Scaling down a GUI when an object is clicked

Help and Feedback Scripting Support
#1

Hi again everyone

I want to create a “health” bar for an object, and when you click the object, the health bar will go down 1/4 of 200, which will result is 1/4 being remove from the health bar. And then, when the bar is on zero, the object gets destroyed.

I have an idea of how to destroy the object, create the GUI, add one the values, etc, etc but I just cant figure out how to change the size of the GUI by -50 each time.

Thanks everyone.

Why not just do script.Parent.Size = Vector3.new(script.Parent.Size/2,script.Parent.Size, script.Parent.Size) ?

#3

UDim2.fromScale* .

#4

I thought he wanted to size the part.

#5

I get the error

Players.pevdn.PlayerScripts.showGui:11: attempt to perform arithmetic (div) on UDim2 and number

when implementing this

(and adding msix’s changes)

#6

Are you trying to size the part or UI? In the title it says scaling GUI, yet in the text it says scaling Object.

#7

Do this:

script.Parent.Size = UDim2.fromScale(script.Parent.Size.X.Scale / 2, script.Parent.Size.Y.Scale / / 2)
#8

Oop- mean the GUI, i’ll edit it now.

#9

Oh okay yeah for Ui you use Udim2 for Parts you use Vector3

#10

All you have to do which Msix is just divide the size by 2 using Udim2

#11

by the way- does this work with a localscript?

#12

You have to set the bar to this size everytime

Horizontal bar:

Udim2.new(health/maxHealth, 0, 1, 0)

Vertical bar:

Udim2.new(1, 0, health/maxHealth, 0)

Put the bar inside another frame for background.
What this calculation basicly does is dividing the current value by max.
This provides you with a value between 0 and 100% of the max value.

10 / 100 = .1
50 / 100 = .5

it also works when the max value is higher than 100

75 / 500 = .15
100 / 450 = .22222222

because you put it in the scale 1 = 100% of its parent size.
.5 will fill the bar 50%

#14

Yes, this should be inside a local script.

#15

I was just double checking incase it would work in a server script, but now the GUI will not appear:

Here is my format:

Don’t do it in a server script, that will overload the server and cause tons of lag. Interacting with UI should be handled on the client and in some cases completely handled by the client.

#17

Its not in a serverscript, its in a local script.

#18

Can you send your full code then?

game.ReplicatedStorage.RemoteEvent.OnClientEvent:Connect(function(gui)
	local frame = workspace.Folder.kabob.BillboardGui.Frame
	frame.Size = UDim2.fromScale(frame.Size.X.Scale / 2, frame.Size.Y.Scale)
end)
#20

I guess the size of the frame isn’t scaled so try this:

game.ReplicatedStorage.RemoteEvent.OnClientEvent:Connect(function(gui)
	local frame = workspace.Folder.kabob.BillboardGui.Frame
	frame.Size = UDim2.fromOffset(frame.AbsoluteSize.X / 2, frame.AbsoluteSize.Y)
end)
