Every time you press the pause key

[buoyant sequoia]

ok thank you will do that

[limber veldt]

Fonts are all drawn, yay, that's a grind

Images for all the letters and numbers

I need to come up with a human controller. Liek I don't want all of a level's humans to be capturable from the start or the first wave of landers would just come snag them all at almost the same time and, no matter how good the player is, some of them would mutate by reaching the top of the screen

So, no matter how many humans remain alive, I only want one or two of them to be capturable at a time

Add all humans that are walking (on the ground, not captured, falling or being saved by the player) to a list, choose a couple randoms and enable their capturable flag

[dawn quiver]

how do you start game dev

in py

what game engine

i need

[dawn quiver]

well you can make 2d games

i recommend pygame ebcause thats what i use

[limber veldt]

You start with a game or an idea for a game and start learning whatever it takes to make that game

[frozen knoll]

You could also look at Arcade.

See https://arcade.academy and https://learn.arcade.academy

[limber veldt]

I think I'm gonna take arcade for a spin and see if I get scroll a shooter with it

Its hardware acceleration might be worth a try

[dawn quiver]

only 2d?

u cant make 3d games?

with python?

[limber veldt]

Let's put it this way, you can make game logic and all that for any game with python but when it comes to drawing things fast enough for 3d, just not fast enough

[dawn quiver]

so u cant right

bruh

[limber veldt]

Hmm, that's still conditional. Blender does 3d with a python API, but that's not python doing the drawing, it's Blender with its C or C++ code

[dawn quiver]

why r u taking so long time to answer

[limber veldt]

Because this inst't he only thing I'm doing

Aout to step out

about

[dawn quiver]

i mean

you can just say no

or yes

[pine marlin]

because its not a yes or no thing, you can make 3d games with python but dont expect some AAA level quality

[limber veldt]

Yeah, wtf, it's not like you deserve a definite answer, there isn't one

[tranquil girder]

yes, you can

[south slate]

So I wrote question on here yesterday and did not receive a response. Completely understandable since I am unable to offer anything in return for the help I am asking for. Can anyone possibly tell me where I might be able to post a question that will be possibly answered?

[limber veldt]

True determines if the set of points are closed, I assume by making a line or not from the end back to the start point of the provided list of points

And yes, that's the case...

closed (bool) -- if True an additional line segment is drawn between the first and last points in the points sequence

Pygame docs answered that question in seconds, just sayin'

Or, of course, you could try the code, and set it to False then compare the difference, surely then it would be obvious what it does

Don't be afraid to poke around with the code you're working with, it can always be fixed if you mess it up or even done better...maybe

[south slate]

Thanks for your assistance. I looked at pygame docs but didn't see anything relevant. It is possible I just did not adequately understand what is written there. I tried removing the bool altogether but did think of changing it False. I really appreciate your help.

[limber veldt]

Like I've been working on this game for over a month, it's working great but I wasn't totally satisfied with player movement....I just totally deleted the entire player movement method and started over

And it's ok, because I will write it better this time

[south slate]

Gotcha, I will try to be more willing to take risks and change up the code

[limber veldt]

Of course, I saved a backup of the working code but still, it's a good idea, at least for me, to refactor and redo sometimes

It's like as a piece of code I'm working with evolves, I gain a better understanding of the essential logics and can almost always write it better

Especially when writing long algorithms. I code out step by step then realize about 900 lines later that I'm only changing a couple of variables and can then understand how to set up a function or method to do it in 10 lines

lol

[dawn quiver]

Im having an issue where the player sprite collides with the platform sprite but it stops in the middle of the platform, im trying to make it so it stops on top of it

[south slate]

sst, lol

Thanks again, sst! I'm able to see the difference when I set the bool to False.

[dawn quiver]

https://hastebin.com/usigenibih.rb thats my code btw

[limber veldt]

Have fun man

[limber veldt]

What are the dimensions of your two images, the player and the block?

[dawn quiver]

the player is 40x64

the block is 48x49

[limber veldt]

Hmm, that's a tough one @dawn quiver

But I was watching a long tut this morning...

This is it. Sorry I can't help you more directly at the moment but I know that this covers what you need: https://www.youtube.com/watch?v=DHgj5jhMJKg

[dawn quiver]

okay thank you

[limber veldt]

And is really well done

He builds the code as he needs it and describes why he's doing what he's doing really well

Beginner friendly but for someone just looking for why their collision is messed up, it's kinda long

[limber veldt]

Excuse me but....I fuckin did it! Recreated the player/map movement!

The switching direction thing is tricky

Because the player and map both have to move in relation to each other as the player sweeps across the map during the direction change

But I'm pretty sure I got the original algorithm, if not, really really close to it

And oh man does it feel good, feels right

I've only been trying to hammer this out for two or three days

Among other things, this has been lurking and being tweaked

[limber veldt]

The key was adding a flag to signal when the player is transitioning from left to right side of the screen and adjusting player speed (actually map speed) according to it

Or right to left, for that matter

Adjusting map speed relative though, not absolute

So good, so glad I got that working right

I mentioned earlier tha tI deleted it, well some made it back into the refactor but it has all new movement code

During player update(), it also has to update the siren surface on the player sprite so it changes colors and looks kinda like a siren

Also, if the player has human cargo, check if he's at the ground and drop them off

[low lagoon]

Here's how i'm handeling collisions.

basically, you have the bounding box of the player, and then you loop over the inside of the box and use a texture to define to collisions, and then create a bounding box for the collision parts inside the player. then get the closest points with the player and the collision, then get a vector between those two points and move the player with that vector

here's the result

Not the best, right?

here's the code for getting the closest point

    closestP = [0,0]
    insideX = Center[0]-Bounds[0] < P[0] and P[0] < Center[0]+Bounds[0]
    insideY = Center[1]-Bounds[1] < P[1] and P[1] < Center[1]+Bounds[1]
    pointInsideRectangle = insideX and insideY
    if not pointInsideRectangle:
        closestP[0] = max(Center[0]-Bounds[0], min(P[0], Center[0] + Bounds[0]))
        closestP[1] = max(Center[1]-Bounds[1], min(P[1], Center[1] + Bounds[1]))
    else:
        distanceToPositiveBounds = [Center[0]+Bounds[0] - P[0], Center[1]+Bounds[1] - P[1]]
        distanceToNegativeBounds = [-(Center[0]-Bounds[0] - P[0]), -(Center[1]-Bounds[1] - P[1])]
        smallestX = min(distanceToPositiveBounds[0], distanceToNegativeBounds[0])
        smallestY = min(distanceToPositiveBounds[1], distanceToNegativeBounds[1])
        smallestDistance = min(smallestX, smallestY)

        if smallestDistance == distanceToPositiveBounds[0]:
            closestP = [Center[0]+Bounds[0], P[1]]
        elif smallestDistance == distanceToNegativeBounds[0]:
            closestP = [Center[0]-Bounds[0], P[1]]
        elif smallestDistance == distanceToPositiveBounds[1]:
            closestP = [P[0], Center[1]+Bounds[1]]
        else:
            closestP = [P[0], Center[1]-Bounds[1]]
    return closestP```

