game-development

[dawn quiver]

i am a beginner

i want to get into game development

[glass sonnet]

@dawn quiver you could try this tcod roguelike tutorial: http://rogueliketutorials.com/tutorials/tcod/v2/ Some python knowledge is recommended but not strictly required. Also check out the pins here. https://inventwithpython.com/invent4thed/ seems like a good place to start.

[frozen knoll]

@steel wing Check out https://Arcade.academy

Also @dawn quiver . Might help get you started. Lots of examples and tutorials.

[cloud nest]

what do i need to study before i get to game dev?

[dawn quiver]

@cloud nest

1. a programming language
2. MATH!

[cloud nest]

can you explain more in detail?

[dawn quiver]

@cloud nest
consider this example:

1. I wish to create a basic Mario-styled platformer game! I need to study a programming language and its basics. Suppose i use Python to make it. First i need to master the basics of python. Then i learn a game library like Pygame (in Python for instance). I use resources on the internet to do that!

2. finally, i need MATH. I need at least high school math for this. Math, is for making you character move, calculate his jumps, and calculate collisions with Objects, also much more, like calculating fireball throws.

3. Optimizations! - You just cant publish a buggy game can you? You need to optimize it by getting to make it smoother. Optimizations may include increase in the device's processing power, or formatting your code better.

@cloud nest

[restive lantern]

The math depends on what tipe of mechanics you want in your game

[dawn quiver]

not really. you need math at every point in the game. even in drawing objects

You cant just go about drawing objects anywhere! you need to know about the cartesian coordinate plane!

[restive lantern]

But thag is too easy
You are scaring this guy saying mathematics like if it was super complex stuff

[dawn quiver]

he needed detail

half knowledge is far deadlier than no knowledge

[restive lantern]

@cloud nest
Look bro just start with pygame or arcade. Do some simple stuff and then you can get into the mathematics one step at the time

[dawn quiver]

then get stuck with math.

[restive lantern]

Just dont get this guy discouraged with math. He can make it

[cloud nest]

for now, i think i just need to learn the basics

[cloud nest]

im kinda gifted with math

[dawn quiver]

therefore its better to ask @restive lantern

not everyone is bad at math i guess.

[restive lantern]

Look im awfull at math and im still making it

[dawn quiver]

nice.

you cant go too far with basic math, you see.

[restive lantern]

Usually the guys that are intrested in making games are gamers and i think that the gamer are usually the guys that dont care about maths but who knows

[cloud nest]

can i tag you again sometime?

[restive lantern]

Ok

[odd cypress]

how do we get out of pygame infinite loop
whenever i click the pygame x button it says not responding

[crisp junco]

import pygame
pygame.init()
#[...] some part of code here

while True: #loop 
    for event in pygame.event.get():#List of events like mousepress,keydown etc.
        if event.type == pygame.QUIT: #Check if 'X' button is pressed
            break #Exit the loop
    pygame.display.update()

pygame.quit() #De-initialize pygame
sys.exit() #Exit

[odd cypress]

does hovering of mouse come under events

[crisp junco]

yeah

[odd cypress]

jus a min ill get back to u

[crisp junco]

👍

[odd cypress]

i dont know how to explain my problem

im actually doing a project

we are almost donr

done*

but this one is troubling

its a hobby project

[crisp junco]

what's the problem @odd cypress ?

[odd cypress]

basically to start the program running, we wait until the event is mousebuttondown

as soon as mousebuttondown is captured, i create a loop for checking the events eithin this

within*

[crisp junco]

import pygame
pygame.init()
#[...] some part of code here

while True: #loop 
    for event in pygame.event.get():#List of events like mousepress,keydown etc.
        if event.type == pygame.MOUSEBUTTONDOWN: #Check if mousebutton is pressed
            #[...] Your code here
    pygame.display.update()

pygame.quit() #De-initialize pygame
sys.exit() #Exit

[odd cypress]

hey wait some ideas are striking me rn

get back to u later after some time

[crisp junco]

alright

[unreal river]

k

@crisp junco did you solved your problem?

[crisp junco]

which problem?

[unreal river]

the error on your code

[crisp junco]

What are you talking about?

@odd cypress was having a error in his code not me

[unreal river]

oh

wrong one HAHAHHA

[crisp junco]

I was helping him

[unreal river]

sry

[crisp junco]

lol

np

[unreal river]

@odd cypress can you give me the error?

[odd cypress]

basically when the game is running if im trying to click on close button it says not responding

[unreal river]

did you save it?

[odd cypress]

@crisp junco shall we have a discord screen share meet

[crisp junco]

Didn't you see the code that I provided you?

[crisp junco]

this one

[odd cypress]

i checked but there are some problems which im not able to explain

[crisp junco]

What's your code?

[unreal river]

just copy the error

[odd cypress]

while running:
for i in range(0, 3):
screen.blit(image, rect)
pygame.display.update()
pygame.time.delay(250)
screen.fill((255, 255, 255))
pygame.display.update()
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.MOUSEBUTTONDOWN:
mouseX, mouseY = pygame.mouse.get_pos()
print(mouseX, mouseY)
A1 = Ant(mouseX, mouseY, (0, 0, 0))
move(A1)
while event.type != pygame.QUIT:
showSteps(A1)
# modified the available screen area according to the counter frame
if A1.AntX in range(0, 251) and A1.AntY in range(0, 71):
break
elif A1.AntX < 799 and A1.AntY < 599:
move(A1)
else:
break
running = False
pygame.display.quit()
pygame.quit()
else:
pass

[unreal river]

kk

try break instead of running = False

[odd cypress]

please see my code

[unreal river]

is it supposed to be if you pressed your mouse then it dose all of the things? is it the indentation?

[odd cypress]

yes

[unreal river]

then the pygame quits?

[odd cypress]

yep if it does not satisfy any of the given conditions

@crisp junco are u there?

[unreal river]

try something like ```py
mouse_pressed = pygame.mouse.get_pressed()
if mouse_pressed[0]: # Checks if the mouse left button is pressed

codes here!

[odd cypress]

@unreal river ??

[unreal river]

sorry thinking

[odd cypress]

ive done same only right/....

[unreal river]

?? wdym

[odd cypress]

this is same as my logic right

[unreal river]

oh i get the code

[mortal herald]

why it say the "running" is wrong?

[unreal river]

see your creating a while loop without ```py
for event in pygame.event.get():
if event.type == pygame.QUIT:
# CODE HERE

the second while loop

[odd cypress]

oh the same event is being tested

so how do i change it

[unreal river]

while running:
    events = pygame.event.get()

    for i in range(0, 3):
        screen.blit(image, rect)
        pygame.display.update()
        pygame.time.delay(250)
    screen.fill((255, 255, 255))
    pygame.display.update()
    for event in events:
        if event.type == pygame.QUIT:
            running = False
        elif event.type == pygame.MOUSEBUTTONDOWN:
            mouseX, mouseY = pygame.mouse.get_pos()
            print(mouseX, mouseY)
            A1 = Ant(mouseX, mouseY, (0, 0, 0))
            move(A1)
            while event.type != pygame.QUIT:
                events = pygame.event.get()
                showSteps(A1)
                # modified the available screen area according to the counter frame
                for event in events:
                    if event.type == pygame.QUIT:
                        #CODE HERE
                if A1.AntX in range(0, 251) and A1.AntY in range(0, 71):
                    break
                elif A1.AntX < 799 and A1.AntY < 599:
                    move(A1)
                else:
                    break
            running = False
            pygame.display.quit()
            pygame.quit()
        else:
            pass

set a variable that stored the pygame events

set the variable on the first loop and then do the same in the second

[mortal herald]

it says "NameError: name 'running' is not defined"again!

[unreal river]

?

[unreal river]

that happened to me also

you can set the running variable in a class and create an object that is part of the class and it will be defined

[odd cypress]

im not getting ur point

can you alter it further

[unreal river]

class Game():
  def __init__(self):
    self.running = True

game = Game()
while game.running:
  #CODE HERE

[unreal river]

while running:
  events = pygame.event.get()
  for event in events:
    if event.type == pygame.QUIT:
      pygame.quit()
    if event.type == pygame.MOUSEBUTTONDOWN:
      while True:
        events = pygame.event.get()
        for event in events:
          if event.type == pygame.QUIT:
            pygame.quit()

define the variable in the loop and store the pygame events in it

its like the for event in pygame.event.get()

except its in a variable

@odd cypress ```py
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
elif event.type == pygame.MOUSEBUTTONDOWN:
while True: # Cant get to the if statement below because this keeps looping

[untold moat]

Just wondering

Is functions highly useful for game dev

[crisp junco]

super useful

[crisp junco]

it's not just about game dev, it highly useful in every area

[odd cypress]

can you please explain y u have told to do that way or ewhat is wrong with my approach? @unreal river

[unreal river]

I help though :v

[odd cypress]

what

i still get it

did'nt

its the same

[unreal river]

bro your second while loop doesnt check if you click the X button on the top right

[odd cypress]

can you edit in the main code that i have sent here

@unreal river

[unreal river]

DM me the full code

[odd cypress]

ok bro

[dawn quiver]

just do this:
if event.type == pygame.QUIT: pygame.quit()
further you can add exit() after pygame.quit() if it still doesnt quit.

@odd cypress

pygame.quit() simply quits the pygame window if the X button is pressed. pygame.QUIT is the event for pressing the X button.

[odd cypress]

thanks for info

does anyone know how to increase pixel size in pygame?

[odd cypress]

anyboddy??

[cloud nest]

can you briefly explain what code formatting is?

[worldly flare]

hey! i am trying to make a boss ai if anyone has created one then plz guide me

also the game I am making is a dungeon crawler so I want to make random maps with procedural generation IDK hw to archieve that so please help me with that.

[odd cypress]

if we ask in correct group, u ppl wont reply
if we ask in multiple grps , u ppl call it spamming

[olive parcel]

Maybe you should ask your question more clearly. I have no idea what "increasing pixel size" is supposed to mean.

[torpid silo]

Starting from pygame 2.0, you can use the SCALED parameter to pygame.display.set_mode

[worldly flare]

yeah right

I suffered from this

[olive parcel]

If people in the correct channel don't know the answer to your question, what makes you think that people in an entirely unrelated channel will know it?

It's like if you entered your local hairdresser shop and told them "My greengrocer doesn't have any carrots, do you have any?"

[worldly flare]

but I am asking for the right stuff in the right channel!

[blissful folio]

I would have made a list of things the boss can do like jump, shoot, etc. Then have python randomly pick them from the list.

[olive parcel]

I was addressing @odd cypress

[worldly flare]

So I am asking my hairdresser for cloths not for some fricking carrots

[worldly flare]

its actually same

to whoever u said

[worldly flare]

kinda good thought

[olive parcel]

So confusing when people change their nickname mid-conversation…

[blissful folio]

Well first thing number of askers would always be greater than the number of persons who answer. So maybe just ask in one channel then try to bump the question rather than just type the whole question everywhere all the time.

[odd cypress]

can you please send a sampke cose

sample code*

or the way u write that

[torpid silo]

pygame.display.set_mode((640, 480), FULLSCREEN | SCALED)

will make a fullscreen program with everything scaled up

so you draw to the screen as if it was 640x480, even though it's however big your monitor is

[odd cypress]

scaled not defined

[torpid silo]

pygame>=2.0.0

right?

[odd cypress]

im actually inverting pixel colors

im on pycharm

how to checj version

check*

of pygame

[torpid silo]

I've never used pycharm

do you use pip?

[odd cypress]

yes

pycharm --version?

[torpid silo]

just do pip install -U pygame

[odd cypress]

oh kk

[torpid silo]

Also, https://www.pygame.org/docs/ref/display.html#pygame.display.set_mode <-- docs for SCALED

[odd cypress]

thank u doing it, pls dont leave ill get back to u if i have problems'

i was unable to terminate the program in this mode

and the pixels are not enlarged

only the screen is enlarged

please help me with pixel enlarging @torpid silo

guys ayone pls help me, i hope im asking in the right grocery shop

[blissful folio]

Can you explain what you mean by enlarging pixels?

[ionic tundra]

you could do pygame.transform.scale and pass in the sources surface, the pixel size u want the display to be enlarged to, and the destination surface as arguments

That should do the trick ig

[elfin frost]

I want to make a fighting game. Where do I start?

[true basin]

from random import randint

#set player to True
for i in range (3):

t.append("win")
else:
print("That's not a valid play. Check your spelling!")
#player was set to True, but we want it to be False so the loop continues
def result():
if int(t.count("win")) >= 2:
print (" YOU DID IT! YOU WON!")
else:
print("YOU LOST!")

result()

this is my code where can i put in a parameter

[elfin frost]

yes

[true basin]

nah like where can I add one into there

[gilded grove]

do you know what a parameter is?

[true basin]

sorta

[gilded grove]

what is it then?

[true basin]

i think issa variable sorta idrk

[gilded grove]

def list(a_list):
  for val in a_list:
    print(val)


print(list([1,2,3]))

what do you think happens when that code is run

[true basin]

not sure

[gilded grove]

well it prints 1, 2, 3, then None

and a_list

is a list

that is a parameter

[true basin]

ah

[gilded grove]

have you read automate the boring stuff

[true basin]

nah im new to coding im taking a this class in hs

I havent read it

well

it's a free e book

and it also explains stuff better than I can

[true basin]

I see

[gilded grove]

it will make learning the basics much easier

and it gives concrete examples too

[true basin]

Ill check it out

Do you think you could give me an example real quick tho of how i could use a parameter in the rock paper scissors tho

[gilded grove]

you could have a function that takes strings from both players

and then just put a shit ton of if elif conditions

[true basin]

aight thanks bro

[gilded grove]

if this player chose rock and this player chose scissor

then the player that chose rock won

what is best(most optimised) in pygame to code a game like pokemon ?? i thinking to use tiled to make the map and import it as csv and blit it onto a Xscreen ,and some sort of camera that will crop the Xscreen and display it on the displayscreen depend upon the player position ................

guys in this the second while loop has a for loop to check if user quits in between the game or not

it works fine

but i have a doubt

if we click on quit button
doesn't it break out of for loop and continue with while loop statements

please clarify this guys

[blissful folio]

Yes it should

But it doesn't because you are setting running = False whent the event == pygame.QUIT

Hi all, why would people choose to use pygame over game engines?

