Hello, please don't use our server as an advertisement board. Thanks

[torn jackal]

hey guys how can i just show 2 numbers after the . with this code : TimeSurf = fond.render('Total Time : %s' %total_time, True, (255, 255, 255))

[surreal orchid]

hey all. Don't suppose anyone has experience with programming a kinematics/projectile program? I'm trying to get the output window to draw the projectile while deleting the previous iteration of the projectile, rather than drawing the whole path over and over with a slight increase in the position in the x and y direction.

[proper peak]

Are you using matplotlib or something like that?

[surreal orchid]

nothing like that no, I'm not using any sort of libraries

I'm trying to just use math and tkinter

I'm trying to find a decent example of 2d projectile motion without using pygame or matplotlib but its pretty hard to find

[grand matrix]

ah yes. Indentation. My biggest weakness. My mortal enemy. Thanks alot ig

[broken citrus]

happens

[proper peak]

Then it seems to me like all your should need is to change the position of the GUI element representing the projectile.

Or are you drawing manually on some kind of tkinter-provided canvas? In that case redrawing the path might be unavoidable.

[surreal orchid]

Yeah I'm using tkinter

And the canvas command

[broken citrus]

if the bullet is stored you can just delete it after certain amoutn of time

[surreal orchid]

My thought is while writing pseudo code, that I'd have to work out new new position, store that value, then have tkinter draw the circle based on those values

And then work out the newer values, store those, draw another projectile and delete the previous projectile

[broken citrus]

im busy rn so maybe someone will help you

[surreal orchid]

Tbh I don't think I'll get it done by tonight, so drained dealing with my father in laws passing this week.

[proper peak]

If I'm reading the docs right, tkinter's canvas is a "smart" kind of canvas in that it stores each drawn thing as an object and you can modify/delete them.

[surreal orchid]

Oh that could potentially make this more doable then

[proper peak]

So all you should need is to store the handle it gives you when you draw the ball for the first time, then change its coords each frame and tkinter will redraw it.

the "Modifying Items" section in https://tkdocs.com/tutorial/canvas.html mentions that, at least

[surreal orchid]

I found a pretty interesting example on assignmentreport.com

👍

[grand apex]

Anybody know of any non linear text based games or got any ideas for one? A text based roguelike would be more interesting. Also any game that could be adapted into a text based game such as blackjack etc would be cool

[odd stone]

anyone know why my random.randint() function is only picking 3 out of 760 numbers this is my code: def ItemMovement1(item):
if item.rect.y == 0:
item.rect.x = random.randrange(20,780,5)
item.rect.y += 4
if item.rect.y == 800:
item.rect.y = 0
bar.lives -= 1
# 8 rectangles are each givin different x values but only 3 of them are showing so im guesing that the other items have the same x value
if item.rect.colliderect(bar.rect):
item.rect.y = 0
bar.points += 1

[cold storm]

I feel this goes way beyond a flow map

[tranquil girder]

Where are you using randint()? I don't see it

[odd stone]

Oh sorry it was where randrange was and it didnt have the 5

[sinful lodge]

woah is that some blender shader thing

[twilit quail]

you think scripting in godot is better than developing on pygame?

[cold storm]

geometry nodes @sinful lodge

[sinful lodge]

ah nice... i dont understand blender at all

[cold storm]

it's like an ubber py environment for 3d content creation

[potent ice]

Very subjective and depends on what you are making.

[quick dove]

for random events I assign a precentage to a certain event, but how do I choose which event to trigger

[torn jackal]

hey guys how can i just show 2 numbers after the . with this code : TimeSurf = fond.render('Total Time : %s' %total_time, True, (255, 255, 255))

Because it shows me something like that : 29.999999999

[torn jackal]

Oh thanks man

Thats working

[torn jackal]

My game soon on PlayStore ! Tell me what you think about it !

[summer parcel]

Can you develop games with python?

[tranquil girder]

Yes

[torn jackal]

@summer parcel of course 😂

And the most used library is named Pygame

[elfin sun]

Is there a library to make it online multiplayer

[elfin sun]

What language did you make it in

[torn jackal]

Python

Pygame

[burnt sigil]

Yup, you can use Pygame, or Arcade libraries for that. I would recommend Arcade, since it is more modern and easier to work with.

[torn jackal]

Thats true that when u begin to use Pygame un games wont be really beautiful but i can promise u that un games become really nice really fast !

@burnt sigil but i think that Arcade is also really good

[pale wedge]

Hi!
Been doing a simple Monopoly as training (I'm a beginner) and I really wanted to show it here
Is there any problem about that?

Ah crap
It's over 2k characters long
Nvm :(

[agile sage]

what is the best modules to build games on python

I look a recommendations

[odd stone]

pygame is pretty good

[keen dew]

^^

one of the best, if not

[odd stone]

How do i change the layers of Sprites in pygame. i have a rectangle and some text in the same place but the rectangle is on top and i want it on the bottom. also im using pygame

[frank field]

Pasting large amounts of code

If your code is too long to fit in a codeblock in discord, you can paste your code here:
https://paste.pythondiscord.com/

After pasting your code, save it by clicking the floppy disk icon in the top right, or by typing ctrl + S. After doing that, the URL should change. Copy the URL and post it here so others can see it.

[odd stone]

https://paste.pythondiscord.com/bibotovare

[burnt sigil]

I've found this 3D engine, and I'am going to tryy it out.
https://www.ursinaengine.org/

[torn jackal]

Ursina is good

[elfin sun]

If you made your cube game using pygame, then how can it be on Play Store

[torn jackal]

Thats ez

Just have to put all my files under the apk format

Then I put them in aab

And there we go my game is on Play qtore

[elfin sun]

What about the controls,

[torn jackal]

What do u mean

[elfin sun]

Controls are different in a pc and Android, so how did you manage that for android

[torn jackal]

Oh

I just created arrows to move

U can see it on the video

https://youtu.be/Lr6xwQSD69c

[elfin sun]

Hmmm, i didn't know you could add buttons in pygame

[torn jackal]

Actually we cant

😅

But i just used the colllidepoint function

[elfin sun]

Oh

[torn jackal]

U know that ?

[elfin sun]

Heard about it but never used

[torn jackal]

Collidepoint detects when u click on a surface

[elfin sun]

Hmm yeah that can be used for it

[torn jackal]

Ye oc

But i did a version for the computers too

With using the arrows of the keyboard

[elfin sun]

And did you use tiled for the level

[torn jackal]

What is "tiled" 😅

Sorry fr people are bad in english

[elfin sun]

It's just a level creater which can be used in pygame

[torn jackal]

Oh no

I created a function to create random levels

[elfin sun]

You can make maps in it

[torn jackal]

I didnt know that ...

