[lost geyser]

is godot engine planning to add python to it?

[normal silo]

It supports every programming language but that version is not officially out yet.

[lost geyser]

oh it does?

[normal silo]

When it's out you can simply download the python support someone added from the asset library (directly in the godot editor): https://github.com/touilleMan/godot-python

[lost geyser]

ooooh, thnx

gonna try it out later

[glad oak]

can I make 3d games in python

I know I can make 2d games with pygame

[glad oak]

someone told me about blender

I know how to use blender

but I don't know how to create a game in it

[potent ice]

@glad oak you could check out Ursina

[glad oak]

I check that but that's not what I want

[potent ice]

Then you should be a lot more specific

There used to be a game engine for blender

This is now a separate project : https://upbge.org/

@glad oak I assumed you were looking for something related to python since you are asking the question on a python server. If none of these fits what you are looking for you need to be more specific.

[glad oak]

ya I heard that

but accually I want to make a python server for my unity game

because of python libararies like tensorflow

[errant stone]

Can you recommend pygame course(video or text format, both are fine)?

Hey @meager fable!

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

Hey!
Anyone here who is willing to contribute to this open source module? https://www.reddit.com/r/Python/comments/my47xe/pyunity_a_python_implementation_of_the_unityengine/

[meager fable]

Checked it out and it looks really good, I'm not a really good coder so I can't help out much but I'm definitely going to follow its progress. you should try posting this in other coding discord servers as well, might grab someone's attention

[main blade]

Yea. I am posting in many servers. We also have a discord server, if u wanna join (pls tell me if this is known as self advertising I'mma delete it)

[meager fable]

I'm good, appreciate the offer though! not sure if its classed as advertising might wanna check with the mods

[main blade]

Yup. That's why I included the bracket

how do i implement the a* search algorithm for search finding in pygame, because its not tile based

[wind torrent]

Make your game tile based I'd say 😀

[tiny peak]

hello..?

[tawny crystal]

hello

can we make a game with optional mods in pygame?

like a specific file extension that can open and load a mod in my game?

[faint berry]

Pygame doesn't have anything like that so, you should make ot from scratch.

[tawny crystal]

Ohh alright

[uneven eagle]

imo arcade is a better library

[west stag]

Does anyone know what is the main programming language used to create a DNS?

HOW TO MAKE A GUI

[elder ginkgo]

Use tkinter or pygame

[rough vigil]

Tkinter is boring

Pygame whts tht

[fading whale]

It's a library for developing 2d games with python. But you could also use it to create a GUI.

[wheat moth]

Quick Noob Question Alert:
Essentially, I want to randomly generate a set of four ability scores.

I have written a function that does this.

When I set the variable
mystats = generateStats()

every time I run this, mystats is overwritten with the newly generated stats.

is there a better way of making that rolled set persistent?

Ex: would savedStats = mystats.copy()
make a copy of the stats that were rolled and ensure it isn't overwritten? Or will it still be overwritten every time?

Or...is it better to export those stats...to a file perhaps, that can be read later to grab said stats when needed?

I considered, an alternative of a lambda that runs only when called...I think thats how they work....

[craggy rain]

Hey guys I wanted to ask a general question so sorry if the scope is kinda broad. I am trying to make a simple platformer with a friend and have some python knowledge under my belt and have been using pygame to create my idea. I have been using tutorials which I feel kinda guilty about since I feel like im "cheating" or something and feel like I should be able to figure it out myself even though ive never done this before. I dont want to make tutorials my crutch and be self dependent but dont know how to go about it? Also to make games is it better to simply throw myself into a new language such as C# with Unity or use python so that way I can use it for all types of projects such as web scraping and other things. I just feel unsure and thought someone whos done this before me would have advice. If you have read this far thanks for the time and sorry itsvery long! 😃

[finite briar]

The best way I've found is to watch a few tutorials when you're first entering a subject and then if you have a more specific question you look it up; avoiding tutorials is fine as well

[craggy rain]

Yeah that sounds good too, for me with this platformer I found a series but I never know how heavily to rely on it because sometimes I feel like im not learning but rather like just grabbing pieces of it. I think trying to do more independent stuff might be smart like you said a few tutorials and then specific questions later. Like for a platformer look up like tilemaps and movement or what basic videos would you think?

[finite briar]

Coding with Russ is a channel that i watched, it helped me understand the basics easier but as i said a lot of this stuff its just soooooo much better to learn individually; but tutorials for general knowledge and new topics yeah

[next estuary]

I'm working on a snow-themed game, I want to add spider-man style swinging with some elasticity but I'm not sure what to search for math wise. If anybody has a good module / guide I'd appreciate it.

for learning individually you mean like on your own or like individual piece by piece of a project? but yeah new topics fs

[dawn jolt]

i've tried using kivy before to make a lightweight graphical project

but after compiling it, the resulting program took a lot of space

is this specific to kivy only? should i try a different framework?

or is it because of how python runs things

[dawn quiver]

how do i make an entity spawn only if its chosen, and it would be chosen at random from a list

[fervent mesa]

@dawn jolt If you want to make a GUI application that has a modern GUI I would recommend PyQt5 because of its style that can be changed using CSS, if you want to make a simple GUI application I would recommend Tkinter if you want a simpler version of Tkinter you can use PySimpleGUI, let's just say PySimpleGUI is a simplified Tkinter

PySimpleGUI docs : https://pysimplegui.readthedocs.io/en/latest/

[dawn jolt]

can i use it for game development?

specifically where i need to compile it

[fervent mesa]

for that I don't really know, because I usually create a GUI in games using pygame itself.

in the pysimplegui repository they gave an example of making pong games using pysimplegui

https://github.com/PySimpleGUI/PySimpleGUI/blob/master/DemoPrograms/Demo_Pong.py

[trim nacelle]

I pip installed pygame and it seem to work but it's giving me this error

[potent ice]

Maybe py and python use different python versions?

just run the script with python and see if it works

[trim nacelle]

that might be it

let me try it

[potent ice]

maybe?```
py --version
python --version

[trim nacelle]

yea they're different

aight thanks for the help

that was a rookie mistake

[potent ice]

No worries. pip can also be a source of confusion so it's also safer to run it through the same python command python -m pip install <package>

[trim nacelle]

yup

will do

so I'm looking at this sorting algorithm visualizer that I found on github

https://github.com/fraserlove/python-algorithms-and-simulations/tree/master/sorting-algorithms-and-visualisers/sorting-visualiser

It gives a white screen instead of what it's supposed to do

[errant stone]

is it better to use rectangle or sprite for gui in pygame?

[red oyster]

Ok friend

[wispy lily]

@dawn jolt could you please tell me what this tool is?

[dawn jolt]

oh wait you're not using linux?

you've probably looked at buildozer right?

[wispy lily]

yes

[dawn jolt]

haven't really tried it

but that's what i'm referring to

sorry to get your hopes up

buildozer only works on linux unfortunately...

