Slider doesn't work

[Guest_2000123145]

I have a slider that for some reason bottoms out at 0.025 and tops out at 0.975 (Position.X.Scale)
I’d like it to go all the way to 0 and 1. Not sure how to do it, I’m here for help and suggestions.

Slider.rbxl (61.7 KB) ← here is a simplified file with only the problematic item

Press play, it should print the slider’s position whenever you drag it.

Thanks in advance!

That’s because slider position is never reaches expected limits 0 and 1.
And this is tied to its scale.
The value must be mapped.
This works for me:

Handle:GetPropertyChangedSignal("Position"):Connect(function()
	local sliderPosition = Handle.Position.X.Scale
	local slider_inflation = Handle.AnchorPoint.X * Handle.Size.X.Scale
	local slider_len = 1 - 2 * slider_inflation
	sliderPosition = (sliderPosition - slider_inflation) / slider_len 
	sliderPosition = math.round( sliderPosition * num ) / num
	print(sliderPosition)
end)

With this code you can change slider’s width and it still works.

Thank you for this code, but it’s not what I was looking for. I’m looking for the slider to be able to reach the expected limits, not a workaround. Thanks again :D

The handle can’t fully reach the edges because of its own Size. The Position.X.Scale is relative to the top-left of the handle, not the center of the slider track. To hit 0 to 1 you need to account for the handle size:

local Handle = script.Parent.SliderContainer.Handle
local Track = script.Parent.SliderContainer
local preciseness = 4
local num = 10^preciseness

Handle:GetPropertyChangedSignal("Position"):Connect(function()
	local trackWidth = Track.AbsoluteSize.X
	local handleWidth = Handle.AbsoluteSize.X
	local minScale = 0
	local maxScale = 1

	local posX = Handle.Position.X.Scale
	local minOffset = handleWidth / 2 / trackWidth
	local maxOffset = 1 - minOffset

	local sliderValue = (posX - minOffset) / (maxOffset - minOffset)
	sliderValue = math.clamp(sliderValue, 0, 1)
	sliderValue = math.round(sliderValue * num) / num

	print(sliderValue)
end)

af_2048 understand this and that is not a workaround. In fact he’s has even accounted for different widths..

Good to know.

Sorry I didn’t specify, but I was more or less looking for a solution without code. If it doesn’t arise, I will mark af_2048’s post as the solution :D

No code.. still mark his as the solution.
