[severe saffron]

that also don't let the client and server do RCE on each other

[manic moth]

tell me about it.

[severe saffron]

https://docs.python.org/3/library/pickle.html

[manic moth]

I'm still a noob, so I don't know what RCB is.

[manic moth]

oh, thanks. but pickle is safe to use between trusted clients right? a person from outside the network cannot inject malicious pickle data into my network, right?

[severe saffron]

They can if it's not over https

There isn't really a good reason to use pickle for this kind of thing over just sending the values you're interested in

[short wing]

hey mouse.get_pressed on laptop works or not?

[restive lantern]

On pygame?

[short wing]

yes

problem solved

[unborn bramble]

is py good to make games???

i never tried to make a game outside an engine

[olive parcel]

Yes

[unborn bramble]

i never was mutch into python i like going lower wen i program my dream is to be good at assembly

[formal cloud]

while you are there, you might as well build your own computer as well lmao @unborn bramble

c++ should be the lowest you wanna go

[normal silo]

There is good reason to be good at assembly. Compilers will often still generate crap (in this case you want to be able to read it so you can fiddle with the C++ code and compiler flags).

Plus in some cases you have to for things like SIMD.

Or controlling hardware.

[unborn bramble]

yes its kinda extreme but i love the idea of using almost hardware level comands to control pcs

[unborn bramble]

i think its useful to use low level hardware at the extreme like just a micro controller and make an entire game out of it

[formal cloud]

@unborn bramble there should be ways to make little assembly programs in your cpp i think if you really need an extra bit of juice in performance critical parts

i mean optimization only matters where your program bottlenecks the heaviest no?

[last moon]

actually I just looked into that yesterday, seems like it's pretty simple
to add to the points already made, imo learning how to do high level things in low levels helps gain an understanding of how to better benefit/use/understand those high level concepts

[unborn bramble]

the diference is simple wile programing imagine we are doing a factory assembly line

one is made to build any car in the world

the other is build to make one specific car only

[formal cloud]

the conversation seems to be getting at branching conditions:)

[unborn bramble]

year

kkkkkk sory i get exited easy with assembly

[last moon]

just a lil

[formal cloud]

you just gotta cut down on if statements, thats how you deal with it no?

what's more to it?

[last moon]

speaking of assembly/low level topics tho, do yall know of any resources on graphical drivers?

[normal silo]

Not exactly, there are situations in which not any one part of the code is really slow, but all the parts are just kinda slow, but not really. It adds up. In many situations people ignore this, but in the world of game engines, microseconds matter, the optimizations can be the difference between a jittery mess and a smooth experience.

[unborn bramble]

i am prety shure you can call shader scripts with assembly

but directely i am not shure its easy

[misty willow]

how do I Create clones(And control them) on demand

[last moon]

clones of what?

[misty willow]

a sprite

[unborn bramble]

class instantiation???

[misty willow]

oh sorry cocos2d w/ pyglet if I was supposed to say what I use

[unborn bramble]

i think the best on low level is the ability to shrink data and play with it beter

[normal silo]

(Also as computers stop getting exponentially faster, optimization will matter more and more as it will soon become the only difference between you and your competitors once most apps exist)

[unborn bramble]

there is a chanel where the guy always talks about "impossible" feats on games of older engines

[normal silo]

(Do same thing, but better)

[normal silo]

Even for fast machines it can matter a lot since they often provide custom instructions that the compiler will not make use of, because it can't.

[unborn bramble]

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

a nice example

[normal silo]

Yes I know of sonic 3d blast code.

The same still applies to modern hardware. Most of it is not used / wasted.

[unborn bramble]

unfortunatly

[normal silo]

https://en.wikipedia.org/wiki/Andy_and_Bill's_law

[unborn bramble]

is there a way to code in py on unity??

[unborn bramble]

nice trivia

what is the hardest thing you guys done in a game as a behaviour???

[formal cloud]

as a behaviour? @unborn bramble

[normal silo]

The hardest part is not any individual behavior in a game. It's how they all interact with each other. It's a combinatorics game that you can't win.

[formal cloud]

anything related to authorative and predictive multiplayer is hard D:

i keep creating mess over mess, i always find myself sitting on that pile of mess and thinking what i did wrong

[normal silo]

Multiplayer is making tons of compromises.

Can't have it all.

[formal cloud]

Kinda forces you to have cleaner logic in your game though

A state based game it forces you to make

[normal silo]

Yes, like multithreading your game logic, it adds burden to the rest of the team.

[formal cloud]

If you wanna go that route (if you mean data parallelism), you'd be better of with ecs

[unborn bramble]

in my case i am doing a project with a friend

to clear the mp problem i pretend to use a turn base

[normal silo]

ECS is not needed, you can often do something more simple, but yes it does help with that.

[unborn bramble]

and i pretend to make my game a site on the web

yes i have a server for that

i play games that are instaled on my server to save hd space

[formal cloud]

@normal silo simplest optimization could be stripping away parts of the game the seperate threads

[unborn bramble]

time flags???

if you timeflag some actions it might be solved not ?? to keep stuf syncronized

[formal cloud]

lets say you wanna do meshing
create the mesh in a thread and assign it in main thread when its done

@unborn bramble you'd have the main thread wait for worker threads somehow yes

[unborn bramble]

flags

[normal silo]

You can update all your game objects in parallel too if you want. You just double buffer your game state. Double buffering game state also let's you handle things that happen at the same time the way you want it to be handled rather than be random depending on the update order.

[unborn bramble]

no there is async

if the mesh is not ready skyp

i done that in my project

a screen analyzer

i made an "async"

[formal cloud]

id use a boolean to check if the thread is finished i guess

[unborn bramble]

i had no time for a real async so i done every loop the action will be done once

[formal cloud]

i made a mesher like that once and i wasnt waiting it to finish at all
id take it whenever its ready :)
it took its sweet time while main thread kept running

[unborn bramble]

and every loop the key number changes

before i had 2fps

now i have around 20

[unborn bramble]

memory is crying

we always have to hurt somewere

[formal cloud]

One should just use ecs if updating all entities in parallel is required

[normal silo]

It's worth it. @unborn bramble

You don't need an ECS to update all entities in parallel

[unborn bramble]

what is ECS

[formal cloud]

its just simpler

and cache friendly as well

[normal silo]

It's more simple without ECS. But yes ECS has better caching.

[formal cloud]

@unborn bramble entity component system

[normal silo]

Two different problems though.

[formal cloud]

@unborn bramble the data oriented way instead of object oriented

its pretty cool stuff but its more difficult to implement

[unborn bramble]

i see

[formal cloud]

@unborn bramble ecs main advantage is cache friendliness

and the way it updates entities, its easier to do data parallelization, task parallization too

[normal silo]

It's basically writing code in a way that the processor likes.

