option, which powers the example i posted

[normal silo]

I used to learn this stuff, but stopped. It's not my job to configure things due to arbitrary complexity that should not exist (e.g. Linux config files for random things I don't care about).

(Devops is NOT for me)

(Because of Python / it's many libs I can avoid much of this now)

(ffmpeg is also kind of an extreme case)

Hi guys I’m currently making a text based adventure game using Python. For some reason when it asks “would you like to see you’re stats” for some reason it when it prints the vars they are all zeros. Can someone please help.

Hey guys, I am trying to learn PyGame Library and also work with it, I decided to do a proejct of "falling food objects" in a supermarket where a cart should "catch" those objects and get score and level up. When level goes up, the velocity of the objects go. Now, I have a small bug with it, I try to do the system that it will spawn a random object from the food classes objects I chose. Now it does work, and the Y of the object goes up (The object goes down) so the physics works, but, I try to make a condition that when the object's x value is in the range of the cart's x value and the object y's value is the cart y's value the object disappears and a new object appears but I have no idea of how to do that system. And else if the object touches the bottom of the map without the cart picking it up, then do something else (I will add 3 hearts and each time 1 heart will go down). Now somehow I have some problems with these specific conditions. All the other things work pretty good. If someone can take a look and tell me what is wrong and how to fix these conditions in the code I'd really appreciate it

https://github.com/idoredid123/PyGame-Project

The code is in the main.py file

If you can DM me with what is wrong I'd be super thankful C:

[faint bane]

how do you get screen collision to work

i can't find the exact value

the sprite collision will work

but it'll go too far or too little

[wicked hinge]

Are you talking about mobiles and their shots? did you manage to compile the game

[faint bane]

no

just so sprites dont leave the screen

[faint bane]

wdym compile the game

you want the code?

[faint bane]

fyi python isnt compiled

[dawn quiver]

then that's called "transpiled"

well, it doesn't really matter

it compiles to bytecode, let's just say

[faint bane]

sorry lol

alr

can someone help with my screen collision thing

just tryna keep the sprite from leaving the screen

but i can't get it to stop at the screen

edge, it always stops too early or too late

wait lemme try smth

maybe

how do i position the sprite in the center of the screen

first

ok

so like

if the screen is 800x800

and sprite width is 80

itd be

360?

it looks a bit left

right*

fully 80 pixels

its just a black rectangle for now

i just used this: pygame.draw.rect(DISPLAY, black, (sprite_x, sprite_y, 80, 80))

im new to game dev stuff lol

idk

it might not be right

might just be my brain

idk

alr

nah i think its good

so now

the screen collision thingy

the sprite moves 80 pixels right when the right arrow pressed etc.

so i made the sprite stop when sprite_x - 80 > 0

and sprite_x - 80< 800

ok

can you explain why?

just so i can fix these sorts of problems in the future

for moving right?

isn't it already zero

oh ye

sprite_x + 80

ohh

so just

sprite_x > 0

then half the sprite leaves the sreen

here's the main game stuff

#does moving stuff
sprite_y = 360
sprite_x = 360
x_velocity = 80
y_velocity = 80

#change colours stuff
no_clicks = 0

#game loop
while True:

for event in pygame.event.get():
  #controls + easter egg, note: fix screen collisions
  if event.type == pygame.KEYDOWN:
    if event.key == pygame.K_LEFT and sprite_x > 0:
      sprite_x -= x_velocity
      pygame.time.delay(5)
      pygame.display.update()
    elif event.key == pygame.K_RIGHT and sprite_x - 80 < 720:
      sprite_x += x_velocity
      pygame.time.delay(5)
      pygame.display.update()
    elif event.key == pygame.K_UP and sprite_y > 0 :
      sprite_y -= y_velocity
      pygame.time.delay(5)
      pygame.display.update()
    elif event.key == pygame.K_DOWN and sprite_y < 800:
      sprite_y += y_velocity
      pygame.time.delay(5)
      pygame.display.update()
  if event.type == pygame.MOUSEBUTTONDOWN and no_clicks == 0:
      screen_colour = purple
  if event.type == pygame.QUIT:
        pygame.quit()
        quit()
        

