Re: [Flashcoders] What design pattern would this be?
I also still find it sometimes hard when to decide what pattern to use and mostly _if_ I should use a pattern. It helps me a lot to really think about what the responsibility is of a class and then when I notice it has more then one, then that is an inidicator I need to refine more. Sometimes refining means that I _can_ use a pattern, it doesnt always mean that I should use one. I think these are those things that take a long time of experience. Good luck.

[Flashcoders] E4x replace nodename
Hello list,
i make the following query on an xml file to retrieve a list with
certain node names:
var tXML:XML =
<[EMAIL PROTECTED]>
<[EMAIL PROTECTED]>
var pat:RegExp = new RegExp('findname' , 'i')
var tList:XMLList = tXML.*.(pat['test'](name()))
This works fine, but know i would like to in addition to finding them
also remove the 'findname_'
I could use this:
var tList:XMLList = tXML.*.(pat['test'](name())).(editNodeName(name()))
function editNodeName(tObj:String):void{
trace('-> ',tObj);
}
And then create a new XMLlist with custom nodes. But how do I access the
currentNode in the query instead of the name().
Or is it possible to directly do a regExp replace on the node?
Thnx

[Flashcoders] runtime instantiation
I know it is possible to instantiate a class at runtime, but one always needs to put in a concrete piece of code that forces the compiler to actually add the class to the swf. I am currently looking into using this technique to gain flexibility in an application, but the fact that I will always need to add concrete code to force the compiler seems to be counter productive. Here is what I have. interface aInterface class abstractA impl aInterface class injectedB extends abstractA class injectedC extends abstractA then I have a factory method that reads an xml file and instantitated a class based on the @reference node using getDefinitionByName() My idea is that I can in the future write an new class injectedC and just add it to the xml list. But this won't work because I will always need to add something like this to var foo:injectedC = null to add the class to the compiler. Meaning I will always need to recompile. Is there any way to get around this?

[Flashcoders] Question on architectural problem.
Dear List, I am having a architectural problem and would like to ask people on this list for some input. The project that I am working on uses several models, we call them proxies,i.e RemoteProxy, GameProxy etc... They all extends a base class Proxy and implement an IProxy interface. The chances are in the future more proxies will be added. The person that build the system gave every Proxy an getInfo Method, the method looks like this getInfo(sIdentifier:String) : Object. Where every return object needs to be typecast to the expected return type. The reason of this function is that custom methods can be called from a proxy. This creates flexibility but comes with a price. The compiler can't check it. I can understand the reasons why this method is implementated, not having a zillion extended interfaces, not having to add import etc. But I would like to know if some solution excists that deals with this in an elegant way. I read about the Bridge pattern, but I am not sure if this will help me? Thank you.

Do the regExp replace on the string.
Reparse the XML?

Might not be the fastest in the world, depending on the amount of XML
you are parsing, but it'll do the job.

I don't think that Adobe is especially interested in promoting FlashPaper, which is essentially a competitor or substitute for PDF. What a same, because it has some nice features. Come to think of it, now with the PDF isnt possible to embed flash content and doesnt that open up a way to do some interesting flash stuff with a pdf.

Re: [Flashcoders] Document viewer
It has been a year ago and I'd thought Adobe would have brrought out an update by now. Geuss not! The problem I then had was that the client had word docs that contained a table of index. Some links would get destroyed when a doc had more then I thikn 100+ pages. Also href links would get destroyed. It was a disaster and we ended up splicing the docs.. I would really advice testing with the biggest doc you have. Jiri Stuart Campbell wrote: Really? Some of my docs will be 200 pages long. What problems did you have exactly? I'm also having "fun" because I thought FlashPaper would allow me to restrict copy and paste and printing. But it only seems to do that for PDF output. Quite dissapointed that Adobe haven't taken FlashPaper forward. On Fri, Jun 27, 2008 at 12:25 PM, Jiri Heitlager < [EMAIL PROTECTED]> wrote: Be carefull with huge documents in Flash Paper.

