can someone explain to me what a bool variable js

[fervent niche]

What does a bool variable do? I never use it because it sounds funky, and I have no idea what it does.

[outer grotto]

A bool variable just stores the information of either TRUE or FALSE

Variable = storage
Bool = True or False

[fervent niche]

I don’t understand the use of that

[outer grotto]

Example

[fervent niche]

When would I ever need that

[outer grotto]

You have a 30hz

[fervent niche]

Ok

[outer grotto]

Example you can make a button only work if the Bool is true

[fervent niche]

And how would you change the bool

[outer grotto]

Bools are literally just true and flase

I’m trying to think of the best example

[fervent niche]

What’s the point of that? Cant I just make it not work?

Or not connect the button to anything?

[outer grotto]

Let me explain first

[fervent niche]

Ok

[outer grotto]

Boolean aka Bool are True or False
This can also be seen as On or Off/Yes or No

You can use this in making something only work if the bool is true or only work if a book is false

Example a money system, you can check if your money is greater then a certain amount and if it is, it will output True but if your money is not above a certain amount it will output false

[fervent niche]

Cant I just do if: greater than, true or false?

[outer grotto]

Example, Gun handles have a bool that determines if your reloading, if your not reloading its false if you are reloading it’s true

this explains it in-game terms

When the Bool is True it explodes, when the Bool is False it dosnt explode

[outer grotto]

Example there a chip called player get is grounded it just says if your touching the ground or not

If you are touching the ground it outputs TRUE if you are not touching the ground it outputs FALSE

It’s literally just True or False

[fervent niche]

What?!

[outer grotto]

There isn’t anything complicated about it

[fervent niche]

Are the bools even doing anything in that clip?

[haughty galleon]

not the variables

theyre just there to show

Im changing the Boolean on the If chip

[fervent niche]

Then why couldn’t I just use if: player get is grounded

Then:

Wait

Is bool just an “if” chip mixed with “sequence”??

[haughty galleon]

No.

Boolean is only a yes or no

[fervent niche]

Then I’m clueless

[haughty galleon]

Its kinda like an open gate or a closed gate

[fervent niche]

I don’t see a purpose in it

[haughty galleon]

Its very important

[outer grotto]

Here’s something you will use bools for!

This is called an If chip

The red input in called the condition, this receives bools

If the bool is true it outputs from THEN

If the bool is false it outputs from FALSE

Like the five nights at Freddy remakes we’re you collect letters

You can make it so that if you have all letters it outputs true but if you don’t it outputs false

If it’s true it will execute from the then output so you can maybe award players for money

If it’s false it executes from the else output and for example you can say “you don’t have enough letters”

[outer grotto]

No

[haughty galleon]

See i use Boolean in this ivnention right here.

[outer grotto]

What?

[haughty galleon]

yeah im confused about this too

[outer grotto]

The player get is grounded has a bool output

[fervent niche]

Is this just a recreation of bool as a circuit

[outer grotto]

You then wire that to a IF chip

[fervent niche]

Is bool the red one

Int is green

Float is blue

?

[outer grotto]

Yes

bool is red

[fervent niche]

Ok…

[outer grotto]

ITS alway gonna be TRUE or FALSE

[fervent niche]

I’m saying specifically the “bool chip”

[outer grotto]

There is no “bool chip”

[fervent niche]

I mean bool variable

[outer grotto]

It works as normal as any other variable

It just saves the information True or False

[fervent niche]

How do you store stuff on it

[haughty galleon]

^

[fervent niche]

I don’t see the purpose in that

[haughty galleon]

You execute the chip

[outer grotto]

You input a Bool and execute the chip

[fervent niche]

Okay and it saves the true or false?

[outer grotto]

It will save it

[outer grotto]

yes

[fervent niche]

I don’t understand why I can’t just rerun the “if” chip

[wooden adder]

this is insane

[outer grotto]

I need to like become a better teacher bruh

I just can’t

[outer grotto]

what do you mean rerun the if chip?

[fervent niche]

Like why would I ever need to store whether something is true or false

[haughty galleon]

Yeah

you could check "If" "Player has Role"

Booleans are used right there

[fervent niche]

If player has role? Isn’t that already a chip?