    
DISPLAY.fill(screen_colour)
DISPLAY.blit(text,text_rect)
pygame.draw.rect(DISPLAY, black, (sprite_x, sprite_y, 80, 80))    

  
clock.tick(60)    
pygame.display.update()

width and height are both 800

fyi

ok

what does max do?

oh ye

lol

https://tenor.com/view/impossible-no-way-gif-24786844

wait

why wasn't it working b4 tho

ahhhh ok

so it had to be like

uhhh

40.4

wait no

ok

isn't that just arithmetic tho

oh ye

alr ty

so basically

the velocitty stops when it gets bigger than da other number?

is that what max() is doing?

kdina

what about for right edge?

ok

wat

when i press da right arrow key the sprite jumps immediately jumps

to 720

ohhh

ahh ok

ty

thanks

I’m trying to make a spinning circle, but even tho I googled a lot I couldn’t find anything on how to this? Someone here can help?

[faint bane]

spinning as what?

movng in a circular motion

or rotating

360 deg

[fallen arch]

the circle should turn around itself in 360 deg

like spinning on the same spot

[last moon]

What library are you using? I’d say use a rotation matrix but there’s a good chance the library already implemented a way to do it

[fallen arch]

hey guys, im trying to let the player input a name, and if that name has more than 8 characters in it, keep re-running the code, however python just keeps re-running the code no matter what and i was wondering how to fix this.

import random
import time

def playerName(name):
    nameList = [" Evenbloom", " Ravenoak", " Holyfist", " Hellspark", " Truemaw", " Sagesky", " Twobash", " Swiftrock", " Mossdancer", " Bronzeforge"]

    while True:
        if len(name) > 8:
            print(input("Your name must be 8 characters or less: "))
            continue

        elif len(name) <= 8:
            print(name)
            print("The Fates were cruel when they spun your thread... " + name + random.choice(nameList) + "...\nBorn to serve the sentence of your father after his death." + "\nyou must now fight your way through the arena to be free from the chains of imprisonment...")
            time.sleep(2)
            print("You enter the arena to the roar of thousands of spectators... \nYour opponent approaches...")
            break

playerName(input('Enter your name: '))

this is what I came up with so far

ok i somewhat got it to work, except for the first if statement, where now, if you input the wrong number of characters, it just repeats over and over instead of moving onto the second portion

hi, I have some problems with numpy, will be very thankful for help

here is script

import numpy as np
import random
def func(m, a):
    x = random.randint(0, (a[0]))
    y = random.randint(0, (a[1]))
    if m[x, y] != 9:
        return x, y
    else:
        func(m, a)
a = list(map(int, input("put x and y: ").split()))
m = np.zeros((a[0], a[1]))
for i in range(int(input("bomb number: "))):
    d = func(m, a)
    m[d[0], d[1]] = 9
print(m)```

the idea is to create a matrix with numpy using x and y in "a"

then put number of bombs and randomly put them in the matrix

but it also has to be checked if the place isn't with a bomb already

what I do in the function "func"

there is a problem in the func, sometimes it generates x and y that doesn't exist in the matrix so the output looks like this: IndexError: index 10 is out of bounds for axis 0 with size 10

idk how to fix it

[torpid prism]

ok I fixed it

Guys i am really lost in something here, my big question is how the big gaming companies uses python to develop AI in their games, if most of the games are developed using C#, i need to understand where they are using python?

[sweet shard]

I don't know about all the game companies but I believe that Unity has a C# library that relies on PyTorch. If you look up Unity Machine Learning Agents you could see some examples of what they use it for

[dense trench]

First time i see that i know that unity using machine learning for their agents but never did any research about it, thanks dude i will look up for sure

[sweet shard]

No problem I would also check out Embark Studios they're doing some stuff with animation and machine learning

[sweet shard]

Looks awesome! Is it completely custom made or built on top of another library?

[snow hill]

It’s built on top of Harfang

Hey! I'm currently using a Python game engine called Pyxel. I have part of a basic platformer, but how would I go about implementing collision detection to find if a player collides with a certain kind of tile? I have a level designed in the tilemap, but tilemap(0).pget doesn't seem to work... I don't have a list of walls or anything, it's all in the tilemap. Here's the Github link: https://github.com/hedgenull/pyxel_game

clock.tick(20) makes the loop to run 20 times per second/keypress..am I right?

[faint bane]

is it a python game dev lib?

[snow hill]

Yes 👍

Python : ✅
Gamedev : ✅ (it has scene, objects, animations, physics, audio, gamepad, VR)

[faint bane]

that's really impressive

[snow hill]

this one runs in Python as well, based on the same library : https://www.youtube.com/watch?v=tpzKMSOpD8w

[tight ocean]

Just make a variable named time_a,
And set it value increasable as the time goes when pressing Q , within that time_a variable ,if someone presses enter than you can call function Quit.

Hey!
I'd like to play constant noise soundfile while specific keys are pressed. When my plane is moving (with WASD keys), this "engine sound" should be audible.
I'm using pygame.mixer to play a simple WAV file. Everything works fine but the sound is not smooth at all. Probably because it restarts with the 60 FPS ticker (while i keep holding the key down).
Any ideas how i get continuous sounding noise while a key is pressed? 🤔

[trail plaza]

anyone here good with python by any chance, have a python exercise that i have been struggling with for the past couple hours

tried posting it in the help channels multiple times but didnt turn out great

[tight ocean]

Make a bool al and bl=false,
When pressing key set al to true,

And set a condition that if al==true and bl==false then play the sound and set the value of bl=true,...
If al== false then stop sound and set value of bl=false.

[waxen dagger]

how do i make this in pygame?

just api

[edgy basin]

Ok, thanks!! Guess that works as long as i don't hold down a key longer as the length of the Soundfile.
Maybe i need to add a condition to let start sound gain, if the the mixer.channel output isn't buy anymore.

[snow hill]

hours of work, usually 🙂

• read the docs
• find a sample project on github
• try to run it
• if it run, try to modify the code, until it makes something meaningfull
• repeat until you are confident enough to start something from scratch
• define some reasonable milestones, go step by step

(probably thousands hours of work)

If you want to do a simple 2d game python works well.

[sharp tulip]

What about 3d?

[robust hearth]

It works, but I don't know if it works well. But if I'd make a 3d game I would use Ursina engine.

[alpine shoal]

What is the best practice of creating maps? In some tutorials i looked, they seem to store the maps in a list[str]. Is there a better way to do it?

[drowsy skiff]

Should

[copper thorn]

Could anyone name some cool survival game mechanics I can add to my game? It already has a lot of mechanics but I think it is still unfinished.

[dawn quiver]

I would just store the map as a list of tile indices. Those indices index into a sprite atlas or sprite array

[tranquil girder]

list of list of int is good if you need to check neighbors
while that's a good way to store maps, it's not the best way to make them
the best way to make them would be a tile map editor, either an external program or an in-game custom made one, or you can draw bitmap in something like photoshop or paint and parse it into the format you want

for smaller games, or when you're making a tutorial and want to avoid separate assets, using a string can be a good idea, it's not bad, just a hassle to edit

[last moon]

Wow that’s so cool, how are you tracking the movement?

[rain vigil]

got an issue when i try to find input on a seperate object it only occasionly owrks

[brittle saddle]

Not sure if this is the right place for this question, but lets say I would like to create a bot for the game. I don't want to use computer vision but i want to use actual game data. So for example have player position in x,y coordinates, resource to be mined at x,y. Ability cooldown in seconds. Do I need to read memory or is there another way?

[edgy plank]

Depends on a game client, really. Minecraft, for example allows for modding - so you could put it there. Some games are written in python, where injection or memory reading is a bit harder. Finally, there are games written in CPP, where memory reading is one of the options.

