Could you be able to dm me or to create

[runic egret]

Just use a thread.

[faint night]

Perfect

Ok, correct me if i'm wrong

A JSON always is between two {} and in this case there are 4:

two for results

nono, i'm wrong

cause there are more

i dont get why there are two JSON...

[blissful shoal]

This is an object containing another object

Because one object contains the other

[runic egret]

JSON is a way to encode data.

It is made up two major components

objects and arrays

[severe crest]

an object always starts with {}

[runic egret]

An object is wrapped in { curly braces }. It is made up of name-value pairs.

{ "foo": 1, "bar": 2 }

This has two name-value pairs: "foo" and 1. "bar" and 2.

An array is wrapped in [ square brackets ]

[faint night]

and why does satatus doesn't have curly braces?

[runic egret]

Because its value is neither an object nor an array.

It is a simple value.

A string value, to be specific.

[blissful shoal]

they probably structured it this way so they could do this:

{
  "results" : {
    // a bunch of data
  },
  "status" : "success"
}```
or
```json
{
  "results" :  null,
  "status" : "error"
}```

[runic egret]

You're putting a lot of emphasis on the existence of "curly braces" here

[blissful shoal]

but it doesn;t relaly matter why it's just how they chose to structure it

[runic egret]

you shouldn't be thinking "JSON is when braces"

They are simply how you denote an object.

You don't just add lots of curly braces everywhere to make it JSON or something

If I serialize a List<int>, it'll look like this in JSON:

[1, 2, 3, 4, 5]

If I serialize an int, I'd get...

5

literally just 5

[blissful shoal]

Yep! JSON basically has 4 datatypes:

• numbers which look like 5.332
• strings which look like "example"
• objects which look like:

{
  // any data you want in here
}```
- arrays which look like:
```json
[1, 3, 5, 2, 6]```

and every piece of data has a name
so in this case you have "results" which is an object and "status" which is a string

[runic egret]

Objects and arrays are what allow you to store something more complex than a single value.

You almost always are, hence why you almost always see { curly braces } and [ square brackets ]

[runic egret]

along with true, false, and null

https://www.json.org/json-en.html

the entire spec is extremely short

[blissful shoal]

true

[runic egret]

You should really just go make some small classes and see what they look like when serialized.

I think it will help you to get a mental model.

[faint night]

ohh

[faint night]

Really usefull to know that

[faint night]

The problem is where to find them...

[runic egret]

Nowhere

Just make them up

Make a class that holds an int. Serialize it

Then make a second class that holds an instance of the first class

[faint night]

oh, sorry i thought you were saying like courses

[runic egret]

Ah

Wrong kind of class :p

[faint night]

i think i'm getting it... the json response contains two big groups

this one

and this one

that's why there are here to big groups

a class containing all that strings

and just a single string

[severe crest]

they're 2 objects in this case, which in c# translate to a class/struct

[faint night]

yep

and when i have a class in a class

i need to serialize that class?

Or when i serialize the top one it serializes the rest automatically

[severe crest]

I mean if you wanted to Results class definition itself, could've just been outside of Sundata
the object SunData which has results and status are the only ones needed inside ,
ofc you have to define the fields of results object , which you did but yeah the class itself can be defined in another file even.

[runic egret]

The entire thing gets serialized.

Every class involved must be marked as Serializable, but that’s it

[faint night]

and just to confirm

that is not possible right?

[severe crest]

no

[faint night]

good

now can I say that i more less know how it workss!!! <:

[severe crest]

you can technically do this I meant earlier

[Serializable]
public class Sundata
{
    public Results results;
    public string status;
}
[Serializable]
public class Results
{
    public string sunrise;
    public string sunset;
    public string etc;
    public string etc;
    public string etc;
}```

[runic egret]

You want to think about the “shape” of the data

The response from the server isn’t just one big flat object

It’s an object that has another object in it

[severe crest]

I love working with BSON for db

[runic egret]

I might switch to that for my soulslike game

Lots of 128-bit UUIDs that’d be really darn efficient in binary

as compared to their current hex encoding

I should really do base64 at the least…

[severe crest]

I got this dataset that was in TSV file it was over 1Gb

moved it to BSON it was like 36kb

lmao

[faint night]

but in that case would be necesary to write this? cs public Results results; on the first class?

[severe crest]

yes ofc

your server response looks for it

[runic egret]

Yes. The object contains another object.

So your class needs to have a field that stores another class

[severe crest]

aka objects in json

[runic egret]

SunData contains a Results

Therefore, it must have a Results field

[faint night]

Get it

[runic egret]

If you omit this field, then SunData will just contain the status string and nothing else

{ "status": "foo" }

[severe crest]

yup. wouldn't be very handy lol

[severe crest]

status was rightfully separated from the Results, by whoever made the original object

[faint night]

is that kinda JSON file?

[runic egret]

it's a similar concept, at least

except that it doesn't use human-readable text

[severe crest]

just means Binary instead of Javascript

so yeah pretty much

[runic egret]

JSON is only allowed to use printable characters

[severe crest]

its just overly optimized for size/speed

[runic egret]

open a jpeg in a text editor to find out what non-printable characters look like

It's more efficient.

[faint night]

i've seen that there are a way to convert json content into binary... is that the same?

[runic egret]

For example, a 32-bit integer can be stored in 4 bytes

But if you want to encode that integer in JSON, you must write it out as a number using the 0-9 digits

That can take ten characters, so 10 bytes of space

[faint night]

I really appreciate it very much for explaining to me how JSON files works

[severe crest]

they're very handy / powerful

thats why they're pretty much everywhere

[faint night]

sure, i started learning them to get the sunset time on a location, and know i like them hehe

and And thanks to you, I know i don't need all that to increase performance

and i can just leave it like this

just an out of curiosity question, how did you created this threat?

[severe crest]

right click on any message Create Thread or the Plus button on discord

[severe crest]

not sure about performance wise lol you're still downloading all the data in this case, its just neater without all the needed fields cluttering the model object

[faint night]

oh, another thing, i forgot to ask you what does exactly do the serializable atributte? i know it must be there, but i dont know what it does...

[faint night]

hehehe

[faint night]

Thanks

[severe crest]

it marks the class as able to serialize , for binary or json or w/e

https://learn.microsoft.com/en-us/dotnet/standard/serialization/

[faint night]

I don't even know what serialize a var does appart from it makes it vissible on the inspector...

[severe crest]

thats just inside unity, there's more to it else where, on that link it explains more or less.. its a bit of a heabust . Not something you should worry at this moment

[faint night]

thanks for the info

i'll take a look

...and to your video too

[severe crest]

oh right those are there too forgot
Ironically those are one of the only few videos I don't do any sort of explainations of code and just plow through showing code no commentary 😅
I need to redo it as its not very useful learning tool

[faint night]

bruhh, i'll be waiting for it hehe

[severe crest]

thanks! I'm writing a simple blog while thats in the works though, just find it easier than using my voice.. ughh I kinda envy those youtubers with extrovert enough personality to make vids , but I try push myself not be hermit 🥹

[faint night]

Every single person do it the better way for them...
