scale
Syntax
member(

).scale
the scale of member
whichCastMember
sprite(
whichSprite
).scale
the scale of sprite
whichSprite
Description
Cast member property and sprite property; controls the scaling of a QuickTime, vector shape, or Flash movie sprite.
For QuickTime, this property does not scale the sprite's bounding rectangle or the sprite's controller. Instead, it scales the image around the image's center point within the bounding rectangle. The scaling is specified as a Director list containing two percentages stored as float-point values:
[xPercent
,yPercent
]
The xPercent
parameter specifies the amount of horizontal scaling; the yPercent
parameter specifies vertical scaling.
When the sprite's crop
property is set to TRUE
, the scale
property can be used to simulate zooming within the sprite's bounding rectangle. When the sprite's crop
property is set to FALSE
, the scale
property is ignored.
This property can be tested and set. The default value is [1.0000,1.0000].
For Flash movie or vector shape cast members, the scale is a floating-point value. The movie is scaled from its origin point, as specified by its originMode
property.
Note: This property must be set to the default value if the scaleMode property is set to #autoSize; otherwise the sprite does not display correctly.
Example
This sprite script keeps the playback head looping in the current frame while the QuickTime sprite in channel 5 is scaled down in 5% increments. When the sprite is no longer visible (because its horizontal scale value is 0% or less), the playback head continues to the next frame.
on exitFrame me scaleFactor = sprite(spriteNum).scale[1] currentMemberNum = sprite(spriteNum).memberNum if member(currentMemberNum).crop = FALSE then member(currentMemberNum).crop = TRUE end if if scaleFactor > 0 then scaleFactor = scaleFactor - 5 sprite(spriteNum).scale = [scaleFactor, scaleFactor] go the frame end if end
Example
This handler accepts a reference to a Flash movie sprite as a parameter, reduces the movie's scale to 0% (so it disappears), and then scales it up again in 5% increments until it is full size (100%) again.
on scaleMovie whichSprite sprite(whichSprite).scale = 0 updatestage repeat with i = 1 to 20 sprite(whichSprite).scale = i * 5 updatestage end repeat end
