GetChildren() is not selecting the desired part?

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    GetChildren() is printing an other part when it’s suppose to print its desired part
    example:

i have a part that was put in the folder called “1”

print(source[targetPos]) is going to print the first object in the table, not the part called 1. Use print(table.find(source, targetPos))

Thats because its choosing from the first part of the table which will not return the part you want (unless there is only 1 part)

So i would suggest you doing this:

local source = game.Workspace.Map.Roads.Road:GetChildren()
for i,v in pairs(source) do
        if v.Name == "1" then
                source = v
                break
        end
end

What will this do is that it will run a for loop where it searches for all items in the Road folder/model until it finds a folder named “1” then it will assign the source variable as that folder and then breaks the loop

Thats pretty much the same thing

It’s printing nil. also for @zaydoudou i dont wanna do i,v pairs but if there’s any other way; can you pls tell me? if not then i’d have to do i,v pairs then. :confused:.

6

Yes, there is another way. Try doing print(source[table.find(source,"1")].Name)

7

It’s printing nil and i don’t know why…?
(is there another way other than for i,v)?

8

Oh wait my bad. I was searching it using a string instead of a part so i can’t use table.find()

9

I also tried it with targetPos as a number, it still prints nil. maybe i am doing table.find() wrong?

10

My easiest solution is to use for i,v in pairs

11

does a numeric getchildren() loop works with this too?
Example code:

for i = 1, #source do
       
end

or will it get the same error as the "print(source[targetPos])?

12

It doesn’t work since you can’t use it to identify the folder’s name

13

Ahhhhh
alright, i get it. im just gonna do for i,v pairs >:( this worked before and now it doesnt maybe because the folder before was arranged perfectly.
folder:
1 - first (this is targetted first bcuz it’s called in source[targetPos]
2 - two (now called second.)
but the folder got messed up
new folder:
2 - first(wasn’t suppose to be targetted first.)

1 - second(was suppose to be targetted first).
so i think that sums up what’s happening. i gotta make another function for i,v pairs then.

edit(it’s still in the same position as the old one. my bad i thought the folder was arranged wrong.)

14

another problem.

for i, target in pairs(source) do
	if target.Name == targetPos then 
		print(target.Name)
		--position = target.Position
	end
end

it’s not printing the target name. why?
edit: I realised the targetpos isn’t a string.

15

Because its checking if the target’s name is a number.

Try doing if target.Name == tostring(targetPos) then

That worked!, now i can finish the zombie targetting tower part.
