How to fix my code? | Together C & C++ | Page 2

royal nimbus Jun 25, 2024, 7:07 AM

#

yeah

compact coral Jun 25, 2024, 7:07 AM

#

okay so that just moves the problem

royal nimbus Jun 25, 2024, 7:07 AM

#

:/

compact coral Jun 25, 2024, 7:07 AM

#

that's still the same thing

#

local memory after return

#

you want the fun answer or the easy answer 😛

royal nimbus Jun 25, 2024, 7:08 AM

#

now the unique ptr error got resolved

#

just fix the return thing

#

both?

#

like

#

i want to hear about both

compact coral Jun 25, 2024, 7:08 AM

#

the fun answer is chunks should be a unique_ptr not a raw pointer 😛

#

the easy answer is to throw in the towel and just use shared_ptr

#

probably instead of unique

#

(and change chunks back to how it was)

#

FWIW I think the code you had was correct on other compilers

#

it seems a weird MSVC bug is stopping it working properly

royal nimbus Jun 25, 2024, 7:14 AM

#

#

compact coral Jun 25, 2024, 7:15 AM

#

yea std::pair doesn't have move

#

you may have to use the [cid] = value version

royal nimbus Jun 25, 2024, 7:16 AM

#

i cannot comprehend the error message lmao

#

okay

royal nimbus Jun 25, 2024, 7:16 AM

#

compact coral you may have to use the `[cid] = value` version

that doesn't cause error?

compact coral Jun 25, 2024, 7:16 AM

#

I have no idea at this point

#

I think MSVC compiler is just wrong here

royal nimbus Jun 25, 2024, 7:17 AM

#

compact coral Jun 25, 2024, 7:19 AM

#

I'm an idiot

royal nimbus Jun 25, 2024, 7:19 AM

#

compact coral Jun 25, 2024, 7:19 AM

#

display world

royal nimbus Jun 25, 2024, 7:19 AM

#

youre not 🙂

compact coral Jun 25, 2024, 7:19 AM

#

auto& sylva = planets[playerPlanet];

#

change to this

#

no unique ptr needed on chunks

royal nimbus Jun 25, 2024, 7:19 AM

#

oops

compact coral Jun 25, 2024, 7:19 AM

#

(although in it, yes)

#

insert should be fine

#

you can't copy planets

#

or you will get that error

#

but yea, unwind to when that error was causing problems

#

this is what I had building

#

vector<vector<vector<unique_ptr<Item> > > > createChunk(string planet, int x, int y) {
    //TODO:Actually generating terrain
    vector<vector<vector<unique_ptr<Item> > > > a;
    a.resize(256);
    for (int i = 0; i < 255; i++) {
        a[i].resize(16);
        for (int j = 0; j < 16; j++) {
            a[i][j].resize(16);
        }
    }
    return a;
}
struct Planet {
    string name;
    unordered_map<string, vector<vector<vector<unique_ptr<Item> > > > > chunks;
    vector<vector<vector<unique_ptr<Item> > > >& getChunk(int x, int y) {
        string cid = to_string(x) + "," + to_string(y);
        auto a = chunks.find(cid);
        if (a == chunks.end()) {
            chunks.insert({ cid, createChunk(name, x, y)});
            return chunks[cid];
        }
        else {
            return a->second;
        }
    }

#

probably going to call it a night soon

#

but am curious to see what you come up with!

royal nimbus Jun 25, 2024, 7:22 AM

#

bye

compact coral Jun 25, 2024, 7:22 AM

#

(do let me know if that works :P)

royal nimbus Jun 25, 2024, 7:23 AM

#

you need a move obviously

#

but it works

compact coral Jun 25, 2024, 7:24 AM

#

freaking where

#

lol

royal nimbus Jun 25, 2024, 7:26 AM

#

royal nimbus Jun 25, 2024, 7:26 AM

#

compact coral freaking where

in the insert

compact coral Jun 25, 2024, 7:27 AM

#

whats the create chunk signature?

