Explanation of destroy() please?

So;

:Destroy() Is a method you can use on any instance inside roblox, it's pretty self explanatory, it destroys the object. Once you destroy an object, you can not get it back, unlike the method :Remove(), which I'll explain later.

How to use :Destroy()...

So say you had a brick inside the workspace, named Part1. You could destroy the part like this:

workspace.Part1:Destroy()

Pretty simple right? Except you can't do something like this:

local s = workspace.Part1
s:Destroy()
s.Parent = workspace

That would throw an error at you. You could, however, do that with :Remove().

:Remove() is a method much like :Destroy(), except what remove does is parents the object to nil. nil is a word that basically means nothing, as in it parents the object to nothing, so we could re-parent it later.

Here's how you can use remove:

workspace.Part1:Remove()

So, just like destroy. Here's how you can get the object back into your game after you remove it:

local s = workspace.Part1
s:Remove()
wait(1)
s.Parent = workspace

That would remove the object from the workspace, wait 1 second, then make it come back, as if cloning it.

I hope I did alright at explaining this =) +1 my rep if I did.