Thank you, Jiri Heitlager Abe Pazos wrote: The company where I work is growing and needs more AS3 developers.

Re: [Flashcoders] Question AIR Sqlite api
Thanx Muzak, I will try your solution
Muzak wrote:
I think I had a similar error when one of the statements wasn't valid.
In this case I'd think that one of the tables already exists (which ends
the transaction) and when the next statement is exectuted it throws the
error you see.
Here's something I used:
try {
_sqlConnection.begin();
//
// sql statements here
//
_sqlConnection.commit();
}catch(e:SQLError) {
trace("- message; ", e.message);
trace("- details: ", e.details);
_sqlConnection.rollback();
}
}
When creating a table it is a good idea to check if the table already
exists.
'CREATE TABLE IF NOT EXISTS ...'

Re: [Flashcoders] Question AIR Sqlite api
Morten, i just burst my own bubble. It appears not to be working after all.
It seems the line Sql_conn.openAsync( Sql_db ) in the build() method is
the problem, becuase when I change it to
Sql_conn.open( Sql_db ) everything works fine.
Do you have any other suggestions?

Re: [Flashcoders] Dynamic class instantiation
OK, I understand, without it the classes dont exist and therefor equals
to null.
Cheers!

on its own isn't enough: you need a concrete reference to a class for
its code to be included in the SWF.
Something like:
import com.mypack.MyClass;
import com.mypack.MyOtherClass;
// somewhere in the startup of your app
var dummyClasses:Array=[MyClass,MyOtherClass];
should be enough to get them compiled in.

Re: [Flashcoders] how to check if child exists
From the help files and modified a bit. It is probably more efficient
to keep track of names and the do a getChildByName(string)
function traceDisplayList(container:DisplayObjectContainer,
DispObjToCheck:DisplayObject) : Boolean
{
var child:DisplayObject;
for (var i:uint=0; i < container.numChildren; i++)
{
child = container.getChildAt(i);
if(child == DispObjToCheck){
//found it and break out of the loop

Re: [Flashcoders] Some feedback on a coding design question
Thank you for the reply. I will take a look at the state Pattern.
Reading your post, I does look a bit like what I proposed. In the state
pattern, I would probably create the layout and the types of buttonsets
for the panel create in a object. The state of the panel then determines
wich state to load and display using composition.
Did I understand your comment correctly?
Jiri
Raymond Simmons wrote:
Jiri,
Sounds like the state pattern would be helpful here. Define a class for
each state of the application. Each class will contain methods for
actions the user can take in that state, like selectListItem. When the
user takes the given action (ex., selecting a list item), the associated
function in the current state is called, and the correct actions are
performed. Once those actions are performed, move the application to
the new state. Essentially the current state class decides what actions
to take in response to user interaction with the application.

Subject: [Flashcoders] Some feedback on a coding design question
Hello List,
I am currently building an application that uses panels. The Panels
implement a Composite Pattern. The panel holds instances of
panelButtonSets class.
The panel displays certain sets based on a selected item in the client
code.
Now my question is, how do I get around a lot of if statements in the
panel like so:
if(clientcode.selecteditem.type == 1){
panel.addSet("position_panel")
panel.addSet("rotation_panel")
panel.addSet("edit_panel")
}else if(clientcode.selecteditem.type == 2){
//different sets of button sets
}
etc...
One solution I am thinking about is the following, but I would like to
get some feedback on this approach.
BasicButtonSet() {
addSets(new panelButtonSets("position_panel"))
addSets(new panelButtonSets("rotation_panel"))
}
ColorButtonSet() extends BasicButtonSet {
addSets(new panelButtonSets("color_panel"))
addSets(new panelButtonSets("brightness_panel"))
}
var basicSet:ButtonSet = new BasicButtonSet();
var colorSet:ButtonSet = new ColorButtonSet();
Then the selected item holds a reference to a certain set that can be
loaded into the panel.
var set = selectItem.GetButtonSet();
Panel.loadSetObject(set )
{
for every set in the parameter set, call its render method and place
it at the right position
};
The thing in this solution is that every set is allready instantiated
and therefore is probably a quit expensive solution?

