How to make a script repeat itself over and over again?

Hello!

Use a while loop.

while true do
    print("I'm cool")
    wait()
end

Make sure to add a wait() in there or studio will crash!

This while loop will loop forever in a script as long as the variable condition is true

local condition = true
while condition do 
wait()
end

Additionally you can head over to https://www.robloxdev.com/articles/Roblox-Coding-Basics-Loops to learn more about looping and how it works

while true do is the easiest loop you can have,

while true do
    elite hacker code here
end

This depends if you want it too go on forever or a set amount of time.

If you would like it to repeat a certain amount of times do this.

for i = 0,100 do
--Code here
end

Change '100' too whatever number you want.

If you would like it to repeat forever do this

while true do
wait()--make sure you have this. Without it. It will crash the Server/Client.
end