then the collision check

    global groundPos
    sizeX = abs(x2-x1)
    sizeY = abs(y2-y1)
    inputMiddleX = x1+sizeX/2
    inputMiddleY = y1+sizeY/2
    lowestX = 50000
    heighestX = 0
    lowestY = 50000
    heighestY = 0
    closestPoint = [0,0]
    closestPoint2 = [0,0]
    unintersectVector = [0,0]
    ColSize = [0,0]
    ColMiddle = [0,0]
    colDetectected = False
    stepsize = 5
    for i in range(int(x1), int(x2), stepsize):
        for j in range(int(y1), int(y2), stepsize):
            x = i
            y = j
            value = collisionMask[y][x][0]/255
            if int(value) < 0.5:
                if x > heighestX:
                    heighestX = x
                if x < lowestX:
                    lowestX = x
                if y > heighestY:
                    heighestY = y
                if y < lowestY:
                    lowestY = y
                groundPos.append([i,j])
                colDetectected = True
    if colDetectected:
        ColSize = [math.sqrt((heighestX - lowestX) * (heighestX - lowestX)), math.sqrt((heighestY - lowestY) * (heighestY - lowestY))]
        ColMiddle = [lowestX + ColSize[0]/2, lowestY + ColSize[1]/2]
        closestPoint = findClosestPoint([inputMiddleX, inputMiddleY], ColMiddle, [ColSize[0] / 2, ColSize[1] / 2])
        closestPoint2 = findClosestPoint(closestPoint, [inputMiddleX, inputMiddleY],
                                         [playerSize / 2, playerSize / 2])
        unintersectVector = [closestPoint2[0] - closestPoint[0], closestPoint2[1] - closestPoint[1]]
    return colDetectected, unintersectVector, closestPoint```

I've also got some other stuff for sliding and bouncing

            Jumps = 2
        GroundNormal = [PlayerCenter[0]-PhysicsCheck[2][0], PlayerCenter[1]-PhysicsCheck[2][1]]
        GroundNormal[0] = (numpy.array(GroundNormal)/numpy.linalg.norm(numpy.array(GroundNormal)))[0]
        GroundNormal[1] = (numpy.array(GroundNormal)/numpy.linalg.norm(numpy.array(GroundNormal)))[1]
        b = numpy.empty_like(GroundNormal)
        b[0] = -GroundNormal[1]
        b[1] = GroundNormal[0]
        SlideVec = [numpy.dot(playerVel, b) * b[0], numpy.dot(playerVel, b) * b[1]]
        factor = -2 * numpy.dot(GroundNormal, playerVel)
        BounceVec = [factor * GroundNormal[0] + playerVel[0], factor * GroundNormal[1] + GroundNormal[1]]
        Bounciness = 0.05
        playerVel = [BounceVec[0]*Bounciness + SlideVec[0]*(1-Bounciness), BounceVec[1]*Bounciness + SlideVec[1]*(1-Bounciness)]
    playerVel[0] += inputAxis[0]
    playerVel[0] = max(-PlayerSpeed, min(playerVel[0], PlayerSpeed))
    if playerVel[0] != 0 and inputAxis[0] > 0:
        if playerVel[0] > 0:
            playerVel[0] -= playerVel[0]/5
        else:
            playerVel[0] += playerVel[0] / 5 ```

[dawn quiver]

You can. But you need to use something else to draw the 3d mesh.

PUBG using python

but they use C++ to draw the characters

its basically like front end and backend

Like always another language is used for the frontend of the game, and python is used for the backend

[rotund niche]

Wow

[dawn quiver]

For the logic(if player collides with this what happens)

[dawn quiver]

Just incase you didnt know what logic means :)

[autumn pilot]

I'm automating EverQuest with Python(which isn't against TOS surprisingly). I'm wondering how to handle movement and navigation. I'm able to receive my coordinates and direction I'm facing in a particular zone using a command. But I'm wondering how to go about actually moving from one set or coordinates to another? How should I navigate around objects and such? Here's an example of a zone/map http://www.zlizeq.com/ZlizEQ_Projects-ZlizEQMap

[analog latch]

So I just installed pygame on Visual Studio Code with pip3 install pygame and when I went to run my source code, this came up:

Traceback (most recent call last):
  File "pygame.py", line 1, in <module>
    import pygame
  File "/Users/me/Desktop/Python/pygame.py", line 3, in <module>
    pygame.init()
AttributeError: 'module' object has no attribute 'init'```

What does it mean and how can I fix it?

[last moon]

because the file you're working in is called pygame.py, it's trying to import itself

try renaming it

[analog latch]

I got the same error

[idle seal]

anyone can give me some game idea?

plss

☺️

[teal ember]

some board game/ card game

any specifications

[idle seal]

thx :D

I run out of idea :)

[teal ember]

you can also think of multiplayer games

or 2 player games, p2p

like online pong, air hockey, pinball

[dawn quiver]

hmm

normally i brainstorm with what i can 75% do

so that i can learn the other 25% :D

i list out 10 games

and decide which ones seems the most fun >///<

this time i decided on a full fledged zombie shooter platfromer type game

[velvet plank]

nice

[limber veldt]

My best player class for a space alien side scrolling shooter ever: https://pasteall.org/wg6k

My margins are hardcoded at the moment, but that's just a matter of defining additional constants and using them instead, basically the same thing

So, self.x carries the float of player location x, and self.rect.x is an int. What's cool about that is that I can move player around the screen by its rect without changing its actual x location. Meaning that I can add movement effects without influencing the underlying floats

Want player ship to vibrate as it picked up speed? No problem, shake rattle and roll its rect anywhere you want, the floats and the math with them will remain consistent

So I still have to work out that additional thrust code and implement some very subtle high speed shaking

As thrust is applied to the player ship, the ship slowly moves forward on the screen while the world whips by at top speed

To further enhance the feeling of movement and speed

Still have to work that out too

[limber veldt]

Just realized that I could make kill_all() and shoot() staticmethods, neither of them reference self at all

[wicked lintel]

about the page being 'bugged'

[low lagoon]

update, i got it kinda working, but now it's sticky

    if not DesireCheck[0]:

How to make a jumping mechanism in pygame?

[frozen knoll]

http://programarcadegames.com/python_examples/f.php?file=platform_jumper.py

[wild lagoon]

can someone please help

my scrolling background

is going backwards

[limber veldt]

The game keeping 50 baiters spawned at all times, they eventually fall into this kind of pattern. Kinda how they should

So long as I don't move, they shouldn't change their flight pattern

My velocity on both axes is added to theirs. If I have no velocity, they fly a pattrn like those

That's why they can never be outran

They pull in front of you and go into the pattern at whatever speed you're going and if your speed changes, they react to it three times per second

So they have a reaction time

Which can make them hard as fuck to shoot sometimes

Because if they're just above your line of fire and you go up to make the shot, they might react to it fast enough for you to miss and draw you into a chase

Up the screen

Those enemy AIs are a pain in the backside to work out but when they work is totally worth it. I could tweak those guys some but they good for now anyway

[limber veldt]

Not a very talkative bunch in here, that's for sure. This is a chat, right?

