woah

[fathom jackal]

Does anyone have recommendations for intros to node based pathfinding in a 2D space? Specifically utilizing known good X,Y coordinates as valid paths

For context: I have a 2D Space of 0,0 to 100,100 and have a list of known good locations within that space, (1,1) (1,2) (2,.2) (2,3) (2,4) 2,5) (3,5) (3,6) (4,6) as well as (1,2) (1,3) (1,4), (1,5) (2,5) (2,6) (3,6) (4,6) - I'd like to try to path find to (4,6) from (0,0) but I'm not really sure where to start.

[proper peak]

"Known good" being what?

And what cells are connected - a cell to 4 neighbours, or 8?

[potent ice]

Good old A* sufficient? https://en.wikipedia.org/wiki/A*_search_algorithm

[fathom jackal]

A cell connected to 8 neighbors. Known good should maybe be referred to as preferred paths? , I would like to use these as the locations that are available to travel, rather than the entire open space.

I could start with A* and work from there if I need more performance; I've just never tried to implement this before and wasn't sure where to start 🙂

[proper peak]

Oh, so just pathfinding on a limited set of nodes rather than on a grid. Yeah, use any graph pathfinding algorithm like A*

start with dijkstra, it's a limited version of A*

(it's equivalent to A* with a constant h-function)

[fathom jackal]

Thank you, I'll start there and see what I can come up with. Appreciate it!

[proper peak]

here's them compared

left is A*, right is dijkstra

the difference is that A* "knows" what direction it should generally be searching in, and so explores less nodes while still being guaranteed optimal

On the other hand, you can also see on this pic why many games use a non optimal algorithm instead - because even A* explores a ton of nodes it could have not explored if it was fine with a "close enough to optimal" solution

[fathom jackal]

Yeah, I can see that - I think with my limited dataset, A* should be fine. I just need to figure out the actual implementation for my purposes and the best way to store and load the navigation grid

[cold storm]

You can change the weights of a graph in realtime

For a* check redblob games

They have code even you can use in py

[proper peak]

for Python, the common way to store graphs is as, say, a dictionary mapping a node's index to a list of all nodes it's connected to.

[cold storm]

https://www.redblobgames.com/pathfinding/a-star/implementation.py

[proper peak]

e.g a 1-2-3 undirected graph would be

graph = {
    1: [2],
    2: [1,3],
    3: [2]
}

[cold storm]

It's secret

I found it it's not listed anywhere

:3

[fathom jackal]

Thanks, I'm trying to wrap my brain around this. It seems like, on bigger projects, mapping each node to tell the system how it connects would be slow and a very manual process

Surely you don't map out each option in a 100,100 grid by hand

[cold storm]

I do it with py

And I use object faces in blender

Upbge has a sprite node for eevee

Also check this out

You can have a pathfinding graph that is each "tile" and it's connection to other tiles

Then when you pathfind them you use it to build a graph from "stubs" of just those tiles

And pathfind it

It's a bit like a octree

[fathom jackal]

oooh, yeah, that's what I was thinking of when I was thinking of pathfinding

[cold storm]

Basically when you add the dictionary together for the tiles

You strip out any links to tiles not in the set

I ended up storing nodes as

(tile_index, face)

To make it easier

Then we use a table to convert to ints

Like

Table[(tile, face)]

Will spit out the node* index

And it's position in space

[fathom jackal]

Awesome, thank you

[mental jetty]

Anybody who uses pygame

You all have any idea why the transparent background of my image after I converted it and set the color key is still black?

[lament gyro]

Hello i want to make a popup with input you cant click away from does anyone know how to do that?

[rose folio]

module 'arcade' has no attribute 'AnimatedTimeSprite'

when i run my code i get this

how to fix

imports are

import arcade
import random

[fathom jackal]

https://api.arcade.academy/en/latest/api/sprites.html#arcade-animatedtimebasedsprite

arcade.AnimatedTimeBasedSprite - looks like a typo on your part?

[inner wigeon]

Maybe because your background screen colour is black?

[mental jetty]

nah it was green

but i fixed it thx

[cloud parcel]

In games like warcraft 3, certain parts of a units texture would change color based on the assigned value (not the whole texture, just a part of it)
How was this accomplished, did the textures have a specific "blank" value that would be replaced with the set value ?

[cold storm]

drivers mixing stuff @cloud parcel

like you can use a mask + object color in upbge

and show the object color only where the mask is painted

you can accomplish this in games by passing uniforms per object

[bold wadi]

I’m having trouble with some code for a Mario-inspired video game

Where do I go?

[cold storm]

like a single float 0-1 can make a rainbow of colors

[astral dagger]

In pygame my rect is bigger than the img. I used same scale for both. Any suggestions how to make img size same as rectangle size?

[covert zinc]

So I what files do you need for a game

Like main.py

And assets folder

What else

[lament gyro]

I am trying to create a game using pygame but for some reason the screen doesnt show the image/sprite i want it to render this is my code:

import pygame, sys

clock = pygame.time.Clock()

from pygame.locals import *
pygame.init()

pygame.display.set_caption('Platformer_Toturial')

WINDOW_SIZE = (400, 400)

screen = pygame.display.set_mode(WINDOW_SIZE,0,32)
Crosshair_Position = [50, 50]
Crosshair = pygame.image.load('player.png')

while True:

  screen.blit(Crosshair,Crosshair_Position) 

  for event in pygame.event.get():
    if event.type == QUIT:
      pygame.quit()
      sys.exit()

  pygame.display.update
  clock.tick(60)

[wheat ivy]

which framework should i start with ?

[steel prism]

how to make my player jump and disable the running animation

[fathom inlet]

hi

can sw gib me ideas for the #teamseas

polymars game jam

an ez one btw

[tough kayak]

u can create a game for seas

like picking up the waste products from the seas not a complex one just a simple one after picking the waste u can add a reward system

u can make it using pygame

[fathom inlet]

ok

i will make mark robber robot eating up trash and it is like snake game

[lament gyro]

Does someone know why this is not working?

[tranquil girder]

I think update should be update()

So it actually gets called

pygame.display.update()

[fathom inlet]

hey

how can

i hide st

[lament gyro]

oh yeah how didnt i see that

[fathom inlet]

like hide some object in pygame

[potent ice]

Usually by not drawing it

[fathom inlet]

hơ

how

[potent ice]

You need to some state deciding when it should be drawn or not

If you share a little more info it's easier to help

[fathom inlet]

ok

[potent ice]

The focus should be on the first problem. How you decide if something should be drawn or not, and for what reason.

