How to make a block move up 50 studs, wait 1 second, move down 50 studs, repeat? [closed]

Ok, so this is my first time helping someone but I recommend using TweenService Im not sure how much this will affect performance but ill give u an example below(in case u wanna use it)

local TweenService = game:GetService("TweenService") 

local part = WHATEVER PART

local goal = {}
goal.CFrame = Part.CFrame * CFrame.new(0, 50, 0)

local tweenInfo = TweenInfo.new(
    5, -- Time
    Enum.EasingStyle.Quart, -- EasingStyle
    Enum.EasingDirection.Out, -- EasingDirection
    -1, -- RepeatCount (when less than zero the tween will loop indefinitely)
    true, -- Reverses (tween will reverse once reaching it's goal)
    1 -- DelayTime
)

local tween = TweenService:Create(part, tweenInfo, goal)

tween:Play()

I haven't tested this out so I 110% doubt it would work but its just to give u an idea if you want, u can check out some examples or tutorials on youtube or go read up on TweenService at

https://developer.roblox.com/en-us/api-reference/class/TweenService

so uhh this is my first post on this website so like later today ill edit it if I realise I can make it more appealing or if its breaking any rules

hope this helped

You might want to use CFrame.

local platform = script.Parent --Set this to the part you want to move up and down.

while true do --While loop repeats it
    for i = 0, 100 do
        platform.CFrame = platform.CFrame*CFrame.new(0, .5, 0) --Moves the platform up half a stud 100 times (total 50 studs)
        wait(.001)
    end
    for i = 0, 100 do
        platform.CFrame = platform.CFrame*CFrame.new(0, -.5, 0) --Moves the platform down half a stud 100 times (total 50 studs)
        wait(.001)
    end
    wait(.1) --Prevents while loop from crashing the game.
end