Guys how do i add a 'glow' to my sprites in pygame 🤔

ive seen youtubers do it for their games in unity

[dawn quiver]

am working on a new game 😊

its going to be a maze game

the lighter shade of tiles are indistrcutable

and the darker shade are breakable by shooting

:D

am going to make it such that the map moves with the player

so like

instead of players position increasing

i will just append more tiles to the map while deleting few

so for example if he moves to the right

world_data.remove(left column)
world_data.append(new_right_column)

O.o

wow

The rotation is a bit

shaky

how to fix?

[dawn quiver]

you can make an invisible line, and see if it collides with something

[sinful hearth]

i already found a better solution: pygame.sprite.Rect.clipline

[dawn quiver]

just blit the line based on where the user is facing

[dawn quiver]

oh i see

[dawn quiver]

so

can u

uh

help me

[dawn quiver]

.

[sinful hearth]

ok?

i'll have a look at it

[sinful hearth]

you didn't include any of the assets in the website, so i can't run your game

[dawn quiver]

i just wanted u to spot any obvious errors

i mean

i can give the assets and all

but do u really want to run it

[sinful hearth]

i can't really spot any errors from just looking at the code

[dawn quiver]

ok then nvm

ill just

try fixing it

with stackoverflow

[sinful hearth]

maybe instead of repeatably rotating the same image, try just rerotating the same image

maybe that will fix any loss in precision?

[dawn quiver]

that reduces the quality with every frame

which is what causes it to crash

[sinful hearth]

so you already aren't doing that

ok

i don't think i can help you because i am short on time rn

[dawn quiver]

ok

have a nice day

I figuered it out.

I didnt have a centered image lol.

guys i set up Pycharm but i don't know anything about python and i want to make a multiplayer 3d game so i heared about ursina engine but don't know how to set up it so now any help lol thx for reading !

[pale compass]

Learn basic Python before you attempt to create a 3D game.

[quiet crane]

I just got the mission game book thru humble bundle, and I'm in the beginning where you set up the background and stuff. For some reason, even when I use the exact code as written in the book, my pygame window has a chunk of blackspace that cuts off the picture(s). Anyone worked with this book and know what I am talking about?

[quiet crane]

Escape game*, misremembered the name

[normal silo]

Due to the way pygame renders things (via surfaces), the rotation function resizes the surface causing a shifting center. When it blits the image the center is rounded and since it's constantly changing it wobbles a bit. Fixing this stuff is annoying and pygame is really weird so I would recommend just using arcade instead.

[dawn quiver]

i actually just ended up making it a feature lmao

by adding the same wobble as idle animation haha

but the idle wobble is up and down

[normal silo]

Arcade does not have this issue because it renders with opengl which does not do this whole surface thing with resizing while rotating, in general it will save you headaches by switching to it (also, speed). @dawn quiver

[dawn quiver]

or i could just use opengl

lmao

yes :P

[plush forge]

ok

[harsh yoke]

i need help

iss cool you can go first

i use a udemy course for the python part and brilliant for my animation

in game dev obviously

i see

hmm

yes python isnt in any games ive seen so this is rare...

i would take a udemy course

they have courses for all aspects of a game

but ususally only some parts are used for a game

because like it is only python is rare

yes

its 189 usd but well worth it in my opinion

think it was 24 during last week

but it updated

ah

https://pythondiscord.com/resources/tools/

?

maybe theres course info in the tools/refrences

hmm

[frozen knoll]

@dawn quiver See https://learn.arcade.academy and https://arcade.academy

[tawny crystal]

I'm not the only one that uses arcade :D

oh wait

[dawn quiver]

thanks mate

        world_data.pop()
        print(world_data)

[tawny crystal]

Should I use Pygame or arcade?

[potent ice]

Are you fairly new to python?

.. and what are you hoping to make?

[tawny crystal]

Yeah I am.

Hi i rly need help with my game. I Have made a Menu and a Game but the button that says start I need it to start the game. Same with the exit button I need that to close down the game.

[limber veldt]

More context needed. Like what are you using to draw your game and buttons?

I'm trying to make a Defender game (classic arcade game), and struggling with the wrapping

I have a surface than I'm scrolling through with a viewport and I want it to wrap smoothly from right to left or left to right. But that transition from one end to the other is not smooth

So I think I need to copy my surface and have two of them in a row

So at the end of the first surface is the start of the same surface and the jump back to the actual start will be smooth

I really don't even need the second surface to be a complete copy of the first, only the first SCREEN_WIDTH pixels of it

Same on both ends, I suppose. A copy of SCREEN_WIDTH pixels from the right placed on the left and from the left placed on the right

Pretty new to this kind of thing, coding a viewport and using multiple surfaces

[marble flame]

Any experienced MOD, with super coding skills? DM me immediately

[frozen brook]

Hi, I just fixed a error in my very basic code. I was hoping anyone could explain why the error occured.

I got a "video is not initialized" error, and the fix to that was to move "pygame.quit()" from the while loop into the if statement (in the same loop).

Code: https://pastebin.com/VrhVPHdc

Dont mind me, I just realized how stupid I am 😄

[sinful lodge]

put pygame.quit outside the while RUN

[dawn quiver]

What would you have said if he said no and 2d game?

[limber veldt]

Infinite circular scrolling and player movement pretty well worked out, I'm learning! https://pasteall.org/d4Qr

Next, I gotta dig into pygame sprites

How to add sprites to lists and use the collisions

Pretty hacky way to do the minimap but it works. Just triple it, all three side by side, then scroll it using the offset and use two black rects to cover the parts outside of the minimap

Actually, the same kind of trick is used for the main screen to get it to wrap nicely too

Scale the actual playing field, 9720x512 pixels, to 480x88, put three of them side by side, and scroll it properly = minimap

No drawing blips or translating or converting, just scale the entire surface

I'm not pleased with the mismatched aspect ratios of main player screen and minimap, but from what I could tell, that was pretty close to the original

[potent ice]

You'll have a lot more options. pygame, acrade, pyglet, cocos, wasabi2d .. and the list goes on

Even ursina/panda3d

The reason I recommend arcade to beginners is that it's a project created for learning and has a lot of official examples and tutorials including a book

[modest crow]

I am trying to do something stupid.
I am doing this to get the keys

keys = pygame.key.get_pressed()
ball.update(keys)

So how do i type hint in the definition of update method?

[past star]

where can i ask questions i am a beginner

[modest crow]

look in the help channel if it is about a specific thing

look in to #❓｜how-to-get-help

[past star]

and can i ask if creating games need gpu??

[modest crow]

if you read it you'll get an better idea what can be asked

which is almost everything

[modest crow]

it depends

[past star]

bc i can not buy a gpu it"'s expensive

[modest crow]

what games are you making?
if you are makings game with python. you won't need it most of the time

[past star]

ohhhhh

[modest crow]

it depends more on the game

[past star]

i am working on a big big idea bro i think i'll go viral bc of it

i am a creative person but now i just started learning python language and how to use it in spyder ide

[modest crow]

can you program well?
if not just get started, right now.

