Variables and functions are used to help you shorten your code and create easy shortcuts to executing scripts.

Variables: A variable is a name, given by a programmer, to represent a piece of data. This name is then used to refer to that piece of data at any time in the script.

Example
Bob wants to change the color of a brick multiple times. His code is as follows.

Code:

game.Workspace.Bluebrick.BrickColor = BrickColor.new("Cyan") wait(5) game.Workspace.Bluebrick.BrickColor = BrickColor.new("Really Red") wait(5) game.Workspace.Bluebrick.BrickColor = BrickColor.new("Black") wait(5) game.Workspace.Bluebrick.BrickColor = BrickColor.new("White")

Bob is tired of writing "game.Workspace.Bluebrick.BrickColor" over and over. He wants a way to shorten the code.

Bob could assign a variable to "game.Workspace.Bluebrick.BrickColor" so that he doesn't need to write that part of the code again and again.

Bob's code shortened by a variable would look like the following

Code:

Myfirstvar = game.Workspace.Bluebrick Myfirstvar.BrickColor = BrickColor.new("Cyan") wait(5) Myfirstvar.BrickColor = BrickColor.new("Really Red") wait(5) Myfirstvar.BrickColor = BrickColor.new("Black") wait(5) Myfirstvar.BrickColor = BrickColor.new("White")

The "Myfirstvar = game.Workspace.Bluebrick" part of the code sets the variable. The Variables are CASE SENSATIVE, meaning, if your variable was "Hello" you could not write "hello" or "HELLO".

So yuo can also make it x = game.Workspace.Bluebrick...right?

ok cool

Please note that if you save a Value, when reading the Value, it will come up with the original value that was there when you created the variable.

You can set mutiple variables in a single line also. Like this

local (a, b, c = c, b a)
print(a, b, c)

Nice, simple tutorial! Good job.