[formal cloud]

unity ecs does all that automatically in fact, checks what system depends on what and updates things in most efficient way

[unborn bramble]

t seems useful

[normal silo]

(realizing that modern hardware is limited by memory speed)

[unborn bramble]

i have an idea to make some mony in a weard way

and i imagine i will ned that way of coding

what you guys know about ai??

i mean like tensorflow not game basic ai

[formal cloud]

performance isnt always top priority though
you might find yourself deep in these stuff even if your project doesnt require any of that
better watch out when you are overengineering

[formal cloud]

i studied ml and deep learning one semester but it didnt do me much good tbh

though i believe i get the basics

[unborn bramble]

have you heard abut rl??

reinforcement learn

[normal silo]

It's what I do, head over to #data-science-and-ml if you want to discuss it with someone there.

[formal cloud]

yeah but not very strong on it, try me if you something

[unborn bramble]

i actualy need help

in the last step

but tis subject is here

i pretend on make tournaments

i will create enviroments

[normal silo]

Oh you were already in that channel.

[unborn bramble]

and have a twitch sowing and having ai's built by people figt one another

[normal silo]

People already have AI racing on twitch.

[unborn bramble]

yes but mine i will make a way so ex you can place yours

[formal cloud]

i doubt i will be able to help you but i'd still like to hear

[unborn bramble]

and see it against mine

in a mp game

i am actualy doing it now with help of retroarch

[normal silo]

Yes ML battle simulators exist as games.

IDR, there was a pretty popular MMO one.

[unborn bramble]

yes my ai is not frame atached

[formal cloud]

ai's are controlling the cars?

[normal silo]

On steam.

[unborn bramble]

yes

[formal cloud]

and you wanna compete with your own ai?

[unborn bramble]

i will as son as its able to race

the main reason is that crash racing is a game were you can see your car advance in the midel of the screen in the 4 player mode

i used that as points

[unborn bramble]

i mainly want ai x ai

specialy i had a problem with my script i cant do convolutional network

CuDNN problem with my agent

and i can also build some py games in cases were the game is imposible to generate points with screan read

or to have the points bin a cleaner way

[formal cloud]

you want to simply the footage you wanna feed to rl?

[unborn bramble]

no i will not allow memory read

yes my second step is try to recreate the newest thing

is an ai that creates "experience for the agent" trough youtube videos of speedruners

if it works i wil make a experience folder

so people will be able to train the ai mutch faster for the competition

[formal cloud]

you wanna crawl the youtube videos to make training footage for your ai?

but split screens are causing issues?

[unborn bramble]

it was already done

no because is an ai reading

and even buton pres ui may be readable with a good enough ai

is an ai to generate xp

not only

ass i said i have a server

[formal cloud]

wait wait

[unborn bramble]

my idea is to open a public folder where people can chekpoint their ai

[formal cloud]

you want to detect what keys are pressed by the player in the video
to come up with the loss you need in your algorithm

correct?

[unborn bramble]

an my script uses the checkpointed ai to compete

[unborn bramble]

in rl we dont talk loss

we talk scores

[normal silo]

Imitation learning is very easy, it's trivial to create a bot with better than human performance with it. I find it much more impressive if they did it with RL.

[formal cloud]

if ai is trying to press the button the player in the footage is pressing, then you wanna reward the agent
is that how its done in RLs?

[unborn bramble]

but it will be RL

just i wil give some shared experience for it

@normal silo can we talk at data chat??

[normal silo]

Maybe I don't get what you mean. If you think it's a good idea then just go for it.

[formal cloud]

oh wait, i mixed up imitation learning with RL i think

[unborn bramble]

i got one question

[unborn bramble]

more or less the important is that he advances in the scren not the imitation he ises the imputs image and all just to know how to train itself

[dawn quiver]

whats the problem??

[wet folio]

No indentation and you forgot the ":"

Also range(0) repeats the loop 0 times

[quasi valley]

yeah

[dawn quiver]

import kivy
from kivy.app import App
from kivy.uix.label import Label

class MyApp(App):
    def build(self):
        return Label(text="Lilkamfrmdaz")



if __name__== "__main___":
    MyApp().run()```
when i run this
my cmd doesnt come up

[unborn bramble]

wy you want cmd opening in a game??

is it a cmd game?

[crisp gust]

you put triple _ in the if statement

so its doing nothing

[dawn quiver]

how can i fix this

[quasi valley]

You need to provide the RGB values as a type for colors

Unless Grey is a variable

[crisp junco]

Screen.fill() takes a rgb color code (in tuple format) as an argument.
Probably seeing the error my guess is Grey isn't a variable.

just assign Grey to (128,128,128) which is the RGB color code for grey

that should be pygame.Color('grey')

[dawn quiver]

Google it

[slender olive]

Hi I have heard that if my pygame event is pygame.MOUSEBUTTONDOWN, I can check which button it is by doing event.button, which is an int.
Are there any constant variables in pygame that represent which button was pressed (like pygame.MOUSEBUTTONDOWN just for this specific event)?

[scarlet walrus]

anyone know about ursina engine?

[scarlet walrus]

pygame.mouse.get_pressed()

im pretty sure

the value is
(False, False, False)

which stands for
LMB, MMB, RMB

[quasi valley]

i thought get pressed was only for the keyboard lmao

must be going crazy

[scarlet walrus]

hey

do u know about ursina engine?

[quasi valley]

no havent used it

[scarlet walrus]

oh k

i need help on ursina

[quasi valley]

looks interesting though

might check it out

[olive parcel]

@scarlet walrus if you described your problem, perhaps someone could help. If you don´t describe your problem, then it´s not likely that people will respond.

For what it´s worth, @tranquil girder is the most knowledged about Ursina around here.

[iron trail]

why am i being told that board has no attribute black?

class Board:
    def __int__(self):
        self.x = 0
        self.y = 0
        self.black = pygame.image.load("resources/square gray dark _1x_ns.png")
        self.white = pygame.image.load("resources/square gray light _1x_ns.png")

    def draw(self, win):
        sizes: int = int(WIDTH / 10)
        bl = pygame.transform.scale(self.black, (sizes, sizes))
        wh = pygame.transform.scale(self.white, (sizes, sizes))
        iswhite = False
        for y in range(WIDTH):
            if iswhite:
                iswhite = False
            else:
                iswhite = True
            if y % sizes == 0:

                        if iswhite:
                            win.blit(wh, (x, y))
                            iswhite = False
                        else:
                            win.blit(bl, (x, y))
                            iswhite = True

[olive parcel]

@iron trail because you called your constructor __int__ instead of __init__

So it doesn´t get called.

[hybrid briar]

Hello

anybody here??

[olive parcel]

@hybrid briar what makes you think otherwise?

[green relic]

Hello?

Can someone help me, I am tying to make a jump function in pygame but when I call it by pressing "w" it just teleports me up instead of raising me and me being able to see how the sprite lifts up.

        if keys[K_w] and falling == False:
            falling = False
            for i in range(150):
                self.rect.y -= 1
                time.delay(1)
            falling = True

[dawn quiver]

help. how can i make a screen that displays a typewriting text?

with pygame

@solar ferry can you help?

[iron trail]

finally got the base of the game working

literally took all day

[green relic]

?

[iron trail]

sry

nvm

[green relic]

ok

[iron trail]

u using sprite?

[green relic]

wdym

Yes...

[iron trail]

is there an image or is it just a box

[green relic]

Image

[iron trail]

okay

you are moving the hitbox slowly

you gotta change the image too

[green relic]

Do you know how?

