actionscript 3 - AS3: Scale movieclip at another movieclips position? -


i'm trying scale base image based on movieclip's x , y position? base image image mc.

infoiconcompfit.addeventlistener(mouseevent.roll_over, zoomincompfit); infoiconcompfit.addeventlistener(mouseevent.roll_out, zoomoutcompfit);  function zoomincompfit(event:mouseevent):void {    tweenlite.to(baseimage, 1, {scalex:2, scaley:2}); }  function zoomoutcompfit(event:mouseevent):void {    tweenlite.to(baseimage, 1, {scalex:1, scaley:1}); }

what mean is; possible scale movieclip @ movieclip's x , y position on stage? want base movieclip scale (zoom in) @ position of movieclip on mouse roll_over zoom out on mouse roll_out.

i zooms in , out on handlers, how zoom @ position relative other mc?

yes can. need write code , have in mind transformation pivot of objects.

/**          * calculate position , dimensions of image zoom.          * @param   img - image animate, need have transformation pivot in top left corner!          * @param   point - point zoom in (or null if zoom out) new center of image          * @param   scale - scale in zoom in          * @param   viewwidth - container width          * @param   viewheight - container height          * @return  object tween engine parameters animate          */         private function centeron(img:displayobject, point:point=null, scale:number=2, viewwidth:number=300, viewheight:number=200):object         {             var r:object;             var mm:matrix = img.transform.matrix;             img.transform.matrix = new matrix();              if (point == null) { // oryginal size                 r = { x: 0, y: 0, width: img.width, height: img.height };             }else { // zoom                 img.scalex = img.scaley = scale;                 point.x *= scale;                 point.y *= scale;                 img.x = -point.x + viewwidth / 2;                 img.y = -point.y + viewheight / 2;                 r = { x: img.x, y: img.y, width: img.width, height: img.height };             }             img.transform.matrix = mm;             return r;         }

use example:

tweenlite.to(baseimage, 1, centeron(baseimg, new point(100, 150))); //zoom in tweenlite.to(baseimage, 1, centeron(baseimg)); //zoom out centeron(img, new point(200, 135), 4, stage.stagewidth, stage.stageheight); // fit stage size

remember display object not masked , (zoom near borders) see scene under it!

ps. code tested.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
