ActionScript 2.0 :: Tell If Something Is Within The Stage Bounds?
Jun 23, 2009
I have a bunch of images going on all at once, some on the stage, and some off, and i would like to find a way of telling whether or not they are currently on the stage or not....
I know i can do the whole
checkStage = function () {
if ((mc._x>=0) && (mc._x<=Stage.width) && (mc._y >= 0)&&(mc._y >=Stage.height)) {
//have mc do whatever here
[Code].....
that way i can satisfy my laziness AND achieve what i'm trying to do without having to deal with long winded paths and a bunch of else if's

I have a simple MC on the stage. I want to create a simple conditional statement that would check if the mouse is on the rectangle using get bounds. something like [code]Basicaly...how do I properly use the getBounds in a situation like this?

I have a "circle_mc" movie clip and its registratoin is in the center but it moves and works fine but i dont want it to go off the stage half way I want it to stop before it goes off
ActionScript Code:
circle_mc.onRollOver = function() {
this.dx = Math.round(Math.random()*Stage.width);
this.dy = Math.round(Math.random()*Stage.height);
this.onEnterFrame = moveIt;
}; function moveIt() {
this._x += (this.dx-this._x)/10;
this._y += (this.dy-this._y)/10;
if (Math.round(this._x) == this.dx) {
this._x = this.dx;
}}

When using the Loader class to load an external SWF into another timeline and then displaying that SWF using addChild on the loader.content, one discovers to one's consternation that elements positioned off the stage of the external SWF are still displayed.To illustrate this with an example: suppose you have a 500x500 pixel "main" SWF, and it loads an external SWF at runtime and positions it in the center of the stage. And suppose that this external SWF's document properties set the stage width to 200 x 200 pixels. However, when authoring this external SWF, we draw a box that's 300 x 300 pixels, so part of this box is actually off-stage.
When you play the external SWF in the standalone Flash player, it is sized correctly at 200 x 200 pixels, and the rest of this box is cropped off.When you load this external SWF into the "main" SWF and use addChild() to put it on the stage, you will see the full 300 x 300 pixel boNow of course, we can simply solve the issue using a mask, but I'm wondering whether there's a more elegant solution that's built in, either to the MovieClip or the Loader or the LoaderInfo classes. Something that says "respect the document bounds of the original SWF" or "crop to stage dimensions".

If an object exists outside of Flash's stage boundaries, is on the Display List, and is visible, is it causing a performance hit from Flash rendering it? In other words, does Flash render what isn't seen?
This leads me to believe so:

is it possible for flash to detect off-stage mouse coordinates in order to continuously drag an object within its bounds while the mouse is moving outside of the stage? for example: i have a draggable red square on my stage. the stage is the bounds of the drag. if i drag the red square to the bottom of the stage and continue to drag outside of and around the stage, i'd like the red square to continue moving within it's bounds, following the mouse coordinates. currently, dragging halts as soon as i leave the stage and the red square only begins to move with the mouse coordinates if i reenter the stage bounds.

I have my stage set at 500px x 500px. I have a map mc on stage that is 2500px x 2500px and I am trying to mouse scroll the entire map mc inside the bounds of the 500px x 500px stage. The map mc xy ref coordinate is in the center of the graphic. This is a math problem for me. An example would be [URL]

Although I put _x = player._x etc. code in an onEnterFrame function the masking mc is moving without the player
You see...the player is held within some borders. When cornered and then hit, the mask moves according to how it would move normally, but without the player (because he is held in place by some borders)...
Also, if I don't have a problem but I'm missing a crucial piece of code,
code on masking mc
ActionScript Code:
stop();
this._x = _root.player._x;
this._y = _root.player._y;
radiance = 180 / Math.PI;

for some reason this flex 4 code gives me an error but I can't figure out why. In my WindowedApplication I have:[code]That seems like a bogus error since I can assign pref.bounds to rect without an error. I don't know why this isn't working. It works under flex 3 compatibility mode but that also breaks a lot of my spark components so I can't use it.

I have a script that produces random motion along the y axis, however, I want that motion to occur within the movie clip that is centered on the stage, or I should say within the bounds of that movie clip.
The movie clip has a height of 335 px

I am wondering if there is an easy way of monitoring whether or not an mc is within the boundaries of another mc while it is being dragged. Currently I am using different equations to determine the leftmost, rightmost, topmost and bottommost points of each mc and then when they are being dragged comparing their x,y coordinates. Is there an easier way... I ask because this seems to be quite a lot of code to get through for such a simple operation, especially when the function containing the code is being called each time the mouse moves..

I am trying to make this an kinda interactive map in flash. I will try to explain it for better explanation. Here is an image of the output I have a jpg image(converted to movieclip) which is way larger than the stage.
[code]...
Then I have a mask in the center of the stage and user sees a portion of the map and is allowed to scroll to move mouse around to see areas around the focused city.
[code]...
I put this numbers in by playing around but where are these values exactly coming from. I have tried everything(every possible way) but cant figure out what are these values. I need to numbers to be dynamic so I can change the focus to different cities(for example when a user click A city A should be seen inside the mask and so on).How can I make these values dynamic instead of hard coding them.

So I am trying to save a screenshot using JPGEncoder while in full screen mode. The document size is 100x700, and the stage is aligned to bottom. I've been able to capture the right size, however it always seems to capturing the image from the wrong start x,y position. There is some elements out of bound but I am just trying to clip them.
Here was last attempt :
Code:
stage.quality=StageQuality.HIGH;
stage.align=StageAlign.BOTTOM;
StageScaleMode.NO_SCALE;

I am creating an app that has to load a image or swf on to the stage and dynamically place and position it on either sides of the stage i.e. (top, left, bottom or right).how can I dynamically calculate the remaining bounds of the stage using the bounds of the dynamically placed loaded image/swf. ?e.g if the bounds of the loaded clip isRectangle(x=10, y=10, w=250, h=800);What is the remaining Rectangle() to use ofRectangle(0,0,1024,800); ?
e.g if the bounds of the loaded clip is
Rectangle(x=0, y=0, w=800, h=50);
What is the remaining Rectangle() to use of

DisplayObject.getBounds in actionscript returns the bounds of the object with the strokes included. The left, top, width, height properties of a SymbolInstance in JSFL don't seem to include the strokes. That's the only way I've found to get the bounds of a symbol from JSFL.

I'm working with the Flash Api for Google Maps in my Actionscript/Air project. I now need the latLngBounds (the top left, top right, bottom right and bottom left) values of the current view of the map. The function map.getLatLngBounds should do that, but it always gives me a really low lat/lng bounds back. Always somewhere around:

It happens when you drag the scroll slider out of bounds and you release - even when mouse is up the slider still moves. I consider it a glitch. What does somebody has to do to fix it?the code I use for the slider:

I'm adding a bunch of movieclips to a container clip. I then add that to the scrollpane. When I run scrollpane.update() it gives me the error "The supplied index is out of bounds". From the full error message it looks like it's happening on the DisplayObjectContainer/getChildAt() which is run in the update() method. I thought I had it going once but now it's not again and I can't figure out what I was doing differently.

I wish to stop my mask being dragged outside the bounds of the image. The current set up I have is as follows. I created a circle and added a blur; I then exported it for action script setting its class as a sprite with the class name "Circle". I also made my image i was going to mask a Movie clip with the isntance name "mc_bee". In the actionscript I added it to the stage, positioned it and cached it. I tried to add in actioscript to create the bounds the image the mask is making with the code below:
