I have a movie clip named circle_mc(see the image on the link below) and a mask object(movie clip) which determines visible area of the circle. User can change the portion which is visible (extend the red area and make it red+blue, gray area is invisible). I need to find proportion of visible area to invisible area (red+blue/gray) so that I can calculate angle.

I have camera input app in flash (AS3) and I draw some graphics over it. I want to take the image snapshot of the stage visible area but only the video an graphics I draw over video. I want to exclude controls from the image snapshot. My display object layout is in following relation:
-stage
--canvas (Sprite)
---video (Video)[code]..........
Stage size is fixed and I want to take a image snapshot of everything that is child of my canvas element (camera input video and overlayed graphics, but excluding controls). I am able to make this image snapshot when overlayed graphics are inside the bounds of stage size. I do it like this:
var bmpd:BitmapData = new BitmapData(canvas.width, canvas.height);
bmpd.draw(canvas, new Matrix(1, 0, 0, 1, canvas.x, canvas.y));
But this gives me unwanted result when graphics which I draw on top of video on canvas exceed the bounds of stage display area. How do I limit the image snapshot only in the bounds of visible area inside stage?
Basically I'm trying to resize images in flash to fit the masked area but proportionately....
My mask area is:
Code:
width = 478;
height = 420;
now consider that the the max width I want my pictures to be. This doesn't have to be exact. Now what I came up with to resize proportionatly is:
Code:
//width & height are my mask deminsions ( which i wanna resize my pics to)
//width_orig & height_orig are the deminsions of each new loaded pic.
height = (width / width_orig) * height_orig;
width = (height / height_orig) * width_orig;
That does scale them proportionatly but some of the times it will resize a lil bit smaller than the image area which I don't really want. Like I said this doesn't need to be exact. I would prefer it to be a lil bit bigger than the masked area. I just need to make sure the pics are scaled proportionatly.
I am loading an external swf using the SWFLoader component. The swf that is being loaded is masked so that only a portion is being shown. However, when it's loaded the actual size of the swf (loader.content.width/loader.content.height) is the complete swf including the masked area. Therefore, the loaded swf does not display properly in the itemrenderer Is there a way to to grab the size of the just the masked area as opposed to getting the size of the entire swf's contents? also i need to re size the masked area
View 1 RepliesI'm trying to know if there's a way in ActionScript 3 to load a PNG image and make some sort of button or sensible area applicable only for the visible area of that PNG??Maybe there's a simple way to define a polygonal area on execution time, I mean, dynamically and make it sensible to mouse events??

View 3 RepliesI have several objects that share a single mask. I can see all of them when wmode is set to window but i want the background image on the page to show through the flash and have designed the flash around that. However when I set the wmode to transparent some of the objects don't render at all even though others do and they share the same mask.
View 3 RepliesI have some movie clips turned buttons (by way of mc.buttonMode = true and friends) that scroll by an invisible button area, and when they are 'under' that area, none of their mouse events work. How can I still catch their mouse events in addition to the MOUSE_OVER of the invisible button on top?
View 0 Repliesi have a drop down menu am working on and each button tab (although they are not button instances !) when clicked opens up the "drop down" section which you can mouse over to choose another specific button etc - if you mouse out of that drop down area then it pulls back up to the original tab state .. what do i change to the code below to decrease the area that you mouse out of to make the drop down area pull back .....at the moment it at least two inches on the screen below and to the right of boundaries of the drop down box before it pulls up - i want to it pull up as the mouse leaves the boundary box .... hope this makes sense .... there is some part of the actionscipt below that controls this but can work out which bit and how to change it !!!

I have this function:
public static function cloneDpObj(target:DisplayObject):Bitmap
{
var duplicate:Bitmap;
[code]....
to clone target displayObject (MovieClip or Sprite) and return Bitmap Object.
It can get bitmap from the target object, but it seem don't get all the area of the image.
By give the width and height of target object, but the target object in design was applied by Glow Effect, so my question can we get the all view of bitmapdata from a displayobject?
I would like to first add the xml to my flash. Fine I can do this.But I have a number of buttons, where when I click say CW1, i get the information from the XML file with a node of CW1. I have all the xml set up fine.As I have about eight different postcode types.
ST, CW, CH, TF, WV, WS, DE, SK, SY, and each of these may have numbers that follow, i.e ST1, ST2, ST3 and so forth.
So I can only assume that the postal area could be the main nodes, and the numbers inside the child nodes, am I right thus far.o how can i load the area of the xml file into my text area on mouse click, pulling the information relating.
In many cases the pieces have artifacts outside of their visible area. For example, a piece can have a picture of a dog's face, but one of the long ears is off to the side, outside the visible region of the piece. The path data is extremely detailed, so our designers didn't crop it off. They used a mask (at least I think it's a mask, I'm not a graphics guy and know little about that stuff) and this makes it invisible in Flash, when we turn them into movie clips. Also, in Flash when I look at the width and height of the piece, it does reflect only the visible area.However, in ActionScript when I try to get the width and height using, for example
Code:
pieceObject.width
I get the width of the piece including the part that is hidden, i.e. a larger width than the visible area.Is there a way in AS 3.0 to get the height / width of the bounding box of visible area only?
I have a AS2 movie clip that has a drag navigation. The movie clip is bigger then the visible area. How can I find the center xy of the current visible area when I stop the drag?
View 2 RepliesI'm working on a game where if the person puts there mouse over a card, it should pop out over the other cards, and when moved off, the card should go back to where it was, i can get the card to pop out no problem, and go back to it's location, the thing is, i don't want the card to go back when i move off the entire image, only when the mouse moves off of what was originally visible, and i'm not certain how to obtain a pre-visible area that i can use to test if the object should still be over all the other cards.
View 5 RepliesI'm making a first-person adventure game where I have the different frames in the root movie be the various locations that the user can interact with. I want to have fading transitions between the scenes and I was wondering if this was possible in flash. What I've tried for now is to create an array with all the current children then when the frame is changed I add those objects on top of the new frame and use a (alpha) Tween object to fade them out. This doesn't seem like a good idea and feels very hackish, so I had a few questions:
1. Is there an event that is called when a frame is changed (Event.FRAME_CHANGE doesn't exist ) since the way I'm doing it now is to have a local variable which I compare with this.currentFrame.
2. This may sound weird, but is there a way to create a screenshot of the current visible area and use that as one would any other visible object? This would allow me to Tween that one out instead of the array of children that I'm using now. I know it's possible in OpenGL, to render the current view scope to a texture array, but does Flash have this capacity?
PS: This is all done inside a separate class, in case that matters (I am very noobish).
I would like to know how to have the cursor visible in non editable Text Area.
View 7 RepliesI am trying to determine the global coordinates of the visible rectangle that is currently rendered on the stage.
Specifically, if a canvas has an explicit height and width and is a child of a panel that has a scrollbar, the scrollbar can "hide" a part of the canvas. ContentToGlobal(x,y) provides the global position of the content at the time, but content coordinates can scroll off the boundaries of the parent panel and continue to give x,y coordinates that are not visible.
Is there a way to determine the viewable rectangle that is not hidden by anything?

