what does this mean?

chilly coral Mar 14, 2021, 2:42 PM

#

grand imp Mar 14, 2021, 2:42 PM

#

is this drawing it in the terminal or on some sort of 2d drawing surface?

chilly coral Mar 14, 2021, 2:42 PM

#

terminal drawing

grand imp Mar 14, 2021, 2:43 PM

#

hm

#

when you said "it doesn't work like that", do you mean that it doesn't draw pixel images in color?

chilly coral Mar 14, 2021, 2:43 PM

#

every line is a +1 on the y axis

chilly coral Mar 14, 2021, 2:43 PM

#

grand imp when you said "it doesn't work like that", do you mean that it doesn't draw pixe...

i thought you said i was giving it coordinates to drawing lines like a polygon

grand imp Mar 14, 2021, 2:43 PM

#

well

#

you said there were hitboxes that have arbitrary polygon boundaries, right?

#

and you want to use tiles as the basis of collision detection?

chilly coral Mar 14, 2021, 2:45 PM

#

me:
so i want 2 separate worlds
the rendering one
and the collision one

every object got its side on each world

sprites for the rendering one (visuals)
and a collision range for the other one

grand imp Mar 14, 2021, 2:45 PM

#

sprites for the visuals?

#

so this is a pixel based engine, in a sense

chilly coral Mar 14, 2021, 2:45 PM

#

ascii drawings

grand imp Mar 14, 2021, 2:45 PM

#

but it's drawing ASCII for the pixels

#

when you say collisions, are you imagining hitboxes like this but polygons?

chilly coral Mar 14, 2021, 2:47 PM

#

chilly coral Mar 14, 2021, 2:48 PM

#

grand imp when you say collisions, are you imagining hitboxes like this but polygons?

yes

grand imp Mar 14, 2021, 2:48 PM

#

so you want to use the overlap of the polygons to determine collision, not how the tiles are drawn?

chilly coral Mar 14, 2021, 2:48 PM

#

ye

grand imp Mar 14, 2021, 2:49 PM

#

ok, then you want a different algorithm than calculating each point along a line

chilly coral Mar 14, 2021, 2:49 PM

#

grand imp ok, then you want a different algorithm than calculating each point along a line

exactly

grand imp Mar 14, 2021, 2:49 PM

#

you can simplify the issue by not allowing concave polygons

#

but

#

there's no solution that's both flexible, simple, and efficient.

#

you have to choose two of the three

chilly coral Mar 14, 2021, 2:50 PM

#

so

#

how can i do it

#

I want only calculate the edges

grand imp Mar 14, 2021, 2:50 PM

#

what do you mean

chilly coral Mar 14, 2021, 2:51 PM

#

as you saw in my drawing, i only did points for the edges, not the inside

#

this is what i want

chilly coral Mar 14, 2021, 2:51 PM

#

grand imp so you want to use the overlap of the polygons to determine collision, not how t...

.

grand imp Mar 14, 2021, 2:51 PM

#

are you actually trying to ask about edges, or are you trying to find ways of answering the question of whether two shapes made of arbitrary polygons overlap?

chilly coral Mar 14, 2021, 2:51 PM

#

grand imp Mar 14, 2021, 2:51 PM

#

https://en.wikipedia.org/wiki/Weiler–Atherton_clipping_algorithm

Weiler%E2%80%93Atherton_clipping_algorithm

#

i think this is a solution people use

#

yeah i am too

chilly coral Mar 14, 2021, 2:52 PM

#

grand imp so you want to use the overlap of the polygons to determine collision, not how t...

.

grand imp Mar 14, 2021, 2:52 PM

#

i think it might be easier to break each shape into a bunch of triangles

chilly coral Mar 14, 2021, 2:52 PM

#

this

grand imp Mar 14, 2021, 2:52 PM

#

that'd be my approach

chilly coral Mar 14, 2021, 2:52 PM

#

i am confused

grand imp Mar 14, 2021, 2:52 PM

#

http://cgm.cs.mcgill.ca/~godfried/teaching/cg-projects/97/Ian/twoears.html

#

look at that page

#

the idea is that you can break any polygon into a bunch of triangles

chilly coral Mar 14, 2021, 2:53 PM

#

i dont want to do that

grand imp Mar 14, 2021, 2:53 PM

#

then choose a way of checking of the triangles overlap

#

why not?

chilly coral Mar 14, 2021, 2:54 PM

#

oh my god i lost it

grand imp Mar 14, 2021, 2:54 PM

#

if you only check if the edges intersect, then you might end up with a situation where a fast moving object clips through stuff

#

and ends up inside another poly

#

that's bad

chilly coral Mar 14, 2021, 2:55 PM

#

i have a solution

grand imp Mar 14, 2021, 2:56 PM

#

what is it?