[iron trail]

do you have the image being redrawn with variable x and y values?

[green relic]

Pretty sure yes

[iron trail]

increment the x and y values of the image aswell as the rect

[green relic]

This is all I have

[iron trail]

i am confusion

i have never used the sprite parent before

what does it do?

btw movement should be in the game loop, its good practice

where do you call the reset() function?

[green relic]

Already have all that.

[dawn quiver]

why doesnt i let open up a window???

I'm working on a platformer with pygame, I'm trying to add rope swinging, I got it mostly working but it's not very fluid, I was wondering if there was a good engine for rope mechanics for pygame.

[restive lantern]

that for loop is the problem

[restive lantern]

you are executing the entire for loop in a single frame or cycle. when in reality you have to move the character y through various frames

so what is happening is that the character jumps in a single frame and that is too fast

[restive lantern]

did you already figure this out?

[dawn quiver]

nope

[restive lantern]

what exactly do you need?

do you just need to display the font?

[dawn quiver]

yes

[restive lantern]

do you have a typewriter font on your computer?

[dawn quiver]

i am on mac

idk

i just want like when i run it i typewrites the text

"typewrite" not just display

idk how to do this

[restive lantern]

that is quite a challenge i gotta say

[dawn quiver]

i know but it would be so cool

i wanna pranks someone

@restive lantern or lets just do the display font

its ok

how do i do it?

[restive lantern]

have this function to display text

pygame.font.init()
font_type = pygame.font.Font('Retro Gaming.ttf',20)

# where it says 'Retro Gaming.ttf' you have to put the name of the font with .ttf extension at the end
# I used the font called 'Retro Gaming.ttf' for my game but you can use any font

def show_text(words, color, position):
    text = font_type.render(words,False,color)
    surface.blit(text, position)
    # surface is a variable that contains a surface object where you want to show the text
    # it can aslo be tha main window

[dawn quiver]

am i supposed to copy the py?

oh now thanks

wait

[restive lantern]

yea you can

[dawn quiver]

thanks

thanks so much

tf @restive lantern

[restive lantern]

did you read the comments?

[dawn quiver]

oh

[restive lantern]

the green lines?

[dawn quiver]

now?

[restive lantern]

did you import pygame?

[dawn quiver]

i am not the best in english so sorry

wdym

yes i have pygame installed

[restive lantern]

just type:

import pygame

in the first line

[dawn quiver]

oh

lol?

[restive lantern]

the is the thing you have to make sure such a font is installed in your computer

i dont know how to do it in mac i use windows

[dawn quiver]

oh so its not installed?

wait ill be using arial

[restive lantern]

probably there is a font but you have to find the specific name

[dawn quiver]

yeah where do i find my. fonts?

[restive lantern]

i dont know i dont use mac

you will have to search in the internet

[dawn quiver]

oh let me see on safari

[restive lantern]

you can also change this line

font_type = pygame.font.Font('Retro Gaming.ttf',20)

to

font_type = pygame.font.SysFont('Arial.ttf',20)

if the font you want to use is not a custom font
the 20 signifies the size of the letters

[dawn quiver]

what am i supposed to search up?

[restive lantern]

how to see the fonts installed in mac

[dawn quiver]

oh now i can see

[restive lantern]

and how to install a font in mac if you need to install it

[restive lantern]

you will have to search a font that looks like a typewriter

if there is such

[dawn quiver]

what now?

[restive lantern]

yea you can us that

[dawn quiver]

waot

wait

[restive lantern]

yea?

[dawn quiver]

am i supposed to be a bot at coding or why is it like that?

i am stupif

stupid

[restive lantern]

you can also change this line

font_type = pygame.font.Font('Retro Gaming.ttf',20)

to

font_type = pygame.font.SysFont('Arial.ttf',20)

if the font you want to use is not a custom font
the 20 signifies the size of the letters

[dawn quiver]

example?

[restive lantern]

since the font is already installed in the computer it is not a custom font

pygame.font.init()
font_type = pygame.font.SysFont('American typewriter.ttf',20)

def show_text(words, color, position):
    text = font_type.render(words,False,color)
    surface.blit(text, position)

[dawn quiver]

ok it works but it doesnt open up the window

[restive lantern]

you still need to do a lot of stuff though

[dawn quiver]

why?

[restive lantern]

you need a sruface and the main loop and the event handler for closing the window

lot of stuff

[dawn quiver]

what you mean

installing ?

[restive lantern]

no no

like in the code

[dawn quiver]

oh and how ?

[frank field]

Hey @restive lantern!

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

[dawn quiver]

like what am i supposed to tipe

send me private\

they dont let you send files

[pine marlin]

You need a main loop that displays the surface

[dawn quiver]

somone is helping me already but thanks for the help offer

[dawn quiver]

maybe can you help pls ?

when i run this it doesnt display any text

[dusky sequoia]

I think you are missing alpha chanel

you have the r,g,b. I believe you are missing a.

so try in your color (0,0,255,255)

[crisp arrow]

I need help on how to freeze everything on my screen but the player(i used pygame to make the game)

if i use time.sleep it freezes the whole screen

if someone has the solution to this please DM me or ping when respond(i would prefer DM)

[restive lantern]

maybe you could make a loop inside the main loop where you only move the character

[crisp arrow]

but how would that freeze every other object?

[tranquil girder]

things don't move unless you tell them to
so just don't tell them to move
just the player

i wanted tryid to do a matrix screen saver but when i run it it appears only for 1 seconds what should i do????/

why is it like that

[olive parcel]

@worldly flare is move even being called every frame? Looks like it'll only be called when the event loop quits.

[worldly flare]

it works

U should check again

[quasi valley]

you're using == which checks if player.r is false, instead of = which assigns it to false

so you can change player.whatever_key_pressed == True to player.whatever_key_pressed = True

then it should work

hey guys i have a question,
if i and a friend were to start learning to make games with python, is there a chance we can make money from it? if yes, how?

i'm a beginner and i havent started yet, yeah

Im just gonna say one thing. Steam has 30 000 games in its store

Just think about it

What makes you think that your game will be more relevant than any other of those 30 000 games?

Game dev does not pay well if youre a standalone dev making indie games. The chance you even get a player that isnt someone you personally know is very low

[signal plank]

There is also a survivor bias. You hear about the 10 indie games each year that make it to the top. But what about the 100000 project that didn't make it?

[signal plank]

I think a lot of developers (especially those who use discord) got to programming because of games. Thinking "hey, I can do that as well" or tweaking around with mods etc.
I also think that a lot of those developers realized that there is much more to web development that you dont see as an end user. And a part of them sticked to other programming "genres"

[tranquil girder]

camera.clip_plane_far = some_value
but that won't fix your problem
you should make chunks instead of individual blocks:

Hi Guys I want make Fake (Bot) Players For Servers

Does anyone have any information about this topic?

For what game?

Most games have strict rules against bots. If you are making test bots for your own game.. that is a different thing.