[haughty galleon]

Yeah

[outer grotto]

Yo bro do you want a mini lesson? I can join you

[haughty galleon]

i didnt mean to say that chip specifically

[fervent niche]

Sure if you can

Sure if you can

Oops

[wooden adder]

I'm going to make one comment and im not explaining again

Variables are chips that store data, the data is stores is based off what variable you are using (Bool variable stores a bool value, int variable stores an int value, etc)

When you execute a variable, that variable will store whatever is being input at that moment (So if I executed an int variable that had the input "5", it would store the value "5")

All variables of the same name and type (which are inside the same circuit scope) store the exact same value

This means if I had set my int variable "MyInt" to "5", that means all int variables named "MyInt" in the exact same circuitspace would also return "5"

---

"Circuit space"/"Circuit scope" is where you are placing your circuits, by default, this is "World space", but it can also be:

• A circuitboard
• An object board
• An AI Board
• A Player Definition Board

[outer grotto]

add me now @Ardenis-

[fervent niche]

Yeah I have an idea of what it does I just don’t understand the purpose in it

[fervent niche]

Ok

Invite me

[wooden adder]

It stores a true or false value, its purpose is whatever you need it for

Want to record if the player has finished a race? bool variable, HasFinishedRace
Want to record if the player has done a one-time-event? bool variable, HasFinishedEvent
Want to record if the player is affected by a boost? bool variable, IsAffectedByBoost

[outer grotto]

join

or invite me

[fervent niche]

If a player finished a race, couldn’t I just add 1 to an Int variable, and then test if they have at least 1

[wooden adder]

Keep in mind "True" or "False" could mean anything
Yes or no, 0 or 1

Anything in code is nothing unless you define it to be something

[wooden adder]

I mean, yes, you could, but thats a waste of CPU, unless you want to record the number of times they have finished the race aswell

But for a one time event, assuming it should only happen once ever, you'd use a cloud bool variable, since you wouldnt want to record the number of times a one time event would happen

[outer grotto]

I’ve invited you and requested you like 20 times bro

[fervent niche]

Ok I’m joining

[wooden adder]

Personally, I use int variables over bool variables most the time
I only use a bool variable when I absolutely do not need an int (eg. one time event)

Any time else, I'm using an Int Variable, eg. I wouldn't have a bunch of bool variables for an AI like "IsSprinting", "IsTargetting", "IsPathing", "IsSearching", "IsWandering", I'd just have one Int Variable, "AIState"

[fervent niche]

Ok I’m in the kitchen

[fervent niche]

Ok I’ll be right back

[ripe mirage]

Like everyone explained bools are very important. a bool is Yes/No, True/False, Or Do/Don't. It's like a question on a test. "Does this equation equal to 3? 1 + 1 = 3" since it's wrong it'd be false. But if it was "1 + 2 = 3" then it'd be true. You use bools to determine if the player/server should be allowed to do this. You use books A LOT and it's very useful. You can also use bool variables to store a bool. It's not that complicated

And I swear to God if you say something along the lines of "but why would I need this?" Or "I don't understand" I am going to have a mental breakdown

[lament frost]

oh lord what happened here

[fervent niche]

I feel like people misinterpreted my question. All I wanted to know was what a bool variable did. I understand the red port I just didn’t know what the variable did

[lament frost]

It saves the value on the input

[fervent niche]

Yeah, i barely learned that yesterday, but I still don’t see a purpose in it

As opposed to giving an int to a player and testing if they have at least 1 (which is what I’ve always used)

[lament frost]

it saves time, circuits, and cpu

[fervent niche]

Yeah but I’ve never had a scenario where I’ve only wanted to set something to true/false once

[lament frost]

doesn’t have to be once

it can back to false, and go to true

like a variable called “GameActive”
Set it to true when the game starts
Set it to false when the game ends

[fervent niche]

The only purpose I’ve found in it is a button that can move a piston back and forth

[lament frost]

It’s very useful, just depends on what you’re doing

[edgy mango]

Bro says he’s good at circuits and had to have 50 messages to explain a DATA TYPE 💀

[fervent niche]

me?

[outer grotto]

It’s not my fault he didn’t get

I had to slow down for him and explain each part individually

He’s was literally unteachable in game too

[edgy mango]

💀

[wary frost]

@fervent niche The "why can't I just use greater than/equals" is actually a very good question. The answer: You can, but bool (true/false) is much faster than using numbers or strings due to how the computer processes data. In CrypticCreator's case (AIState), he has more than one thing he's tracking, so he must use a number.

You would want to store a bool in a variable when you are keeping track of something like a custom door. Is the door open? Yes/True or No/False. The next time the user interacts with the doorknob, you need to know if you want the door to open itself or close itself (using a rotator).

Sometimes there are support chips for things so you don't need to make your own bool Variable.

