Problem with smooth camera

this code for smooth camera. After the character’s death, the script stops moving the camera smoothly

[markjac]

The reason the camera script stops working when your character dies is because the HumanoidRootPart disappears. When your character dies.

So you can listen for changes to the Character property of the player and reattach the camera script accordingly.

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

local player = Players.LocalPlayer
local camera = workspace.CurrentCamera

local XOffset = 0
local YOffset = 0

function lerp(a, b, c)
	return a + (b-a) * c
end

local function onCharacterAdded(character)
	local humanoidRootPart = character:WaitForChild("HumanoidRootPart")
	
	RunService:BindToRenderStep("MoveCamera", Enum.RenderPriority.Camera.Value, function(deltaTime)
		if not humanoidRootPart then return end
		
		local flatCamLookVector = (camera.CFrame.LookVector * Vector3.new(1,1,1)).Unit 	
		-- flat camera vector (no Y axis)
		-- So the X and Z movement is relative to the camera
		-- but the Y is relative to the world

		local flatCamCFrame = CFrame.new(Vector3.zero, flatCamLookVector) -- cframe from the flat vector
		local localMovement = flatCamCFrame:VectorToObjectSpace(humanoidRootPart.Velocity / 16) -- turn velocity from world to the flat camera cframe
		local xMovement = localMovement.X -- calculate the X movement based on the camera
		local yMovement = localMovement.Y -- calculate the Y movement based on the camera

		XOffset = lerp(XOffset, xMovement, math.pow(0.2, deltaTime * 60)) -- interpolate for smoothness
		YOffset = lerp(YOffset, yMovement, math.pow(0.2, deltaTime * 60)) -- interpolate for smoothness
		-- see https://www.construct.net/blogs/2/924 for delta time implementation

		camera.CFrame = camera.CFrame * CFrame.new(0, 0, 0) + flatCamCFrame.RightVector * -XOffset + flatCamCFrame.UpVector * -YOffset -- add negative offset to camera CFrame

local function onCharacterRemoving()
	RunService:UnbindFromRenderStep("MoveCamera")
end

player.CharacterAdded:Connect(onCharacterAdded)
player.CharacterRemoving:Connect(onCharacterRemoving)

-- Initialize with the current character if it exists
if player.Character then
	onCharacterAdded(player.Character)
