Why wont this Emit the particles?

[lucid sapphire]

Title

[brisk fulcrum]

:GetDescendants() doesn't need any parameters and returns a table containing all descendants within the part. Use :FindFirstChild() or :WaitForChild().

[lucid sapphire]

Im trying to get several Particle emitters is the thing

I know its very disorganized but I need each of these in several parts with most of them on attatchments in other parts

[brisk fulcrum]

Use LightningStrike and get the descendants, loop through the table, check if instance is a particleemitter using :IsA() then call Emit

[lucid sapphire]

How would I do that

Or where does the :IsA go?

[brisk fulcrum]

second argument of the for loop

[lucid sapphire]

Im confused Sorry

[brisk fulcrum]

do you know how to use for loop

[lucid sapphire]

Kinda

Not enough

[brisk fulcrum]

how about you show me how you use for loop

start by number increment

[lucid sapphire]

Im Still Relatively new, If I saw a For loop I could identify it but I really dont know how to use it

[cunning oar]

** You are now Level 10! **

[brisk fulcrum]

the code you provided have while loops, you know how to use it?

[lucid sapphire]

while true do

I know that loops

[brisk fulcrum]

fundamentally, what does the while loop needs to run?

[lucid sapphire]

It needs to be True? Like it needs the "true" to be true

[brisk fulcrum]

What about true, what are they?

[forest badger]

recommend read every page in this article https://create.roblox.com/docs/tutorials/fundamentals/coding-1/coding-fundamentals

[lucid sapphire]

I have no clue

[brisk fulcrum]

Learn the fundamentals, Pyro-Fire have given the link for you

[lucid sapphire]

I'll try but im kinda on a time crunch because of the Jam

Okay I think I kinda get it

so If I want it to emmit on an increment

for count 0, 1 do
wait(5)
feedbackSound:Play()
P1:Emit(EMIT_AMOUNT)
end

And that would continue looping it

because I dont have a 3rd number

or I got my two confused and it needed to be 1, 0

[brisk fulcrum]

you don't need to make it on for loop increment

I was jsut asking if you know how to do it

[lucid sapphire]

Oh

[lucid sapphire]

Did I get this right atleast?

[brisk fulcrum]

well yes but you're missing equal sign on the first argument

[lucid sapphire]

Right yeah

Okay

How Will that help with my original issue

[brisk fulcrum]

do you know tables

[lucid sapphire]

Not Really

[brisk fulcrum]

tables are multi-variable container. they use index and value, which can be number or letter (string). Index as the variable name and value as, well you know

[lucid sapphire]

Mhm

[brisk fulcrum]

you can use table in for loop by doing for a, b in c where c is the table argument

[lucid sapphire]

Okay

[brisk fulcrum]

the for loop will iterate through that table, giving a as the index and b as the value

do you know if statement?

[lucid sapphire]

if ( ) true do?

Or false

[brisk fulcrum]

you dont need true or false,

well, the if statement wants to know if its true or false, but in this case, you call it a conditional

so if (a == 1), where a is 1. the conditional will return true

if a is not 1, it will return false

[lucid sapphire]

so

[brisk fulcrum]

making the if statemnt will not run the code

[lucid sapphire]

for 1, 5 in 5
if a == 2
end

Ill get false?

[brisk fulcrum]

yes

well not in that case

[lucid sapphire]

If it was written correctly

[brisk fulcrum]

the second loop will turn true

[lucid sapphire]

So it adds to A after every loop?

[brisk fulcrum]

let me recall

for A = 0 (variable), B = 1 (this is end count), C = 1 (Steps) do

[lucid sapphire]

So It'll do one loop, causing A = 1 and B = 1, And Because theyre the same now It would stop

[brisk fulcrum]

yes

[lucid sapphire]

Got it

[brisk fulcrum]

if the end count is 5

a + 1, until it reaches 5

since the step is 1

if the step count is 2

a + 2 until 5

[lucid sapphire]

Ah

[brisk fulcrum]

though the code will add 2 times only since you can't add 2 more than 5

[lucid sapphire]

for 0, 5 in 1
if a == 2
end

That'll end on the second loop

But if I switched it to a == 5 it'd end on the fifth

or is It adding two because of the a == 2

[brisk fulcrum]

no

c

c is step value

[lucid sapphire]

got it

So It would end on the fifth loop for a == 5

That makes sense

[brisk fulcrum]

althought you have to be careful with the variable you set it to

when you set a = 0, the for loop will run another time until it reached the end count

basically making it run 3 times instead of the actual end count

[lucid sapphire]

Mhm

[brisk fulcrum]

this is teh correct way

[lucid sapphire]

Alright

[brisk fulcrum]

now you got the basics of the for loop

[lucid sapphire]

Yes

[brisk fulcrum]

lets move to solving your emitter problem

Since your particles are within a folder, we can use :GetDescendants(), calling it from the folder object to get the descendants of objects within the folder

we can use that table and iterate it using for loop

[lucid sapphire]

So this?

[brisk fulcrum]

Yes!

[lucid sapphire]

Okay

Where would the For loop go then?

[brisk fulcrum]

what does A variable give us

when you iterate through table

[lucid sapphire]

The amount of times the loop has run, or like the starting value

[brisk fulcrum]

well thats a different case

i mean

ok that is

what does B give us

[lucid sapphire]

The end goal

The amount of times we want it to run, or the end value

[brisk fulcrum]

mmm in this case it doesn't

you're iteratible a table

they contain index and value

[lucid sapphire]

Mhm

So what would B be in this instance?

