Script cant find char.Torso for trail

Help and Feedback Scripting Support
#1

Hi im trying to make a player trail and i have tried using many different scripts but every time it fails to find char.Torso or char.Head etc

local Trail = game.ServerStorage["RainbowTrail"]

game.Players.PlayerAdded:Connect(function(plr)
	
	plr.CharacterAdded:Connect(function(char)
		
		local plrTrail = Trail:Clone()
		
		plrTrail.Parent = char.Torso
		
		plrTrail.Attachment0 = char.Head.FaceFrontAttachment
		plrTrail.Attachment1 = char.Torso.WaistBackAttachment	
		
	end)	
end)

Heres the code im using. Does anyone know how to fix this? Thankyou!!

If your character is r15, this will not work
this is the universal way to do it (works with r15 and r6)
if its mainly r6 then change the rootpart below to torso if you want

local Trail = game.ServerStorage["RainbowTrail"]

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local RootPart = char:WaitForChild('HumanoidRootPart')
		local Head = char:WaitForChild('Head')
		local plrTrail = Trail:Clone()
		plrTrail.Parent = RootPart
		plrTrail.Attachment0 = Head.FaceFrontAttachment
		plrTrail.Attachment1 = RootPart.WaistBackAttachment	
	end)	
end)

replace the attachment1 line with this

local attachment1 = Instance.new('Attachment', RootPart)
Attachment1.Visible = false
Attachment1.CFrame = CFrame.new(0, -1, 0.5, 1, 0, 0, 0, 1, 0, 0, 0, 1)
plrTrail.Attachment1 = attachment1

alright i have been thinking for quite a while now but here u go

local Trail = game.ServerStorage["RainbowTrail"]

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local Head = char:WaitForChild('Head') -- will wait until the head is loaded, at that time the code below will be yielded by this function, using waitforchild on something that doesnt exist will yield infinitely
		local Torso = char:FindFirstChild('Torso')
		local LowerTorso = char:FindFirstChild('LowerTorso') -- both has waistbackattachment
		local plrTrail = Trail:Clone()
		if Torso then
			plrTrail.Parent = Torso
			plrTrail.Attachment1 = Torso.WaistBackAttachment
		else if LowerTorso then
				plrTrail.Parent = LowerTorso
				plrTrail.Attachment1 = LowerTorso.WaistBackAttachment
			end
		end
		plrTrail.Attachment0 = Head.FaceFrontAttachment
	end)	
end)

The problem was the character wasn’t fully loaded yet
Adding a wait at the start fixed it…

local Trail = game.ServerStorage["RainbowTrail"]

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		task.wait()
		
		local Head = char:FindFirstChild('Head') -- will wait until the head is loaded, at that time the code below will be yielded by this function, using waitforchild on something that doesnt exist will yield infinitely
		local Torso = char:FindFirstChild('Torso')
		local LowerTorso = char:FindFirstChild('LowerTorso') -- both has waistbackattachment
		local plrTrail = Trail:Clone()
		if Torso then
			plrTrail.Parent = Torso
			plrTrail.Attachment1 = Torso.WaistBackAttachment
		elseif LowerTorso then
				plrTrail.Parent = LowerTorso
				plrTrail.Attachment1 = LowerTorso.WaistBackAttachment
		end
		plrTrail.Attachment0 = Head.FaceFrontAttachment
	end)	
end)

if not Player:HasAppearanceLoaded() then Player.CharacterAppearanceLoaded:Wait() end
To yield the script until the player’s character’s appearance has loaded.