[past star]

i use to work on small basic\

[modest crow]

yes, solidify your basics, learn a new language. then you'll get a grip of programming

then start with your project

[past star]

i am a 14 years man so have along way

thx man for your support and help

[modest crow]

It won't mean anything if you don't start though.
so just keep going

check out

[past star]

thx man but can i ask one more question about which course or where did you train or study python

ahhhhhhhhhhhhhhhhhhhhhhhhhh

thx buddddyyy

which ide you use?

[modest crow]

you don't need to buy courses though, youtube is great, the internet is endless, guys here help out

[modest crow]

IDE doesn't matter

i use neovim, not an IDE just a text editor

[past star]

it'smore organized

you use pthon on nevoim?

[modest crow]

sure it is, but how long is your code going to be to need a tools which are tightly integrated, which are made for large code bases

[modest crow]

python is an interpreter, neovim is a text editor

[past star]

games need a lot of large codes

[modest crow]

yes.

I am not saying that IDE's aren't for small code bases, but they get in the way

[past star]

and character designerfor games and these stuff which software i use?

[modest crow]

what type of game are you thinking?
3d, 2d, board game

[limber veldt]

Fusion360, Blender

[modest crow]

FUSION360???

[past star]

if you know a game named curse of aros

or growtpia

growtopia*

[modest crow]

just ducked them

[limber veldt]

Yes, Fusion360

[modest crow]

Isn't it for engineering models?

[limber veldt]

Models of any kind

[modest crow]

dad, those games look like they are 2DD

[past star]

yeah i think so

[modest crow]

Okay, i didn't expect that out of fusion360

[modest crow]

you can use gimp

[past star]

my pc is under construction so i am using now window 7 it works on it?

[modest crow]

sure any thing which works

[past star]

omg thx everybody

[modest crow]

just don't forget to start programming.

[limber veldt]

Character design for games will usually mean 3d characters even if used in a 2d game

[modest crow]

and @past star please don't use sypder

[past star]

i am hopping into youtube to check a bald man teaching python

[modest crow]

those games looked like sprite art ones

[past star]

what should i use remind me

[modest crow]

start with vscode

it is very popular

or sublime, it is simple and FAST

[past star]

this summer i'll end up gettting a job even if i am 15 ill work harder to full the bg

bag*

[limber veldt]

Like I'm making a 2d game now, and have made others, where I used 3d models (for proper lighting) and rendered them to sprite sheets

[past star]

how mant games have you created

[limber veldt]

Hmm, maybe a couple dozen

[past star]

what isdozen?

[limber veldt]

Dozen = 12

[past star]

twelve

ahh

[limber veldt]

So maybe 20-30 games

[past star]

i just check it

i wanna play one

i am on android

[limber veldt]

I've been hobby coding for years

Some projects aren't games, others are

[past star]

have you uploaded a game n playstore?

[modest crow]

are they online somewhere i can take a look?

[limber veldt]

Nah, just some Python games for the past few years

Some I made in Blender

Blender used to have a game engine built in

And was pretty good engine

[modest crow]

[limber veldt]

Still is but it's no longer a builtin, it's an addon

[past star]

have you created one?

[modest crow]

i have made maybe one or two, i am not as much of game maker

[limber veldt]

Most of my games are simple, like Tic Tac Toe, some more complicated like Cribbage (a board game with cards), some are shooters like Asteroids, some are pong-ish like Arkanoid. Now working on another classic arcade game, Defender

[modest crow]

cool

BTW, learning blender is a single arrow, and a whole bush of birds

[limber veldt]

Some are very complex, like Rubik's cube animator/solver

Blender doesn't have a learning curve, it has a learning mountain

But it's unmatched in 3D modeling

[modest crow]

like this?

[limber veldt]

Like there are other modelers out there, they cost an arm and a leg, and they're really not any better than Blender

[past star]

but guys i can't start coding if i didn't get morenowledge so i don't think a 6 hours course will help

[modest crow]

don't think

just go with a youtube video you like about a topic

like search for "make a game in python"

then they will mention something you don't know about

like functions, then search for "functions in python"

then keep going like this

if stuck ask here

i mean look here #❓｜how-to-get-help

[limber veldt]

Defender progress so far, you'll need pygame installed, use the arrow keys to for movement: https://pasteall.org/fNEe

[past star]

umm guys if i am coding and i wanna see if it worked or check the game without upload it and reinstallet

[limber veldt]

Game mechanics pretty much done, now to add sprites and collisions and firing bullets and enemy types and humans to rescue and ground and...a lot

[modest crow]

What do you mean?

[limber veldt]

The enemy behaviors are scaring me, coding AI behaviors is tough

[past star]

it's like i just put a new item in the game i wanna see if the item is actually in the game that i am coding

[modest crow]

You can just run the game

[limber veldt]

You code on a computer that can run the things you make

[modest crow]

As i said, you need to start. Questions will form, answers will come

[past star]

thx a lot you're good guys

[limber veldt]

The AI behaviors here: https://youtu.be/gss3lxeqCok?t=424

[modest crow]

You doing this in python?

[limber veldt]

Yes

Got the mechanics worked out for how things move

It should be fairly easy-ish to complete

Just take it one bit at a time

Mine probably won't be exactly like that, but a reasonable facsimile

[past star]

ayo bro

sublime

needs pythonto be installed

or what

i needto know better about these little stuuf

stuuf*

[limber veldt]

I haven't used Sublime but perhaps it's like those I have used. It might ask you during the installation to point it at your Python installation so knows what interpreter to use

So yeah, I'd install Python first

[past star]

i installed python

[limber veldt]

Good

[past star]

thx buddy

[limber veldt]

And you should, during that installation, be sure to enable the python to path thing

There's a tickbox for that in the Python installer

That way your whole system points at your python installation when it encounters a python program

[past star]

should i use the newest python version?

[limber veldt]

Yes, unless you have some specific reason to use an old version, always install the latest

I don't think it's totally necessary to download the latest every time there is a release, but you always want to be within a few months of the latest version

[past star]

window 7 require the 3.8

[limber veldt]

That might be an issue for you, yeah

Windows 7 is a problem, it's not even fully supported anymore, end of life

[limber veldt]

Windows 7 is that specific reason I mentioned there

Or one of them

[modest crow]

Just use the latest you can use.
And never use python 2

[limber veldt]

Added player blip to the minimap, progress!

[dawn quiver]

so like

every time i feel like quitting my game

i end up reading a game dev chat

and feel like doing it again

;/

ima properly stop now

[limber veldt]

You can do it

[past star]

bro do not stop what you have been strated

[limber veldt]

Did you check out my progress so far? I like it!

[past star]

you can do it

[limber veldt]

What doesn't kill you makes you stronger, especially when it comes to tough codes

[past star]

the future is wating for you

you need to full the bag

money is the best thing existed

without money you cannot do anything lol

[rustic plover]

what game should make to train

[limber veldt]

Asteroids

[past star]

tic tak toe

[limber veldt]

That's another good one, depends on level. Tic tac toe for beginner-ish level, Asteroids for intermediate-ish level

[past star]

is tic tac toe easy?

[limber veldt]

Asteroids is good because rocks don't need AI

[past star]

or theres alot of typing?

