Here's my code. It detects if two rects collide and if so, it causes the two rects to disappear/not be shown. I've played around with time in all the lines here and I'm not sure where to put it. The two rects immediately disappear when they touch. I want it so you can see them collide inside of each other before they disappear. Where should I put time? Or is there another way?
if egg_rect.colliderect(fire_rect) or fire_rect.colliderect(egg_rect):
dragonspawn = True
egg_fert = False```If I put it before the if statement, it will slow the movement of the rects.

Camera movement in a 2d space?

how should I do it?
limber veldt
In general...instead of moving the player, camera movements move everything
So if your player stays in one place as you move, everything moves instead of the player
Or you can set up margins for your player to move around in and once outside those margins, move everything else (the camera)
lunar creek
i see where you are going with that but it seems pretty weird

pip definitely installed pygame, your screen shows it, but maybe not for the same python version to which your VSC is pointing
limber veldt
i see where you are going with that but it seems pretty weird
At its base, that's what viewports do, move everything else in relation to a player or some thing else
Racing games? Notice the player's car really never moves from the center of the screen, everything else moves
Top down or any kind of scrolling games. The player usually moves within some margin then everything else moves
It's almost always an illusion of player movement
And it's totally ok for something to be way outside the viewport boundaries and move into it while a player shows some walking animation, totally gets the illusion of player movement
Tile based scrolling usually has some tile management set up to move tiles into and out of the viewport

I found that the most comfy place use right hand controls. numpad 1 for thrust, left arrow for fire, down arrow for reverse, w for up, s for down, space for smartbomb, very closely mimics the game's original arcade cabinet layout
When first writing, I had coded go left and go right movement keys

screen just flickers like hell
This gets it close, maybe depends on your BG image to get it just right```py
import pygame
pygame.init()
screen = pygame.display.set_mode([900, 900])
bgrnd = pygame.image.load("background.png")
bgrnd_size = bgrnd.get_size()
bgrnd_rect = bgrnd.get_rect()
w,h = bgrnd_size
x = 0
y = 0
x1 = 0
y1 = -h
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
y1 += 5
if y1 > h:
y1 = -h
screen.blit(bgrnd, [x1, y1])
pygame.display.flip()
pygame.display.update()
pygame.quit()```
At some point, even through out the scrolling portion of your code, you're probably going to need two images of your background so you can scroll through one and slightly into the other so as to hide the transition back to the start of the image

That's because you are storing the resized image in self.size, instead you might want to do something like this:
_img_resized = pygame.transform.scale(pygame.image.load(_img).convert(), (_width, _height))

limber veldt
Is your object a class instance and does it have an update() method that's constantly running?
It's always convenient to give objects a self.age attribute and increment it in the object's update() method
If you have that, you can check the object's age when it moved down and put it back to its original position after its age reaches something higher than when it went down
Or you can start a pygame timer which is something a little more complicated that I haven't really learned yet
But you can make a timer that raises an event in the normal event loop then read it from there
young hill
Quick question about arcade if anyone could help. I have been trying to make text fade in over a second or two. I have a timer working fine, but getting the transparent value is a problem. I can initially set the text to be transparent (3 RGB Values, Transparent value), but i cant change it afterwards if that makes sense. (I cut parts of the code out as it was irreverent stuff like fonts)
self.text[0] = arcade.draw_text("Test", ((73, 151, 208, 255))) # In draw, works fine
self.text[counter].color = ((73, 151, 208, self.temp_time_text_new)) # in update, doesn't work for last value
self.text[counter].color only lets me change the first 3 values (which it does fine) but will not let me change the transparency value
printing self.text[counter].color only gives me the 3 rgb values, with no mention of the transparency

