Watching videos is not enough

Watching videos is where I discover a lot, but learning it is all hands on keyboard

[drifting yew]

not sure if I want to use pygame event for anything other than mouse and button input, seems too complicated

[limber veldt]

That's pretty much all I use it for, when I need a timer, I usually use a Timer() class or just accumulate dt in a variable

[glass light]

It's not complicated but it does make things harder to follow. Depends on your needs. Firing off events is a great way to reduce decoupling between objects

[drifting yew]

I need to have a turn-based system with time units, and once the value of a unit has counted down to 0 it's their turn

[pine smelt]

a timer's probably the better way to handle that

and just makes more sense in general

[pine smelt]

what does decoupling mean

[glass light]

It means making stuff not depend on stuff

basically 😄

Real-life example is in my game (small plug: https://store.steampowered.com/app/3122220/Mr_Figs)

there are pressure plates.
Originally I had a pressure plate class and I'd inject the "spike" class of the spike it triggered into the constructor of the pressure plate

Now I do don't do any of that. Now, it takes a list of id's of sprites to toggle.

It's still coupled slightly but less so

[untold sigil]

The issue with blitting the enemy is that you're passing enemy_list directly into screen.blit(), but screen.blit() requires a specific Rect position, not a list. You should iterate over enemy_list to get each enemy's Rect and blit it individually. Try this inside your game loop-

for enemy_rect in enemy_list:
    screen.blit(enemy, enemy_rect)

This will maek sure that each enemy is blitted at its respective position.

[dawn quiver]

Hi

Which type of game are you talking about?

[drifting yew]

did the game require a rewrite for steam?

[glass light]

Nope, why would it?

[limber veldt]

Most games on steam aren't released as python/pygame source code. I see this game isn't yet released but still, the question is, in what form will the release be?

[glass light]

Ah I see what you mean.
For windows it'll be frozen as an .exe and you'll just run that

I'm pretty sure pyinstaller can do the same for Linux too so I'm hoping to bundle a single executable file on Linux rather than a bunch of scripts.

To be honest I haven't looked into it fully but I'm not too keen on just having the source fully available once purchased

[stuck cliff]

hey guys, i am having some proplems with some microbit code, i have tried so many things to try and get this to work but nothing is working, this should be such a simple thing. if you guys can help at all please do, this is for a assesment where i am making space invaders on a micro bit but the most basic movent isnt working (dont mind the uncalled variables they will be used later) heres my code (from microbit import *
from random import *

screenreset = 2
flyerposition = 2
flyerhealth = 5
reset = 0
display.set_pixel(flyerposition, 4, 9) # set dot in middle
while True: # start game loop
screenreset = flyerposition # set screenreset to red dot last position
if button_a.is_pressed():
sleep(200) # debounce button
flyerposition -= 1 # set new position for dot 1 pixel left
if flyerposition < 0: # make sure it doesnt overshoot
flyerposition = 0
display.set_pixel(screenreset, 4, 0)
display.set_pixel(flyerposition, 4, 9)
if button_b.is_pressed():
sleep(200) # debounce button
flyerposition += 1 # set new position for dot 1 pixel right
if flyerposition > 4: # make sure it doesnt overshoot
flyerposition = 4
display.set_pixel(screenreset, 4, 0)
display.set_pixel(flyerposition, 4, 9))

ursina v7.0.0

An easy to use game engine/framework for python.

Released on <t:1713733992:D>.

[drifting yew]

idk, does the game have a visible background? if you always set the screen to match where the flyer is it could look like no movement.

or maybe something about the button functions

maybe try printing something as test if a button is pressed to see if that works

[drifting yew]

I'm not exactly sure how I want to treat enemies that are on adjacent dungeon levels. Being able to follow you if you went to another floor while they were right next to you, most likely.

but also moving around and maybe even changing floors sometimes while not directly next to player

[finite crow]

Hey guys I made this over a year ago, well I started the project. But i was wondering what you guys thought of the idea? https://github.com/plunder707/Aithera

Hi everyone! I did my 3D engine with Pygame, made the movement but when I tried to do the camera rotation like in a first-person game, it did like in a third-person game and I can't figure out how to fix it.

I would be very happy if someone would help me as fast as possible.

My code: https://paste.pythondiscord.com/NCFA

[finite crow]

It seems like the camera is roating around the objects instead of the FPS perspective you want. Try this

    # Сдвиг точки относительно позиции камеры (центрирование объектов вокруг камеры)
    x -= camera_position[0]
    y -= camera_position[1]
    z -= camera_position[2]

    # Применяем поворот камеры (yaw и pitch) ко всем объектам
    cos_yaw = math.cos(math.radians(yaw))
    sin_yaw = math.sin(math.radians(yaw))
    cos_pitch = math.cos(math.radians(pitch))
    sin_pitch = math.sin(math.radians(pitch))

    # Вращение объектов вокруг оси X (pitch) - обратите внимание на порядок!
    rotatedY = y * cos_pitch - z * sin_pitch 
    rotatedZ = y * sin_pitch + z * cos_pitch

    # Вращение объектов вокруг оси Y (yaw)
    rotatedX = x * cos_yaw + rotatedZ * sin_yaw  # Изменено: + вместо -
    rotatedZ = -x * sin_yaw + rotatedZ * cos_yaw # Изменено: - вместо + и порядок переменных

    # Проецирование точки на экран
    xscreen = int(rotatedX * (fov / (fov + rotatedZ + 1)) + centerX)
    yscreen = int(rotatedY * (fov / (fov + rotatedZ + 1)) + centerY)

    return (xscreen, yscreen)```

[finite crow]

Also I know Russian, its cool. But Slave Ukraine.

[pure flint]

It's the same problem, but now the objects can rotate around me also on the Y axis

Try this. I ran it seems to work. Is that what you're looking for? https://paste.pythondiscord.com/2SRA

[finite crow]

Try this

[spice tartan]

use code bar ```

[pure flint]

you can clearly see that it's still a third-person view

And it seems like you are chatGPT generating it, I tryied soo but chatGPT made the same mistake

so yeah, don't generate the code

[spice tartan]

honestly it looks funny

try ask in #1035199133436354600

I'd like to see the answer too

[finite crow]

The generated code i pasted doesnt do that.

I'm not sure what you're doing, but I didnt get that exxpereince you're seeing in the video.

Maybe the issue is something else.

[pure flint]

can you record a video of your expirience?

[pure flint]

I tryied, 4 times, no one answered and it's annoying to recreate the post every hour

[vagrant saddle]

are you rotating the camera at 0,0,0 and then translate it to its pos ?

[finite crow]

Try this, it seems to work better but its hard to test because of my juypter env i think. ```def create_point(x, y, z):
# Shift the point relative to the camera position
x -= camera_position[0]
y -= camera_position[1]
z -= camera_position[2]

# Apply inverse camera rotation (use negative angles)
cos_yaw = math.cos(math.radians(-yaw))
sin_yaw = math.sin(math.radians(-yaw)) 
cos_pitch = math.cos(math.radians(-pitch))
sin_pitch = math.sin(math.radians(-pitch))

# Rotate around Y-axis (yaw)
rotatedX = x * cos_yaw - z * sin_yaw
rotatedZ = x * sin_yaw + z * cos_yaw

# Rotate around X-axis (pitch)  
rotatedY = y * cos_pitch - rotatedZ * sin_pitch
rotatedZ = y * sin_pitch + rotatedZ * cos_pitch

# Project the 3D point to 2D screen space
if rotatedZ != 0:
    xscreen = int(rotatedX * (fov / (fov + rotatedZ)) + centerX)
    yscreen = int(rotatedY * (fov / (fov + rotatedZ)) + centerY)
else: 
    xscreen, yscreen = centerX, centerY # Handle division by zero

return (xscreen, yscreen)```

[pure flint]

nah it's the same

[finite crow]

Im sorry i guess i'd help if I could could move the camera and FPS view around. Its all over the place

[pure flint]

I think yeah

[spice tartan]

might want to pop in main chat and notify some people

[pure flint]

how do I know who to mention

[pure flint]

@vagrant saddle

[spice tartan]

just say something like "can anyone help me on #"

it works sometimes for me

[spice tartan]

have u said collision on the camera and the floor?

i think it just literally goes thru the floor i think

[pure flint]

that's not the problem

[spice tartan]

maybe try anchor it.. like locking it in one fixed place.. idk what to say

[pure flint]

I can't figure out how

[spice tartan]

the thing is that you're doing it raw

so uh idk

if ur using like unity or godot it should have options for it

[slate sentinel]

Hi all. I recently developed a 2D roguelike(very early stages but playable) using pygame in python along with custom music. Now I am not sure how to make it online so others can play and review on it. Can anyone guide me through the process or link me to a place I can study about it? Thank you.

I structured the code in pycharm IDE.

[pine smelt]

are you in thr pygame discord

the pygame-web channel and pmp-p will be a great help

[drifting yew]

I too am working on a roguelike (absolutely unplayable lol)

[finite crow]

I wanted t o make a game that uses https://gitlab.com/2009scape The runscape sorce code, but I wanted to implement my AI idea in the mechanics.

https://github.com/plunder707/Aithera

[fleet talon]

how to run this?

[finite crow]

Sorry, it was a private repo. its still under construction, but I'd like to get the project rolling. I was starting to flesh out the files. But its a big job.

[glass light]

Worked on some gelatinous blob hazards today

Didn't get loads done today however. Working on a new trailer and it's sucking precisely 100% of my free time

[past sandal]

looks awesome

[limber veldt]

I've just been refactoring again. I had all behavior of picking up and moving pieces in main, including that for both human and ai players, with conditions for switching between them. Have now moved all that behavior into a NewPlayer() class having generic player behaviors which I subclass for HumanPlayer() and AIPlayer() with each of those having specific piece handling behaviors. I think it makes more sense now, at least to me

So now in main, I just have a callback from each of the players (human and AI) to trigger the player change, then call the next player to play()

Main just does some bookkeeping, like adding the move to the move list, so got rid of a lot of code there, which was kinda the goal

Checks for game over and stuff

[limber veldt]

The artwork is awesome too, is the movement grid based?

