Variables in AS 3.0

A variable is a "container" represented by a name that holds information. That information can be later changed or retreived through the code using the variable-name.

You need to declare a variable the first time you use it including word var, the name of the variable, the data type and initial value.

var	myVariable	:	int	=	8	;

var	name	:	data type	=	initial value	;

The name of the variable should be one word, easy to remember and identify when debugging code. It should be written all lowercase, with no special characters.

To change the value: myVariable = (myVariable +1) also like that: myVariable+=1

To retreive the current value of the variable: trace (myVariable)

Basic Data Types

The data type is included in the declaration and it defines what kind of data can the be stored in it.

INTEGER

Stores numbers, positive or negative. lt is the fastest variable type to get processed so it should always be your first choice (int). It does not support floating numbers (1.55)

var myrule : int =-4 ;

UINT

Unsigned integer. Stores only positive numbers (uint)

var mygrade : uint =4 ;

NUMBER

Stores fractional values, written as floating point numbers (Number). It works much slower than an Integer.

var mygrade : Number =7.8 ;

STRING

Stores apiece of text (a combination of letters with spaces).The text should be written in quotes.

var salutation :String ="hello friends" ;

BOOLEAN

Stores 2 opposite values: True or False

var my : Boolean = false ;

(not defined)

A variable with no data type in the declaration becomes a "versatile object type" that can hold any of the previous values.

ARRAYS and
OBJECTS

Those are variables that holds more than 1 value. They are very useful for structuring game data.

var character1 : Object ={ charType: "Heroine" , charLevel: 6 , charHealth: 0.8 } ;