[dawn quiver]

Does any1 use blender?

I'm wondering how to make something first person vire

Viee

View

I wanna make a 3d platformer with a jumping first person character

[dawn quiver]

@tranquil girder has a semi-simple 3D engine that can be used to make that kind of game.
https://github.com/pokepetter/ursina

And no, I do not know much about Blender scripting, but there are definitely many people here that know how to do that.

i dunno man i just wanna use blender i have no idea how any other 3d graphics or game engines or any of that stuff

I'm not rly good with any 3d things either

[dawn quiver]

probably pygame

there is also pyglet, ren'py, cocos2d, panda3d (for 3d), and some others

pygame be good

Or u could be like me and make console (meaning cmd prompt) based games

yes

i mean those r cool

but i wanna try 3d graphics

theres a pretty cool cheap game on pc i seen people play it b4 where u r a king and u make decisions and ur 4 bars go up or down and some decisions lead to others

like that?

oh i remember the game name

reigns

[potent ice]

Why don't you install ursina and play around with some of the examples?

[dawn quiver]

https://youtu.be/jCaDLlz_yOI

whats ursina

[potent ice]

#game-development message

[dawn quiver]

thanks

how hard is it

how do i get it once i clicked on the link never used github

[potent ice]

pip install ursina

https://www.ursinaengine.org/#Getting Started covered here and in docs

[dawn quiver]

^^

thanks

im linux user btw

chromebook

oof

I have experience with chromebooks

[potent ice]

hmm not sure if that runs on chromebook. You can always try to install it

[dawn quiver]

Chromebook works as linux

It also runs off of linux

[potent ice]

Yeah, but depends on hardware.

[dawn quiver]

Theres a linux virtual machine that is meant for developers

I've never tried ursina on chromebook tho

do i just slap pip install ursina into the shell

i use idle python

[dawn quiver]

Try to eventually get a windows or a non-chromeOs linux computer. It will make the development process much easier and faster.
I would 4 gb raspberry pi if u want to continue on linux, or u can buy a better laptop, or build a PC

[dawn quiver]

I think on chromebook u have to use virtual environments

to use pip

does ur pip work without?

theres a linux vm

ik

what do i do now

try running:
pip install ursina

It will probably say that u don't have pip

just says invalid syntax in the shell

[dawn quiver]

I mean run it in terminal

oh terminal

pip command not found

ye

so

virtual environments

venv

u need a venv

please explain im a noob at linux

I don't remember how to do venvs

pip install https://github.com/pokepetter/ursina/archive/master.zip

is the command right

no

But that gave me another idea

u could just download from github. and put that in ur linux directory

and unzip it using like:
unzip master.zip

then u could import from the master folder

[tranquil girder]

you should do python3 -m pip install ursina

[dawn quiver]

I'm on mobile so Im very lazy with typing

oh the creator is here

wassup

do what he said

wait what linux directory

with pip cmds it doesn't matter

says theres no modual called pip

[tranquil girder]

you should install it first then

https://www.tecmint.com/install-pip-in-linux/

[dawn quiver]

thanks

actually on chromebook u would do pip3

i forgot that

progress 5% im just downloading it

does ursina work for large multiple people projects or just small projects

i dont intend to make very large projects but itd be nice to know

technically multiple people could make any type of code together

the first step is a 2d among us platformer

how can..

nvm

i ment 3d

[rigid canopy]

lol

[dawn quiver]

aight running the ursina install command that poke told me to use

[tranquil girder]

Yes, it doesn't get slower with project size lie Unity does for example, since you can only the file you want. Of course if you import everything else in the game it will slow down.
I terms of multiple people, it's the same as every other code projects. But since everything's in code files, it's easier to merge than a scene file for instance

[dawn quiver]

like a +

[wheat ivy]

can we do 2d in panda 3d

?

😕

[dawn quiver]

running setup.py bdist.wheel for numpy

I want to play with Ursina again sometime... Also Mr. Petter, your Life is Currency game is confusing

stuck on this

is this supposed to happen as in being stuck on this line

[tranquil girder]

Well, it was for a 48 hour game jam :P

[dawn quiver]

yeah.

But ur art is rly cool

[tranquil girder]

Thanks ^^

[dawn quiver]

bruh its stuck on this one line

is this normal

[tranquil girder]

stuck where?

[dawn quiver]

on a line in the linux terminal nothing is happening

[tranquil girder]

yeah, but what does it say?

[dawn quiver]

running setup.py bdist_wheel for numpy . . . || -

Ursina is very large since it is based off of Disney's massive 3d engine: Panda3d

that explains more

[tranquil girder]

might be compiling or something
You don't actually need numpy though

[dawn quiver]

its probably useful

whatever it takes to make amongus themed games and send them to my friends

: )

installing be de ez part...

im aware

i understand python 3 pretty well but my only graphics experience is tkinter which is some 2003 shit

I gtg, busy with school

cya

[misty estuary]

hello

I have a question

[dawn quiver]

aight ive done that and its installed now what @tranquil girder

do i read the thing

[misty estuary]

class App:
    def __init__(self):
        pyxel.init(128, 128, caption='SeaJam Python', fps='60', scale=8)
        pyxel.load('assets/resources.pyxres')
        pyxel.run(self.update, self.draw)
        self.move_speed = 5

def draw(self):
  print(self.move_speed)

AttributeError: 'App' object has no attribute 'move_speed'

why does it do this

[tranquil girder]

You go here: https://www.ursinaengine.org/documentation.html and read the Introduction tutorial, Entity Basics, Coordinate System, Collision, and maybe look at some if the example projects

[dawn quiver]

thanks but im having issues even doing the first bit lmao once of downloaded it

`from ursina import *

app = Ursina()

player = Entity(model='cube', color=color.orange, scale_y=2)

def update():
player.x += held_keys['d'] * .1
player.x -= held_keys['a'] * .1

app.run()`

is in the code and it should be all right but aparently the modual doesnt exist

[tranquil girder]

if you're on linux, use python3

[dawn quiver]

im using python 3 right now

[tranquil girder]

it just means the python you tried to run is not the same you installed the ursina module to

[dawn quiver]

thats weird

im using 3.7.3

what am i supposed to do bout this error then

[tranquil girder]

ok, but which python did pip install to?

