Changing Movie Clip Position And Appearance; Dragging Movie Clips - MACROMEDIA FLASH MX 2004 - ACTIONSCRIPT Reference Manual

Changing movie clip position and appearance

To change the properties of a movie clip as it plays, write a statement that assigns a value to a
property or use the
instance to 45:
mc
mc._rotation = 45;
This is equivalent to the following code, which uses the
setProperty("mc", _rotation, 45);
Some properties, called read-only properties, have values that you can read but not set. (These
properties are specified as read-only in their ActionScript Dictionary entries.) The following are
read-only properties:
,
_totalframes
You can write statements to set any property that is not read-only. The following statement sets
the property of the movie clip instance
_alpha
car.wheel._alpha = 50;
In addition, you can write statements that get the value of a movie clip property. For example, the
following statement gets the value of the
sets the property of the
_x
onClipEvent(enterFrame){
customCursor._x = _root._xmouse;
}
This is equivalent to the following code, which uses the
onClipEvent(enterFrame){
customCursor._x = getProperty(_root, _xmouse);
}
The , ,
_x _y _rotation
are affected by transformations on the movie clip's parent, and transform the movie clip and any
of the clip's children. The
properties are global; they belong only to the level 0 main Timeline. All other properties belong to
each movie clip or loaded level.
