Trouble using wait for child and optimizing load time on localscripts ?

Hi, im trying to implement :WaitForChild for its primary purpose (probably dont need to explain). However, i have two dilemas. 1. When i call the following code, I get a "Character" == nil --> error " attempt to index field 'Character' (a nil value)"

game:GetService("Players").LocalPlayer.Character:WaitForChild("LeftLowerLeg")
--repeat wait() until game.Players.LocalPlayer.Character.LeftLowerLeg
local feet = game:GetService("Players").LocalPlayer.Character.LeftLowerLeg
print("destroy")
wait(1)
feet:Destroy()

I tried to get past this by adding more wait for childs but i then got an infinite yield warning/error on trying to find the localplayer.

game:GetService("Players"):WaitForChild("LocalPlayer")
game:GetService("Players").LocalPlayer:WaitForChild("Character")

game:GetService("Players").LocalPlayer.Character:WaitForChild("LeftLowerLeg")
--repeat wait() until game.Players.LocalPlayer.Character.LeftLowerLeg
local feet = game:GetService("Players").LocalPlayer.Character.LeftLowerLeg
print("destroy")
wait(1)
feet:Destroy()

How do i fix this? Thanks

Update 2: I managed to get it working by messing around with the code and types of wait mechanisms. Here is the finished code.

repeat wait() until game.Players.LocalPlayer.CharacterAdded	

local feet = game:GetService("Players").LocalPlayer.Character.LeftLowerLeg
print("destroy")
wait(3)
feet:Destroy()

Hi Gunt_r,

You could use the following snippet to ensure the script waits until the character is in game:

local player = game.Players.LocalPlayer

--you can try this vvv
repeat wait() until player.Character
local character = player.Character

--or try this vvv 
local character = player.Character or player.CharacterAdded:Wait() 

This will continue to pause the script until the character has spawned in.
