Check when PrismaticConstraint stops moving

[Dogntbad (Dognt)]

I have a moving platform that plays a sound the moment it begins moving with a Prismatic Constraint

I want that sound to stop moving the moment it reaches it finishes reaching its target position

I have tried:

• Getting the position it moves to and checking when it reaches that position using
  repeat task.wait() until example_platform.Position == super_specific_position
  However, that doesnt work because it changes ever so slightly by like 10 decimal spaces

• Using the starting position subtracted by an empty Vector3 and getting the magnitude of it
  It never worked, or maybe I was doing it wrong??

If there is a slight mistake Im doing or if I should approach this completely different, please tell.
Any help is appreciated.

Try task.wait(the time value in the constraint)
Then the code you want

Put a script in the part that is moving, and paste this:

local run = game:GetService("RunService")
local value = script.Value
local point = game.Workspace.Point -- replace "Point" with the name of the certain point you're mentioning

run.Heartbeat:Connect(function()
	value.Value = math.floor(script.Parent.AssemblyLinearVelocity.Magnitude*1)
	if value >= 0 then
		script.Parent.Sound:Play()
	end
end)

point.Touched:Connect(function(part)
	if part == script.Parent then
		sound.Stop()
	end
end)

MAKE SURE TO ADD A NUMBERVALUE IN THE SCRIPT

Thank you so much!

I’ll be honest, I didn’t fully implement your entire solution, but the part that helped me out the most was
math.floor(script.Parent.AssemblyLinearVelocity.Magnitude*1)

Again, thank you so much for the help. Also, sorry for the delay.
I hope you have a great day and so on.
