Moving platform not working

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? i want a working moving platform that moves and comes back to its position

  2. What is the issue?
    it first go really far then after that it does the loop. how do i fix to only do the loop

local part = script.Parent 

local dir = 1

local max_val = 25
local min_val = -25 

local wait_time = 0.1

while true do
	part.Position = part.Position + Vector3.new(1*dir,0,0)
	wait(wait_time)

	if (part.Position.X > max_val) then 
		dir = -1
	end

	if (part.Position.X < min_val) then
		dir = 1
	end
end

That’s because max_value and min_value aren’t relative to the part default position, therefore the part will only work as expected if it’s starting X axis is 0. Instead 25 should be the position offset:

local max_value = part.Position.X+25
local min_value = part.Position.X-25

Also there’s no need to overcomplicate your code, TweenService can help you smoothly move the part while reducing any lag that may be caused due to the loop and it’s much easier to implement with useful configurations:

local TweenService = game:GetService("TweenService")

local part = script.Parent 

--tween configuration
local info = TweenInfo.new(
	1, --time before the tween finishes
	Enum.EasingStyle.Linear, --Linear easing style remains constant
	Enum.EasingDirection.InOut, --doesn't make a difference because we're using linear 
	-1, --amount of repeats, -1 makes the repeats infinite  
	true --reverses 
)

local offset = 25 --part offset 

part.Position -= Vector3.new(offset, 0, 0)
--creating the tween, offset*2 because we subtracted the offset before
local tween = TweenService:Create(part, info, {Position = Vector3.new(part.Position.X+offset*2, part.Position.Y, part.Position.Z)}) 
tween:Play() --playing the tween

local part = script.Parent 
local part_x_position = part.Position.X
local dir = 1
local wait_time = 0.1

while true do
	part.Position += Vector3.new(1*dir, 0, 0)
	task.wait(wait_time)

	if (part.Position.X > part_x_position + 25) then 
		dir = -1
	end

	if (part.Position.X < part_x_position - 25) then
		dir = 1
	end
end