Such an open question, so many answers, no one reply is correct
First, you learn a programming language and learn how to code non-games. Then you go to school or take a course or spend years trying to learn all the math you need to do what seem like simple things that every game does
Got enemies on the screen and want them to follow a circle or a path or a square or avoid obstacles, math is the answer
Making games without any kind of AI is easy. Like tic tac toe for two players is a LOT easier than tic tac toe for 1 player vs the computer

i love pygame!
limber veldt
Me too!
Well, it's been great
I'm sure it has loads more functionality than what I'm even tapping into
Just in the sprite class alone
I'm only a month or two into learning pygame, kinda know python already
So I have my player ship. It's a sprite. Then, for my thruster, I have another sprite that keeps updating its position from the player position. To keep both sprites as tight as possible, they both need to update as close to the same time as possible. So my solution so far has been to simple add the thruster sprite to the player_group, since they will update at very close to the same time that way
But I'm not sure I like that solution
I suppose it's ok as long as I don't call groupcollide on the player_group but only on the player sprite
So use spritecollide() instead of groupcollide()
But there must be a better way to do my thruster, it took me quite a while to even come up with that solution
The 'drifty' relationship before I did that^ was driving me insane
So now I just blit the particles to that thruster surface instead of to the screen
Well, I don't blit them, pygame's group.draw() does for me
I'm thinking they have some optimizations under the hood there because the drawing is faster than I can do it manually

to create a window, but I have an error : ModuleNotFoundError: No module named 'ShowBase'
I just don't understand, I installed the version 64 bits (maybe that I had to install the 32 bits) please help me

How to remove an object in pygame when a event happens
Depends on how you've created/stored that object. A simple method could just be:
for event in pygame.event.get():
if event.type == #some type:

Depends what you need. Pygame has things Arcade doesn't and Arcade has things that pygame doesn't

opaque fox
Does anyone knows here how to make a game pause without freezing the whole window and how to restart the game?
limber veldt
Yeah...
Make a global variable, I called mine paused, and set it to False in your game's initialization...
paused = False
In your event loop check, ask for this and do this```py
if event.type== pygame.KEYDOWN and event.key == pygame.K_r:
paused = not paused
Just toggle, all it does is toggle paused from True to False and False to True every time I hit the R key
Then in my main while loop, something like this```py
if not paused:
draw_screen()
# and do whatever other updating things you're doing there
So it basically just stops your main while loop unless paused == False...that is
Anything in your main while loop that you don't want to pause, just don't include it in the if not paused: codeblock
And...by the way, I have some beautiful waves going here
Those are the things I always forget between projects, the trig tricks
Just don't do them enough, it's simple stuff
limber veldt
I think I've finally got it, an alg for one of my enemy behaviors
They're called swarmers, and like their name implies, they fly in a loose group until they get behind you then speed up to get in front by a few hundred pixels and, as they do, become a tighter group then fling themselves as a tighter group headfirst into the player
You better be shooting
So I have wave generator objects to calculate y positions and that generator has attributes for amplitude, period, and phase. So I can assign each of these swarmers its own wave function with unique attributes and, as they're in 'catch_up' mode, as when they're trying to pass the player from the rear, I can slowly constrain their self.amplitude
opaque fox
thx mate
limber veldt
So that no matter where they are in the group, they will come back to being closer together
I can even play with their phase to give them some more randomness
Pretty sure this is the kind of algorithm that was used on the original game
Something like that
Those guys were math wizkids
Nothing like the major 3d coding today, but pioneers coming up with how to make these enemies behave

They kinda look like boids
limber veldt
Yeah, they kinda do
I need to work out tightening them horizontally when they regroup as they drift apart along the x the longer they keep attacking
In a real game against them, that won't matter as much since the player is going to be shooting them or dying
So their lifespans won't be very long anyway
limber veldt
Now I've made them track a vertical target that slowly tracks the player's vertical position, giving the player a change to dodge their attacks but still have them come toward a player who doesn't dodge
We can see the vertical target tracking the player on the left, of course that won't be visible in the game
And I'm getting that annoying wobble at 0 vertical velocity, bug to be fixed
Already fixed
If player's not moving up or down and its y is greater than player y - 2 and less than player y + 2, velocity = 0

Some really awesome logic built up so far
Just getting the screen to scroll, enemies to keep pace with it, velocities to be waves or smooth ramps for smooth movements on everything
The next biggest hurdle is AIing the enemy landers who try picking up humans from the ground and ascending the screen then, once at the top, turn into mutants that just go fast wobbly paths straight at the player
But I pretty much have the enemies who depend entirely on the player's movements coded, they need some tweaks still