[dawn quiver]

python3 -m pip install ursina

is what i typed

[tranquil girder]

I think you can add the version number too, if you want to be specific
like python3.7.3 -m pip install ursina
and

python3.7.3 main.py```

[dawn quiver]

will try

command not found

thats strange

maybe a space

[lunar venture]

You probably have something like App.move_speed

You need to create an instance

[tranquil girder]

and I think you have to add --user to the pip install command or something on linux, or use sudo before

[dawn quiver]

not found

i cba

il try -- user before the command sudo didnt work

actually aids linux downlaod

never works

[tranquil girder]

what does pip3 list say? also, pip --version and python3 --version

[dawn quiver]

asn1crypto 0.24.0 chardet 3.0.4 cryptography 2.6.1 entrypoints 0.3 keyring 17.1.1 keyrings.alt 3.1.1 numpy 1.21.4 panda3d 1.10.10 panda3d-gltf 0.13 panda3d-simplepbr 0.9 pip 18.1 pycrypto 2.6.1 PyGObject 3.30.4 pyperclip 1.8.2 python-apt 1.8.4.3 python-debian 0.1.35 pyxdg 0.25 screeninfo 0.7 SecretStorage 2.3.1 setuptools 40.8.0 six 1.12.0 wheel 0.32.3

is the resut of pip3 list

[tranquil girder]

doesn't look like you installed it

[dawn quiver]

i typed in what u told me

should i type it again or somethin

if i cant download this in the next hour im moving to blender again

[lunar venture]

Maybe use a flag.

[misty estuary]

ah imma try it when i get back thanks

[balmy sluice]

I want to make the code stop running when I lose or win, what is just the code to make it stop again?

[dawn quiver]

Command "/usr/bin/python3 -u -c "import setuptools, tokenize;file='/tmp/pip-install-asazpcis/pillow/setup.py';f=getattr(tokenize, 'open', open)(file);code=f.read().replace('\r\n', '\n');f.close();exec(compile(code, file, 'exec'))" install --record /tmp/pip-record-sy48hm9e/install-record.txt --single-version-externally-managed --compile --user --prefix=" failed with error code 1 in /tmp/pip-install-asazpcis/pillow/

is the error i get when i try download ursina

i dont know why this happens but it prevents me from accessing the modual in python

[tranquil girder]

looks like installing pillow fails and the installation never finished

[tranquil girder]

maybe try with: sudo python3 -m pip install --upgrade Pillow

[dawn quiver]

ok

its the same error as last time

@tranquil girder is this a normal error for 3.7.3 python or chromebook linux

has to be something strange

ngl

[tranquil girder]

no, it's not normal

[steel prism]

any thoughts on pymunk?

[dawn quiver]

have u seen any other person in my circumstances have this error

pillow is just dead

[tranquil girder]

nope, it's probably because of the chromebook or the OS

[dawn quiver]

so how am i supposed to fix it

i dunno why it shouldnt work on chromebook its still linux

[tranquil girder]

welcome to linux hell

it's a really common module though, surely someone's had the same issue

if all else fails, you could always build from source

[dawn quiver]

i dont understand how to do that im not well versed in linux hell

i came from idle python games and gimmicks like translators in windows

[tranquil girder]

you could try installing ursina this way:

and skip pillow

since you only need it if you want to edit textures anyway

git clone https://github.com/pokepetter/ursina.git --depth 1
python3 setup.py develop

[dawn quiver]

il type that in

well it worked i think

loning into 'ursina'... remote: Enumerating objects: 302, done. remote: Counting objects: 100% (302/302), done. remote: Compressing objects: 100% (267/267), done. remote: Total 302 (delta 38), reused 132 (delta 27), pack-reused 0 Receiving objects: 100% (302/302), 7.36 MiB | 2.21 MiB/s, done. Resolving deltas: 100% (38/38), done.

was the result

so is it working?

so now i slap `from ursina import *

app = Ursina()

player = Entity(model='cube', color=color.orange, scale_y=2)

def update():
player.x += held_keys['d'] * .1
player.x -= held_keys['a'] * .1

app.run()` into the code and run it?

[tranquil girder]

yes

[dawn quiver]

will do

Traceback (most recent call last):
File "/home/octane22/python/ursina_game.py", line 1, in <module>
from ursina import *
ModuleNotFoundError: No module named 'ursina'

theres no way man

this is some strange stuff

i typed it in correctly

[tranquil girder]

you should check if pip3 --version and python3 --version are the same

[dawn quiver]

how do i do that

[tranquil girder]

you paste those commands into the terminal

for example, I get

pip --version
pip 20.2.4 from c:\python39\lib\site-packages\pip (python 3.9)

python --version
Python 3.9.2

[dawn quiver]

octane22@penguin:~$ python3 --version
Python 3.7.3
octane22@penguin:~$ pip3 --version
pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)

is my result

[tranquil girder]

try which python

or ```whereis python3.7

on linux systems there's often a python used by the operating system, and a python for the user

also, try python3 -m pip list too
to see if it's the same as pip3 list

[violet grove]

Cool

[gentle pagoda]

I also want to make game...can we use python for that??

[proper peak]

That's why we have a #game-development channel on this server, yes.

[violet grove]

wait

can

WOW

[wraith oriole]

Hi ! Can you know good version of street of rage or metal slug in python? I dont want full game just first stage

[fathom inlet]

btuh

[dawn quiver]

mmmm yummy

Cool!

Did u make it with blender python or blender python ursinq

Ursina

[dawn quiver]

I made a 2 day stick man game requiring collision

I compared coords and added a small 1 pixel pushback

Which can prevent glitches in more advanced 3d games

[dawn quiver]

Nice

[dawn quiver]

Do you share your code in github etc?

nah

its relatively easy and used in alot of borders in games imo

[dusky holly]

hi so i tried to make a platformer but when i jump the colision with the platform is disabled

[dawn quiver]

how r you doing the collision

like with coords bumping eachother?

[dusky holly]

i use pygame

here my code

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

[potent ice]

@dusky holly You might want to add some spacing to that code. When it's this compact it can be much harder to read. Not a 100% must. Just a general suggestion.

[dusky holly]

what is spacing?

[potent ice]

add some newlines separating parts of the code where it makes sense

[dusky holly]

oooh ok

[potent ice]

For example : https://paste.pythondiscord.com/uwekalaqej.properties

That's a small start

[dusky holly]

https://paste.pythondiscord.com/belexekaze.properties

like this?