[glass light]

It is grid based but still kind of smooth. You can hold a key down for example and you'll just keep travelling until you release, at which point you'll be taken to the nearest tile.

Hoping it doesn't put people off as I know it's not super common

[drifting yew]

it's like old pokemon works, seems fine

[glass light]

Yeah that and bomberman were my gotos for inspiration on that front

[glass light]

Speaking of the trailer, I just finished it. Simple but gets the point across I reckon
https://www.youtube.com/watch?v=ok3-NbCYyW0

[limber veldt]

No man, seems fine and kinda necessary in a fast action game else it'd be hard af

[tough star]

can someone try my game and see what they think of it? And most importantly report any bugs

https://github.com/spacexplorer11/space_dodge

[glass light]

Sweet that's a relief. Thanks!

[limber veldt]

I'm wondering if it'd be worth the effort to create some sort of command system that oversees a command queue. Like I kind of already have that but not quite like a master queue, each player handles its own behavior and sets states of pieces by calling methods to trigger state changes. Like if piece is to move, player calls its get_moved() method with a square to move to, so get_moved() is basically a command but it's not queued

For normal play, human vs bot, totally unnecessary

[thorn knoll]

coded this game on TechSmart with the theme of "world improvement." the idea is that you play as a robot that collects acorns (it looks like a bird) and can swap out at any time with a robot that collects rain. the seed bot can plant acorns, which become small trees, and the water bot can use rainwater to grow said trees. this is a work in progress. what are your thoughts on my work so far?

[hardy magnet]

thats really cool

i really like the idea too

[thorn knoll]

thx

i just finished adding the storage system

the seed bot can now carry only up to 9 acorns at a time

[hardy magnet]

nice!

[thorn knoll]

:D

small trees = 1 pt. per second

big trees = 3 pts. per second

[hardy magnet]

yeah this is a pretty unique idea you could really build on this concept

[thorn knoll]

yeah

this was rly hard to make

[hardy magnet]

its definitely paying off

[thorn knoll]

@hardy magnet

thats the neat part

i actually DIDNT use OOP!

i made the entire thing without using OOP once

[hardy magnet]

nice

im a huge functional programming shill too

learning OOP is good though id look into it eventually

[thorn knoll]

yeah i am

i just started learning about it today

but i dont rly wanna risk breaking my code like i have 239020293 times already sooooooo yeah

[hardy magnet]

thats part of the process sometimes

you could always start a new project for the sake of learning OOP if you want

[thorn knoll]

well ig yeah

when this is finished ill try reworking the code into oop as a separate project

oop is something like this right?

@hardy magnet

[hardy magnet]

Yeah, classes and stuff

[thorn knoll]

yep

Hi, I have tried to look up for a way to organize folders in games, but whatever I tried to find nothing appears is there a general way devs do to organize folders or is it just something you figure yourself?

[pine smelt]

depends on the person but a way I've found pretty intuitive is having in the main directory

-assets folder
-audio folder
-data folder
-scripts folder
-main.py

in the main.py I have the main "game object" that has the update loop and I organise the scripts by having subfolder for a group of similar stuff

so I'd have for example a folder called particles, a folder called entities and sometimes subfolders within that (e.g. having a folders for players, and another for enemies, WITHIN the entities folder)

[unkempt hornet]

Hey y'all, I'm working on this simple RPG videogame where you battle others' animals, and this is what it looks like so far.
What do you think?

[limber veldt]

For my chess, I did...
-Assets folder < contains sounds folder, images (in multiple folders sorted by categories),
-code folder < has all scripts including players.py, pieces.py, groups.py, board.py, main.py...etc
-stockfish folder < contains stockfish.exe
-saved_data < all saved settings (from the Save Settings button)

[pine smelt]

u don't keep ur main.py in the root?

[pine smelt]

looks great so far the ascii art is rly good

[limber veldt]

Not for this project, for some I have

[pine smelt]

I feel like the A's seem a bit squashed but still readable

[limber veldt]

I did try something a little different with this one. Instead of instancing screen and images in main like I normally do, I instance SCREEN, and a few other globals, and load images in game_setup.py then import them where necessary

I like that it gets all the image loading out my way in main

[pine smelt]

i usually do that in the initilisation of my game object

i have a function called cache_sprites that i run before the main loop

well that in itself calls the cache_sprites class method of every object i need to load the sprites of early

maybe like 2 hours to make the text and 2 hours to colour them?

I like your pfp btw lol

[limber veldt]

Basic saves working, level, position and state of the walls

[spring ether]

elo im a bit of a beginner at python + game development in general

here's some random stuff I coded for my text adventure game

[twilit pike]

that's sick dude. i'm a beginner too and i've never thought about putting my class objects into a dictionary before. i'll probably implement that into my own stuff now too

[spring ether]

Mostly using it so I can easily reference the stat for the respective protagonist without having to make a long list of if else statements

[cerulean nimbus]

what is the .rpy extension?

[spring ether]

renpy script file
The game engine has its own language but also uses python

[pine smelt]

have you made the rooms for all of the coloured keys

also suggestion from a game point of view, after u put the key into the lock thing some sort of screen shake might be useful

tho it depends on where ur going with this

[limber veldt]

Yep, missing are the sentries guarding the keyholes in that level though (deactivated them for testing)

You're not supposed to be able to walk right up and drop the key through the wall, so the sentries prevent that

But that is a great idea, some visual feedback that a wall or gate has moved or opened

That lock is actuallty a little difficult to not lose a robot once the guard is in place, making saving the game very important

You need a robot that can find its way to and park right between the two fans and thrust both left and right at the same time, spinning the fans and opening the walls above the keyhole where a second robot can enter (by itself, no hiding inside it because of the sentry) with the key in its grabber and drop it when it reaches the keyhole

The puzzles in that level are meant to be hard af

It's the super secret sixth level

I spent weeks solving the purple lock the first time

And you also need to make sure you can get your robots back, other locks may need multiple bots

So many mechanics in that game, like every puzzle is a different set of them

[pine smelt]

how long have u spent on it so far

i cant imagine how long it would take to connect every puzzle together

[limber veldt]

Total time spent making the game? Oh man, a lot, hundreds of hours for sure

[pine smelt]

sounds about right lol

[limber veldt]

The first screen in the video, at like 2 seconds, is all items in the game, too

[pine smelt]

is that like a debug room or something

[limber veldt]

Not counting things from the toolbox (gates and devices like that)

Yeah

That whole level is a test

[pine smelt]

there are multiple levels?

[limber veldt]

Yeah, 5 regular and the super secret sixth plus the lab and about 8 tutorial levels, so about 14 total

[still violet]

Hello.

[limber veldt]

Hi

Walkthroughs of all the gates in one level, sensors in another, and so on

Robots, Circuits, Chip burning, all kinds of em

And the saves are level based, such that if you save in level 5 only that level is saved, for instance

Over 400 rooms total, nearly 500

And why it's my most ambitious project

[limber veldt]

After playing the game, one will definitely understand digital logic at some basic level at least

I have a playlist of me playing the 2000 remake (made in java) start to finish on my youtube, but I'll keep that secret for now : )

[past halo]

game called legend of moth i made https://pastebin.com/KwuhjHGg

[thorn knoll]

i added objectives now! any objective ideas? i want to get 5+ levels into my game

[hardy magnet]

maybe you could add some type of upgrade system like better / different trees that give more points

and a currency system to purchase the upgrades

[thorn knoll]

hmm maybe!

for now, any simple ideas? maybe i can add a speed boost to make it easier to catch falling acorns

"simple ideas" meaning things i can add to the objectives list

[thorn knoll]

yea maybe i could use points as currency (i'll make them available after level 2 of course XD)

Waiting for points to accumulate before spending it all on an upgrade is a bit annoying sometimes

[hardy magnet]

yeah

[thorn knoll]

anyway, got anything?

[hardy magnet]

maybe an objective to stay alive for x seconds?

[thorn knoll]

wait hang on

theres no penalty for missing acorns

besides time

[hardy magnet]

you could also do it like
plant 3 trees
plant 7 trees
plant 15 ... ... to like 100 or something crazy

so its like continuous

[thorn knoll]

so maybe catching x acorns in a row?

[hardy magnet]

yeah that could be a good one too

[thorn knoll]

actually, the game resets after each objective

[hardy magnet]

oh i see

[thorn knoll]

i also added fires too

they deduct 0.1 points a second

and you do not gain any points

while a fire is active

you also cannot pass the objective if a fire is active

[hardy magnet]

mabye you could store the users stats in a text file so players can keep their scores and stuff

[thorn knoll]

whats ur thoughts about this addition?

the theme IS world improvement soo...

ohh wait i just had an idea

i can make the first 3 levels a tutorial

the first one is "plant three trees" and the second is "grow three trees" and the third is "extinguish three fires"

[hardy magnet]

oh yeah good idea

[thorn knoll]

maybe a bossfight?

against a fire guy who shoots fire, and you have to counter it by shooting water with the water bot

and if you manage to hit the boss x amount of times you win

maybe that can be the final level

i already found some techsmart sprites for the boss, as well as the arena

maybe we can give the seed bot a role too but idk how thats gonna work

[thorn knoll]

@hardy magnet this is what i got so far

(Water and fire CANNOT spawn during level 1.)
(Acorns and fire CANNOT spawn during level 2.)

[hardy magnet]

ooh very cool

[thorn knoll]

still need to make one about extinguishing fires

will make around 3 fires spawn in and then only water can spawn after that

[thorn knoll]

added crystals to the game now

crystals set your Growth Points (GP) to 3

now, when an acorn is planted, it is automatically grown to a big tree in exchange for 1 GP.

if the player has 0 GP, then any acorns planted will become small trees.

[bold hill]

May I ask a question?

How can I make a crafting system?