Re: [Flashcoders] AS3 MouseEvent target?
I think the best way to learn about Event Bubbling is understanding the Composite desing pattern. This is the pattern the DisplayList is implementing and bubbling will make much more sense when you understand the workings of the Composite Pattern. At least it did for me. Jiri Steven Sacks wrote: IMO, explaining Event Bubbling as the reason the TextField is the target is complicating the immediate solution he needs, which is mouseChildren = false. Yes, it's Event Bubbling that's causing the target to be the TextField. To understand Event Bubbling, read about it in the docs, or better yet, in a book (like Moock's). But, then you MUST do it yourself to learn how it works. If you don't play with it yourself, you will never "get it" no matter how much somebody explains it to you. I'm fully convinced of that. You gotta mess around with it to fully understand why it's so amazingly awesome. ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
Re: [Flashcoders] How to determine value of source code
Thank you all for replying. It really made things clearier and some of the points made I really didn't think of yet, for instance the code libs. I really didnt take the time to develop those into consideration. Seems like a hell of a job to value code, I prefer coding :0 Again thanks, Jiri Ian Thomas wrote: I'd be very careful how you proceed with this, but at the end of the day it's your own judgement. It also rather depends on how much of what you've written for the client is solely for that client - you will never reuse it - or if you're depending on code libraries you've previously developed and plan to continue on developing. With our projects, the price to develop the project is assuming our (extensive) code libraries already exist. So if a client asks for source code, I'll tend to quote them for the project development time + all the time to (re)develop all those libraries (and associated testing etc.). And I'll explain the reasons behind it.

Re: [Flashcoders] Decorator Pattern - removing a decorator
Steven,
thanks for that helpfull reply. It is funny becuase I was just thinking
about the dualism, on the one hand there are these wonderfull elegant
design patterns that supposed to make things easier and on the other
hand it seems like coding has just became harder ever since when I
started applying them. Knowing about them seems sometimes almost a
burden. But the absolute elegance of how they can be used, which is
reflected in the many articles and books on them, just makes me want to
understand them better. And as you say, applying them and failing
horribly is a perfect way to get to know their individual intrisic workings.
Strategy is the one that I am just now looking into, because the
Decorator and the possibilty of not removing them just doesnt make them
suitable for the behaviour I was after on that level.
I have something like this now.
var item = new Item()
item.executeModifier() {
modifier.execute(item.mc)
}
item.setModifier(modifier) this.modifier = modifier
item.setClip(mc) this.mc = mc
Then I will use the Decorator pattern, for decorating (what else) the
items. It so happens that some Items contain text that can be edited.
class ItemTextDecorator implements itemInterface{
_item:Iteminterface
function ItemTextDecorator(item:Iteminterface)
{
_item = item
}
function executeModifier() {
_item.executeModifier(_item.mc)
}
function setModifier(modifier) {
_item.setModifier(modifier)
}
function.setClip(mc) this.mc = mc
//additional function to set Text and edit text
}
It feels beautiful to piece things together like this :)

When will it end, if ever?
"What you're experiencing is premature enlightenment." - Tyler Durden
The Gang of Four specifically warns about this, and it's important to
acknowledge that it's happening.
When people first learn about design patterns, they will immediately
begin looking for places to apply them. They will do this and fail in
some particular way, and in doing so, learn more about that design
pattern or perhaps one that they don't know of, yet. The issue most
people have is trying to solve a problem with a design pattern they just
learned without understanding that it isn't an appropriate pattern.
But, you have to do it wrong in order to learn why. Prepare to fail and
learn from those failures. It will make you a better coder.
Your initial hunch is that your problem would best be solved by the
Decorator pattern, but it very well may not be. The Decorator pattern
has fallen out of favor in recent years, as many people believe it
violates good OOP practices. It has its uses, but they're limited.
You should continue coding this using Decorator if you like, so you can
discover what its limitations are. It sounds like you're already
hitting them. It's possible that Strategy and Composition might be
useful here, as well. Just understand that you won't understand until
you code yourself into a corner a few times. :)

