Dictionary Of Co-ordinates? Or What?
I'm planning to implement a a tiling background of loaded bitmaps.
Because I can't hold the whole map in memory at once, I figure when a bitmap is off-screen, it should be available for garbage collection. But if it comes back on screen and hasn't been collected, I want to be able to put it back in the display list without needing to reload it.
But I'm new to AS3, and don't fully understand this weak reference thing. I'll want to be able to access the bitmaps according to an X and Y index, so I initially thought of using an array of arrays to store them. But arrays don't allow weak references.
I can use a dictionary with weak references, but in that case I don't see how I can reference an object based on its X and Y co-ordinates so I can see if it still exists.

_x / _y Co-ordinates
Hi...
I'm using attachMovie method to place movies
on the stage. But because I can't see them until I
test my movie, I am placing a box where I want my
movie clip to appear, and taking the x/y co-ordinates
from the property inspector.
However, using these co-ords. in the attachMovie params.
_x and _y , They don't line up, and I have to poke and
hope until I get it right.
I have now found the co-ords for the movie I am working
on at this time. But even using these, sometimes a clip
appears on the stage very large and not starting at
those co-ords.
I'm making the clips by cutting and pasting frames
into a new movie symbol. but not sure at what stage I
should be sizing them. ?
Any comments/advice would be greatly appreaciated.

Set X & Y Co-Ordinates
Hi
I need to reset the positions of movieclips in each frame. It is a drag and drop game and after each stage I need to have the movieclips go back to their original places.
I have been unable to figure out or find how to set the x and y co-ordinates at the beginning of each frame.
Any help is much appreciated

Dictionary - XML Or TXT
Hi! I'm trying to integrate a flash movie with external data. I'm not sure if I should use XML or TXT and would appreciate some advice. The scenary is like this:
-I have a database with four records: Word, Explanation, Illustration, Video.
-The flash document should be one static page with one field for each of the records.
-Word field should be a search field and combo box.
-Explanation field should load when the corresponding word is selected. There should be links from words in the explanation field to corresponding words in the word field.
-Video field should load and play when the corresponding word is selected.
-Illustration field should be an internal link to an illustration
My problems are:
-Should I use XML or TXT for the data (Words, Explanation)?
-How do I in an easy way connect the data from the external file to the flash document?
I'm sure I'll come up with a lot of more questions later but that's enough for today. I have made an illustration of how I imagine the user interface should look like.

Dictionary Contains Key?
What is the correct way to determine if a Dictionary contains a particular key or not?
In Java I can do:
HashMap x= new HashMap();
x.containsKey("test"); // returns true/false
Is this the correct way in AS3?
var xictionary = new Dictionary();
x["test"] == null
If so, what happens if someone does:
x["test"] = null;
Thanks

Is This A Dictionary Bug?
I have an object with a dictionary member. The dictionary holds weak references to objects which have members added to the display list.
After running for awhile the objects stored in the dictionary are garbage collected, even though the objects have members added to the display list which arent garbage collected.
I realize i have weak references set for thed dictionary but should that happen?

Dictionary Bug?
i think there is a bug in the weakly-referenced Dictionary implementation; can someone tell me if i'm missing something?
ActionScript Code:
package {
import flash.display.Sprite;
public class DictTest extends Sprite {
public function DictTest() {
this.testWeakDict();
}
private function testWeakDict () :void {
var dictImp:DictionaryImplementer = new DictionaryImplementer();
dictImp.storeFunc(this.testWeakDict);
trace("retrieving:"+dictImp.getFuncVal(this.testWeakDict)); //output: undefined
}
}
}
import flash.utils.Dictionary;
class DictionaryImplementer {
private var dict:Dictionary;
public function DictionaryImplementer () {
this.dict = new Dictionary(true);
}
public function storeFunc (func:Function) :void {
this.dict[func] = true;
trace("just stored:"+this.dict[func]); //output: true
}
public function getFuncVal (func:Function) :* {
return this.dict[func];
}
}
i'm using a class member method (testWeakDict) as a key in a weakly-referenced Dictionary (stored in another class instance). it's a member method of the application class, so the method is *obviously* never going out of scope. therefore it should remain in the Dictionary object.
however, as evidenced by the getFuncVal call, the testWeakDict key is removed from the Dictionary.
i was going to post this on LiveDocs, but...there's no Add Comment button on the Dictionary doc page!! ugh.

3D Co-ordinates Puzzle
HI Everyone
back again... this seemed to be unanswered last week, so just in the hope of getting an answer this time ;o)
i have a 3d problem thats had me stumped for months and i really need to get this bit sorted out so any help would be really appreciated,,i have tried every tutorial i can find but none seem to be as straightforward as i need
anyway
i have some points
camerapositionX
camerapositionY
camerapositionZ
and
camerafocusX
camerafocusY
camerafocusZ
(general x,y,z coordiantes to a normal flash movie, im trying to use the camera focus part as the perspective point so i can move it around
now i have a layer with x,y,z values
eg:
clipX
clipY
clipZ
so in essence im looking for something to stick in a call or function type thing where the inputs would be
inputclipX
inputclipY
inputclipZ
and outputs would be
outputX
outputY
to then 'fake' the 3d coordinates relative to the camera coordinates..
i hope that makes sense ?
many thanks again

Finding Co-ordinates
Hello all,
I'm trying to make a trail of smoke clouds clips come out the back of a rocketship clip that follows the mouse around (the rocket rotates to point towards the mouse cursor and it has inertia etc.).
When I duplicate a smoke clip I want to set its x & y property relative to the back of my rocket clip, whichever way its pointing or wherever it is on the screen.
I've tried creating a small clip inside my rocket clip, at the back, and referencing the _x and _y of this clip when setting the duplicated cloud clip's properties. But it doesn't work!
Does anyone know how I can find the absolute coordinates of this clip inside the rocket clip or is there a different way I should be doing this. Hope this all makes sense, I'm really stuck and would appreciate any suggestions.

Hit Test By Co-ordinates?
Hi,
There is probably a very obvious answer to this that unfortunately escapes me at the moment.
I need to perform a hit test between a movie clip and an area of the stage. For reasons that don't really matter I can't use another movieclip. Is it possible to define a hit area by co-ordinates and width and height in actionscript?

A Button Using Co-ordinates?
Hi,
I'm stuck
Imagine a menu system where a button is draggable, as you drag it around it doesn't do anything until it it reaches a specific co-ordinate. Then when it crosses it, it loads an external movie.
O.k
There are rules though, the button needs to be able to have more than one set of co-ordinates, which are not single points but stretch across the movie (horizontal and vertical) , this is so it can load more than one external movie. Its basically a navigation.
here's a pic to help you to visualise : -

Problem With Co-ordinates
Hi !,
This is a situation in my application.
There are two movie clips A and B and B has two movie clips inside C and D. B ismoving(not static). A is static. I have to drag A on to B (so that it exactly fits at the center of C) but how can I do it? how can I map the co-ordinates of C to that of A? (coz, I can't use the co-ordinates of C, they are different from A's co-ordinates).
Please help !!

LoadMovie _x _y Co-ordinates
Hi everyone,
I have an empty movieclip on stage - abs_loader_mc - and I want to load some jpegs dynamically into it.
I need to center it on the stage by inserting the code: Code:
Thumb1_mc.onRelease = function() {
abs_loader_mc.loadMovie("path");
abs_loader_mc._x = (Stage.width/2)-(abs_loader_mc._width/w); // this should find the _x center of the loaded jpg
}
The problem is that it's centering the small circle (empty movie clip) in the center and not the actual image. Shouldn't the _width be that of the image?
If I click once on the thumbnail the image loads where the empty_mc is on Stage (before centering) then if I click again it sort of "refreshes" and snap to center position where I want it.
I can do this with an onEnterFrame or setInterval but they are CPU intensive, right? Besides I can get to delete on EnterFrame or clearInterval properly - I'm not really sure where to put either statement so on tracing I know that either they delete before it executes or they don't delete at all.
Any help would be greatly appreciated!
Thanks!

I Need Dictionary In Flash.
i am working for a project, which could possible require the functionality of a dictionary in flash.
to get an idea of what i mean. go to http://www.m-w.com/ and type in any word. and it should return the result .
For Example if i type in :- animation
it should provide me the same result;
Pronunciation: "a-n&-'mA-sh&n
Function: noun
Defination:a motion picture made by photographing successive positions of inanimate objects (as puppets or mechanical parts)
but, i need all this within flash.
as i understand it, the scripting in this would be fairly simple, however the databases is the problem. any suggestions ?

Can I Have A Little Help With Dictionary WeakKeys?
I'm new to AS3 and trying to understand Dictionaries and weakKeys. I've written the following short program which I expected to showcase the garbage collection feature:
Quote:
If the only reference to an object is in the specified Dictionary object, the key is eligible for garbage collection and is removed from the table when the object is collected.
ActionScript Code:
public function Main():void {
var dict:Dictionary = new Dictionary(true);
dumpSpriteDict("dictionary created", dict);
var o:Object = {s: new Sprite()};
dict[o.s] = 1;
dumpSpriteDict("sprite added to dictionary", dict);
o = null;
dumpSpriteDict("sprite destroyed?", dict);
}
private function dumpSpriteDict(status:String, dict:Dictionary):void {
trace(status);
for ( var key:* in dict ) {
var line:String = " ";
line += key;
var spr:Sprite = key as Sprite;
line += " (.visible = " + spr.visible + ")";
trace(line);
}
}
Code:
dictionary created
sprite added to dictionary
[object Sprite] (.visible = true)
sprite destroyed?
[object Sprite] (.visible = true)
I really wasn't expecting that last line of output! I thought the Dictionary would be empty after nulling out my Object. Can someone explain my misunderstanding?

How would you get flash to load external text from a text prompt rather than a button click ? For example you could type in "Samurai" and it will load samurai.txt or whatever text files you wanted. I am a complete beginner at action script. Can anyone point me in the right direction ?