[elfin sun]

That would work better in your case

[torn jackal]

Yes i think so

[elfin sun]

Is there a video on yt to do this

[torn jackal]

Mmmh

Actually aab is a New format

So u can find videos on apk format and then put your apk in aab

But put your programm in aab xithout put it in apk before

I dont think it s possible for the moment

[elfin sun]

I'll try that if it works because my game has a ton of different files

[torn jackal]

If u want to put your programm in apk, you have to use buildozer

[elfin sun]

That's for kivy only right?

[torn jackal]

No

Actually i can put my game in apk

Even if the program is not using kivy

[elfin sun]

It would be very helpful if that's possible

Last time I made a game using kivy, buildozer kept raising an error at the last step

[torn jackal]

U were on Windows right

?

Bc you need to be on Linux or osx to use buildozer method

I know thats strange...

[elfin sun]

I was using Google colab

It uses Linux

[torn jackal]

Mmmmh

Maybe that u didnt do the good procedure

[elfin sun]

What's that

[torn jackal]

Buildozer init
Buildozer android deploy run

U wrote something like that?

[elfin sun]

After the first one, I ran the debug command

to get an apk

[torn jackal]

Yes

Then ...

U got an error

[elfin sun]

But it was different, limme see

[torn jackal]

Show me please

[elfin sun]

It was buildozer -v android debug

[torn jackal]

But what was ur error

[elfin sun]

I don't really remember, cuz i did it alomost 2 months ago

Maybe I can find it in my history

[torn jackal]

Was it check configuration tokens

Then unkown command target android

[elfin sun]

I don't know what that means

The error shows something like
Running cythonize failed

[oblique violet]

shesssh

[mortal dust]

sus

[oblique violet]

hi im new here

i want to make a minecraft python but idk where to start

[dawn quiver]

you might want to take a look at the Ursina engine

!pypi ursina

[frank field]

ursina v4.1.1

An easy to use game engine/framework for python.

[oblique violet]

thanks

is there any tutorial?

[dawn quiver]

this video looks interesting

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

[oblique violet]

thanks

:D

[dawn quiver]

it's not exactly a tutorial

[oblique violet]

like tutorial for beginner

how to start

and the basics

[dawn quiver]

not sure on that, you're gonna have to go by the docs

[brave elm]

you will be surprised to know how simple ursina engine actually is

@oblique violet

[oblique violet]

lmao

thanks

[rapid barn]

How can I make a game multiplayer

[rapid barn]

I'm trying to make a multiplayer red light green light

but I don't know how to make it multiplayer

[broken citrus]

sockets

[limpid lodge]

Hi i'm new but good at python

what should I make for py

[left beacon]

Hi, I got a problem with collidepoint, I want to remove an item from a list (by index) when clicking on it, yet it removes all of them like Im turbo clicking on the same spot

how do I fix this?

[left beacon]

how do I make the event.type == pygame.MOUSEBUTTONDOWN be valid for only 1 frame?

[left beacon]

solved it by adding a time.sleep(0.1)

[oblique violet]

how do i install ursina without powershell
cuz my powershell is not working
can i download it with command prompt?

[dawn quiver]

It can be installed like any Python library, just like how you've installed the library for Discord bot

Simply have pip installed along with Python and you can install it.

[oblique violet]

so i can do pip install ursina in command prompt and get it installed right?

[dawn quiver]

As the documentation says, yep

[oblique violet]

thanks

[oblique violet]

erm

alright its working sry for the ping

just about to ask why is nothing loading

[oblique violet]

what game do u like to play?
you can try to remake it like me
im currently trying to remake minecraft

[dawn quiver]

I remember doing that

[oblique violet]

and a weird problem

from ursina import *

app = Ursina()
test_entity = Entity(model='square',color = color.blue)

app.run()
```but i only get the grey screen

[dawn quiver]

That I can't help, never used the engine

[oblique violet]

oops

np

i change it to circle and its working again

for square its call quad not square

[sinful lodge]

maybe becaude your camera isnt facing it

or your camera is inside of it

use EditorCamera() code to create an editor camera and move around the camera

[oblique violet]

u mean me?

[simple belfry]

hey so I'm working on collisions in pygame and I have a problem that for me is too weird to understand it.

class Tile(pygame.sprite.Sprite):
    def __init__(self, image):
        self.sprite = image
        self.rect = self.sprite.get_rect()

class Tilemap_set:
    def __init__(self, map:list):
        self.map = map
        self.tile_map = []

    def check_collision(self):
        global player
        
        for tile in self.tile_map:
            if player.hitbox.colliderect(tile.rect):
                player.get_hit()

here if Tile and fragment of Tile_map class. The player.get_hit method prints in terminal "wall" as you see whenever it collides with any tile. player has it's own rect defined in his class as self.hitbox. there is no errors and game runs, the tilemap is drew on to a screen, all drew tiles objects are saved to self.tilemap list, player can move etc. but when I walk into a wall, the player.get_hit method is not raising. Do you know what is wrong there?

[oblique violet]

alright new problem

this thing

from ursina import *
from ursina.prefabs.first_person_controller import FirstPersonController

app = Ursina()

grass_texture = load_texture('urcraft/grass_block.png')

class Voxel(Button):
    def __init__(self, position = (0,0,0)):
        super().__init__(
            parent = scene,
            position = position,
            model = grass_texture,
            origin_y = 0.5,
            texture = 'white_cube',
            color = color.white,
            highlight_color = color.lime)

    def input(self, key):
        if self.hovered:
            if key == 'right mouse down':
                voxel = Voxel(position = self.position + mouse.normal)
            if key == 'left mouse down':
                destroy(self)

for z in range(16):
    for x in range(16):
        voxel = Voxel(position=(x,0,z))

player = FirstPersonController()

app.run()
```its pitch black when i run it

alright i know why

lemme try

[tranquil girder]

You're trying to set the model to a texture

[oblique violet]

what do i do to the texture = ...

[tranquil girder]

= grass_texture

[oblique violet]

ok

[tranquil girder]

you did model=grass_texture, you want texture=grass_texture

[oblique violet]

so model = grass_texture

and texture also?

[tranquil girder]

no, the model can't be a texture, it has to be a model

[oblique violet]

huh

what about model

[tranquil girder]

or the name of one at least

[oblique violet]

model = cube?

[tranquil girder]

'cube'

[oblique violet]

ok

what about the colour

[tranquil girder]

or actually, probably the model you made, since you're using a cusom uv mapped cube model

[oblique violet]

can i remove it

[tranquil girder]

what color?

[oblique violet]

color = color.white

and the highlightcolor = ...