[rustic plover]

i made a game wghere you have to avoid cars

[limber veldt]

Sound advice

Like frogger?

[rustic plover]

but it was mostly word for word from the tutorial and by the end i ctrl c ctrl v the entire code cuz it didint work

[rustic plover]

eeeeeh

[dawn quiver]

Nono, thats not the problem, im saying im bored of it lol

the game im working on isnt very fun

[limber veldt]

That's ok, having the interest to even copy and paste should motivate you to try learning from it and in that regard, it's ok to copy and paste, just make sure to learn from it!

[dawn quiver]

ill just work on a differnt game

actually

[rustic plover]

k

[dawn quiver]

im just

gonna revise my web automation

start ML

and continue my web dev

i find those more fun

[rustic plover]

i think that tic tac toe would be too hard

i could use tkinter for dat

[dawn quiver]

thats

not good

theres no point

[limber veldt]

Tic tac toe can be done with a UI in less than 150 lines

[dawn quiver]

and dont say you made it

because its not your code and theirs nothing original about it

you need to read the docs, or pick up an article, or use tutorials only for certain concepts

theres no point if you watch the tutorial for the entire game

[rustic plover]

well how am i supposed learn pygame if i didnt know anything about it

[dawn quiver]

first understand how the fuck something works before making a car game

understand how a jump works

watch a video on it

then try doing it

or just think for 2 min

[limber veldt]

That's exactly how but just make note of that when you tell people that you made a game

[rustic plover]

chill dude

[dawn quiver]

"Hm.. so now that i have a window open... how would something move on it?"

Then you will learn to blit an image to the screen with google

[limber veldt]

I usually credit those I get ideas from

[dawn quiver]

then you will use ur brains to move the image on command with keypress

and slowly

you will make your way to bigger projects

[rustic plover]

im just gonna stick to discord.py or other stuff

[dawn quiver]

well

thats your choice

[limber veldt]

Like you learn how to do something by seeing how it's done. The learning part comes when you can actually do it yourself and understand the concept and can do it without looking up how it's done

I still have to look up a lot of how it's done, because people have worked out these things and I don't yet know them, like methods of a module. I have to look up everything with pygame methods at least a couple of times

Because I don't know it yet

But I know the concepts since I've been making games for a long time

Wanna see my tic tac toe code?

It's one of those games that's a lot easier than many would think. All 'innings' are the same...one player places an X, the other player places the opposite of X. After each turn, check for win in rows, columns, diagonals, or a tie, repeat

And it's a good intro project for OOP and using a class

Making each of the grid squares into objects with attributes and methods, like how to draw themselves and what to draw

The entire class for grid squares (Spots) in my tic tac toe...```py
class Spot:
def init(self, x, y):
'''
Spot objects will be drawn to the screen at the cartesian coordinates of self.x and self.y.
Reads global constants to determine size and where to draw self relative to self.x and self.y
'''
self.x = x
self.y = y
self.value = None # used to determine whether self is an X or an O or nothing

def show(self):
    if self.value == None:
        pygame.draw.rect(screen, WHITE, [self.x*wr, self.y*hr, wr, hr])
        pygame.draw.rect(screen, BLACK, [self.x*wr, self.y*hr, wr, hr], 2)
    elif self.value:
        pygame.draw.line(screen, RED, [self.x*wr+20, self.y*hr+20], [self.x*wr + wr-20, self.y*hr + hr-20], int(width/30))
        pygame.draw.line(screen, RED, [self.x*wr+20, self.y*hr + hr-20], [self.x*wr + wr-20, self.y*hr+20], int(width/30))
    else:
        pygame.draw.circle(screen, BLUE, [self.x*wr+wr/2, self.y*hr+hr/2], hr/2-20, int(width/30))

[past star]

let me chgeck you tictactoe

[limber veldt]

https://pasteall.org/A4Lt

So I use the Spot object's .value attribute to determine if the square is empty (None), or an X (True) or an O (False)

And note when I check for wins. Not once in that code do I check if something is an X or an O, all I care about is if they form a row/column/or diagonal of equal values

One side-note, and the row/column or diagonal doesn't have a None in it

Equal but not None

[past star]

the code is notbuilding

[limber veldt]

Not building?

[past star]

they tell me this

[limber veldt]

That's weird

There's nothing VSC specific about it and it loads nothing

Beyond imprting pygame and sys

But I just copied and pasted it into VSC and it is messed up, let me try the other paste site...

!paste

[frank field]

Pasting large amounts of code

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

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

[past star]

i ll use another ide

[limber veldt]

Yeah, that's weird. I'm getting some unwanted characters from both sites, pasteall and hastebin

​

​

Yeah, it's an escape character

Never saw that happen before either so not sure why there are escapes on every empty line in VSC when copied from one of the pastes sites

Ok, so that might be happening to all the codes I've been posting

On those sites

And I don't know why

Well, they're easy to remove by selecting one of the bad lines (double click it) then select all occurences and backspace them

But still don't know why they happen

Until I do know, I'll stop using them

[past star]

i just started caculating by coding

i am getting better omg i am happy

Snow themed game I'm working on, I was hoping to make the game snowier but it starts to lag having that many entities loaded, I was wondering if anyone knew of a blender rendering trick to prerender a bunch of entities in a 3D space for use in a game

[dawn quiver]

did u use panda3d ?

@next estuary

[next estuary]

Ursina

What's panda3d?

[dawn quiver]

bro it's insane

[dawn quiver]

it's a motor for video games on python

bro u are incredible juste wow

[next estuary]

Ahh, I don't want to rewrite it in a 5th engine heh I already did it in pygame in 2D and got the snow rendering in 3D OpenGL
(OpenGL demo below)

I played with a few others too but Ursina was really user friendly

[dawn quiver]

i just know the bases of python, is it easy to learn ?

[next estuary]

https://youtu.be/uUc370bLUJo
Pygame

Yeah python is one of the easiest languages to learn in my opinion.

[dawn quiver]

i'm not bad in pygame tooo

[dawn quiver]

is it ur creation ?

[next estuary]

The game is, I haven't written any engines myself. That one is written in pygame but pygame is pretty slow

[dawn quiver]

wow i watched the teaser of Ursina, it looks good

[next estuary]

It's an awesome engine

I'd recommend it for any beginner wanting to make a 3d game

It has preset control schemes for fps, racing, and other genres

A bunch of included models and textures

And it's pretty fast for being python

[dawn quiver]

okay

can i just ask u ur help

i have a problem with classes

look :

for the moment, i just write the script for the mooves of mario, here, my classes :
class mario :

def __init__ (self) :
    self.Mario_jump_left = mario_saut_gauche (fenetre, Mario__saut__gauche,y,x)
    self.Mario_jump_right = mario_saut_droite (fenetre, Mario__saut__droit,y,x)
    self.Mario_normal_right = mario_normal (fenetre, Mario__normal__droite,y,x)
    self.Mario_normal_right = mario_normal (fenetre, Mario__normal__gauche,y,x)

and when i start the script, the events don't work (the d key for go to right, the q key to go to left and the key z to jump)

so i decided to just forget the classes and i just done the functions without classes

and it works

but i just want to know why when i use the classes, the game does not work (tell me if i did error in the class)

I know taht classes are really important so i really want to know what's my error

[next estuary]

Can you post the full code on github? I can't see the issue here

[dawn quiver]

yes but i'm french so the functions are in french 😅

i will send u the code with the classes

[trim current]

Hey everyone, im a Computer Science student and I am looking into entering game development when I graduate. I know this is a python server but which languages do you guys recommend to start learning for making games?