chilly coral Mar 14, 2021, 2:58 PM

#

for every edge, get the edge that is past another one like:
edge1 ~~edge2~~ edge3
edge1 with edge3
and we do this so that we can make a sort of X
and this will only happen to 4 edges

grand imp Mar 14, 2021, 2:59 PM

#

im not sure i understand. are you treating the center as another point to make triangles with?

chilly coral Mar 14, 2021, 3:00 PM

#

grand imp Mar 14, 2021, 3:00 PM

#

well, I'm confused

#

you can try the solution you have and see if it works

chilly coral Mar 14, 2021, 3:01 PM

#

but idk how to get positions in between

#

when i will, i can make it then

grand imp Mar 14, 2021, 3:01 PM

#

but i think the algorithms i mentioned, and the general category of shape intersection algorithms, will be of help to you

dim loom Mar 14, 2021, 3:02 PM

#

hi

chilly coral Mar 14, 2021, 3:03 PM

#

so i said

#

we start from the first point, and get the other one
the other one will be: skip the second point and get the third
make a line between it
and now we start with the second point

#

but i just need

#

a sort of code

#

to get positions in between points

grand imp Mar 14, 2021, 3:07 PM

#

the positions between points
there are two things i'm confused about, but this one is the most important

#

if you are only looking at integer positions between points, then you are effectively drawing pixels

chilly coral Mar 14, 2021, 3:07 PM

#

i am drawing characters instead of pixels

grand imp Mar 14, 2021, 3:07 PM

#

no, you don't understand

#

if you generate a list of integer points between (1,1) and (1,5)

chilly coral Mar 14, 2021, 3:08 PM

#

exactly how the coordinates are
[x, y]

grand imp Mar 14, 2021, 3:10 PM

#

then trying to intersect the set of points from (1,1) to (1,5) and the set of points from (1,3) to (5,3) is the same as checking if two bitmaps with lines drawn on them overlap

#

and at the resolution you're working at, it's like checking if the sprites overlap

#

unless you have two different resolutions for sprite drawing and the collision bitmap masks

chilly coral Mar 14, 2021, 3:11 PM

#

the user will give the resolution he wants to...

grand imp Mar 14, 2021, 3:11 PM

#

do you have any experience with binary logical operators?

#

like ANDing two numbers, one that's 0b11100 with 0b10100

#

or whatever their hex / decimal version is

#

i don't mean image size btw, i mean relative resolutions of images

#

you know how the shadows in games on low are jagged and pixelated?

#

but then the texture of the object the shadow is projected onto is much higher resolution?

chilly coral Mar 14, 2021, 3:12 PM

#

grand imp you know how the shadows in games on low are jagged and pixelated?

yes...

grand imp Mar 14, 2021, 3:12 PM

#

that's the same sort of difference I mean

#

where unless the collision mask is generated with a higher resolution like the object receiving shadow relative to the shadow projection, there is no difference between checking for overlap between the sprites themselves

chilly coral Mar 14, 2021, 3:14 PM

#

so, you are telling me that getting points between start / end points is a pain?

#

i would just like to know how

#

i have a solution

#

for if the polygon is inside

grand imp Mar 14, 2021, 3:15 PM

#

I'm saying it makes no sense because you might end up with a situation like this, (0,0) in the upper left:

#

where red and green are the lines of two different polygons

#

as sets, green would be the set of integer points from (0,0) to (5,5)

#

red would be the set of integer points from (0,5) to (5,0)

chilly coral Mar 14, 2021, 3:17 PM

#

and i will get, that There is a collision

grand imp Mar 14, 2021, 3:17 PM

#

there isn't

chilly coral Mar 14, 2021, 3:18 PM

#

wait

#

what

#

they are intersecting....

grand imp Mar 14, 2021, 3:18 PM

#

oh i gave them six instead of 5 but

#

each square represents and integer point

#

there is no tile that is both red and green

#

so if you only look at the integer points in between the vertices of polygons, there will be cases where the lines of the polygons do not intersect when rendered to tiles

chilly coral Mar 14, 2021, 3:20 PM

#

uh

grand imp Mar 14, 2021, 3:21 PM

#

er wait

#

i did that wrong

#

i should have used python to generate those 😅

chilly coral Mar 14, 2021, 3:21 PM

#

anyways

#

how. are. you. generating. with. python
what code are u using

grand imp Mar 14, 2021, 3:22 PM

#

im not using python to do it

#

im drawing it in a js pixel editor

#

https://piskelapp.com

#

here's a very minimal example

#

green is the line from (0,1) to (1,0)

chilly coral Mar 14, 2021, 3:23 PM

#

k

grand imp Mar 14, 2021, 3:23 PM

#

red is the line from (0,0) to (1,1)

chilly coral Mar 14, 2021, 3:23 PM

#

AHH

#

yes

#

they are not touching

grand imp Mar 14, 2021, 3:24 PM

#

green: (0,1) (1,0)
red: (0,0), (1,1)

#

now do you see why only looking at the integer points between places will fail sometimes?