[tranquil girder]

no, because the default color for Button is not white, but a slightly transparent black

[oblique violet]

ok

no wonder i got it all black

so what do i set it to

[tranquil girder]

It's multiplied with the texture's color, so color.white will have no visual effect

[oblique violet]

ok

alright

gg

[oblique violet]

help

whats this

why is it white

[tranquil girder]

it's a bunch of white cubes

look at the terminal, probably says texture not found

[oblique violet]

ya

how do i correct that

[tranquil girder]

that's not it

[oblique violet]

all the directory is here

[oblique violet]

huh

then what is that about

[tranquil girder]

something else that doesn't really matter

[oblique violet]

lol

then why is it that

there is no error

[tranquil girder]

try loading textures the way it's described in the documentation

instead of following a tutorial which does it the wrong way

so texture='grass_block' in your case

[oblique violet]

huh

grass_texture = load_texture('urcraft/grass_block.png')

[tranquil girder]

?

[oblique violet]

this is the whole docs about it

gg

[tranquil girder]

yes, because it's simple, just give it the name

[oblique violet]

?

what name

[tranquil girder]

like this

[oblique violet]

okok

no need .png?

[tranquil girder]

it's optional

[oblique violet]

ok

missing texture

[tranquil girder]

is it in the same folder or below as your script?

[oblique violet]

er

[tranquil girder]

that's a no

[oblique violet]

oof

[oblique violet]

what do i do ;-;

[oblique violet]

alright

thanks for the info

what on earth is this

@tranquil girder

[tranquil girder]

you're not using the custom model you made/downloaded, so the uvs are wrong

[oblique violet]

huh

how do i do it

[tranquil girder]

model = 'name_of_your_model'

[oblique violet]