[next estuary]

Python

Ursina, Pygame, or OpenGL for the engine

[trim current]

Ill give it a try thanks man

[frozen knoll]

Don't forget Arcade as an option. Lots of examples: https://arcade.academy

[sly sun]

hi

[next estuary]

I'd never heard of arcade

That's super cool

I love the cave generation example that's cool, I'm gonna write a blender plugin that does that to make 3D mazes

[trim current]

I saw that pygame 2 is out, should i try that instead?

[distant kindle]

what app do you need for python

I'm a beginner🤔

[frozen knoll]

For game development? Might look at https://learn.arcade.academy to step you through it.

[formal fable]

hey guys i made a .exe game file check it out please

[frank field]

Hey @formal fable!

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

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

[formal fable]

ok

[dawn quiver]

i think you could use if statements

[modest crow]

You shouldn't post executables anywhere, not just here.

I would say

[idle falcon]

Does anyone know how to use pyopengl?

[midnight heart]

What is the best python game engine?

[midnight heart]

what is it?

[idle falcon]

If your talking about what pyopengl is, it’s an OpenGL wrapper for python. In the case of your question, I think organelle is the easiest to get started with but pyglet is also pretty good

[midnight heart]

what is an open gl?

sorry i'm a beginner 😅

what is better pygame or python arcade library?

[nocturne vale]

wich game engine is the best for python?

[idle falcon]

i think pygame is better

just my personal opinion

[nocturne vale]

ok

what is better godot 3 or pygame

[modest crow]

pygame for learning, godot for real projects

tho they are different things

[nocturne vale]

ok thanks

[modest crow]

start with learning python, THEN do what you want

[idle falcon]

also, godot has a completely different langauge built in so you'll have to learn that as well

[frozen knoll]

@midnight heart if you are starting out, you might want to look at https://learn.arcade.academy

[midnight heart]

ok thank you

[midnight heart]

but can i program in python with pygame on godot?

or with arcade librery

[modest crow]

Nope

You don't need to

Learn what is needed for making a game with pygame.
Then, if restricted by it, venture for godot

[midnight heart]

ok thank U

[modest crow]

👍

[candid smelt]

Hello freinds,
i was trying pygame for game devopment,
so i installed it in my mac and it installed perfectly,
but when i tried to make a pygame window with an image,
this happened,

why the heck is this distorted

pls help

[limber veldt]

How about in here...see the ground in this image? I'm really struggling to come up with a procedure to add random 'hills' to it

Maybe I pick a random pixel of that ground and elevate it some random height then pull those up next to it until it forms a hill

[limber veldt]

Oh that's really hard to work out since I don't want to make hills where there is already a hill

[limber veldt]

Hah, I kinda did it...

With this ```py
ground_group = pygame.sprite.Group()
x = 0
y = 1
while x < 9720:
g = GroundPixel(x, 580.0 + y)
ground_group.add(g)
x += 3
r = random.randint(0, 100)
if r == 0:
new_y = y
height = random.randint(0, 150) + 20
for j in range(height):
if j < height / 2:
new_y += 2
else:
new_y -= 2
g = GroundPixel(x, 580.0 - new_y)
ground_group.add(g)
x += 3
else:
y = -y

It's not quite the same alg as the original's ground maker but close

The original could do nested hills

[clear crane]

How do I start to code a py.game

[limber veldt]

Well, I can share with you my version of tic tac toe, written in pygame, maaybe you can work through some of that

[limber veldt]

Really simple game, the setup is pretty straight forward as most pygames start the same way: https://pasteall.org/2khe

After that, you look for Tech with Tim on youtube, he has a vast collection on PyGame

[clear crane]

I started this video, and he made a window

Im trying to press the arrow in pycharm to open the window and it wont work

[limber veldt]

Is there an error message?

[clear crane]

No

`import pygame, time

pygame.init()
window = pygame.display.set_mode((600,300))
myfont = pygame.font.SysFont("Arial", 60)
label = myfont.render("Hello Cole" , 1, (255,255,0))
window.blit(label, (100,100))
pygame.display.update()
time.sleep(5)
pygame.quit()`

@limber veldt thats all it is

and it wont let me play it

Do I maybe have to add a configuration

[dawn quiver]

That looks really fun to play, were you aiming for a retro look? If so you did an amazing job.

[sinful lodge]

wait

are u saying that the pygame window aint opening?

u need to use pygame.event.get()

[scenic girder]

Hello! I'm looking at this piece of code

gl.glTexImage2D( gl.GL_TEXTURE_2D, 0, gl.GL_RGBA32F,
                         self._data.shape[1], self._data.shape[0], 0,
                         gl.GL_RGBA, gl.GL_FLOAT, self._data )

self._data is a numpy 3d array(created with np.zeros). how do opengl convert it to void* on the go? does it just take [i][j][k]?

this is a python thing, if I'd done the same thing in another language it would either crash or wouldnt compile

are n-dimensional arrays in python contiguous?

[proper peak]

Yes (and I'm not sure what non-contigious implementation you have in mind - I thought contiguous was the normal way to implement n-dim arrays)

For a description of how they work, see Anatomy of an Array here:
https://www.labri.fr/perso/nrougier/from-python-to-numpy/
(and in general it's a very nice guide to numpy)

[scenic girder]

@proper peak normally in c/java etc. an n dim array is an array of arrays. That was ehat I thought, but numpy handles it differently.

[lime ether]

not in c

[scenic girder]

?

a 2d array in cc int** arr = malloc(5 * sizeof(int*)); for(int i = 0; i < 5; i++) { arr[i] = malloc(5 * sizeof(int)); }

a 2d array = an array of pointers = a pointer to pointers

[lime ether]

that's an array of arrays

if you don't do that, it would be contiguous

like int arr[3][3][2];

[scenic girder]

Hmmm, honestly I never used multi dimensional fixed size arrays. Thank you :)

[next estuary]

@limber veldt have you tried perlin noise?

It's pretty good for procedurally generating terrain

[limber veldt]

Hey thanks, it's getting there and yeah, retro...the original was made in 1981

[limber veldt]

Thanks for the suggestion but no, it's just 2d line for my 'ground'

If I were to do a procedural 3d ground, I'd probably whip up a noise texture to use as a displacement map

[clear crane]

Hello, I have just started pygame and made a window opener. What do I do next, because I want to make a starter game.