And I think they Square() class is supposed to be inheriting from something like...
okay so first its pygame.sprite.Sprite
and second, thats basically a way to make a group of sprites, so lets say you wanted a group of 10 blobs on the map with all the same properties:
class Enemy(pygame.sprite.Sprite):
def __init__(self, x, y):
pygame.sprite.Sprite.__init__(self)
self.image = pygame.image.load("Sprites/blob.png")
self.rect = self.image.get_rect()
self.rect.x = x
self.rect.y = y
self.move_direction = 1
self.move_counter = 0
def update(self):
self.rect.x += self.move_direction
self.move_counter += 1
if self.move_counter > 50:
self.move_direction *= -1
self.move_counter *= -1
and then to make a group out of it: blob_group = pygame.sprite.Group()
dawn quiver
I'm not sure what this is```py
self.rect = Rect(self.pos,self.size)
```but self....
You can draw a rectangle with pygame which creates a surface for yo with pygame.draw.rect() which will create a surface for you
But i think what you want is a rect to check for collision and position, so yes self.sur.get_rect() would return a rectangle that is basicallygoing to be invisible and always on top on a certain surface, using that you can get the position of the surface, and you can check for collision

@limber veldt
limber veldt
Of course, it can be used to draw on since it's a surface too, but get_rect() only to give self.rect a value since pygame sprites must have a rect

or rather
thats what get rect is
it was there regardless of get rect

AttributeError: 'EnemySwarmerSmall' object has no attribute 'rect'
That's an error in the draw for pygame, not my code. I just removed assigning a rect to one of my sprites
And by the way, the rect, more accurately, is an axis aligned bounding box defining a surface's rect size
We could probably use self.rect = pygame.draw.rect() but that's more than we need to simply create a surface
Which I'll have to try
But self.image needs to be the actual surface, self rectt is only the rect

limber veldt
And I have worked out how to do these things already, though I appreciate your effort
Yeah, when you call group.draw(), that's what pygame does
dawn quiver
limber veldt
The entire object, has no update(), no draw(), just the constructor for the things it must have plus addition to the grouppy class EnemySwarmerSmall(pygame.sprite.Sprite): def __init__(self, x, y, image): super().__init__() self.image = pygame.transform.scale(image, (6, 6)) self.rect = self.image.get_rect() self.rect.x = x self.rect.y = y tiny_enemies_group.add(self)
It's drawing will be handled by its parent
Well, it's position, I should say, where to draw : )
Pygame sprite group.draw() will draw him
And it's national eat your veggies day, get your brussel sprouts on!
limber veldt
Those scaled images are used in the game's minimap, they work really well but are a little too detailed for me
The original game's 'pixels' were actualy groups of four or maybe even nine pixels
So having a fairly detailed 6x6 actual pixels image is kind of too much detail to represent the original
sweet condor

golden gazelle
This is not specifically game development but it's something I'm using for a game, is there any good way to make coordinate based noise that is purely random. So just random noise that you can return to and have it be the same. The only way I can think of is each time combining the two coordinates of each pixel to a seed, and then using that seed for a random number generator to give me the value but it just seems a little clunky
limber veldt
The vertical behavior isn't too hard, just have them fly sine waves but their horizontal behavior depends on player speed and their current state

Oh wait
what your asking is the other way around ahah
You want to make some sort of noise with pixel coordinates?
golden gazelle
Yeah, instead of nice noise, I just want random but procedural
golden gazelle
No, I do still mean the map kind of noise, but just random instead of smooth like perlin
limber veldt
I tried doing some of that
The faster my player ship moves, the more it vibrates, kinda
But I couldn't work it out
Because the vibration was causing drift
golden gazelle
I'm using perlin for the proper terrain noise but I am trying to make a bit of noise to add trees to the world, and have the probability weighted in a sort of if randNoise(x, y) > threshold: #make a tree here
My issue is that if I did it purely randomly, when you return there would be different trees, but the world is also infinite so storing the locations isn't an option
Actually, don't worry. I've got it

Lovely day
I can get them fast and smooth pull outs at about ten feet, lower too but not as smooth