=.=

class Voxel(Button):
    def __init__(self, position = (0,0,0)):
        super().__init__(
            parent = scene,
            position = position,
            model = 'cube',
            origin_y = 0.5,
            texture = 'grass_block',
            color = color.white)
```this is correct right?

[tranquil girder]

is your model named 'cube'?

[oblique violet]

i thought u told me to put it to cube

:/

so i change it to grass_block?

[tranquil girder]

and then I told you some more after, did you read that?

[oblique violet]

lemme read it again

[oblique violet]

huh

its not a uv mapped cube model

[tranquil girder]

I don't know what your model is called, so I can't answer

[oblique violet]

its just a png i downloaded on google

🤣

[tranquil girder]

a png is not a 3d model,. it's a flat image

[oblique violet]

maybe i need to draw it on my own

[tranquil girder]

a 3d model is something like a obj

[oblique violet]

oo

how do i do it

[tranquil girder]

https://www.youtube.com/watch?v=Yx2JNbv8Kpg&t=19s&ab_channel=FlippedNormalsMarketplace

[oblique violet]

thanks

[oblique violet]

u know any browser uv mapper?

[tranquil girder]

no, sorry
I use Blender

[oblique violet]

where can i download it

[tranquil girder]

blender.org

[oblique violet]

cuz sure i will get tons of real blender if i google it

[oblique violet]

thanks

[oblique violet]

but how large is it

[smoky stump]

Can smdy give me a link to a yt good tutorial for pygame

Plssss

[elfin sun]

There are some really cool tutorials of clear code on yt for that

[smoky stump]

I know him

[elfin sun]

Ooh

[smoky stump]

Yes

[elfin sun]

You didn't get anything on that channel?

[smoky stump]

I am not looking in his channel

I am only like know that channel

He explains it very crlearly

[elfin sun]

You can check out Tech with Tim, there's a good playlist of pygame in his channel

[smoky stump]

I know

[elfin sun]

Have you tried any of his tutorials

[smoky stump]

No

I think I will do it

[elfin sun]

Yeah sure go n check it out

[smoky stump]

Thnks

[elfin sun]

He has covered all the basics in his videos

[smoky stump]

Noice

Ok

Thnks

I will check it out

Bye

[elfin sun]

👍 😁

[sharp berry]

Heyy Guys Could Anyone suggest me complete roadmap to game development

[elfin sun]

There's not much opportunities in python except for some libraries like pygame, ursina but if you go with other languages like c or c++ sure you can do many things

[left jetty]

A game SE is an all-rounder the could create the entire logic for any type of app (finance/construction/ etc.) not related to gaming , from the start but less so with networks,servers,db , true ?

[frank field]

Hey @thin shuttle!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

[scenic dome]

Do you need programming or testing skills? If so I would be interested potentially.

[wind basalt]

we are mainly programming in c# actually

because our game engine only support c#

[sleek bay]

how can start python in step by step

I want the road map

[oblique violet]

idk how to use blender

[outer ferry]

anyone want to talk about game design? what are some good resources? thank you in advanved and sorry for my english

[oblique violet]

what kind of resource u want

python or game dev

[outer ferry]

either is fine thank you so much

if it is gamedev related i will want to read it. i love python

[oblique violet]

u learnt the basic?

[outer ferry]

yes I think i know the basics of python thank you

[dawn quiver]

Not sure if anyone is interested in joining a development team but if you like to develop games and want to make games under a dev team name dm me

[low horizon]

what're you guys using to make em

[dawn quiver]

Mostly python and might move to other languages if needed

[dawn quiver]

But really anyone with any programming experience can join

[hybrid burrow]

Hi, I use python for a long time (two years) and I think, is it the correct option for games.

Im learning Panda3d

[low horizon]

oh nice i havent really tried developing games with python

ive only tried with lua

roblox

[hybrid burrow]

But maybe, I should change to another language like Java or c#?

[dawn quiver]

Python isnt the best with games but can certainly be done

[hybrid burrow]

What about the job?

[dawn quiver]

I've sent you a friend request

[dawn quiver]

Job, referring to joing my dev team?

[hybrid burrow]

You have dev team?

[dawn quiver]

Yes

[hybrid burrow]

Professional or hobby?

[dawn quiver]

Not professional as of yet

[dawn quiver]

I hope that one day I can make a career out of this dev team but for right now me being 17 years old I cant

[hybrid burrow]

Yeap...

[potent ice]

It's better to keep things out in the open here. Do you have public organization/repository with a project for example?

If you are recruiting for closed source projects or some project with an unclear license you need to be very careful.

[dawn quiver]

anyone can join the discord server if they wanted to

i have a discord server setup for my dev team and the community

[potent ice]

You have any current projects and is the source open for everyone?

[dawn quiver]

i have no current projects with the dev team but by myself i have one available project on itch.io

[potent ice]

What will the license be for the new project you are starting?

[dawn quiver]

if by license you mean creator name it will be under Hyper Pixel

[potent ice]

Copyright / license for the source code.

Non-specified? MIT? GPL? BSD? Proprietary?

[dawn quiver]

im not really sure what it would be under or how to even license games

[potent ice]

When you are working with people in a team this is very important to establish from the start. Not having this sorted out is a huge red flag.

[dawn quiver]

if possible could you help me go through the necessary steps to licensing games?

[potent ice]

If the games are just for fun and learning the simplest solution is to use an open source license and work on the game in a public repository for example on github

For example MIT or BSD license meaning anyone can use the code

If no license is specified you can suddenly claim ownership of all the code and kick out the rest of the members and benefit from it commercially in the future.

That is actually not an uncommon scam

[dawn quiver]

well i dont want anyone who is not authorized to be able to use the code

[potent ice]

Ok. So you are basically recruiting for a private project then?

[dawn quiver]

I'm not sure

Honestly I just wanted a team to create games for a possibility of this becoming a job for me and the others who joined the team

[potent ice]

<@&831776746206265384> Can you look at this?

[dawn quiver]

Is it against the rules to invite people to join a dev team I created?

[fading whale]

Erm yep @dawn quiver in my opinion this counts as recruitment, so you shouldn't post it in this server without explicit permission from the admins (which is not usually granted).

[potent ice]

It would probably fall under recruitment rules here. You are recruiting people for a private project. The licenses and ownership is very unclear as well. I think it's better to just go open source

[fading whale]

This is in the interest of protecting members from scams, as well as preventing a large amount of potential recruitment spam.

We have to apply the rule evenly.

[dawn quiver]

I wasn't really sure where to go with the licensing honestly I just wanted to create games with other people, I'm sorry for breaking the rules...

[potent ice]

MIT / BSD licensed open source games in public repos is much better 🙂

[fading whale]

If you have already established a personal relationship with other members of the server, and wish to invite them to work on something with you, that's obviously your own business. But putting out a general message about paid work counts as recruitment (even if it's a partnership).

[dawn quiver]

Oh no you got it wrong I'm not creating a paid business as I'm only 17 and have no real way to pay others and these people have agreed to work for free and to try and prevent scams I did interviews to make sure I wouldn't get scammed

But since I did break this recruitment rule what are the consequences?

[fading whale]

Erm, me telling you not to do it again 😄

[dawn quiver]

Ok got it, and you got my word on that

[potent ice]

To get you in a little less trouble in the future.. do read about licensing and discuss this with whatever team you have. You can get in a world of trouble not establishing this from the start. Who owns the code? You? Everyone? Can other members fork the project and go their own way?

[dawn quiver]

Ok I'll talk to my team abt it, there's only one member that I've made really good friends with

Hello guys

Which Python Game engine would be the best for a python Beginner

[sinful lodge]

none, get a good grasp of python first

