How to scale gui on only the x axis?

Help and Feedback Scripting Support

#1

I have these bars that scale along with the player’s stamina and health, and of course, they should only get bigger and smaller on the x-axis.
script.Parent.Health.Progress.Size = UDim2.new(math.floor(Character.Humanoid.Health)/100, 0, 1, 0)
Why is this line of code not working?

#2

Full script or any error please? It might not be that code, but whatever function/loop is related to it isn’t running it.
PS, UDim2.fromScale() is a thing.

There are no errors, I’ll try using udim2.fromscale now

#5

To me, it seems fine. Try putting a print() to see if the function itself is even being run. Might be wiser to use Humanoid.HealthChanged?
UDim2.fromScale is not the solution by the way, it’s just a neater more compact touch that I recommend.
Did you test taking damage first?
