It still remains with the math.ceil(), which rounds numbers to the highest number possible.
I updated the comment with the newer version that uses math.round().

Still not precise if i put 500 sometimes it give me 499 or 501

Script i use :

That’s because whenever Lerping it doesn’t linearnly interpolate until the requested number, or just takes a delay to reach that number. I don’t think I got anything to do with it. Try using TweenService.

#55

how do i use tweenservice in that

#56

and when i change the temperature value it reduce it i don’t want the script to change it

#57

Delete the ‘CurrentNumber’ value.
Insert a new Vector3 value, named it ‘CurrentNumber’, and leave it there.
Test this code and it should work:

local tweenService = (game:GetService("TweenService"));
local runService = (game:GetService("RunService"));

local numberGoal = Instance.new("NumberValue");
numberGoal.Parent = script.Parent
numberGoal.Name = "NumberGoal"

local currentNumber = (script.Parent:WaitForChild("CurrentNumber"));
function TextUpdate()
	tweenService:Create(currentNumber, TweenInfo.new(1), {Value = Vector3.new(numberGoal.Value, 0, 0)}):Play()
end;

numberGoal:GetPropertyChangedSignal("Value"):Connect(TextUpdate)

function Heartbeat(dt)
	script.Parent.Text = math.round(tostring(currentNumber.Value.X))
end;

runService.Heartbeat:Connect(Heartbeat)

Edit: Doesn’t necessarily have to be a Vector3 value, you can use a normal NumberValue, and then tween it’s value. I have no clue why I used Vector3.

If you still wanted to use lerping youd just have to change the math for the alpha value a bit

Instead of doing dt * SPEED, you could do

math.clamp((dt * SPEED)/math.abs(numberGoal.Value - currentNumber.Value),0,1)

It gives that

Delete the existing CurrentNumber, again.
Reinsert a NumberValue and named it ‘CurrentNumber’.
And use this:

local tweenService = (game:GetService("TweenService"));
local runService = (game:GetService("RunService"));

local numberGoal = Instance.new("NumberValue");
numberGoal.Parent = script.Parent
numberGoal.Name = "NumberGoal"

local currentNumber = (script.Parent:WaitForChild("CurrentNumber"));
function TextUpdate()
	tweenService:Create(currentNumber, TweenInfo.new(1), {Value = numberGoal.Value}):Play()
end;

numberGoal:GetPropertyChangedSignal("Value"):Connect(TextUpdate)

function Heartbeat(dt)
	script.Parent.Text = math.round(tostring(currentNumber.Value))
end;

runService.Heartbeat:Connect(Heartbeat)

It worked fine for me when testing, no matter for what number.

This may interest you, otherwise lerping I guess.

#62

Okay, it works, but now how do i link the script with my temperature value ?

#63

The script should remain where it is.
You have to change the ‘NumberGoal’ value through other scripts (on the Server), and the script will do it’s work.

#64

Yes but it’s the script that create NumberGoal so i don’t know how to change the value

#65

You’d just reference.

workspace[...][...][...].NumberGoal.Value = ?
#66

I did that but when i change the temperature value the text on the screen don’t animate

#67

it only animate when i change number goal

#68

Wait, i managed to make it work

#69

Yes it work now thank you so much