Be sure you read the rule before you dig into this

uhh so
i don't know how to say this but

repo one
https://github.com/Craig-Macomber/Panda3D-Terrain-System

repo two
https://github.com/Craig-Macomber/infiniteRalph

uhh so the first repo says to add it as a submodule so i have
and when i try to run the second one
instead of the error ModuleNotFoundError: No module named 'terrain'
i get
ModuleNotFoundError: No module named 'terrain.bakery'
now the thing is
the first one aka submdule
has a bakery folder
so the question being how do i add something.something as a submodules

[cloud mica]

A text game engine, you play through text. Like a MUD or something. It describes your surroundings via text, and you type commands to move around, and attack and stuff.

[thick sequoia]

can anyone here help with Panda3d :>

[olive parcel]

@thick sequoia depends, what is your question?

[thick sequoia]

whats the correct format for specifying a path to a 3d object

cuz im just playing around with Panda and want to render a cube i made in blender

[olive parcel]

Panda always uses UNIX style paths even on Windows, full paths would go like /c/Users/yourname/blah/blah

[thick sequoia]

k thanks

[olive parcel]

Though you usually want to work with relative paths

If you specify the path relative to the directory where your main .py is (using forward slashes) everything should work.

[thick sequoia]

im using this path "/myusername/Desktop/Python3dGame/Scripts/cube" but its not working

[olive parcel]

@thick sequoia missing /c at the beginning

But I recommend a relative path.

I was thinking about high speed collisions in games, where the time that the two objects are colliding is shorter than an update frame, so you can do funky things like phase through walls just by going stupid fast. Would a physics engine that ray-steps the collisions be able to circumvent this by calculating a ray on which the object would move between updates and then collision checking that ray instead of the object? naturally you would have to collision check the ray for each vertex, so it would be expensive, but in theory it would eliminate high-speed phasing...

[dawn quiver]

Any high speed calculations are not possible, not in python atleast. Plus, you wish to do things, faster than an update frame, which is definitely not possible. What you could do is, bug out the game! the collisions will fail, if you go faster than what the compiler can process.

@misty shell

[last moon]

I think it’d depend pretty heavily on how complex the collision is (squares hitting vs a skeleton hitting something) but you’d want to do some sort of bounds checking when updating the position (if pos1 > wall, pos1 = wall), I’d personally approach it with some sort of filtered ray tracing - pick a couple points on the model when objects are close to each other and see if they’ll intersect - but I’m assuming you wouldn’t need to do it for each vertex unless you’re doing simulations (don’t quote me on any of this I haven’t dug into it). Either way I think you’d only be ray-stepping in the sense that you’re drawing rays the length of dpos (but again if you wanted more realistic physics you might step to calculate momentum (?))

[proper peak]

Would a physics engine that ray-steps the collisions be able to circumvent this by calculating a ray on which the object would move between updates and then collision checking that ray instead of the object? naturally you would have to collision check the ray for each vertex, so it would be expensive, but in theory it would eliminate high-speed phasing...
What you're describing is called Continuous Collision Detection and many physics engines can do that.

they have to do multiple CCD sub-steps per normal step for that, though

@misty shell https://nphysics.org/all_examples3/ Here's one physics engine that has a configurable web demo, including CCD stuff

[sacred lake]

What is the best module for creating games?

[crisp junco]

really depends

you can check out pygame,arcade,ursina all of them are good

[grand imp]

What kinds of games do you want to make?

[sacred lake]

2D games

[grand imp]

How much experience with python and games development do you have?

[grand imp]

The amount of experience you have with both will be helpful in determining what framework would be the best fit

[sacred lake]

I want the best only -_-

[grand imp]

"Best" depends on all the stuff I mentioned above.
If you want to be able to make a game fast and don't care about the amount of freedom you have to customize, then you won't want the same frameworks as you would if you want extreme control and can take time to implement.

Pygame is good for when you want maximum control, but it can be very clunky and doesn't support all the features you'd want out of the box. For example, it doesn't really support drawing shapes on its own.

Pygame Zero is a wrapper around pygame that simplifies some things. It's beginner friendly.
Wasabi2d shares a lot in common with pygame zero and was created by the same author, and supports more advanced features out of the box than either of the above.

Pyglet is very good at giving you fast low-level access to OpenGL, and seems to be nicer than pygame imo, but it will have a lot of the same issues as pygame in terms of requiring you to do a lot of work to get something flexible together.

Arcade is nice, and it's a library I'm trying to contribute to. It tries to provide some higher-level abstractions for things like the UI and collisions, and has built-in support for Pymunk, a physics engine binding in python. However, some of the UI features are in active development to fix some annoying issues. If you just want to show sprites and unchanging text, this one can be a pretty good choice. It also supports shaders out of the box.

@sacred lake does this help at all?

[sacred lake]

Yes

[grand imp]

If you're a beginner, you'll want something like Pygame Zero or Arcade

Especially if you don't have much experience in programming.

I don't know how beginner friendly wasabi2d is, but it re-implements some APIs from Pygame Zero, so you might be able to move to more easily it if you need more features after starting on Pygame Zero.

Out of the frameworks I've listed, I've only used directly used Pygame and Arcade.

Oh

there's one more framework that you might be interested in eventually, but I don't recommend it for beginners. Kivy can build apps that run on phones.

The big downsides are that it's very complicated in comparison to some of the frameworks above, and it's not really a games framework at all.

[sacred lake]

I have a lot of experience with Python, but I don't have much experience with games 😦

[grand imp]

Well, take a look at the frameworks I've mentioned and see if any seem like a good fit for you

[manic moth]

Hello, I'm trying to make an online multiplayer Pong game, this is my first proper game, and in one part of the server.py, I'm running a while loop under which all the data transmission between client & server happens. But I'm not sure how do I disconnect a client properly. I'm using sockets, pygame and threading. This is the while loop snippet in server.py :

while True:
        try:
            data = pickle.loads(conn.recv(2048))
            
            if not data:
                print('\nyes data was "".')
                break
            
            else:
                players[player] = data
                conn.send(pickle.dumps(players[opponent]))

        except Exception as e:
            print(e)
            break

I was under the impression that whenever a client socket disconnects, it sends a "" to the server upon disconnecting. Hence my 5th line is if not data because data would be equal to "" when the client disconnects. But my script never executes that if condition & the yes data was '' never gets printed , instead it goes to the except block and prints e which is the error Ran out of input. Can someone please help me how to cleanly disconnect a client socket from server. Thanks

[crisp junco]

conn.close()?

[manic moth]

yeah, I'm already using that, actually I'm spinning a new thread for every client that connects to the server, and here is the whole thread :

def threaded_client(conn,player):
    global client_count

    if player==0:
        opponent = 1
    else:
        opponent = 0
    
    send_player = conn.send(pickle.dumps(players[player]))   #send player initially to 1st client
    send_opponent = conn.send(pickle.dumps(players[opponent])) #send opponent to 1st client
    #the while loop
    while True:
        try:
            data = pickle.loads(conn.recv(2048))
            
            if not data:
                print('\nyes data was "".')
                break
            
            else:
                players[player] = data   #players is a database for clients, therefore this line updates the database with the current client
                conn.send(pickle.dumps(players[opponent])) #send the opponent to the connected client

        except Exception as e:
            print(e)
            break

    print(f"Client {conn.getpeername()} disconnected!\n\n")     
    client_count -= 1
    conn.close()

hello

does anyone know if these two lines still work?

        new_rect = rotated_image.get_rect(center=self.img.get_rect(topleft= (self.x, self.y)).center)

my bird is not tilting when falling

https://paste.pythondiscord.com/oqeyacovik.py this is the code so far

[dawn quiver]

how can I shorten this line that I'm drawing between the player and the cursor ?