[cyan furnace]

pygame has great librarys and makes it easy to define screen, sound, and button imputs

[mystic lodge]

is there anyway to use pypy to compile python programs and if so can it compile with modules such as pygame?

[restive lantern]

im also looking for this

[gilded grove]

a physics engine???

[gusty wave]

does anyone know a documentation on pygame ui?

[restive estuary]

Yes

[gusty wave]

or a tutorial

[gusty wave]

what is it then?

[restive estuary]

Basically we may need to build pygame in tkinter or pygui

[gusty wave]

tkinter

is there a tutorial?

pls

[restive estuary]

https://youtu.be/wMrdLvWSl_o

You can make a game only with tkinter

No need of pygame

[gusty wave]

ok

I am using pygame rn

I need a ui that can display a message

with pygame

if it can be imported into a pygame script

then I will use it

@restive estuary

[restive estuary]

@gusty wave you may use
https://pyimgui.readthedocs.io/

[gusty wave]

does it work with pygame?

[restive estuary]

S

[gusty wave]

?

[restive estuary]

Short form of yes

[gusty wave]

ok

[restive estuary]

Bye

[gusty wave]

is there a tutorial on yt?

[normal silo]

https://github.com/MyreMylar/pygame_gui

[gusty wave]

is there any ui stuff in the pygame package?

[normal silo]

What do you mean?

[gusty wave]

like making gui

with just pygame

no like pygame_gui

or anything like that

[normal silo]

If you want to make it with just pygame, then just do that.

[gusty wave]

yeah

IDK how to do it

[normal silo]

Do you know how to do collision detection between a point and a rectangle?

[gusty wave]

no

I just need text

thats all

[normal silo]

Just text? Then just render text, pygame has that.

[gusty wave]

YES

IDK HOW TO DO THAT

[normal silo]

https://pygame.readthedocs.io/en/latest/4_text/text.html

It's the first search result on google for "pygame text"

[gusty wave]

ok

ty

um

uh

[restive lantern]

Where it says none in the first line you have to put a font file

[gusty wave]

what font should I use?

[restive lantern]

You can put something like "Arial.ttf"

Ttf extention is a font file

[gusty wave]

ok

what about this

[restive lantern]

The 24 is the size of the text

[gusty wave]

yes

ik

[restive lantern]

In the second line 'hello' is the text to be rendered

[gusty wave]

ik

but the Blue and Screen

appear to be an error

[normal silo]

Using None will load the default system font.

[restive lantern]

Blue is a color and the way pygame handles color is using a tuple like
Blue = (0,0,255)

[gusty wave]

\

[restive lantern]

The color is in rgb (red,green,blue) and in the tuple you have to choose a value between 0 amd 255 for each color

[gusty wave]

ok

ik

[restive lantern]

The screen in the last line is the surface where you want to display the text img

[gusty wave]

BRO

can you just help me

like

show an example

how how the code should look like

    font = pygame.font.SysFont("Arial.ttf", 24)
    img = font.render('hello', True, BLUE))
    screen.blit(img, (20, 20))

the blue var

is some where else

in my code

BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
GRAY = (200, 200, 200)

[restive lantern]

is above the text piece of code

[gusty wave]

wdym

[restive lantern]

just wait and i will make you an example

[gusty wave]

screw it
BLACK = (0, 0, 0)
RED = (255, 0, 0)
GREEN = (0, 255, 0)
BLUE = (0, 0, 255)
GRAY = (200, 200, 200)

font = pygame.font.SysFont("Arial.ttf", 24)
img = font.render('hello', True, BLUE))
screen.blit(img, (20, 20))

[restive lantern]

yea like that

[gusty wave]

you can now make an example of how the working version of the code should look like

[restive lantern]

screen = pygame.display.set_mode((700,400))

blue = (0,0,255)

font = pygame.font.SysFont("Arial.ttf", 24)
img = font.render('hello', True, blue))
screen.blit(img, (20, 20))

EZPZ

[gusty wave]

no ezpz

[restive lantern]

what is wrong?

[gusty wave]

are you blind?

the blue is an error

the font is an error

img = font.render('hello', True, blue))
^
SyntaxError: unmatched ')'

[restive lantern]

there is an extra parenthesis right after the blue

in the img line

[gusty wave]

wdym

[restive lantern]

img = font.render('hello', True, blue)<--)

[gusty wave]

oh

display.blit(img, (20, 20))
AttributeError: 'tuple' object has no attribute 'blit'

[restive lantern]

let me look up

display variable is being treated as a tuple

not a surface

[gusty wave]

then uh

how 2 fix

    pygame.init()
    display = (1200,900)
    pygame.display.set_mode(display, DOUBLEBUF|OPENGL)

[restive lantern]

it should look like this
display = pygame.display.set_mode((1200,900), DOUBLEBUF|OPENGL)

this line returns a surface

[gusty wave]

gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)
TypeError: 'pygame.Surface' object is not subscriptable

[restive lantern]

but you are defining display as a tuple

send text

[gusty wave]

    gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)
TypeError: 'pygame.Surface' object is not subscriptable

    pygame.init()
    display = pygame.display.set_mode((1200, 900), DOUBLEBUF | OPENGL)

    icon = pygame.image.load("assets/icons/logo.png")
    pygame.display.set_icon(icon)

    gluPerspective(45, (display[0]/display[1]), 0.1, 50.0)

    glTranslatef(0,0, -10)

    glRotatef(25, 2, 1, 0)

[restive lantern]

in display[0] and display[1]

you cant do that

you only do that for list or tuples

and display is not a tuple

[gusty wave]

???????????????????????????????????

I am confused

[restive lantern]

gluPerspective(45, (---->display[0]/display[1]), 0.1, 50.0)

just use 1200 and 900

or put those two in a variable

[gusty wave]

confused a lot lot m

[restive lantern]

gluPerspective(45, (1200/900), 0.1, 50.0)

like that

[gusty wave]

pygame.display.update()
pygame.error: Cannot update an OPENGL display

[restive lantern]

i cant help you with that since i dont use openGL on my stuff

let me see

display = pygame.display.set_mode((1200, 900), DOUBLEBUF | OPENGL) <--change this line for:
display = pygame.display.set_mode((1200, 900))

[gusty wave]

can you just give me a stupid tutorial?

[restive lantern]

do you know about indexes in lists and that stuff?

[gusty wave]

omg

[restive lantern]

tell me do you know?

[gusty wave]

idk

[restive lantern]

looks like you need to learn a little bit more than just pygame

no. you cant. that is why the channel is #game-development .

[teal ember]

what would be the best way to fit the tile image on the whole window?

should i resize or draw multiple tiles from a loop

[sacred trout]

Depends what you are using, but assuming it is pygame, a for loop seems to be the best
nice rounded corners btw ! what wm is this ?

