Attempt to index Nil with 'FindFirstChild'

[frail roost]

So I'm trying to make code that will make a part point towards the cursor, and during this i ended up messing with remote events since i needed those to port over info on where the mouse is. The issue is i also want to port over the HumanoidRootPart of the player and it keeps coming up with this error message. I can't figure out what the problem is
I searched it and i know that the error message is about it indexing something that doesn't exist but it DOES exist so i'm confused
Anyone able to help?
(I started scripting yesterday so i expect this to be a really stupid mistake)

coolio

[oblique latch]

use waitforchild instead

i guess

[frail roost]

i did, that didn't fix anything

[oblique latch]

wait for the character to spawn before doing that then

i guess

If this script is in StarterPlayerScripts, you need to wait for the character, as they may not have one when the code runs.

You're correct it is.
How do i wait for the character?

[balmy cove]

local c = plr.Character or plr.CharacterAdded:Wait()

if there is you just get it, if not, you'll wait for the signal

[shrewd umbra]

local character = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:Wait()
local HumanoidRootPart = character:WaitForChild("HumanoidRootPart")

that was in the original code i read and i thought it wasn't important

[shrewd umbra]

goated

we all make silly errors

[frail roost]

as i thought this code is not what i'm supposed to be doing

icl i suck at scripting 💔

[shrewd umbra]

dw bro keep practicing

have to make errors to learn from them

[frail roost]

it's just like this is WAY too complicated, like overly so

[shrewd umbra]