royal nimbus Jun 25, 2024, 7:27 AM

#

compact coral Jun 25, 2024, 7:27 AM

#

that ampersand is a problem

#

remove it and the move

#

you can't make references to local variables and return them

#

stop it

pale estuary Jun 25, 2024, 7:29 AM

You two will become besties soon yamikek

compact coral Jun 25, 2024, 7:29 AM

#

no

#

I am going to bed 😛

royal nimbus Jun 25, 2024, 7:29 AM

#

no errors now

compact coral Jun 25, 2024, 7:29 AM

#

royal nimbus Jun 25, 2024, 7:29 AM

#

ah right that debug spanner

compact coral Jun 25, 2024, 7:29 AM

#

those numbers are indeed the same

royal nimbus Jun 25, 2024, 7:29 AM

#

i'll stop throwing spanners into the program ❤️

compact coral Jun 25, 2024, 7:29 AM

#

only took like 6 hours

royal nimbus Jun 25, 2024, 7:29 AM

#

yeah lmao

#

atleast i learned about unique pointers

pale estuary Jun 25, 2024, 7:30 AM

#

compact coral only took like 6 hours

Tbh anything 3d related usually takes 6 months and not 6 hours so 💀

compact coral Jun 25, 2024, 7:30 AM

#

it's on a console so it's not that 3d yet

pale estuary Jun 25, 2024, 7:31 AM

#

Oh

#

The intrusive thoughts are telling me to make a physics engine 😭

royal nimbus Jun 25, 2024, 7:31 AM

#

pale estuary Jun 25, 2024, 7:31 AM

#

Maybe I'd actually learn physics once instead of using the formula book thingy

pale estuary Jun 25, 2024, 7:32 AM

#

royal nimbus

Segfault :3

royal nimbus Jun 25, 2024, 7:32 AM

#

ah right

pale estuary Jun 25, 2024, 7:32 AM

#

flooshed

royal nimbus Jun 25, 2024, 7:32 AM

#

i changed some stuff

#

it was "air"

#

now its just null

#

have to make that change lmao

#

how do i stop the program from randomly stopping

compact coral Jun 25, 2024, 7:36 AM

#

stop having exceptions?

#

that's the debugger crashing on an exception usually

#

or it's hitting a break point

royal nimbus Jun 25, 2024, 7:37 AM

#

oh

#

click continue

#

idk why but it stops on int main

compact coral Jun 25, 2024, 7:37 AM

#

did you put a break point there?

#

the little red ball to the left of it?

royal nimbus Jun 25, 2024, 7:38 AM

#

no

pale estuary Jun 25, 2024, 7:39 AM

#

What does it say when it stops?

royal nimbus Jun 25, 2024, 7:39 AM

#

📎 ConsoleApplication1.cpp

#

nothing

pale estuary Jun 25, 2024, 7:39 AM

#

Well there should be a breakpoint then?

royal nimbus Jun 25, 2024, 7:39 AM

#

but now i found out that if i select a nullptr in the cursorAt=0 then it will break

pale estuary Jun 25, 2024, 7:39 AM

#

Hmm maybe some conditional breakpoint that you accidentally enabled

royal nimbus Jun 25, 2024, 7:40 AM

#

btw i clicked f11 for build

pale estuary Jun 25, 2024, 7:41 AM

#

thonk

#

Idk build us ctrl+b by default on VS

#

And running with a debugger attached is f5

royal nimbus Jun 25, 2024, 7:42 AM

#

oh

#

ctrl+b?

pale estuary Jun 25, 2024, 7:42 AM

#

iirc that's build

#

Yes

#

(build but does not run it)

royal nimbus Jun 25, 2024, 7:42 AM

#

very fixed

#

📎 ConsoleApplication1.cpp

pale estuary Jun 25, 2024, 7:42 AM

#

When you press run the ide builds for you and then runs the exe

royal nimbus Jun 25, 2024, 7:43 AM

#

now i'll just have to do the f key handling

#

and my "job" today is done!

compact coral Jun 25, 2024, 7:58 AM

#

well good luck! actually going to bed now lol

royal nimbus Jun 25, 2024, 7:58 AM

#

byw

#

bye

royal nimbus Jun 25, 2024, 9:22 AM

#

oof solved a hideous bug

#

xxx.content==nullptr is a valid statement

#

but you really intended to write *xxx.content==nullptr

#

atleast the error rate is less than that of javascript(a weakly typed language or something)

royal nimbus Jun 25, 2024, 9:59 AM

#

phew

#

finally

#

done!

royal nimbus Jun 26, 2024, 1:54 AM

compact coral I do not have windows, lol

throw away the windows.h related code and try to make your executable run on a ansi compatable application

compact coral Jun 26, 2024, 1:56 AM

#

this kinda sounds like work, what are you actually trying to fix at this point? or are you just wanting a code review?

royal nimbus Jun 26, 2024, 1:56 AM

#

code review

#

i did the update thing(confusing because its both the minecraft update and the minecraft schedule tick)

#

now there are two new items:a pacemaker and a siren

#

pacemakers schedule themselves as update and update their surroundings

#

sirens change color when updated

compact coral Jun 26, 2024, 2:06 AM

#

#

is it supposed to look like this?

