Statements, Expressions, & Operators

The entire block of text in the Actions panel is a Script, where each line of code is a statement. Statements are sentences of Code.

Expressions in Flash are statements that are evaluated (that will give you some value or return a value).
ex. mymovieclip._alpha=50

Operators perform specific (usually math) operations
ex.
+(plus),-(minus),=(equals), * (multiply), < (less than),
> (greater than), <= (less than or equal to).

note: You check things like equality with a different operator than you assign equality.

setting and assignment:

Funny=true


Checking equality:

if (Funny == true){
then proceed
}

Notice the double == sign. This checks to see if a variable is equal to a value or a condition. The = sign is use to set variables equal to a value

Blocks

A block is a group of statements contained within braces {}
An opening { and a closing } are necessary to for each block of code. A block is like a paragraph of a sentence. If these are not written in correctly, your script will not work. Also note semicolons between statements.

example:

on (press) {
myClip._alpha=20;
myClip2._x=300;
}
