Property Names

[grande]

Hi all,

So what's the difference between _width and width? _height and height? _alpha and alpha?

Anyone know? Why do some have underscores and others don't?

The underscore naming convention was not logical, so that [tt]_width[/tt] has been replaced with [tt]width[/tt] in AS3.

So, AS2 = _
AS3 = no _

There are no properties with underscore in AS3 (as far as I'm aware). In AS1/2, some property has it, some don't. [tt]MovieClip._width[/tt] has it, but [tt]MovieClip.enabled[/tt] doesn't. [tt]MovieClip._x[/tt] has it, but [tt]UIObject.x[/tt] doesn't. It's not consistent - that's why all underscores are removed in AS3.
