How to Write an If - Else Statement in Adobe Flash ActionScript 3.0

What would any programming language without the ability to test a condition and then act upon that test. Adobe's Flash ActionScript 3.0 programming language gives that ability with the the IF-ELSE statement.

Here is how you write an IF-ELSE statement in Adobe's Flash ActionScript 3.0 programming language.

Difficulty: Easy

Instructions

Things You'll Need:

• Adobe Flash CS4

1. The IF-ELSE statment is read as "if some condition is true then do something, if the condition is not true, then do something else". The first line of the IF-ELSE statement is written as:
   
   if (some condition) {
   
   That's "if" open parenthesis, followed by the condition you want to test, a closed parenthesis, then an opening curly brace which signifies the code after that brace is to be executed if the "some condition" is true.

2. The next series of lines is the code to be executed if the condition is true. It can be a series of lines of code, a call to a function and so on. So you code now looks like:
   if (some condition) {
   Some code
   }
   
   When you are finished with the code that you want executed if the condition is true you simply end it with a closed curly brace as shown above.

3. Finally, although not required, we add in our ELSE statement. This gets exceuted if the condition in the steps above is false.
   
   else {
   execute this code if condition is not true
   }
   
   Just like the first part you open your code block with an open curly brace, put in your code and close it with a closed curly brace. So you final code looks like this:
   
   if (some condition) {
   code
   }
   else {
   more code
   }