[brittle saddle]

Do I need CPP for reading memory or does python have that option too? Also I need to find pointers with cheat engine right?

[edgy plank]

I did it in CPP once

Not sure if python has a wrapper

[proper peak]

python has pymemory (IIRC the name). in general, reading memory requires calling platform-specific functions, win32api for windows. So if pymemory didn't exist, you'd use pywin32.

[brittle saddle]

Alright, thanks guys

[proper peak]

there's this nice series of videos (not in python, and not finished yet) on injection/memory reading/stuff like that, which I personally found very interesting
https://www.youtube.com/watch?v=m902hm3fK7Q
https://www.youtube.com/watch?v=xN5WjaeeklA
https://www.youtube.com/watch?v=Yr9qy9reLCc
https://www.youtube.com/watch?v=aLeMCUXFJwY
it's more of a "how does this work at all" than "how to do it", though.

i want it to be text based in the sense that

theres a ui with a few buttons

then theres text boxes that appear on screen with the info

Hi everyone, this is my first game dev project. Decided on making a fast 2D platformer to test my skills. Try my game and let me know what I can improve on 🙂

This is really cool jood job

Id personally like to look at the code for this project

[gleaming scaffold]

Thanks 🙂 I'd make the repo for the src public, but I might want to release a full version of the game eventually so I need to keep it private for now.

[eternal vessel]

It's pretty cool

This level's timer is broken though

Also when you're in fullscreen and try to press ESC to pause, it takes you out of fullscreen, so you gotta press it twice real quick

Aye I beat it

Getting the key on the last level was so annoying

[gleaming scaffold]

Fixed it 😄

[gleaming scaffold]

This might have to do with the way itch.io uses fullscreen. Not sure. Will have to look into that.

[eternal vessel]

Yeah, I was thinking that was the problem

[eternal vessel]

Noice

[gleaming scaffold]

Also congrats, Thanks for playing through it. I appreciate it 🙂 Hope it was fun

[eternal vessel]

Yep, I love playin' little games. Just started with itch.io

In simple cases you can start a timer. In your draw loop and decide behavior based on elapsed time?

[neon tinsel]

Hey all, where would you store multiple class objects?

Like where would you put all the lines that create those objects

[alpine shoal]

Create instances when needed

[dawn quiver]

I randomly decided to throw myself into trying to figure out python and making a basic game, how do i find a topic?

[fallow glade]

What kinds of objects?

[neon tinsel]

Like if I had an Item class

Where should I store all of the lines like

basic_sword = Item("Basic Sword", damage=100)
sharpened_sword = Item("Sharpened Sword", damage=200)

Cause if I have a ton of items, I wouldn't want to have multiple lines of that beneath the class, would I?

[fallow glade]

class GameData:
    swords: list[Item] = field(default_factory=list)
    shields... ```

[neon tinsel]

This is a data class?

[fallow glade]

Yeah

[neon tinsel]

Wait I'm confused

Is this similar to doing

basic_sword = Item("Basic Sword", damage=100)
sharpened_sword = Item("Sharpened Sword", damage=200)
[basic_sword, sharpened_sword]

[woven canopy]

no not quite

[fallow glade]

You can put all created items in a dataclass instance (or even a dict)

And access it anywhere

[neon tinsel]

but where do you put the lines that create the Items?

[fallow glade]

For eg if you want to spawn some random weapons in a treasure chest

[neon tinsel]

these lines

[fallow glade]

For spawning, it depends on what your game entails

Is it a single level, or multiple levels?

[dawn quiver]

Using pygame, how exactly would i get a rectangle drawn on the screen?

[woven canopy]

rise, I think you're jumping a bit ahead of what the average person makign their first inventory system needs, with a dataclass. 100% that hasn't been covered in any tutorial they've read

[fallow glade]

If the latter, better to have this data stored in a json or csv file
level1.json
And have a function to read the file and create a Level object

[neon tinsel]

I know a tiny bit about dataclasses, and what he suggested seems useful, but I think you're missing the point of my question

[woven canopy]
