"UDim expected" IT IS A BLOXXIN UDIM.

[fossil idol]

``Luau function onTouched(hit)
if not hit or not hit.Parent then return end
local human = hit.Parent:findFirstChild("Humanoid")
if human and human:IsA("Humanoid") then
local player = game.Players:GetPlayerFromCharacter(hit.Parent)
local Gui = player.PlayerGui["Healthbar"]
local width = Gui.Healthleft.Size.Width
Gui.Healthleft.Size = UDim2.new(0, 1, (width-20), 0)
local X = Gui.Healthleft.Position.X
local Y = Gui.Healthleft.Position.Y
Gui.Healthleft.Position = UDim2.new((X-10), 0, Y, 0)
if Gui.Healthleft.Size <=1 then
script.Parent.Scriptb.Enabled = true
end
wait(0.1)
script.Enabled = false
end
end

script.Parent.Touched:connect(onTouched)```

OH YEAH

AND I CHECKED THE DOCUMENTATION

local guiObject = script.Parent
guiObject.Size = UDim2.new(0, 300, 1, 0) -- 300 pixels wide; full height of parent
guiObject.Position = UDim2.new(0, 50, 0, 0) -- 50 pixels from the left

THAT'S IN IT

LIKE

THIS IS LITTERALLY HOW U DO IT

AND IF YOU'RE GONNA SQUACK AT THE NUMBERS, IK THEY'RE PROBABLY WRONG I'VE TRIED LIKE SIX DIFFERENT SETS OF NUMBERS

CHECKING WHERE THE OFFSET IS

JBVKLJCVNXZJCXVNXDMKLJFK

Gui.Healthleft.Size = UDim2.new({0, 780}, {0, (width-20)})

EVEN TRIED ADDING THE STUPID

SQUIGGLY BRACKETS

IN THE EXPLORER

NOPE

[fringe jay]

did you mean

UDim2.new(0, width-20, 0, 100)

[glad bloom]

        local width = Gui.Healthleft.Size.Width
        Gui.Healthleft.Size = UDim2.new(0, 1, (width-20), 0)```
Size.Width is a UDim not a number, so the error is complaining about UDim-number (invalid argument #2 to subtract operation, UDim expected got number): https://create.roblox.com/docs/reference/engine/datatypes/UDim2#Width
> Width
> UDim
> The X dimension scale and offset of the UDim2.

[glad bloom]

skill issue, you just blind

you probably intended to write Size.Width.Scale

[fossil idol]

that's a thing?

oh

[fossil idol]

that doesn't work either because the scale is just 0 all the time for no reason???

I think I'll have to outsource the number keeping to a value in the workspace.

[glad bloom]

maybe you meant offset instead?

idk i'm not the one making this thing, you are.

[fossil idol]

I know right?

It's terrible!

Who would put an idiot like me in charge of this?!

oh wait that was me

well I fixed that problem but now

I have new ones

which make even less sense?!

[glad bloom]

skill issue

[fossil idol]

nah bro

I have prints and checks every step of the way

all of them are going through

it litterally says it's doing it

and it isn't

[glad bloom]

and i have a helicopter, doesn't mean i know how to drive it.

[fossil idol]

Why wouldn't you sell your helicopter then?

I mean hey give it to me I'll learn how to drive it

[glad bloom]

script.Enabled=false why

[fossil idol]

you have a helicopter?

[glad bloom]

what are you even trying to do

[fossil idol]

that's at the end of the script though?

[fossil idol]

you get hit by the lazer

the health goes down

the script deletes

another lazer with a new script spawns in to hit you

that's how it shakes down

[glad bloom]

what is Value.Value

i assume this is numbervalue and you're trying to change the value with width = Gui.Value.Value; width -= 20?

[fossil idol]

yes

[glad bloom]

okay so a numbervalue.Value is not a magic object

[fossil idol]

I don't think it is?

[glad bloom]

all you're doing is setting width to a value, then a different value. you're not changing the value contained in the numbervalue

[fossil idol]

It's a number

[fossil idol]

ohhh

that makes sense

OFC

[glad bloom]

hence, not magic

[fossil idol]

ok I thought that

it was assigning that OBJECT, of the numbervalue to the variable

how do I do THAT?

can I just not have a variable?

[glad bloom]

width=numbervalue

width.Value=newvalue

[fossil idol]

...

Thanks

[glad bloom]

and not a single one of them is plugged into anything.

[fossil idol]

dies

I mean if that's the case

I'm technically already dead

[glad bloom]

the lights are on but nobody's home ;p

its okay you're atleast making a start. this is the stuff every beginner has to learn before they can actually be called a scripter

[fossil idol]

I'm not a beginner I've just never had a reason to touch these... values before.

They disgust me

get me out of here

[glad bloom]

you're better off making these dum mistakes and learning from them than to give up and rely on chatgpt while never actually learning anything

some people make that mistake, and its far bigger than the ones you're making here ;p

[fossil idol]

I don't like using the AI, but also, when I have to do
Local A = game.workspace.thing.thingA
and go to like, F, the autosuggester is REALLY nice.

[glad bloom]

its only good for things you already know how to do

[fossil idol]

YES

IT WORKS THANK YOU

WWWW

THANKS BRUV

[fossil idol]

WAIT WAIT

one more small issue

I need a bit of help with

for some reason when the game loads 4 attacks at once it lags

which isn't much of an issue

except the lag keeps your keys held down

so you just end up walking off the edge of the thing you're riding on

ncm

nvm

I will figure it out

ohhh

I just add wait()

and the lag dissapears

marvelous

[flint python]

@fossil idol what do u mean bloxxin udim?

[pearl lynx]

** You are now Level 2! **

[flint python]

it maybe expectes udim2 or just udim. U may typed it wrong or smth

[fossil idol]

solved

[fossil idol]

I mean it's a bloxxin UDim ya bloxxer

[flint python]

Wha?