Gotta be more abrupt on the controls and lose smoothness
It's fun to lose some altitude on purpose that way though. Like come over something high-ish (my house for example) and roll into the drop to about a foot off the ground
Without changing forward velocity, makes it even smoother

or an easy way to do it with some library
limber veldt
Called UV Unwrapping, most 3d modeling software has tools for it
As far as I know, there is no code to automatically do it perfectly for every object every time, but auto unwrapping is a thing, just depends on where the cuts are made
Some corners of a convex shape can just be flattened out into 2d but not all of them, some will have to be cut to make seams

I'm unsure what you mean @verbal glade , but maybe you're creating two surfaces and want to swap between them or show one atop the other? Like a menu on a screen
verbal glade
Yeah. Doesn't it make more sense to swap between them?
limber veldt
Hmm, an if condition in a draw loop could tell us which screen to be using. but I'd have to work through that logic to see how to set it up
Plus, if it's a menu screen, it'll need user inputs

pos = pygame.mouse.get_pos()
deal_button.draw(menu_screen, BLUE)

screen.blit(menu_screen, [0, 0])
else: # normal game screen
for i in range(3):
for j in range(3):
grid[i][j].show()
pygame.display.update()```An exampleThe indenting is messed up...
So generally, one can swap between screen easily enough by blitting the new screen over the old but maybe there's a betterer way
That maybe the way to do it as I can't think of a way to use two actual display devices as we do with one like sopy screen = pygame.display.set_mode([width, height])
Blitting the menu surface over the screen is good
And I can enable/disable buttons on that screen
Maybe Tech with Tim, or someone else, has a video on game menus using pygame

Yes conditions work the best to make multiple screens
You just need to blit different things based on conditions

The meat of this color cycler, I still don't yet follow exactly what it's doingpy self.current_color = [x + (((y-x)/self.number_of_steps)*self.step) for x, y in zip(pygame.color.Color(self.base_color), pygame.color.Color(self.next_color))]
dawn quiver
ive never used zip so neither would i 
List comps are nice tho
:D
often used in pygame
limber veldt
So zip takes one value from each of the iterables and makes a two element list from them
pygame.color.Colrs are in the format of (R, G, B, A) so take the R from base color and R from next color
But the list comping throws me off
Here's the whole thing```py
class ColorCycler:
def init(self, color_list):
self.age = 0
self.change_every_x_seconds = 1
self.number_of_steps = self.change_every_x_seconds * FPS
self.step = 3
self.colors = itertools.cycle(color_list)
self.base_color = next(self.colors)
self.next_color = next(self.colors)
self.current_color = self.base_color
def update(self):
self.step += 3
if self.step < self.number_of_steps:
self.current_color = [x + (((y-x)/self.number_of_steps)*self.step) for x, y in zip(pygame.color.Color(self.base_color), pygame.color.Color(self.next_color))]
else:
self.step = 3
self.base_color = self.next_color
self.next_color = next(self.colors)
create instance of ColorCycler
self.color_cycler = ColorCycler(['white', 'white', 'white', 'orange', 'red'])
usage
def update(self):
self.color_cycler.update()
self.color = self.color_cycler.current_color

The effect is really nice with my lasers, along with the particle trails
I finally worked out how to make my ship stay at the margins but still be able to thrust away from them
If the ship is facing to the right,, self.rect.x -= 10 no matter what then use min/max to constrain the value
And the opposite for the ship facing to the left. self.rect.x += 10
Then set up one button to toggle ship facing left or ship facing right
That exactly mimics the original game's behavior
Like so. I'm not satisfied with the linear application of the thrust but it'll be easy to change with a better velocity += acceleration method
But, alas, I'm still stuck on trying to more closely mimic those damn swarmer behaviors
The flying saucer behaviors aren't too bad, kinda close to the original and have the same affect acting like the police of the chase
And I picked up on a little trick the original does...When using a smartbomb (kills everything on screen), it's actually deployed twice, one right after the other
The enemy shown in the thumb for that vid, the purple-ish star-shaaped thing in the upper left, the enemy pod, when shot breaks into 5 to 7 enemy swarmers. To make sure the smartbomb is effective against those, they just do two smartbombs in a row. One to kill the pod, the next to get any swarmers that spawned from the pods