[limber veldt]

Tic tac toe is a good starter project, I think

It'll get you working on breaking down the logic and program flow

Asteroids or some kind of block breaking game also good starter project but maybe not good firstt projects

And, if you can, do the tic tac toe without looking for someone else's code for it

We all know how the game works already

[clear crane]

Ok, ill try that but can I ask how do you make a grid

3x3

[limber veldt]

Well, maybe what you do is make one square with a border around it then make eight more the same way, arange them on the screen and viola, grid

Another important part is getting mouse clicks or keyboard presses

And where mouse clicked, even more important

Because if we know where the click happened, we can do some pretty basic maths to know where on the board was clicked

And which grid square

If just starting with Python too, I'd suggest a functional code but if you know any python at all already, it might be time to dive into object oriented programming, OOL

Tell ya this, tic tac toe or any kind of grid game or game in general really benefits from being object oriented

Think of classes as object factories, once you know how to use them, they're very powerful

Stuff like this probably not even possible without classes: https://imgur.com/gallery/2uqVNjA

In that code, all those grid squares are separate objects. Each has a color at the start, and has attributes for which walls are True (yes, wall there) and whcih walls are False

And just a bunch of logic to generate and solve a random maze as fast as I could make it happen

The purpose of that project though was not to practice maze solving but to learn path finding algs, very applicable to games

[heady pine]

is it ursina or pandas3d? although ursina is based on pandas, but i dont know if they use the same debug window

[quiet grail]

IM BORED, any game suggestions?

anything?

[heady pine]

4 dimensional game

[next estuary]

@heady pine Ursina, I really love working with this engine

This is what I'm making with it currently

[limber veldt]

Hah, look at that, completely recreated the enemy explosion

On the right, the enemy remains so we can see what it looked like before the explosion but look at those particles, same shape and size and velocities

Colors vary, but no biggie

That is badass

The original game uses a couple of different velocity patterns for the explosions, I plan to recreate them all but awesome that I got the test case working

[heady pine]

looks awesome! 👍

[heady pine]

Nice :)

[limber veldt]

And I worked it into a nice, clean bit of code for the particle generatorpy loc = [mutant.rect.x, mutant.rect.y] loc_y = loc[1] vel = [0, 0] rect_y_start = 0 vel_x = -8 vel_y = -8 for j in range(4): vel[0] = vel_x vel[1] = vel_y rect_x = 0 rect_y = rect_y_start loc_x = loc[0] for i in range(4): particle = Particle([vel[0], vel[1]], enemy_mutant, [loc_x, loc_y], [rect_x, rect_y, 5, 5]) vel[0] += 4 loc_x += 6 rect_x += 6 vel_y += 4 rect_y_start += 6

That makes all 16 particles

I always have to write all those particle assignments one by one before I can see the pattern and construct a couple of loops from it

Or anything like that

Next question...can I make them go in reverse to spawn an enemy

Yes, Just have to grab each of the particle positions after a certain amount of time then use those positions to recreate all of the particles with inverted velocities

So the particles have an age, when it reaches a certain value, the particle dies. When it dies, I print out the position and the velocity. Since there are 16 of them, I get a list of all of their positions and velocities

So now I just have to code a couple more loops with different values and determine how I'm going to kill them....I could just do the same and kill them after the same age

Since I'm using a constant FPS, that will work

[slate tendon]

Hello, is there any way to schedule aperiodic events in pygame? I want to have a sprite that essentially just has an onclick function that only runs when I click it

It seems like the current solution to this is to simply poll in the for event in pygame.event.get(), then if you get a MOUSEBUTTONUP event, check for collisions with the sprites of interest

But this seems really ugly to me

_
Is there no construct for asynchronous/aperiodic event handling such as click events? Something essentially like

btn1 = AClickableSprite()  # A user-defined class that implements necessary "clickable" traits
pygame.events.AddAperiodicEvent(
  condition=lambda: pygame.events.on_click() and btn1.wasClicked(), 
  response=btn1.clicked()
)

If this exists, that would be awesome. If it doesn't, maybe I'll write an issue

[compact portal]

"scheduling" can be a complex thing, because since timing is involved, which process is going to be around to care?

I dare you to whip up a solution or hack in an existing scheduling system 🙂

[limber veldt]

Well yes, yes I can

[narrow kestrel]

@next estuary I Want to get help and work with you in ursina engine I like your game's video

Please

[narrow kestrel]

This is

[wanton whale]

For any new game developers(or experienced), I stumbled upon this really well done video of a senior-dev refactoring a aspiring dev's console based Yahtzee game. It's worth a look. https://www.youtube.com/watch?v=l7E3y4te7sA

[dark lichen]

What do you guys prefer among visual studio and pycharm?

[mental jetty]

I prefer pycharm but I use sublime

[lunar creek]

make a multiplayer battle royale

[sand iris]

Can we use Pytmx with PIL?

[next estuary]

Nah I don't make shooters or anything where the goal is to kill someone

[barren shuttle]

hey i need a game dev to work with me on a game

[limber veldt]

import pygame as pg
from pygame.math import Vector2
import math

pg.init()
screen = pg.display.set_mode((640, 480))
my_rect = pg.Surface((20, 20))
my_rect.fill((255, 0, 0))
clock = pg.time.Clock()
BG_COLOR = pg.Color('gray12')

point = Vector2(320, 240)
mouse_pos = Vector2(0, 0)
radius, angle = (mouse_pos - point).as_polar()

i = 320
j = 200
speed = 3

done = False
while not done:
    for event in pg.event.get():
        if event.type == pg.QUIT:
            done = True
    mouse_pos = pg.mouse.get_pos()
    loc = Vector2(i, j)
    radius, angle = (mouse_pos - loc).as_polar()
    x = radius * math.cos(math.radians(angle)) + 320
    y = radius * math.sin(math.radians(angle)) + 240
    vec = Vector2(x, y) - point
    v = vec.normalize()
    i += v.x * speed
    j += v.y * speed
    
    screen.fill(BG_COLOR)
    screen.blit(my_rect, [i, j])
    pg.draw.line(screen, (0, 100, 255), point, mouse_pos)
    pg.display.set_caption(f'radius: {radius:.2f} angle: {angle:.2f}')
    pg.display.flip()
    clock.tick(60)```

That's a nice little piece of code

Enemy shooting at player in 2d? You'll need something like that

Gotta be a better way to do it though

[limber veldt]

And there is a better way

Much nicer, no need for angle```py
import pygame
from pygame.math import Vector2
import math

pygame.init()
screen = pygame.display.set_mode((640, 480))
my_rect = pygame.Surface((20, 20))
my_rect.fill((255, 0, 0))
clock = pygame.time.Clock()
BG_COLOR = pygame.Color('gray12')

point = Vector2(320, 240)
mouse_pos = Vector2(0, 0)

x = 320
y = 200
speed = 3

done = False
while not done:
for event in pygame.event.get():
if event.type == pygame.QUIT:
done = True
mouse_pos = pygame.mouse.get_pos()
loc = pygame.math.Vector2(x, y)
if mouse_pos != loc:
new_loc = (mouse_pos - loc).normalize() * speed
else:
new_loc = (mouse_pos - pygame.math.Vector2(x - 5, y - 5))

x += new_loc.x
y += new_loc.y

screen.fill(BG_COLOR)
screen.blit(my_rect, [x, y])
pygame.draw.line(screen, (0, 100, 255), point, mouse_pos)
pygame.display.flip()
clock.tick(60)```

I now have mutants who can chase the player along a wobbly path (making them harder to shoot)

[limber veldt]

Two enemy behaviors kind of done. The only thing they lack is shooting at the player and, given what I have now, that shouldn't be too hard to implement with a Bullet class

The lander behavior is gonna be the hardest. They have a few modes. First is like search mode, where they fly left or right toward the nearest human on the ground and once they get there, the descend to the human, pick it up then ascend toward the top of the screen. If they get there with the human, they turn into mutants

[grim abyss]

@sst can you help me with https://github.com/InZane84/WADdle-Plot-CLI/issues/1

[limber veldt]

And they're tough af

[grim abyss]

My math seriously sucks

[limber veldt]

Constraining to window is fairly straight forward

[grim abyss]

Can you explain concept?

