Script changing a part's color based on player health not working

Help and Feedback Scripting Support
#1

I have a part (the white part below) that should change colors when the players health changes, but it does not seem to work.

local part = script.Parent
local player = game.Players.LocalPlayer

local function changeColor()
if player.Character.Humanoid.Health >= 75 then
part.Color = Color3.fromRGB(0, 255, 0)
elseif player.Character.Humanoid.Health >= 50 then
part.Color = Color3.fromRGB(255, 255, 0)
elseif player.Character.Humanoid.Health >= 25 then
part.Color = Color3.fromRGB(255, 165, 0)
else
part.Color = Color3.fromRGB(255, 0, 0)
end
end

changeColor()

player.Character.Humanoid.HealthChanged:Connect(changeColor)
The script is located here

This line will not work in server scripts. I would advise this script:

local part = script.Parent

game.Players.PlayerAdded:Connect(function(plr)
    local function changeColor()
        if plr.Character:WaitForChild("Humanoid").Health >= 75 then
            part.Color = Color3.fromRGB(0,255,0)
        elseif plr.Character:WaitForChild("Humanoid").Health >= 50 then
            --you know the rest, just continue your original script from here but make sure to use the variable "plr"

Why won’t that work in server scripts?

#4

Because the server can’t return the local player that is playing live time on one player’s account

#5

ok. But won’t we add like speed limits there for a live player? For example if a player > 12 walkspeed there health will = 0

This isn’t @DancingCow505’s topic so we shouldn’t discuss this right now, DM me if you want to talk more