I want it to be a fixed size but always go in the direction of the cursor

[lunar venture]

clamp the x and y

[dawn quiver]

maybe simply getting the angle between the character and the cursor should be the way to go but I suck at maths

what do you mean by clamping them ?

[lunar venture]

actually, when the mouse is close to the player, should it stay long or be short enough to fill just the distance between the cursor and the player

[dawn quiver]

always the same size. In fact I'd like to use maths to retrieve the angle so that I can rotate my sprite towards the cursor

I'm testing by rotating this line for now

[lunar venture]

wait is it a sprite or is it like a line

[dawn quiver]

it's a line, but I just want an angle value

from that I can use sin and cosin to draw a line

[lunar venture]

you can just calculate like (y1-y2)/(x1-x2)

that can be your angle kinda

actually it will not work for same x's so never mind

[dawn quiver]

I can have an exception if x1-x2 is equal to zero

[lunar venture]

well then there you have it

[dawn quiver]

the formula you gave is giving me the lenght of the line

not the angle

[lunar venture]

it's the slope of the line

not length

[dawn quiver]

the slope ? I'm not a native speaker

what does that mean ?

(And I also suck at maths)

[lunar venture]

https://en.wikipedia.org/wiki/Slope

[dawn quiver]

oh nice

[dawn quiver]

and I can get the angle from the slope I guess

[lunar venture]

those are your edge cases for the forumla

[dawn quiver]

by doing arctan(m) with m being the slope ?

I'm going to try that out, thanks !

[tranquil robin]

@abstract light How can I make the main code that looks like this def main_Loop(): global location #print(room.get('Main Hall', 'item')) while adventure == True: for x in npc: print(x) npc_Action(x[0]) desc = room.get(location, 'desc') exits = room.get(location, 'exits') if room.get(location, 'visit') == "False": globals()[room.get(location, 'event')]() print(desc) print(exits) global advaction advaction = input('>') if advaction == "quit": sys.exit(0) print(advaction) explore_Dungeon()
run simultanously with a pygame screen that displays a fixed image that only refreshes/changes when the main code tells it to. For example, a refresh from the main code would tell pygame to erase everything on screen and blit the appropiate sprites to the screen

[dawn quiver]

I managed to do it !

yellow line is generated using trigonometry

here's how I did it :

mouseX, mouseY = pygame.mouse.get_pos()
relativeCoordsX, relativeCoordsY = mouseX - player.x, mouseY - player.y
angle = math.atan2(relativeCoordsY, relativeCoordsX)

linex, liney = (player.x + 50 * math.cos(angle), player.y + 50 * math.sin(angle))

pygame.draw.line(screen, (255, 255, 0), (self.x, self.y), (linex, liney), 3)

sorry for bad formatting wait a second

50 being the lenght of the line

[dawn quiver]

And I now have this cool tank player controller

[lunar venture]

Awesome.

[dawn quiver]

pygame is actually fun, it's the first time I try to code a "game" in pure code without using any external engine

(the gif has been sped up, the game is not that fast)

now the question is, without the concept of camera, how can I create a world bigger than the size of my screen ?

Maybe different screens would be easier (going trough a way of the screen is moving the player into a different scene) but I wonder if it's technically easy to create a scrolling background

[normal silo]

Always draw the tank in the middle of the screen. When you move, move everything else in the opposite direction of intended motion.

(In video games, the camera does not move, everything else moves around it, giving the illusion of a moving camera (though the camera does have changing coordinates, it's just a way to think about it))

(camera x = 10 -> everything else's x -= 10)

[dawn quiver]

that's very clever

but it does not allow for dynamic camera movement

like moving when the player approaches the border of the screen for example

[normal silo]

Yes, so you have a camera position, and the tank also moves with everything else relative to the camera.

(otherwise, you can just have the tank's position be the camera position)

Preventing the camera from going out of bounds (for rectangular bounds) is as simple as clamping the camera's position (after it was set to the tank's position).

[dawn quiver]

I see

thanks for the feedback !

[analog barn]

[last moon]

id suggest using some sort of error handling to make sure the args you need are actually gotten

for readability's sake i'd recommend using optional args instead def __init__(self, app, size, bottom=None, topright=None, ...)

or use default args depending on the use case

@mellow citrus see this

how that thing create a line break after is

[mellow citrus]

u need to calculate the image size

and then decide the font suze based on it

@maiden seal ig

[maiden seal]

no

font size is fixed for me

in my use if want fix it

@mellow citrus

[mellow citrus]

its # find biggest font size that works
fontSize = int(imageSize[1]/5)
font = ImageFont.truetype("/Library/Fonts/Impact.ttf", fontSize)
topTextSize = font.getsize(topString)
bottomTextSize = font.getsize(bottomString)
while topTextSize[0] > imageSize[0]-20 or bottomTextSize[0] > imageSize[0]-20:
fontSize = fontSize - 1
font = ImageFont.truetype("/Library/Fonts/Impact.ttf", fontSize)
topTextSize = font.getsize(topString)
bottomTextSize = font.getsize(bottomString)

idk

as i told u

u have to check image size

and then decide the best font sizee for it

i don't think there is a better solution

@maiden seal idk

this is everything i can help with srry im not that gud at Python

[versed turret]

i used time, requests

[finite briar]

Right, I know assorted stuff

oh and datetime maybe?

[olive parcel]

Use what you need for your game 🙂 I´m not sure how webbrowser would even come in in a game

[finite briar]

Probably for the help links

that's my guess anyways

I figured that but like i didnt know if there were any specific modules that would be super helpful if i knew before i got started with anything lol

[mint zenith]

My approach is to look stuff up as I encounter it. I don't think you should worry about learning those modules ahead of time. Just figure it all out as you go along. It's more important to focus on concepts rather than on library specific implementation details

Maybe numpy is an exception since it is a relatively complicated library

But you're assuming you'll need it without knowing for sure that you will, so keep that in mind

Hey, I dont know if this is the exact channel to be asking, but i'm working on a rouge-inspired game that has map generation. Are there anyway good ways of generating rectangles in a 2D array? The format of which is: map=[[1,2,3],[4,5,6],[7,8,9]]

I've tried manually changing each of the items in each list to make vertical and horizontal lines. I prefer if you ping me to help me

[normal silo]

pygame's Surface's blit function can blit only part of the source onto the destination. If you have a sprite sheet, just blit the current frame (part of the whole sheet).

[stray obsidian]

yoo

can someone help me with pygame here?