[grim abyss]

What's happening bud!

[limber veldt]

Not a lot, chillin, coding this game

Adding player lives, he can now explode

And die

And respawn

Next, adding a game over screen for when player is out of lives

Messing with sounds at the moment though

Can I not access a subfolder of my main without using os when loading the sound files?

[next estuary]

Complex biome generation using OpenSimplex for a game

Biomes in-game

[random arch]

For older versions of libraries, namely pygame 1.9.6, how does one tend to find documentation for it, given the website documentation is updated to the newest version?

[dawn quiver]

damn thats good, if you make a huge map and pick a better more lofi relaxing colour pallet, purple and pink, or look at a game like 'Alto' this would be a great game!

[dawn quiver]

Well you spitting paragraphs of the logic behind your games is kinda hard to respond to 🙄

[limber veldt]

I don't know why, it's a game channel, people talk about games here, not just post promos or answer questions

I mean, seems like other game makers would be interested in how one person is doing it. I know I'm interested in how other people might do some of the things I talk about

But nobody talks

No biggie

Single player coding is just as fun

[dawn quiver]

Its a game channel where we discuss our games yes

not write paragraphs about the details of its logic

unless someone was making the exact same game, no one would be interested nor would they know how to respond 😄

[dawn quiver]

This is how the description should be

A nice photo/video and then what they are working on

[low lagoon]

:)

[dawn quiver]

Not the entire logic behind the code

[low lagoon]

eh, i disagree with that

[dawn quiver]

So ofc i would respond if you just said "Yep the swarmers are going at him now"

but when you try to explain the velocity and particle collision behind it, i woudnt know how to respond unless i read the entire parah or the ones before 🙄

what your doing is making a documentation of your updates

github is there for that

Here is more about where we discuss our game dev, not explain the entire thing unless anyone asked 😔

[low lagoon]

I'd say it's good to just explain the concepts behind your code in case someone knows a more efficiant way

[dawn quiver]

well you do you, but dont expect but of a response

[low lagoon]

that is comepletely fair

[dawn quiver]

Anyways

eh i have exams so i cant continue the dev on my game

after the exams i will tho

:D

[dawn quiver]

are those mushrooms??

[next estuary]

some of them yes

[limber veldt]

I like bouncing ideas around, follow me or not, I'll probably still do it

So meh

Sometimes it even helps me

[grim abyss]

i hope so

throwing ideas around is great

[limber veldt]

Sometimes I hope someone says, "no man, there's a much better way" and teaches me something

[grim abyss]

exactly

[limber veldt]

Like actual game devs in here spewing ideas would be awesome, but no, just me and I barely know wtf I'm doing

Well, sometimes others

How to set up game logic to handle level progression is the next difficult hurdle for this project

[grim abyss]

character level progression or stage progression ?

i wanna hook up with a decent artist and start doing a metroidvania

using the arcade game engine library...

[limber veldt]

Stage progression

When to spawn what and end level conditions

Like spawn three waves of five landers in each one. When those are all dead, the level ends and add bonus points for number of humans remaining alive

On the next level, spawn four waves and add one more of the harder enemies, and so on, slightly increasing game difficulty for each level

[grim abyss]

that sounds relatively easy

but I can see how it would be difficult to add it in if your design was structured to not anticipate supporting it. then it would be not fun....

[glossy quarry]

so I'm making pong rn but how do I add sound effects to my game???
I'm using pycharm as my IDE and I'm using turtle btw

[limber veldt]

Pong can be quite challenging

If you want to do more than move a ball slowly around the screen

Fast moving things can ghost right through walls

And player paddles

[dawn quiver]

os.system("afplay jumping.wav&")

use os

https://paste.pythondiscord.com/icanezaxab.apache

this is the pong game i made with turtle ^^

[limber veldt]

I once set up an a priori collision model with pong, it could handle massive magnitude vectors, way wider than the player paddles

[bitter blaze]

for event in pygame.event.get():
        if event.type == pygame.MOUSEBUTTONUP and event.button == 1: 
            (x ,y) = pygame.mouse.get_pos()
            
            if (870-x)**2 + (650-y)**2 < 325**2:
                puppychow += click
                
                count1 += 1
                if count1 < 3:
                    text(50, "+1", white, x, y)
                    
