As3 get WIDTH and HEIGHT of scaled / resized – movieClip / mc

actionscript-3flashheightscalewidth

I am scaling a movieClip often and need to place it on the screen in certain places according to its size.

Once scaled, how can I get the WIDTH and HEIGHT of a movie clip?

trace(my_mc.width); /// would equal 333

/// This code makes my movie clip fit in the correct proportions. 
my_mc.height = stage.stageHeight;
my_mc.scaleX = my_mc.scaleY;

/// Its been resized!
trace(my_mc.width); /// STILL equals 333

Any ideas how to get new width and height?

You're probably experiencing stage scaling issues.

If you're dependent on stage size, set:

import flash.display.StageAlign;
import flash.display.StageScaleMode;

stage.scaleMode = StageScaleMode.NO_SCALE;
stage.align = StageAlign.TOP_LEFT;

Your provided example doesn't encapsulate the problem. It works as expected.

size scale

Also possible is timing of your trace statements, if you're doing frame-based animation. Perhaps you're viewing an artifact of size instead of in line with the lifecycle you expect.

Actionscript – Change MovieClip width along with dynamic text field’s size inside it

You need to set myClip.myText.autoSize = TextFieldAutoSize.LEFT, else the textfield will not expand with the text. You do not need to set the width of the movieclip, its size depends on its content. Setting the size will only stretch the content (but for textfields this only works when the text is embedded).

Css – Setting width/height as percentage minus pixels

You can use calc:

height: calc(100% - 18px);

Note that some old browsers don't support the CSS3 calc() function, so implementing the vendor-specific versions of the function may be required:

/* Firefox */
height: -moz-calc(100% - 18px);
/* WebKit */
height: -webkit-calc(100% - 18px);
/* Opera */
height: -o-calc(100% - 18px);
/* Standard */
height: calc(100% - 18px);