[teal ember]

i3 gaps

used picom (git version) for the rounded corners

so ye a for loop works thanks, thought it would have performance issues but i dont seem to have any

[shrewd copper]

Has anyone noticed an issue of their sprites getting slightly distorted while moving diagonally in pygame?

or is that just me

I wonder if it's due to the fact that it's moving quicker diagonally.

[gusty wave]

does pygame have cross-platform support?(mobile, console)

[half pasture]

well it'll run anywhere where python can run i think, try searching for python libraries that allow you to tanspose your code to different platforms

[fathom thunder]

anyone have a reccomendation on how to start game development for python? I want to start off fresh and want to know everything about python and game development, and would be nice if you could send me a playlist on youtube or a video on everything about python

[prisma cypress]

learn the language first, you can probably find videos on youtube from freecodecamp, and game development is honestly just about how you can understand the module you are using, and how everything works together.

each software isn't easier or harder, it's a different can of worms

[dreamy holly]

hello everyonehello everyone
how can i create perspective view custom in the game ?

in every 3d games

inject py file to games and making custom camera ...

[serene kettle]

I am new , what game should I make first

[worldly flare]

what is hardware accelerated rendering

[worldly flare]

dude what framework are u using

?

[worldly flare]

are u using python

and the art is amazing

[gusty wave]

Unity or Unreal Engine

they both have support(but hard to add and use)

I wouldn't use python for game/engine development

I would most likely use something like C/C++ or Java

maybe even C#

[left skiff]

and if you want to use python, try Kivy, Pygame, Panda3D, Arcade, Pyglet, Cocos2D, Pyxel, Wasabi 2D, Ursina, PursuedPyBear

[dawn quiver]

python is not suitable for large game development right??

[olive parcel]

It is

@dawn quiver some large games like EVE Online, Toontown, Pirates of the Caribbean Online, and several others have been made using Python.

I think Civilization IV also is made with a lot of Python.

[dawn quiver]

not Assassin's creed or Death stranding or Red dead redemption, these aaa titles are far too complex for python only

but majority of it is made using c# c+ right?

[olive parcel]

The underlying engine for those games will be written in something like C/C++, but the higher level game logic and scripting can be done in Python

I'm reading here Battlefield 2 uses Python as well

[dawn quiver]

hmm, intresting

[olive parcel]

A good approach is to start prototyping and writing the game in Python, and if parts of it become slow, you can rewrite the slow parts in C/C++

Or to pull in a C extension from PyPI to speed up those tasks

[fair panther]

can someone tell me a good book to learn pygame?

[next estuary]

I'm working on a platformer with snow elements, I don't have a good idea for gameplay though. See vid for gameplay.

[prisma cypress]

i might be kinda stupid but i'm new to this in general, how would you load an image file on python, where do you store it?

[next estuary]

import PIL
image=PIL.Image.Open("file_path")

the lowercase image now holds the loaded image

[prisma cypress]

ok, thank you!

where can i find the download for the PIL module though?

[severe saffron]

you would install it with pip

either PIL or pillow, pillow being the more modern and almost always better version

[prisma cypress]

ok, i couldn't find PIL to install using the standard: py -m pip install (name)

[tawny sky]

Omg the game looks fantastique. Are u using pygame??

[next estuary]

Yeah pygame and numpy for the snow :)

[stoic swan]

You could also use the in-built tkinter module to create a window with the image

Never done it before but I know it's possible

[manic seal]

i am trying to import some old game's animation into blender but i can't get them to work since i don't know how to manipulate quaternions

( image 0 are the values i believe to be the quaternion rotation of one of the leg bones )
( image 1 is what the armature looks like when applying these rotations to the leg bones )
( image 2 is legs and arms )
( in image 3 we can see that clearly something is inverted, the left and right arms have 'switched places' )
( image 4 is the armature with most* bones rotated, note that the character is now facing the opposite direction )

i don't know if the problem is with the quaternion value or with the armature itself since it was imported using a blender addon

i also don't know how to correctly manipulate the quaternion to fix it if it is at fault

[near widget]

@normal silo Why Ursina?

[normal silo]

Ursina is a lot like processing: https://processing.org/

It just has everything setup for you. And Ursina already has an entity system making things very convenient.

I also want to be able to add shaders as I please, which it lets me do.

[near widget]

I know processing and funnily it was not my introduction to graphics - that was Python, when I was making the rendering engine with this guide - https://github.com/ssloy/tinyrenderer/wiki. Good times, it was slow as hell 😄

[normal silo]

I just throw the slow parts into numba.

[near widget]

I found that later too! I still think that it is an awesome project!

I wanted to rewrite everything to CUDA then 😄

[normal silo]

My first software renderer was in C, I actually could not be bothered to deal with the OS windowing (annoying, though I know it now more than I want to), so I just rendered it in the terminal (ascii).

[near widget]

I must go, it's really late here (GMT+2), but I will probably be here tomorrow, see ya!

[next estuary]

I got multi-layer parallax working in numpy / pygame 🙂

It's more apparent when there's an x vector on the snow

[iron sierra]

Guys can i make a game like fortnite or minecraft with its graphics by pygame or no???

[teal ember]

i dont think pygame would do much good when it comes to 3d

check out panda3d or ursina

[iron sierra]

ok can panda3d or ursina make a game like fortnite??

or i need to use game engine like unity??

[teal ember]

also, other languages and game engines are better for 3d game development, but python would be almost ok i think

fortnite is a pretty big game

[iron sierra]

do u mean python is for small game

[teal ember]

tbh, i have not done any 3d game dev in python so i am not sure if it is possible, but its sure gonna be harder than using some game engine which has a lot of more features

[teal ember]

these days you can make pretty big games in python, especially in the 2d field

but its not the best choice when it comes to 3d

[iron sierra]

ok ty so much

[teal ember]

you still can try out panda3d, there are a good amount of 3d games made in python

[iron sierra]

ok

[near widget]

Well, EVE Online is written in a variant of Python, so I really wouldn't worry myself about the language that much.

I don't want to preach the Nike ideology, but starting and doing seems to be the best languages, at least for me.

[potent ice]

It requires a lot of commitment to learn 3D properly. It's a very complex area. If you can start playing with that using higher level tools.. good!

[normal silo]

The best option for a large 3D game with python is using Godot with python support.

You can then also use C++ if needed.

But you can get decently far with panda3D / Ursina and something like numba or cython.

You can make something like minecraft, but you will have to do many parts in cython or numba like terrain mesh generation.

And enemy AI (path finding).

Godot will have many things already implemented in C++ (there are modules made by others that you can download for stuff), so you can just script some of the game logic in python on top of that and in that case python's speed won't matter much.

https://github.com/Zylann/godot_voxel could be used, and may be faster than minecraft java edition.

