I know this is really stupid but.. How do I make a choppable tree. That regrows?

I am making a game like Old School Runescape on Roblox. I am in need of help of making a tree when you click it with the axe equipped it will play a animation for a time limit like 20 -15 seconds. When the time limit is done it will give you a log. (That you can sell for coins. I promise this isn't a simulator) You could (It will be really helpful) To make it that the tree changes transparency when chopped and (regrows every 20 seconds) I don't have a script because I don't know how to do it. I tried tutorials but they we either outdated or Doesn't have the thing I need. If you see this and know how it will be very helpful! :)

(Sorry if there are grammar mistakes)

So I'm assuming that you have all the scripts besides the respawn one? All I can understand is that you'd need the tree to run as a Humanoid. Hide the health bar on Humanoid, then write something like this:

if z.Tree.Health == 0 then
		z:Remove()
		wait(20)