[limber veldt]

Lemme look at your post a sec...

[grim abyss]

Ok

[limber veldt]

So I don't quite understand the question

How are you creating points?

Do the points move once they're created?

[grim abyss]

No, they are static.

So the raw points are in the range of -65k - 65k and I need to compute a translation offset for each vertex.

To plot them within a 640x480 window...

Then I need to scale the map so that it is within the window...

[limber veldt]

And the points each have an x and a y coordinate in that range?

[grim abyss]

Yes

[limber veldt]

Let's work that out...

The total range is 130_000

[grim abyss]

Ok

[limber veldt]

Right?

[grim abyss]

Basically, yes

[limber veldt]

65k - -65k = 130k

[grim abyss]

Yeah, I'm with you

[limber veldt]

So just divide 130k by 640 for each point

Let me work through that a sec...kinda buried in my own code at the moment

[grim abyss]

Hmmm

And for Y I would divide 130k by 480?

[limber veldt]

Nah

[grim abyss]

What about min and max? To get a rect of all the points?

I don't know how to proceed lol

[limber veldt]

So, (640/130000) * X, and (480/130000) * Y

[grim abyss]

And that translates the point to screen space?

[limber veldt]

Yes

[grim abyss]

Should I use float?

[limber veldt]

new_x = (640/130000) * point.x and new_y = (480/130000) * point.y

That depends, you might want to cast to floats, do the math then cast back to ints

[grim abyss]

I see.

[limber veldt]

The math will be floats

If they're not moving, I don't see any reason to really, but I don't know every usecase

[grim abyss]

Eventually I do want to add zooming and panning.

[limber veldt]

If you give a screen location as a float, it'll be turned into an int anyway

What are you using to draw your plot?

[grim abyss]

Then I want to move away from Turtle and over to arcade because of pyglet>opengl

I'm using the Tkinter Turtle module.

[limber veldt]

I've been working through a lot of that lately with pygame

Like transforming and translating surfaces

[grim abyss]

But I need Tkinter for widgets and a hardware accelerated surface so that's two event loops? How can that work? Threads?

Interesting...

[limber veldt]

I'm no pro with pygame, but I'm learning, no pro with anything really as a hobbyist : )

[grim abyss]

Same

We should team up

[limber veldt]

Maybe some day. My main coding focus now is this game

But first, fried chicken

[grim abyss]

Cool, but I was implying I would help you with the game first. Anyway, let me see if I can fix this since you have given me some insight..

[clear crane]

just wondering

[limber veldt]

Oh yeah, and since your range is starting in the negative, you'll have to offset that, just add 65000 to all of your point.x and point.y to bring it from a range of -65k through 65k to a range of 0 through 130k

Before doing your scaling math

Might just be able to abs() the result otherwise but I haven't worked that out

Nah

But that should be good

Just add the 65k to each one

That's a pretty massive scale, less than .005 per value in range

[grim abyss]

hmmm

I'm into now and I have fallen into "Indentation Hell" 😦

and infuriating situation that happens in VS Code

what is causing this? tabs? spaces? whiteline? i mean what

there is no syntax error, something has happened to indentation.

[limber veldt]

So plot() is a method, that entire block would be indented one more level

To be inside the class to which it belongs

And just break that if statement and conditions into the proper three lines it should be

That's the problem

Paste that line here for me, and the else: line too

I can't wait to do the enemy pods in this game. When they die, they spawn a few swarmers that come straight at the player hard and fast

That should be fairly easy to code the swarmer individual behavior but they kind of act as a group

[grim abyss]

I've figured it out. Code is in an inconsistent state and has mixed tabs and spaces for some odd reason

that sounds cool. you have art assets?

[clear crane]

might be stupid but can i thing coded in pygame be made into an app?
just wondering

[grim abyss]

@clear crane it's already an app. what do you mean

you mean mobile?

[clear crane]

yeh

[grim abyss]

An Applicatiion is compiled code that runs within a runtime environment

You should hit up Google for that. I haven't even tried to develop Python apps on mobile. I do know there is Kotlin + Android Studio

on iOS you would probably use Swift?

mobile is a different space?

[grim abyss]

@limber veldt thanks to you I'm on the right path. I just need to figure out now how to stay centered while scaling...but I have the points staying within the window!!!

[limber veldt]

Excellent

More maths

[grim abyss]

yup

[limber veldt]

In pygame, I would select a rect from the screen surface and scale it up to screen size then place it at 0,0 on the screen

[grim abyss]

so the screen surface has a different coordinate system from the screen size of say 640x480?

[limber veldt]

No, same thing

The surface is the size of the screen

But things can be outside of it, they just won't show on the screen

[grim abyss]

on this though 0,0 is top left so I need to Heighth / 2 and Width /2 to get center

I see how to do it now, I believe

[limber veldt]

So a rect of size 100 x 100 will be [width / 2 - 50, height / 2 - 50, 100, 100] to define the x and y of the upper left corner of the rect and the x size to be 100, y size to be 100

I'm not sure what kind of rectangle definition you need though

A rect centered in screen, I should say

[grim abyss]

width / 2 - 50 why -50?

[limber veldt]

I think that's generally how we define a rect though, that or just give the upper left point and the lower right point

T0 be centered in screen and 100 pixels wide, we have to take 50 from the left and 50 from the right of center

[grim abyss]

https://pythonhosted.org/planar/index.html this is the 2d geometry library I'm using

[limber veldt]

50 pixels left of center is center - 50

50 pixels right of center is center + 50

Right?

lol

[grim abyss]

https://pythonhosted.org/planar/bbox.html specifically this right now to try and get the rect of the world points

yup i got you

[limber veldt]

I have my enemy baiters flying to the player then doing a stretched diamond flight pattern around the player

Never really trying to hit the player, just fly around him

Eventually, they gonna fire bullets too

lol

This is great

[grim abyss]

🙂 sounds neat

[noble rapids]

i want to make a 3d game

but i dont know how to make

[cobalt lichen]

learn bro

[grim abyss]

@limber veldt are you here?

[grim abyss]

could someone help me with translating some points to screen space?