.

player = pygame.Rect(screen_width - 20, screen_height / 2 - 70 , 10 , 140)

player_speed = 0

player.y += player_speed

every thing works but i don't understand few things

[cold storm]

@stray obsidian

when you press the key it emits a down event

when you release it, it emits a up event

so basically

us there a event for that key
if it's a down event -> do this

if it's a up even -> do that

you could also likely have a 'held' event (I don't use pygame) but bge input is very similar

[stray obsidian]

i got that part what i did not get is that if i press the upp key it goes 7 +7 +7 and when i release it subtracts 7 ........so this means the player should go back a little but it stops why is that?

[cold storm]

add seven wait

on release remove 7

so it goes
0->7 when you start pressing the key

and from 7->0 when you release it

            self.PRODUCTS = {}
            self.products_list = []
            messagebox.showinfo("Done!", "All products cleared successfully")
            self.clear_all_products_win.destroy()
        elif self.clear_all_products_entry_var in no:
            self.clear_all_products_win.destroy()
        else:
            messagebox.showerror("Please enter Yes/No!")
            self.clear_all_products_win.destroy()

basically upon pressing a button on the menu, a popup appears asking for an input in this case is self.clear_all_products_entry_var

i want the user to enter yes/no and execute different functions(popup feedback message etc)

but in this case no matter what i enter in, i get the error message "Please enter Yes/No!"

why is that so?

[olive parcel]

I suggest adding a print statement of self.clear_all_products_entry_var to see what it does contain

Also, you can simplify that code by doing:
if self.clear_all_products_entry_var.lower() == 'yes':

[marble pewter]

ooo very smart

it came out as PY_VAR4

and 5 subsequently

[olive parcel]

Can't possibly comment on that since we don't see the code where it is assigned

@marble pewter it's called shotgun debugging, and is the method that always works if all other tools fail 🙂

Wait, shotgun debugging refers to something else

Hello everybody

I want to make this game: https://armorgames.com/unpuzzle-game/18230

and I need some help or source code please

[surreal talon]

Hi, Im really struggling with this concept and I cant find anything on the web. Essentially I have a player that rotates towards the users cursor. And I want to add in a shooting system that shoots out projectiles from the player. But Im not sure how to shoot it out of the player in the direction the player is facing?

[simple belfry]

What is the best 2d game dev framework for python?

[quasi valley]

Probably pygame tbh

[indigo pulsar]

This's normal that my parallax can be jerky ?

Maybe for a game it's better to use compiled language to stop read and execute line by line

And win time

[simple belfry]

It's quite old, is it still useable?

[quasi valley]

Yes, very, I think a lot of the stuff in this channel is about pygame

I in fact use it a lot, although I’ve never actually finished a game lmao

[simple belfry]

Ok thanks

[quasi valley]

Yep

[indigo pulsar]

anyone has an answer ?

[cold storm]

Hey all

Just wanted to remind you to test UPBGE fork of blender for making python projects for fun or otherwise

you can call BPY in game and manipulate meshes / blender data

as well as all the old features BGE offered in blender before 2.8 with some slight differences

https://www.youtube.com/watch?v=MaYVCYXIU9o

I am using the game engine to move around in this video

[bold quartz]

You did put a fps limit right. Jerky motion is common when you are rendering multiple things on screen but are not cleaning your screen

[indigo pulsar]

I don't put anything about fps.
To show on the screen I call my fonction that can put surface onscreen then I update screen and a fill my screen in black

[finite briar]

import pygame
pygame.init()

width, height = 500, 500
white = 255, 255, 255
center = 250, 250
base = 50
blue = 0, 0, 255
fps = 60
clock = pygame.time.Clock()
screen = pygame.display.set_mode((width, height))
pygame.display.set_caption("Game 1")
def game():
    running = True
    while running:
        clock.tick(fps)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                running = False
        screen.fill(white)
        pygame.display.update()
        Nuke = pygame.image.load("C:\\Users\Felix Laptop\Downloads\Spaceship1.png")
        pygame.blit(Nuke, (250, 250))

    pygame.quit()```
Erm... The window opens and closes but i cant figure out why ;-;

[tranquil girder]

Do you call game()?

Interesting

Ya see i was just uh testing you, right, right

Hi I am noob but I want create a game,, how can I begin?

[grim wraith]

ok

in python

@woven compass

[woven compass]

yes

@grim wraith yes, on python

[grim wraith]

what game wanna develop

[lone wyvern]

before u make a game u should learn the basics

like loops, if statements, scoping

variables

etc

[grim wraith]

@lone wyvern he has a game in mind i wanna make him learn the code according to his game'

[lone wyvern]

great discord crasher

[lone wyvern]

sure but it'd be way more useful to learn the basics so he's more flexible making different games

[grim wraith]

yea i will make him learn before he makes a gme

[proper peak]

@simple belfry note that pygame has a significant limitation of only rendering on the CPU (it can't use the GPU at all), making it unsuitable for games with a lot of stuff happening

decent for learning gamedev, though

[tranquil girder]

I thought that's no longer true with pygame 2

[proper peak]

Huh, is that the case?

Hmm, I see some mentions that pygame2 is supposed to use sdl2, but I can't find how to actually use that functionality, unless it's just on by default

[simple belfry]

I thought to use it for platformer or top down games

[proper peak]

Most stuff like that would be fine in pygame too, it's only when drawing tons of objects that you might have problems

[simple belfry]

I don't think making FPS in python is a right way XD

[finite briar]