And you can see it happen in the youtube vids of the game because the screen flashes white for a split second when each smartbomb happens
And, sure enough, we see two quick white flashes
Original: https://youtu.be/wAKxa5C9jHY?t=2937

We can see the laser color and the score color are using the same color cycler

can you see that little black dot below
thats the guy with guns head
only the guy with guns head is comming
😭
which means its not moving down further enough

class SpriteSheet():
def __init__(self, image):
self.sheet = image
def get_images(self, rows, columns, width, height, scale):

for i in range(rows):
for e in range(columns):

image.blit(self.sheet, (0, 0), ((e * width), ((i*fixer) * columns), width, height))
image = pygame.transform.scale(image, (width * scale, height * scale))
images.append(image)
fixer += 4
return images
A bad way to fix it but it works now lmao
im worried about the bottom rows tho 👀
limber veldt
Not the problem, looking closely at the sheet, we can see the lower row is drawn more up the image than the top row
dawn quiver
Not the problem, looking closely at the sheet, we can see the lower row is drawn...
also true
but ive kinda fixed it now
oh well
limber veldt
You have almost two full alpha blocks shown in the upper row and just over one in the bottom row
limber veldt
Above the player's head, that is...56
dawn quiver
aight
let me check
everything works like a charm
perfection
the fixer was the solution
just that
limber veldt
Yeah, fix it with your y calc
dawn quiver
its not fixer += 4, its fixer = 4
dawn quiver
Yeah, fix it with your y calc
anyways
i need to study now
rip, but gotta do what u gotta do
limber veldt
I should have gone to work today
dawn quiver
class SpriteSheet():
def __init__(self, image):
self.sheet = image
def get_images(self, rows, columns, width, height, scale):

image = pygame.Surface((width, height)).convert_alpha()
image.blit(self.sheet, (0, 0), ((e * width), ((i*fixer) * columns), width, height))
image = pygame.transform.scale(image, (width * scale, height * scale))
images.append(image)
return images
is the correct version
finally
lmao
5 hours
i spent 5 hours...

Stormy morning, good day to stay inside and work out these damn codes
limber veldt
Have fun with that, good times
Peace man
I suppose what I need is a little shady
But a MAME ROM of the original game
I have some of those stashed away from twenty years ago on an optical disk but I have no optical readers anymore, like none
That could certainly help me more closely analyze the enemys' behaviors
Godmode for it would be ideal

hi, i have an idea of a game, but i do not know how to implement it here's the idea:
*code = skill in game
*code to obtain skill
the player can create and edit code, giving another player his code
but i cannot make it possible because it'll be very unfair to the other player if they can mess up with the damages, things in game stats.
limber veldt
Godmode for it would be ideal
Welp, I've done exactly that
Now I can watch those damn swarmers in their natural habitat

hi, i have an idea of a game, but i do not know how to implement it here's the i...
You mean expecting the player to create the game as they go?
thats a great idea
But i recommend making commands to make things instead of expecting them to code
so instead of expecting them to use pygame, just use commands like create block
since that would make things more playable
and then they can add stats
but i cannot make it possible because it'll be very unfair to the other player if they can mess up with the damages, things in game stats.
Well just keep a stats cap, like dont allow them to keep damage over 'x' value
its a fun idea
and also make it such that they have to fight against someone as well
dude this is actually a good idea..
aight... thanks for the idea i gues.. .. :>
dawn quiver
ty for implementing that idea
:>
limber veldt
And it looks like they follow the one rule of all AIs...make it simple and let the nuances create character
Make it too complex and it starts feeling less organic

Hey got a question lads
How to start the game when I press the button
Or the text to be more specific
I need an answer
limber veldt
I'm so on these swarmers now...
opaque fox
I'm so on these swarmers now...
What?
limber veldt
Oh I'm just coding some enemy behaviors, they're called swarmers
The lurkers here probably getting tired of my talking about them but they've been quite a challenge
opaque fox
Oh I'm just coding some enemy behaviors, they're called swarmers
That looks
Cool
My enemies are dipshit
But now I gotta figure out how to make this main menu work
limber veldt