Re: [Flashcoders] Decorator Pattern - removing a decorator
Meinte, i have been doing that for the last 4 years and I am not saying you are wrong, but I get the feeling that I am reinventing the wheel every time. Why not use patterns that have been developed over the last n years and as a result get better maintainable code. I just dont have that god given gift/talent or education that I can just code and discover that I used a pattern. And how can I discover I used a pattern, if I dont know them that well yet. So maybe your right, but personally I dont think it will cut the cake for me, if I want to develop myself as a better programmer and be able to start delivering code that is easy for other programmers to recognize. Am I living in a dream? I am still looking for some feedback about my last post, do you wanna give it a go?

Re: [Flashcoders] Question on garbage collection
Erik,
thanks for clearing that up for me. In retrospect it makes sense that
the memory builds up with the trace statement. From now on I will test
for memory leak in the standalone player.

That all looks fine. There is no memory leak in the code you showed here.
You do not need to delete tTime as it is declared within the scope of the
function and will be marked for deletion as soon as the function is
complete.
If I run the classes (with the line clockdata = new
ClockData() commented out), the memory is stable in the stand alone
player. In flash the memory is slowly going up, but that is because we
are doing a trace each interval.
Note that it takes a few seconds for the memory to be stable.

Re: [Flashcoders] Question on garbage collection
Erik,
it would be something like this:
var c:Clock = new Clock();
getTime()
setInterval(this , 'getTime' , 1000)
function getTime()
{
var tTime:Time = c.getElepasedTime()
trace(tTime.serialize())
delete tTime; // is this neccessary and if so, is tTime = null maybe
better ???

Re: [Flashcoders] Isometic game - zdepth managing for multiple movable characters
Thanks everybody for their explanation. I am going to try to implement the z-depth manager as discussed. Jiri Ian Thomas wrote: Hi Jiri, The key here is that you can have 'empty' depth levels i.e. an object at depth 5 and an object at depth 8 with nothing at depth 6 and 7. You can make the depth dependent on the actual pixel _y value of the object rather than on the y value of the tile - so depth=_y (or more likely depth=startDepth+_y, because you'll want things behind your objects - like the tiles). To handle multiple objects etc. - from memory, when I last did this I wrote a depth manager that did something like: - Reserve 100 'slots' per_ y-value (so you could have up to 100 objects sharing the same vertical position) - Assign a depth value that combines the y value with the first free slot number - so (something like) depth=startDepth+y*100+freeSlotNumberForThisYValue That's not exact, but you get the idea. That way, generally you just need to assign a depth to an object, you don't need to shuffle all the other objects around. IIRC, it worked rather well. Hope that's helpful. Ian On 9/11/07, Jiri Heitlager <[EMAIL PROTECTED]> wrote: He guys (and maybe girls), I have a question that is related to z-depth managing in an isometric game, that needs to be made in AS2. In the game I basically use one abstract layer that holds all the tiles and their information wheter or not a movable object is allowed to 'walk' over the tile. Then there is another layer that holds all the objects, so that includes a player, a computer controlled player and enviormental objects that players cannot walk through being the visualization of the first layer. Every object gets a z-depth assigned. For the players the zdpeth need to be set based on the tile they are at. This way the players can walk 'around' the enviorment objects. For the z-depth calculation I use the tile grid x and y plus the width of the row, this generates an unique z-depth number and makes sure that the higher the y, the bigger the z-depth , thus objects appear infront of objects with a lower y index. Here is the problem I am trying to figure out. If two movable objects, or even three of them are at the same time on the same tile, then the above described z-depth managing will fail. How do I deal with that? Then another question I have is this. Does every movable object needs to check/swap z-depth on every frame. Wouldn't that be to CPU intensive? I really hope someone can clear this up for me. thank you in advance, Jiri ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

I'm not sure if I'm getting it right; but if you want to animate a

acessible (like data that is only acessible through methods and
functions.. gotoAndStop() to change a Movieclip's _currentFrame for
example).
If you want to tween a numeric property that's already acessible, you
can tween it directly, with no special property, wrapping function, or
anything. Ie:
Tweener.addTween(this, {x:10, time:.5});

Hi Jiri,
I've pasted below the isometric class that I wrote
for one of my game books.
It is a handy class that allows for easy translation
between screen coords,
and iso coords. In addition, it handles tile-based
dept calculations as
well. You asked how do you handle multiple per tile
- check out the leeway
variable in this class. If leeway is set to 5, and
calculateDepth returns
1230, then you can place your item anywhere from
1230 to 1235. You just have
to keep track of which depth is being used.
You don't have to swap depths of every item every
frame. You just have to
swap depths on any items that has just changed
tiles.
There are two limitations with this technique:
1) It does the depth calculations based on the size
of the map. For most
uses this is fine. But if your map is like 5000 X
5000 tiles, then this
depth calculation can probably quickly get too high
for Flash to handle
without further modifications.
2) A sortable item needs to be no bigger than a
tile. If the base of this
item takes up multiple tiles (like a couch, or
bench, etc) then you need to
either slice it up into tile-sized pieces, or change
the depth approach. The
approach that you use if you are not slicing it up
does require resorting
lots of item depths frequently rather than using
just using unique depths
per tile.

Subject: [Flashcoders] Isometic game - zdepth
managing for multiple
movablecharacters
He guys (and maybe girls),
I have a question that is related to z-depth
managing in an isometric
game, that needs to be made in AS2.
In the game I basically use one abstract layer
that holds all the tiles
and their information wheter or not a movable
object is allowed to 'walk'
over the tile. Then there is another layer that
holds all the objects, so
that includes a player, a computer controlled
player and enviormental
objects that players cannot walk through being the
visualization of the
first layer.
Every object gets a z-depth assigned. For the
players the zdpeth need to
be set based on the tile they are at. This way the
players can walk
'around' the enviorment objects. For the z-depth
calculation I use the
tile grid x and y plus the width of the row, this
generates an unique
z-depth number and makes sure that the higher the
y, the bigger the
z-depth , thus objects appear infront of objects
with a lower y index.
Here is the problem I am trying to figure out. If
two movable objects, or
even three of them are at the same time on the
same tile, then the above
described z-depth managing will fail. How do I
deal with that?
Then another question I have is this. Does every
movable object needs to
check/swap z-depth on every frame. Wouldn't that
be to CPU intensive?
I really hope someone can clear this up for me.
thank you in advance
Re: [Flashcoders] Isometic game - zdepth managing for multiple movablecharacters
First off, thanks that you people took the time to help me out and thank you Jobe for sending me your class. I appreciate that, but would really like to program the game myself from scratch to get a full understanding on how games like this are made. I am reading all the replies and trying to see if I am understand them correctly. Basically I have two options. Give every movable object the depth of the screen _y value and make sure that objects can never be on the same _y position. Second option. If the movable objects only move one tile at a time, meaning that their screen _y position could sometimes be the same, I need to assign for every tile a range of n numbers of depth that can be taken. Then check for an available depth within each tiles indivudual range of depth , when a movable objects is on a tile. @Danny, could please explain your comment on subsorting a bit more. I am not quit sure if I understand it. > However, you can optimise quite a bit > by sub-sorting - if you know that object 1 is in the rear 16 tiles and > object 2 is in the front 16 tiles, no need to check the z-order.