import pygame
pygame.init()
fps = 60
screen_size = (500,500)
white = 255, 255, 255
center = 250, 250
blue = 0, 0, 255
base_rad = 50
clock = pygame.time.Clock()
screen = pygame.display.set_mode(screen_size)
running = True
while running:
    clock.tick(fps)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
    screen.fill(white)
    pygame.draw.circle(screen, blue, center, base_rad)
    Nuke = pygame.image.load("C:\\Users\Felix Laptop\Downloads\Spaceship1.png")
    screen.blit(Nuke, center)
    pygame.display.update()
pygame.quit()
``` I'm not crazy... right? The blue circle and the Spaceship should be the same location..?

Cause they arent ;-;

[leaden turtle]

maybe its the PNG, try manually place the nuke in the centre instead of using centre variable

[torpid pewter]

i'm using pygame, and when i move the window around my game stops and won't update until i stop moving the window. is this a problem with my game, or is it an issue with pygame in general?

[next sun]

how do i load a image according to the screen resolution

[hollow egret]

hello, I made a game dedicated to retro minigames all in one. I need some testers though, im willing to pay 5 usd for 20 mins of testing

even a ps7 if you must

[valid crater]

cough

i need that voice verification

you knpw

[coarse gazelle]

Okay, so this isn't really about game making, but it's something similar. I'm planning to work on something that'll require me to load an image into memory, split it into an RGB array of bytes, then work on individual bytes (R, G and B values of each separate pixel), and then save the new, modified image. It'd be cool to be able to display it in real time, as I'm modifying each pixel too, which is why I thought Pyglet may be the way to go here.

But I figured I'd ask here first, if this would be doable with something like PIL + Numpy arrays

not sure how I'd handle real-time displaying in this case

Thoughts?

[proper peak]

I've done something like that with pyplot.imshow before - showing each frame

not very nice, and pretty slow

[coarse gazelle]

pyplot, huh?

[proper peak]

a game library is indeed probably a good choice

[coarse gazelle]

Yeah, figured as much

I've done a simple snake game in Pyglet before

so I'm kinda familiar with the lib

Should I go with that in this case too, or do you have something that'd fit better?

I need this to be pretty fast, I can imagine that serializing an array of bytes into a sprite, and then displaying it, is gonna be quite slow

Hmm

Well, okay, I'll try it with Pyglet, and see how it goes

[pine marlin]

pygame.draw.circle takes coords for the circle centre as a parameter, but when you blit an image the coords are for the top left corner of the image.

Hence why the nuke is to the southeast of the centre of the circle.

[finite briar]

Helloooo, i am very new to programming and I was watching a tutorial on how to create a bot that plays Flappy Bird, and am getting this error on the "import pygame" line, and i already type "pip install pygame", and "pip install neat-python". And i don't know what to do. As i said, i am very new so please forgive me if this a stupid thing to ask.(And also forgive me for my english)

[hard horizon]

try this py -m pip install -U pygame neat

[atomic sapphire]

It download something but the same error

[hard horizon]

how are you running your module?

run it from terminal py module.py

Sorry for the question but what is that

I just press this button

yeh don’t press that just run your module from the shell itself

[atomic sapphire]

I felt stupid for this but what is the shell

[hard horizon]

where you just typed pip install

command line

[atomic sapphire]

Oh

I see

[hard horizon]

yeh just type py FlappyBirdAI.py

[indigo pulsar]

Hi

question about jumping on my code

When I use rectangle to show how it works, everything was good

but when I put surface the code doesn't show the same result

here the function of my class to jump

[frank field]

Hey @indigo pulsar!

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

[indigo pulsar]

https://paste.pythondiscord.com/acomeyetuc.rb

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

and the main

don't get attention to indentation, it's good

[indigo pulsar]

So the incrementation of Y works if I press away D or Q but normally the carater is able to jump without press away

[indigo pulsar]

Ok i found the part which talk rubbish

but how can I detect if any keys is pressed ?

isn't pressed*

[indigo pulsar]

OH MY GOSH

I fixed it

here we are

[finite briar]

if keys[pygame.K_(insert key here, UP, DOWN, LEFT, and RIGHT are the arrow keys. letters are lowercase. other specific buttons are all in caps.)]```

[finite briar]

you dont need parenthesis around the button though, for up it would look like py keys = pygame.key.get_pressed() if keys[pygame.K_UP]: alkdoasnmdoasn

Nuke_rotated,Nuke_rotated_rect = rotate(Nuke,angle)
screen.blit(Nuke_rotated,Nuke_rotated_rect)
return rotated_surface, rotated_rect```
can somebody break these down for me please? ;-; its three seperate commands but i dont know how you'd do two variables for a function? and when you blit it why do you blit two things? and when you return, the same thing ;-; how do u do it with two things?

[finite briar]

DAMNNN THATS A NICE GRAPHIC-

How'd ya do it? 😉 you know u wanna tell me 🙂

:p

[indigo pulsar]

I will give the code and maybe publish on github

Now need collision, plateform

I think i will read a text file to parse the environment map

[finite briar]

me over here having trouble just rotating my image* right, r i g h t.

[indigo pulsar]

Pygame.transform.flip()

[finite briar]

i meant rotate as in literally rotate lol like 45* or something :p thank you though

[indigo pulsar]

My bad 😂

[indigo pulsar]

So pygame.transform.rotate()

[finite briar]

I'm trying to learn how to use rotozoom but like i suck at using functions ;-; also rotate would increase it a certain amount, rotating it by an increasing interval like angle += 1 would make it crash if you carry it out for too long, but rotozoom is different; ```py
import pygame
from Colors import *
middle = 300, 300
whole = 600, 600
def rotate(surface, angle):
rotated_surface = pygame.transform.rotozoom(surface, angle, 5)
rotated_rect = rotated_surface.get_rect(center=middle) # 300, 300
return rotated_surface, rotated_rect
pygame.init()
clock = pygame.time.Clock()
screen = pygame.display.set_mode(whole)
Nuke = pygame.image.load("C:\Users\Felix Laptop\Downloads\Spaceship1.png")
Nuke_rect = Nuke.get_rect(center=middle)
angle = 0
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
angle += 1
screen.fill(purple)
Nuke_rotated,Nuke_rotated_rect = rotate(Nuke,angle)
screen.blit(Nuke_rotated,Nuke_rotated_rect)
pygame.display.flip()
clock.tick(30)

i dont quite know how to use that as i said, I'm confused about a few things :p but I'm on the verge of understanding it... i think ;-;

[indigo pulsar]

Why there is a nuke_rotated_rect ?

[finite briar]

i think its for the get_rect

[indigo pulsar]

but the nuke_rotated_rect will do what ? take a part of the surface nuke_rotated ?

[finite briar]

uhm I'm not entirely sure myself but i think its used to set the reference point for the previous angle?

[indigo pulsar]

what you want to do ?

with your code

[finite briar]

I want to rotate it in circles by a specified amount without* it crashing, but not instantly so it makes a turning animation

You're overwriting the filename variable when you load the image
Maybe you can store them in a dict?

Theoretically, but it'd probably not be a very good idea.

There's panda3d and pyglet for 3d engines, IIRC.

This is my first day using pygame so don't judge
I am attempting to make a platformer, am on a beginner level and the arcade library looks like something I should use. Should I? I just checked the pins and it looks quite good

@frozen knoll Is the arcade library more user friendly for beginners? I want to make a platformer which has background music, coins and enemies. By the way sorry for the ping. It looks easier so I think I will ditch pygame...

[frozen knoll]

Both Pygame and Arcade are fine. I'm biased, but I do think Arcade is easier. The platformer tutorial ought to get you started.

i'm making a 2d platformer with pygame and i'm making the level layouts from text files made of numbers

you know, 0=air, 1=dirt, 2=grass and so on

do these things have a name?

like, what are these number text files called for level layouts

game maps?

tile maps?

I'd like to know because that would really help me with searching for tools that allow me to make level maps more easily

[tranquil girder]

tilemaps
Tiled is a common one
LDtk is also very cool and probably what I'd choose myself
Using images (.png) is also a good solution. You can jut edit them in Paint of Photoshop

[grim abyss]

is anyone in here familiar with computing points from a "world-space" to a "screen-space" ?