[elfin frost]

is ursina still good for 3d game? 3d building

[proven kayak]

So does pygame have professional-level potential? Like, are there any big games out there that use it?

and i have done everything right sooo

i dont know where i am going wrong

[potent ice]

pygame.rect != pygame.Rect

[eager umbra]

ye i fixed it, thx tho

[potent ice]

pygame.rect is a module as the error states

[eager umbra]

mhm, syntax is reaaaallly important in python lmao

[potent ice]

That goes for any language 😉

You get used to the naming rules. Classes usually start with a capital letter at the very least.

[eager umbra]

hey i have a problem again,

i have this piece of code

Hey @eager umbra!

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

[eager umbra]

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

and for some reason it comes out as a syntax error but idk what im doing wrong

oh wait

ther is no way that s it

OH MY GOD

thank you sooooooooooooo much

[earnest hinge]

If panda3d is derived from C++, does that make it fast enough to make large games?

[tranquil girder]

Yes

@earnest hinge It's been used for some commercial large games, so I'd say yes

[dusky jetty]

has anyone made a fps in python

[tacit lion]

Yes probably, but trust me that wouldn't be a great idea

If you mean by using python as a scripting and such backend then use most games probably do, but a game purely written in python isn't exactly a great idea

[tranquil girder]

yes, I made one for last pyweek where you shoot arrows
it's more like a prototype though, not a full game

s

[last moon]

you can use python for sure, most* libraries use either opengl or sdk hooks (tkinter might be an exception to that?)

but c#/unity and godot are pretty popular for starting out

[tacit lion]

c# + unity, blueprints + unreal

[shut sand]

no game engine???

[sleek pawn]

Is anybody experienced with the Panda3D game engine here?

[dawn quiver]

yeah i was wondering that as well, the games mentioned are terrific

[normal silo]

You don't need a game engine to make a game, or another way of thinking about it is that you make a very small engine specific to the game being made.

[chrome oyster]

yeah, sort of

you might wanna join the Panda3D discord for anything about that

[midnight girder]

@midnight girder there are a lot of ways to do so. You might want to check out https://arcade.academy and https://learn.arcade.academy

Yas

I agree

[blissful depot]

I think that it is possible but it isn't as easy as making PC games

[worldly flare]

why should someone use that?

[proper coral]

how does panda3d / ursina compare to unity/unreal engine?

[olive parcel]

The first two are open-source Python software libraries, the last two are massive commercial engines for C#, they don't compare in the slightest

[tranquil girder]

I guess ursina is slightly inspired by Unity, with the Entity/GameObject similarities, automatic update function, Mesh class and some functions like invoke(). That's about it though

nvm i fixzed it

[fiery nexus]

i dunno where to put this so ill put it here

can png's store more than just pixel data

i had a HGT height map (satellite data height map) turned into a png and my python PIL png reader is somehow reading the actual height of what each pixel is representing rather than the coulour of the pixel. (its a grey scale image for visualisation so i got no clue how this happened)

im not sure if its a bug or if this is some magic

[dawn quiver]

hey someone can tell me which programs i can use for game development?

[frosty shard]

So I'm making a 2d top-down battle game, basically you move your little knight around fighting baddies lol. What is the best way to detect if a bad guy is hit when the knight attacks?

My idea of doing this is just by creating a loop that goes through a list of all the baddies (lol) and checks if anyone of their coords are in front of the knight to get hit by the sword. But I feel like this will be slow and there is probably a better and faster way to do this... any advice?

Also, I'm doing this with pygame

[analog barn]

actually that math is pretty easy to calculate, Pygame is heavily reliant on rectangular collisions (because it's fast). You give the baddie a rectangle, and then give the sword a rectangle and check to see if they collide on each frame. There are also pixel masks, which detect collision based on overlap of individual pixels (not as slow as you'd think but still slower than rectangles)

[analog barn]

If there is a 4.th value on top of an a set of R, G, B values, it might be the 'alpha' value a.k.a the level of transparency of that pixel 0 is full transparency, 255 is opaque. Do the values go above 255?

[dawn quiver]

no. 255 is the max val. 0 - 255 is like the 0-1 scale.

[dawn quiver]

and yes 0 is transparent and 255 is opaque.

[fiery nexus]

@analog barn yea im getting numbers from 0 , 7 digits

and theres no RGB array either

PIL is reading each pixel as a int

[balmy wharf]

what would be the best way to implement a dialog-box in pygame

the way i want it to work is if you are near an interactive object and press e everything freezes the dialog-box shows up and then text is displayed everything remains paused until the user presses e again

[dawn quiver]

you just stop listening for events, and only display the dialog box on the screen.

create a boolean called dialog_open and set it to True if it is open. now , when checking for keypresses, just add an if statement checking whether dialog_open is False, or not. Freezing everything becomes quite simple then. if the player moves, by pressing keys, then if the keys wont respond, the game doesnt move on.

[balmy wharf]

@dawn quiver thank you so much, this makes so much more sense to me now 👍

I will try to have the program stop listening to events in the main loop but create a separate loop to wait for the second e press

my only concern is that pygame will process everything so quickly that the one e press will constitute the dialog box opening and then immediately closing

[dawn quiver]

not really. for instance:
for event in pygame.event.get(): if event.type == pygame.KEYDOWN: if event.key == pygame.K_e: # check dialog box open status if dialog_open == True: # skip the current dialog contents # just an example: dialog_box.clear() # write new contents: dialog_box.write("new contents) if dialog_open == False: # check for player interactions if . .. .. .. ... .. .. else: pass

that wont happen until you include pygame.keys.get_pressed(), which might cause unexpected bugs.

and if you want the dialogues to in some sort of order,
you can create a new variable that keeps on incrementing when you press e, when interacting with something.

and use that index to access contents to be displayed in a dialog box, that may be stored in an array of some sorts.

[iron trail]

im trying to load sprites into a dictionary like this

[silk tartan]

anyone knows about pygame objects' textures

[tender dagger]

what do you want to know?

[silk tartan]

how to use them

and how to then animate them and all

like if wanna have a moving ant

maybe not animate

that might be too hard

but at least a texture

@tender dagger do u know how to do it

[tender dagger]

I don't know pygame obj, but I know other texture file types
jpeg, png, targa
you can make a sprite for a 2d animated ant, but it depends on what you are doing to make the game element and how you set it up

I know more 3d than 2d

[silk tartan]

well i need specifically with pygame

i just wanna basically use an image and be able to rotate it instead of having like a square

[tender dagger]

not sure, but this data here might get you started https://ehmatthes.github.io/pcc_2e/beyond_pcc/pygame_sprite_sheets/

but for 2d anim i would recommend using sprites or a sprite sheet, not sure on pygame able to use transparency

            self.player.add_score()
            print(self.player.get_score())
            self.setup()    # focus on this
        elif self.ball.right > SCREEN_WIDTH:
            self.enemy.add_score()
            print(self.enemy.get_score())
            self.setup()    # focus on this

is there a better way of doing the self.setup() part that conforms to arcade conventions?