[burnt sigil]

first, learn the data structures, functions, classes, data types etc. then write simple text-game, only then try to use game-engines. I think that Arcade is the easiest one to start with after you learned the basics.

Hey guys i wanted a help in a help in a program

and i want to detect its collision with the circle boundaries

is there a way to jump to a certain point in the code right at the start? for example, i run the code, the code read a json with some variables, and then it jumps to the line 50 of the code

[potent ice]

You need to design your program with that in mind.

You can't jump to line numbers, but you can neatly split up your code into functions/classes etc

[hot willow]

Hey there. My Pygame framework has had a pretty annoying issue for some time now. If a game object is destroyed (removed from mem) nearly right after it is spawned, sometimes the sprite wont delete. The object is removed completely from mem, but its sprite will remain in the sprite group. I have explicit instruction to remove sprites from all the group on destruction, and yet it stays. I will post the code in 1 second

not the code, but here is a video of what happens. The enemy shoots his bullet on (what I believe is) the same frame the game reloads the level. Reloading the level destroys all game objects. Clicking on the sprite shows that it is not a live game object too, as I have it so all game objects print info when clicked on. I can also print all objects, and there will be no bullet

This is the sprite code, it is a separate class from game objects.

class Sprite(pygame.sprite.Sprite):
    def __init__(self, parent, sprite, rotation, scale, layer: AbstractGroup) -> None:
        super().__init__()
        self.parent = parent
        self.layer = layer
        self.sprite = sprite
        self.scale = scale
        self.rotation = rotation

        #Unrelated Init stuff happens here
 
        #add sprite to sprite layer
        parent.pde.display_manager.group.add(self)

    def deconstruct(self):
        self.kill()
        del self

This code definitely gets ran under normal circumstances, otherwise all the sprites would linger on level reset. It's specifically when a sprite gets deleted very close to object creation. It disappears after because I also have explicit instruction to restart the display manager on game reload, which deletes the sprite properly, but it also deletes all the other ones. It's too slow to run every frame or anything like that.

this may be a better question for #networks

[rapid barn]

Oh

Ok

[dawn quiver]

do u guys really think python can make good games?

[desert umbra]

It can actually do quite alot

Because most of the game libraries in python are written in C/C++ so those languages take care of all of the rendering, animations, etc

And those libraries just have a python API for using their lower level stuff

So In most game libraries C/C++ do almost all the work and python is just for ease of use withthe C api

[dawn quiver]

Hey Thanks for replying but how can i calcuate the speed when a collision occurs?

For now i am using pythagoras theorem to give velocity to the particle when collision happens But the behaviour of collision does not seems correct.

[raven marsh]

hello there, so i use pygame for dis, ok why when i not moving mouse or not press any button the screen freeze? (code later)

[frank field]

Hey @raven marsh!

You either uploaded a .txt file or entered a message that was too long. Please use our paste bin instead.

[raven marsh]

bruh ok

https://paste.pythondiscord.com/tuqohucofe there code

[sinful lodge]

huh

[proper peak]

Indeed it doesn't. You need to decompose the velocity vector into two components - the radial one (along the line from the center to the collision point) and the tangential one (perpendicular to the first one). The first component's sign gets flipped, the second component is unchanged.

decomposing a vector like that, can be done by scalar-multiplying it by a unit vector in the right direction. So start by obtaining two unit (length of 1) vectors, one along the line from the center to the collision point and another perpendicular to that

[dawn quiver]

i don't know how to get the angle theta

[proper peak]

You shouldn't need any angles with this approach

only the center of the circle, the collision point, and the velocity vector of the projectile

[dawn quiver]

can u please give a direct formula to obtain new velocity?

[dawn quiver]

This explanation seems complex

[proper peak]

Well, something along the lines of

radial_vector = (collision_point - circle_center).normalize()
new_velocity = -2*radial_vector * velocity.dot(radial_vector)

the idea is to subtract twice the radial component of the velocity (which is the same as flipping the sign of that component while leaving the tangential one unchanged)

[dawn quiver]

I think i have a easier idea compared to this

just using simple circle formulas

But i respect your Answer too and thanks a lot for help dude

How about if i just find theta using this formula

and find the velocity

They aren't working perfectly that's why i asked for help

but i believe i am the one who is causing mistakes in executing them

how to i add tree like object this is pic

just tree

i need chopabble tree

Do you have like a framework that includes objects? Otherwise make a surface and use blit()

[dawn quiver]

idk

[dawn quiver]

.

i want to make survival game

[hot willow]

Just getting a tree on screen is simple, but making it fully Choppable is complex

[dawn quiver]

mhm

[hot willow]

If you want to get started by putting it on screen, first make a rect. Do this by using:

tree_rect = pygame.rect.Rect(<x>, <y>, <width>, <height>)

This will make the Collision. Make sure to replace x and y with your position, and width and height with your size

Don't use the <> either

[dawn quiver]

yeah but i don't know how to install pygame

Ok well thats step one

@neon plume are you making game?

[proper peak]

I just wouldn't use pygame.Vector2 for this if it's annoying like this.

something like a namedtuple would do:

class IVec2(typing.NamedTuple):
    x: int
    y: int
MAP_SIZE = IVec2(20, 15)

This wouldn't have vector operations, but if you need them, you can always convert it to a pygame vector

An alternative which has vectorized operations (but doesn't have field access like .x) would be a numpy array.

No real way around it I'm afraid. It wouldn't be 70 lines though. Actually, I think I have an old implementation somewhere...]

@dataclass
class Point:
    x: int
    y: int

    def __add__(self, other: "Point"):
        assert isinstance(other, Point)
        return Point(x=self.x + other.x, y=self.y + other.y)

    def __sub__(self, other: "Point"):
        assert isinstance(other, Point)
        return Point(x=self.x - other.x, y=self.y - other.y)

    def __mul__(self, other: int):
        assert isinstance(other, int)
        return Point(x=self.x * other, y=self.y * other)

    def __iter__(self):
        yield self.x
        yield self.y

    def __getitem__(self, item):
        return (self.x, self.y)[item]

    def toarray(self) -> np.ndarray:
        return np.array([self.x, self.y])

this one, say

rename it to IVec2 or something like that and there you go

could have saved some methods if it was a NamedTuple, actually

class IVec2(NamedTuple):
    x: int
    y: int

    def __add__(self, other: "IVec2") -> "IVec2":
        assert isinstance(other, IVec2)
        return IVec2(x=self.x + other.x, y=self.y + other.y)

    def __sub__(self, other: "IVec2") -> "IVec2":
        assert isinstance(other, IVec2)
        return IVec2(x=self.x - other.x, y=self.y - other.y)

    def __mul__(self, other: int) -> "IVec2":
        assert isinstance(other, int)
        return IVec2(x=self.x * other, y=self.y * other)

    def __rmul__(self, other: int) -> "IVec2":
        assert isinstance(other, int)
        return IVec2(x=self.x * other, y=self.y * other)

    def toarray(self) -> np.ndarray:
        return np.array([self.x, self.y])

yeah, that's shorter

What do you mean? Type hints in general, or ones with "string" types?

Yeah, I need to do this here because IVec2 isn't declared yet when the methods are declared

so I need this to not get a nameerror. Type checkers understand what I meant here.

also I forgot return types...

there, fixed.

yes, it works because it's iterable.

any iterable can be unpacked

(And it's iterable because namedtuples automatically are. Compare to the old Point where I had to do __iter__ manually)

Not really possible, they are internally very different. Also, doesn't really make sense: this vector is only for ints after all, whereas pygame's is for floats.

Making it a namedtuple gives you __iter__ and __getitem__ for free:

v = IVec2(5, 10)
# iteration:
for el in v:
    print(el) # 5\n10
# iterable unpacking:
x, y = v
# indexing:
print(v[0]) # 5

compare to my Point, which is only a dataclass, where I had to implement both of them manually:

    def __iter__(self):
        yield self.x
        yield self.y

    def __getitem__(self, item):
        return (self.x, self.y)[item]

Ehh, sorta
Layer 1) Of course they are the same - it's not like @dataclass and NamedTuple are some sort of magic; they just save time on writing boilerplate compared to just classes.
Layer 2) Actually this is a lie and NamedTuple is a little bit magic. Because it also changes the class's representation in memory to be stored roughly like a tuple, which is lighter than a normal object. The docs mention it:

Named tuple instances do not have per-instance dictionaries, so they are lightweight and require no more memory than regular tuples.

yeah, pretty much

[charred quail]

whats the most effiecent way to save all game data to a file

[potent ice]

Depend what you are saving

[charred quail]

im not using any library specifically i just said it in the game dev channel cuz ik game devs use some way to store all data to a file, im not using this for a game even

[potent ice]

If you are saving some simple data you can just write a json file for example?

[charred quail]

but like what if u have like a whole game, with a buncha classes like the player and the enemies or smthng and the world data and all, how would u save all of those for the next launch

[potent ice]

You'd just have to take that into account when designing the game.

Your game will have to support loading and saving certain states.

[charred quail]

yeah but how would u save all of the game data to a file at once and easily

[potent ice]

You just store the internal game states. As little information as possible.

For example the player position and various stats + other states related to the map or area the player is located?

If it's a lot of data you might need to design some more compact file format

[normal anvil]

hey guys

i need a game developer in my team im already working on

the code needs to be in python

or better

[quaint fog]

whats better arcade or pygame

[dawn quiver]

Honestly.. I'm surprised someone hasn't already linked it but there is a comparison page on the arcade website

It's pretty biased, they say PyGame doesn't support scaling or rotation, but it does! 😄
And also the "default hitbox" comparison makes it look back, but pygame.Surface.get_bounding_rect exists, and you can even do pixel perfect collision using pygame.mask.Mask.overlap

But anyways I wouldn't say either is "better" or "worse" than the other, it's up to your preference :)
Arcade enforces an object oriented paradigm, which can be a pro if you were going to use it anyways, but if not pygame is pretty flexible on the paradigm side

I might also be a bit biased, since I've contributed to the PyGame repository whereas I haven't to arcade's

They both use different frameworks and are also slightly different from each other, pygame is more of a wrapper for SDL with added functionality, whereas Arcade was made more with 2d game dev on its mind
Of course pygame was as well, but you get more from arcade right off the bat

But there are a lot of support libraries which you can use along with pygame, such as pygame_gui and pymunk which are really nice. I'm not too sure about arcade, but they probably wouldn't need them considering a lot comes with the installation

[plush edge]

ok thx for the idea

[latent stone]

If you're familiar with ideas about force and acceleration, you can calculate the force between the objects with some equation like force = k/distance where k is some constant. This will give a higher force as the distance decreases.

You can calculate the direction of the force using the coordinates of the rectangle and the mouse, perhaps using a function like math.dist.

[sinful lodge]

really neat! however dont you find the animations and particles a little too fasy

fast

maybe make them slower?

[dawn quiver]

Hm... the bezier curves movement might be a tad bit fast yeah

Good idea, I'll slow it down a bit 👍

Yeah probably

[old hill]

Thank you so much for your idea!
I can finally push the rectangle with the mouse around.😄 It still fells a bit weird but it works for now.
I gave the rectangle a mass and calculated the acceleration with the force and the mass.

[latent stone]

Np! If it feels weird you can probably tweak the equation to have the distance raised to some power, e.g. make it inverse square instead of just inverse

Would probably be better to ask in a help channel

[devout nexus]

oh true sry

[potent ice]

Recruitment here is against the rules

[tawny pumice]

Ohhh I’m Sorry

[potent ice]

Anything open source is fine usually, but when money is involved that's crossing the line.

[white nova]

hi guys

im new here

[gentle ivy]

I've asked this question some time ago in #python on Libera, and now I'm relaying it here.
Does anyone have an example PyGame program that has a game map of a specific size, and when the player moves (via i.e. WASD), the player is centered and the surroundings move around the player at the perspective of the viewport?

[slate wharf]

what on earth do you mean by this

do you mean like

the player is on the center of the screen and when the player moves

[unreal river]

like a camera?

[slate wharf]

the world moves around the player technically

[slate wharf]

i think that they mean that the player will be always centered in the middle of the screen so when you move the world technically moves around you

[slate wharf]

if thats what you mean then yes i do have plenty of examples, but not in pygame

i could easily make one in pygame if you so desire

[unreal river]

that's what I mean

[slate wharf]

ah

[unreal river]

the camera is focused on the player

[gentle ivy]

That is probably what I intended, though I don't work with cameras and I'm unfamiliar with the terminology

[lapis ore]

Hey can anyone suggest my some basic games for python.

[unreal river]

pong, space invaders, etc.

[drowsy trellis]

can anyone tell me how to avoid shadowing of parameters ?

[unreal river]

try not naming it the same as another variable name that already exists (Only do if you want it to be the same)

Note that this is not the appropriate channel for your question

[raven marsh]

hello, i'm using ursina engine, and i got dis problem, i wanna make a cube with custom texture (texture is the grass.png) but it turns out that the output is kinda...... yeh, how to fix that? ty

[tranquil girder]

That's kind of an inefficient layout, but what you should do is make a custom 3d model with custom uvs. See this: https://www.youtube.com/watch?v=Yx2JNbv8Kpg&t=19s&ab_channel=FlippedNormalsMarketplace

[sudden ridge]

#discord-bots

[raven marsh]

gotchu ty

[turbid fog]

Why is this happening>

[potent ice]

What should be happening instead?

[dim vale]

3d games in python, is there any good imports or do i just have to make raytracing through pygame

[grand imp]

don't do raytracing through pygame or SDL unless you're after learning about raytracers instead of a performant game

Ursina is a popular choice for 3d in Python

[dim vale]

ok ty

[grand imp]

There's also Panda3D

I think one is based on the other, but I forget which is which

[potent ice]

Ursina is a higher level wrapper over Panda3D

[icy loom]

main.py in system32? noice

or it's on PATH, even worse

[brisk dawn]

any realistic jump physics for pygame?

[hot willow]

Which would you recommend for an experienced pygame user looking to switch to 3d?

[rugged herald]

I got a question, I have a final project in comp sci in vs code. I'm just wondering, if I were to code let's say pokemon. Using a database and csv file, just the og 151. Set each pokemon 4 set moves at level 100 stats and just let the user pick 2 and fight. Would it generally be somewhat easy. I feel like I'm gonna do this but I'm just wondering if anyone has tips or tricks to some of this stuff

I wish I could use pygame

I'm not allowed to install any other programs other then flask and that's not really useful unless I wanna do bootstrap and make a website

[dawn quiver]

He probably expected a full functioning production ready game running instead of that

[dawn quiver]

Ok, me being the big noob around here which one should I go with?

If i use ursina can I also use panda3d with it?

[potent ice]

I'd just start playing around with Ursina if you want a nicer abstraction.

[dawn quiver]

Yes but since ursina is a wrapper of panda3d

Can i still use panda3d with it?

[potent ice]

I don't see why not. It's an open source library you can build on if needed.

[dawn quiver]

I see great!

So I will use ursina abstraction and panda3d exclusive features

Time to check it

It does lack an editor but this is not a big problem

