Flash :: Dynamically Change The Width / Position Of A Timeline-animated Mask?
Jan 27, 2010
I've got a movieclip with two layers - a background movieclip, and above that, a mask movieclip (as you might guess, this layer is masking the first). Due to design necessity, the mask is animated on the timeline across 60 frames.The problem arises when I use an Event.RESIZE listener to change the width of the parent movieclip when the browser window is resized. Any code to reference the mask, i.e
Is there a way to mask a movie clip in a way that alters the width and height of the object? I have a child movie clip that is larger in width so I'm having issues manipulating the width, height and coordinates proportionally of the parent movie clip.
Am I completely hallucinating or what ? That's several years I'm working with Flash, and today, i want to do the simplest animation ever, and it just doesn't work....I want to mask an animated clip with an animated mask (a shape animation), but every time the mask arrives at a keyframe, the clip restarts to the frame 1 !!I added a piece of code to see at which keyframe it is blocked, and at every mask keyframe, the code says 'TypeError: Error #1009: null property..
I have simple image gallery, where images are placed one next to another and the mask is revealing only one of them. Now I want to tween position of the images, but when I do that the mask is "traveling" alongside with the images..
I've been trying to dynamically change some text for a titlebar that is behind a mask However, I find that when I change the text of the dynamic text field (whose containing movieclip is masked by a graphic), the text no longer appears at all. When i remove the masking, the text changes properly when asked, but when it it masked, the text does not show at all.
Can we change the width of the datagrid column dynamically by clicking on the border of the column in order to display the complete string which is too long to be displayed and needs to be scrolled ? If so, How ?
Also, how can we ensure that the column width changes dynamically based on the number of characters / length of string; since many a times the data is too long to be displayed. Can we set the column width to take the length of data into consideration before displaying onto the datagrid ?
Already I have one video player and it's width and height are set as 450 and 370 respectively. It's set by statically on its property field. Now I want to change the width and height of video component according to the specified value. Also the control box should be scale accordingly. But when i tried to change the video component's width and height while loading, it's not getting changed.
I am using a singleton class (popup, which means it doesn't forget the last used variables) which contains a datagrid. I am making various columns visible/invisible, setting the widths and headers in accordance to data received from a database call. Everything works fine except that when I put the breakpoints before and after the point where I change width of columns, I do not see the change in width of datagrid at all! Instead I see some values totally out of sync as widths of datagrid column! However, since it is a singleton class, the next time I call this popup, I see widths which I did set up in last call.
I must be messing up in calling the setWidth() function (which is my custom function which changes the width of datagrid in action script). What should be the point where I should call this function? I tried in creationComplete, show and in the setter of dataprovider.
Being a complete beginner in AS3 (and coding in general), I'm trying to do the opposite of what's seen in this swf (I'd like to have the spinning logo filled with the background colors): [URL]. I was thinking of a very simple way with this kind of code:
ActionScript Code: var i:int=0; var logo_vector:MovieClip=new LOGO_VECTOR(); logo_vector.x=192; logo_vector.y=140; //logo_vector.cacheAsBitmap=true; [Code] .....
But while a logo_vector.rotation makes the logo spin around the Z axis and works, the rotationX gives a black screen. AS I could see the logo appearing onone frame, I thought that caching as bimtap on each frame would do the trick but it doesn't. I tried to put the logo into another movieclip but still no chance.
I thought about drawing the logo into a new bitmap as well, and then do a work on the pixels directly to have an opaqe background and the black logo transparent but there again, I can't get the logo position to refresh properly (and can't get it to be in the center of the bitmap).
I tried to copy the sprite into a bitmap: var masque:BitmapData=new BitmapData(384, 282,true,0x00ffffff); var masque_bmp:Bitmap=new Bitmap(masque); and Masque.draw (logo_vector);
In the Enter Frame function but I'm getting an empty rectangle and if not used as mask, the graphics are not refreshed)?
I have a curved graphic that I need masked, but the mask will slowly unveil the graphic below. I'm tweening the mask on the timeline since the graphic has a pretty complex shape (a bunch of curveTo's would take forever).If I apply a shape tween to the mask it doesn't tween on curves that well unless I place a keyframe at every two frames and adjust the shape. Does anyone know if there is a better solution?
I'm attempting a neat little effect where I've got a fellow walking (already drawn and animated) and I'm using him as a mask over the top of a simple colored rectangle - the idea being, by changing the color of the rectangle, I can have a walking man with color effects happening. At this stage the square is just green, because the mask is not quite working correctly. The edges of the animated mask glitch up and don't work as expected
I've got this interactive storybook that loads each page from separate swf files into a movie clip. The movie clip is masked, and with every turn of the page, the mask changes shape so it looks like the pages are covering up the content. Once the page turn is complete, we're supposed to be left with two fresh pages so we can load more content.