[last moon]

usually you'd want to only call your setup method once to set up your spritelists, base objects, etc and have everything be drawn in your draw method

[sharp cedar]

i need to reset the positions of the player, ball and enemy and some fields though

    def setup(self):
        """ Set up the game here """
        self.player.center_x = 5
        self.player.center_y = SCREEN_HEIGHT/2

        self.enemy.center_x = SCREEN_WIDTH - 5
        self.enemy.center_y = SCREEN_HEIGHT/2

        self.ball.center_x = SCREEN_WIDTH/2
        self.ball.center_y = SCREEN_HEIGHT/2

        dir = uniform(0, 1) * 360
        print(dir)

        self.ball.change_y = BALL_VELOCITY * math.sin(dir)
        self.ball.change_x = BALL_VELOCITY * math.cos(dir)

this is what setup looks like btw

[last moon]

class Player:
  def __init__(self, starting_position: Vector):
    self.starting_position = starting_position

  def reset(self):
    self.position = self.starting_position```

ei keeping the original position in the objects instance

[sharp cedar]

that does look neater

[last moon]

also it's a personal opinion but having a vector class is super useful especially for readability

even something as basic as

class Vector:
  x: float
  y: float```

so instead of having 2 different variables .._x and .._y, you can access it by it's methods pos.x, pos.y

• if you want to get real funky, you have operator overloading available if you need it

[sharp cedar]

yeah that's an excellent idea

thanks

[last moon]

np

[sharp cedar]

i need some direction in how i would go about doing this. basically, i am polishing my pong game and i want to have some sort of timer before the ball moves when a round starts. A round starts when 1) when the game starts 2) when someone scores (when ball touches left or right edge of the screen). I am using arcade btw.

@olive parcel Hey, how do I change the target frame-rate for Panda3D in python, and how can I uncap the fps (run as fast as possible) for a Task. I tried setting vsync to false, no difference.

[olive parcel]

@normal silo The setting is "sync-video false". Note that some drivers ignore it, in which case you need to look for driver settings or driver-specific environment variables like __GL_SYNC_TO_VBLANK

To limit FPS, you can set clock-mode to limited and clock-frame-rate to the desired FPS.

[normal silo]

self.vsync = ConfigVariableString("sync-video")
self.vsync.setValue("false")

Is how i'm trying to change the settings, maybe i'm doing it wrong

[olive parcel]

Well that's going to produce a warning that you're changing the type of a ConfigVariableBool

You also need to make sure it's set before you initialize ShowBase.

[normal silo]

vsync = ConfigVariableString("sync-video")

vsync.setValue("false")
app = MyApp()
app.run()

So before, but also ConfigVariableBool, not String

I actually don't get any warning from this.

[olive parcel]

The typical way to do it is loadPrcFileData("", "sync-video false")

That func is imported from panda3d.core

See above though, some drivers don't obey Panda's requests.

[normal silo]

Yeah it's probably my drivers then, there seems to be no effect.

[olive parcel]

There are other ways to override this, depending on the vendor

They're not Panda-specific.

[normal silo]

Should clock-frame-rate always work?

Well I guess only if vsync does.

[olive parcel]

It does

But it only limits, never increases.

So it can't undo the effects of vsync.

[normal silo]

Yeah

[olive parcel]

There are other clock modes that do increase frame rate, but only by lengthening the definition of "second", eg. for video recordings

[normal silo]

I guess I will have to try setting the environment variable.

[olive parcel]

Going to bed, afk

[restive lantern]

What should i learn first? Ursina or panda3d?

[rich coral]

I am hosting a Game Jam, is this a good channel for putting it in?

[covert yoke]

I would send a modmail to get permission regarding advertising, they'll also direct you to the appropriate channel if approved

[rich coral]

ok thank

hi

[dawn quiver]

first of all, it is not true it is True for python.

secondly, it is set_mode() not set_mod()

third, replace your code with mine:
import pygame pygame.init() display = pygame.display.set_mode((800, 600)) pygame.display.update() open = True while open: for event in pygame.event.get(): if event.type == pygame.QUIT: pygame.quit() pygame.display.flip()

[zinc cypress]

how to start learning pygame

[ashen condor]

i dont know if there is the right place, but i'm working on a simple ant colony simulator, i'm trying how to create a smooth random movement
does anyone have a good solution?

[iron trail]

is pygame okay with asyncio tasks?

[ashen condor]

nop, i'm using ursina engine

[iron trail]

i tried making pong online, tasks just never run

[last moon]

did you use sockets?

[iron trail]

im using websockets

[last moon]

either way you shouldn't be using async for sockets, it doesn't actually run on separate threads

[iron trail]

async def move_enemy(ws:websockets.WebSocketClientProtocol, enemy, lobby, host):
    print("moving enemy")
    package = {
        "reqtype" : "getCoords",
        "host" : host,
        "lobby" : lobby
    }
    await ws.send(json.dumps(package))
    resp = json.loads(await ws.recv())
    enemy.y = resp

async def update_coords(ws:websockets.WebSocketClientProtocol, player:Player, lobby, host):
    print("posting Coords")
    packet = {
        "reqtype" : "postCoords",

        "lobby" : lobby,
        "ypsos" : player.y
    }
    await ws.send(packet)

async def main():
    lobby, host, ws = await setup()
    player = Player(300)
    enemy = Enemy(300)
    run = True
    win = pygame.display.set_mode((WIDTH, HEIGHT))
    clock = pygame.time.Clock()

    while run:
        asyncio.create_task(move_enemy(ws, enemy, lobby, host))
        keys = pygame.key.get_pressed()
        clock.tick(30)
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False
        if keys[pygame.K_w]:
            player.moveup()
        if keys[pygame.K_s]:
            player.movedown()
        refresh(win, player, enemy)
        asyncio.create_task(update_coords(ws, player, lobby, host))

    pygame.quit()
    quit()
if __name__ == "__main__":
    asyncio.get_event_loop().run_until_complete(main())
    asyncio.get_event_loop().run_forever()

never updates player coords or enemy coords, shame

[last moon]

idk if this is the reason its not working or not but id suggest using multiprocessing or even threading

[iron trail]

so do i create threads where i update player and enemy pos every x amount of time?

[last moon]

that should be controlled by your main thread, but you need to create others for sending + receiving the data / what's been updated

[iron trail]

do i need to switch from websockets to sockets?

ive heard that async doesnt behave well with threading

[last moon]

https://stackoverflow.com/a/49899135 looks like it's possible but im not familiar with websockets sorry

[iron trail]

i think i got it

.png image not accepted in pygame sus

[fathom helm]

yeah cant do that either so I can't make my game :(

[zinc cypress]

yes;(

[iron trail]

can anybody tell me why my game is very jumpy, but only one way?

[dawn quiver]

hello

i have a problem

so if i have an arrow and its facing upwards, to move it i would decrease y

if its facing right, i would increase x

and etc

my question would be, how would i know how much x/y should i change by if the angle is unknown

for example if the object is facing upwards the angle is 0

if right then 90

and etc

but if the angle is for example 233, how would i then know by how much should i change x/y if i want to move it upwards

[normal silo]

@olive parcel In Panda3D where does taskMgr come from? I don't see it imported in the docs.

