First off we have to understand what a variable is.
A variable is a storage location that you can use to declare a data type and assign that data type a corresponding value. This means that if you plan to use a reference to something repeatedly, you can just name that value and declare it as a variable to be called upon throughout your script(s).
So what makes up a variable?
Variables consist of 4 parts: The Reference, Data Type, Name, and Value. The fourth one (Value), doesn’t have to be declared in your script and is thus “optional”. Every variable has a default value though.
[Definitions]
“Public” variables are visible to other scripts and “Private” variables are not.
“Int” stands for “Integer” and represents a whole number.
“Float” represents a number that may contain a decimal value.
“Bool” stands for “Boolean” and is a true or false value.
“String” is a line of text or (a string of characters).
[ADVANCED TIP]
It is not good practice to directly change variables from other scripts as it can bog down your program. To do this properly you should call a separate method from within the script that contains the variable and change it in there.