View 8 RepliesI've got the following situation, where I have an outer Vbox that is set at a fixed width, and then inside it there is a header made from an HBox and a content area (Canvas) that is much wider than the enclosing VBox (and therefore requires scrollbars on the outer VBox to see it all).
I would like to set the width of the header to fill the entire width of the outer container, but only the visible part, and to remain fixed so that when I scroll to view the content, the header doesn't move.

I have some movieClips on stage which are draggable and I don't want them to be draggable outside of a visible stage area. Problem is these movieClips are inside a sprite which is panable and then for whatever reason this bounds doesn't work anymore as I intend it to. How do I fix this bounds?
Code:
var arr:Array = [m1,m2,m3,m4,m5,m6,m7,m8,m9,m10];
var thumbSprite:Sprite = new Sprite();
addChild(thumbSprite);
for each (var item in arr) {
item.addEventListener(MouseEvent.MOUSE_DOWN, startDragCard, false, 0, true);

View 1 RepliesWhat I'm trying to do: build a super simple button skin (say a small circle when in up state, slightly larger circle when in over / down states) that has a larger mouse hit area than visible area. In other words, I'd like the button to look like a 5x5 circle when in up state, but transition to over state when the mouse is in a 15x15 pixel area around such circle - in order to make clicking on the button easier.
What I've done in the past is to use a transparent ellipse behind the the visible ellipse. This works nicely but seems like a waste of memory (not much, although if you start having a lot of these buttons it adds up) and rendering cycles (transparency). I thought I could avoid this by wrapping the ellipse in a group with a given size and listen to its mouse events, but somehow no mouse events seem to fire on such a group - not sure why.
I guess I'd love to know if anyone knows an efficient way to do this. Also would love to know why such a group won't fire mouse events, but I guess that's secondary. Simple code snippet below:

View 1 RepliesI have a simple FLA that pans through an image up/down/left/right. There are several hotspots (transparent buttons) that popup simple captions when the user rolls over them and launches a URL when clicked.
The captions are actually one caption that I dynamically write text to, size, and _x, _y locate when the rollover event occurs.
The caption (cap) is a rectangle and text box MC symbol which is grouped with the graphic and buttons as another MC symbol. It all works great, panning, captions.
The problem is, when the mouse is first moved, the caption box appears over the graphic. I want it invisible until a rollover occurs. I have tried a setup function action in the first frame that performs cap._visible = false;, which did not solve it. That syntax works fine following the first rollout.
on (rollOver) {
cap.desc.text = "Mr Reynolds";
cap._width = 7*cap.desc.text.length;

I have made a movieclip and gave the frame this actionscript:

it moves fine and stuff but i was wondering how can i restrict the area in which the movieclip can actually move ? my flash file is 550px X 400px and i want to make it so that it can only move in 300px X 200px of the file if you understand ?
I have a startDrag function set up on a loader and mask that when the mouse is down on the loader it drags, when not it doesn't. There is also 2 buttons that control whether mask1 or mask2 is used. What i would like however is when the mouse is down - the area of the loader outside of the mask is visible but only by about 10/20% alpha, that way the user can see where all the image is while dragging. Is this possible? Full code can be seen below and i have attached the zip with the .fla file:

I have a picture in a BitmapData object. And an array of points. I nead to erase the part of the picture inside a polygon specified by the points. In other words, draw a polygon specified by the points and fill it with transparency.
I have a .fla set up right now that places ball randomly around the screen. However I would like to be able to set the coordinates of the range for the objects(particles) placement to the boundaries of a shape. I am starting with a circle for the moment, but I can't figure out how to set the range of object placement to that of an MC. I was planning on somehow calculating this out but I am stumped. Is there a better way for me to draw a shape, and somehow use a mask in as3 to define where the particles can no be placed?
