Problem with CollectionService

Help and Feedback Scripting Support

Hello! I was trying to learn how to use CollectionService and I have one question about it. Basically, whenever I tag an instance, as you can see in my code below, and right after that call a GetTagged function, it doesn’t get the instance I tagged. If I put a wait() between these operatiions, it suddenly works. My question is, why?

local PL = game:GetService("Players")
local COLS = game:GetService("CollectionService")
local DEBRIS = game:GetService("Debris")


PL.PlayerAdded:Connect(function(player)
	
	local char = player.Character or player.CharacterAdded:Wait()
	if char then
		
		print(char.Name)
		COLS:AddTag(char:WaitForChild("Head"), "SUS")

		--wait(1) - if I add a wait in there, it works. Otherwise, it doesn't.
		
		for i, v in pairs(COLS:GetTagged("SUS")) do
			
			print(v.Name)
			DEBRIS:AddItem(v, 3)
			
		end
	end
end)

Thanks for your time. :blue_heart:

Because you can’t add a tag and get all the tagged parts at the same time it needs a wait(Number) else it returns no Instances with that tag

So I NEED to use wait() in case I want to get the tagged instances?

That is correct. You need to yield the script for a second or two and let the game know that a new tag is being created for that certain object, otherwise if you try looping through it instantly it will skip the item you just added. However if you wanted you can just get their head and delete it too like this

PL.PlayerAdded:Connect(function(player)
	
	local char = player.Character or player.CharacterAdded:Wait()
	if char then
		
		print(char.Name)
		COLS:AddTag(char:FindFirstChild("Head"), "SUS")

		
		DEBRIS:AddItem(char:FindFirstChild("Head"), 3)

		for i, v in pairs(COLS:GetTagged("SUS")) do
			
			print(v.Name)
			DEBRIS:AddItem(v, 3)
			
		end
	end
end)

Okay, thanks a lot. I know I could delete their head just with Debris but I wanted to practice a bit the CollectionService. Again, thanks to everybody who replied.

Yeah, unfortunately this is the only way you’d be able to do it instantly. Otherwise if you tagged this from another part in your script and called a function that loops through it, that would work. At least it should… :thinking:
