I'm not 100% sure but coming from c++/pyglet it's just good practice even pygame does handle it

it does handle floats

only that it passes some errors some times

last moon Oct 17, 2020, 10:31 AM

"Be aware that `range(..)` will not work reliably with float values"
"You should keep track of the "real" position of your object and only round the moment you draw you object on the screen. This prevents rounding errors to add up."```
<https://stackoverflow.com/questions/28257255/how-do-i-deal-with-pixels-in-pygame>
you don't have to but again, it's bad practice not to

merry echo Oct 17, 2020, 10:31 AM

#

That's because pygame uses SDL, which doesn't handle floating point rendering

#

Other libraries like pyglet and arcade uses OpenGL, which does handle the rasterization for you

last moon Oct 17, 2020, 10:33 AM

#

I'm not saying pygame/other libraries can't handle it, I'm just saying using // won't hurt

merry echo Oct 17, 2020, 10:36 AM

#

Yeah for pygame, do pass integers for drawing, other libs no need

#

Wait, does that mean in pygame you can't scale and scroll the viewport in floats

exotic aurora Oct 17, 2020, 10:45 AM

#

@exotic laurel u use pil and you just go thru each pixel on the image,using 1 or more loops, and just replace the pixels with the required color

merry echo Oct 17, 2020, 10:46 AM

for @exotic laurel 's ques?

last moon Oct 17, 2020, 10:48 AM

#

found what I was looking for

#

"Floating point (float, or double types in C,C++) are most often used to represent fractional units but these are not always available (no hardware support or on low end microcontrollers no library software support). If hardware support is not available then floating point can be provided via a software library, however these libraries are generally atleast an order of magnitude slower than hardware implementations. If the programmer is clever, integer math can be used instead of software floating point resulting in much faster code. In these cases fractional units can be represented with integer registers (short, int, long) if a scaling factor is used"```

The renderer should be the one handling that, not the user
if the user handles it, the renderer doesn't have to

if the user handles it, the renderer doesn't have to
GPUs are designed to handle floating point numbers, so much that it didn't even have integer support before. Not really good design to give that task to the user, but really this is an SDL problem, not so much on pygame

"It's correct that Pygame does not use the 3D acceleration capabilities of your video card. This is because it is based on SDL which has the same limitation. One alternative is to rewrite your game in a system like pyglet which does natively support OpenGL accelerated sprites, to find a similar library for graphics only, or to write the OpenGL code yourself for this."```

last moon Oct 17, 2020, 11:58 AM

also the docs actually look decent and modern

and not green 💀

merry echo Oct 17, 2020, 12:01 PM

I just realized pygame is actually open source
There's no direct link to the github source anywhere on the docs

last moon Oct 17, 2020, 12:02 PM

like it's just not good

it's not bad but it's not good

But I think pyglet and arcade need more exposure

last moon Oct 17, 2020, 12:03 PM

I actually spoke with one of the pyglet devs about the lack of use

#

I think most of the time people are turned away, it's mostly because the docs expect you to know quite a bit already

merry echo Oct 17, 2020, 12:04 PM

#

indeed

last moon Oct 17, 2020, 12:05 PM

but they said it's a hard line to tread because they don't want to explain every minute detail

idk I think a couple decent tutorials + better docs would make it better

indeed

Yes my thoughts exactly

similarly for panda3d

there are ton of things in the docs ,but no vid

absoloutely seems like a ded thing

panda3d seems existent, but still non-existent

last moon Oct 17, 2020, 12:07 PM

^ Nobody's ever mentioned it outside of listing 3d libraries

merry echo Oct 17, 2020, 12:07 PM

#

I haven't gotten into panda3d but it looks great, played a game made on it this last pyweek

exotic aurora Oct 17, 2020, 12:07 PM

#

cuz its rarely used, only because theres no decent tut

#

yeah its real cool

#

especially if u want to build fps styled games

merry echo Oct 17, 2020, 12:08 PM

this is the game, its actually amazing

exotic aurora Oct 17, 2020, 12:09 PM

actually, a new game engine was launched for python

made out of panda 3d

called ursina engine

last moon Oct 17, 2020, 12:09 PM

engine?

exotic aurora Oct 17, 2020, 12:09 PM

its so dynamic and easy, but on other hand, quite slow

yeah

engine

last moon Oct 17, 2020, 12:09 PM

ya I was gonna say

exotic aurora Oct 17, 2020, 12:09 PM

#

for making fps styled games

last moon Oct 17, 2020, 12:09 PM

#

there's no way there's a fast py 3d engine

exotic aurora Oct 17, 2020, 12:10 PM

it even has a function called FirstPersonController() which helpps u walk around 3d objs u created

#

here https://www.ursinaengine.org/

last moon Oct 17, 2020, 12:10 PM

#

ah see i've implemented that in pyglet

exotic aurora Oct 17, 2020, 12:10 PM

#

open sourced, made out of panda3d

last moon Oct 17, 2020, 12:11 PM

#

if it's pretty slow tho I can't say I'm too willing to use it

exotic aurora Oct 17, 2020, 12:12 PM

#

not that slow

#

in the example progs, ull see a minecraft clone

#

imagine

last moon Oct 17, 2020, 12:13 PM

#

that's not really a benchmark tho

#

you could probably get away with making a 'half'-decent one in pygame

exotic aurora Oct 17, 2020, 12:13 PM

#

it isnt. but the ability to have such a clean example, right there when u start, its just amazing

last moon Oct 17, 2020, 12:13 PM

#

true

exotic aurora Oct 17, 2020, 12:13 PM

#

have u ever seen such an example for opengl?

last moon Oct 17, 2020, 12:14 PM

#

I saw one for pyglet

#

so yes?

exotic aurora Oct 17, 2020, 12:14 PM

#

pyglet? yeah. but creating one, within some 10-12 lines of code? never

#

see this https://www.ursinaengine.org/documentation.html

last moon Oct 17, 2020, 12:15 PM

#

but that's built on top of a pre-existing 3d library

exotic aurora Oct 17, 2020, 12:15 PM

#

yeah

#

still

last moon Oct 17, 2020, 12:15 PM

#

so wrappers would be expected

#

well it's like pandas vs numpy

#

but less of a difference

#

tic-tac-toe in 67 lines is impressive tho

#

the lack of OOP is not

Any of you guys have networking experience with pygame ?

#

web based?

true willow Oct 17, 2020, 12:26 PM

#

But im implementing that in pygame

#

No

#

I was trying to mess around with pygame and sockets

last moon Oct 17, 2020, 12:27 PM

#

pygame's got no networking in it, you'll just be dealing with passing arguments (positions, etc, etc) - basically just variables

#

might be a better question for #networks

true willow Oct 17, 2020, 12:28 PM

#

i know but i am using sockets to send and receive these positions

#

Among clients

#

So every movement or screen update appears on both clients screens

#

It all works fine if that is being done on one laptop, but when i use two, there is a big delay on one laptop

last moon Oct 17, 2020, 12:29 PM

#

ah I remember you were asking about this before

#

It's either an issue with the speed of sending/getting the sockets, the speed of pygame updating, or both

#

how are you creating the sockets?

@exotic laurel have you set PYGAME.SRCALPHA?

when setting your rect surface you can also use rects.set_alpha(128)

rects being the surface (rect)

I could be wrong, but pos might be getting a new Rect every time you call it

screen.blit(background, pos, pos) isn't how you use blit tho

dawn quiver Oct 18, 2020, 12:46 AM

i have tried pos.x += 20 and this

so if .move() makes a new rect or something i got the same results with pos.x and y

oh wait

oops i did anoth pos

which should i learn pygame or arcade

any idea

last moon Oct 18, 2020, 8:10 AM

#

Depends what you want to do, if you want to make a 2d game I'd suggest arcade, if you want 3d, pyglet or apperantly ursina's decent

#

But you can also make games in (g)ui's like pyqt, kivy, etc (I can't think of any more decent ones but there're more)

merry echo Oct 18, 2020, 9:54 AM

add it to the x value of your rect

so x+(sw-gw//2)*blockSize ?

merry echo Oct 18, 2020, 9:56 AM

# outside the for loop
offX = (screen_width - grid_width) // 2
# . . .
x * blockSize + offX

smoky zephyr Oct 18, 2020, 9:56 AM

but ive set both as 640, so x*blockSize +(640-640)//2 wont make a difference will it ?