[pine smelt]

depends on ur game

[dawn quiver]

Hello guys I’m just getting started with python /pygame

I need some help In creating a username passird screen

[bold hill]

DND style

[pine smelt]

do you have a screenshot of the game so far, im not sure how DND games look

[pine smelt]

what do you have so far

[dawn quiver]

I have drawn the rect for the username and password and have the headers for each box

Now I am trying to figure out how I can type in the box and validate the input

But can’t

[pine smelt]

live typing is tricky, u sure u cant use tkinter for that part

[dawn quiver]

What is tkintr sry I’m new to this

[limber veldt]

tikinter is a user interface thing, it has textboxes, entryboxes, dropdown menus, things like this that you can build and use. I wonder about pygame_gui though, I haven't really checked that out so I don't really know what it can or cannot do

[bold hill]

No I'm working on the basic mechanics first before I figure out how to do the main game for the players class and race for dragonborn etc

[lunar saddle]

What is the best package for game development?

[bold hill]

Pygame

[limber veldt]

pygame-ce, almost the same thing but the Community Edition of pygame

[floral quiver]

Im wondering on how I could go about making a map in pygame, like using blocks and placing them around in a specific order

Ive seen methods where people use something like this:

",""x"

Like , being an empty space

and x being a sprite

but no idea how to do this so if anyone knows please tell me how

[bold hill]

How can I assign specific traits to what I want for in a game because I want to make it warm if you choose an Archer as a class you're able to shoot arrows but for warriors you would have to learn that trait

class mage:
    def __init__(self):
        
        health = 100
        
        mana = 50
        can_use_mage_progectiles = True
        
        defence_spells = []
        
        attack_spells = []
        
        heal_spells = []
        
        traits = {}
        
        buffs = {}
        
        debuffs = {}
        ```
        Is this okay for a game class

[stable pasture]

searching for people that wanna code a recoil compensator for all types of games... DM me if ur interested !!!

[bold hill]

I'm not yet I'm working on the player class but I want to make it where it's customizable you have mage etc anytime during the races which would be dragonborn human halfling elf and dwarf

[manic totem]

what does it mean by "all 4 fields"
TypeError: Invalid rect, all 4 fields must be numeric

[pearl juniper]

Make sure you're passing exactly four numeric values, such as integers or floats, in the correct order
For example: rect = (x, y, width, height)
Each of the four values (x, y, width, and height) is numeric (integer or float).
No fields are missing or None

Hey guys! I am new to pygame and I found this sample code to move an object towards a moving player, but when i try it, the objects just accumulate at one point after a few seconds and collectively move towards the player, i kinda want them to spread out and like encircle the player, if that makes sense? Thanks 😄

[astral dust]

Hello, I was interested in this topic around 4 years ago, I was making games for terminal, but I implemented color images.

https://vk.com/video593927828_456239067

I can share code if u need, but I am sure most part is unreadable.

[astral dust]

What you mean ?

[vagrant saddle]

sounds like selling cheating program for various fps

[stable pasture]

i dont wanna sell anything, i just wanna learn methods cheaters use for my future anticheat

[vagrant saddle]

if you want to learn that kind of stuff : go write a C compiler / work on a risc assembly vm or wasm relooper you will learn as much : you will be legit and get a job

[vagrant saddle]

still R/E on a licensed cheat ( yeah even virus/cheats can be (c) work ) can be illegal in some countries

[bold hill]

Here's my code I'm working on the classes first before I get into anything of the true game

[bold hill]

@pine smelt

[spice vigil]

I dont see why not. Maybe try to put these classes to seperate files for readability

[bold hill]

How can I make it so that tracks the player? Sorry

[spice vigil]

What do you mean?

[bold hill]

What I mean is how can I make it intelligent to hunt the player

Sorry

[bold hill]

So having them have their own python file?

[spice vigil]

Yea

[spice vigil]

You can input the player position to the functions's arguments

[bold hill]

I've never done anything I like this so I don't really know how to use it sorry

[spice vigil]

Try learning from this video: https://youtu.be/2gABYM5M0ww?si=TinUvJSbBDJJkfBX

It is may be overwhelming but it is very easy to understand

You will get the basic understanding in that video

[bold hill]

Thank you

[limber veldt]

I think the easiest way to track a player (or any object) is 1: get vector from chaser to chased, that is vec = chaser.position - chased.position. 2: Normalize that vector. 3: set it as chaser.direction. 4: update chaser position. chaser.position += chaser.direction * chaser.speed * dt

[limber veldt]

A most basic demonstration ```py
import pygame
from pygame import Vector2

screen = pygame.display.set_mode((400, 400))

CLOCK = pygame.time.Clock()
FPS = 60

class Chaser(pygame.sprite.Sprite):
def init(self, pos, group):
super().init(group)
self.image = pygame.Surface((40, 40))
self.image.fill('red')
self.rect = self.image.get_frect(center = pos)
self.direction = Vector2()
self.speed = 200

def update(self, dt, target_pos):
    direction = Vector2(target_pos) - Vector2(self.rect.center)
    direction.normalize_ip()
    self.rect.center += direction * self.speed * dt

enemy_group = pygame.sprite.Group()
chaser = Chaser((200, 200), enemy_group)

while True:
dt = CLOCK.tick(FPS) * 0.001
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
raise SystemExit

screen.fill('black')

enemy_group.draw(screen)
enemy_group.update(dt, pygame.mouse.get_pos())

pygame.display.update()```

[limber veldt]

As with most of my quickie demos, pygame-ce required (for the get_frect() as opposed to regular pygame's get_rect() otherwise, we need to cast the chaser rect center ints to floats, do math on them, then assign them back to chaser rect center

Same thing but using get_rect() (this time with ZeroDivisionError checking before the vector.normalize_ip()) ```py
import pygame
from pygame import Vector2

screen = pygame.display.set_mode((400, 400))

CLOCK = pygame.time.Clock()
FPS = 60

class Chaser(pygame.sprite.Sprite):
def init(self, pos, group):
super().init(group)
self.image = pygame.Surface((40, 40))
self.image.fill('red')
self.rect = self.image.get_rect(center = pos)
self.pos = Vector2(self.rect.center)
self.direction = Vector2()
self.speed = 200

def update(self, dt, target_pos):
    self.direction = Vector2(target_pos) - Vector2(self.rect.center)
    if self.direction.length() > 0:
        self.direction.normalize_ip()
    self.pos += self.direction * self.speed * dt
    self.rect.center = round(self.pos.x), round(self.pos.y)

enemy_group = pygame.sprite.Group()
chaser = Chaser((200, 200), enemy_group)

while True:
dt = CLOCK.tick(FPS) * 0.001
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
raise SystemExit

screen.fill('black')

enemy_group.draw(screen)
enemy_group.update(dt, pygame.mouse.get_pos())

pygame.display.update()```

Notice how I use self.pos, a vector using floats for .x and .y attributes, as the position of the chaser instead of its rect.center. That's because get_rect() only supports ints and doing physics with ints is not precise enough, it loses the decimals on every update

[glass light]

Been working on some sneaky hidden rooms today

[limber veldt]

Oh nice, gotta have some hidden areas, very cool

The music, the graphics, the movement, it's all good

[glass light]

Thanks, it was actually super easy to do

[limber veldt]

The mechanics look like they're working great too

[glass light]

Hah yeah it's getting there. a year or two left I think. It's been a slog 😄

[limber veldt]

That's what I'm lacking in my robot game but it'd have to be less 'actiony` kind of music, maybe I just leave that to the player to run their own music

[glass light]

Yeah, if you can catch a good opportunity, humble bundle do some good music/fx asset packs

[limber veldt]

I never think of using steam for assets, I should check it out the next time I need

[floral quiver]

For my second ever pygame project I wanted to make a clone of the classic fruit drop game where you catch falling fruit. I learnt about using random here and worked out how to use buttons and a game over screen I think it turned pretty neat!

I messed up the button placement during the recording somehow 🤣. If anyone is interested in seeing the code let me know I can dm it

Oh yeah, if anyone has an idea on what I could do next as a challenge/project please let me know! (im still a beginner about 2 weeks in so dont make it too difficult pls)

[limber veldt]

Looking good...next project...hmmm, I don't know, maybe something with rotations, like asteroids?

[floral quiver]

Thats a great idea, challenge accepted!

[limber veldt]

Sending bullets at angles is a good thing to know

[floral quiver]

yeah thats gonna be tough im gonna try and break it down into as many chunks as i can and try and complete each one, thats my method.

[limber veldt]

Pro-tip, if not already learning them, start learning to use vectors for movement

[floral quiver]

Whats better about them?

[limber veldt]

They can be scaled to work with deltatime, math on them is easy, many many advantages. They are pretty much the industry standard for moving things in 2d space, like screens, and even 3d games

[floral quiver]

I remember learning about them in school lol.

[limber veldt]

Yeah, part of linear algebra

[floral quiver]

For movement like ive been doing which is just paddles i think just changing the y or x works but yeah for a game like asteroids i think that makes alot more sense

im gonna watch some vids on it now.

thanks for tips and feedback!

[limber veldt]

I learned a lot about them from a few youtubers, The Coding Train's Nature of Code series (not in python but the logic holds for any language, it's about the vectors, not the code), Freya Holmer, and a few others

And pygame has really useful Vector2 (and Vector3) classes and methods

[floral quiver]

as in they are already inside the pygame library so i dont need to import math or anything right?

[limber veldt]

Correct

They are in pygame.math.Vector2 but can also be accessed with just pygame.Vector2 which is why I usually just import them separately like so from pygame import Vector2 and can use it by that name anywhere

[floral quiver]

Vector 3 would be x,y,z so isnt that 3d?

