GetPropertyChangedSignal not working on humanoidrootpart

[mhmdsndb3 (Printer)]

so i have this code

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local missile = game.ReplicatedStorage.missile:Clone()
		missile.Parent = workspace
		missile.Position = Vector3.new(0,1000,0)
		local head:Part = char:WaitForChild("HumanoidRootPart")
		print("connecting")
		head:GetPropertyChangedSignal("Position"):Connect(function()
			print("fired")
			missile.CFrame = CFrame.lookAt(missile.Position,head.Position)
			print("changed")
		end)
	end)
end)

it runs fine until it reaches the head:GetPropertyChangedSignal("Position"):Connect(function()
part where it doesnt connect the function

[LegendPX_Taken (Math)]

you should change the position after connecting the event

your code

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local missile = game.ReplicatedStorage.missile:Clone()
		missile.Parent = workspace
		local head:Part = char:WaitForChild("HumanoidRootPart")
		print("connecting")
		head:GetPropertyChangedSignal("Position"):Connect(function()
			print("fired")
			missile.CFrame = CFrame.lookAt(missile.Position,head.Position)
			print("changed")
		end)
	end)
end)

game.Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local missile = game.ReplicatedStorage.missile:Clone()
		missile.Parent = workspace
		local head:Part = char:WaitForChild("HumanoidRootPart")
		print("connecting")
		head:GetPropertyChangedSignal("Position"):Connect(function()
			print("fired")
			missile.CFrame = CFrame.lookAt(missile.Position,head.Position)
			print("changed")
		end)
		missile.Position = Vector3.new(0,1000,0) --only change
	end)
end)

what is the point tho it doesnt do anything(sorry for late response i accidently slept)

[ForeverSp4rK (SpArK)]

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local missile = game.ReplicatedStorage.missile:Clone()
		missile.Parent = workspace
		missile.Position = Vector3.new(0,1000,0)
		local head = char:WaitForChild("HumanoidRootPart")
		local lastPos = head.Position

		RunService.Heartbeat:Connect(function()
			if head.Position ~= lastPos then
				missile.CFrame = CFrame.lookAt(missile.Position, head.Position)
				lastPos = head.Position
			end
		end)
	end)
end)

i tried to avoid that method but ig i will just use it

[mhmdsndb3 (Printer)]

btw what is the point of the last position varible

[ForeverSp4rK (SpArK)]

Ok then make a part like the humanoid root part and weld it make it unvisible and untouched and canquary false then name it like humanoid position detector then u can use the GetPropertyChangedSignal

[uDavidII (NotDavid)]

creating a new function every time the player character is added is the best way to make a memory leak, if the player dies 50 times, it will have 50 heartbeat function’s working,

literally your game gonna crash so hard.

Probally this is the best way for u:

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

--// Function's
local MoveDirectionTable = {}

Players.PlayerAdded:Connect(function(plr)
	plr.CharacterAdded:Connect(function(char)
		local Humanoid = char:FindFirstChildWhichIsA("Humanoid")
		
		local missile = game.ReplicatedStorage.missile:Clone()
		missile.Parent = workspace
		missile.Position = Vector3.new(0,1000,0)
		
		local head = char:WaitForChild("HumanoidRootPart")
		local lastPos = head.Position
		
		if MoveDirectionTable[char] then
			MoveDirectionTable[char]:Disconnect()
			MoveDirectionTable[char] = nil
		end
		MoveDirectionTable[char] = Humanoid:GetPropertyChangedSignal("MoveDirection"):Connect(function()
			if head.Position ~= lastPos then
				missile.CFrame = CFrame.lookAt(missile.Position, head.Position)
				lastPos = head.Position
			end
		end)
		
	end)
end)

Oh ye this is perfect!! Ye good idea using the move direction is better!