                if count1 > 3:
                    count1 = 0
``` why no work

[glossy quarry]

apparently it won't work, that was for MAC only, but no worries I found out that I need to use winsound for windows so it's solved

[limber veldt]

It calculated where the ball would hit before it got there and if the player paddles wasn't there at the calculated time, player lose

[bitter blaze]

[dawn quiver]

oh yeah

sucks that there are different types of osses

would be nice if there was a universal one yk

[agile ore]

Omg it's beautiful

[tawny crystal]

How to keep up motivation for game dev? :(

[dawn quiver]

what lib are u using btw

[dawn quiver]

:(

i honestly dont know

if i dont like making games

i would just stop

[tawny crystal]

good one

[dawn quiver]

and practise my DSA cause my end goal is ML

[glossy quarry]

just don't

making simple games is good enough

[dawn quiver]

i was really just using Game Dev as a mode of translation or dev tool

[glossy quarry]

making complex games

E

that's what I'm planning to do

[tawny crystal]

rn I'm trying to hone my pixel art skills

[glossy quarry]

alright good luck

[tawny crystal]

but I can't stop opening stepmania

and thanks

[dawn quiver]

Sorry, those are my own terms
Mode of translation: A library/programming language which you can use to learn new ones since you are very fluent in many concepts and in the functions/syntax of that library/programming language

Developer tool: A powerful "tool" that you have created by becoming very good at a specific topic/field, For example game dev, discord bot or mobile apps

You could use a dev tool to potray your ML into something presentable

[next estuary]

For what specifically?

[dawn quiver]

for example with game dev you could potray your ML as a game ai

for a discord bot it could be a chat bot

ect.

[dawn quiver]

the rendering

[next estuary]

Ursina is the game engine

[dawn quiver]

Oh.

Sad

[next estuary]

All the biome stuff is done with OpenSimplex

Why sad?

It's wicked fast considering it's python

[dawn quiver]

Because ursina does most of the work for you :)

[next estuary]

Lol

[tawny crystal]

no shot

[dawn quiver]

exactly man

im so happy

there are actual game devs here

who understand that "oH Lol You cANt ever mAke aNy fORm of Game with pyTHon that iS pLaYABle, I hAVENT triEd gamE dEv But i juST KnoW BEcause ThatS WHat EVERYONE says" is false

and it really spreads false info

[next estuary]

@dawn quiver bs there was so much work that went into dynamic chunk loading, biome generation, particle tracking, etc. Making meshes with pure math isn't easy.

[tawny crystal]

lmao true

[dawn quiver]

that you cant make games at all with python

yk PUBG using python for its logic?

C++ for its rendering

also python for its cyber security cause so many fucking hackers

[next estuary]

Python great for websites

Twitter and insta use it on their backends

[dawn quiver]

Sure, but no. I would have consdiered it cool if you had done it without a 3D 'engine' and instead used something like opengl

[tawny crystal]

this looks promising, good luck :>

[dawn quiver]

and done all the 3d perspective yourself

[next estuary]

It's doable, I started with opengl sec

This whole project started out with me wanting to render snow actually

[dawn quiver]

now thats

cool

cool af

keep it up!

[next estuary]

ursina was just far easier since you could build a point mesh then render each point as a billboard particle

Thanks I will 🙂

I'm working on seemless portals between the procgen worlds next

[dawn quiver]

why does the snow stop falling when you start changing angle tho

;(

[next estuary]

it doesn't the rotation is just way faster than the snow falling

so it's kinda hard to track the falling

also the fps drops

[dawn quiver]

:0

[dawn quiver]

oof

[next estuary]

so the downward momentum is reduced

I didn't make it dt based just frame based

[dawn quiver]

woudl you say

its possible to do the same with pygame

:D

[next estuary]

lmao

I did it in 2d with pygame first

sec

[dawn quiver]

i did a lot of 2d games with pygame

like 30

only fully finished 7 or 8 tho lmao

so i was thinking

i could do 3d

[dawn quiver]

thats a nice game

wait lemme show what im working on

@next estuary

i tried so many things for a moving background lmfao

like

so many

such as changing the matrix

so if i clikc right

the list will pop and append

but that would look trash af

eventually i got the idea

of just

making a new tile with the changed position

now the idea was correct

but my implementation was fucked

at first it accelerated

cause i forgot to set the relative x value back to 0

later i figuered it out

and it worked

[next estuary]

I use move_ip on the player so everything moves relative to the player

Old video so it has a bug where the screen doesn't go down until farther down

[limber veldt]

I need to learn how that works, the move_ip() thing

[limber veldt]

It's only been two days and I'm already tired of rain rain rain

[opaque fox]

Hey yo

Do you know how to make platforms

I already made the jumping mechanism

Let me show you

`if player.IsJump is False and key_pressed[pygame.K_SPACE]:
player.IsJump = True

    if player.IsJump is True:
        player.PlayerY -= player.PlayerYvel*2
        player.PlayerYvel -= player.Gravity
        
        if player.PlayerYvel < -10:
            player.IsJump = False
            player.PlayerYvel = 10`

IsJump = False

`class Player:
def init(self, PlayerX, PlayerY, width, height):
self.PlayerX = PlayerX
self.PlayerY = PlayerY
self.width = width
self.height = height
self.PlayerVel = 5
self.PlayerYvel = 10
self.Gravity = 0.5
self.IsJump = False
self.OnPlat = False

def Player_Creation(self, WIN):
    PlayerRect = pygame.Rect(player.PlayerX, player.PlayerY, player.width, player.height)
    Player = pygame.draw.rect(WIN, (255, 0, 0), PlayerRect)

def Player_Movement(self, WIN):
    key_pressed = pygame.key.get_pressed()

    if key_pressed[pygame.K_d] and player.PlayerX <= 765:
        player.PlayerX += player.PlayerVel

    if key_pressed[pygame.K_a] and player.PlayerX >= 5:
        player.PlayerX -= player.PlayerVel

    
        
    

    if player.IsJump is False and key_pressed[pygame.K_SPACE]:
        player.IsJump = True

    if player.IsJump is True:
        player.PlayerY -= player.PlayerYvel*2
        player.PlayerYvel -= player.Gravity
        
        if player.PlayerYvel < -10:
            player.IsJump = False
            player.PlayerYvel = 10`

Attract mode demo, not bad:

[limber veldt]

Just a matter of adding more behaviors to the enemies if the game is in demo mode

And shooting at just the right times

Still a bit of work in progress but close!

[agile ore]

goodluck sir

[dawn quiver]

Nice!

[teal ember]

does anyone know optimizations for multi body collision

looked up spatial partitioning methods like sweep and prune but i am having trouble understanding those

sweep and prune seems simple to implement

i thought it was more complex

Python Gamedev (for an Amiga game)

Not exactly a game implemented in Python, but some part of the project I worked on for 3 years are heavily based on a Python toolchain of my own.
This is the game : Athanor 2, for the Amiga computer (a computer that went to the market circa 1985, powered by a 16/32bits CPU running at 7.14MHz)

The game itself is entirely written in C, BUT :

• all the texts, graphics, musics and audio fx are pre-processed from modern formats (png, wav, ...) to a more suitable format, thanks to a set of Python tools I created
• the scenario & game logic was written in a very simple (yet turing-complete) language (made of basicaly 3 or 4 instructions). I relied on Python to transpile this game logic scripts into C.

This is what the game looks like (it should be available in a matter of weeks now) :
https://www.youtube.com/watch?v=3H4jfGa0ImU

the Python transpiler takes the langage on the left, here, and translates it into C, on the right :

approximately 30% of the C source code of the game is generated by a Python script

the texts (descriptions, dialogs...) are processed by Python, using many of the available tools, including a hyphenation module that is very handy (the game is both in French & English, and I wanted to pre-hyphenate the texts, so that the Amiga don't have to do it)

it reaaaaally easier to deal with encoding in Python (the original files are in DOS CP 437 for some reasons, and the Amiga works in Latin-1)

all the graphics & audio files were processed by calling either Image Magick or SOX, using popen ❤️

and I relied on a CRC16 Python module to generate unique IDs (needed that to make the save/load routine future-proof)

my conclusion
Even for retro-machine gamedev, Python is a real asset!

(some more technical details about the native plaftorm here : https://www.amigalife.org/index.php?topic=158.0)

[limber veldt]

Python is great for retro gamedev

I've done a few big retro arcades with python

This current project is probably my most completed

Or most like the original

[snow hill]

like this one ?

Salem OK (@salem_ok)

Bug Fixing and refactoring this weekend, so instead of posting new features, I offer you a race between the original #AtariST Drones (Yellow and Green) and the PySprint Drones I have written from scratch, by just eyeballing the original game (Red and Blue). Close enough? #pygame https://t.co/QUH6FlVAKT

Twitter · Jun 27, 2021, 7:58 AM

[limber veldt]

hah, that was a fun one, would be fun to remake too

That's hard to do, those drones

How are they finding the path?

[dawn quiver]

woah thats realy cool

[dawn quiver]

Path finding algorithims

[limber veldt]

Oh really?

[dawn quiver]

Mhm

[limber veldt]

Like I know that already

But that doesn't tell me anything

[dawn quiver]

Well then

Why ask?

You could just learn

ML

Instead of saying you dont know how they are finding the path

😄

[limber veldt]

There are at least a dozen path finding algs, path finding algs doesn't tell me shit

[dawn quiver]

Its up to you to pick one?

[limber veldt]

I asked about what he/she was using

[snow hill]

the source code is here, it prolly starts with some sort of collision detection, then a routine to find the best way to avoid the collision (against the track borders)

[limber veldt]

Not what I'm picking

[snow hill]

https://github.com/salem-ok/PySprint

[dawn quiver]

Well why dont you go learn some DSA, ML and then come back so that you woudl know what to do

[limber veldt]

I know what to do

See

That's where you're confused

I'm not asking for help

[teal ember]

chillll

[limber veldt]

Especially not yours

[dawn quiver]

Okay

your loss then

For someone who only knows game dev thats pretty cocky

And that too a 2d arcade game being all they made

[limber veldt]

I know about path finding algs, I've coded some of them myself

[dawn quiver]

Well then, shoudnt you know how they are finding the path? Or do you just want to know the specific alg they are using 🙄

[snow hill]

yeah, calm down, folks 🙂

[dawn quiver]

I guess theres no point arguing with that person

Ill stop wasting my time

[limber veldt]

Stop wasting my time, too

Thanks

I asked someone what they were using and you have some cocky reply "path finding", like no shit sherlock