#

well it seems to work anyway

#

📎 test.cpp

#

here is the version that worked for me, if you want some sort of cross platform support

#

I only changed the init function and above besides replacing _getch() with the helper I defined

#

which brings me to my first bit of code review advice, use a library for console IO

#

a TUI library

#

there are a bunch of choices

#

it's very impressive you figured this all out yourself, but use a library for the love of all that is holy

#

Curses, FTXUI, Notcurses, etc.

royal nimbus Jun 26, 2024, 2:11 AM

#

compact coral

yeah!

compact coral Jun 26, 2024, 2:11 AM

#

also we have a #1078717238678409369 forum here for code review 😛

royal nimbus Jun 26, 2024, 2:11 AM

#

curses sounds familliar

royal nimbus Jun 26, 2024, 2:12 AM

#

compact coral also we have a <#1078717238678409369> forum here for code review 😛

yeah but i forgot to post it there after posting it here

royal nimbus Jun 26, 2024, 2:12 AM

#

compact coral

can you press space a few times and verify there is a siren next to the pacemaker?

#

I can't see it clearly

#

if you press space the siren will change color

#

so i can see it(you can also see it)

royal nimbus Jun 26, 2024, 2:13 AM

#

compact coral it's very impressive you figured this all out yourself, but use a library for th...

well i asked "the intellegence dampening core LLM" (read:chatgpt)lmao

#

oh another he didnt come and tell me i should use llvm lol

compact coral Jun 26, 2024, 2:14 AM

#

only happens once a day

#

I think across all the threads in a channel

royal nimbus Jun 26, 2024, 2:14 AM

#

ah ok

#

oh

compact coral Jun 26, 2024, 2:14 AM

#

royal nimbus Jun 26, 2024, 2:15 AM

#

yeah i was wondering it was already 1 day

royal nimbus Jun 26, 2024, 2:15 AM

#

compact coral

yes that is good hooray!

#

if you move the pacemaker it should not break and the siren if nearby should still function

compact coral Jun 26, 2024, 2:16 AM

#

I don't know what these things do 😛

#

my first part of feedback would be, add more explorable UI

#

#

this is dwarf fortress for example

#

note it has descriptions and help ui for cammnds

royal nimbus Jun 26, 2024, 2:17 AM

#

ooh nice okay

#

yeah maybe

#

i'll check curses first

compact coral Jun 26, 2024, 2:20 AM

#

it also takes up this huge amount of my termianl for I think no reason

#

#

which is annoying 😛

royal nimbus Jun 26, 2024, 2:20 AM

#

yeah,sorta...

#

I hardcoded it to be 100x50 because i found out that it worked on my powershell and my screen res

#

with no consideration of cross platform stuff

#

i need to figure some stuff...

#

(not gonna change the 100x50,maybe i will adjust font size or smth)

compact coral Jun 26, 2024, 2:22 AM

#

you can't adjust the font, that's up to the user's terminal 😛

royal nimbus Jun 26, 2024, 2:22 AM

#

font size

#

not font

#

oops

compact coral Jun 26, 2024, 2:22 AM

#

yes, up to users terminal

royal nimbus Jun 26, 2024, 2:22 AM

#

oh

compact coral Jun 26, 2024, 2:22 AM

#

yea you operating in the very ancient technologies zone

royal nimbus Jun 26, 2024, 2:22 AM

#

yeah agree

compact coral Jun 26, 2024, 2:22 AM

#

there are commands to read terminal size last I remember

#

it's okay I found where I can change the W and H

royal nimbus Jun 26, 2024, 2:23 AM

#

there are commands to read and write terminal size

royal nimbus Jun 26, 2024, 2:23 AM

#

compact coral it's okay I found where I can change the W and H

be warned it might not work fully
also if the numbers are too low you will get a vector index out of range run time error

compact coral Jun 26, 2024, 2:24 AM

#

#define W 50
#define H 30

works much better for me 😛

royal nimbus Jun 26, 2024, 2:24 AM

#

😛

#

now you get a rte if an item has more than 11 slots or has a name longer than 50 chars

compact coral Jun 26, 2024, 2:25 AM

#

compact coral

if you want me to be able to keep easily running it you should make sure to incorporate these changes so next time you send it I can compile it easily

compact coral Jun 26, 2024, 2:25 AM

#

royal nimbus now you get a rte if an item has more than 11 slots or has a name longer than 50...

