Movie clip symbols in the Library

Movieclip symbols can be referenced by actionscripting, they can contain animation or a series of sprites (depending if you ask the timeline to play or to stop) and new instances of a movieclip can be created through code.

(for a movieclip called BlueCircle in the AS Linkage)*

var	newCircle	: BlueCircle	=	new BlueCircle ();

this.	addChild	(newCircle);

Notice that we are creating a variable containing our new instance of the movieclip so the code knows the new instance of BlueCircle as newCircle.
* to name a movieclip for an exteral AS file, or to generate new instances throug code, you need to click on the small button on the right of the Library panel, go to "Properties" (symbol Properties) and click on the advanced button at the bottom, in the Class textfield enter the name of the movieclip.

Now we can define the properties of this object, like:
(In the window below you can see a list of all the properties that we can refer to)

newCircle	.	x	=	225	Horizotal size in pixels

newCircle	.	y	=	5	Vertical size in pixels

newCircle	.	scaleX	=	0.5	Horizontal scale size in pixels

newCircle	.	scaleY	=	3	Horizontal scale size in pixels

Category	ActionScripting 3	Description	Example
position	x	Horizontal coordinate in pixels, begining from the upper left corner of the Stage (0,0)	cat_mc . x =150
position	y	Vertical coordinate in pixels, begining from the upper left corner of the Stage (0,0)	cat_mc . y =20
size	scaleX	Horizontal scale, 1=100 percent	cat_mc . scaleX =0.5 Half of the original width
	scaleY	Vertical scale, 1=100 percent	cat_mc . scaleY =3 Tripples the original height
	width	Horizontal dimension, in pixels	cat_mc . width =26
	height	Vertical dimension, in pixels	cat_mc . width =42
orientation	rotation	Rotation angle, in degrees, from the object's original orientation. Positive values represent clockwise; negative values represent counterclockwise.	car_mc . rotation =45
visibility	alpha	Transparency is measured form 0 to 1, 0 been fully transparent and 1 fully opaque.	car_mc . alpha =0.7
visibility	visible	True or false to spacify whether or not the object is visble.When set to false, the object is diabled, that is, it cannot be clicked.	car_mc. visible = false