[tranquil girder]

yes, you can

[dawn quiver]

yes

[tranquil girder]

there's a level editor in the works, but you can also use blender as a level editor

or make your own, which is kinda fun

[dawn quiver]

Hmm

[dawn quiver]

What is the status of vulkan renderer?

@potent ice

[potent ice]

pokepetter would know 😄

[tranquil girder]

More like rdb would know. You don't need a vulkan renderer though

[dawn quiver]

[dawn quiver]

Just asking to know my limits

[normal silo]

IIRC it's still WIP, but seems like there is a good amount of effort being put into it / progress because it's widely requested.

[dawn quiver]

Yeaa

I came from C++ background

I want to give python a go

[normal silo]

Panda3D does both (it has a bindings generator in it (so it can do more than Python, I think someone recently requested Nim)).

Python is very nice if you don't really want to deal with project setup and just go.

(For these kinds of quick projects Ursina helps too)

(*More like non-projects)

[dawn quiver]

It would be nice if I got a game up and running fast!

Maybe i might even use it to visualize some stuff

[normal silo]

I use Ursina/Panda3D for data visualization (and I don't think i'm the only one doing that).

[dawn quiver]

Ohh

Ok im motivated

[normal silo]

*Yeah there is at least one other ML engineer that has shared that they are using Ursina for data vis.

[frozen knoll]

Arcade 2.6.14 is out:

https://api.arcade.academy/en/latest/development/release_notes.html

[dawn quiver]

You have better documentation than ursina

[frozen knoll]

We try really hard to make the documentation easy and usable, thanks for the kind words.

[potent ice]

Help making the docs better? 🙂

[proud egret]

has anyone made a game in a notebook?

[ripe hornet]

Hey guys! Can I programe a nice simple game with python? If yes, what library or module do you suggest me to use?

[potent ice]

What kind of game?

[ripe hornet]

I dont have an idea yet

I just think it would be fun and relaxing to make one]

[potent ice]

Maybe just start with arcade then : https://api.arcade.academy/en/latest/

[ripe hornet]

@potent ice do you have any idea?

[potent ice]

Check tutorials and examples to get some ideas

[ripe hornet]

Idk what python is capable of when it comes to games..

[dawn quiver]

Well if it's just a nice simple game, especially if 2d, you shouldnt run into any Python faulty problems

Someone has made an entire terraria clone with Python, using a wrapper for SDL (pygame)

[slender lark]

hey

[potent ice]

Start with something very simple initially 😉

[white vector]

Beginning with game development i would say terminal games first then build up to gui.
After all, that's the order on which humanity figured it out, right?

[unreal river]

ye

[austere estuary]

Is it against server rules to ask for help debugging this presumably simple collision problem I'm having? I thought a case of beer would help but I think it made matters worse

I could google it but the alcohol has made me feel social

[white vector]

Although my first terminal game in python almost looks like a gui.

[tame patio]

I tried pygame but I didn't like it, so I was thinking of moving to a new lib and tbh I really liked Arcade. Keep up the great work 😃

[dawn quiver]

You can use unity for creating grapics right for pygames? :3

Hey @keen phoenix!

It looks like you tried to attach a Python file - please use a code-pasting service such as https://paste.pythondiscord.com

[keen phoenix]

Ok, so I have crated a little raycaster and it has a very small, but also very bad problem. So I'm trying to render textures on walls, the problem is when a wall is near the camera, it renders fine (picture 1), but when a wall is far away from the camera, it renders in very low quality (picture 2). I know why this happens, the walls have a fixed x scale and when the textures render on far away objects they appear low quality. But I don't know the solution to this. Here's my code: https://paste.pythondiscord.com/awihewiziz. The problem appears in the full_raycast function. Ignore the ppm_loader module, it just loads a .ppm file into a 2D list.

[keen phoenix]

I am making a Wolfenstein 3d clone so textures are neccesary

[torn jackal]

hey guys, I just would like to put a file which is string in integer, there is just a simple number is the file (0) but it showsme this error : python ValueError: invalid literal for int() with base 10: ''

please help

and mention me if u can help

okay forget it works now 🙂

[grim abyss]

Maybe this can help you. I would guess your scaling the texture wrong... https://killerrobotics.me/2021/08/13/raycasting-game-in-python-and-pygame-part-1/comment-page-1/

[keen phoenix]

Ooh

It looks like I have done it correctly

But I have used a slow ray algorithm so setting the number of rays to 480 would be impossible

Now I'm trying to understand the DDA algorithm

Thank you very much!

[grim abyss]

Sure

[noble sundial]

On a 2d game, with a set of destinations, have a set (different number) of enemies to move to a destination. Each enemy should go to the closests and two enemies should not go on the same destination.

[grim abyss]

anybody know a decent site where I can get high-quality sprites/textures? I wanna mess around with arcade

[regal burrow]

hey i have a question? im making a tool for fallout four special chart that will optimize to what class you want to play but i dont know wether to send it in this channel or #tools-and-devops

[true trail]

class Char(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.counter = 0

        char_1 = pygame.image.load('assets/character/char1.png').convert_alpha()
        char_2 = pygame.image.load('assets/character/char2.png').convert_alpha()
        char_right = pygame.image.load('assets/character/char_right.png').convert_alpha()
        char_left = pygame.image.load('assets/character/char_left.png').convert_alpha()

        self.char_side = [char_1, char_2, char_right, char_left]
        self.char_index = 0

        self.image = pygame.transform.scale(self.char_side[self.char_index], (80, 80))
        self.rect = self.image.get_rect(center = (width/2, height/2))

        self.imageh = test_font.render(f'{self.counter}', False, (0,0,0))
        self.recth = self.imageh.get_rect(topleft = (730,32))

    def movement(self):
        keys = pygame.key.get_pressed()

        if keys[pygame.K_DOWN] and self.rect.bottom < height - 10:
            self.image = pygame.transform.scale(self.char_side[0], (80, 80))
            self.rect.move_ip(0, 5)

        if keys[pygame.K_UP] and self.rect.top > 10:
            self.image = pygame.transform.scale(self.char_side[1], (80, 80))
            self.rect.move_ip(0, -5)

        if keys[pygame.K_RIGHT] and self.rect.right < width - 10:
            self.image = pygame.transform.scale(self.char_side[2], (80, 80))
            self.rect.move_ip(5, 0)

        if keys[pygame.K_LEFT] and self.rect.left > 10:
            self.image = pygame.transform.scale(self.char_side[3], (80, 80))
            self.rect.move_ip(-5, 0)

    def counting(self):
        for i in money:
            if self.rect.colliderect(i):
                self.counter += 0.1
                print(self.counter)

    def drawing(self):
        screen.blit(self.imageh, self.recth)

    def update(self):
        self.movement()
        self.counting()
        self.drawing()

[grim abyss]

i would say here.

[true trail]

can someone tell me the reason why self.drawing doesnt work?

i mean if i wanna print self.counter, it increase the value

[grim abyss]

screen.blit(self.imageh.....) imageh?

[true trail]

but in the window it doesnt screen the current value

[true trail]

yes

i have one self.image and one self.imageh

is it possible to do?

[true trail]

?

[grim abyss]

idk dude. I'm using arcade atm. pygame is.......old, lol

[true trail]

what is it?

[grim abyss]

!pypi arcade

[frank field]

arcade v2.6.14

Arcade Game Development Library

[true trail]

pyagme @_@

too sad

[keen phoenix]

cc0textures.com

for high res

[dawn quiver]

What

You want to draw self.counter on the window?

Make a font object as a class variable,

self.font = pygame.font.Font(None, 15)

None loads the default font, 15 is the size, you can change that to whatever you want

And then to draw it

text_surf = self.font.render(str(self.counter), True, "white")
screen.blit(text_surf, pos)

[dawn quiver]

Well, screen doesn't seem to be defined

[true trail]

i didnt send full code but there is!

[dawn quiver]

Yeah, but not in that scope

Did you get any errors?

[true trail]

no

[dawn quiver]

Are you calling update?

[true trail]

yes

[dawn quiver]

Are you sureee

[true trail]

but i still didnt try that

[dawn quiver]

I didn't completely understand the problem

Did you want the counter to appear on the screen?

[true trail]