grid_width would be 20 * 20

screen_wdith ?

i have a general question. im somewhere between beginner and intermediate. probably closer to beginner dont need an exact answer, just a quick mention of what to look for or a general idea of how you would do it.

if i were to make a small game with turn-based-battle and i want my combat to be something like this:

character1 selects up to 3 attacks/spells and targets for each attack, and then character2 selects up to 3 attacks/spells and targets for each attack,and then character3, and then character4... and then the turn ends.

when the turn ends, all attacks are calculated.

my character's health/stats are going to be in classes and the spells/attacks are functions with 2-3 parameters/arguments based on target hp/attackpower/res/etc.

if each player took his own turn individually and only did one attack it would be easy and i would already know how to do it. but how would you do it the way i want to do it? i need some way to 'queue' the functions up, and then for them all to be announced at the end of each turn. i've tried fiddling around with lists, but every time i try to append a function to a list it gets called when it's appended lol and i'm not sure if that's the best way anyways??

#

🙏

#

and here's what an attack would look like if it helps.

def firebolt(caster, target):
    pre_damage = (caster.intelligence * 0.4) + 20
    post_damage = pre_damage - (target.fire_resistance/100 * pre_damage)
    target.Current_HP = target.Current_HP - post_damage

mint zenith Oct 19, 2020, 10:30 PM

#

Yes, a list works. To avoid the problem of calling the function, keep in mind functions are "first class citizens" in Python, meaning you can pass around the functions themselves like you could any other object. e.g. ```py
actions = []
actions.append(some_action)

later on...

for action in actions:
action() # call the stored action function

#

To deal with storing the arguments along with the function, you can create partial functions (functools.partial), which bind/store some or all arguments along with the function object.

#

Or you can store the args in a list along with the function object.

@foggy python just watched your new devlog. wow. considering you are using pygame and PAINT. PAINT?! it looks amazing

#

i've never really gone into pygame beyond the basics, but i often hear people say its slow/outdated, does it ever hinder you? or have you just gotten used to its quirks?

How can i recreate scrolling backgrounds/camera movement in pygame?

foggy python Oct 20, 2020, 1:13 PM

#

@fierce wraith Pygame’s limits only become an issue if you want to do shaders or non-pixel art stuff. It really doesn’t give me performance issues anymore (especially with Pygame 2, which is around 2x faster).

#

With the habits I have and the types of games I make, I rarely have to consider performance. I have been cutting it close with my devlog project, but that’s because of the grass, water, and cloth. Not Pygame.

#

@exotic laurel I have a video on that.

exotic laurel Oct 20, 2020, 1:15 PM

#

Oh btw, I love your videos DaFluffyPotato, they're really helpful, really thanks for making them.

#

Yeah but I didn't quite understand the whole concept unfortunately.

foggy python Oct 20, 2020, 1:17 PM

#

The concept is just that you move everything in the game instead of moving the “camera”, because there is no “camera” in Pygame.

exotic laurel Oct 20, 2020, 1:18 PM

#

Oh alright, so how do we derive how much we'll move?

#

Would it be equal to the velocity/movement of the player?

foggy python Oct 20, 2020, 1:22 PM

#

Move everything on the screen?

#

It’s not directly related to the player position unless you want a locked camera

exotic laurel Oct 20, 2020, 1:23 PM

#

Yeah, that's what I'm trying to get

foggy python Oct 20, 2020, 1:23 PM

#

The amount you move everything is the position of the “camera”

exotic laurel Oct 20, 2020, 1:23 PM

#

Including the player?

foggy python Oct 20, 2020, 1:23 PM

#

Yes. I normally apply it to everything in the game.

#

Aside from UI

exotic laurel Oct 20, 2020, 1:24 PM

#

Ahh I see

#

That makes it a lot more clearer

I'm trying to calculate the angle of displacement with this:

class Displacement:
    def __init__(self):
        self.north = 0
        self.west = 0
        self.south = 0
        self.east = 0

    def __call__(self, direction):
        exec(f"self.%s += 1" % direction)
        vertical = self.north - self.south
        horizontal = self.west - self.east
        if horizontal == 0:
            print(vertical)
        elif vertical == 0:
            print(horizontal)
        else:
            print((math.atan(vertical / horizontal))```
but it's only giving me values between ±0-90 degrees (±pi/2 rad) whereas I want the answer within 0-360 (0-2pi), any way to do this with `math` or am I going to have to add more logic to it

