Loop won't continue untill function is over?

I have "while true do" loop which calls a function every 0.1 seconds

while true do
	wait(0.1)
	func() --function
end

And function have 1 second delay:

function func()
	wait(1)
	print("Done")
end

The problem is - loop won't continue untill function will be over, and that means function will run every 1 second instead of 0.1. How do i fix it?

In order to have your 'func' function fire every .1 seconds, you will want to use the spawn function. spawn() is much like coroutine.wrap(function() end)(), which is the equivalent to coroutine.resume(coroutine.create(function() end)) except you can do a few more things with coroutines. Spawn and Coroutines are kind of like threads someone can probably explain this better than I can, to put it in simple terms, it is like your function is running in another script.

Since you already defined your function you do not need to copy and paste the function into the spawn function.

function func()
	wait(1)
	print("Done")
end

while true do
	wait(0.1)
	spawn(func) --Now if you did want to copy and paste the code from above into here, it would be like below
	--spawn(function()
	--wait(1)
	--print("Done")
	--end)
end

Coroutines, what are you trying to make? I would make the function into a coroutine because scripts read like a book and when you call a function the function is read same. Coroutine's are the only way to run a function multiple times in a same sccript
