Why can’t I get a player’s humanoid? [Answered]

I need to access a player’s health value so I can change it, and i have this localscript in starterplayerscripts:

wait(0.1)

local player = game.Players.LocalPlayer

local playername = game.Players.LocalPlayer.Name

local playerchar = player.Character

local humanoid = playerchar.Humanoid

local hunger = player.Hunger

while true do
	wait(3)
	hunger.Value = hunger.Value - 1
end

When I run the game, it gives this error message:

Players.Quantapie.PlayerScripts.Hunger:9: attempt to index nil with 'Humanoid'

Also, I have another localscript in screengui,

wait(0.1)
local health = script.Parent

local player = game.Players.LocalPlayer

local playername = game.Players.LocalPlayer.Name

local playerchar = player.Character

playerchar.Humanoid.Changed:Connect(function()
	health.Value = playerchar.Humanoid.Health
end)

and for some reason that has no problems. Anyone know why? Any help would be appreciated. Thanks!

Alright, I'll test your code. And I'll see if I can fix it!