sly grove Oct 20, 2020, 5:46 PM

#

(small things: seems weird to bring out a class for what could be a function; __call__ method can feel nice but makes search harder; exec is a bazooka where here you can use getattr and setattr)

last moon Oct 20, 2020, 5:50 PM

#

exec is a lot easier to use in this case, and I don't need to search, I just need it to return an angle

merry echo Oct 20, 2020, 5:50 PM

#

atan returns -pi to pi so can you just add pi to it so it goes 0 to 2pi?

last moon Oct 20, 2020, 5:50 PM

#

I can't use a function unless I return every value each time it's run

sly grove Oct 20, 2020, 5:50 PM

#

(I meant searching in the codebase, later when you want to find what displacement1("north") does)

merry echo Oct 20, 2020, 5:51 PM

#

Also what is this for

sly grove Oct 20, 2020, 5:51 PM

#

(you could use a function that returns a function)

last moon Oct 20, 2020, 5:51 PM

#

(but it's user input so idk why i'd have to do that)

#

displacement

#

so if the character walks north-north-east

#

I want the overall angle of displacement

#

so I can choose which landscape to print

merry echo Oct 20, 2020, 5:52 PM

#

Wdym by angle of displacement

last moon Oct 20, 2020, 5:52 PM

#

give me a sec ill draw it

merry echo Oct 20, 2020, 5:55 PM

#

By landscape do you mean tiles?

last moon Oct 20, 2020, 5:55 PM

#

nope

#

📎 unknown.png

#

so in this case the moves would be north-east-north

#

x displacement = 1
y displacement = 2
angle = arctan(y/x)```

Whats your use case here

last moon Oct 20, 2020, 5:59 PM

#

im separating the 360 degrees into quadrants (45-135 = North, 135-180 = West, etc, etc) and choosing a display to print depending on the quadrant + a bit of rng

#

if angle > 45 and angle < 135:
  print(mountain)```

#

that sort of thing

merry echo Oct 20, 2020, 6:00 PM

#

If you just want the quadrants, wouldn’t the sign of the diff in movement be enough to find it

last moon Oct 20, 2020, 6:01 PM

#

no I specifically need the angle

sly grove Oct 20, 2020, 6:01 PM

#

could you add the vectors then convert to angle? (I don’t know much about trig!)

merry echo Oct 20, 2020, 6:02 PM

#

So what else do you need

last moon Oct 20, 2020, 6:02 PM

#

that's what im doing in my class

#

literally just an angle that represents the full unit circle

#

like I could do if vertical > 0 and horizontal > 0 and angle < 45 but that's a lot of cases and it's not what I want

merry echo Oct 20, 2020, 6:10 PM

#

This is to find the quadrant?

#

so I compare the coordinates of the two entities then use atan2

see that almost works

#

south-east is giving me 125

#

📎 unknown.png

#

ya no I don't think that's gonna work

merry echo Oct 20, 2020, 7:29 PM

#

add 180 to your angle

last moon Oct 20, 2020, 7:29 PM

#

that should be in order tho

#

180 + 135 isn't 225 unfortunately

merry echo Oct 20, 2020, 7:36 PM

#

how are you getting these numbers

proper peak Oct 20, 2020, 8:12 PM

#

@last moon Why not use math.atan2 which is made for this specifically?

#

It gives angles from -pi to pi.

#

(normally you can replicate the same functionality by using the arctangent and also some details about the signs of x and y)

#

I would use the matrix of the agent vs the position of the player

#

local = matrix.inverted() @ position

#

then the cord is in local space

#

you can use this to know if the target is in a cone or behind you etc

#

if local.x<0:
    #target behind you
elif abs(local.y) - local.x <0:
    #target is inside 2d vision cone

#

you can use this to decide which way to turn also

#

if local.y<-.05:
    #target is to left 
elif local.y>.05:
    #target is to right
else:
     target is ~180 degree behind

#

left/right flips for forward vs back

there is no problem with the player icon, you issue with icon of the window up in icon = pygame.image.load("space-invaders.png")

Do you have image space-invaders in your folder?

#

@reef gazelle You missed the most salient part of the error message. However it looks like PyGame doesn't have macOS wheels for Python 3.8 but does have for Python 3.7, so maybe using Python 3.7 might prove slightly more fruitful

#

Or install a dev version, pip install pygame>=2.0.0.dev18

#

Or pip install --pre pygame might work too

For a project, what things should I plan before starting to code?

I would appreciate some feedback here

and I would like any answers to be in my dms

last moon Oct 22, 2020, 7:44 PM

#

@sinful frost it depends on your knowledge/the project/how you function, but if I'm working on smthing more complicated, I usually like to write down what I need to do + pseudo code is always a decent way to wrap your head around the required logic. Imo it's important to distinguish between what you need and what you want for your project - as in not overcomplicating it until you have at least a framework down (as an example (and) to keep this on topic, I'm working on a console rpg and I want to eventually add more landscapes and enemies but I won't be doing it until I have a functioning game)

#

github projects are a great way to plan it out

unkempt wren Oct 23, 2020, 2:12 AM

you said the command you did was pip 3 install pygame?

it should be pip3, without a space

yes sorry it was that

unkempt wren Oct 23, 2020, 2:13 AM

though it's not guaranteed that pip3 will install to the version of python that you're using depending on how your computer is set up, but we can deal with that

ok so basically i have a variable defined by an input, for this example lets say that input is dex, and i have a list of variables of the same name as the input, i want to call a function, using the values in the list, but when i do dex[0] it prints "d", is there a way to do this?

#

heres a shortened version of the issue that you can try for yourself:
dex = [False, "Dexterity", 3]
v0 = input("To see the problem, input 'dex': ")
def dexfunction(vone, vtwo, vthree)
print(vone + "," + vtwo, + "," + vthree)

dexfunction(v0[0], v0[1], v0[2])

stark anvil Oct 24, 2020, 12:04 AM

#

@solar rose what you're thinking

#

is that you can access a variable through a string representation of its name.

#

don't do that.

#

use a dict instead.

solar rose Oct 24, 2020, 12:04 AM

#

i had that idea as well but im not sure how specifically i would use the dictionary in this instance

stark anvil Oct 24, 2020, 12:04 AM

#

also, you can format code blocks with ```

#

okay, I'll give you an example real quick

solar rose Oct 24, 2020, 12:05 AM

#

mydict = {dex: False, "Dexterity", 3}

#

like that?

stark anvil Oct 24, 2020, 12:06 AM

#

something like that.

#

but with a wrapping list

#

>>> fruits = {
...     'apple': ['red', 10],
...     'banana': ['yellow', 16]
... }
>>> def f(fruit):
...     fruit_data = fruits[fruit]
...     print(fruit_data[0], fruit_data[1])
... 
>>> f(input())
apple
red 10

solar rose Oct 24, 2020, 12:06 AM

#

mydict = {dex: [False, "Dexterity", 3}

stark anvil Oct 24, 2020, 12:07 AM

#

you're missing a ]

solar rose Oct 24, 2020, 12:07 AM

#

but besides that thats what you mean?

stark anvil Oct 24, 2020, 12:07 AM

#

well

#

you're also missing ' around dex

what is good pygame for? Open cv has better input 😛

fervent rose Oct 24, 2020, 9:17 AM

#

I don't like PyGame, so IMO it is just good for the garbage bin

elfin frost Oct 24, 2020, 9:21 AM

#

for simulations I don't see any advantages using any library other then opencv

I haven't tried it yet, but from the looks of it arcade is a better alternative

fervent rose Oct 24, 2020, 9:32 AM

#

Yeah, Arcade is way better IMO

merry echo Oct 24, 2020, 9:46 AM

There's still some things that Arcade is slow with, but overall its much better

I don't think pygame is bad, but it's obvious it's too complicated for newbies to get started with

last moon Oct 24, 2020, 9:51 AM

but like even the docs aren't great
like why are there comments?

@tranquil girder

the lack of complexity is sadly an issue. The PyGame devs decided to go for the easiest way everytime, which lead to a pretty bad API, with a total lack of OOP.

PyGame wants to be an introduction to programming and game dev, although it forces you to do some pretty bad practice because of their "simple" API, and for the game dev part, the lack of OOP is just a no-brainer, there's no way that one would ever do game dev without OOP.