you should fix that

#

there is a lot of code quality concerns here you should work on really

#

what is your goal with this

royal nimbus Jun 26, 2024, 2:26 AM

#

(oh wait the player has more than 11 slots,trigger the bug by pressing o when selected the blue at sign in the middle of the 0 field!)

royal nimbus Jun 26, 2024, 2:26 AM

#

compact coral there is a lot of code quality concerns here you should work on really

yeah right

royal nimbus Jun 26, 2024, 2:26 AM

#

compact coral you should fix that

im working on curses stuff

compact coral Jun 26, 2024, 2:26 AM

#

you should also consider putting it on github

#

so you can track versions and send people links to it

#

instead of copy pasting the file every time

royal nimbus Jun 26, 2024, 2:27 AM

#

yeah i've never been used to git stuff

compact coral Jun 26, 2024, 2:27 AM

#

it's pretty straightforward

compact coral Jun 26, 2024, 2:27 AM

#

compact coral what is your goal with this

still wondering about this

royal nimbus Jun 26, 2024, 2:27 AM

#

git push
git commit
git outta here
right?

#

lol

royal nimbus Jun 26, 2024, 2:27 AM

compact coral still wondering about this

what this?

compact coral Jun 26, 2024, 2:27 AM

heh wrong order

compact coral Jun 26, 2024, 2:28 AM

#

royal nimbus what this?

what is your goal with this project?

royal nimbus Jun 26, 2024, 2:28 AM

making a game

compact coral Jun 26, 2024, 2:28 AM

you commit to make a save point, you push to sync that save point with the server

royal nimbus Jun 26, 2024, 2:28 AM

#

those are three different operations

royal nimbus Jun 26, 2024, 2:29 AM

#

compact coral okay, for how long? how far do you plan on going with this?

for...some time
im programming like a feature for like an hour every day

compact coral Jun 26, 2024, 2:29 AM

#

yea, I would say get it in git

#

that's definitly step 1

#

then learn how to add libraries, specifically curses, that's step 2

#

then keep working on it and refactor as you go

#

the git repository supports step 2, because it will be easier for other people compile your thing if you put the libraries in git

#

once you add curses it will be harder for you to drop me a file and have me compile it, cause I need the library too

royal nimbus Jun 26, 2024, 2:31 AM

#

compact coral Jun 26, 2024, 2:32 AM

#

you'll need to download and include the library

#

probably compile it too

royal nimbus Jun 26, 2024, 2:34 AM

cant get ncurses.h in my ncurses installment?

#

i downloaded the newest version from gnu

royal nimbus i downloaded the newest version from gnu

you aren't using mingw anymore

royal nimbus Jun 26, 2024, 2:36 AM

#

omfg its so complicated

compact coral Jun 26, 2024, 2:36 AM

#

you need it in visual studio

compact coral Jun 26, 2024, 2:36 AM

#

royal nimbus omfg its so complicated

yes lol

royal nimbus Jun 26, 2024, 2:36 AM

#

oh

compact coral Jun 26, 2024, 2:36 AM

#

royal nimbus what's make?

you probably want cmake

royal nimbus Jun 26, 2024, 2:36 AM

#

i think i saw cmake yesterday

compact coral Jun 26, 2024, 2:37 AM

#

royal nimbus i downloaded the newest version from gnu

doing this would be correct if you were on linux lol

#

so that was a smart idea :p

#

but you probably want "insall ncurses for visual studio"

they don't change that much between versions? depends on how the instructions work

royal nimbus Jun 26, 2024, 2:40 AM

#

found this

#

searched vcpkg

#

it was existing

#

compact coral Jun 26, 2024, 2:41 AM

#

vcpkg is probably the right way to install libraries, yes

royal nimbus Jun 26, 2024, 2:43 AM

#

after putting ncurses-6.5 in my linker

#

it doesn't work

#

compact coral Jun 26, 2024, 2:43 AM

#

royal nimbus it doesn't work

be more specific

#

and also look upt he documentationf or how you are supposed to install this

royal nimbus Jun 26, 2024, 2:44 AM

did not do anything

#

documentation is probably without vs

royal nimbus Jun 26, 2024, 2:45 AM

compact coral Jun 26, 2024, 2:45 AM

probably need to go ask someone who is vcpkg pilled for help?