[limber veldt]

Yep

[floral quiver]

so you can make 3d games in pygame?

i didnt know

[limber veldt]

I mean, not really but sometimes 3d vectors might be useful to some, I never use them

[floral quiver]

Oh right thanks i remember seeing this used once in a tutorial but i didnt understand the need to use it

Im gonna mess around with vectors for a while and try and get some sort of accelaration decellartion thign working

[limber veldt]

Good luck, fun stuff

[floral quiver]

yeah I find it really interesting actually but some of it just does not make sense at all to me 🤣

Happy pygame handles the complicated stuff

[limber veldt]

Take it slow at first, it's all part of the process

For a look at all the methods in pygame-ce's Vector classes https://pyga.me/docs/ref/math.html#pygame.math.Vector2

[limber veldt]

Things like this are probably my most used with vectors, getting the direction from something to another thing, pretty basic implementation too

But many behaviors like seek(), arrive(), follow_path(), all that stuff, is using vectors

Where to spawn the bullet with a rotating cannon...vectors can figure that out in like three lines

[limber veldt]

Aiming at and hitting a moving target, particularly difficult stuff like that, also vectors

[pine smelt]

strictly 3d is borderline impossible (unless u use opengl), i dont think u can ever make a modern AAA game

HOWEVER, people have made all sorts of pseudo-3d games

2.5D (literally any doom clone), isometric (bigwhoop's isometria) and sprite stacking (like fluffy's kart game) to name a few

[limber veldt]

Yeah, they can get things working in opengl contexts and stuff, but nothing I've seen yet is really mainstream

[pine smelt]

yeah

[limber veldt]

I've used Blender a few times to make and render images of 3d objects to be used as sprites in animations

And that's kinda cool, at least the sprites look 3d

Thought about doing it for chess pieces but blender sculpting (for the knight) was never my thing

All the other pieces are just fancy extruded circles

[pine smelt]

imo it wouldn't be worth the effort anyway, you'd only ever see one face of the pieces anyway

[limber veldt]

I'd probably tip them to an isometric angle but true, they wouldn't have rotation anyway

[pine smelt]

ye

[limber veldt]

Like this little ship that does a flyover during the intro to one of them, the path it follows and images all made in blender

The entire flight takes less than a second or so, but I had to have it

That original game was from like 1981 or so, if they could do it then, how hard could it be? I'm not sure how they did it but surely something similar

Here it is

[bold hill]

How can I difine a shape for the player?

[crude dagger]

i'd love to take a look if you can send it, nice work btw

[limber veldt]

I'm not sure I understand what you mean there but if you have a surface on which to draw your player, you could define points to use in pygame.draw.polygon() or any combination of the other pygame.draw.... methods and draw them on that surface

You could also pygame.image.load() an image

[astral dust]

Hello

I am making War Thunder like game on python, now I am working on penetration and modules damage simulation (very simple)

Anyone knows an article to read about this stuff

?

[keen flame]

Hi , is "Tkinter" library good for develop games?

If not please let me know which library is the best for making games in python

[tidal drift]

you may want to take a look at pygame-ce instead

[floral quiver]

Pygame-ce is great for 2d games, Ursina for 3d

[keen flame]

Ok , thank you so much

[floral quiver]

Could someone help me with vector movement in pygame I cant work it out

[bold hill]

Why mean is how can I define the player to be inside of the class itself sorry

[astral dust]

I can maybe

[floral quiver]

that would be greati

[astral dust]

Depends on what game is it 🙂

[astral dust]

Well, then send code

[keen flame]

I think I will start learning pygame

Although I'm not sure where I can learn it or even where I should start with

Probably self learning

[floral quiver]

I started learning 2 weeks ago

use youtube

[keen flame]

Only I know is

"Import pygame"

And that's all

[keen flame]

Can you send me good videos in DM so I can learn from them

I mean about pygame

[floral quiver]

Sure

[limber veldt]

Clear Code, DaFluffyPotato, a few others have good quality videos

[floral quiver]

Tech with Tim too

[floral quiver]

one sec

[floral quiver]

Hello sorry about that. I dont have any atm I was hoping to have help actually writing it and making a player movement script with acceleration ect but I cant find a good tutorial

[astral dust]

For example, I used tkinter to write this.

https://vk.com/video593927828_456239110

I used tkinter here because I wanted to draw in overlay

[keen flame]

Wow that's cool , but I heard from people that tkinter is not good for games

[astral dust]

I used tkinter here ONLY because I wanted to draw in overlay *

[astral dust]

In my case I haven't problems with fps and other things. But as I know tkinter works badly or doesn't work at all on linux / mac

[astral dust]

then open math schoolbook

[prisma gust]

Yo

Need some help

Im new to this server and to python

I dont understand python coding in the slightest

I wanna code a shooter game

On pygame

Or tkinter

[dusky grove]

Who needs developer?
I am fullstack, blockchain, game, bot developer.

[floral quiver]

Ok

[verbal kestrel]

Since no one replied I'll just say this. If you want to make something using pygame and tkinter you'd probably want to have a decent foundation first. There's tones of resources out there for learning.

[ruby acorn]

Hey

[limber veldt]

Playing around with seek() and arrive() methods, oh and also seeing what it takes to make a ghost behave like Mario's (facing away makes him chase you) https://paste.pythondiscord.com/CFTA

[limber veldt]

And a pretty basic asteroids ship with bullets, no enemies, no asteroids, no collisions https://paste.pythondiscord.com/A6MQ

[floral quiver]

Very cool

[limber veldt]

Thanks

[floral quiver]

I wonder how difficult it is to make the ship face the mouse

[limber veldt]

Not terribly difficult, just get a vector from the mouse position to the ship's and normailize then assign it to the ship's .direction attribute (all inside the get_input() method)

See how I'm getting the keys to rotate that vector?

Instead, get the vector from the mouse to the ship

[floral quiver]

yeah I think so

[limber veldt]

It could be a little more (or even a lot more complicated if wanted that way), but surely something could be put together quickly

[floral quiver]

Your code is so clean how long have you been making games in pygame?

[limber veldt]

Like I'm damping the rotation with the rot_vel attribute, implementing that relative to the amount of difference between where the ship is facing and where that vector points might matter but I doubt it, it's very little damping anyway

[limber veldt]

Python about 15 years, pygame about 5 or 6

[floral quiver]

wow thats impressive

I see now why your code is perfect haha

[limber veldt]

I dunno about that, there are others here that can do even better : )

[floral quiver]

everythign is in a functon

[floral quiver]

well I think its great compared to the "code" I write lmao

[limber veldt]

We're all somewhere along the path, keep practicing and anyone can be pretty good

Organizing code is a big part of keep it workable or at least making it easier to work with

[floral quiver]

I sure hope so just gotta keep motivated thats really what i struggle with

[floral quiver]

yeah readability is key

[floral quiver]

If you dont mind me asking what did you use python for before pygame?

[limber veldt]

Coding Blender's API

Well, making an addon for it

Among other things

It used to have a Game Engine built in, it's since separated from main Blender branch but somewhere along the line, I went to using pygame

[limber veldt]

It took me years to complete the addon, by the way

But I was pretty new at python when I started, some prior coding though, I've been ahobby coder for a looong time

For me, the motivation was really wanting or even needing to make that addon, no matter how long it takes

And of course, other ideas and projects happen since I learned allat

[floral quiver]

Oh okay so you dont code as a job

Fair enough

I think its a great hobby too so far

[limber veldt]

Nope, just practicing, always practicing and then practicing some more

It is fun, like I still get excited af when something really hard finally works

[floral quiver]

yeah its an amazing feeling even with small projects like my recent one where i made a main menu screen

[limber veldt]

Hell yeah

As for functions and methods, I feel like there's a sweetspot between making a long method with a few comments and just breaking out some of that code to other methods and the name of the method being the 'comment' or making it readable

Then you can kind of group things together in a logical way, probably takes a lot of practice though

How can I blit a class onto the screen sorry

class player(races,classes):
    #player_body = pygame.rect((150, 150, 50, 50))

    
    comanions = []

    inventory = {}
    pass

[limber veldt]

Make it a sprite, add it to a group, draw the group?

[bold hill]

I still need to work on figuring out how to draw sprites why I mean is drawing the character object itself onto the screen

[limber veldt]

That's what sprites and groups do, draw objects

Sprites have .image and .rect attributes. The .image attribute defines what to draw and the .rect defines where to draw it

[bold hill]

I don't have a Sprite seat sheet yet I'm going to do that later I just need to make sure everything's working and I'm letting it onto the screen

[limber veldt]

They don't always have to be in a group, you could just screen.blit(sprite.image, sprite.rect) in your main draw() method, too

You don't need a sprite sheet to make a sprite

[bold hill]

I managed to add a player movement in the class no I just need to call it to draw the player and game all the information from the class

class player(races,classes):
    player_body = pygame.rect((150, 150, 50, 50))

    
    comanions = []

    inventory = {}

    key = pygame.key.get_pressed()

    if key[pygame.K_a] == True:
        player_body.move_ip(-1 ,0)

    elif key[pygame.K_d] == True:
        player_body.move_ip(1 ,0)

    elif key[pygame.K_w] == True:
        player_body.move_ip(0 ,-1)

    elif key[pygame.K_s] == True:
        player_body.move_ip(0 ,1)


#===[monster classes]===#
class monster:
    pass

class vault_monster(monster):
    pass
#===============#

running = True

while running:

    pygame.draw.rect(screen, (0, 0, 255), player)

[limber veldt]

How is this class going to work? It has no __init__() method or nothing instancing it

[bold hill]

That's what I've been forgetting I've neglected to even put a basic initiate

[bold hill]

I'm out in the initiating definition now I just need help trying to blend the player body which do I have to put self into this definition

class player:
    def __init__( player_body):
        player_body = pygame.rect((150, 150, 50, 50))

    
    comanions = []

    inventory = {}

    key = pygame.key.get_pressed()

    if key[pygame.K_a] == True:
        player_body.move_ip(-1 ,0)

    elif key[pygame.K_d] == True:
        player_body.move_ip(1 ,0)

    elif key[pygame.K_w] == True:
        player_body.move_ip(0 ,-1)

    elif key[pygame.K_s] == True:
        player_body.move_ip(0 ,1)

updated player class

[limber veldt]

A very basic player sprite, just a rect that can be moved around the screen https://paste.pythondiscord.com/2SYA

It has an update() method that is called from the group by player_group.update() at line 77, that's all it need to update it, and is drawn by player_group.draw() at line 74, that's all it needs

Since it has an update() method, we can read the keys inside the class itself with the get_input() method, assign the direction and update the position of the sprite

[bold hill]

I'm not going to get into inheritance yet I'm just trying to find a way of getting all of this to work without driving me crazy

[limber veldt]

You are already inheriting from races and classes, so why not make a sprite? Or were already

Totally up to you, sprites and groups make this a lot easier. You asked how to draw a player with a player class that won't really work the way it is

[bold hill]

Thank you I am sorry

[limber veldt]

Like how are you going to call these lines to read the keys?