How do I deal with that? If this is possible in your game then you'll need to either store sub-tile positions and z-sort further on those (you could, for example, assign ten z-slots per tile to ensure that you have more space) or randomly choose one to be in front of the other (if there's only one position per tile, then it doesn't matter which one gets drawn in front). Then another question I have is this. Does every movable object needs to check/swap z-depth on every frame. Wouldn't that be to CPU intensive? Depends how you do it. If there's only a few movable objects, this shouldn't be particularly hard on the machine - Flash isn't the fastest thing in the world, but it's fast enough for that. However, you can optimise quite a bit by sub-sorting - if you know that object 1 is in the rear 16 tiles and object 2 is in the front 16 tiles, no need to check the z-order.

Re: [Flashcoders] search engine optimization for flash sites
Robin, maybe this will help. It wont solve all your problems, but could make a solution a bit easier. http://www.asual.com/swfaddress/ Jiri Robin Burrer wrote: Hi there, My client wants to have his website optimized for search engines. I don't know much about this topic. The binary data of a flash file can't obviously be read by a search engine though. I have this idea to create a html site map for my flash page. Basically this site map would have short summaries of all flash pages and links to these pages (e.g. http://myDomain.com/myflashPgae.htm?page =home). The search engines should then be able to find the site map page. Ideally this site page would be generated dynamically. But for now a static page will do. Does anybody have experience with such an approach? Any thoughts?

[Flashcoders] Iterator question
Hello list,
i have a page object that contains has a Array that holds pageElements.
This is a storage for elements with an iPageElement interface.
The page object has an destroy() method. When page.destroy() is called,
it will loop trough the page.pageElements Array using an iterator. Every
iPageElement broadcasts an onElementKilled message when is has been
destroyed. When a pageElement broadcast this message, the page need to
continue in deleting the next element in the page.pageElement Array.
The callback method onElementKilled in the page instance, searches for
the element that has been deleted and then removes it from the
page.pageElements Array. This is where i think a problem rises, because
if the page.pageElements array is updated during the process, the index
does not match the element to remove anymore. How can I solve this
potential risk?
Another question, the array that is passes into the iterator is a
reference to the pageElements Array. Does this mean, that if I delete an
element from this array from within the iterator, the page.pageElements
array is modified?
I hope my question is clear..
thank you in advance.
Jiri
Below a snippet:
private function getPageElementIterator() : Void
{
return new PageElementIterator(this.pageElements)
}
//initiated the deleting proces, by starting with the first element.
public function destroyPageElements() : Void
{
destroyElement(this.pageElements[0]);
}
private function destroyElement(element:iPageElement) : Void
{
curElement.addEventListener('onElementKilled' , this)
curElement.destroy();
}
private function onElementKilled(eventObj:Object) : Void
{
var killElement:iPageElement = eventObj.target;
var iter:PageElementIterator = this.getPageElementIterator();
while(iter.hasNext()){
var curElement:iPage = iPage (iter.next());
if(killElement == curElement) {
//deleted the element now clear the listener
and continue
killElement.removeEventListener('onElementKilled' , this)
/*
* POTENTIAL RISK, if a new element is added, then the index, does
not match the right element anymore
*
* get the current index from the deleted
element by checking what
* the currentIndex of the iterator is, and remove it from
this.pageElements Array
*/
this.pageElements = this.pageElements.splice((iter.getCurrentIndex()
, 0)
//get the next element in the iterator array
if(iter.hasNext()) this.destroyElement(
iPage(iter.next()) );
delete killedElement;
break;
}
}
}
if(this.pageElements.length == 0){
trace('all page elements have been removed')

[Flashcoders] Colin Moock Book - stores in Berlin
Hello, My question has not so much to do with actual coding, so I hope that it is not a problem posting it here. I am currently living in Berlin for a few months and I am looking for a bookstore where I can buy the new Colin Moock book on AS3. If somebody on the list happens to be living in Berlin and knows a shop where I can buy books on computer programming (especially the Moock Book), I would love to know it ? And yes I am aware of amazon and the lot, but I prefer looking into books before buying them ;) Jiri ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
Re: AW: [Flashcoders] Turn image around effect?
Hmmm, i would also really like to know how they did that. It seems to be running in as2 FP8, so that probably rules out papervision. Maybe it is done by Sandt, but I cant figure out how.

[Flashcoders] Preloading mp3 - onLoad vs GetBytesLoaded()
Hello list, I have a question on preloading mp3's. When I start preloading the mp3 I set the isstreaming to false. Then I check the bytesloaded compared to bytestotal en when that is 100% procent it means all is loaded When I start preloading the sound, I also delegate the function onLoad of the sound Object. I put a trace inside this delegated onLoad method and that fires much later after the 100% loaded is fired? I noticed that when the mp3 is 100% loaded according to the BytesLoaded, and I start the sound by creating a new sound object and using the same url as the preloaded mp3, but setting the streaming flag to true, it stills takes some time, as it seems to buffer the sound. Shouldn't is start immediatedly, as it was preloaded before and is resisiding in the browser cache? How is this possible and what is the best way then to preload a mp3.

Re: [Flashcoders] Grid / Math - getting neighbouring positions
Thxn Joshua and others,
I have to look into that. In the mean time I came up with the following
code. This takes in a vector and then calculates a 'ring' from that
position. With this, I can scale up the 'radius' and get recursively get
all the rings from a point from in to outer ring. My goal i still to
fill an array with all the points of the grid, starting from a center
point en then moving outwards in a ring.
Here is the code so far, i hope someone can maybe give some commment on it.

This requires you to re-do your grid, but it's one way to handle it
without complex math. It seems a simple way would be to make each row of
the grid an array (the entire thing can be an array as well, but make
each row it's own array). You could do some object mix-in to ease
syntax and allow for storing complex data types:
myGrid = {row:[{cell:[{id:0},{id:1},{id:2},{id:3}], id:0},
{cell:[{id:0},{id:1},{id:2},{id:3}], id:1},
{cell:[{id:0},{id:1},{id:2},{id:3}], id:2},
{cell:[{id:0},{id:1},{id:2},{id:3}], id:3}]}
(you would make that with for-loops, not necessarily hand-type, though
you could)
So the cell at position 3,2 would be: myGrid.row[2].cell[1] (since
arrays start at 0)
So to get surrounding cells of myGrid.row[2].cell[1], it would be:
myGrid.row[1].cell[0]
myGrid.row[1].cell[1]
myGrid.row[1].cell[2]
myGrid.row[2].cell[0]
myGrid.row[2].cell[2]
myGrid.row[3].cell[0]
myGrid.row[3].cell[1]
myGrid.row[3].cell[2]
In other words, for the cell up and to the left of the current cell, it
would be:
myGrid.row[thisRow.id-1].cell[thisCell.id-1]
the grid cell directly above would be:
myGrid.row[thisRow.id-1].cell[thisCell.id]
the grid cell directly above and to the right would be:
myGrid.row[thisRow.id-1].cell[thisCell.id+1]
the grid cell directly to the left would be:
myGrid.row[thisRow.id].cell[thisCell.id-1]
etc.
get thisRow and thisCell objects with for loops.

Re: [Flashcoders] Grid / Math - getting neighbouring positions
The ring is defined by distance not by connectedness. It is used for the following. A big image will be split into tiles of 100x100 pixels, that are loaded from a server. The total image made of these tiles are loaded in a movieclip so that the image is rebuilded. The image is masked by a 100x100 mask and can be scrolled to left and right. Based on the tile that is in the view, i would like to preload the rest of the tiles 'intelligently'. To do this, i take the current tile and start building a loadingQue Array from there. So first the ring around the current tile, the a ring around the first ring and so on, until all the tiles of the total image are in the array. Does that make sense?