[potent ice]

yeah that's much better

[dusky holly]

ooh nice

so can u help me with my problem

[potent ice]

Maybe also group the variables you declare on the top into smaller blocks

[dusky holly]

ok

https://paste.pythondiscord.com/ehasigabah.properties

[potent ice]

Small things like that make your life so much easier. When you look back at your code in a couple of weeks/months it's much easier to understand. Also easier for others to look at quickly

[dusky holly]

i see

thx for the advice

about my problem do u have any advice @potent ice

[dawn quiver]

if player.colliderect(platform):
if abs(player.bottom - platform.top) < colision_tolerance :
isgrounded = True
player.bottom = platform.top
if abs(player.top - platform.bottom) < colision_tolerance :
isgrounded = True
player.top = platform.bottom

is the bit we focus on

i personally used tkinter for my first platform projecr

it had 4 points on the rectangle labled as "collision corner" 1, 2, 3, 4 respectively

just compared coords with other object corners

[dusky holly]

ok

so i should use the collidepoint?

[dawn quiver]

yeah

imom

imo

its a good way

[dusky holly]

ok thx for the advice

[dawn quiver]

@dusky holly want me to write a kind of sample code 4 you later?

i got time dw

[dusky holly]

Yes pls

Because this solution didn't work

I don't know if its a solution but i have decreased the jumpforce and now

The characters does'nt go throw thé platform

[dawn quiver]

aight give me 15min

def drawbounce(self): self.canvas.move(self.id, self.x, self.y) pos = self.canvas.coords(self.id) if pos[1] <= 0: self.y = 1 if pos[3] >= self.canvas_height: self.y = -1

this is a bit of a code i used for a tennis kind of game

i use tkinter (canvas is basicly size of ur window and self.id is the object which ive made beforehand and its corners (inside the tkinter object making thingy)

so like im comparing pos[3] which is the final position of the object i made before hand

and u basicly do that with an object coords instead of the canvas height

the self.canvas_height is a veriable for window height and i dont want the ball to go out the screen

i could have named pos[] something else like characterpos[] and make another position set for another object like a platform called platformpos[]

@dusky holly theres prolly more ways to do it but this is the way i did it and its probably overly complex as i dunno how pygame works and it probably has something better then this

[dawn quiver]

im having a problem with ursina models

`from ursina import *

application.development_mode = False
window.fullscreen = True
window.borderless = False

app = Ursina()

maze = Entity(model = 'mazeBeta', color = color.rgb(200,100,133), texture = 'brick', position=(0,0,0), rotation = (0,0,0), scale = (2,2,2))

EditorCamera()
app.run()` is my code

mazebeta is a maze structure which i made a stored to the correct place for use in ursina

its made with blender

for some reason it wont work, it stays on a small black loading screen but when i put a file name which 100% doesnt exist it opens a full grey screen with nothing on it

i doubled checked that i saved it correctly and the code looks correct so i dont know what it is

[tranquil girder]

what does the terminal say?

[cold storm]

using py to set data from the evaluated mesh back to the original mesh - using geonodes as a game engine 😄

Screenshot of the new engine im working on

[untold sentinel]

You're building an engine? Hows it work?

[lean cosmos]

Well what part are you asking about

[untold sentinel]

Are you writing the drawing/rendering algorithms from scratch?

Or is it a UI around another engine? In either case, super cool!

[lean cosmos]

Well I’m using pygame for the ui and rendering

And thanks it’s a fun project

[untold sentinel]

I'm working on a graphics engine myself

Basically a remote-controller for a webbrowser which controls the DOM using a pythonic clone of it

can someone help me how to slow down the spaawning time like this

[twin hawk]

Hi guys

Are there any Lua developers here?

[dawn quiver]

heyy someone at #help-pear please

[gentle pagoda]

I wanna make game like PUBG

[dawn quiver]

everytime i try to import the pygame module it gives me a circular import error 😔

[distant mirage]

A circular import is exactly what it sounds like
You probably are importing a module which also imports from the file you are working on

[dawn quiver]

ah okay thanks :D

[fervent herald]

Pygame
Is this rotate code is correct, u der roatate function, if yes then there is a problem that my image got ripped off when rotated more and more in loop

I am learning pygame thorugh a tutorial of flappy brid
And my bird on continuous rotation looks like that

[dawn quiver]

Traceback (most recent call last): File "/home/octane22/python/ursina_game.py", line 9, in <module> maze = Entity(model = 'mazeBeta', color = color.rgb(200,100,133), texture = 'brick', position=(0,0,0), rotation = (0,0,0), scale = (2,2,2)) File "/home/octane22/ursina/ursina/entity.py", line 105, in __init__ setattr(self, key, kwargs[key]) File "/home/octane22/ursina/ursina/entity.py", line 201, in __setattr__ m = load_model(value, application.asset_folder) File "/home/octane22/ursina/ursina/mesh_importer.py", line 66, in load_model if compress_models(path=path, name=name): File "/home/octane22/ursina/ursina/mesh_importer.py", line 192, in compress_models blender = get_blender(blend_file) File "/home/octane22/ursina/ursina/mesh_importer.py", line 163, in get_blender raise Exception('error: trying to load .blend file, but no blender installation was found. blender_paths:', application.blender_paths) Exception: ('error: trying to load .blend file, but no blender installation was found. blender_paths:', {})

is the result i get from terminal

@tranquil girder

which is strange cuz i made the file

and saved it into the game folder

[tranquil girder]

It finds the file, just not Blender, which is needed to convert the file. It should use the which blender command to find it automatically.
It's possible to give that path manually with application.blender_paths['default] = Path('path_to_blender_executable')
Or you can export manually from blender, as .obj or .glb.

[dawn quiver]

so i gotta type that

application.blender_paths['default] = Path('path_to_blender_executable')

right

[fervent herald]

U making blender addon?

[tranquil girder]

Yes, but write the path to blender. Idk where you installed it

[dawn quiver]

ok i will

how can i see where i installed it

[fervent herald]

Program files

[tranquil girder]

He's on linux lol

[fervent herald]

Blendee foundation

[dawn quiver]

i mean the linux command

[fervent herald]

Oops

[tranquil girder]

which blender maybe? But then I don't know ursina wouldn't find it

[dawn quiver]

doesnt even bring anything

up

lmao

il try find blender

no such file or directory bruh

i dont know the full name of my blender file

how am i supposed to find it

[tranquil girder]

open blender and look at the terminal. it probably will give you a hint

[dawn quiver]

python terminal for blender yeah ok

wont copy and paste for some reason

blender-2.93.5-linux-x64/

i think this is the name

when i try open it through linux thats what i see

[tranquil girder]

doesn't look like the full path to me

[dawn quiver]

i dont know how to find it

or any idea of how 2

'error: trying to load .blend file, but no blender installation was found. blender_paths:', {})

how can it not see my blender

[dawn quiver]

u can get blender on a chromebook???