#

it will work a lot of the time, yes

#

but sometimes you'll have weird situations where shapes going fast enough will fly through one another and end up stuck inside each other like a bethesda game going wrong

chilly coral Mar 14, 2021, 3:25 PM

#

so

#

i have a solution

chilly coral Mar 14, 2021, 3:25 PM

#

dusk dome One message removed from a suspended account.

x)

grand imp Mar 14, 2021, 3:26 PM

#

the bigger point I'm making is that there are actually multiple kinds of collision detection used in games

chilly coral Mar 14, 2021, 3:26 PM

#

so i can simply check the corners like left by 1 pixel and right by one pixel

grand imp Mar 14, 2021, 3:26 PM

#

hmm

#

maybe

#

that will work for lower speed objects

#

but what if you have a very tiny object going fast at a larger line?

chilly coral Mar 14, 2021, 3:27 PM

#

oh

#

now a line

#

doing collisions is a pain

grand imp Mar 14, 2021, 3:27 PM

#

lmao, absolutely

#

imagine the little green rasterized diamond

chilly coral Mar 14, 2021, 3:28 PM

#

grand imp but what if you have a very tiny object going fast at a larger line?

it happens on all engines

grand imp Mar 14, 2021, 3:28 PM

#

is going really fast to the right

chilly coral Mar 14, 2021, 3:28 PM

#

i think

grand imp Mar 14, 2021, 3:28 PM

#

well

#

sort of

#

here's the thing

#

FPS engines actually sometimes have two kinds of collision detection

#

one for fast objects like bullets

#

and one for less fast objects

chilly coral Mar 14, 2021, 3:28 PM

#

a solution

#

i got one

grand imp Mar 14, 2021, 3:28 PM

#

the point I'm making is that a game engine on its own can't be that general

#

or it will suck at stuff

#

you have to choose what sorts of problems you're going to solve

#

and to do that, it's a good idea to have an idea of what kind of game you want to make in the first place

#

Unreal and Source were written and optimized with FPS games in mind

chilly coral Mar 14, 2021, 3:29 PM

#

grand imp Mar 14, 2021, 3:29 PM

#

you can do some other kinds of games with them

grand imp Mar 14, 2021, 3:30 PM

#

chilly coral

yep, you just described how bullet physics is done

#

only they use complicated math rather than integer spaces

chilly coral Mar 14, 2021, 3:30 PM

#

but

grand imp Mar 14, 2021, 3:30 PM

#

with Beth games, usually you aren't supposed to drink 5000 bottles of skooma at once

chilly coral Mar 14, 2021, 3:30 PM

#

that will work

grand imp Mar 14, 2021, 3:30 PM

#

it might!

chilly coral Mar 14, 2021, 3:30 PM

#

wait

grand imp Mar 14, 2021, 3:31 PM

#

but doing it only on integer spaces might also be kind of inefficient to do on CPU

#

if you're limited to only what's on the size of the terminal, it'll be fine

#

but if you have an off-screen world, it might start getting ugly

chilly coral Mar 14, 2021, 3:31 PM

#

grand imp if you're limited to only what's on the size of the terminal, it'll be fine

I am exactly limited to this:

grand imp Mar 14, 2021, 3:31 PM

#

you know how minecraft water updates really slowly?

chilly coral Mar 14, 2021, 3:31 PM

#

grand imp you know how minecraft water updates really slowly?

yes

grand imp Mar 14, 2021, 3:32 PM

#

yeah if you tried to make it go fast the simulation might have trouble working fast enough for the game to be playable

#

you could make a program that's a really good water simulation, but it would restrict the CPU and GPU time you have available to do stuff in the rest of the world

#

well

#

ok

#

you've made a choice

#

and a limitation

#

that's good

#

successful games development is really about choosing your limitations and assumptions

#

and then working with them

#

you played any source based games?

#

TF2, CS GO

just this

grand imp Mar 14, 2021, 3:37 PM

#

i told you, bresham will do that

chilly coral Mar 14, 2021, 3:37 PM

#

k

grand imp Mar 14, 2021, 3:37 PM

#

BUT

chilly coral Mar 14, 2021, 3:37 PM

#

grand imp BUT

yes?

grand imp Mar 14, 2021, 3:38 PM

#

the more complicated solutions people use for collision detection are used because they are reliable and efficient

#

now

#

what you can also do

#

is do a modified version of bresham where you draw the left and right bounds at each y position of a polygon

#

then fill each x position between the Y ones

#

that would let you use the set object in python

#

however, i think you could be more efficient than that

chilly coral Mar 14, 2021, 3:39 PM

#

so this?

grand imp Mar 14, 2021, 3:40 PM

#

chilly coral so this?

if this is what you're describing earlier, where you expand the number of points drawn by drawing all points within a radius of 1-3 (or really N) points from the line

#

that's pretty similar to drawing a line in photoshop with a pencil brush size of N rather than a size of 1

#

even if you're confused by all of this, what I want you to take away from this is that efficient collision detection in games is hard

#

and there's no perfect solution

#

you have to pick the weaknesses your solution has to suit the game you want to make

chilly coral Mar 14, 2021, 3:42 PM

#

and also consider the pain because i wont use any libs

grand imp Mar 14, 2021, 3:42 PM

#

you're not using libs because you want to learn, right?

chilly coral Mar 14, 2021, 3:42 PM

#

yes

grand imp Mar 14, 2021, 3:43 PM

#

ok, let me ask another question

#

are all parts of the environment able to move

#

or are there some shapes that will be unable to move

chilly coral Mar 14, 2021, 3:43 PM

#

everything can move

grand imp Mar 14, 2021, 3:44 PM

#

hm

#

so if you want to try doing your line solution

chilly coral Mar 14, 2021, 3:44 PM

#

not everything

#

can

grand imp Mar 14, 2021, 3:44 PM

#

https://www.redblobgames.com/grids/line-drawing.html this is a good interactive guide to bresham

chilly coral Mar 14, 2021, 3:44 PM

#

have collisions tho

#

if the user doesnt give collision points

grand imp Mar 14, 2021, 3:44 PM

#

or an algorithm like it

chilly coral Mar 14, 2021, 3:45 PM

#

then the object would'nt have collisions

grand imp Mar 14, 2021, 3:45 PM

#

btw, red blob games is good to check for other topics

#

the author makes really good articles

#

the example code is in JS but it's still pretty clear

chilly coral Mar 14, 2021, 3:46 PM

#

k! i will stick with bresham

#

Bresenham*

grand imp Mar 14, 2021, 3:46 PM

#

also lol they mention the diagonal non-intersection issue on that article

#

hmm

#

#

this might help your integer location collision mask approach work

#

ok, so if you want to try it

#

what you could do is one of the line drawing algorithms described, but instead of drawing, you take the current coordinate, and add it to a set in python

chilly coral Mar 14, 2021, 3:49 PM

#

hmm, i have another easier approach

grand imp Mar 14, 2021, 3:49 PM

#

shape_intersection_boundaries = set()
# you probably won't have a function like this, but i wrotte it this way for clarity
if point_is_on_line(x,y):
  shape_intersection_boundaries.add((x,y))

#

well, the easiest and most efficient approach is disallowing rotation and having only rectangular hitboxes

#

streetfighter 2 did that

chilly coral Mar 14, 2021, 3:50 PM

#

but my approach is

chilly coral Mar 14, 2021, 3:52 PM

#

chilly coral but my approach is

add +1 and check. if not, add -1 and check

grand imp Mar 14, 2021, 3:53 PM

#

not sure what you mean rn and i should probably get back to work on some stuff, but I hope discussing this at length helped at least a little

chilly coral Mar 14, 2021, 3:53 PM

#

#

so i check 1 more bit to the left and right

grand imp Mar 14, 2021, 3:56 PM

#

as in expand the area added to the mask by 1 more?

chilly coral Mar 14, 2021, 3:57 PM

ye and also substract by 1

grand imp Mar 14, 2021, 3:57 PM

#

i suspect you're still going to run into issues at some point

#

but if you set a hard upper limit on movement speed, you might be able to avoid the issue somewhat

You could probably do it with numpy and moderngl (for vfx).

restive lantern Mar 14, 2021, 10:25 PM

#

never heard of moderngl what is it?

normal silo Mar 14, 2021, 10:26 PM

#

like PyOpenGL, but nicer.

#

(specifically wraps opengl 3.3 core)

#

Another option is to write some cython code for the particles / collision.

If I wanted to draw something, let's say a bullet, in the main loop, before I use screen.fill(), how would I do this. (I need to draw something in an event.) This is in PyGame obviously

potent ice Mar 15, 2021, 4:09 PM

#

Make the event set some state instead

#

Check that state in the beginning of the draw loop

#

I would avoid drawing in events completely

finite badger Mar 15, 2021, 4:40 PM

potent ice I would avoid drawing in events completely

Alright

You might create the projectile, but it will still be drawn later

#

You might have a list of active projectiles for example

finite badger Mar 15, 2021, 5:42 PM

#

potent ice You might create the projectile, but it will still be drawn later

I have the rect ready for drawing

finite badger Mar 15, 2021, 5:43 PM

#

potent ice You might have a list of active projectiles for example

What do you mean by this?

potent ice Mar 15, 2021, 5:46 PM

#

There is only one rect?

#

I'm saying you can add a new rect to a list of active projectiles in the event (just an example)

#

The draw code will just that those rects

Are you able to delete rects?

you can remove from the list if needed

can someone show me how to do stuff in python by the user clicking a key

#

for example clearing a list by user clicking spacebar

abstract light Mar 15, 2021, 11:59 PM

#

ah

#

ok

#

@lament carbon you need to do a thread. Well Actaully that's what I did considering that was easy for me. But for you I would recomend using a while lloop

#

@lament carbon are you using pygame?

lament carbon Mar 16, 2021, 12:01 AM

#

oh no I know how to do it in pygame

#

I was asking if something similar can be applied

#

to more everyday programming tasks

such as clearing a list etc

#

could I import pygame and use it to clear stuff or anything of the sort by asking the user to click a button?

#

@abstract light

abstract light Mar 16, 2021, 12:03 AM

I think so yeah

#

so you know how to make a key right

#

you just need help on cleaning the screen

#

is that right?

#

@lament carbon

lament carbon Mar 16, 2021, 12:04 AM

more or less

#

I am thinking of K.LEFT

or whatever the syntax is

abstract light Mar 16, 2021, 12:05 AM

do I have to make a python game loop?]

well not really

#

are you asking the palyer to clear the screen?

#

if not and you just want them to screen

anytime

lament carbon Mar 16, 2021, 12:05 AM

its a normal program not a game

do you wanna see the whole thing?

it basically just takes user input as a number, finds whether it is an alternating number and then tells me whether it is or not. after that it appends it to a text file

abstract light Mar 16, 2021, 12:08 AM

#

ok so what I did was I made a input and told the player if you want to clear the screen press enter and if they did I would make screen clear using the os system

#

I also did a sleep system

lament carbon Mar 16, 2021, 12:08 AM

#

hmm im on windows sorry

abstract light Mar 16, 2021, 12:08 AM

#

yeah that is ok

lament carbon Mar 16, 2021, 12:08 AM

#

will it still work?

#

ok

abstract light Mar 16, 2021, 12:08 AM

#

Os system is a module

lament carbon Mar 16, 2021, 12:09 AM

#

oh import os?

abstract light Mar 16, 2021, 12:09 AM

#

not the operating system

#

yeah

lament carbon Mar 16, 2021, 12:09 AM

#

ok

abstract light Mar 16, 2021, 12:09 AM

#

and you name the function clear if you want

#

and after the input you would do clear()

#

so like this:

#

import os

#

def clear():
os.system("clear")

#

account = input("What do you want to do? ").strip()
if account == '1':
sleep(2)
clear()
block()

#

wait

#

I'll show you my whole code

lament carbon Mar 16, 2021, 12:10 AM

#

ok

#

how did you do that thing again?

#

I just feel like people should learn C

grim abyss Mar 16, 2021, 4:21 PM

c++ advocates would say that Python's type-system is used as a "crutch". Python's type system is Dynamic and C++ has a Static type system.

some times they won't let you go to specific places like in all games

#

you have to finish something

grim abyss Mar 16, 2021, 4:25 PM

#

well I don't actually own a VR headset but I'll keep my eyes peeled

#

i'm ready for starfield!

abstract light Mar 16, 2021, 4:26 PM

#

the game?

grim abyss Mar 16, 2021, 4:26 PM

#

yes

abstract light Mar 16, 2021, 4:26 PM

#

kind of excited here to

#

too*

grim abyss Mar 16, 2021, 4:26 PM

#

it's going to make up for the debacle that was Cyberpunk 2077!

#

and then some!!!!!

abstract light Mar 16, 2021, 4:27 PM

#

nice

#

what games do you currently play?

#

I'm not a super game person

#

so I won't know that much

grim abyss Mar 16, 2021, 4:28 PM

#

There's no way they just were purchased by MS and StarField is bad. MS must of seem something about that game that really grabbed their attention...

#

currently? Total War: Warhammer 2

#

No Man's Sky

abstract light Mar 16, 2021, 4:29 PM

#

what about uh valorant or Rocket league

grim abyss Mar 16, 2021, 4:29 PM

#

nah, not my cup of tea

true dagger Mar 16, 2021, 4:29 PM

#

grim abyss <@!476758641635229749> something like calling the method of a 'containsPoint' ch...

what is this?

abstract light Mar 16, 2021, 4:29 PM

#

it is what people call checking the coordiantes of the player

#

I think

#

I forgot terms

grim abyss Mar 16, 2021, 4:30 PM

#

@true dagger Well If you are using a 2D geometry library like "Planar". Then you can have line objects and they have a 'contains point' method...

abstract light Mar 16, 2021, 4:30 PM

#

yeah

#

well wait

#

no never mind

#

3D games will be hard to do

#

unlike the 2d games where you only need to axis

#

you will need 3 axis

#

a Z axis, a Y axis, and a X axis

grim abyss Mar 16, 2021, 4:32 PM

#

true dagger what is this?

You need good 'vector' support

#

vectors

abstract light Mar 16, 2021, 4:32 PM

#

X and Y you already know

#

Z is the top to bottom axis

#

if you want to set a hegiht limit

grim abyss Mar 16, 2021, 4:32 PM

#

yeah z is depth

#

top to bottom is Y

abstract light Mar 16, 2021, 4:34 PM

#

wait

#

no

#

it;s like

#

a normal coordinate sheet of paper

#

but when you make it 3d the perspective changes

grim abyss Mar 16, 2021, 4:35 PM

#

and there are multiple perspectives

#

world,screen,local etc

true dagger Mar 16, 2021, 5:04 PM

#

grim abyss You need good 'vector' support

wtym?

abstract light Mar 16, 2021, 5:14 PM

#

you mean what do you mean?

#

@true dagger

#

I think when he says vector support

#

he means the axis

#

I'm not sure

#

@grim abyss

grim abyss Mar 16, 2021, 5:16 PM

#

true dagger wtym?

https://mathinsight.org/vector_introduction

abstract light Mar 16, 2021, 5:17 PM

#

that might be alittle to much for him

grim abyss Mar 16, 2021, 5:17 PM

#

useful abstraction

abstract light Mar 16, 2021, 5:17 PM

#

he is only a beginner right?

grim abyss Mar 16, 2021, 5:17 PM

#

idk....lol

#

hmmm

abstract light Mar 16, 2021, 5:17 PM

#

actaully i think he can do it

#

can we see your code?

#

we will not steal don't worry

grim abyss Mar 16, 2021, 5:18 PM

#

@true dagger what's you Python skill level? How long have you been at it?

abstract light Mar 16, 2021, 5:18 PM

#

you mean turtle

grim abyss Mar 16, 2021, 5:18 PM

#

@true dagger you have a firm grasp of classes and OO yes?

abstract light Mar 16, 2021, 5:18 PM

#

classes are so annoying

grim abyss Mar 16, 2021, 5:19 PM

#

I think he nodded off

abstract light Mar 16, 2021, 5:19 PM

#

yeah

#

he did

#

I keep on forgeting to make variables global

grim abyss Mar 16, 2021, 5:19 PM

#

encapsulation is annoying? hmmmm...

#

polymorphism is annoying?

abstract light Mar 16, 2021, 5:19 PM

#

...

#

XD

grim abyss Mar 16, 2021, 5:19 PM

#

you must be an OG C programmer?

abstract light Mar 16, 2021, 5:19 PM

#

yeah right

grim abyss Mar 16, 2021, 5:19 PM

#

use Linux/GNU ?

abstract light Mar 16, 2021, 5:20 PM

#

who are you even asking

grim abyss Mar 16, 2021, 5:20 PM

#

hahahah

#

but why do you say classes are annoying?

abstract light Mar 16, 2021, 5:20 PM

#

beacuse there are some varaibel I would like to use

#

and then I have to make them global

#

and I forget to do that

finite jay Mar 16, 2021, 5:20 PM

#

yo gusy I need help on my game

abstract light Mar 16, 2021, 5:21 PM

#

yeah

#

which module?

#

Pygame

#

Pyglet

grim abyss Mar 16, 2021, 5:21 PM

#

@abstract light no you don't.

abstract light Mar 16, 2021, 5:21 PM

#

yeah you do

finite jay Mar 16, 2021, 5:21 PM

#

python

abstract light Mar 16, 2021, 5:21 PM

#

oh

#

so like terminal?

#

a terminal game?

finite jay Mar 16, 2021, 5:21 PM

#

I making like tile frenzy

#

for fun

abstract light Mar 16, 2021, 5:22 PM

#

on the terminal?

finite jay Mar 16, 2021, 5:22 PM

#

no

abstract light Mar 16, 2021, 5:22 PM

#

you just said python

#

python only has terminal unless you use a module

#

can we see your code?

#

@finite jay

grim abyss Mar 16, 2021, 5:23 PM

#

@abstract light I don't have a single global variable in that script I linked. If you need Globals your design is flawed....

#

classes provide the encapsulation

abstract light Mar 16, 2021, 5:23 PM

#

wait

grim abyss Mar 16, 2021, 5:23 PM

#

this is python not C

abstract light Mar 16, 2021, 5:24 PM

#

I think we are talking different stuff

grim abyss Mar 16, 2021, 5:24 PM

#

ohhh?

abstract light Mar 16, 2021, 5:24 PM

#

in pygame I make a player clas

#

and in that player class I make a varaible called coins

grim abyss Mar 16, 2021, 5:24 PM

#

yes

abstract light Mar 16, 2021, 5:24 PM

#

and I have the player's movements

#

and then I have the computer see if they have gotten a coin

#

and add it to it

#

it has worked

#

trust me

grim abyss Mar 16, 2021, 5:25 PM

#

yeah you lost me there

abstract light Mar 16, 2021, 5:25 PM

#

I was making a little rpg game

#

oh wait

#

I see the mistake

grim abyss Mar 16, 2021, 5:26 PM

#

show a code snippet

abstract light Mar 16, 2021, 5:26 PM

#

no I understand

#

it was my fault

grim abyss Mar 16, 2021, 5:26 PM

#

you're not explaining it well

#

I guess the other guy disappeared

abstract light Mar 16, 2021, 5:26 PM

#

i've been focused on def functions and using it in classes

#

yeah

#

I put the variables in a function called coins and use it class

#

I need to see if I have the code still

#

wait

grim abyss Mar 16, 2021, 5:27 PM

#

@abstract light self.coins is fine

#

that's your problem

abstract light Mar 16, 2021, 5:27 PM

#

I know how to do that

#

but I don't like to see so many selfs

#

wait

#

you want to make a project togethter?

#

just for fun

grim abyss Mar 16, 2021, 5:28 PM

#

sure. what type of project

abstract light Mar 16, 2021, 5:28 PM

#

anything

#

what do you want

grim abyss Mar 16, 2021, 5:28 PM

#

what's your experience level with python and 3rd party libs ?

abstract light Mar 16, 2021, 5:29 PM

#

eh

#

kind of

#

wait

#

I have to go

grim abyss Mar 16, 2021, 5:29 PM

grim abyss Mar 16, 2021, 8:01 PM

@abstract light so you're back eh? You never answered my question...

#

the only about you being familiar with 3rd party python libraries. your python skill level?

#

@abstract light Regardless, I'm ready if you are!

abstract light Mar 16, 2021, 8:03 PM

#

hmm

#

I'm familiar with 3D python libraries

#

and my python skill is ok I guess

In Pygame, does it hurt or help to do a simple rectangle collision before doing a pixel mask collision?

#

Odd question, just pinging any pygame experts

round obsidian Mar 17, 2021, 12:59 AM

#

@analog barn without knowing Pygame directly, I would say that is actually good to do - perform a coarse collision test first, then a fine test

#

the coarse test is faster

analog barn Mar 17, 2021, 1:01 AM

#

Alright, that makes sense to me. I am curious though... the way that Pygame detects mask collision is by simply comparing a 2d list of 0's and 1's, once the mask is created it should still be fast, just not as fast as rectangles.... I will time it later

abstract light Mar 17, 2021, 1:07 AM

#

Wait do you need help?

analog barn Mar 17, 2021, 1:07 AM

#

Not necessarily, just messing around learning masks

round obsidian Mar 17, 2021, 1:08 AM

#

collision tests are always best if you do coarse first, then fine

analog barn Mar 17, 2021, 1:36 AM

#

Errr we go! gotta love Pygame for how easy it is```py
# get collisions using rectangles
collisions = pg.sprite.groupcollide(self.ship.bullets, self.alien_fleet,
False, False)
for bullet, hit_list in collisions.items():
for alien in hit_list:
# use pixel mask collision
if pg.sprite.collide_mask(bullet, alien):
self.scoreboard.player_score += alien.point_value
alien.blow_up()

Should I write menu and game in same file or separate

last moon Mar 17, 2021, 5:32 AM

#

imo separate files allow you do separate your logic out but it's really a personal preference

#

coming back from java, it's hard to not make a new file for every class instinctively 😄

How does arcade/pyglet/moderngl send processes to the gpu?

potent ice Mar 17, 2021, 8:15 AM

#

last moon How does arcade/pyglet/moderngl send processes to the gpu?

"send processes" means what?

last moon Mar 17, 2021, 8:16 AM

#

Getting the gpu to run operations rather than sending them through the cpu?

potent ice Mar 17, 2021, 8:19 AM

#

It's fairly simple. Drawing/rendering operations requires primitives (points, lines, triangles) to reside in a buffer object in vram.

#

That buffer is processed by a shader and things appear on the screen

#

Maybe better to say a "gpu program".

#

The SpriteList in arcade is a good example. The user can change properties on each sprite such as position, rotation, texture

#

It keeps track of what data is changed internally and write that information to vram (a buffer)

#

Just think of the buffer as a numpy array or python array

#

It's expensive to keep data in system memory and vram in sync, but it's worth it when we batch draw everything.