If you want to use classes in pygame, I strongly recommend learning how to subclass pygame.sprite.Sprite and pygame.sprite.Group()

Sprite especially

It's really only two attributes in the sprite itself, the .image and .rect attributes, that's all you need to make anything a sprite

For me, that's much of the advantage of using pygame, the sprites and groups (along with all the other things, event loop, vector methods, so many)

[limber veldt]

As for the 'without driving me crazy' part, maybe watch some tutorials showing how to do this. Clear Code is among the youtubers I always recommend because he almost always uses pygame sprites and shows how quite clearly

Anyone interested in collaborating on a browser game? The structure of it has been completed and the base backend and frontend is already coded. I'm having some issues with my routing/redirects. There is a GitHub and everything. I just could really use a hand.

All the ones I have found on Youtube all import a lot of things and use external things like py.game and I am not allowed to use that on this project for Uni work.

[restive pollen]

Don't know much about game dev in particular, but in your shoes, I'd learn what I could from tutorials on text based game development in python and then use ChatGPT as an advisor to help structure your code (although that might be a no no for an assignment...). I'm guessing that getting the game loop and data structures right are going to be the most important parts of the game design, and those probably don't differ too much in structure with 3rd party packages. But again, not an expert

This is outside of the player class I'm not going to work on spray sheets yet because I don't have any I just want to make sure that this works I might need the code for a Sprite sheets but comment that out later till I can find something that fits sorry

[astral dust]

Is it Player class ? If it is, then you should read about OOP and write self.player_body instead of player_body.

[astral dust]

It takes too long to load web application.

[astral dust]

Missed the message. Yes, just replace player_body to self.player_body.

[bold hill]

Like this?

[astral dust]

You cann't write code outside functions in classes. Learn basics and then try to make games.

I have I just have a hard time understanding classes and I thought a game would help because in essence it's just a package not you but in code to tell the computer what to put onto the screen and how to do it

[astral dust]

Save time

[astral dust]

To understand classes, do not import anything, just work in IDLE. Try to write classes of objects near you. Play with inheritance and functionality. For example: container -> cup -> cup_of_tea

[vagrant saddle]

takes about the same time to load godot or unity

[astral dust]

That's why most popular and playable web games, as I known, written on JS (and frameworks), examples: suroi.io, diep.io, slither.io and many others.

[astral dust]

The main advantages of browser games are simplicity and low performance needed

[vagrant saddle]

that is certainly not related to use of JS+framework, but more game type and target ( webgl1/2 instead of potato )

[astral dust]

short page loading period *

[vagrant saddle]

yeah more like that, which on second run has no impact

because everything gets cached

[astral dust]

First impression and experience rule

[vagrant saddle]

experience says make attractives loading screens, wonderfull packaging and spend everything on marketing

if people can't wait for a free web game to load, they don't deserve the fun

[astral dust]

big part of web players are people with very slow internet

Here is the whole script

Its supposed to print the vector values in the output

Please ping me when replying

@limber veldt Any ideas?

[astral dust]

Show whole exception text

including number of line

[astral dust]

put .x here https://skrinshoter.ru/sSYEPeJY3EL?a

do same with direction.y

[floral quiver]

Thanks

But for some reason pressing do doesnt do anythign

but the others work

Sorry pressing "d" doesnt do anything

Oh I see its becuase i forgot to add print to it

all fixed thanks for help

[warm mortar]

Anyone interested in collaborating on a browser game? The structure of it has been completed and the base backend and frontend is already coded.

There is a GitHub and everything. I just could really use a hand

[vestal iron]

how to deal with offset problem. Image just starts going up and down constantly
like if condition met i move image up if not i revert back. But if i place my mouse at the bottom image it constantly offsets and return to original position

ping me if you got something

[limber veldt]

Nice start on using Vector2(). One thing I'd point out is that after setting direction, when all is done, it's a good idea to normalize the vector if its length() is greater than 0. If we think about it, we can realize why. When moving left, right up or down, we move 1 pixel at a time because that's the length of our vector, (1, 0) or (0, 1) for the x or y makes that length == 1. If moving right AND down or and up (or any combination of two directions) we get a vector of (1, 1) (both one for x and y of the vector) which makes the length() of our vector 1.4 or so, not 1, and faster than moving just one direction. vector.normalize_ip() will make that 1.4 length vector the length of 1, making all directions move at the same speed, even if at an angle

[floral quiver]

Yeah ive been messing around with them for a while, I managed to get the square to move, but really struggled with normalizing so I had to search it up 🤣

[limber veldt]

Good for you, making good progress and looking things up

[floral quiver]

My next goal is to get friction and some sort of acceleration to work but its kinda difficult

[limber veldt]

Integrating motion over cartesian coordinates (screen pixels) might lead to some hits. But yeah, integrating acceleration, velicity and position is what's needed

[floral quiver]

I brb

[limber veldt]

So for that (acceleration), we usually don't affect the vector directions directly, like setting .direction.y or .x to some value. Instead, we affect acceleration and that gets added to our .direction vector. But there are many ways to accomplish this kind of integration nd me describing it here isn't one of them

I kind of faked it with increasing and decreasing .speed the scalar that I use to scale the normalized vector to our movement speed

Using two scalars on our position when adding our direction vector gives us that flexibility. position(a vector) += self.direction (a normalized vector) * self.speed (a scalar. .ie: a float) * deltatime (another scalar)

[floral quiver]

Hmm I would have to try this out

Would you use a class for handling movement becuase you self.direction?

[limber veldt]

I would keep movement of player inside a player class

All things affecting player should be in the player class but this is not a strict rule, you are totally allowed to affect player attributes from outside the class

[floral quiver]

Ive never actually used a class I think I know how to use them but at this stage i dont really see the point in using them

[limber veldt]

And that's fine too, but just know that classes will help keep your code clean. For now, at this stage of your adventure, you have discovered them, and kind of know what they are and sort of know how to use them at least a little bit, it's fine, in my opinion, if you would rather work on learning mechanics of motion and all that kind of stuff first

[floral quiver]

yeah

My code is messy atm but after I actually learn I plan on cleaning it up with functions, classes ect

[limber veldt]

Discovering what can be done is a big part of learning, but practicing what you have already discovered is probably more important

[floral quiver]

Is delta time necessary?

[limber veldt]

Yes

Again, something that will serve you better later than now

[floral quiver]

Oh okay I always thought it was only if you wanted your games to run at more fps

So it looks the same no matter the fps

fram independant or something

[limber veldt]

It's good in that if your game is ever ran on a faster or slower machine than the one you are currently running it on, delta time will keep the apparent speed of motion, the speed on the screens, consistent

Yeah, framerate independence

[floral quiver]

But so would lockign it to 60, no?

[limber veldt]

Yes

[floral quiver]

I'll look into adding it soon too but its very complicated right?

as in not complicated to add but how it works behind the scenes

[limber veldt]

It's mostly important for speeds dropping below that 60 fps, being higher than that and our framerate will be fine at 60

No, not at all

See the dt = something in my previous examples?

That's all I do for calculating it (in milliseconds)

Properly initializing and re-assigning it each frame isn't terribly difficult either but since pygame has a .time object and it's giving us that value with a simple call, I use it

[vestal iron]

I heared pygame .time doesnt give accurate time

like the more decimals you have the more accurate you are

[limber veldt]

Some say perf_counter (part of the python time module) is more accurate

[floral quiver]

Honestly for the small games im making right now your pc would have to be from ancient egypt to get below 60 fps

[limber veldt]

And same here

[vestal iron]

what games you making?

[floral quiver]

NOt even games just little projects to learn

[limber veldt]

Some of my games might get a little heavy on slower machines but the vast majority, those without a hundred enemies on screen at a time and each of them searching for the player, keep a steady 240 fps most of the time

[vestal iron]

nice, im making an unique card game, pretty hard honestly, sitting 4 hours deep on some small bug xD

[floral quiver]

Wow sounds comlicated, yeah I picked python and pygame like 4-5 weeks ago so im really new

[vestal iron]

oh nice, its complicated even for me being 2-3 years into programming cuz programming is easy but you need good logical thinking lots of math skills

[limber veldt]

I have literally hundreds of those through many years, many not even on my drives anymore (but in backups surely, somewhere)

They are so valuable

[floral quiver]

Yup

[limber veldt]

To me at least

[floral quiver]

Wow I think at this rate ill be in hundreds too in a few years

[limber veldt]

All little sign posts along the path I've mentioned before

[astral dust]

modular damage system

[limber veldt]

Interesting video

hey @vestal iron , I'm curious if you got your state machine working (I think it was you asking about them a few days ago)

[vestal iron]

yes i was, that guy really helped me a lot 😄 , i got it working, its simpler than what i used to do but mine was overcomplicated thing, thats my downside, i dont know how to do simple

[limber veldt]

Those (state machines) are awesome logic helpers. For me, I like that any attributes or special logic for one state is completely separate from any other state, therefor encapsulating logic to each state

[vestal iron]

you know one things is to know theory another thing is apply in practice

[limber veldt]

That's good, rock on

For sure, that application part is often much harder

[vestal iron]

like recently im pushing myself to make a mess of my code cuz its not ok refactor your state machine a month 😄 nothing gets dont so at least its for me i have to learn to make a mess

[limber veldt]

lol yeah, refactoring takes time

[vestal iron]

its not about the time it takes to refactor, my problem is that im perfectionist, and refactoring plus that is hazardeous combo

[limber veldt]