[dawn quiver]

yeah

download tar file from the website for linux

locate file

do tar -xf (name of blender file and location)

oof

[dawn quiver]

i literally cannot find a solution to the error

or find the path

@tranquil girder what would u do to find the path

[tranquil girder]

I'd google how to find the location of programs on gentoo linux

[dawn quiver]

i googled that but i tried the 3 options i found and they dont work

search path

file names to search

dont work

and the other one is bs

i havent found the path but i found out that my file is in the correct location for ursina to run

File "/home/octane22/python/ursina_game.py", line 9, in <module> maze = Entity(model = 'mazeone', color = color.rgb(200,100,133), texture = 'brick', position=(0,0,0), rotation = (0,0,0), scale = (2,2,2)) File "/home/octane22/ursina/ursina/entity.py", line 105, in __init__ setattr(self, key, kwargs[key]) File "/home/octane22/ursina/ursina/entity.py", line 201, in __setattr__ m = load_model(value, application.asset_folder) File "/home/octane22/ursina/ursina/mesh_importer.py", line 66, in load_model if compress_models(path=path, name=name): File "/home/octane22/ursina/ursina/mesh_importer.py", line 192, in compress_models blender = get_blender(blend_file) File "/home/octane22/ursina/ursina/mesh_importer.py", line 163, in get_blender raise Exception('error: trying to load .blend file, but no blender installation was found. blender_paths:', application.blender_paths) Exception: ('error: trying to load .blend file, but no blender installation was found. blender_paths:', {})

took a look at the error message and i dont find anything

whereis blender just brings up blender

find doesnt work

i have no idea how to do this ive been googling

[tranquil girder]

how do you open it then?

[dawn quiver]

i type cd Desktop

then cd blender-2.93.5-linux-x64

then ./blender &

[tranquil girder]

oh, you know where it is then

if you cd to it

[dawn quiver]

so its inside cd blender-2.93.5-linux-x64

now i somehow make sure ursina can see that

how tf am i supposed to do that

[tranquil girder]

it would be something like "/home/Desktop/blender-2.93.5-linux-x64/blender"

if you're not sure what file paths are, I suggest you learn about that first

[dawn quiver]

damn so i gotta put that into the code or something

i will cuz it will probably help with linux

and im a noob at using linux

and file management and shit

[tranquil girder]

yes, read my first answer

if you don't want to set it up you can export to obj manually instead

but that not fun if you have to do it often

[dawn quiver]

what bout exporting obj

do i just convert the file format and slap it on the end of "mazeBeta"

[tranquil girder]

you export it from blender

[dawn quiver]

ok i will do that

il just watch a vid on how to do that first 🙂

[dawn quiver]

holy shit i did it im so happy

turns out i was ticking the wrong options when saving lol

and python can finally read the files

im so happy

[dawn quiver]

change the folder name or move the file with mv

Its solved

De

[soft bison]

Hi I am looking for help. I have created a snake game but for some reason the body parts are not showing except the tail. It did work previously and all the files are in the same folders.

All the other functions of the game work it’s just this final issue.

Any help would be great thanks

[steel lintel]

Hi I was wondering if it was possible to have multiple eg. "self.rect = self.image.get_rect(midbottom = (self.x, self.y))" for my sprites based on key conditions?

in pygame ^

[sharp crest]

'

[dawn quiver]

thats true

[dawn quiver]

@steel lintel wdym

Like a different shape every different key?

Or different parameters

[steel lintel]

okay so basically I have a sprite

which ive put into a class

but i cant seem to be able to move it to the left and right

so i was wondering that if i used a conditional of key presses which would change its getrect position it would move

but it doesnt seem to working

and now im stuck on what to do

[dawn quiver]

Well u slap in a key bind to change the parameters

That r variables

[steel lintel]

wdym?

keys = pygame.key.get_pressed()
if keys[pygame.K_a]:
self.rect = self.image.get_rect(bottomright = (150, 700))
elif keys[pygame.K_d]:
self.rect = self.image.get_rect(bottomright = (450, 700))
else:
self.rect = self.image.get_rect(midbottom = (self.x, self.y))

this is how im trying to change it currently in my class

[dawn quiver]

i dont know how to use pygame but if i understand what u are trying to do it seems correct

so with the a and d keys ur changing the position of the rectangle

maybe do more then just bottomright

and add like top left, top right, bottom left.

worked for me when i made a game where u moved a rectangle

[steel lintel]

my sprite just doesnt move

and idk why

[steel reef]

hi

[tough kayak]

my first game project

[dawn quiver]

Nicebro I'm doing my first 1

Stuck on blender models lil6

Llol

Lol

[dawn quiver]

sadly i want to but my pc dont support

[shy remnant]

i'm using blender game engine as my game dev software do you think it's a good idea?

it supports python

[tranquil girder]

upbge? I'm sure at least someone here approves ;)

[potent ice]

If it works, it works 😉

I'm not that familiar with it, but I assume it has advantages and disadvantages like any other game library or engine.

[candid mica]

hello

im trying to develop something and dispoay overlay text but struggling to do this easilly and re-usable

tried this simply and stupidly :

import tkinter as tk

root = Tk()
frm = ttk.Frame(root, padding=10)
frm.grid()

def text(n):
    ttk.Label(frm, text=str(n)).grid(column=0, row=0)





text("starting in 5sec")
text("other text")

I found this example on the web which jsut puts random letters & colors, but im struggling to refactor it into a re-usable function throughout my big script

:

import tkinter as tk
from random import seed, choice
from string import ascii_letters

seed(42)

colors = ('red', 'yellow', 'green', 'cyan', 'blue', 'magenta')
def do_stuff():
    s = ''.join([choice(ascii_letters) for i in range(10)])
    color = choice(colors)
    l.config(text=s, fg=color)
    root.after(100, do_stuff)

root = tk.Tk()
root.wm_overrideredirect(True)
root.wm_attributes("-transparentcolor","white")
root.geometry("+512+312".format(root.winfo_screenwidth(), root.winfo_screenheight()))
root.bind("<Button-1>", lambda evt: root.destroy())

l = tk.Label(text='', font=("Arial", 30))
l.pack(expand=True)

do_stuff()
root.mainloop()

[noble wave]

I made 2d minecraft lol

[exotic laurel]

Procedurally generated terrain?!

