How does generating random numbers in this script work?

while wait(math.random(5)) do
	script.Parent:Play()
end

OK.

This is my script I have in my game. Basically what it is suppose to do is randomly play thunder in my game. I just don't want the thunder to be at the exact same time each time so I tried doing math.random and I got everything figured out, but how does the parentheses work?

I assumed if you put a number in the parentheses it'll choose a random number for 1-whatever number you chose. In my case I have five so thunder would play 1-5 seconds each time , right?

To get better random numbers, I would recommend using a seed value derived from os time, and then taking off a few of the values - here is a function I use to consistently get random numbers from Lua - otherwise you may end up getting the same numbers all the time, in the same order, when you call the math.random function.

local function randomnum (minimum,maximum)
		
			   
			  math.randomseed(os.time())
			
			local r = math.random(minimum,maximum)
			 r = math.random(minimum,maximum)
			 r = math.random(minimum,maximum)
			
			return r

	end

Yep! That should work the way you want it to! However if it doesn't then try this:

while true do
wait(math.random(5)) do
script.Parent:Play()
end