You're a genius

[snow hill]

i'm not sure there's a path finder, here

probably it's far more naive than that, something like "trying to avoid the walls in the next meters"

the track is described as 2D vectors, easy to check is there's a collision incoming

[teal ember]

pretty sure a path finding algo will look too janky

unless you lerp the shit out of it

[limber veldt]

Looks like it's just aiming for the next gate all the time

While avoiding walls

Which gives some insight as to how it's working

The track has multiple 'gates'

And the AIs are always just driving to the next one with some adjustable params along the way in their personalities

I've read and heard it a few times, the simpler the better for AIs

I totally don't know how to code game AIs

[limber veldt]

For that demo mode, I created an object that runs it and triggers events based on the object's age

I don't know how else to schedule things

So it's basically a chain of if self.age == statements followed by things to do

[opaque fox]

Still didn't get it pal

How can you make a platform in pygame

I already made the platform

And the collusion of it

class Platform:
def init(self, PlatformX, PlatformY, width, height):
self.PlatformX = PlatformX
self.PlatformY = PlatformY
self.width = width
self.height = height

def Platform_Creation(self, WIN):
    self.PlatformRect = pygame.Rect(platform.PlatformX, platform.PlatformY, platform.width, platform.height)
    self.Platform = pygame.draw.rect(WIN, (GREEN), platform.PlatformRect)

def Platform_Collusion(self, WIN):
    global On_Plat
    PlayerRect = pygame.Rect(player.PlayerX, player.PlayerY, player.width, player.height)
    Player = pygame.draw.rect(WIN, (255, 0, 0), PlayerRect)
    
    if platform.PlatformRect.colliderect(PlayerRect):
        print('platform has been touched')

Right now it's printing a string value whenever a collusion happens

So how to make something stand on it?

[dawn quiver]

You would need to stop the x or y value from proceeding

its simple

normally when you click right/left it moves x by a certain amount

so you just need to say, that when its colliding your relative x becomes 0

for example

isntead of directly changing the value of x

just change some other value

let me show u the pseudo code

relative_x = 0
x = 300

if clicking right:
    relative_x += 3
elif clicking left:
    relaive_x -= 3

x += realive_x

screen.blit(image, (x, y))

Now what you need to do is basically before blitting it, you need to do one last "check"

relative_x = 0
x = 300

if clicking right:
    relative_x += 3
elif clicking left:
    relaive_x -= 3

# Last check
if colliding with wall:
    relative_x = 0

x += realive_x

screen.blit(image, (x, y))

Now guess what would happen

now the characters x position woudnt change when colliding with the wall

as for jump mechanics

Basically, theres a 'main' loop which runs most games
And we need to define how many times the loop, loops in a second
This called as the FPS, lets say the FPS is 60
During a jump, the y position of the character increasing by a few pixels through every time it goes through the loop(every iteration)

And once the y position has reached a certain maximum value after its initial point, we just make character STOP

Now you may be wondering, if the character has stopped, why does it fall down after a jump and reach the ground?
Well this is because throughout the entire loop, we are infinetly reducing the characters y position
and the reason it doesnt go below the ground, is that we say that it cant go through a certain 'floor'

This is how a jump works in a 2d game
Try reading the pygame docs and implement it :)

in cases like this i recommend reading some nice source code of a platformer

and get to see how others do it as well

https://github.com/formazione/platformerRuss/blob/main/platformer.py

This is some good source code

[limber veldt]

Uh oh, everyone be quiet, the genius is talking...oh wait, there wasn't anyone typing anyway, carry on

[crisp belfry]

hi

need help in making discord bot

need testers too

dm me for any testers and helpers

[opaque fox]

Well

You first have to make a function

def Player_Movement():

inside it

Do as follow

key_pressed = pygame.key.get_pressed()

if key_pressed[pygame.K_RIGHT]:
(Your player X value) += (The amount of pixels you want to change)

Easy

@dawn quiverYou first have to define a function that will controll all of this

[valid seal]

Can you not update the colour of SpriteSolidColor? Inside on_update I've changed the colour of a sprite within an inner sprite list using self.grid_sprite_list[column][row].color = color. And that works just fine, no errors or anything.
However, when I try to then draw the sprite, no changes visually appear even though the attribute now has another colour
Anyone know how I can fix this?

Solved: By using a Sprite instead, with the image being a white square, changing the color attribute just tints the white to whatever colour you want it to be

(this is in arcade just to be clear)

[thin iris]

Guys Can I use ursina for making minecraft?

[slim parcel]

I've done it on a small scale but I wouldn't simply because ursina uses voxels and they tend to be pretty laggy on a large scale but small worlds and building is perfect with ursina

[kindred badge]

I mean then can I use kivy?

[slim parcel]

ive never personally used kivy so idk

Im not hating on ursina its still good for game developement

[kindred badge]

I have used but I think its only used moblile apps and fast 2D and 3D games

[slim parcel]

ursina is better for 3d games in my opinion

[kindred badge]

but the problem is if you wanna develop games like Minecraft you have to use Ursina because it has better support for 3D games.(and apps maybe!)

but yeah thnx @slim parcel

[slim parcel]

yeah i wish there were more options

[kindred badge]

I guess you are having wrong opinion(no offense)

coz I just googled for great 3d game dev and there is showed this

[slim parcel]

what did you find

[kindred badge]

see this

[slim parcel]

oh

wow i guess there are more options

[kindred badge]

lemme give a link to the article

[slim parcel]

ok

[kindred badge]

[kindred badge]

check it out!

[slim parcel]

definitely gonna use some of these

thanks @kindred badge

Is there a builder (possibly web based) that I can use to build Pygame GUIs? Then after I finish the GUI it'll give me the co-ords of all the shapes i drew?

Im asking because i've spent the past 2 days building a GUI, most of which were spent tweaking co ords

this is starting to get cumbersome and time consuming so im wondering if there's a way or a tool that I can use to speed tihngs up?

[slim parcel]

are you using classes for the objects

[sacred vault]

yes

[slim parcel]

ok im trying to find some stuff rn

have you tried blender

[sacred vault]

no. Blender and Pygame use co ords differently right?

[slim parcel]

on the web it notes them being compatible

[tranquil girder]

yes, but you have to make it the proper way with chunks and stuff if you want it to run fast, not like in the famous video tutorial

[sacred vault]

ah ok.

[void flame]

why would u make an game in python and not just use unity and cs, what r the pros?

[tranquil girder]

you can fix bugs yourself instead of being the mercy of unity
you don't have to use a slow and unstable editor
less waiting for compilation and asset importing
you can control the asset pipeline yourself
you might like python better than c#
unity isn't free or open source
you have access to the whole python ecosystem, all the packages

[teal ember]

also making things from bare minimum is fun

[tranquil girder]

And even just economically. There's a lot of waiting when making bigger projects. And if every member of your team have to spend an hour every day just waiting for unity to import assets and such, that's a lot of money wasted. You'll need a really beefy computer

Of course, there's a lot of upsides to unity too, like cross platform support

[void flame]

wdym unity isnt free

if your company earns more than a certain amount of money, you have to subscribe

But what i do now is i'll make these if statements like if game-start equals True then you can do all the code for that slide and like if you press the button that equals play or something and then it will have all the code for that slide. This is my code from repl.it (just an online website to code) https://replit.com/@815398/data-base-7#main.py. (the password is just 123). I am dutch by the way if you don't understand the words

so the other way is for example; if start_game == False: and then the code for that slide. and then if you make a button and you click on it it wil become true. and then you can type else: and the code for the next slide

hope that might help

Guys does this work?

import pygame as py

py.init()
size = (500, 300)
screen = py.display_setmode(size)

while True:
for ev in py.event.get():
if ev.type == py.MOUSEBUTTONUP:
pos = py.mouse.get_pos()
col = (0, 255, 255)
py.draw.circle(
screen, col, pos, 20, 5
)
py.display.update()

🤯

[nocturne nova]

screen = py.display_setmode(size)

that has an error it says that pygame has no attribute 'display_setmode'

import pygame as py

py.init()
SCREEN_WIDTH = 500
SCREEN_HEIGHT = 300
display_output = [SCREEN_WIDTH, SCREEN_HEIGHT]

screen = py.display.set_mode((SCREEN_WIDTH, SCREEN_HEIGHT))
while True:
for ev in py.event.get():
if ev.type == py.MOUSEBUTTONUP:
pos = py.mouse.get_pos()
col = (0, 255, 255)
py.draw.circle(
screen, col, pos, 20, 5
)
py.display.update()

this does work

Are there any libraries like PyMem or ReadWriteMemory, but Linux compatible?

[rigid parrot]

RWM's setup.py classifier lists 'Operating System :: POSIX :: Linux'

but their documentation is rather lacklustre

[brisk monolith]

Thanks

[brisk monolith]

So basically you have divided your game code into different modules right?

I've my project submission on 6 and I've created the text based version but I'm struggling to add graphics because I haven't learnt OOP and the pygame button tutorials on YouTube uses OOP. All I need is gui buttons and display for scoreboard and now currently I'm thinking of using tkinter cause it contains builtin button

[torn elm]

so can you help me understand why this doesn't work?:

    joysticks = []
    for i in range(pygame.joystick.get_count()):
        joysticks.append(pygame.joystick.Joystick(i))
    for joystick in joysticks:
        pygame.joystick.init()
        print(pygame.joystick.get_init())```
let me explain a bit more
it does not give an error but also isn't moving my character like it should from this part:
```py
            if event.type == pygame.JOYAXISMOTION:
                analog_keys[event.axis] = event.value
                print(analog_keys)
                if abs(analog_keys[0]) > .4:
                    if analog_keys[0] < -.7 and player.x - player_vel > 0:
                        player.x -= 7
                    else:
                        continue
                    if analog_keys[0] < .7 and player.x + player_vel + player.get_width() < WIDTH:
                        player.x += 7```
here is full code:
python file: https://hatebin.com/jwjvpedeng
json file: https://hatebin.com/dgqtvahqqr

I have to go but please respond with possible solutions and I will come back and respond ASAP

someone on stack overflow told me to try this:

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                run = False

        if joysticks:
            joystick = joysticks[0]
            axis_x, axis_y = (joystick.get_axis(0), joystick.get_axis(1))
            if abs(axis_x) > 0.1:
                player.x += 7 * axis_x
            if abs(axis_y) > 0.1:
                player.y += 7 * axis_y```
so I will be trying that as well

Thank you kind sir or ma'am

[dawn quiver]

Hey

[rich coral]

is there some way i can call c# events, such as Unity functions, from python? I would like to use python's NEAT play a game I made

[proper peak]

So you have a Unity game and you want to use a Python AI with it? From what google tells me, it's possible (unofficially) to script Unity with Python, so that'd probably be the way to go.

[autumn pilot]

When using GDB and attaching to a process it freezes it, is it possible to avoid this?

[willow canyon]

Thanks, ill take a look !

[torn elm]

nvm

so I'm trying to make a boost functionality to TechwithTim's space invaders pygame video but everytime I click the boost button it crashes the game from over loading it here is my code:

       if left_trigger_axis > 0:
            boost = True
            while boost == True:
                t = 15
                time.sleep(1)
                t -= 1
                print(t)
                if t > 0:
                    player_vel = 15
                elif t <= 0:
                    player_vel = 7
                    boost = False ```
yes I'm using a controller the button works fine its the boost parts that don't work
the print always prints 14

[last moon]

t = 15
time.sleep(1)
t -= 1```
you're overwriting `t` each loop

(also while boost == True: can just be written as while boost)

[patent elk]

Hi guys I have a game compilation related question

Can someone help me out? 😄

[last moon]

also also it won't do what you want it to, because you're running the loop inside your game loop, this loop will run first, then continue to the next update cycle
on top of that time.sleep blocks your program from running anything so your game wont update

easiest fix would be to set t as a higher value, (in your game loop) check if the trigger is > 0, check what value t is, set player speed and decrement t
or you could also set up a async timer (or compare time between frames) which will decrement t every x seconds

[torn torrent]

Can you take a look at my game? There will be an update today!

Hey

I wanted help in pygame

import os
import pygame

WIDTH, HEIGHT = 900, 500
WIN = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Testing")

CYAN = 60, 123, 240

FPS = 60

YELLOW_SPACESHIP_IMAGE = pygame.image.load
(os.path.join('spaceship_yellow.png'))

RED_SPACESHIP_IMAGE = pygame.image.load
(os.path.join('spaceship_red.png'))

def draw_window():
WIN.fill(CYAN)
WIN.blit(YELLOW_SPACESHIP_IMAGE, 300,100 )
pygame.display.update()

def main():
clock = pygame.time.Clock()
run = True
while run:
clock.tick(FPS)
for event in pygame.event.get():
if event.type == pygame.QUIT:
run = False

    `draw_window()`

`pygame.quit()`

if __name__ == '__main__':
main()

win.blit isn't working

what's wrong in this ?

[sinful lodge]

wuts the erorr

[dawn quiver]

one sec i will send

[sinful lodge]

um add a pygame.init()

[dawn quiver]

ok

[sinful lodge]

after import pygame

does it work

[dawn quiver]

i will send error msg

one sec

[dawn quiver]

umm this is the error

code

[sinful lodge]

oh

i think it should be WIN.blit(image,(300,100))

[dawn quiver]

no

not working sir/madam

[sinful lodge]

also

[sinful lodge]

pygame.image.load()

i think theres a

break or smth

can u retype that

pygame.image.load(os.path.join('spaceship_red.png'))

do the same for yellow spaceship

[dawn quiver]

it is thinking 300 is also the source

[sinful lodge]

no

cuz u defined yellow_spaceship_image as pygame.image.load

[dawn quiver]

ok

[sinful lodge]

YELLOW_SPACESHIP_IMAGE =

[dawn quiver]

Thanks sir/madam

its working

thanks a lot @sinful lodge sir/madam

[sinful lodge]

np

[meager pendant]

can a good 2d game be made with python?