So, what keeps the swarmers ina swarm is not the result of them looking at each others positions, it's because of their x velocity and acceleration rules, much simpler than I thought
proper peak
that's probably the case, yes
though you can always go nuts and make them be boids 😛
limber veldt
I considered that route, looked at a couple of times in some vids
I got them working pretty good now just to add some randomness to their initial velocities
Yay, I can finally move on from them
They could use a tweaking here and there but good nuff for now
Getting them done in the hour or so since I deleted their entire update() method wouldn't have been possible had I not DLed the game and been able to really see what they're doing without a random player playing the game
dawn quiver
aight games comming together
the colours turned out to be perfect for a zombie shooter 😮

cerulean moat
whats the most easy to use game engine in python thats not pygame?
proper peak
arcade?
limber veldt
I said earlier, there are no tutorials for replicating classic arcade games but there's an exception...maybe not full tuts but Pacman has dozens of enemy behavior breakdowns scattered around the internets
limber veldt
I figured a really cool addition to my swarmer alg and how to make them focus on the player more instead of just randomly bobbing up and down within some margin on either side of the player...give them slightly more acceleration toward the player than away from him
Like when they're going up an are already above the player, apply more force to slow them down and turn them around than the force would be if he's going down and above the player
I need to give them some minimum vel[1] though
Because with that ^ setup, they will eventually match the y of the player and stay there...how often does a player stay completely still though?

the graphics look nice

yep the pixel art looks pretty neat

Hey @brave lake!

hello im new to python programming, but i know basics, im making a pygame, i have created a window and added an button image, but what i want is that when u press the button it spits out jokes, how can i do this? can someone quickly show me now??
limber veldt
First thing's first, learn to make a pygame button yet?
So far as it showing jokes when you ckick it, that's just putting a bunch of jokes in a list and using random.choice() on that list to choose one of them then display it on the screen

I was using pyinstaller for converting my python script into exe, but when executing the exe it crashes, no errors shown. pyinstaller --onefile -w filename.py this was the command i used. The script is only 1 python file, but it accesses images from another file. Is there something wrong with the command i used to convert it or is it something else. I am making a game with pygame.
limber veldt
I haven't tried converting to exe before but it seems like images in another file could be a problem
But who knows? I know nothing
potent scroll
But who knows? I know nothing
i tried py2exe, and it says that something is wrong with accessing fonts.
so for the fonts i had set it like this font1 = pygame.font.SysFont(None, 25)
formal basin
So far as it showing jokes when you ckick it, that's just putting a bunch of jok...
ok
limber veldt
There must be some way with those converters to properly deal with external resources, unfortunately, I don't know what that is
potent scroll
now i set it a ttf file instead of None, let me see if it works now.
limber veldt
Or use one of the names of a font from the list you get with thispy print(pygame.font.get_fonts())
Like sopy font = pygame.font.SysFont('comicsans', 22)
potent scroll
yep let me give it a try
potent scroll
@limber veldt Thanks for suggesting that, it did work now. It was the font that was messing it up. I used py2exe before and it did say it was something with the font. It works as an exe now.
limber veldt
Lovely

Just curious, are you on windows?

I was making an OS simulation inside of a game. Just for practicing around with different menus and stuff

Just curious, are you on windows?
ofcourse 😅
potent scroll
yeah giberish
limber veldt
They're like 130 characters long
potent scroll
true
potent scroll
Standard font names
limber veldt
Yeah
I wonder how widely available they are across different platforms. Like if I share a file with a linux, will they likely have the same fonts on their system? Probably not
Speaking of fonts, I gotta make my own for the alphabet and numbers 0 through 9
That's gonna be a grind
potent scroll
Let me try using one of those
limber veldt
They'll just be like 24x24 bitmaps
Maybe I can find a PNG sprite sheet of the fonts that I need...or make one myself