[olive parcel]

You can import it from direct.task.TaskManagerGlobal

For historical reasons it gets written to the builtins scope of the Python interpreter

See https://docs.panda3d.org/1.10/python/reference/builtins

[normal silo]

ok, what exactly is direct? Why is it called direct? Would something like this not be in core normally?

[olive parcel]

@normal silo direct is a Python library on top of the core Panda engine, which is c++. They used to be separate things when they were being developed at Disney: PANDA stood for Platform Agnostic Networked Display Architecture, and DIRECT stood for Disney's Interactive Real-time Environment Construction Tools.

[restive lantern]

You could also use vectors and rotate them

That works really well

[dawn quiver]

i already solved that

now i have a solely pygame problem

https://stackoverflow.com/questions/4183208/how-do-i-rotate-an-image-around-its-center-using-pygame/54714144#54714144

i need help on how can i recreate the last example of rotation in the first gui's response

this one

@restive lantern

[restive lantern]

Look you have to rotate the image then make a rect of the rotated image and then set the center of that rectanlge to a single point

[dawn quiver]

but idk how to do it

and all that code that guy put there is too difficult for me

[restive lantern]

You have to look into the pygame documents

There are functions for rotating and for making a rect out of an image

[dawn quiver]

no no

that guy in the stack overflow made his own functions

cuz the original pygame.tranform.rotate is complete shit if im being honest

if u look at that stack overflow post i linked that guy shows how he did it how i want

but its very difficult

so i need help figuring it out

[restive lantern]

But at the end of the day he is still using the pygame transform and get_rect

Its the exact same thing but this guy makes a function that also rotates it around a diferent point

And to be honest he did some things wrong

[dawn quiver]

can i screenshare to u

i want to show my current problem

@restive lantern

[restive lantern]

I cant right now

[digital gorge]

hey

hey anyone good programming for computer graphics?

[versed iris]

dude why you gay

[dawn quiver]

You can post your query here.

[last moon]

I think I finally know how to properly word what I was trying to ask here, altho it might be more of a system architecture question. How does the vertex buffer actually get loaded into vram from ram? (im assuming it'd get loaded into ram first?)

[normal silo]

Your gpu driver sends it.

[last moon]

can you get any more specific?

[normal silo]

The gpu driver controls the hardware which opens data lines between the RAM and the GPU.

[last moon]

what's the hardware?

[normal silo]

The computer hardware. The physical device.

[last moon]

do you know what the actual hardware is?

[normal silo]

Depends on the device

for something like a mobile phone, the cpu, gpu, etc are integrated aka SoC.

In that case it's some unknown silicon that the data travels through.

Only the manufacturer knows and a few hackers.

For something like a PC, it goes through the motherboard.

[last moon]

so it'd be just some data bus?

[normal silo]

PCI, AGP, or PCIe, etc.

[last moon]

ok thanks that actually clears up a lot for me

[normal silo]

it's a bit more advanced than a normal bus

it acts a lot like networking

(because of the large number of required features added over time, e.g. more than one gpu)

[last moon]

ill have to look into it more, it's really hard to find anything tho if you don't know what to search for

at least for this sort of stuff

[normal silo]

There is probably a discord and a subreddit for it if I had to guess.

Mmmm... ok do I need to type everything same?

no

[dawn quiver]

ok

[dawn quiver]

Yeah and this 'something' what do I need to do with it?

[pine marlin]

Set it to whatever you want it to be

[dawn quiver]

Ok.

[olive parcel]

Yes, you can't name your python file in a way that conflicts with existing module names

[crisp junco]

does anyone know a super easy way to make a infinitly generated world, one that a idiot like myself would understand, if so DM me pls

[olive parcel]

@sonic belfry yes, spawn a copy of the world in 8 times around your current world, and when the player enters one of the surrounding copies, you position them back in the same position in the original copy

[worldly flare]

wanna generate a 2d map in pygame

how to do that?

[quasi valley]

ok can someone help me with this?
split() returns a list of strings right
so x = line.split() should be able to be indexed like this: print(x[0])
so why does it give me an IndexError: list index out of range?

    def GetScores(self):
        scores = dict()
        with open(self.directory + "/highscore.txt", "r") as score_file:
            for line in score_file.readlines():
                x = line.split()
                print(x[0], x[2])

        return scores

[olive parcel]

@quasi valley presumably there is a line that does not contain at least 3 elements

There might be an empty line at the end, or something

You could skip empty lines

[quasi valley]

ah

but my file just looks like this:

Apr-02-2021-00 - 450

[grim cave]

you could add a try and except block

just in case

[quasi valley]

Yeah i tried that

I fixed it tho

[grim cave]

also it splits due to whitespaces

[grim cave]

oh cool

peace

[quasi valley]

turns out one of my files that i didnt check had a messed up line lmao

[grim cave]

F

lol

[quasi valley]

had thought i checked them all xD

yep

no wonder debugging is easy in python XD

[neon ferry]

Prob one of the best.

[grim cave]

true

[deft locust]

does anyone know why the images wont load even though I have them saved?

[pine marlin]

Are the images in a subfolder? If so use the directory of image including the sub folder

[deft locust]

wym by that. They are saved in the same folder as the game

[quasi valley]

are the images in a subdirectory like images/racecar.png

or in the same dir as your game file

@deft locust

[deft locust]

Same directory as my game file

Use 1 = instead of 2, two checks if those things are equal

Nevermind, just used another keyboard and it worked

[fallow mason]

I am currently making a game called Hog under an archive of UC Berkeley's CS61A Summer of 2020 class. Can someone explain to me why 2 0
5
4 3
13
6 9
21

is the expected outcome of this

please

[quasi valley]

I think you need to call echo like echo()

[fallow mason]

so what this is is a test in which I need to unlock in order to proceed writing code for the Hog game. What one would do is roll the dice and it will cycle through make_test_dice(2, 3). always_rolls(1) rolls the dice (cycles through it) once. So 1 dice roll goes to 2. Another goes to 3. The above file shows some rules of the game that may apply. What I'm confused about is the relationship between total() and echo(). Every odd numbered line in the list of numbers I provided are Player 1 and 2's scores. The even numbered lines are the total after each turn I think.

[thorny oak]

hi i made a class but im having trouble implementing it into my main code

[dawn quiver]

can someone explain this pls?

[tulip barn]

So i am making this rpg thing and i want to implement a fighting system. I want it to be based on the player's health, armor, strength, and his opponents health & strength. How do i do that?

Like how do i decide if the player missed his hit or no and how much health he lost and if the armor protected him

And all that math boring stuff

[proper peak]

well, if you're thinking of it as "boring math stuff", copy the mechanics of some existing rpg or something

[tulip barn]

I dont dont like it

I quite actually enjoy making it but i kinda suck at it?

[last moon]

id start with trying to figure out the base dmg, how the prot will work, crits, etc, etc

after that start working on conditional randomness

[tulip barn]

But looking at some existing stuff could help where can i find it?

[last moon]

I've got a bit, it's not great but it's the basic concept

[tulip barn]

Can i have a look?