[teal ember]

yes

[last moon]

https://learn.arcade.academy/ and https://arcade.academy/ are great places to start

[sinful lodge]

no

sadly python is limited to printing outputs in consoles

if you want to make a good game

learn something like brainf

or assembly

[blissful cape]

hey guys is there anyone who might be able to help me out with a problem i am struggling with in pygame?

[tranquil girder]

how would they know without knowing what the problem is?

[torn elm]

so I have a new problem when I was trying to make it so the player couldn't fly off the screen I made them get stuck to the wall when they touched it any idea why this happened?:

        axis_x, axis_y = (joystick.get_axis(0), joystick.get_axis(1))
        right_trigger_axis = (joystick.get_axis(5))
        left_trigger_axis = (joystick.get_axis(4))
        if abs(axis_x) > 0.1 and player.x - player.vel > 0 and player.x + player.vel + player.get_width() < WIDTH:
            player.x += round(player.vel * axis_x)
        if abs(axis_y) > 0.1 and player.y - player.vel > 0 and player.y + player.vel + player.get_height() + 15 < HEIGHT:
            player.y += round(player.vel * axis_y)

if you couldn't tell already this is in pygame

please @ me if/when you respond

[blissful cape]

is there anyone who could help me with making my left mouse click also a key in my game right now i can only make keyboard controls work but i cant find a way to add my left mouse click

if you can help me pleas @ me or send me a dm

[torn elm]

so this is what I did in my pygame for a main menu type thing:

            if event.type == pygame.MOUSEBUTTONDOWN:
                #what you want to happen

[blissful cape]

yes look

 while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE and game_active:
                bird_movement = 0
                bird_movement -= 7
                flap_sound.play()
            if event.key == pygame.K_SPACE and game_active == False:
                game_active = True
                pipe_list.clear()
                bird_rect.center = (100, 512)
                bird_movement = 0
                score = 0

[torn elm]

but I believe this is every button on the mouse though

so instead of KEYDOWN do MOUSEBUTTONDOWN

[blissful cape]

then i get this error

if event.key == pygame.MOUSEBUTTONDOWN and game_active:
AttributeError: 'Event' object has no attribute 'key'

[torn elm]

it should be event.type as well sorry

[blissful cape]

so what do i change

?

i want space and left click to both work

[torn elm]

 while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            if game_active:
                bird_movement = 0
                bird_movement -= 7
                flap_sound.play()
            if not game_active:
                game_active = True
                pipe_list.clear()
                bird_rect.center = (100, 512)
                bird_movement = 0
                score = 0

I believe that should work

oh wait

let me edit that and fix something

there we go

[blissful cape]

lemme try

yeah

that works

but how do i

mka

make

space and mouse work?

so i can use both

[torn elm]

make another one with the space bar

[blissful cape]

so like i had before?

[torn elm]

yes

[blissful cape]

doesnt work

what do you mean

make another one

i copy pasted my old code

underneath it

[torn elm]

so it should be this:

 while True:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            sys.exit()
        if event.type == pygame.MOUSEBUTTONDOWN:
            if game_active:
                bird_movement = 0
                bird_movement -= 7
                flap_sound.play()
            if not game_active:
                game_active = True
                pipe_list.clear()
                bird_rect.center = (100, 512)
                bird_movement = 0
                score = 0
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_SPACE and game_active:
                bird_movement = 0
                bird_movement -= 7
                flap_sound.play()
            if event.key == pygame.K_SPACE and game_active == False:
                game_active = True
                pipe_list.clear()
                bird_rect.center = (100, 512)
                bird_movement = 0
                score = 0

I believe

[blissful cape]

this makes it work

but

also right click works now

and i only want left click to work

[sharp lily]

@blissful cape check the result of event.button

1 - left click
2 - middle click
3 - right click
4 - scroll up
5 - scroll down

[blissful cape]

Where is the event.button?

[sharp lily]

Check that field when you check if event.type is mouse button down to determine which mouse button it is

And you can only perform the action if the left button is clicked

[cold owl]

hi

[proud remnant]

hi

[blissful cape]

Yeah I did this but then I changed if game_Active to if event.button == 1: but idk if that’s bad that I removed the game_active

[sharp lily]

@blissful cape you can always use and to check both ¯_(ツ)_/¯

[blissful cape]

how i do this @sharp lily i dont understnad what you are saying

[sharp lily]

if game_active and event.button == 1:

The if statement will only execute if both expressions on each side of the “and” are true.

[sinful lodge]

tips for improving/maximizing pygame performance?

[teal ember]

cython and pypy

and code with a good time complexity

[proper peak]

does pygame even work with pypy?

[teal ember]

hmm not sure

but it does with cython

[proper peak]

I think it refused to launch when I tried, but that was back on Pygame 1.*

[teal ember]

from what i have seen

looked it up, apparently it doesnt

[wicked lintel]

I am trying to use arcade, but when trying to impot it, it throws the error that there is no lib called 'GLU'
i have arcade itself installed (duh), as well as opengl 4.6, mesa-utils and freeglut-dev.
i tried following tutorial online, but it still doesn't work, it continues to throw said error

[wanton lodge]

should i use ijkl controls

for left handers

[wicked lintel]

no

don't

[teal ember]

wasd

and arrow keys

please

[wicked lintel]

(I'm a lefthander)

[teal ember]

who uses ijkl

[wanton lodge]

what's wrong with ijkl

u can use right hand to do movements

[teal ember]

you use wasd

with left hands

[wicked lintel]

me, when having ground control for planes in trailmakers. but thats it. (wasd for pitch and roll, ikjl for car like controls)

[teal ember]

not ijkl

[wanton lodge]

i know

[wicked lintel]

just use wasd

[wanton lodge]

wouldn't the game control be worse if the main hand is left and you're using wasd?

[tired steppe]

Hi

[wicked lintel]

no

[wanton lodge]

have you tried ijkl

[wicked lintel]

bc we use the mouse with the right hand still

[wanton lodge]

ok sure

[wicked lintel]

at least most of us. the others can go to hell figure it out for themselves

[wanton lodge]

i thought left handed uses left hand to control mouse

[wicked lintel]

nope

[wicked lintel]

anyone having an idea?

... it works fine, when executing it via the terminal

just not via pycharm

[crisp junco]

use vscode , pycharm sucks (atleast for me)

[wicked lintel]

for me, none work propperly

both are throwing said error

[kind chasm]

Hi everyone

Anyone making a game as side project right now?

[lament condor]

i am

[kind chasm]

What tech stack?

Like what modules are you using?