[dawn quiver]

does anybody know why when i am editing an animation sequence and save that and restarting the engine the animation stays as the last one?
(unreal engine 4)

ping at help please

[limber veldt]

So it looks like, at least from my watching of the videos, that some maybe even all Defender enemies have multiple behaviors like roam, search, attack, chase

And all of them well defined

Well, maybe not so well defined in a couple of them

Their transitions are so subtle sometimes, not so subtle other times

[limber veldt]

Sup man?

I wish I had the original game and could enable god mode just to watch the enemy flight patterns

I've done a lot of google digging, seems nobody has already analyzed these behaviors for me : P

Even found the source code but by the time I figure out exactly what that's doing...

The source is in 6809 assembly, not totally foreign to me, I use to know it but that's been decades

Color computer days, Coco3 was the shit

Part of the problem is with the term. Put the word "Defender" in a google search and you get a lot of tower defense hits

Anyone good enough please feel free to extract the enemy pod behaviors from this: https://github.com/AaronBottegal/Defender-Source-Code/blob/master/SourceCode.txt for me in either english or pyhon, thanks : )

Like I still remember the mnemonics

JSR = jump sub routine< --- meant to say jump there

LDB = load B register

STA = store A register

Some of them I have a hard time recalling but...meh, it's been 30 years

[nocturne nova]

is some one here familiar with pygame and can help me with a code for collision detection i have put my questions in a help channel atleast 5 times, i have tried to figure it ourt my self for weeks so if anyone can hekp i would really appreciate it

[limber veldt]

What kind of collision detection do you need? Simple rectangle/bounding box?

[nocturne nova]

sprites

[limber veldt]

Make your objects into pygame.sprite.Sprites and add them to a pygame.sprite.Group, done that already?

I'm just now learning some of this stuff for pygame, too

[nocturne nova]

i am pretty sure i have done that my error is that they are iterable

[grim abyss]

@limber veldt

i'm getting somewhere

need lines of course

[nocturne nova]

https://replit.com/@815398/dinoD#main.py well this is a link to my code if you would like to take a look

[limber veldt]

So in your draw_screen() function, you're doing something like: ```py
enemy_group.update()
enemy_group.draw(screen)

Sorry, lemme fix that...

[nocturne nova]

this is the first time i have made a game like this so

[limber veldt]

That indent, I dunno why...

[nocturne nova]

yeah i am pretty sure i do that

[limber veldt]

So then in my main loop I have just one line for collisions py hits = pygame.sprite.groupcollide(bullet_group, enemy_group, True, True)

[nocturne nova]

player.update_animation()
player.draw()

this is what i have

[limber veldt]

Your player class draw() method is probably not even necessary. You can draw the group as I did up there

None of my objects have a draw() method, group.draw(screen) just calls pygame to blit them to the destination

[nocturne nova]

i tried what you have and now it says that my object has no attribute to sprites

this is my player

[limber veldt]

Hard to read, but I try....

[grim abyss]

@nocturne nova that website is freaking cool! replit...

[limber veldt]

Ok, so your sprite needs a couple of things...

[nocturne nova]

yeah it is really easy to use and you have tons of languages

[limber veldt]

The formatting here is going to mess up the long-ish lines, but...```py
class EnemyMutant(pygame.sprite.Sprite):
def init(self, x, y):
super().init()
self.image = pygame.Surface((25, 24), pygame.SRCALPHA) # going to eventually be an enemy mutant, but a blank surface so far
self.rect = self.image.get_rect(center = (x, y)) # get the rect of that surface

But sprites need the image or surface or whatever is being drawn as self.image

And they need the rect of that image

[nocturne nova]

self.rect = self.image.get_rect()

i have that line in my sprites

[limber veldt]

And, most importantly, have to inherit from the parent class, hence the super().__init__()

Well, have to init the parent class, I should say

[limber veldt]

Excellent

Oh yeah, it is there, like I said though, that's hard to read for me here

As I look very closely, yeah..

[nocturne nova]

i am quite confused could i take a look at your code or like a github that you recomnend that could help

[limber veldt]

what was your error again?

[nocturne nova]

well with my former code

it was this

[limber veldt]

Ahh, so is asteroid not another pygame.sprite.Group()?

[nocturne nova]

that is correct

[nocturne nova]

sorry i dont know how to show it like this

[limber veldt]

So you have```py
asteroid = Asteroids()
asteroid_group.add(asteroid)

[nocturne nova]

asteroid = Asteroids() only this

[limber veldt]

You'd need to add that asteroid to a group of them for them to be iterable...I think

Iterate the group, of course, not the asteroid itself

[nocturne nova]

alright i am going to that right now

layer = DINO('player', 200, 325, 1.5, 5)

asteroid = Asteroids()

asteroid_group.add(asteroid)

player_group.add(player)

[limber veldt]

asteroid_group = pygame.sprite.Group()
asteroid = Asteroids()
asteroid_group.add(asteroid)

Then that hit detection line can iterate that group

[nocturne nova]

ohg thanks i was about to say that i get an error like that

[limber veldt]

And if there are problems along that route, fix the objects because that's how I'm using it and it's working

: )

Looks like a fun project you're working on

[nocturne nova]

what do you mean fic the objects?

thank you

asteroid = Asteroids()
asteroid_group = pygame.sprite.Group()
asteroid_group.add(asteroid)

player = DINO('player', 200, 325, 1.5, 5)
player_group = pygame.sprite.Group()
player_group.add(player)

[limber veldt]

What I mean is that I got them working the way I described but to fit into that kind of group, a sprite group, an object has to have certain things...it looks like all yours do from what I've seen so you should be good to go

[nocturne nova]

sorry to bother you again but hat is my code and it says that DINO (player) has no attribute to sprites

[limber veldt]

Let's see your DINO class

Or at least it's __init__() method

[frank field]

Hey @nocturne nova!

Uh-oh! It looks like your message got zapped by our spam filter. We currently don't allow .txt attachments, so here are some tips to help you travel safely:

• If you attempted to send a message longer than 2000 characters, try shortening your message to fit within the character limit or use a pasting service (see below)

• If you tried to show someone your code, you can use codeblocks
(run !code-blocks in #bot-commands for more information) or use a pasting service like:

https://paste.pythondiscord.com

[limber veldt]

Can you show the code around the line that's giving the error?

[nocturne nova]

this the error

[limber veldt]

Because it's true, there is no self.sprites = assignment in the __init__()

[nocturne nova]

ok so what does the self.sprites need to equal to

[limber veldt]

Change to player_group and asteroid_group, not player and asteroid

[nocturne nova]

like this

[limber veldt]

We add them to groups so we can use them in the hit detection, so we can't use the objects themselves, but the group containing them

No

Not like that

Delete that line

[nocturne nova]

ok

[limber veldt]

This line, make it this: py hits = pygame.sprite.groupcollide(player_group, asteroid_group, True, True)

[nocturne nova]

oh

[limber veldt]

We need the groups there

Not the objects

[nocturne nova]

ok so there is no error now how do i make the if....: line so i can tell it do something

[limber veldt]

Do the objects disappear from the screen when collided?
