i cant get a simple button to work

[woeful pawn]

i've been trying to get into coding, and i thought that getting my character to jump or sit with a button would be simple. but i just cant get it to work, i've tried every source, this server, google, reddit, nothing helps

here's my code

local button = script.Parent
local players = game:GetService("Players")
local function sit ()
local player = players.LocalPlayer
local character = player.Character
if character then
local humanoid = character:FindFirstChild("Humanoid")
if humanoid then
humanoid.Sit = true
end
end
end
button.MouseButton1Click:Connect(sit)

Any errors?

[woeful pawn]

no, the code's clean, but when i click the button nothing happens

[runic moth]

Do you have the output open?

[woeful pawn]

no, im still very new, how do i do that?

[runic moth]

View-> output

In the top bar on studio

[woeful pawn]

oh dang, i didnt know about this

[runic moth]

Any red lines when running?

[woeful pawn]

i got this: Players.maykonrbds1.PlayerGui.ScreenGui.sit button.Script:5: attempt to index nil with 'Character'

it was red

[runic moth]

Do you have the explorer open?

[woeful pawn]

yes

** You are now Level 1! **

[runic moth]

mind telling me the color of the script icon?

[woeful pawn]

its white

i also tried using local script, that didnt work

[runic moth]

Copy the code (the text), delete the script

Then add in a local script

[runic moth]

Probably some different error then

[woeful pawn]

alr

im going to try that

[runic moth]

But let’s first change it over to a local script

Then run it again and tell me the next error

[woeful pawn]

omg

it worked

i know its not your job, but could you tell me the difference between local script and just script?

[runic moth]

Well it’s mainly the runcontext

You have the server and the client. Server scripts run only on the server, these can’t be altered by players but also can’t take inputs as easily

Local scripts run per client. These will add some things for one to take inputs (e.g. pressing a button). This will also add the ability to use .LocalPlayer

im still pretty confused, but i think i get it

honestly, just being able to see the output of my scripts is already very helpfull

thank you very, very much!

[runic moth]

Oh it is. Only real way you know what’s wrong with it

A hint: the most common error you’ll encounter is

blabla attempted to index nil with X

This means you have a line like

…Y.X…

This does NOT mean X doesn’t exist, this means Y doesn’t exist

Very common mistake but very useful to know

[woeful pawn]

im sure that'll make more sense as i get used to scripting, but thx

[runic moth]

Just remember it the next time you see that error

It will make more sense when you encounter it

[woeful pawn]

alr, im going to go back to messing around in roblox studio, this helped a lot, thank you

8 hours of trying to get a code to work, and all i needed was to change 1 simple thing

[runic moth]

When I first started programming I once took 12 hours on a 3 line code

It will get better

Ok so think of it this way:

Local script is like on the side of your device. It is to do with YOUR player and can interact with your player and what it does. Eg. Game.Players.LocalPlayer:Kick(“Haha get better”) - the script only works on a local script, because it is dealing with the client, your account.

A script is what deals with server-wide events that may affect every player. Eg: local NewPart = Instance.new(“Part”) - it only works on server side, as it is to do with EVERYONE

TL;DR: local script = you. Normal script = server

Pro tip: if something isn’t working, after every line or block of code, do print(“[what you are trying to accomplish goes here] completed”)

For example if I was doing a script that makes a part bigger I might do this -

local function MakePartBigger()
— code goes here
End
Print(“MakePartBigger Successful”)

[runic moth]

That print should be located i side the function, else it doesn’t print when the function finishes. It now prints when the function gets declared (functions first get declared and later get called (which is when they run))

Oh yes, my bad

I have been coding for years, I’m still not good