That's pretty cool

[noble wave]

I could have yes

but

I made it

random

[exotic laurel]

ahh I see

[noble wave]

I could have uses noise

that would have been easier

[exotic laurel]

Yeah that'd be a nice addition

pretty cool still

[noble wave]

But, yes, kind of procedurally generated

I took the long way

Cause i didnt get expected results

[exotic laurel]

mhm

[shy remnant]

yes

[dawn quiver]

Hey, pretty new to all of this. Anyways what do yall use for making games? I want to make a 2D mobile game and I've heard good things about kivy and kivent, so that's what I am learning rn. I'd like to know though if there are alternatives/better options? Thx in advance.

[green plover]

cool

[dawn quiver]

I want Maker a app like discord, and i need a little helppp

Dm me If you want help

[dawn quiver]

U can make some pretty sick creations with blender

Also question: if I want a ui stylised for a medieval RPG game what would u guys recommend

Pygame perhaps? Idk how to use anything but ones that dont work so preferably not 2 hard to learn

[dawn quiver]

Why is this game dev channel so creepy. Sometimes when I work on pygame projects, I see pygame stuff here. And just now, I'm working on a tkinter project, and what do I see: Tkinter projects!

[dawn quiver]

uh i need help

with a pygame game

[dawn quiver]

wait what

how

[shy remnant]

there is a game engine for blender it was scrapped

but there is a remake addon

called UPBGE

which what i'm using

[dawn quiver]

huh

I thought it was only for modeling

[shy remnant]

you can even turn it to photoshop

with tricks.

it's even for 2D animations. and more

it's a one man army software

[dawn quiver]

3d game with python?

[shy remnant]

yeah sure

[dawn quiver]

sounds impossible

[shy remnant]

haha

let me show you with a vid

[dawn quiver]

gotta try it fr

[shy remnant]

here is a example, this is a test for a game i'm making

made the quality low res so i can send it without discord telling me i need a nitro boost or something

• it's open source!

[dawn quiver]

damm I really need to try that, I was gonna start learning C# just so I could make games with unity, but now that I can make them with python its perfect

[shy remnant]

yeah this software is cool

you can program also with c++

[dawn quiver]

theres animation and python integration and integration with engines

[dawn quiver]

yeah u can make cool 3d games with python believe it or not

[viscid coyote]

              running=False
          
          if event.key== K_UP:

              draw_block()
        
        elif event.type==QUIT:
            running=False```

why is the block not moving

[grave vigil]

Maybe a little more context? Dumb questions aside (like, “Are you pressing the keys?”) are your enums correct? What’s in draw_block()?

[shrewd light]

this blows my mind i have no idea how you made this whats the game about anyway

[spice tide]

sry managed to do it

[stone marsh]

Hello everyone, i'm completely new to python, i want to try to make some Simple games on my mobile (i mean use qpython on mobile to make games on my android) first question - is there any tut that gives me def. of all commands other than built-in qpython help()?

It's pain on mobile to learn from scratch

[lunar venture]

Another helpful built-in function is dir() which returns a list of the attributes the object you pass it has

And, obviously, print() which prints text on the screen (if you pass any object that's not a string it will try to call its __repr__() method, or __str__() if the former is not available)

Other than that, learn the basics somehow and learn kivy which I know is included with QPython

[arctic seal]

Howdy to all! Please help me with virtual environment on python. I can create venv and use this without python on other PC on windows? (Sorry if the chat doesn't work with)

OwO i'm stupid cat, i guess. python.exe in folder scripts. I don't need any more help

[arctic seal]

And no, for some reason it didn't work out for me, damn it

Another PC all the same, somehow trying to get python from my folder

[dawn quiver]

people that say "OwO" should not be allowed into this community

change my mind

[upbeat hollow]

agreed lol

[dawn quiver]

furry aswell

[arctic seal]

You think that people should be allowed into this community who, instead of helping, point to a smiley?

Does communication style matter at all?

[dawn quiver]

if only you knew what others think bout furries/people who act like them lmao

anyway not the right channel for this pce

[arctic seal]

I'm from a non-English speaking country at all

[arctic seal]

I don't think I said something wrong. Tell me, which channel can be suitable for this question?

[dawn quiver]

just dont say OwO please its so cancerous

[arctic seal]

why it's cancerous?

[junior kelp]

how can i make my py file into a exe file

[light vessel]

please opinion on my game https://github.com/adammaly004/Gravity_run

[arctic seal]

pyinstaller

Look here: https://www.pyinstaller.org/

But in short:
pip install pyinstaller
pyinstaller "py_file_directory"

You can also put a flag, for show console:
pyinstaller --console "py_file_directory"

You can find the finished file with secondary along the path: "C:\Users\%user_name%\dist"

[junior kelp]

how to add a switch for my weapon animation

[plucky mural]

a auto writer

[royal hawk]

I might be asking for too much here, but is there a game dev package / framework (of any language) that:
1. Lets the user define an exposed event loop, letting the user handle everything, that follows the syntax of while True: for event in pollEvent()
2. Does NOT come from SDL2

[normal silo]

SFML

[potent ice]

You can define your own main loop in pyglet if needed

while window_open:
    clear screen
    pull events (triggers window and input callbacks)
    draw stuff
    swap buffers

That's also possible in arcade

BUT.. you of course need to be in charge of framerate pacing and a few other things.

[round obsidian]

@royal hawk Motion seconded on Arcade/Pyglet

[royal hawk]

does the "pull events" section allow for even more customization?

[royal hawk]

and is it also the same in arcade?

[potent ice]

What kind of customization? You can define callback functions for each event type

This is standard across most windowing libraries

If not all

Arcade is using pyglet so the approach should be the same for both I think

@royal hawk

[royal hawk]

you can bind custom functions to each event type? Can you show a small snippet of how that works?

[potent ice]

You can just assign callable to each event type as long as the signature is correct

[potent ice]

window.event(on_key_press_func)
window.event(on_key_release_func)

As long as the func passed is a callable accepting the right parameters it will be fine

[royal hawk]

Oof, thanks a ton lot!