Maybe I'd rather have all resources internal
I dunno, it's too early
Internal would be easier to do the color fades that I need

I just wanted to thank everyone in this discord for their help on a project I was working with. It was basically a Rock Paper Scissors simulator that basically turned into a Final Fantasy Boss battle. Meanwhile, though, it logs how you play rock paper scissors to feed it into a simulator that can pit you against other players of the game to see who would win in million+ round games of rock paper scissors (who doesn't want to know that lol). It was far bigger than my prior beginner projects, and you all helped me work through some big hurdles!
I'm sure I'll ask more dumb questions, but I've learned a lot!
Maybe one day I'll figure out who to actually make the whole thing playable on someone else's computer!
limber veldt
gj, keep going
Thanks, getting closer
limber veldt
This will be a challenge, I have no idea how to animate that williams logo like that
limber veldt
Separate images or surfaces for the whole animation
dawn quiver
play each frame
limber veldt
Right
dawn quiver
at a higher frame rate
then
switch to a lower frame rate
for the rest of the code
also
you dont need to play each frame
just play a .gif file
¯_(ツ)_/¯
pygame allows .gif s
first you would need to make that into a gif tho
limber veldt
I won't be able to get it in a usable resolution though, well, it'll be a struggle
The original game had 292x240 res
But its pixels were the size of a 3x3 square of today's pixels
Maybe even a 4x4 square
dawn quiver
does pygame accept gifs for objects
thin violet
nive
limber veldt
Hmmm, I just need a way to turn an image into a list of pixel colors
opaque fox
Wait pygame allow gifs?
limber veldt
Just had to try an idea, it's not very convincing but it is a fill
tranquil girder
no, not animated gifs, just static ones.
ursina does though ;)
limber veldt
Just had to try an idea, it's not very convincing but it is a fill
Breadth first fill, not quite the same as the animation in the real game
It isn't really a lot of 3x3 pixels. I could put all their x/y locations in a list and order the list in the order I want to draw them
Needs touchups on the artwork but I made an editor for creating it, making changes won't be difficult
limber veldt
It isn't really a lot of 3x3 pixels. I could put all their x/y locations in a li...
Which is probably what they original game did
dawn quiver
looks good
limber veldt
Where there's a will, there's a way
Just a little change to my editor an a half hour of grinding clicking the pixels in the order I needed
There in the editor I have the cells (pixels) blown up to 8x8 actual pixels. In the game, they'll be 3x3 cells
Save the click location translated to grid coordinates, click, click, click, click, appending the location each time, eventually have a list of grid locations in the order that they were clicked
Iterate that list changing cell color as you go and viola! animated
I have a delay to slow it down more than usual for that animation, easy to change that though
limber veldt
Like so in the game, the beginning of a title screen
marble bison
Where there's a will, there's a way
loading screen also how do u guys make these games and animations
limber veldt
Painstakingly drawing on surfaces dot by dot, finding the coordinates of each dot...and so on, it's a lot of grinding
marble bison
Painstakingly drawing on surfaces dot by dot, finding the coordinates of each do...
yeah me and my friend wanna make a cool game
marble bison
Painstakingly drawing on surfaces dot by dot, finding the coordinates of each do...
and ur thing would make a nice cool loading skin
dawn quiver
okay so i was thinking about it
and
i realised
if you truly want to recreate the game
you cant just
gif the intro
you need to remake it
dawn quiver
Where there's a will, there's a way
yes something like this
limber veldt
Like so in the game, the beginning of a title screen
I got it pretty close right there
dawn quiver
Where there's a will, there's a way
how did you implement this btw
you just stated the position of each pixel?
that must have been hard
limber veldt
Well, I made an editor to draw the image then filled it while adding the coords one at time to a list. Then can iterate that list to redraw the image
So, I have 8x8 cells to click with the mouse. Left click makes the cell red, middle click makes it yellow, right click makes it white. Once i have an image drawn, I hit the W key and it prints a list of coords for all red cells and all yellow cells. Using that list, I can redraw the image on pixels instead of 8x8 cells
