What does the term local do? I really want to know.
What does the term local mean?

Do you mean "local" in general, or the actual keyword "local" in Lua? ScriptGuider 5640 — 8y

This is late, but local is a variable.. Basically, if I were to do "local i = game.Workspace", Instead of me having to put "game.Workspace", I just have to put "i". crywink 419 — 7y

local sets the variable so that it's only available in the current scope.
in these examples, world is just the name of the function, it could be anything
1 | local a = "Hello," |
2 |
3 | function world() |
4 | local b= "world!" |
5 | end |
6 | world() |
7 |
8 | print(a,b) --> "Attempt to index a nil value (b)" |
This happens because b is now only available inside of the function (The scope) where it was created.
The following works because the value of b is created outside of the function world(), so it can be accesed outside of it.
1 | local a = "Hello," |
2 | local b |
3 |
4 | function world() |
5 | b= "world!" |
6 | end |
7 | world() |
8 |
9 | print(a,b) --> "Hello, world!" |
This works too because b isn't local.
1 | local a = "Hello," |
2 |
3 | function world() |
4 | b= "world!" |
5 | end |
6 | world() |
7 |
8 | print(a,b) --> "Hello, world!" |
Another thing to note is that local variables are indexed a bit faster (barely noticable though)

the term > local means the start of a variable, for example,
1 | local Block = game.Workspace.Part |
2 |
3 | Block.Transparency = 1 |

It doesn't. Read my answer so you know what it actualy does. You don't HAVE to put local infront of everything, but its highly recommended. RubenKan 3615 — 8y