[Flashcoders] Mathematics specialist - trigonometry
Hello list, I have a client that wants something like this: http://www.wdcs.co.uk/media/flash/whalebanner/content_pub_en.html Basically a huge image is split into tiles, and each load a tileImage. The user can drag a navigator (small view in ratio) over the image. It can occur that the tiles under the view are not loaded yet. To deal with this I need to know wich tiles are visable, after the user has moved the navigator and then load the corresponding image in at the position. Becuase the amount of tiles, can become quit big I dont want to loop through all the tile MovieClips to find out the closestby. I have a feeling trignomotry is the way to ga, but am poor in Mathmatics. In my example you will find a image with 100x100 movieclip tiles. This is just for testing, because in the end I would like to dynamically createMovieClips on there right location. So I actually need to find out locations [x,y] that are visible. I uploaded some files and hope someone will take the time to dowlaod them and help me with finding a solution. Here is a view: http://playground.dadata.org/trig/test_01.swf and here the .fla can be downloaded http://playground.dadata.org/trig/test_01.fla Many thnx Jiri ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
[Flashcoders] SWX and security
I have been reading up on SWX by Aral Balkan and have a question that maybe the list can answer. Dealing with sending data to a server from flash there is always the question of security. Making games in flash and sending data to a server is always a hassle when the sended data needs to be obscured. I wonder if SWX has the potential to make sending data over the wire 'saver', that is when the swf is created on the server side, maybe it can be encrypted. But still the URL to the gateway on the server can be read with different tool, so that makes me wonder if it is possible at all. Some thoughts on the matter by the more genious among the list would be nice ;) Jiri ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com

Re: [Flashcoders] Init generic clip
Thnks for the posts
Both suggested solutions don't work, altough the first one by Gilles
does work. But I want the button to be selfcontained, no external
initFunctions. Just a MovieClip onStage called btn and on the parent
timeline of btn something like
btn.setLabel('hello world')
The onLoad suggestion I dont get working.
btn.onLoad = function(){
this.setLabel('hello world')
}
this is actual the same as the onEnterFrame. It is not that I have a
problem with the onEnterFrame, I just dont understand how Flash VM
works. Basically I would like the enclosed script to be executed before
the frame of the timeline it is seen on is started. Is this possible.
For more light on what I am trying to achive, the file can be downloaded
here:

Hello list,
I have made a very simpele MovieClip that functions as a generic button,
this is clip 'gen_btn_mc'.
For the designers it is important that I place the gen_btn_mc on stage
and not attach it at runtime. The gen_btn_mc clip itself has a few
functions on the 1st frame of its timeline, these are:
setLabel()
setSize()
setIcon()
Because the button is place on stage during authortime, it seems the
functions of the gen_btn_mc can only be called after one 'onEnterFrame'
because it seems the functions are 'undefined' otherwise.
EXAMPLE
clipInstance0 is set on stage timeline. Then on the stage timeline I
have to put this code.
onEnterFrame = function(){
clipInstance0.setLabel('hello world')
clipInstance0.setSize(200)
clipInstance0.setIcon(true)
delete this.onEnterFrame
}
This makes the clip flicker, and it is clearly being set, becuase of the
one onEnterFrame loop.
QUESTION
Is there a way I can overcome this init. problem WITHOUT attaching the
clip at runtime?
Many thanks.

[Flashcoders] saving bmp from flash
I am looking for a way to capture webcam images from Flash and save them as .bmp's. Using PHP is not a possibilty because it cannot save images as a .bmp. Is it in theory possible to use screenweaver. So in Flash I would run trough all the pixels getting there value and store these values in an Array. Then use screenweaver to save the array to a file. But how do I build an .bmp then. Would this be possible to save a bmp from flash or does someone knows a solution using php. Thank you in advance.
