i have no idea how to do colisions

ü monster

Zacharý

QUOI-CK? How is this debugging?

Christopher

rubber ducks don't ask hard questions

how about it is not working, full game is broke fixing

how to collolide

1 hour later…

Christopher

01:19

gg this sucks

ETHproductions

01:47

what's going wrong

ASCII-only

@Christopher 1. define bounding box 2. check if any of the edges intersect

Christopher

02:01

i have collide

it work but not

basically if you go down the collision is wayyy to early

ETHproductions

sounds like you've got a math slightly wrong

ASCII-only

or several

ETHproductions

what line is the math for the collision on

ASCII-only

@Christopher is it because of the sprites pointing upwards

Christopher

@ASCII-only no by like half the screen

ASCII-only

02:03

@ETHproductions 82-103

@Christopher :/

Christopher

ok what should i do to fix?

ETHproductions

also how do I test game

Christopher

arrow keys

ASCII-only

@Christopher have you saved it

Christopher

now i have

ETHproductions

02:05

oh that's better

I don't see a sprite though

Just the whole level moving around

ASCII-only

@ETHproductions Yeah there's no sprite yet

ETHproductions

oh ok

I am a bad rubber duck

ASCII-only

@Christopher pls add wasd ty

Christopher

going to

have to remember the key codeds

Destructible Lemon

@Christopher bug report: can't move downward while touching left wall

or up

ETHproductions

02:07

@Christopher think they're 87, 65, 83, 68

Christopher

@DestructibleLemon yeah

ETHproductions

just the ASCII values of the uppercase letters

Christopher

i added WASD

ASCII-only

@Christopher wow KA processing has no keyname? how sad

ETHproductions

works perfectly, thanks

Christopher

02:09

@ASCII-only yep

ASCII-only

@Christopher ok so what's trans

Christopher

@ASCII-only short for translation

ETHproductions

I think I may know the problem

Christopher

aka the x/y cord of your person

@ETHproductions what is it

rubberducking is so easy when the rubber ducks talk and know programming :)

ETHproductions

height

isn't that just the height of the window

Christopher

02:11

yeah

same thing with width for th ex

ETHproductions

so you're only able to move, what, 400 px in each direction

actually no

Christopher

it just centers the collision and 300,300 (center)

ASCII-only

@Christopher ok so how are collide l/r and t/b different

Christopher

with l/r it is + or - width

t and b should be + or - but when i do b with the - everything breaks when you hit bot

ETHproductions

think round(x - 0.5) is floor(x), and round(x + 0.49) is ceil(x)

Destructible Lemon

02:16

I wonder how laggy it would be to draw a bunch of lines in pygame instead of using the preset ellipse drawer

Christopher

>_>

ETHproductions

@Chris You know what, I think the board is sideways

Destructible Lemon

it annoys me

Christopher

@ETHproductions welp

Destructible Lemon

the ellipse drawer is just like

Christopher

02:16

shit

Destructible Lemon

it's slightly off consistently

and there doesn't seem to be a way to fix it ever

Christopher

yeah

i gotta sleep

if you end up finding anything ping me. ty for help

ASCII-only

@DestructibleLemon screenshot pls

Destructible Lemon

like, not 100% crap all the time, but my fixing attempt so far haven't really fixed it

ASCII-only

pls?

Destructible Lemon

02:21

tbf i think it might be to do with the fact that it has x,y,height,width

ETHproductions

righted the board, now we have the same issue in the x-direction

Destructible Lemon

which means you get rounding errors from the rounding down twice for the rightmost portion or lowest portion

there probably is a way to fix it

also, it has stopped hanging off the side of the cylinder

ASCII-only

@DestructibleLemon doesn't explain why it stops halfway down

@ETHproductions link?

Destructible Lemon

@ASCII-only i was talking about my own unrelated game thing haha

ASCII-only

@DestructibleLemon then please correct to x1, y1, x2, y2

Destructible Lemon

02:23

yeah i guess

ETHproductions

@ASCII-only don't have one :/ just go into the drawMap() function and swap i and j

Destructible Lemon

I'm not sure whether the thing i'm making counts more as a game with easy level creation or a game engine

Christopher

@ETHproductions hit spin off button

ASCII-only

> Cannot read property '-7' of undefined

I think I might have found the source of the issue. maybe.

Destructible Lemon

ooh

who would be interested in playtesting my game thing when i finally get the graphics properly done and add the actual game part?

Christopher

02:32

Destructible Lemon

cool

ASCII-only

02:43

Fixed

@Christopher

but the side walls are sticky now for some reason

Christopher

@ASCII-only WHAT DID U DO

ASCII-only

@Christopher you did everything wrong..

Christopher

@ASCII-only no suprise

ASCII-only

i.e. collide

Christopher

can you share?

ASCII-only

02:50

hang on

trying to fix sticky walls

Destructible Lemon

i starred the link to be helpful

ASCII-only

@Christopher khanacademy.org/computer-programming/…

Christopher

what was wrong?

ASCII-only

all the collide functions?

also your map was the wrong way?

Destructible Lemon

the playfield looks different i was going to say

Christopher

02:55

hih

ASCII-only

see how there's no -

and look closely at which functions have x and y

Destructible Lemon

it's unfortunate that i can't imagine a way my game thing could be adapted to a koth

Christopher

ok so i got kicked from TNB while afk ????