[potent ice]

@royal hawk ```py
while blah:
window.dispatch_events() # triggers inout and event callbacks
<draw stuff here>
window.flip()

You can look at my pyglet wrapper in moderngl-window as a reference : https://github.com/moderngl/moderngl-window/blob/master/moderngl_window/context/pyglet/window.py#L64

Just be aware that you might get 3000 fps unless you force enable vsync or add some throttling using perf_timer

There might also be things like joystick/gamepad input that would need special handling with custom loop

@royal hawk What's the reason for needing custom loop just so I understand you better. I do use both depending on the situation.

You might be looking at something close to this. Not saying you need to use it, but it shows the simplicity of just using custom main loop and assigning functions to various callbacks : https://github.com/moderngl/moderngl-window/blob/master/examples/custom_config_functions.py

In pyglet, even if you do have the default callbacks in a window subclass you can use push_handlers(..) to move the callbacks to other modules/classes temporarily

It's a fairly flexible system

You could also use plain glfw, but that assumes you are doing all the low level rendering yourself. Pyglet have A LOT of things built in making your life a lot easier. Batches, shapes, sprites, media player, resource loading etc etc

[potent ice]

Have you looked at everything linked in #welcome ?

[snow hill]

Hi,

I was unsure if this is post was better suited for this gamedev channel or rather for the data science but here we are... as science visualization & robotics are using more and more gamedev technologies nowadays...
Anyway, I'm glad to share this project here, as our team is working on improving the rendering quality of digital twins, especially for Python developers.
Our first attemps was on the Poppy Ergo Jr, with a simple POC that shows how easy it is to both

• control a poppy from Python
• render a 3D twin of the physical robot and make it look as realistic as possible to match nowadays users expectations in terms of 3D HMI 🙂

The result can be found here :
https://github.com/harfang3d/python-digital-twin

Next items on our list :

• activate the compliance mode, so that manipulating the actual robot is reflected by the digital twin
• implement the next level of 3D digital twin, using our python VR API, this time on a far more elaborate robot, the "Reachy" 🦾

Ask me if you're not familiar with robotics notions, I'll try to explain as much as I can 🙂

(works on Windows & Linux)

[junior kelp]

nice

[still hedge]

so im interested in trying to make a tactical rpg, something sort of xcom-like. im kind of looking between pygame, kivy and arcade right now. it would be a top-down 2d sprite sort of thing, laid out on a grid. which one would you all say is best for that sort of thing?

[junior kelp]

how can i hide my object if a press a key

[safe spade]

hi, i was programming a game when i hurt a problem. For info i'm using ursina. The problem is the perfomance, ursina is not able to make big cumputation(i think). So anybody as idea to solve that or a another librarie for 3D game developpement.

[snow hill]

how did you diagnosed this computation issue?

is the framerate below 30 frames per second, for example ?

[snow hill]

probably pygame?

[safe spade]

no the frame rate is normal but i can't do big thing

which game engine do you use

[hardy kite]

is there any game jam for python rn

[junior kelp]

that now is running

[snow hill]

yes, you should look at the PyWeek gamejam 🙂

I'm not sure a Python discord server is the best place to get this kind of information 🙂
Sorry, I can not help 🙂

[cinder steppe]

UPBGEv0.2.5b-b2.79Windows64 used 2.4 to make but updated, 2.5b is really good so far, there is UPBGE-0.31-Alpha-Windows-x86_64 if you are looking for new features. it's on Linux64 and MacOS as well.

Hello everyone, I am planning to create a 3d game, but I don't want to spend time on learning blender and animations. Is there any place we can find free models with animations included?

[summer breach]

is unreal engine python included? im trying to make a game similar to phasmophobia

[past geode]

Hello! I am trying to make a 3d game using python, but stuck on which engine to use. I did some research and deemed Ursina and Panda3d to be the best one out there currently.

So, I was wondering which would be a better choice? It would help a lot if you gave some comparisons too! If you know something better, then that'd be great too!

Hi, I want to start making a game that uses midi as an input. so does anyone know of a good python library for midi inputs?

[dawn quiver]

Can someone help i have been using python for while now , and i was following a tutorial about making the pong game, and when i was coding the ball movement i used this code:
# Move the ball
ball.sety(ball.ycor() + ball.dy)
ball.setx(ball.ycor() + ball.dx)
And when i run the game it give me an error
btw the error is:
ball.sety(ball.ycor() + ball.dy)
AttributeError: 'Turtle' object has no attribute 'dy'
Press any key to continue . . .
Can someone help me?

[rocky path]

something like this? https://www.pygame.org/docs/ref/midi.html

[barren torrent]

so I've got some questions about good... I wouldn't call this "game design" exactly, but... I am approaching a system within the game's architecture and pondering the best options for how to pull it off with code logic...

AHEM.

So, I am currently converting an ancient MUD based on ye olde CircleMUD 3.5 to modern Python.

And, in studying it, I realized it has some interesting features and ways of handling them.

For instance, most game entities - such as NPCs/player characters, rooms, items, etc, have "flags" that alter their behavior. And in the case of items, items have an "item type" which is effectively an enum (is it a container? a weapon? clothing? a drink container? something edible?)...

Under the hood these are just tracked as things like a set() of numbers for the flags. the NAMES of those flags are stored elsewhere in the C code as simply an array of strings that it can refer to if it wants to display it...

I'm wondering how I might improve upon this design. What other approaches there are for breaking down the things that define game content's traits. The properties of items or NPCs and so on.

are there any good resources on this subject?

[proper peak]

You could use enum.Flag in Python as a way to have a bunch of named properties that can be combined and stored as an int.

not sure what would be the best way to move away from such an approach entirely

[barren torrent]

well

I can't actually change the ARCHITECTURE for this conversion at this point.

But I'm wondering about the best ways to handle the relational aspects - to create something which represents the flag, and then be able to serialize/deserialize etc

*examines enum.Flag

[proper peak]

If you're not worried about efficiency too much, you could outright have each property be a boolean attribute - then (de)serialization can be done with JSON.

[barren torrent]

eww IntEnum not so hot...

I'm probably gonna have to do something like....

@dataclass_json
@dataclass
class Flag:
    num: int
    name: str

And then create a container of these things. load them from a JSON file...

You have several ways:

• old method: save your background behind the text before you draw it so that you can clear the text and restore what’s behind
• immediate method: clear all then redraw what’s needed, all the time

[trim meadow]

so i am doing code combat game development 2 i do not know what is wrong with this code

Destroy at least 50 defeated ogres.

This spawns and configures an archer.

def spawnArcher(x, y):
archer = game.spawnXY("archer", x, y)
archer.behavior = "Defends"
archer.attackDamage = 20

This spawns and configures an ogre.

def spawnMunchkin(x, y):
ogre = game.spawnXY("munchkin", x, y)
ogre.behavior = "AttacksNearest"

Spawns some archers in a row.

def spawnArcherWall():
spawnArcher(30, 12)
spawnArcher(30, 23)
spawnArcher(30, 34)
spawnArcher(30, 45)
spawnArcher(30, 56)

Spawns an ogre wave with a random offset for variety.

def spawnOgreWave():
offset = game.randomInteger(-6, 6)
spawnMunchkin(80, 16 + offset)
spawnMunchkin(80, 22 + offset)
spawnMunchkin(80, 28 + offset)
spawnMunchkin(80, 34 + offset)
spawnMunchkin(80, 40 + offset)
spawnMunchkin(80, 46 + offset)
spawnMunchkin(80, 52 + offset)

def onDefeat(event):
unit = event.target
# Increase the game.defeated counter by 1.
game.defeted+=1
# Use unit.destroy() to destroy it.
unit.destroy()

Set "munchkin"s "defeat" event handlers to onDefeat.

game.setActionFor("munchkin", "spawn", onDefeat)

game.defeated = 0
game.spawnTime = 0

Add a manual goal.

goal = game.addManualGoal("Defeat 77 ogres.")
ui.track(game, "defeated")

def checkSpawnTimer():
if game.time > game.spawnTime:
spawnOgreWave()
game.spawnTime += 1

def checkGoal():
# If the game.defeated counter is greater than 77:
game.defeated > 77:
# Set the goal as successfully completed.
game.setGoalState(goal, True)
pass

[oak narwhal]

Is there any stable gui automation library?

[warped dove]

what's a good 3d game engine for python?

cause someone said it to me Ursina engine is both 2d an 3d

[narrow radish]

pyautogui?

[oak narwhal]

It seems pyautogui can't find and target a specific window

[narrow radish]

you should look into platform specific stuff then, I know windows is really good for that stuff (good builtins)

linux not so sure, your wm might be able to help you out, otherwise there's always X

[oak narwhal]

👍

[narrow radish]

Is there a specific use case you have in mind?

[narrow radish]

curious what you're trying to automate

[oak narwhal]

I 'm working on a "cloud desktop" project. Some bugs will cause no video input in the client side after about 20mins operations.

So I don't want to operate for such long a time. Need some automations

[narrow radish]

Huh interesting

Strange that you get bugs after 20 minutes

Is it that the screen saver is kicking in or something haha

no idea what would cause that

[oak narwhal]

I haven't found the reasons 😦

I have worked on it for one week but without any progress. If I didn't solve it this week, my boss would get angry I guess.🤣

[narrow radish]

Oh it's for work

Don't have much of a choice then

[oak narwhal]

Yes. I will go back to work. Thanks for answering:)

[sinful slate]

@late spindle do you mean the combined motion that makes it go once sideways once down or up ?
in a slope

[sinful slate]

not a glitch, you coded it lmaooo

[late spindle]

thanks for laughing at me

but that actually made it better because it used to do the glitch in both dimensions

with that I could move diagonally without wiggling around

@sinful slate

[tranquil girder]

you should get the input direction as a vector2
normalize it, so it's inside a circle and not a square, so you don't move faster diagonally

and then you add that to the velocity

[late spindle]

will that also fix the wiggling issue

[tranquil girder]

yes

[late spindle]

i’ll try it when I get home

but how would I even do that

this is one of my first times using pygame

[tranquil girder]

https://www.pygame.org/docs/ref/math.html#pygame.math.Vector2

[late spindle]

right now I did this py self.acc.x = pygame.math.Vector2(1, 0).normalize() I'm assuming this is wrong usage because it crashes when I try to use it must be a real, number not pygame.math.Vector2

[proper peak]

pygame.math.Vector2(1, 0).normalize() is a vector, so what do you expect to happen when assigning it to a component of a vector?

[late spindle]

to change the values of the vector lol

[proper peak]

well, assign to acc then (the entire vector), not to acc.x (a single component)

[late spindle]

oh ok

[proper peak]

pygame is actually being really good here by throwing an error immediately, rather than allowing you to do this and throwing an error later when you try to do operations with that corrupted vector

[late spindle]

Ok thanks

Do you know how to help me fix this glitch tho

1 sec

and I cant move vertically lol

[proper peak]

What you want to do is to take a zero vector, and for every direction the player presses, add/subtract one to the correct axis of that vector.

then normalize the vector and assign to the player's acc.

(This is in fact a very common pattern in simple games like this)

[late spindle]

isn't that what I already have though

[proper peak]

No. Your acc always ends up a vector in one of the cardinal directions (the direction among the pressed ones that you check last).

while using that pattern, you can end up with a diagonal vector, too.

[late spindle]

Oh you think the character shouldnt be able to go sideways

yeah maybe thats a good idea

[proper peak]

huh?

[late spindle]

I don't get it

[proper peak]

What you are currently doing can never result in diagonal motion.

the way I'm proposing can

[tranquil girder]

you can use the variables left_axis, up_axis and so inside the vector2

for x it would be right_axis - left_axis

and do the same for the second value in the vector2, but with up and down

[late spindle]

these are those values though left_axis = pressed_keys[K_LEFT] or pressed_keys[K_a] or pressed_keys[K_q] or pressed_keys[CONTROLLER_BUTTON_DPAD_LEFT]

[tranquil girder]

convert it to a float or int then

[late spindle]

this is just when a key is pressed

[tranquil girder]

yes, exactly

here's an example from my 3d game

different engine, but you get the point hopefully

[late spindle]

oh ok

I'll try that

ok so I did this ```py
self.acc = vec(int(right_axis) - int(left_axis), int(down_axis) - int(up_axis)).normalize()

It works :)

[tranquil girder]

yay :)

Does this video achieve the criteria?

[ebon birch]

Yes

It looks really good

[oblique aspen]

for pygame do i really need to know a ton of advanced mathematics like the quadratic formula or stuff like that

[opal thorn]

More math allows for games that require more math

If you're making a card game, you likely aren't calculating trajectories and dealing with AI pathing

[oblique aspen]

alright, thanks for the basic rundown, much appreciated.

[cold storm]

matrix math is handy for parenting type relationships

in 2d and 3d

modulo is handy all over the place

so is sine() and dot()

cross() is useful, but less useful then most of the other math