oh wait

my program works perfectly without windows.h

#

only exception is that flashing cursor at the origin

compact coral Jun 26, 2024, 2:49 AM

#

I mean the point of curses is to make it easier to do terminal programming

#

not just to fix the cross platform issues

royal nimbus Jun 26, 2024, 2:49 AM

#

like

#

yes and this is called "terminal user interface" or TUI

royal nimbus Jun 26, 2024, 2:50 AM

#

ahh okay

#

i should still installl curses and learn vcpkg tho

compact coral Jun 26, 2024, 2:50 AM

#

yes

#

and git

royal nimbus Jun 26, 2024, 2:50 AM

#

yeah that link doesn't work

#

its the same one i talked about assuming no vcpkg

#

i mean assuming no vs

#

in retrospect i dunno how this code would help in forcing ansi escape

#

its not using the dwMode for anything lmao

royal nimbus Jun 26, 2024, 3:22 AM

compact coral Jun 26, 2024, 3:23 AM

you may have to use a different TUI library then

royal nimbus Jun 26, 2024, 4:20 AM

#

royal nimbus Jun 26, 2024, 4:55 AM

#

#

@compact coral ?

compact coral Jun 26, 2024, 6:07 AM

#

royal nimbus why am i x64 windows though

cause you are building on windows and have like a 64 bit processor

royal nimbus Jun 26, 2024, 6:07 AM

#

isnt that x86?

compact coral Jun 26, 2024, 6:07 AM

#

x86 refers to the 32 bit processor, first started with the 8086, sometimes called 386 (hence the X)

royal nimbus Jun 26, 2024, 6:08 AM

#

ahh okay

compact coral Jun 26, 2024, 6:08 AM

#

x86-64 is the long name for what you are likely on

#

x86 with 64 bit extensions

royal nimbus Jun 26, 2024, 6:08 AM

#

ahh okay

#

nice

compact coral Jun 26, 2024, 6:08 AM

hmmm

#

let me see

compact coral Jun 26, 2024, 6:11 AM

#

I am going to bed soon btw

royal nimbus Jun 26, 2024, 6:11 AM

#

okay

#

probably not this one...

#

i just need a way to hide the cursor

#

and force ansi escape mode

compact coral Jun 26, 2024, 6:15 AM

#

you can do it the way you had it before I suppose, the platform specific one

#

just use the ifdefs to support multiple platforms

royal nimbus Jun 26, 2024, 6:15 AM

#

what ifdefs?

compact coral Jun 26, 2024, 6:16 AM

#

compact coral

compare what I compiled to what you have

📎 ConsoleApplication1.cpp

compact coral Jun 26, 2024, 6:34 AM

#

lol I dunno what windows has

#

do

#ifndef _WIN32
char _getch() {
    return getchar();
}
#endif

instead then

royal nimbus Jun 26, 2024, 6:35 AM

#

yeah conio.h has its getch

#

either use windows.h and define stuff or not and ifndef

compact coral Jun 26, 2024, 6:35 AM

#

ifndef is "if not defined

royal nimbus Jun 26, 2024, 6:35 AM

#

yeah ik

#

also wouldn't your polyfill make it that you need to press enter every time?

compact coral Jun 26, 2024, 6:36 AM

#

nope, getchar works the way getch does

#

It seems to be working fine without hitting enter as well too

royal nimbus Jun 26, 2024, 6:37 AM

#

ah ok

compact coral Jun 26, 2024, 6:37 AM

#

gotta be honest it's been a very long time... like 15 years since I screwed around with this

royal nimbus Jun 26, 2024, 6:37 AM

#

on my setup getchar did not work without enter

#

so nice polyfill

compact coral Jun 26, 2024, 6:37 AM

#

it may have to do with the other terminal settings I added

royal nimbus Jun 26, 2024, 6:37 AM

#

yeah

📎 ConsoleApplication1.cpp

#

I did not tamper with display code since the last test(where I was testing about the minus sign feature in the display number function)

#

however now it has no output for some reason

#

the last test worked
