This doesnt work im gonna go insane

[molten thicket]

output doesnt print anything

The other tags work

[languid vessel]

u gotta wait

the script is local which is run in client side

and client do not load everything instantly

[molten thicket]

but it works with other tags

[languid vessel]

it also has to do with streaming service

[languid vessel]

it loaded

try to add task.wait()

[molten thicket]

alr

thanks man

[molten thicket]

well i try to use game.isloaded but it doesnt work

and adding task.wait in the start of the script feels like a bad habit

[languid vessel]

u can use :GetInstanceAddedSignal(name)

so when an object load

it fire the signal

local CollectionService = game:GetService("CollectionService")

local function block_added(block)
  ... -- pretend code here
end

for i, block in CollectionService:GetTagged("Block") do 
  block_added(block) 
end

CollectionService:GetInstanceAddedSignal("Block"):Connect(block_added) -- block added 

[languid vessel]

@molten thicket here's an example

it'll work like you expected but without using task.wait()