Im using django + html + bootstrap css

[lament condor]

python and not much else

it's a text based game

gonna be playable in the terminal

[kind chasm]

ah nice

Mines basically a text based but you click your way through

its about robots

[lament condor]

nice

[kind chasm]

Do you have a leveling up feature?

Im currently coding that now.

[lament condor]

nah i don't think i'll add that

it's kinda based off this game (gimme a sec)

http://textadventures.co.uk/games/view/7nwoee9ope2_hvfrx8kjvw/night-house

which was pretty dope

[kind chasm]

very scary lol

Mines a little less scary

[lament condor]

same here, but im not even making the story or anything yet

what i'm making is the game system itself and then i can use that to make as many maps/levels as i want

[kind chasm]

Mines similar to pokemon battle but with robots basically.

Right

[lament condor]

cool

[kind chasm]

So basically the system can be for turn based anything

like final fantasy or pokemon style

I am still thinking about how it will work though.. because idk if i really need websockets for the battles

For sure I want ajax request though because I don't want the page to re-render every time

[chilly vine]

https://paste.pythondiscord.com/musasoduse.py
In this pygame program, how do I make the scroll wheel flash last for three frames consistently? Right now, sometimes it lasts for 4 frames.
The relevant parts are from lines 42 to 55 and lines 129 to 141.
Also I don’t want to use pygame.time.delay because it causes 100% CPU core usage
*I changed the flash time to 42 because that's right between 33.3 milliseconds and 50 milliseconds, 2 frames and 3 frames. It seems like it improved it, but I'm still not sure if it's a good solution.

[kind chasm]

Are you saying: waited_time = pygame_time_wait(1)
is 4 frames?

Which function specifically is it?

@chilly vine

[opaque crow]

im new to using pygame on idle python

does anyone have tips

[kind chasm]

I would copy and paste an example

If I were you

[opaque crow]

wdym

from pygame.org?

im guessing so

[chilly vine]

50 milliseconds is 3 frames

But if I have the flash last that long, sometimes it's shown for 4 frames

[frank marsh]

What do you guys use to develop the game other than python itself (what do you do for the visual and audio part) ping me. (Im a little new to game development)

[last moon]

You can use arcade, pyglet, pygame, panda3d, etc, for games/visuals. Most graphical libraries included graphics + audio

[static dew]

Why doesn't my arrow keys work? https://paste.pythondiscord.com/oqoyogunoz.py

[spring carbon]

Umm... because you are always drawing at (SCREEN_WIDTH/2, SCREEN_HEIGHT/2)?

I may have got it wrong tho 😬

[static dew]

👍 I edited it to: screen.blit(player.surf, player.rect)

It's always such simple mistakes that I always overlook 🤣

[frank marsh]

THANKS

I REALLY NEEDED SOMETHING LIKE THAT

e

Does blender work too?

[livid belfry]

Blender just makes 3d graphics and animations

[last moon]

I can never remember the name of the library for the life of me 😄 but there is a framework for working with blender

I’d also assume you’d be able to load models in the 3D libraries but I’m not sure about that

[proud remnant]

You can load blender projects with pyunity

[wicked lintel]

how can i change the scaling algorithm in arcade to none?
it uses cubic (or bipolar) as default, but I'm making a pixel art game, so everything just looks reallly blurry

[frank marsh]

Ah I see

so anything you people would recommend for my FIRST graphical library for python?

[last moon]

https://arcade.academy/ and https://learn.arcade.academy/ are great places to start

[last moon]

Also if you’re working with 3D models/animations it looks like panda3d has native support for it

[frank marsh]

Oh okay thanks

im first going to complete OOP in my course

[proud remnant]

i recommend pygame

because thats what i use

[frank marsh]

Oh okay

not arcade?

ive heard arcade is better?

[lament prairie]

Hello everyone, I am coding in pygame and I would like to know how to make an image resize to fit the screen size please?

[last moon]

it's somewhat subjective but arcade's docs are a lot nicer

that being said, you'll find a lot more tutorials/examples for pygame

[frank marsh]

oh okay

I will have to learn OOP for this before right?

@last moon

[last moon]

You don’t have to, but a strong foundation in it will help a lot

[frank marsh]

okay

thats im going to do now

e

[proper peak]

You need the NEAREST interpolation then.

searching in the docs, I see that the Context objects (representing an OpenGL context) have interpolation modes

where do you set it, hmm...

@wicked lintelAh, there we go:
https://arcade.academy/tutorials/edge_artifacts/index.html?highlight=nearest#aligning-to-the-nearest-pixel

If instead you want a pixel-look, you can use a different filter called “nearest.” This filter also reduces issues with edge artifacts. First, import the filters at the top of your program:

from pyglet.gl import GL_NEAREST

Then, in your on_draw update the drawing of your sprites with the filter:

def on_draw(self):
    self.my_sprite_list.draw(filter=GL_NEAREST)

[wicked lintel]

ah thanks :3

i already figured that i needed nearest, but i didn't know how to get it to draw like that

(nearest and none are the same right?)

[proper peak]

well, the only way to not have any interpolation is to not resize your textures at all 😛

if you want the texture to "look the same but larger", that's nearest

[wicked lintel]

yee, worked with pixel art before

worked. thanks a lot :3

[severe saffron]

ive seen point sampling called 'nearest', 'pixel', 'none'

nearest neighbour for downscaling

[mental jetty]

Does it have any way you can use a spritesheet in python without Json?

[twilit frost]

haii I want to make a 2d platformer kind a game for the web a simple game any suggestion on what frame workks i can use?

its fine if its javascript also

hi, im using pygame and im blitting an image but its not blitting anything but i have another for loop which when the coin (the image that isnt blitting) hits the player then the coin will disappear and print('col') i dont see the image on the screen but it is touching the coin and printing col?
code:

for f in foods:
        screen.blit(food,(f[1], f[2]))
        print(f)
        pass```

```py
#making the image move downwards
for j in range(10):
        for f in foods:
            f.y += j / 9
        pass
#when the player touches the coin
    for f in foods:
        if player_rect.colliderect(f):
            if enter == True:
                print('col')
                lives -= 1

@twilit frost Try arcade. Here's a tutorial for a simple platformer to get started: https://arcade.academy/examples/platform_tutorial/index.html

Question for everyone, I'm trying to improve API docs for the Arcade library. I've got this as a quick index to look up Arcade commands:

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

Any suggestions on improvements? Other libraries that do it better?

I have a question, I installed Kivy on vscode using pip, and it was when I have venv activated. So would Kivy continue to operate if I deactivate venv?

[twilit frost]

Can i use it on the web?

[dawn quiver]

Hello

Wassup

so whats the issu

e

so i copy pasted the thing but where do i start programming

You would need a text editor

or an IDE

i recommend starting off with sublime

as beginners do not need an IDE

elaborate

where does the script go?

i just tested by doing Print ("Hello World")

[sour bronze]

geany is amazing.

Chonk, what do you mean where did your script go?

[dawn quiver]

like if i do Print ("Hello World")

where does hello world go

where can i see it

you should be able to see a console

[sour bronze]

so like, let's instead of thinking about scripts

let's open up command prompt

and type python and hit enter

[dawn quiver]