Last but not least, still because of their "simple" API, if you strat making a somewhat advanced game, it will just turn into a nightmare, because you'll have to provide all those boilerplate code and more complex features that PyGame does not provide. I wouldn't be surprised if a production ready game made in PyGame made their own OOP wrapper around it.

Finally, outside of the library itself, their online docs are also pretty bad, they are very hard to navigate and to read, and they aren't many example available on it, let alone the fact that you can stare at them more than a minute, or your eyes will be burned by the green background.

what in the world is this compression

#

Anyways, pygame indeed makes you do some wacky practices without OOP, which wouldn't be a good starting point esp. for beginners. Not to mention the lack of modern graphics support which is quite a limitation when you want to do more than just drawing on the screen.

@little eagle arcade

fierce wraith Oct 24, 2020, 12:06 PM

#

arcade is awesome

#

especially if you want to do something like a platformer or roguelike

little eagle Oct 24, 2020, 1:28 PM

#

but there is not enough rescources for a complete beginner like me who knows only the spelling of arcade but know the python basics on online

#

Guess this is the platform

tranquil girder Oct 24, 2020, 1:30 PM

#

No, there's an incredible amount of information available online. You can learn anything you want, just google it

last moon Oct 24, 2020, 1:40 PM

arcade has a whole swack of examples of different complexities

#

https://arcade.academy/examples/index.html

#

they encourage OOP usage
which is useful across quite a bit

little eagle Oct 24, 2020, 2:01 PM

ok

I really only know the speeling of arcade so i am sorry

@little eagle idrk what you mean by that, but eventually you'll have to learn more than one library

little eagle Oct 24, 2020, 2:22 PM

#

why 'ugh'

#

@little eagle idrk what you mean by that, but eventually you'll have to learn more than one library
@last moon It means i know that there is a thing called arcade

#

@little eagle idrk what you mean by that, but eventually you'll have to learn more than one library
@last moon yes i have to learn

last moon Oct 24, 2020, 2:24 PM

from what I can see too, arcade's methods are more universally game-dev oriented

little eagle Oct 24, 2020, 2:24 PM

#

ok

last moon Oct 24, 2020, 2:24 PM

so you'll have less of an issue transitioning to another language

little eagle Oct 24, 2020, 2:25 PM

i have never tried to learn becoz it contains a lot of classes and making me forget what are classes

#

i saw in the link someone sent

last moon Oct 24, 2020, 2:25 PM

#

I mean I avoided classes/OOP for a while and I really wish I hadn't

#

there're super useful + quite a few libraries use them so knowing how they work is a plus

How would one fill a polygon given with a pointlist in pygame?

@hazy cliff there is a method for that in gfxdraw iirc

Guys m new to pygames

It will be hard time hope i will find some support here

pygame is surprisingly easy, and very comfortable to program with.

#

once you get the base down, and how things work

#

it will be a very smooth ride

@vernal kettle I'd suggest reason the above conversation before you commit to pygame

im having a problem with pygame in python3
i have this function running inside my main while loop and inside it i have this:

global keys
keys = pygame.key.get_pressed()

for event in pygame.event.get():
  ...

and for some reason the for loop (for event in pygame.event.get():) wont run even when i do something that most definitely should make it run (and i know that the function is running because i tried putting a print inside it to print some stuff and it did print so thats not why) so i have no idea why its not working (and yes i did initialize pygame)
ping me if you want to help

hey so you guys are going to say im stupid but im trying to learn python and pygame as i go and watch youtube, and i want to know if i could get some help on somethings

@inland arrow im trying to do simple things in pygame like coloring the display and all of the tutorials and stuff i find are out of date

can i see your code?

import pygame

pygame.init()

pygame.display.set_mode((500, 500))
pygame.display.set_caption("game")

gameExit = False

while not gameExit:
for event in pygame.event.get():
if event.type == pygame.QUIT:
gameExit = True
exit(1)

pygame.display.update()

i deleted the lines i had about coloring because they were bad

except you also did import pygame.display which is useless bc you already imported the entire pygame library on the first line but whatever

#

i deleted the lines i had about coloring because they were bad
@sly agate i wont judge, i mean cant help you if youre not willing to show

#

but you want to know how to color the display right?