This is my basic state pattern. Sometimes I implement a .next_state attribute too and change the pattern slightly, but it works. I'd love to learn more ways to do it, like using an Enum instead of a dict for the states (among other improvements) https://paste.pythondiscord.com/C4VQ

And those states aren't doing anything either, only looking at the pattern there

Just counting time and switching to another state to count more time

In fact, there's a typo in it, but it's ok, it's not meant to be ran

Also shows why I consider delta time pretty important for things that move, it gets sent to and used by everything that animates motion on screen, or any kind of timing pattern

[vestal iron]

There is a website about patterns and there is state pattern example in OOP way. Im giving heads up that they love abstractions and overcomplicating things.

https://refactoring.guru/design-patterns/state

[limber veldt]

A quick little project, seven segment display that changes its segments depending on keypresses https://paste.pythondiscord.com/674Q

Wanna make a digital clock? That's the start of one

Oh that line 81 is unnecessary, remnant from a previous iteration of the code

Hmm, I like this more, keeping the group and the method to draw it inside the SevenSeg() class https://paste.pythondiscord.com/QRQA

Another quickie side project for my library of them

And it's already been refactored to lose the long lists and instead iterate the keys to instance all the Segment()'s

Like so ```py

    self.segments = []
    for key in directions.keys():
        self.segments.append(Segment(pos + offsets[key], directions[key], self.seg_group))```

Could even make that a comp but it's short enough already and easy to read

[limber veldt]

With a few more args and a little more logic, its size could be a parameter

Also would be handy to have an increment() and decrement() method

[limber veldt]

Could even use that in another class like NDigitDisplay() and make it that many digits with functionality to set values or increment/decrement current values

I've made digital clocks in Logisim before (with gates, converters, other stuff), so not a completely new idea

[floral quiver]

this is really cool, what could this be used for?

[limber veldt]

I dunno, some kind of counter, maybe a score keeper for a retro game

[floral quiver]

those numbers you made there seems realyl complicated to make lol

[limber veldt]

Turning off or on certain elements?

Yeah, much easier with code than with gates

[floral quiver]

I mean the actual surface

[limber veldt]

Gates way

[floral quiver]

uh

is that for a circuit board

or smth?

[limber veldt]

Yeah, a logic circuit

[floral quiver]

So what exactly is a state machine

it prints or displays states on certain input like numbers?

[limber veldt]

I pattern of coding such that there are a finite number of states an object can be in at any one time with transitions to and from other states

The state machine I use for the Segment() there is a pretty simple one, it does nothing but change the image of the sprite during each state's initialization then just idles because the .init_state variable is immediate set to False

It doesn't even need to be a state machine, since it has zero functionality actually in the states being updated constantly, but I started with it because I wasn't sure where it was going

If it had some kind of timer running in the states, they'd make more sense but I've instanced it in another class that can do timing things if necessary

And update the Segment()'s

[floral quiver]

It sounds really complicated to me but im sure one day ill understand.

[floral quiver]

I was wondering too, is it possible to set the caption on the window in pygame to the current fps?

[limber veldt]

Not too bad, just remember that state machines have states that can run in any kind of sequence or by triggers

[limber veldt]

Yes pygame.display.set_caption(f'{CLOCK.get_fps()}') assuming CLOCK is an instance of CLOCK = pygame.time.Clock()

[floral quiver]

Thanks

[limber veldt]

I usually put that line right after the while True: starting the main loop, so it's updated at every loop

[floral quiver]

Read my mind 🤣 I was about to ask why it wasnt working

[limber veldt]

Anywhere in the main loop is fine, but just once somewhere there

[limber veldt]

Looking through old videos, this one from early 2023 or so. Testing how the small swarm moves, collision with the ship disabled but their mines can hit it, invincible is on...

Bigger swarm

And a massive swarm

That's me just spawning and ramming the enemy that splits into a small swarm about 8 at a time right in front of the ship

[floral quiver]

I will check it out later im in a library and the internet is awful

Videos wont even load

[limber veldt]

That's ok, it's only me reminiscing anyway

[limber veldt]

Same functionality, no state machines https://paste.pythondiscord.com/LBXA

Pretty sure there's a .ttf font out there that can make it even easier

But that's cheating, lol

For an actual project, something much bigger and already taking time, I'd probably use a font

[shut plume]

how do i open the images which are inside the assets folder

[pine plinth]

project 1/assets/...

[floral quiver]

yeah thats what I thought

[crimson lava]

Is it possible to write a macOS screensaver using Pygame? On Windows, you can just use pyinstaller to compile it as an exe and change the extension to scr, but how can you make a screensaver using Pygame on Mac?

Does it HAVE to be written in Objective-C?

[raven kernel]

Probably something along the Mac ecosystem

It's already not known to be customizable

[vagrant saddle]

it is totally possible, but easy/simple NOT

[mellow flint]

average apple software flexibility

[vagrant saddle]

i you get to display a .bmp at 60 fps in a loop in your screensaver in objc, i will give you the C code that will run your pygame code

eg pure pygame code like this one https://pygame-web.github.io/showroom/pygame-scripts/org.pygame.touchpong.html ( do view source in tab )

[vagrant saddle]

that c code has no support for input or sound, never thought someone could use it, but screensaver fits

[manic totem]

so there this function inside the Enemy() class that can make enemies shoot and this function is the one responsible for spawing an enemies. so the question is how do i implement the function that can make the enemies shoot to 1/3 of enemies in range(10)

def create_enemies():
    X_position = [100, 200,300, 400, 500]
    Y_position = [-100, -200, -300, -400]
    exist = []
    random.shuffle([X_position, Y_position])
    for e in range(10):
        while True:
            x = random.choice(X_position)
            y = random.choice(Y_position)

            if [x,y] not in exist:
                exist.append([x,y])
                enemies = Enemy(x, y)
                enemies_grup.add(enemies)
                break

[nocturne lance]

if i wanted to make a full blow game in python how would i go about that?

[frail copper]

You would first have to get the hang of python then learn pygame @nocturne lance

[raven kernel]

I'd suggest this as well for 2D games ^

[sweet inlet]

Quick question. Im working on a game called Airborne : Python. It's a complex text based flight simulator. If I need help with the development, should I request for help here or in #1035199133436354600 ?

[vital mountain]

Is there some kind of JIT scripting language that can compile c++? I'm pretty sure I'm asking for something absurd, but a scripting language that can instantiate c++ templates for example.

[vital mountain]

Id tell you to not learn game development with that objective, and would tell you to learn another language that is far better for game development.

Python is not good for game dev, it's a really nice language but it's not made to perform time critical operations

You will also get fewer game dev resources if you do it on python, but I may be wrong

[floral quiver]

You can still male reallly cool games with it

[round obsidian]

people's ideas of what games are seem terribly distorted by AAA-style gaming. you can make some pretty impressive stuff in just PyGame and vanilla Python

[limber veldt]

And, in the process, learn some basic (even advanced) game mechanics ideas, how to animate things among others, and carry much of that over to any language

[sweet inlet]

I think, that just because Python comes with an in-built library called Pygame doesn't mean it's actually recommend to learn. If you want to get into professional game development you should start with Godot, Unity, Unreal, etc. Why waste time learning Pygame when you can start with the big engines?

One of the biggest problems I currently have, being self-taught, is wasting time learning something and then realising that that knowledge will not help you later on.

[round obsidian]

1. PyGame is not in-built, it's a third-party project
2. You can start learning anywhere. The point is not to make a polished, commercially viable game out of the gate; the point is to start somewhere and learn. If people begin with Godot, that's fine too

[vital mountain]

Never denied that, but I think people can get bad ideas from it.

[sweet inlet]

Yup. Think one of the biggest mistakes I made was starting with Python. Should have started with C++. Now that I know a bit of Python I don't even know what to do with it.

[round obsidian]

nobody's stopping you from learning C++, go see what it brings you

[normal silo]

The fundamental misunderstanding is that not using Unreal or some other big fancy engine is what is preventing them from making such a game, it's not. It has nothing to do with programming even, the problem is assets, no single person can make all the required assets in a reasonable time frame. This is why "AAA" game devs focus on having a ton of assets / looks / music / sound, the main advantage that they have is lots of people to make these in parallel.

While engines like Unreal are providing a ton of "free" assets, your game will look terribly generic (which is also becoming a problem for many "AAA" devs that have switched to Unreal).

Using something like Pygame can actually make even more sense for a solo dev with a smaller scope game. There is less to learn with Pygame and better iteration speed than with something like Unreal, allowing for more time for assets and gameplay (not trying to compete on just assets/visuals/etc, but instead focusing on the part "AAA" seems to be lacking, gameplay).

[gentle junco]

hi i need urgent help with my game, is anyone willing to go through my code and help?

[floral quiver]

Yep I 100% aggree

[cosmic olive]

People usually prefer you to send the problem instead of just asking for help. It's so that they can see the scope of the problem first before deciding to help

[gentle junco]

ive done that the past like 10 times and nobody helped😭

[cosmic olive]

10 times? jeez. what kind of problems do you face 😂

[gentle junco]

im making a very simple ai for a fighting game

and my 'ai' was bugging out and throwing infinite punches

but i think ive fixed it kind of now

was stuck on this for waaay too long

[cosmic olive]

It be like that from time to time lol

Have you ever tried using the dedicated help forum tho? Those usually help whenever I'm stuck

[gentle junco]

yes atleast 10 times id say haha

[cosmic olive]

lol

tough luck

[floral quiver]

Made a platformer map. 1 = block and 0 = air

Might add more blocks

and a player

ik it looks scuffed im working on it lol

[raven kernel]

love to see it :)

great screenshot choices

[limber veldt]

Nice, looks like a good start to me

[sweet inlet]

Bugs are weird. Idk what's going on here but if anyone can explain I'd be grateful

It doesn't work without the text having an indent

Never mind. It goes back to normal after a add a space after the first backslash for the E.

[sturdy arrow]

This is great. Can you make the levels randomly generate by using this process?

[junior osprey]

@sweet inlet What app is that?