Here my current thing in the editor, done, now I just have to copy those coords to my game's attract mode object and write a little code to draw them on the screen where ever I want
dawn quiver

limber veldt
def update(self):
self.age += 1
self.color = self.color_cycler.current_color
# if self.color == [255.0, 8.25, 0.0, 255.0]:
# print(self.color, self.age)
if not self.age % 797:
self.run_once = False
def draw(self):
for coord in self.coord_list:
x = coord[0]
y = coord[1]
pygame.draw.line(screen, self.color, [self.x + x * 3 + 1, self.y + y * 3], [self.x + x * 3 + 1, self.y + y * 3 + 3], 3)
if not self.run_once:
pygame.time.delay(4)
pygame.display.flip()
self.run_once = True```The update() and draw() for the Williams animation
That's it
For that screen, I'm making the cells 3x3 pixels, hence the * 3 in the coords
So I'm not drawing every pixel, just drawing lines of width 3 that are 3 pixels long, that creates a 3x3 cell
According to those coords
So a little math and viola
The % 797 check, that just happens to be when the color cycler comes back to red after cycling about eight times. So I stop it there by setting a variable to True and retriggering the animation in the draw() method
So it just keeps repeating
Animate the writing, cycle colors eight times, clear the screen, repeat
dawn quiver
I have a lot of assignments to do, and its already past due date, but i can still submit it, but i want to continue my development on my project, idk what to do 😞
limber veldt
More better title screen!
See how easily I was able to implement what I just showed you a few minutes ago that I was just finishing at the time? Between then and now, I implemented that artwork into the game
I'll work later on animating the logo, it particle implodes onto the screen
Instead of just appearing
My game's gonna be so much like the original that people are going to accuse me of stealing the code from the author, lol
All those datas and we're well over 2k lines so far
Copy and paste the yellows and reds lists, assign them to variables, add one line to my draw() method to call the new draw_logo() method```py
def draw(self):
for coord in self.coord_list:
x = coord[0]
y = coord[1]
pygame.draw.line(screen, self.color, [self.x + x * 3 + 1, self.y + y * 3], [self.x + x * 3 + 1, self.y + y * 3 + 3], 3)
if not self.run_once:
pygame.time.delay(4)
pygame.display.flip()
self.run_once = True
self.draw_logo()
def draw_logo(self):
for coord in self.yellows:
x = coord[0]
y = coord[1]
pygame.draw.line(screen, YELLOW, [self.x + x * 3 + 1, self.y + 100 + y * 3], [self.x + x * 3 + 1, self.y + 100 + y * 3 + 3], 3)
for coord in self.reds:
x = coord[0]
y = coord[1]
pygame.draw.line(screen, RED, [self.x + x * 3 + 1, self.y + 100 + y * 3], [self.x + x * 3 + 1, self.y + 100 + y * 3 + 3], 3)```
The key to the whole workflow is the most simple class I've ever used, or one of them, ready?```py
class Spot:
def init(self, x, y):
self.x = x
self.y = y
self.color = WHITE
def draw(self):
pygame.draw.rect(screen, self.color, [self.x * wr, self.y * hr, wr, hr])```
Where wr and hr are the size of the cells I need
width and height
Then I can instantiate a 2d list of them like so....py cols = 30 rows = int(1200 / 8) grid = [[Spot(i, j) for j in range(cols)] for i in range(rows)]
And use them to do all kinds of things, art editor for one
And that's just for the editor code, int he game, I just have to draw the lines according to the coords the editor spits out to me
Reminds me of an old Blender trick I used to get all the vertex positions of a 3d model into a list for my rubik's cube code to use in drawing the same cube with a button click
Soooo tricky
I watched a tut on how to do it, the guy was a genius
Huge long lists of verts and faces, he had ways to automatically dump them to the actual script
Kinda shows the coords I get, they're in grid object coordinates
So I can draw on the canvas using the mouse buttons to put red or yellow cells then get a list of coords for each of them
And that's how I implemented that, lol...too late for the long story warning
I just used a slight variation of it for the Williams animation, drew red cells, got a list of all the coords, pasted them into the code so I could draw it at will, then adjusted the code so that every time I painted a new pixel onto that image, it added the coords to a list. I then had a sequential list of coords to animate the Williams thing
So not just an x,y or i,j list, a list with a specific order
I had to paint those cells manually and that was a bit of a grind but not bad, half hour or so and it was done
One by one, making sure not to mess up because I have no undo
But there isn't that many cells in the Williams animation
See, one just makes his own tools sometimes