[fervent niche]

That’s because I already knew what the red port was, and I don’t think you knew that I knew, so when you tried explaining it to me, I was over complicating the question because I thought that you knew I knew

[wary frost]

Do you still have questions?

[fervent niche]

I don’t think so, the only question I would have is “what is the purpose in this” but it’s just a faster way of my old way… I probably won’t use the bool variable, because my brain is so set to my old method, it won’t even process a use for the new one

[wary frost]

If it is working, the only people who will notice an int vs a bool are other circuiteers and programmers. The people playing your game wont care at all.

One day when you bump into cpu overheating and really need to optimize something, you can come back and revisit it.

[fervent niche]

Okay, so that’s good. I don’t want to miss out on potential creations by not using it

[fervent niche]

Yeah, I’ll definitely keep that in mind if it overheats 👍 thank you

[wary frost]

Modern computers really let things be very "sloppy" processing-wise. 🙂

Oh! Notably: I use a bool to put a gate on an Update 30Hz, because it's faster than any other check you can throw at it. When you have a bunch of those, that little slice of cpu execution power matters.

[steep trail]

bool variable changed events

[wary frost]

I thought of a spiffy example for bool vs int when you only need a bool: Imagine you are sitting at your kitchen table and there's a fly crawling across the table. You can hit it with a fly swatter or you can hit it with a shovel. Both of these will kill the poor insect, but the shovel takes a lot more resources to wield. The bool would be the fly swatter and the int would be the shovel. You also can't dig a hole very well with the fly swatter. Different tools for different tasks.

[grand verge]

I have been summoned.

[solar willow]

Bro it should not take this long just to explain what a bool is

[grand verge]

Yeah but this is #1020094893458198578

what did you expect

[terse sage]

i have a ai. my ai will die. when my ai is dead, i save true when its hit by my sword. now the ai wont run cuz of my if.

[wary frost]

But there are lots and lots of nuances and information to consider for bools...

[fervent niche]

I know what a bool is 😭 I just didn’t know what the bool variable did

[radiant jetty]

I ACCIDENTALLY CALLED SOMEONE HERE SORRY

[grand verge]

oh well there's your answer

[lament frost]

Only 144 messages

Ong

[edgy mango]

Bro has never heard of an If condition, how tf do you know what a “bool is without knowing it” tf

[somber night]

Please organize your circuits 💀🙏

[edgy mango]

Bro I’m about to make a tutorial on CV2 I’m done with this rotating circuits bs 💀

[haughty galleon]

You’re not gonna like this but that’s as organized as it gets

[fervent niche]

I know what an if condition is 😭 I was just asking what a bool variable did that’s all!

[wary frost]

All variables just "keep information for you". i.e. store/retrieve. The data types (bool, int, float, string, Color, Player, etc.) just say how to efficiently store that information. (data types go on to tell the computer how to efficiently process computations on that information)

What you probably mean to say is "asking what a bool Variable is used for".

Answer: bool Variables are used to save information that is only ever 1 of 2 things (true/false, yes/no, 0/not zero). i.e. "is a door open or closed", "is a light on or off", "is a player moving or standing still", "is a circuit currently running or not".

[fervent niche]

Yeah I know that variables store information, I just assumed bool variable did something different because it seemed useless to store a true/false statement to me

[lament frost]

How is it useless?

[steep trail]

variable changed events

[fervent niche]

“It seemed useless” that’s why I asked

[wary frost]

Our computers currently work entirely on just a bunch of true/false bits. 🙂

[rose rune]

think of all the player get is chips, all very useful and are all bools. ‘Player Get Is Grounded’, is the player grounded? Yes or No. That’s a bool variable

try making a room, then after around 10 minutes you’ll realise how important they are

[fervent niche]

I’ve already been making a map for a month now and never once needed it

[rose rune]

have you used any if chips?

[fervent niche]

Yeah basically half my map

[rose rune]

💀

what does are the inputs on an if chip

Execute

and

Bool

[fervent niche]

What

[rose rune]

If is an bool

if is yes or no

[fervent niche]

Yeah I know that, but I didn’t know what the bool variable did

[rose rune]

then = yes, else = false

[rose rune]

oh you mean the proper bool chip?

[fervent niche]

The bool variable

[rose rune]

ok so the bool variable chip

[fervent niche]

Yeah… still don’t see a purpose in it other than to save CPU

[rose rune]

well it depends what you’re making to be honest, in some cases it’s very important, in others you don’t use it at all