[brisk fulcrum]

im sure you know

i jsut told you

[lucid sapphire]

Sorry Im a bit confused

[brisk fulcrum]

what does a table contain

[lucid sapphire]

Index and Value

[brisk fulcrum]

Great, now when you put it into a for loop, what does the loop do to that table?

[lucid sapphire]

I feel like my guesses are wrong

Either Load everything in the table or check if all of it is there

[brisk fulcrum]

i think you're getting confused

for loops have different use-cases

refer to this

[lucid sapphire]

Im really not getting it

[brisk fulcrum]

ask me

what is it that you're not getting

[lucid sapphire]

Im confused on what the loop is doing to the table

I can see that its looping 4 times

Is it printing each object each loop?

[brisk fulcrum]

which for loop

lower or the upper

[lucid sapphire]

Upper

[brisk fulcrum]

yes

[lucid sapphire]

And lower is printing the current number of loop

[brisk fulcrum]

yes

[lucid sapphire]

Okay

So Each loop

Would print each object once

and A is the number of loops

That makes a bit more sense

[lucid sapphire]

The printed number

[brisk fulcrum]

the for loop wouldn't print the object once, look in the table, how many variables does it have?

[lucid sapphire]

It has two

So would it print both objects per loop?

[brisk fulcrum]

Yea

Its basically the same as the lower for loop

but used in table

[lucid sapphire]

How can I use that in the solution to my problem?

[brisk fulcrum]

GetDescendants() returns a table containing objects, the loop will iterate that table and return value as the objects

[lucid sapphire]

Am I putting "ParticleEmitter" in the Get Descendants or is it not neccesarry?

[brisk fulcrum]

unneccessary since the function doesn't need any argument

[lucid sapphire]

Okay

[brisk fulcrum]

what GetDescendant basically do is, it'll use the object that called the function, store every object exists within that object into a table

[lucid sapphire]

Mhm

[brisk fulcrum]

now that we have value, we use if statement to know if the object is SPECIFICALLY a ParticleEmitter object using :IsA() inside the table for loop

try writing the code

[lucid sapphire]

I thought this

But the table is saying wrong

[brisk fulcrum]

You got it right

replace that table with folder and the descedants function code

[lucid sapphire]

So this?

[brisk fulcrum]

nnno

oh wait

[lucid sapphire]

Because P1 is equal to the get Descendants function

[brisk fulcrum]

yes it is correct

try running the code

[lucid sapphire]

I did and it worked, But

Where would I put the wait inside of the loop?

Inside the if?

Or before it

[brisk fulcrum]

before it

basically anywhere specificly

just not in the statement code blocks

[lucid sapphire]

Okay, Can I write a "While True Do" for the sound and have it be the same wait as the for loop?

Or will it need to be all in the same thing

[brisk fulcrum]

no

you want it to play with the effect, so where do you put it?

[lucid sapphire]

In the for loop

[brisk fulcrum]

mm no

GetDescendants() returns every object within the folder, your folder could have parts, attachments, etc

[lucid sapphire]

Mhm

[brisk fulcrum]

the for loop will run EVERY object it iterate

so you want it to run specificly for particleemitter

we checked the object is a particle emitter

we wwant the sound to play with the emitter

[lucid sapphire]

Yes

[brisk fulcrum]

so where?

[lucid sapphire]

Outside of it

[brisk fulcrum]

in the for loop or the if statement

[lucid sapphire]

In the loop, not in the if

[brisk fulcrum]

That'll make the sound run every object it searched but not specificly the emitter which what you wanted

[lucid sapphire]

Mhm

So where would it go?

[brisk fulcrum]

the if statement

[lucid sapphire]

It

kinda worked

Its not using every emitter

[brisk fulcrum]

can i see your full code

[lucid sapphire]

Theres the code and video showing what I mean

The video doesnt have sound

but the sound played when the effect played

its just that not all of it played

[brisk fulcrum]

Oh you want all the particle to run every 5 second?

[lucid sapphire]

Yes

The full effect

[brisk fulcrum]

use while loop and place wait() below it. place the for loop code inside the while loop, remove the wait code in the for loop

[lucid sapphire]

This?

[brisk fulcrum]

Yup, the while loop will act as a continous loop to call the for loop emitting the particles

[lucid sapphire]

That works!!

[reef pond]

Instead of wait() do task.wait() also you can just while task.wait(5) do instead of extra true

[brisk fulcrum]

also works

[lucid sapphire]

Thank you!!!!!!

And thanks for the small lesson :)

[brisk fulcrum]

totally didn't spend 1 hour of my life teaching a newbie

[reef pond]

A hour!?!?

dang

the dedication 💪

[brisk fulcrum]

And please, learn the fundamentals to fully understand programming and the functionality of Roblox Studio

[reef pond]

✅

[lucid sapphire]

I will, Its my first time doing stuff on Roblox Studio in the past couple months, The last thing I worked with was Camera movements and I havent worked with particle code much

[reef pond]

also, just so you know, immediately begining to emit after parenting to workspace won't work, you need to task.wait(0.1) before emitting or else clients won't catch up, said this because i had this annoying issue i couldn't resolve for a day