Here's my dilemma: It seems the movieclip unloads itself when the mask enters a new keyframe. I don't know how to work around this. I've tried making a separate movie clip out of the mask, and animating it on its own timeline, but that hasn't worked. Nothing else reacts this way to a moving mask. [URL]
I want to create a mask from an animated line. I found out pretty quick that you can't use a line to mask, only fills. So, can I convert the line to a fill as it's being drawn? Or do I need to put multiple instances of a shape along my line at intervals?
I keep seeing requests for an animation of writing. I figured it would be easier to have the text in one layer and use the animated line as the mask. It sounded good in theory.
I've attached my test that shows the line being drawn. I was playing around with some different objects to use as masks and that's how I saw that lines can't be used as masks. I wish they could.
I am bumping into a very strange behaviour on Flash.If you on the Flash IDE create a shape with a mask associated to it, save it and then export it as a swf, you cannotprogramatically know there is a mask (displayObject.mask is null)
Here's a simple test script to prove that: //executed on enter_frame with the root object function test(d:DisplayObject) : Void

I'm relatively new to flash, and just upgraded from Flash 6 to Flash 10. This is a HUGE jump for me, but strangely, I already feel more at home in Fl10 than Fl6, as it is more object oriented, and as a hardened programmer, I like.I'm attempting to create dynamically animated objects in a flash application. I can't think of a way to approach the issue without either a: converting each keyframe into a bitmap, or b: brute-force generating each frame every step of the way.Seeing as my application will have hundreds of the little bastards on the screen at any time, option b is out of the question, I presume. So, essentially, I have a few questions about AS3:
1) Can a curve be modified after it has been drawn, or must it be cleared, then redrawn each frame?
2) Can a IK chain modify curves, or is it only per-symbol?
3) How fast can flash render complex objects in 3D? (I.E. would drawing hundreds of 400+ poly objects be too much?)
4) How fast can flash draw vector objects? (I.E. would drawing hundreds of creatures made up of dozens of curves be too cumbersome?)
how to get a movieclip named "topnav" to resize it's width to match that of the stage. I am trying to resize the width of a top nav bar across a resizable RIA. I have started with the following code but with only partial success:
Code: stage.addEventListener(Event.RESIZE, resizeListener); function resizeListener (e:Event):void { var reg2 = stage.stageWidth / 100;
I have a site that is fairly complex, but was using a massive amount of CPU power, even when sitting idle on a page with no animations. I went through everything with a fine toothed comb, and couldn't find the culprit.So I just started removing layers one by one, until I found the one causing the problem.
Turns out it was a layer with an animated mask. I have a large black recatangle, that I converted to a mask, and then used a shape tween on it. Once that was triggered. The CPU usage went up 65-75%. Even when the movie was stopped on a frame that that mask didn't exist on. Once it was triggered, the rest of the time you are on the site the CPU usage is through the roof. I can do to fix that. Is there some other way I should build an animated mask?
What I want to achieve is this. I want a picture of a car that is dry as the background. On top of that a picture of the same car, but wet. I then want an image of a chamois that the user can click on and use to "remove" the water off the car, by "erasing" the picture off the top layer. Is this something that is achieveable.[code]...
I am looking at the SimpleButton entirely wrong. Here's what I'm doing (inside of a MovieClip):
[Code]...
the close_btn.width and height remain 0. Am I supposed to just rely on the DisplayObject members of the SimpleButton completely and ignore width/height/x/y or what?
I have a movie clip, in this movie clip there is a mask. I have three layers in this movie clip, 1. the mask, 2. the item being masked, 3. back ground object. When I click on the movie clip on the stage it gives me a width of 150. 150 is the width of the Mask, layer 1, and the back ground, layer 3. trace(movieclip.width); gives 175. 175 is the width of the item being masked on layer 2 of the movie clip. Is this a quark? or is there someway to get the width of the movie clip like when I click on it in on the stage?
I have notice that you can't access the width property of a mask, but you can access the x position property. Try this code var myMask:Sprite = new Sprite(); myMask.graphics.beginFill(0xFF4F00); myMask.graphics.drawRect(40, 30, 15, 15); addChild(myMask); var myMC:MovieClip = new MovieClip(); addChild(myMC); myMC.mask = myMask; trace(myMask.width); //outputs 0 trace(myMask.x); //outputs 15 How to get the mask width?
I have been racking my brain trying to figure this out for some time. I have some animated links that activate based on mouse position. The problem is when you whip the mouse over them quickly and it leaves the dimensions of the project, flash thinks the mouse is still there and the links continue their animation. IT IS EXTREMELY FRUSTRATING!! I have a feeling its a simple fix but i cant figure it out. here is the site - [URL] the actionscript is below...probably the most round about way ever devised.
