Class Naming Conventions in Flash ActionScript



The standard naming convention for variables in Flash is Small Camel Case. When naming classes, the convention is similar except the Class Name should start with a capital letter. This convention is called BigCamelCase.

For more information on Small Camel Case, see topic, Variables. In this example we will create a Class by exporting a library Movie Symbol for ActionScript.

Naming a Class

When naming a Class or Library asset using BigCamelCase try to observe these rules:

Capitalize the first letter

No spaces

Use numbers and/or letters

Avoid using any special characters

Character exceptions are ($, _)

Don't use any reserved words (they appear in blue)

Never start a Class with a number

Assign a name that makes sense

Controlling Library Symbols with ActionScript