#

The sprite list in arcade is drawn using a single render call

#

We maintain an [[x, y, rotation], [x, y, rotation], ...] list in system memory and write that to a buffer in vram when change is detected

#

(There are more properties of course)

Is that why quaternion math is used in 3d graphics?

potent ice Mar 17, 2021, 8:29 AM

#

I don't know how that is related

last moon Mar 17, 2021, 8:29 AM

#

Wouldn’t you store [x, y, z, rotation]?

potent ice Mar 17, 2021, 8:30 AM

#

oh. In my example the x, y, rotation are just 3 floats

#

It's a 2D example (Arcade)

last moon Mar 17, 2021, 8:31 AM

#

Ah nvm then I’m still trying to work 3D out conceptually

potent ice Mar 17, 2021, 8:32 AM

#

The reason quaternion are used is simply that they are simpler to work with because you won't have to worry about gimbal lock.

#

But they are converted to matrixes in the end

last moon Mar 17, 2021, 8:40 AM

#

So they’re used to make sure the 3 axis remain completely independent from each other?

potent ice Mar 17, 2021, 8:43 AM

#

They express rotations in a way you dont need to worry about it to put it simple

#

There are some great explanations of gibal lock using a paper plane if you seach

#

You can definitly avoid it using matrices. Still the quaternion way is nicer to work with ar times

#

I would not worry too much about it in the beginning.

#

Start with simple matrices. It's much simpler.

last moon Mar 17, 2021, 8:52 AM

#

I just can’t wrap my head around the whole 4d rotations in 3D space but I’ll dive into it more

potent ice Mar 17, 2021, 8:53 AM

#

I would put that on the shelf adding a mental note until you have the other topics sorted

#

It's much simpler to wrap your head around when you know 4 x 4 matrices well. Multiplication order etc.

#

For example the TRS rule (translation, rotation, scale)

#

v’ = T * R * S * v is important to understand

last moon Mar 17, 2021, 8:58 AM

#

That sounds familiar

potent ice Mar 17, 2021, 8:58 AM

#

v = 4 component vertex (x, y, z, w)

#

w = 1 unless you are doing something funky

last moon Mar 17, 2021, 9:00 AM

#

Isn’t v normalized too?

potent ice Mar 17, 2021, 9:01 AM

#

It's a vertex/position in space. so.. nope

last moon Mar 17, 2021, 9:02 AM

#

Maybe I’m thinking of rotation matrices

potent ice Mar 17, 2021, 9:03 AM

#

You'd rely on the matrix library you are using to keep things straight

#

Matrices / quats is a pretty huge topic. It's easy to get lost in the details. I would try to learn from a higher level first and actually use them in a simple project.

#

Unless you are extremely interested in math I would just jump into it and try some simple 3D with projection, and modelview matrix.

#

Play around with a simple solar system for example

#

Get a feel on how global / local rotations and translations works

last moon Mar 17, 2021, 9:14 AM

#

Jokes on you I’m just here for the math idc about the graphics

#

I’m sure higher level examples would help but I’m honestly a lot more interested in the low level concepts

#

#

potent ice Mar 17, 2021, 9:25 AM

#

It's template based so it can be a bit confusing. Still a great reference when you find the implementation (ignore header files that are just template stuff)

last moon Mar 17, 2021, 9:26 AM

#

potent ice That buffer is processed by a shader and things appear on the screen

So does this shader differ from shaders written in the program or do those shader overwrite it?

potent ice Mar 17, 2021, 9:27 AM

#

A common "program" has a vertex shader and fragment shader attached

#

The vertex shader just transforms each vertex. That's it

#

It takes in a vertex and all its additional info such as color (or whatnot) and transforms it using the supplied projection/modelview matrix

#

Based on what primitive mode you are rendering with (points, lines, tringles) all the transformed vertices will go to the primitive assembly stage.. clipping etc.

#

Then the fragment shader will run for each pixel on the screen that are part of the primitive.

#

You get all the information about the primitive as input in the fragment shader. Primitives are always rendered in the order they arrived

Hi my daughter has decided to take computer science as a school option.
I am trying to find ideas for simple but fun ideas that would engage her.
I pitched typical tic tac toe but these are met with just flat 'what ever' 'meh' all she does most days is trawl through reels. I thought about pulling in reels and say YouTube one into one but it seems Facebook api doesn't allow anything more than allowinf you to pull your own info.
I thought maybe we could make a meme caption game but with this idea it would require multiple players and I feel this might be a bit to much. Any ideas how this could be kept simple or any other ideas that might get a 13year old enthusiastic?
Many thanks

hmm. Very individual what is hit and miss. The most popular project I worked on with my 14 year old nephew was a game were the enemies was his fathers heads trying to reach the middle of the screen were the internet router was located. You had to "pick them up" with the mouse. If one enemy reached the router it was game over. "No more internet" 😄

#

My brother almost died of laughter when we showed the game. It was not my idea!