[vital mountain]

Not trivially

[floral quiver]

No idea how, but probably

[quasi hamlet]

not doing a random.choice per each grid, but you still could quite easily

[vital mountain]

well yeah its just a tile grid dude : |

[bold hill]

Is there a way of making a field where a player won't be able to get outside of a box cuz I'm trying to make a submarine kind of game after I make a player class which I need some help trying to pack it onto the screen I tried that with a game earlier

[dawn quiver]

anyone need a programmer for the November pygame jam?

[pine smelt]

the team creation channel will open in a couple days if ur still looking for a team by then

[limber veldt]

Curious, do (or will) you have an entry this time?

I won't but maybe next time

[proud elm]

This one is interesting

[sweet inlet]

I use Pydroid3 for Python related activities

I use Termux as a CLI emulator for my android

[pine smelt]

I'm quite loaded with work at the moment but I'll definitely try attempt it

it definitely won't be as big as my last jam game but experience is experience

[bold hill]

How can I make a partial system?

[trim cave]

partial system of?

[bold hill]

I need help making particle system for my game to run in the background since it's going to be a submarine-based game

[bold hill]

#===[imports]===#
import pygame
#===============#

class particals_system:


    def __init__(self,pos,particalX,particalY):
        
        self.particalX = particalX
        self.particalY = particalY

        self.pos = pos

        pos = particalX + particalY

        particles = []
print(pos)

[dawn quiver]

What do you mean by run in the background?

[dawn quiver]

If you are using pygame I recommend using pygame.math.Vector2 for positions.

!d pygame.math.Vector2

[frank field]

pygame.math.Vector2

pygame.math.Vector2```
 a 2\-Dimensional Vector Vector2() \-\> Vector2(0, 0\) Vector2(int) \-\> Vector2 Vector2(float) \-\> Vector2 Vector2(Vector2\) \-\> Vector2 Vector2(x, y) \-\> Vector2 Vector2((x, y)) \-\> Vector2

Similar names: pygame.pygame.math.Vector2

[dawn quiver]

If you want bubble particles Id give each particle a small force upward and a force that oscillates from left to right.

!d pygame.draw.circle

[frank field]

pygame.draw.circle

pygame.draw.circle()```
 draw a circle circle(surface, color, center, radius) \-\> Rect circle(surface, color, center, radius, width\=0, draw\_top\_right\=None, draw\_top\_left\=None, draw\_bottom\_left\=None, draw\_bottom\_right\=None) \-\> Rect  Draws a circle on the given surface.

Similar names: pygame.pygame.draw.circle

[dawn quiver]

!d random

[dawn quiver]

the big bubbles should in theory float to the top faster than the smaller ones

What could be cool looking is marching squares. So that the bubbles morph into each other.

[bold hill]

What I mean is the system having this particle system to make it feel like the person's underwater

[dawn quiver]

This any good?

[bold hill]

Yes

[limber veldt]

A particle system, to me, is a sprite group with sprites that have their own movement and it stays relatively consistent until the particle dies, either by leaving the screen or by living beyond its lifetime

[limber veldt]

Nice quickie bubbles, btw

The until it dies part is kind of important for particles because if they never die, they will start adding up (in memory)

Or any sprite(s) for that matter, when they leave the screen or you're done using them kill() them

Bullets, things like this

Bubbles

[dawn quiver]

Another thing that could be added is darker and lighter bubbles to get a sense of depth

[dawn quiver]

also these bubbles are very much in sync

[trim cave]

this is pretty cool

[floral quiver]

You just made this? Looks really cool

[graceful yew]

anyone familiar with this situation in pygame?
this will display the image on screen just fine:

class MonsterInfoSprite(Sprite):
    def __init__(self, rect: FRect, icon: Surface, groups: Sequence[Group]):
        super().__init__(*groups)
        self.image = icon
        self.rect = self.image.get_frect(topleft=rect.topleft)

but not this

class MonsterInfoSprite(Sprite):
    def __init__(self, rect: FRect, icon: Surface, groups: Sequence[Group]):
        super().__init__(*groups)
        self.image = Surface(rect.size)
        self.rect = self.image.get_frect(topleft=rect.topleft)
        self.icon = icon

    def update(self, _):
        self.image.fill(WHITE)
        self.image.blit(self.icon, self.rect.topleft)```
why?

[pine smelt]

wuts the error

[graceful yew]

nevermind, I found the bug - for blitting onto a surface I have to remember that the default position of (0, 0) is not the same as the window's (0,0), but always relative to the surface that calls blit()

kind of obvious in hindsight, but I got beaten hard by my own expectations

[pine smelt]

oh right it happens

[pine smelt]

i made this system for one of my games if ur interested?

[mortal glacier]

Here’s my lil roulette wheel if anyone wants to play it

https://paste.pythondiscord.com/ZRWA

If you have any ideas for it feel free to add them

[limber veldt]

Very cool effect, maybe smoke or even fire with the right colors

[limber veldt]

Maybe entering the number 1, 2, 3, 4 and so on should choose the option it represents

[mortal glacier]

Bet

So like, if you wanna bet on color, you put “2”

[limber veldt]

Sure

[mortal glacier]

Then it asks color and bet

[mortal glacier]

Not sure, what did you have in mind?

[limber veldt]

What do you mean? Entering the number should choose an option

Also, when entering color or bet or other values, maybe put the allowed values in the prompt...or use multiple while loops and inputs to get the choices instead of sending the player back to the start menu for not knowing the minumim bet is 100

Where I’m from, “Sure” usually means that person is settling in a scenario like this

[mortal glacier]

That makes sense

[floral quiver]

Dude this is amazing I hope I get this good one day

[limber veldt]

It was used to confirm what you said in the previous post, as in sure, why not (do what you said)

[mortal glacier]

Ok

Sorry for the misunderstanding

[limber veldt]

All good

[dawn quiver]

Awesome it uses marching squares?

[pine smelt]

no its the most small brain solution ever

draw the white circles first, then inner circles after

i could optimise it but for my use case 600 particles per area at 60fps was good enuf

[pine smelt]

actually, it came from a fire thing i was making that came out a torch

just modified the colours and particle velocities

[dawn quiver]

oh i see. very cool.

Hey guys, I though some of you may find this interesting, I am building a turn based strategy game and we are doing it using our own in-house graphics engine, it’s entirely in python and we have been really working hard over the last few months on it. But since it’s entirely in python I was like hey these guys may enjoy it https://terra-tactica.com

here’s my updated Roulette table. I know it’s got some bugs, but I’m too tired to fix them right now, so if you want to go ahead, if not, don’t. I don’t really care what you do, just please someone try it 🙂

[mortal glacier]

That looks dope, what’s the basic storyline about?

[candid blaze]

It’s open ended and completely up to you like Civ, Age of Empires, Stellaris etc

[candid blaze]

We are looking for devs on this if anyone is interested and willing to stay on it long term

[mortal glacier]

You don’t think I can be a beta tester, do you?🥺

[mortal glacier]

I’d love to help you make it, but I’m not that far yet

And I don’t know how it would work out with child labor laws

guys is there some of you thaT could just help me, my game looked ok and it kinda worked like i could walk around and stuff. i was just finishing my first little biome and my yt tutorial said i should add some kind of bounderies to my camera to make it smoother. i did that and now its just grey and zoomed out

[pine smelt]

need code to help

[sweet inlet]

Ahh yes, when everything works nicely but an attempt at perfection results in disaster. Very relateable

[tepid frost]

but can u help?

[sweet inlet]

Sorry buddy, nope

[candid blaze]

Work backwards, see what thing you added caused it. Once you figure out the cause then you can develop a solution easier.

[rotund vigil]

What libraries do you use for that game?

[tepid frost]

yeah but i think it was like only the camera

[foggy python]

Pygame and ModernGL

nice, is source available ? why not Panda3D for the 3d viewport ?

[austere flint]

no not yet want to stabalize the project a bit more before releasing the source
i manly want to have full control over everything related to the rendering and also wanted to do it myself lol

@foggy python hi, you mentioned you are using moderngl for your game yawnoc, does it replace the pygame framework?

[limber veldt]

Likely using an opengl context pygame window or display, along with the event loop and a few other pygame features and some shaders using moderngl

He has some tutorials/videos showing some of the process on his yt channel

[graceful yew]

thanks, I will check these out

[limber veldt]

Of course, I don't mean to speak for him but I offer my thoughts on the subject, maybe he can see the question some time and give us more information

I need to learn some of that, shaders for fx

Again showing that pygame is quite capable of making quality 2d games

[foggy python]

I just use it for post-processing. Most of the rendering is in Pygame.

[limber veldt]

Looks really good, nicely done again

[lusty pine]

My wife has somewhat of an interest in AI art so sometimes her art looks ai-ish. I think she does it on purpose lol

[lusty pine]

I really appreciate you all giving my game a try, I feel like none of the stuff I ever make lives up to what I wish it would

[vagrant saddle]

btw pygbag does not convert game to javascript, it runs it normally with cpython webassembly instead https://www.youtube.com/watch?v=oa2LllRZUlU

Fascinating! Thanks for sharing. I'll give this a watch

[muted sand]

Hello! I'm a CS freshman in college and have recently gotten into game development with PyGame. Today I finished a class I've been working on called "AnimationController" which is meant to handle all the animation logic for an object or character in my game.

All the code is explained in the project, but here's a basic explanation: each class in the game has an attribute called "animation dictionary", which contains the name of each animation along with methods and attributes related to that animation. These include a method that will determine if animation conditions are met, a method that will run as long as the animation is playing, the animation priority, and the actual sprites of the animation. The AnimationController will use this information to correctly determine which animation and frame should be played.

I'm relatively new to Python and especially game development, so if you have any feedback or suggestions please let me know!

Below the class I have an example object to demonstrate how the AnimationController works. It has a basic loop and some basic PyGame setup to allow keyboard input and prints out to the console the animation, the animation count, and the current sprite (which right now is just a string; in a real object it would be images). Try it out and see how the output changes when you press "a" or "d" to run, and "e" to attack.

https://paste.pythondiscord.com/CRKQ

[junior osprey]

Thank you!