a translation rather...

[potent ice]

Depends in what context

[grim abyss]

@potent ice I have a list of Points whose X,Y values range from -65k - 65k and I need help translating them to a 640x480 canvas...

[potent ice]

So [-64.000, 65_000] (X) should be projected from 0 -> 640 ?

Also, is this 2D or 3D? (assuming 2D because you only mentioned X and Y)

[grim abyss]

2d

[potent ice]

Are you using some kind of graphics library or are you just calculating the values

[grim abyss]

I'm using the "planar" geometry lib

[potent ice]

hmm their docs only link to some ad farm site advertising for online gambling?

Link to the library? I might have found the wrong one. I would hope the library have a system for projection

[grim abyss]

https://pythonhosted.org/planar/

[potent ice]

Ok. I guess they have to update their README : https://pypi.org/project/planar/0.4/

all the links are wrong and their old domain was hijacked by ad spammers 😄

Can't you just do some manual projection on those points?

The typical way of doing that is to normalize the points to be [-1.0, 1.0]

[grim abyss]

What exactly does it mean to "normalize" the points?

[potent ice]

Just divide them by 65000

[grim abyss]

https://github.com/InZane84/WADdle-Plot-CLI Line 296 is the function that pertains to what I am asking....

[potent ice]

Then you multiply them up + adding an offset to make them fit into the screen

[grim abyss]

It would really help me if you could modify that function to do it so that I can see how it works in code...

[potent ice]

No time for that, but I can try to make a function to convert the coordiantes

[grim abyss]

ok cool

[potent ice]

Something like this maybe```py
from collections import namedtuple

Point = namedtuple("Point", ["x", "y"])
SCREEN_WIDTH, SCREEN_HEIGHT = 640, 480
ASPECT_RATIO = SCREEN_WIDTH / SCREEN_HEIGHT

points = [
Point(-65000, -65000), # lower left
Point(-65000, 65000), # upper left
Point(65000, -65000), # upper right
Point(65000, 65000), # upper right
]

for point in points:
projected_point = Point(
point.x / 65000 / ASPECT_RATIO * SCREEN_WIDTH / 2 + SCREEN_WIDTH / 2,
point.y / 65000 * SCREEN_HEIGHT / 2 + SCREEN_HEIGHT / 2,
)
print(point, projected_point)

That should take aspect ratio into consideration as well (assuming screen width > screen height)

Probably better functions to do the math in the library itself

This is pretty similar to what an orhogonal projection matrix would do

[grim abyss]

interesting, i'm going to see if I can get this function to work...

[potent ice]

Can make it into a function that takes the "viewport" parameters

right now we're just relying on some imaginary screen size

The 65000 values could also be parameters so you can project using a different system

In computer graphics (on gpus) we normally do this with projection matrices (imaginary code) ```py

Crate a projection matrix that converts our points into normalized device coordinates.

Normalized device coordinates is [-1, 1] on X and Y.

The surface we are rendering to operates on this system.

This is a 4x4 matrix

projection = Mat4.orthogonal_projection(
-65000 / ASPECT_RATIO, 65000 / ASPECT_RATIO, # Range on x axis to project to the sceeen
-65000, 65000, # Range on y axis to project to the screen
1, -1, # Depth (depth range. Can normally be ingored)
)

projected_point = projection * point # Assuming the point is a vec4

The screen coordinates are [-1, 1] on x and y normally with gpu based rendering so the projection matrix is converting our coordinate system into the screen coordinates (also called "normalized device coordinate)

The math for doing this in 2D is a whole lot simpler, thankfully!

yes, this is 2d

[potent ice]

Might be a more flexible way```py
def project_to_surface(point, left, right, top, bottom):
# Fit this to the screen.
# left, right, top, bottom is the coordinate range that will be diplayed in the screen
return new_point

projected_point = project_point(point, -65000, 65000, -65000, 65000)

and it could take a screen width and height as well?

It depends what you need

Can be easier to sketch down with pen and paper first. At least I find it useful.

[grim abyss]

ok on i'm going to work on this. thanks. I'll let you know how it turns out

[potent ice]

It's really just 2d vector translation and scaling. Can probably use functions in the library

just that things need to happen in the right order

Possibly even simpler to make it into some class you can pass around if you need several different projections

combine that with prepared 2D bounding boxes (min_x, min_y, max_x, max_y) for each set of geometry to make things auto fit to screen

[grim abyss]

the bounding boxes. how do I project into a bounding box?

[grim abyss]

as you can see, the planar lib seems to provide everything needed. I can't seem to "project" the points inside a bounding box though...

I had even thought of that. Create a bbox from the screen dimensions and plot the points within it...

[potent ice]

The bounding box I talked about was the min/max position for a group of points

But you can of course define some box these points should be projected to on the screen

That would probably be called a "viewport" or something similar

"Project the coordinate system -65000, 65000, -65000, 65000 onto a 100, 100 viewport on the screen"

can anyone help me with a random number generator for my game. im trying to make a tic tac toe type of thing and make it so the generator stores the number and the number it picks is the spot it goes is there anyway to do this. i have the random gen done i just need help getting it stored and putting it on my spot

[grim abyss]

@potent ice is there a 'lite' library for doing this math? If I get away from Planar it would probably help me out ...

https://pythonhosted.org/planar/vectorref.html I see under "normalized" it returns a vector scaled to "unit" length but where is the "unit" length specified?

are there any methods in particular in that link that pertain to this?

Can I use that?

[potent ice]

normalize and project can mean different things

[grim abyss]

project(screen_dimensions) for a point?

[potent ice]

Look up the math and see if it makes sense. I don't know the library 🙂

[grim abyss]

and I don't know the math, lol

else I would be wayyyy past this and done with this application...

[potent ice]

Here's what I do: Draw things out with pen and paper can you can makes sense of things even with little math experience

You don't have to convert your points into the [-1, 1] system first. I just find that simpler because I am used to it

[grim abyss]

what's a one liner to do that? say I have a list of points...

for p in points:
  p.normalize()

[potent ice]

That's probably normalizing a vector to have length 1? Doubt that is even remotely useful for this

You can get away with only translation and scaling

[grim abyss]

should the arg to scale be ((640, 480))?

in fact I've tried that and it doesn't work but maybe I had the order in which I was multiplying by wrong

• scale * offset or?

is the order of multiplication wrong?

[potent ice]

Probably wrong order. Much easier if you build a simple example like I originally created

Define the corner points and see if they are transformed correctly

Take one step at a time

You probably want to translate the points so that the lower left corner is 0, 0 first

then you can scale that to the screen size

Then possibly you have to take aspect ratio into accunt

but.. do it in smaller steps. verify each step in the calculations by printing them

[potent ice]

https://pythonhosted.org/planar/transforms.html#affine-transforms looks promising

[grim abyss]

I'm using those although maybe incorrectly...

[potent ice]

is bbox.center in local or global coordinates? You might want to check that

[grim abyss]

vertex_vectors are the raw points from the level data...

that's setting the Affine translation to the center of the map

I can draw the map centered but I can't compute the scale on a map by map basis...

so I also need to compute the CORRECT scale for each individual level I'm plotting...

[potent ice]

why separate scale for each point?

[grim abyss]

hmmmm.....idk

[potent ice]

things will be scaled based on where 0, 0 is

translate the point first and scale after

[grim abyss]

I've read through that several times. It would of been helpful if they would of actually used a library to plot something using their Planar library...oh well

Eventually, I will figure this out...

yeah I'm translating first then scaling

[potent ice]

It's probably just something stupid. I aways is. Like I said: I would make a separate small script and play around with things printing every step

Define 4 test points defining corners in a bbox at first and see how they are transformed

Verify everything by printing it out

[grim abyss]

sounds logical enough...

[desert forge]

any 3d api for python?