[last moon]

ya lemme find it

[proper peak]

Wikis for RPGs usually say how the mechanics work

[tulip barn]

Aight ty

[last moon]

https://github.com/The1Divider/__insert_name__-rgp/blob/main/Game.py#L168
I really have to emphasize it's not great

[tulip barn]

Its alr i aint that professional of a programmer either lmao

Just the fact that u use the math module makes u better than me alr

😂

[last moon]

https://github.com/The1Divider/__insert_name__-rgp/blob/main/Game.py#L227 only once 😄

[tulip barn]

What are the directions for btw?

[last moon]

that one line took me + a friend like 6hrs to figure out

[tulip barn]

Is that like a 2d game on the console?

[last moon]

user would type in a direction -> player goes in that direction -> encounter logic is done ...

it was just a console game

I wouldn't even call it 2d

[tulip barn]

Like text based or 2d?

[proper peak]

noice

[tulip barn]

Ok i am confuzed alr this is complex i am trying to make something simple 😅

[last moon]

if you look past the shitty signal handling it actually is pretty simple

[tulip barn]

I just need to know how to calculate the damage

And how to determine how much health is lost

[last moon]

dmg_done = base_dmg + crit * crit_chance - block * block_chance[optional], with: crit_chance, block_chance = random(0, total_chance) is in range

[last moon]

thats what I meant with this btw

[tulip barn]

I could just do
damage = random.randint(0, strength)
But that'd be boring wouldn't it? :joy:

[last moon]

you're also leaving almost all of it to chance

rpg doesn't stand for randomly played game 😄

[tulip barn]

Do i make critical hits? Like i aint making my rpg that complex

[last moon]

the beauty of this 'general formula' is that you can leave any part of it out and it'll still work for the most part

[tulip barn]

For me it'd be human fighting monsters so that eliminates blocking right?

Cuz monster r dumb

[last moon]

but different monsters might have different weaknesses?

[tulip barn]

ok see that'd gettin complex

I want it simple

[last moon]

it just adds a layer of complexity to the game so it's not just pressing the attack button over and over

even with the one I sent, the combat is literally just pressing '1', there's no point in blocking

[tulip barn]

Its text based to their aint even buttons

And also it'll be auto fighting i just want to tell the guy if he won or no

Player*

[last moon]

ah

[tulip barn]

I am making a discord bot if u haven't relized yet 😅

dmg_done = base_dmg + crit * crit_chance - block * block_chance[optional], with: crit_chance, block_chance = random(0, total_chance) is in range

The problem with this is that all this is variables

[last moon]

(also not python btw)

[tulip barn]

Like how do i determine the base damage or critical damge or chance

[tulip barn]

Yeah this all is math related ik

[last moon]

depends on the rest of the system, I cycled through weapon(s)/armour equiped and made the stats that way https://github.com/The1Divider/__insert_name__-rgp/blob/a92875960b9a5d9e817397073a14713db7768b85/InventorySystem.py#L486

but if you wanted just base stats then you'd probably want them based on player/enemy level

[tulip barn]

Aha

Alr

Imma work my mind a bit to figure stuff out

Ty

[last moon]

also just a massive heads up, signal processing when your game is solely text based gets complex very quickly

I fully refactored this project ~3 times to try to fix it and was working on a 4th before giving up

[tulip barn]

so ur project doesn't work?

[last moon]

last time I checked no

[tulip barn]

ya done all that and gave up?

damn why

[last moon]

haha ya it just got really complex, trying to display inventories + properly type everything + dealing with i/o just got extremely convoluted

I think ill try to rewrite it but using arcade or some sort of gui over the summer

[tulip barn]

gl

would you like to see how far i am with my rpg discord bot?

[last moon]

ping me in a couple hours if you're still around im working on a school project atm

[tulip barn]

[short wing]

Yes I solved the problem. @bold tulip

Hey guys how do I make an object in pygame move around in ellipse? And I also want one more object to move in an arc shape, like the banana kick in football.

[restive lantern]

Im not really sure about the elipse but for the arc you are gonna need a parabola equation

[versed turret]

anyone got some examples for games

[rigid brook]

Hello

I was working with pygame and pyopenGL
I am making an app and i need to blit some things which is Not possible with openGL
I have tried blitting onto another surface and then converting that surface to openGL textures but that didnt work

can anyone tell me a way to set a surface for openGL, such that i can use Pygame normally like i would in non openGL projects and for openGL part, I can blit on the surface and then blit that surface on the main surface

thanks in advance :)

[dawn quiver]

some one explain me this pls

[rigid brook]

it says there is No such file

[dawn quiver]

i know but how can i fix it?

[rigid brook]

is the image (spaceship_yellow.png) in Assets folder?

i dont use VS code so am not sure

but i think it is not in Assets

[dawn quiver]

yes it is

weird isnt it?

[rigid brook]

got the error

[dawn quiver]

wait

[rigid brook]

the main.py file is not in the PygameForBeginners folder, so there is no Assets folder in its directory

[dawn quiver]

should i send you the code in private message then you try it out

i use python 3.8

[rigid brook]

its Not about the code

its directory structure

[dawn quiver]

and what is supposed to get fixed?

[rigid brook]

move the main.py file in PygameForBeginners folder

[dawn quiver]

ok

i did now but it still says

the no directory fail

[rigid brook]

then idk

😦

[dawn quiver]

because when i run the game

it opens the programm but its broken graphic

wait i am making a screenshot

[rigid brook]

ok

[dawn quiver]

it should be a 2d space game

look

[rigid brook]

the image might be curropted

or the position of blitting would be incorrect

[dawn quiver]

i was thinking about that too

[rigid brook]

is it working when opening in VScode?

[dawn quiver]

yes

is it about the ide?

[rigid brook]

wierd

no

not about the IDE

can u send the code ?

the part where you blit the image

[dawn quiver]

what do you mean

the main code?

to run the programm wait

can someone fix this?

@pale schooner can you fix this?

[tranquil girder]

You either didn't install it, or you have multiple python installations and you installed to the wrong one

[dawn quiver]

i have ursina installed

wait i chose the wrong interpreter

now it works

but its corrupted i think

@tranquil girder the game works but how do i leave it i think i forgot to add a panel

Hello, I'm making an online multiplayer Pong game using pygame and sockets. I have a client.py and server.py. The way I'm communicating between client and server is using pickles library. I'm sending and receiving player and ball objects continuously b/w client and server and server is keeping track of the positions of players and ball. I wanted to know that when I pickle an object and send it from server to client, it's actually sending a copy of the object to the client, right?

[severe saffron]

are you asking whether changing the object on the client will also change it on the server?

also be aware that this way of doing it allows the client and the server to run any code they want on each others' computers

[manic moth]

Exactly yes. i need it for only one use case. I just need to change an attribute of the object in the client, and I want that affect to take place in server as well.

[manic moth]

sorry for my poorly framed sentence. English is not my first language.

[severe saffron]

sure no problem

[manic moth]

what? how?

[severe saffron]

pickle does not automatically synchronise changes to objects over the network

[manic moth]

ok so, I'll need to send the object back to server??

[severe saffron]

yes, although there are much simpler and more efficient ways of doing this
