what the frick

for i in layer_order:
        draw_layer(screen, layers[i], layers[i+1] if i ==len(layers) else None, cylinders_layers[i], zoom_multiplier)

ASCII-only

@DestructibleLemon then how is it a bug...

Destructible Lemon

doesn't give out of index error

for i in layer_order:
    draw_layer(screen, layers[i], layers[i+1] if i >= len(layers) else None, cylinders_layers[i], zoom_multiplier)

also no out of index

ASCII-only

O_o

Destructible Lemon

 for i in layer_order:
        draw_layer(screen, layers[i], layers[i+1] if i >= len(layers)-1 else None, cylinders_layers[i], zoom_multiplier)

out of index error

@ASCII-only no weird part yet, now i have posted it

ASCII-only

@DestructibleLemon ok. not print layers[i], layers[i+1], cylinders_layers[i] on the line before

Destructible Lemon

02:49

it's the layers[i+1] if i >= len(layers)-1 else None

by the way

i just...

how is giving it None more often going to make it error

what

it doesn't even affect the part that's being indexed

ASCII-only

@DestructibleLemon put parens around and try again

Destructible Lemon

wait, somehow it is being indexed in the len layers

what the actual frick

(len(layers)-1) else None
IndexError: list index out of range

i'm sorry what

where's the fucking list index there

ASCII-only

i+1?

Destructible Lemon

how is i+1 a list index?

ASCII-only

in layers[i+1]?

Destructible Lemon

02:52

it doesn't error if i remove the -1 though

ASCII-only

because i is never >= len(layers)...

Destructible Lemon

and its not an error there

oh wait

i figured it out

ASCII-only

and layers[i+1] doesn't exist when i == len(layers) - 1...

Destructible Lemon

however

what the frick still

ASCII-only

...

Destructible Lemon

02:53

the error messages were anti-helpful

it's because the inequality is reversed

ASCII-only

~~quack~~ did you actually figure it out

@DestructibleLemon exactly...

Python doesn't know you want it the other way

Destructible Lemon

but why the frick was the error pointing to a line not containing indexing

ASCII-only

if you think it's not hard then please describe the situations during which it should warn about an incorrect inequality

Destructible Lemon

it's not the inequality

the inequality was the reason it was happening

but it should point to where the indexing is happening

not some near place

ASCII-only

Oh, that's what you mean

Destructible Lemon

02:55

anyway, it seems to be almost working

ASCII-only

@DestructibleLemon the first line is the entire line right?

then submit to Python as bug report

Destructible Lemon

I don't know

still have minor annoying bugs

but not severe ones

something that meets at a face should meet at a face dangit

at the moment there are little visible bits of the top of cylinders which should not have visible tops

ASCII-only

@DestructibleLemon pls screenshot

Destructible Lemon

sort of fixed

but pygame is being annoying about the size of things

for some reason it thinks things which have the same coordinates shouldn't match up

drives me insane

I'm switching to pyglet soon

Whoops, I was affected by TNB link effect / Anyway I don't find the method very effective.

8 hours later…

Christopher

22:05

Anyone wanna duck?

ETHproductions

hello there

Christopher

hey

So i am trying to figure out how I want to program this game

khanacademy.org/computer-programming/fbla-sandbox-game/…

i don't know if i should focus on function based programming

or just OOP

or a mix

hmmm

ETHproductions

I like OOP myself, though function-based seems to work slightly better on KA in general IIRC

Whatever you feel best with

Christopher

yeah

i think OOP for the player

rest be function

brb getting blanket

@ETHproductions with prefix notation does prefix get evaluted before checking math and stuff

ASCII-only

OOP

pls

@Christopher checking math?

Christopher

22:16

@ASCII-only KA makes OOP hard :P

ASCII-only

@Christopher why

Christopher

@ASCII-only yeah my dad gave answer

:43084258¯\_(ツ)_/¯

ASCII-only

@Christopher what do you mean by checking math though

Christopher

@ASCII-only making sure for loop was gud

ASCII-only

@Christopher ... so it makes OOP hard but you don't know why?

Christopher

22:17

@ASCII-only yep

it just is

you have to deal with funky debugger making it a pain

ASCII-only

no?

Christopher

i had working valid code that the debugger forced me into using a try catch with no handle

ASCII-only

example pls

Christopher

busy

ETHproductions

makes me wanna clone their interpreter and remove the debugger

Christopher

22:20

you can disable it in editor with a few tricks

level drawing is up and running

/afk for 40 min

ETHproductions

wow it's gotten way worse since I was last on

or maybe it's just me?

1 hour later…

Christopher

23:31

@ETHproductions both

Zacharý

Quack

Destructible Lemon

hello

Christopher

hey

khanacademy.org/computer-programming/fbla-sandbox-game/…

this has to be ready full game in under 3 days

I have a choice

I am thinking about making the main person color blind and deaf

so A. No colors to do, B. no audio. C. compelling story of overcoming hardship

good idea?

Destructible Lemon

you still have to do greys

Christopher

yeah grays are ez

gray scale is super simple

Destructible Lemon

23:35

if you like that

Christopher

yeah i think i can tell a nice story and it will cut time

hmmm

hmmmmmmmmmmm

@DestructibleLemon so this follows the life of a typical FBLA member (rules said so) so you have to have fundraising stuff and whatever to do. Trying to figure out what direction the story should take

dark/gloomy to happy?

overall happy?

Destructible Lemon

what is fbla

Christopher

future business leaders of america

national thing

Destructible Lemon

weird

Christopher

nah cool

anyways how should I put the mood of the gam

Destructible Lemon

23:39

i'm not so good at that sort of thing

Christopher

same

asking TNB

ASCII-only

@Christopher no thx

Christopher

allows for a more compelling story

ASCII-only

if it's written badly then people will think it was just an excuse (which is was)

Christopher

I can write it :P

also i can't do audio with this PJS fork

I am going to national championship if it is good or not

iirc 1 other group in the state does this one

(game creation)

ASCII-only

23:48

... wow that's not many at all

Christopher

yah

ASCII-only

also 1/10 so much progress

Christopher

i had to do work for an hour

just got back

oop sucks
