local plr = game.Players.LocalPlayer
local character = plr.Character or plr.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local bloodOverlay = script.Parent
 
function update(newHealth)
    bloodOverlay.ImageTransparency = newHealth / 100
end)
 
update()
 
humanoid.HealthChanged:Connect(update)

This is a script inside of an image label (the blood overlay) but unfortunately does not work and am looking for answers

newhealth is supposed to be number

since you call update without a newhealth, it will probably end with no changing imagetransparency at first (no newHealth is provided) on update() to fix it just add Humanoid’s health to it and should be fixed

line 9 code

local Players = game:GetService("Players")

local plr = Players.LocalPlayer
local character = plr.Character or plr.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")::Humanoid
local bloodOverlay = script.Parent
local MaxHealth:number = humanoid.MaxHealth

local function update():()
	bloodOverlay.ImageTransparency = humanoid.Health/MaxHealth
end



humanoid:GetPropertyChangedSignal("MaxHealth"):Connect(function():()
	MaxHealth = humanoid.MaxHealth
end)
humanoid.HealthChanged:Connect(update)
update()