can i write to u in pvt?

[dawn quiver]

No

I don't use DMs

We can continue here

[true trail]

btw yes, self. counter in the counting function works, i mean, everytime increase correctely

[dawn quiver]

So you do want a counter to appear on the screen? That's the problem correct?

[true trail]

but the self.counter in the self.imageh, doesnt work, i mean, display "0" but then doesnt increase when i touch "i* in money

[dawn quiver]

You can do this then

[dawn quiver]

Oh I see a test_font.render now, yeah you have to re-render it every frame
Do it like this

    def drawing(self):
        self.imageh = test_font.render(f'{self.counter}', False, (0,0,0))
        screen.blit(self.imageh, self.recth) 

Try this and let me know

[true trail]

but this i have to add in the class?

[dawn quiver]

Just modify your existing method

[true trail]

ok, i will try in 20-25 mins because im not on the PC, but I'll go soon as i possible

thanks

[true trail]

i think i love u

really, its from my heart

[dawn quiver]

Did it work?

[true trail]

yes

[true trail]

it works perfectly

[dawn quiver]

Great!

[true trail]

i have a question, is there a way to use that "self.counter" in another class?

[true trail]

this is my game, and for example i would like to add a cave that costs 1.50, and ofc i have to decrease that number, can i do from another class?

[true trail]

@dawn quiver is it possible?

[gentle ivy]

I need an example in PyGame where player movement is keyboard-controlled and the player is centered (i.e. other objects move around the player). As I am very rarely on here, please highlight me if you kindly reply. Thanks!

[brittle venture]

Can a 16 gb ram without graphic card for a laptop can game be developed on it ?

To get more more battery life

[grim abyss]

terrible sentence structure. what does this sentence mean?

are you asking if you can develop a game on a laptop with an integrated gpu that has 16GB of ram?

if so, why yes of course...

[brittle venture]

Yes

[tame patio]

Yeah

[mystic parcel]

i want to learn pygame but is it possible on a 4 gig ram laptop?

like a very low spec laptop

[dawn quiver]

I had a 4 GB Ram laptop previously, it is completely possible.

[mystic parcel]

i dont know what gen this is but its really old

like very old

now can i ask again, is it really possible?

[mortal yew]

I actually wrote a project using PyCharm and PyGame with 4GB of RAM.
Specs: 1.8 GHz CPU, 4 GB RAM, 2 cores.

You're probably fine if you use an editor like IDLE.

[mystic parcel]

ah thanks

i was doubting my laptop but this helped

[true trail]

@dawn quiver ?

[dawn quiver]

Hello

[true trail]

can i ask another thing to u?

[dawn quiver]

Of course, you would need to pass in the counter value from outside to wherever it is required, take this example

class Foo:
    def __init__(self):
        self.counter = 0

    def update(self): 
        pass

class Cave:
    def update(self, counter: float):
        pass

foo = Foo()
cave = Cave()
while True:
    foo.update()
    cave.update(foo.counter)

[true trail]

but foo and cave are class or def?

[true trail]

.

[dawn quiver]

Sorry, my bad, I made a typo

[true trail]

class Char(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        self.counter = 0
        char_1 = pygame.image.load('assets/character/char1.png').convert_alpha()
        char_2 = pygame.image.load('assets/character/char2.png').convert_alpha()
        char_right = pygame.image.load('assets/character/char_right.png').convert_alpha()
        char_left = pygame.image.load('assets/character/char_left.png').convert_alpha()

        self.char_side = [char_1, char_2, char_right, char_left]
        self.char_index = 0

        self.image = pygame.transform.scale(self.char_side[self.char_index], (80, 80))
        self.rect = self.image.get_rect(center = (width/2, height/2))
    
        self.imageh = test_font.render(f'{self.counter}', False, (0,0,0))
        self.recth = self.imageh.get_rect(topleft = (730,32))

    def movement(self):
          ....

    def counting(self):
        for i in money:
            if self.rect.colliderect(i):
                self.counter += 0.1
                #print(self.counter)

    def drawing(self):
        self.imageh = test_font.render(f'{format(self.counter, ".2f")}', False, (255,255,255))
        screen.blit(self.imageh, self.recth) 

    def update(self):
        self.movement()
        self.counting()
        self.drawing()

but i want to pass the self.counter that has a value, becuase self.counter is always 0

[true trail]

then increse but in this way, which self.counter will give me?

[dawn quiver]

It isnt

[dawn quiver]

It increases as shown here

[true trail]

ok so i have to create something like this

class Cave(pygame.sprite.Sprite):
  def __init__(self):
    super().__init__()
    self image = ...
    
    self.rect = ...
  
  then how can i use the current counter of Char()

[dawn quiver]

Yes?

What?

[true trail]

i dont understand how can i use the self.counter of char, for example here, wait

[dawn quiver]

You pass into the update method which you have to create

[true trail]

@dawn quiver in this way?

[dawn quiver]

Yes, you can now use the counter as you wanted.

[true trail]

what? how xD

[dawn quiver]

I showed you an example.

You just need to map the Foo and Cave I showed to what you have.

[dawn quiver]

Yes

[true trail]

its white and it doesnt work

[dawn quiver]

You arent doing anything with it

What do you mean by "white"

That's just the syntax highlighting for attributes.

[dawn quiver]

You need to use it to make it work

[true trail]

yeah, but here i'm using

[dawn quiver]

What?

You arent

Hover over counter

[true trail]

i wanna print in someway the current counter in the def is_collided_with(self)

[dawn quiver]

You should pass it into is_collided_with after creating a parameter for it, instead of using the variable from the global scope like that..

[dawn quiver]

Well you kill the sprite, so how about printing first

I dont use sprite groups

[gentle ivy]

It works on a Core 2 Duo with one gigabyte of RAM.

[true trail]

mhh

[gentle ivy]

My OS's overhead is about 280 MiB, leaving me about 700 MiB of usable RAM for PyGame 🙂

[true trail]

so it cant work how i'm doing i guess

[dawn quiver]

It probably could, but I'm not sure if that kill method ends the outer method, probably not

[true trail]

i think i'm making mistakes lol

[dawn quiver]

It's fine, everyone makes mistakes

[true trail]

yes, the problem is that i have no ideas

[true trail]

sry but just a thing, using sprites, if i wanna print the counter in the class Money, how can i do?

[ancient tendon]

does game development include app here

cuz i want to tell abt my app

[true trail]

twitter?

[grim abyss]

@dawn quiver https://pythonhosted.org/planar/vectors.html planar is useful though not maintained anymore. It also has line-segments

Maybe I did, lol. I thought you had asked about creating a vector class....

[dawn quiver]

Nope

unity asset store

i solved my issue i just switched over to panda3d

now im just having a issue of screenshotting

[grim abyss]

Was it free?

[broken citrus]

50$

[grim abyss]

wow, lol

[broken citrus]

pretty cheap

u get like 2000 assets

[grim abyss]

now you tell me, lol

[broken citrus]

animations

human models

weapons

and scripts

Hi I’m making a small mr wolf game using python matplotlib for my course the assessment is due Sunday and I can’t get the code to do what I want I was wondering if I could get on a call with someone so that I can get some help ?

[ancient tendon]

do u guys use pytqt5

frequently

for app dev

[hot mesa]

@tame vale can u help me?

[tame vale]

Yup

[broken citrus]

how do light up the whole scene?

in panda3d

[potent ice]

There is an Ursina and Panda3D discord as well

[broken citrus]

no way where

[potent ice]

Their project web pages (and probably docs) link to it

That's why you should read docs 🙂

[broken citrus]

I do

i dont usually look for socials in docs

i just come here and ask about it

and if there is no answer i dive into the source code

[potent ice]

https://www.panda3d.org/contact/

[broken citrus]

yea i just joined it

[potent ice]

Discord link Ursina https://www.ursinaengine.org/

[broken citrus]

i dont use ursina but should i?

[potent ice]

Why not. So much overlap anyway

[broken citrus]

whats ur opinion on both

panda3d gets tidious fast and doesn't look good

[potent ice]

Then use ursina

[broken citrus]

ok for sure

[vagrant saddle]

what do you mean by doesn't look good ?

[vagrant saddle]

looks like the default pipeline which is nice enough to run on almost all desktop / mobile device without expensive gpu

[vagrant saddle]

if you change pipeline you can get stuff like https://www.youtube.com/user/tostbrot21/videos

oh yea this guy tobspr