[graceful yew]

delegating sprite animations to a dedicated class seems like an interesting idea, could be useful if you need to play a number of separate animations in specific order. I'm new to gamedev myself, and by following yt tutorials I learned to do animations by creating an update function for the sprite class and a draw function for the sprite-group class, which would have a reference to the sprite and thus be able to draw the surfaces referenced in the sprite

[sweet inlet]

This has got to be the latest reply I've ever received 😭

Welcome, and I'd recommend Termux as your terminal emulator

[velvet birch]

can u plz chelp me ive been trying to solve 3d sorting since forever
https://paste.pythondiscord.com/74WQ

[muted sand]

You may get a better response in #1035199133436354600 because you can create a thread that won't get buried underneath new messages

[muted sand]

The nice thing about having a class handle it is a lot of the repeated code can be left out, so adding new animations can be done with just a few lines of code. It also helps avoid errors

[muted sand]

Today I finished up another important class I've been working on: the InputController for the player. Code is explained as before, but here's a breakdown:

The player has an attribute called input_dictionary that stores an input along with attributes for the it. The InputController takes the player object and uses these values to determine when the method for the input should be called. Sometimes you'd want the method to be run as long as the input is held. Sometimes you only want it to run when the input starts. Sometimes you don't want to run the method until a certain condition is met. All of this is handled within the object and makes adding controls much simpler and quicker than writing all of that code within the player object itself.

Give it a read and tell me what you think. The only thing I might change is how the attributes are obtained, because right now it's kind of a mess lol, index within index within index. Logic is sound though. There's also an example below, so feel free to compile it and try it out. A and D make the player run when they're held, E makes the player attack and has a cooldown, and SPACE makes the player jump (although there are no visuals to accompany these; they are all printed to the console for the example)

https://paste.pythondiscord.com/QSPQ

[muted sand]

While it isn't what I originally intended, I did create a collision controller for my game. I originally tried to use masks - I don't believe I fully understand how they work or how to use them because it didn't go well, so instead I used some information about the object rects to make collision work.

Something I was able to get working is having the controller predict where your next position would be and handling your position accordingly, as opposed to putting you inside the object and then pushing you out. It takes the x or y velocity of the player and adds it to the player position (not setting the player position) and determines if that new position would put it inside the object. If it would, it instead set the player onto that side of the object, meaning the player will never actually clip in to it.

This method does have its limitations- but I'm happy with it for now and will update it as I learn more about PyGame capabilities.

Here's the code. Unlike previous projects it does use outside modules and assets, if you'd like those message me and I'll send them over. Otherwise you can watch the attached video to see it working.

[vocal basin]

Damm bro, What engine do you use???

[pine plinth]

pygame

[turbid needle]

pygame and opengl
no one can create a good game by just pygame
u need gpu!

some good games don't even need graphics

u need an artist brain not a gpu+ai

Not Python related but if you had to improve the following logo what would you do?

[mellow flint]

ngl

i read it as "dragon dish"

that K looks very similar to H

[sweet inlet]

💀

I don't really know how to fix that, I'd have to change the font which is part of the logo and finding it wasnt even easy

Is it clearer without the Dragon or no? @mellow flint

[mellow flint]

yep

[sweet inlet]

I also have this one, quite minimalistic imo

[sweet inlet]

Ight

[amber ether]

so basically it's just kind of jittery so i came up with the idea of having a smoothing slider built into my GUI it goes from 0.0 to 1.0 the middle would be 0.50 for example and so i wanted 0 to be equal to the current XHorizontal and YVertical but then closer to 1.0 would be smoother, it's really important that it doesn't just slow it down as speed and precion of these coords is very important, could anyone enlighten me?

def move(self, x, y):
        XHorizontal = int((x - self.screenw) * self.scale)
        YVertical = int((y - self.screenh) * self.scale)

        smooth_x = XHorizontal * self.update_smoothing_factor
        smooth_y = YVertical * self.update_smoothing_factor

        ctypes.windll.user32.mouse_event(
            win32con.MOUSEEVENTF_MOVE, int(smooth_x), int(smooth_y)
        )

[pine smelt]

maybe have 2 separate coordinates the slider, the "real position" and "display position"

and lerp the display position to the real by a some quantity depending on how far it is from where it should be and the distance between either end of the slider

[muted sand]

I finished another class I've been working on! The DrawController uses the player's position and an attribute called bound_dictionary to handle scrolling. It supports an object attribute called "offset multiplier" to determine how quickly or slowly the object scrolls relative to player movement. This is useful for background objects. Then, it uses that information along with the object sprite (determined by the AnimationController) to actually put the object on the screen, using the Draw() method.

hi im looking to make a menu for my game can anyone help?

[muted sand]

😂 I got this name from a Super Mario Galaxy level

[gentle junco]

how do i get my main game program to only be shown when the start game button is pressed?

like how can i hide the game

[limber veldt]

In short, don't draw or update the main game during the time that you don't want to

How you implement that depends on how you're doing it now

[gentle junco]

can you take a look at my code and tell me what way would suit it🙏

[gentle junco]

https://paste.pythondiscord.com/LGNA

[limber veldt]

Maybe make a variable in your main code, call it game_started = False and put your call to drawGameWindow() inside an if game_started: condition. Pressing the 'Start game' button would then need to be able to set game_started = True when you click it

[gentle junco]

ok ok thank you very much

[limber veldt]

Something like so can probably work ```py

somewhere in main, before starting the main loop

game_started = False

in main loop

while True:
# get and process events
# if game is not started, check for 'Start game' button press
# and if pressed, change game_started to True

if game_started:
    # draw and update game
    ...
else:
    # draw and update menu
    ...```

[gentle junco]

thank you

[limber veldt]

No problem. The same kind of logic can be used to run any part of a game but at some point, it gets too messy for me, which is when start defining states for a state machine, but that's another subject entirely

[fathom estuary]

[haughty bolt]

holy shit my game actually work

this is the first time ever

i just need to add sound effect and music to finish it

[low ocean]

Hi guys, currently trying to learn pygame and I created a floor for my game but it doesn't seem to work and I don't understand why

player_gravity += 1
player_rect.y += player_gravity
if player_rect.bottom > 300 : player_rect.bottom == 300
screen.blit(player_surface, player_rect

It doesn't give me any error message but the player just keeps falling despite adding the line of code that creates the floor

[limber veldt]

player_rect.bottom == 300 try = instead of ==

[low ocean]

OMG it worked, thanks

[limber veldt]

Np

[limber veldt]

Nice, working game!

Using the == basically just turns this line if player_rect.bottom > 300 : player_rect.bottom == 300 into if player_rect.bottom > 300 : False or if player_rect.bottom > 300 : True which isn't really an error but doesn't do anything either

[manic totem]

lol

I remember making the same mistake as this guy before

Take me 1 hour to figure out that = and == is not the same

[muted sand]

I got a prototype for my first game working! https://youtu.be/B4BOlfwmm2k?si=Mk7HgQbtaL-ddhtT

[bold hill]

May I ask a question

How can I make interactable objects in pie game sorry

[raven kernel]

3.14 game?

[vagrant saddle]

a simple examples here https://github.com/pygame-examples/pygame-examples/tree/main/pgex/examples/buttons

[raven kernel]

you might want to look into the pygame.sprite API

[vagrant saddle]

and for moving objects what Axis said

[raven kernel]

you'll have to make te interactability yourself though

[bold hill]

How long does it take gifts sorry

[bold hill]

this is why im asking @vagrant saddle my apoliges

[raven kernel]

what are we seeing

[bold hill]

It's supposed to be the power core and maybe she'll generator for part of my game so that's why I was wondering so if the player if I have to add a text box with manual typing inputs I want to play an animation to turn on and turn off the core sorry

[vagrant saddle]

if you want user interface interactions when you want to see pygame_gui examples

eg https://pmp-p.ddns.net/pygbag/help/LiorTM/l3mur27-liortm/build/web/

[bold hill]

Thank you I seen for buttons anime file for running the main game thank you

[bold hill]

Does any tile that I make for a part of the world supposed to be a bitmap? Sorry

[limber veldt]

Image, surface, bitmap, choose a name, they all mean basically the same thing within the context of displaying images on the screen

And can you drop the 'sorry` with every message, it makes me feel like you've already done something wrong

There is absolutely nothing wrong with asking questions here

[graceful yew]

a question on organizing code: is it "better" to have a sprite that also contains data not related to rendering or keep the sprite separated from the entity that it represents? this is for pygame, if it matters

[limber veldt]

I usually keep all behavior for a sprite within the sprite itself (actually a subclass of pygame.sprite.Sprite) and add it to a pygame.sprite.Group() to handle the rendering and updating, the group can draw/update all sprites within it inside my main draw() and update() methods

[agile finch]

hey guys, I have a problem related to object rendering. i copied the code from a tutorial, this one to be more specific https://www.youtube.com/watch?v=PsBYRAYVr5Q&list=PLn3eTxaOtL2PDnEVNwOgZFm5xYPr4dUoR&index=7&ab_channel=GetIntoGameDev
and now I am trying to load a bigger obj file (Vertex count: 2083581, Total faces: 694527, Total edges: 927913) but nothing appears in the pygame window
but from my console debuging i can see that the object was read and loaded. what do you think i should do?

[bold hill]

I am sorry I did pixel art because I couldn't sleep and I exported some of them as a gift that can play an animation like the one above no I would have to convert that into a bitmap?

[vagrant saddle]

animations are sequences of bitmaps, usually stored as tiles horizonally or vertically in a single file eg https://pygame-web.github.io/showroom/pypad_git.html?cpython3.12#src/test_anim.py

here's the tiles used

[bold hill]

Thank you

So I have to convert it to a bitmap.

[limber veldt]

That's a cool game of life filler pattern

It eventually reaches steady state in a mess though, since I have it wrapping around

175x200 grid size

Reference https://conwaylife.com/wiki/Spacefiller

[bold hill]

Do I need anything specific to use a bitmap?

[limber veldt]

Interesting, I haven't tried anything like that
