RE: [Flashcoders] determining which object is displayed at agivenpoint
I think he is referring to the following class from another thread. One problem pertaining to your issue is that it doesn't take into consideration depth. It is still more process intensive then just firing a callback on rollOver but could be useful for you and give you some ideas: class com.domain.RollWhileWithin extends MovieClip { public var rolled:Boolean; function RollWhileWithin () { rolled = false; } public function doRollOver():Void { if (!rolled) { rolled = true; gotoAndStop(over); } } public function doRollOut():Void { if (rolled) { rolled = false; gotoAndStop(up); } } } One level above it, you can manage as many clips as there are. var checkMouseInterval:Number; clearInterval(checkMouseInterval); checkMouseInterval = setInterval(this, checkMouse, 100); private function checkMouse():Void { var i:Number = 5; while (i--) { var clip:MovieClip = this[MC_RollClip + i]; if (_xmouse clip._x _xmouse clip._x + clip._width _ymouse clip._y _ymouse clip._y + clip._height) { clip.doRollOver(); } else { clip.doRollOut(); } } } -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vishal Kapur Sent: Thursday, February 08, 2007 11:19 PM To: Flashcoders mailing list Subject: Re: [Flashcoders] determining which object is displayed at agivenpoint Ok. This is what I was missing. Thanks to Karina and Erik for pointing out that you need to compare the entire parent chain of two objects to figure out which one is being rendered above the other. The only thing to add is that in addition to checking depths, the _visible property needs to be checked for the parent chain for each object (so if _visible is false anywhere in the parent chain, I consider that object to be invisible). This works in all cases except for some TextFields, where the bounding box of the textfield object is bigger than the area actually occupied by the text. This can be solved with a custom hitTest() implementation that uses Textfield.textWidth and .textHeight to get the bounding box of the displayed text. An interesting corollary is that this method would be a way to implement onRollOver for TextFields (if that ever proves useful to anyone). Steven, I'm not familiar with the class you're referring to.

As I mentioned in my first mail, depth, _visible and _alpha are the properties I'm checking right now to resolve conflicts. So my code looks very similar to your code below. This works sometimes, but I've run into cases where there are 2 movieclips for which hitTest() is true, _visible is true, _alpha is 100, and the depths are identical. One of the movieclips is obscured behind the other; there must be some way to distinguish them. Are there any other properties on movieclips (maybe hidden ones) that might be of use? The Flash runtime must be doing this internally for onRollOver event firing; anyone know how this works? Thanks, Vishal On 2/7/07, Karina Steffens [EMAIL PROTECTED] wrote: Ok, I see your problem, so lets think what else you can do with the hitTest approach... First of all, you can set the shape flag to true, so that the hit test will only return true if there's something there (as opposed to the entire bounding rect). Then you can test for _alpha (you might want to test for _visible also), thus eliminating invisible buttons, such as your big rectangle that obscures the rest. Finally, checking for different depths - I recently discovered that if you loop through a clip, it starts at the highest depth, even on the same layer: for (var i in _root) { trace(i + +_root[i].getDepth()); } $version clip3 -16379 clip2 -16381 clip1 -16383 So now you know which one has the highest depth: clip3, which also comes first in the loop. At this point, you can break the loop. If you need to go deeper, you can then recurse within that clip, and see if it has any child mcs, which one of those scores the highest hitTest and if that one has any children - etc. Here's some quickdirty code: for (var i in _root) { trace(i + +_root[i].getDepth()); } _root.onEnterFrame = function() { for (var i in this) { var clip = this[i]; if (!(clip instanceof MovieClip)) { continue; } if (clip._alpha == 0 || clip._visible == 0) { continue; } if (clip.hitTest(_root._xmouse, _root._ymouse, true)) { trace(clip); break; } } }; On the timeline, I placed three circular clips overlapping eachother, so that clip1 is at the lowest depth and clip3 at the highest. I made clip3 invisible by setting it's alpha to 0. After moving my mouse over the clips, starting from the third, the trace result was: $version clip3 -16379 clip2 -16381 clip1 -16383 _level0.clip2 _level0.clip2 _level0.clip2 _level0.clip2 _level0.clip2 _level0.clip2 _level0.clip2 _level0.clip1 _level0.clip1 _level0.clip1 Each time the trace picked out the highest visible part of a clip, thus resolving any conflicts.

If performance isn't an issue, you can use getDepth to figure out the top most mc / textfield and then just act on it (place into a zorder array and use depth for index).

RE: [Flashcoders] determining which object is displayed at agivenpoint
For every mousemove or enterframe (however, you decide to check hittest) you have to loop through and hittest every movieclip you want to check. So say for example we are talking about just 10 movieclips checking using enterframe at 30 frames per-second (assumming Flash Player is actually running at 30fps) you're technically looping through 300 movieclips persecond and running 300 hitTest persecond. That's a lot of processing for just 10 movieclips. Which is why I suggest using some other method. If you setup a test calculating FPS you'll see that hitTest / looping will tax the processor much more then setting an onRollOver. -erik -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Boyd Sent: Wednesday, February 07, 2007 11:43 AM To: Flashcoders mailing list Subject: Re: [Flashcoders] determining which object is displayed at agivenpoint I've been following this thread and am just curious -- everyone seems to be assuming that looping through all clips and doing hitTest() is inefficient, but presumably this is exactly what the Flash player is doing with every mouse move.

I'm not sure how your app is structured but if you can't put your movieclips above this 3rd party movieclip you wont be able to use _droptarget (as you've already discovered) unless you can set that interfering movieclips visibility to false. I'm not sure how / why you want to check what mc the mouse is over, but you could also just manually set movieclips to set an over variable onRollOver / onRollOut or onPress. The reason why I'm suggesting one of these methods is that all other options will be much more complex, processor intensive and time consuming. Unfortunately there is no getMovieClipAt(x,y) method. Your best bet is to think about what core functionality you really need and go with the cheapest solution. So if your goal isn't as broad as knowing EVERY movieclips position / depth maybe you can put a few invisible movieclips over the 3rd party clip that represents the position of the mcs you really care about. -erik -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Vishal Kapur Sent: Tuesday, February 06, 2007 5:26 PM To: Flashcoders mailing list Subject: Re: [Flashcoders] determining which object is displayed at agivenpoint Ok, got it.

In simple cases I have been able to do this by looping through a list of possible target objects and calling hitTest() on each one. However, issues arise when there are multiple objects for which hitTest() returns true. This can happen with hidden objects, or more often, objects sitting on layers that aren't currently visible. Sometimes I can compare the depth of 2 conflicting objects, and I assume whichever one has a larger depth is rendered in front of the other. This doesn't always work, however. I am debugging a case where there are two objects that return hitTest()=true, have identical depths, have identical bounding boxes, and both have _visible set to true. Only one of them is actually visible to the user at any given time, however. What other properties of a movieclip can be checked to determine if it's really the one that the user can currently see? Or is there a better way to do this, rather than using hitTest()? Let me know if I can clarify.

RE: [Flashcoders] Flair Pattern bad mixins good (?)
Just to clarify mixins and strategy are a bit different. One is more structural while the other is more behavioral. Also mixins aren't really considered a design pattern but it is made up of composites, proxies / facades (all structural design patterns ) + interfaces. They are used to emulate multiple inheritance. So something could have functionality of say a MovieClip and a Sound Object. The strategy design pattern is used to encapsulate interchangeable logic (layout, validation, etc). However, I think what you're really asking is more of an architectural question so I would take a look at ARP and Cairngorm. Cairngorm is labeled for Flex but can be easily adapted to Flash development. Similarly ARP is thought of as being used for slides but can be adapted to using MovieClips. Just a note, Cairngorm is less prescriptive about how to structure your views (which may or may not be a good thing depending on your disposition) so if you're already pretty far a long in your development check out Cairngorm Cairngorm: http://labs.adobe.com/wiki/index.php/Cairngorm ARP: http://www.osflash.org/ARP If you want want something a bit more fine grained you can do a search on MVP (Model View Presenter) or MVC (Model View Controller).

OK, this is helping a lot. And Steven I see what you mean, poor Flair is starting to look a little meager now. In my app, I have several different states. Each state sets itself up by initializing variables and drawing its various pieces, and the final piece is to subscribe various parts of the app to events that happen in other parts. So in one state I have methods like: onRoomObjectPress() onRoomObjectRelease() that are triggered by onPress and onRelease events in my object movieclips. These onSomething() methods contain the core logic of the app--code to resize clips or process values or what have you. This structure is good because I know where to look to track down where things happen, but its bad because sometimes a bunch of things are supposed to happen at once and those onSomething() methods get hairy. So in this new mixin strategy (which does look a lot like Strategy, thanks James!), should I design my Snappable class to have methods that would map to movieclip events, such as: startObjectDrag triggered by obj_mc.onPress checkForSnaptriggered bysetInterval or onEnterFrame type of event, in this case onObjectDrag stopObjectDrag triggered byobj_mc.onRelease Am I headed in the right direction?

So for example: Say you wanted to make an object dragable, clickable and resizable. You would then create separate classes called: Dragable, Clickable and Resizable (common naming convention for a mixin). Then your base class would just inherit form those 3 classes. Since AS2 doesn't support multiple inheritances you can emulate a mixin using interfaces and composed classes. For example: IClickable, IDragable, IResizable So then your AS2 class would say: Class MyClass extends Whatever implements IClickable, IDragable, IResizable Those interfaces just specify what methods your class has to support. From there you could have a class (or a consolidated class) implement that functionality private var clickable:Clickable = new Clickable(); private var dragable:Dragable = new Dragable(); private var resizeable:Resizeable = new Resizeable(); from there you just forward / wire the appropriate methods to its corresponding instances. public function startResize() { this.resizeable.startResize(); } Or for arguments: public function startResize() { this.resizeable.apply.(this.resizeable.startResize, arguments); } You could get even more fancy by externalizing those classes so based on various rules you could pass in different resize logic, etc. Anyhow, hope that gets the gears turning. =) DISCLAIMER: Didn't spell check or test anything in the compiler so maybe some typos. =) -erik -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of David Ham Sent: Monday, January 29, 2007 7:12 PM To: Flashcoders mailing list Subject: Re: [Flashcoders] Flair Pattern bad mixins good (?)

RE: [Flashcoders] Flair Pattern bad mixins good (?)
I've seen examples of it both ways where a decorated object maintains the objects interface or it adds additional methods so it breaks polymorphism. Don't have the GOF book with me to reference so no idea what they actually outlined. Doing a quick search wikipedia states 1 to 1 where doFactory shows otherwise.

Respectfully, Isn't that like saying a singleton is just a class that manages a factory? =) A design pattern is a repeatable solution to a commonly occurring problem in software development. So if all a Flair does is manage decorators and 2 people know that's what it does, then that sounds like a design pattern to me (unless there's a ECMA committee for that now a days). =) Anyhow I tend not to use decorators (matter of personal taste).

There are no references to the Flair design pattern anywhere else because it doesn't exist anywhere except in the ego of Brendan Hall.

If the room object has snapping enabled, the SnapFlair class adds an object with a bunch of methods and properties to it.

I can size it just right so the vertical scroll bars aren't visible, but anytime I try to size my swf where the scroll bar would normally be displayed it automatically scales it down to fit inside the window.

Hey thanks for the info Harald. I fiddled around with it some more and on the Verizon XV6700 I got it pretty locked at 240w x 245h running in default mode with leftMargin and topMargin set to 0. Nice and tight all the way around the bottom and top nav bars.

The only way I found to eliminate both scroll bars is to set the View menu option in IE to One Column otherwise I can't get rid of the horizontal scrollbar. I also experimented with various size parameters and scaling to determine the optimal setting for my needs.

Interestingly this required me to set my scaleX / Y values to 160 to scale the movie down to 80% of its original size. If I open this application in a desktop web browser it is actually scaled to 160% so I only see one corner of the UI. The applicationWidth of 290 and applicationHeight of 301 allowed me to display the entire screen without the need for any scrolling. One pitfall that I found was that i couldn't make use of full screen mode since my application needs to access the virtual keyboard for data entry and I haven't found any way to programmatically access it.
