[Flashcoders] Path/Point interpolator

2010-10-27 Thread Jiri

hello,

I have an array of points that define a path. I would like to 
interpolate the complete path, so that I can move an object along that 
path based on a position.
So for instance when I tell the interpolator to move to postion .5 it 
would be in the middle of the path, based offcourse of the interpolator 
step/interval size.


for instance:

interpolator.interval = 3 pixels;
interpolator.getPositionAt(.5) // would be the middle position.

The solution I am after is that I dont want to precalculate all the 
positions up front, I would like to calulcate the position 'on the fly' 
so to say.


Could someone give me a hint on how to tackle this.

Much appreciated.

Jiri

Re: [Flashcoders] Embedding Fonts, it should be easy...., right!

2010-09-15 Thread Jiri

He Keith,

thanks for pointing that out to me. I tried and it still wont show any text.

When I enumerate the fonts, and using the code provided by Keith I get 
this output


embeddedFonts   Array (@367abf39)   
[0] flash.text.Font (@369a56c1) 
fontNameMyriadProFont   
fontStyle   regular 
fontTypeembedded
[1] flash.text.Font (@369a5701) 
fontNameMyriadProBoldFont   
fontStyle   bold
fontTypeembedded
[2] flash.text.Font (@369a5761) 
fontNameMyriadProFont   
fontStyle   bold
fontTypeembedded
[3] flash.text.Font (@369a57a1) 
fontNameMyriadProRegularFont
fontStyle   regular 
fontTypeembedded
length  4   

So although regsitering two fonts to the Font class, it shows 4 Font 
instances in the embeddedFonts??


Anybody has another take?

[Flashcoders] Embedding Fonts, it should be easy...., right!

2010-09-14 Thread Jiri

Hello,

i am really getting headache from Embedded font stuff in as3 and would 
like some help.


I embedded the fonts by using the Embed tag:
code
[Embed( source='../../../../../fonts/myriad 
pro/MyriadPro-Bold.otf',
fontName='MyriadProFont', unicodeRange='U+0010-U+00FC', fontWeight = 
'bold',

fontFamily=Myriad Pro,
mimeType='application/x-font-truetype',
embedAsCFF=false
)]

public static var MyriadProBoldFont:Class;

[Embed( source='../../../../../fonts/myriad 
pro/MyriadPro-Regular.otf',
fontName='MyriadProFont', unicodeRange='U+0010-U+00FC', fontWeight 
= 'normal',			

fontFamily=Myriad Pro,
mimeType='application/x-font-truetype',
embedAsCFF=false
)]

public static var MyriadProRegularFont:Class;
/code

When I created a new TextField and setup the textformat to use the 
MyriadProFont and add it to the list all works fine.


Using this snippet I checked to see if the font is really registered 
and it is.			

code
var embeddedFonts:Array = Font.enumerateFonts(false);
embeddedFonts.sortOn(fontName, Array.CASEINSENSITIVE);
/code

Now we also have swf's that gets loaded in. The designer has put 
textfields in place. I need add the textformat to it. But the damn 
embedding doesn work. It doesnt render any text. I searched but could 
not find any solution. I hope someone here has a solution. Below the 
code i use.



code
var tField:TextField = _sprite.getChildByName(field) as TextField;
addFormatting( treatmentTimeInfo , STD_LABEL_FONT_SIZE , WHITE);

function addFormatting(tField:TextField):void{

var format:TextFormat = new TextFormat()
format.font = Myriad Pro;
format.bold = true;

tField.defaultTextFormat = format;
tField.embedFonts   = true;
tField.setTextFormat( format );

tField.text = some_text
}

[Flashcoders] Question FP10 inactive event dispatched when not visible.

2010-08-17 Thread Jiri
I was reading some where that FP 10 now drops the framerate and pause 
any loading activities when it looses browser focus in the case of 
browser tab changing. I can't seem to find the article anymore, but I am 
wondering if there is also an event being dispatched when FP goes into 
'hybernation'.


Does somebody know if that is done, or could point me to an article 
describing this behaviour

[Flashcoders] Could this be done more elegant.

2010-08-13 Thread Jiri

Hello,

I wrote a routine that checks if the fps is below 45 fps for longer then 
20 ticks, I toggle the quality of the SWF. If it then after is greater 
then 45 fps for 20 ticks I toggle quality back up.


It works, but out of interested, I was wondering if this could be done 
in a other more cleaver way then I did. Looking at the routine it feels 
very 'big', because I use 3 external vars and quite some code.


var treshold:Number = 20;
var buffer:Number = treshold;
var addValue:int;
function doProfiling(e:Event):void{
if(fps=45){
addValue = 1
}else{
addValue = -1
}
buffer+=addValue
if(buffer  treshold) {
buffer = treshold;
}else if(buffer  -treshold) {
buffer = -treshold;
}else if(buffer == 0) adjustQuality()
}

Cheers,

Re: [Flashcoders] Could this be done more elegant.

2010-08-13 Thread Jiri
Thanx for the answer, I am on a project where the whole thing is 
allready set up. The quality is now set to BEST as soon as the FPS goes 
under 30 (i used 45 in my example), but on fast machine this results in 
very short graphical glitches, because it is usually only 1 or 2 frames 
where the FPS is below 30.
I wanted to prevent this and make the profiling a bit better. Not toggle 
all the time, but just wait a bit before doing the call.


So it is not so much about the execution based on EnterFrame but more on 
how to write the function a bit cleaner.

No it won't because of this line that calls a toggle function based on 
the current fps.

if(buffer == 0) adjustQuality()

function adjustQuality():void{
fps = (fps == 45) ? 20 : 45 
trace(qulaity is now adjusted to :  , fps )
}

This doesn't change the way it works, but you could rewrite the addValue

I have a simple question. I came across some code in a project that defines
a const in a function.

function doSomething():void{
const my_var:String = my_var

var buffer:String = '';

for(var i:int = 0 ; ilist.length ; i++){
buffer += list[i] + my_var

What is the difference compared to this:

[Flashcoders] Question on variable init in a for loop

I have the following case:

var l:Array = [{},{}]
function test():void{
for each(var i:Object in l){
var id:String;// = null;
trace(1 ,id);
id = test + Math.random().toString();
trace(2 ,id);
}
}

I seems that 'id' is not resetted to null on every iteration as I would 
expect. I have to explicitly set the id to null myself! Does some know 
why this is, or are my expectations just wrong.

[Flashcoders] JSFL question on shapes and strokes.

2010-06-01 Thread Jiri

Hello,

I am trying to convert some drawings on stage into a movieclip via jsfl.
It works when all the elements on stage are separatly grouped. JSFL 
doesnt seem to 'see' non grouped drawings  as seperate entities.


To clearify, I have on frame on the main timeline. In this frame I have 
three shapes that are grouped and two shapes that are just plain circles 
made of a stroke. So in total I have 5 entities on stage. The JSFL 
script below outputs just three times. Does anybody know how I can get 
all five shapes on stage via jsfl, no matter if the are grouped or just 
drawings? I want each item to be converted into a MovieClip.



var doc = fl.getDocumentDOM()
var tl = doc.getTimeline()
var layers = tl.layers;

tl.setSelectedLayers(0);

fl.outputPanel.clear();

for (var l=0; llayers.length; l++) {

var shapes = layers[l].frames[0].elements

for (var k=0; kshapes.length; k++) {

doc.selectNone();

var shape = shapes[k];

shape.selected = true;

fl.trace('selected = '+shape);

shape.selected = false;

}

[Flashcoders] Strange RegExp behaviour

2010-03-18 Thread Jiri

Hello,

i would like some help, because I am confused.

If have a Movieclip that holds several sprites some of them have 
instance names like so

frame_n where n is a number.

I then loop through every child of the MovieClip and test the instance 
name using regExp.


var childs:int = clip.numChildren-1;
var pat:RegExp = /_[0-9]+$/ig;

while(childs = 0){
var instance:DisplayObject = clip.getChildAt( childs );

if( pat.test(instance.name) ){  
Logger.debug( info box frame , instance.name );
}   
childs--
}

I have three movieclips called 'frame_0' , 'frame_1' and 'frame_2'  for 
sure, but it when I run the above code, it only show 1 and 0??


Anybody has an idea?

[Flashcoders] bitwise question

When i have a 8 bit int where only one of the bit can be 1, what is then 
the quickest way to get that bit position with value 1?

Now I use this.

function getBit():int{
var tCount:int = 0;
for (var i:int=0; i  8; i++) {
  if (8  (1  i))   return i;
}
return 0;

Can this be done faster?

Yes. Use a lookup table;

var lookup:Array=[];
for (var n:int=0; n128;n++)
{
   lookup.push(0);
}
lookup[2]=1;
lookup[4]=2;
lookup[8]=4;
//etc..

function getBit(n:int):int{
   return lookup[n];
}

LOL, better still, just ditch the function altogether and use 
lookup[somevariable] directly.


I might as well comment that this is lean and mean without any safety 
net to make sure the int is in range and indeed has only one bit set.

Re: [Flashcoders] bitwise question

2009-09-15 Thread Jiri
Can't confirm your findings right now, and also wonder which loop you 
are talking about. My initially posted one?


 function getBit():int{
 var tCount:int = 0;
 for (var i:int=0; i  8; i++) {
   if (8  (1  i))return i;
 }
 return 0;
 }

or the one suggested by John McCormack. I cant remember have faulty 
result with my loop because like Glen Pike mentioned the i is used for 
the shifting.


Also the 8bit to test will always only have one bit set to 1. Which 
could be a potential dangerous assumption i guess.

 0001
 0010
 0100
etc..

Will do testing tomorrow.

The only thing that might be faster is using i-- rather than i++ - for 
some reason decrementing through a loop is suppsoed to be faster.

Jiri,

I haven't done much bit twiddling yet in AS3 but I think you were 
fast already, but your i was being incremented and shifted.

Also i8 would only get you bits 2,1,0
In binary that would be i1000
How about:

function getBit(var numb:int):int {
 var bit:int=1;
 var count:int=0;

 if (numb==0 || numb0x80) return -1; // error

 while (bit  numb == 0) {
   1  bit;
   count++;

Now I use this.

function getBit():int{

for (var i:int=0; i  8; i++) {
  if (8  (1  i))return i;
}
return 0;

Can this be done faster?

[Flashcoders] Syntax coloring Eclipse

2009-08-21 Thread Jiri
I am forced to use eclipse, but i am used to work with a black 
background. I changed the syntax coloring in the eclipse preferences to 
match my preferences, but the symbols  . ,  ect.. are all black and 
there is not an option provided to changes there color.


If you look at the Java syntax coloring options they are much more refined.

I am looking into the FlexBuilder app root directory now to see if i can 
find the xml file that is defining the colors, which i cannot find.


Does anyone know how i can find it, what to look for or how to deal with 
the super annoying thing that should be provided in any decent

[Flashcoders] Question on preventing this array[n] = 'whatever' on Array var

2009-07-14 Thread Jiri

Hello list,

Lets say I have a class with a public getter to a private var which 
holds an Array.

Some other class can do this then:

var tArr:Array = class.myArray;

I can then do this:
tArr.push(int) and the content of the array has changed without the 
class knowing. This is in most cases I use it ok, but now I am wondering 
how to deal with it when I really want to create a read only array.


I am aware that I can copy it, but then this can be very expensive when 
it is requested a lot of times and it is a relative big array.


So i was thinking the following.

class A{
private var pArray:Array = [1,2,3]

public function get list():listArray{
return new listArray(pArray);
}

}

class listArray{

private var pList:Array
public function listArray(tArr:Array):void{
pList = listArray
}

override function push():void{
throw new IllegalOperationError()
}

}

I would have to override all the public methods of Array which can be a 
pain.


My question is.
How would I prevent users from doing this:
listArray[n] = 'whatever'


Much appreciated

Re: [Flashcoders] Question on preventing this array[n] = 'whatever' on Array var

2009-07-14 Thread Jiri
Thanx. Well i could extend Array and then override all the methods and 
have them dispatch events, like ON_CHANGE.

Overwriting all the public mehtods is a pain, so I suspect i can use the
flash.utils.Proxy for  this.
I just need to understand this utils.Proxy and flash_proxy thing.

Could somebody hint me if this would be worth looking into for this 
particular case?

Glen Pike wrote:

Sounds like you want to use a kind of Observer pattern:

Can you wrap up your array class in something that implements the 
methods you want, ignores / passes on the stuff you care about and then 
notifiies listeners of any changes that you care about?


Flex makes this quite easy with {watching} objects virtually 
automatically - not sure if there is something in PureAS3 that would 
help without requiring some huge framework.


The safest way of doing this though might be to prevent any external 
class accessing your array.  Make your class implement some kind of 
ArrayInterface and allow the calling classes to use your class rather 
than your array to add and remove things?

I've read though the documentation regarding event bubbling several 
times, but the concept remains blurry.  Perhaps this example will help

I want to display a custom cursor, a version of the Photoshop flat

that it can be moved around within the frame.  So, I have for the sprite 
of the image,  MOUSE_OVER turns on and MOUSE_OUT turns off the custom 
cursor.  The custom cursor object simply hides or displays the Mouse and 
has a sprite on the top level of the stage with startDrag() and stopDrag().


The problem is that as soon as the custom cursor's sprite becomes 
visible, it causes a MOUSE_OUT event to get called on the image (because 
the image is intercepting the mouse-over?) and then the custom cursor 
gets turned off again.  The result is a flashing cursor.  Nice effect, 
but not what I have in mind.


Thanks in advance for any guidance!

[Flashcoders] When to use flash.util.proxy

2009-06-30 Thread Jiri

Hello list,

i am reading up on the flash.util.Proxy class and I came across this post:
http://www.onflex.org/ted/2006/04/magic-with-flashutilproxy.php


The author mentions this:
..Using Proxy is best reserved for situations when you want very fine 
grained control of behavior. The are very useful for dynamic method 
calls, like WebServices, Remoting, or in general creating a Facade for 
any type of object...


I dont really understand the remark and was wondering if someone could 
explain it to me.


I am trying to figure out when the usage of this proxy would be handy.

What is the difference with using normal getters and setters?
Could somebody tell me of a case where he/she used this flash.util.proxy?

[Flashcoders] gzipped xml receiving with flash

2009-06-25 Thread Jiri

Hello list,

Would it be possible to have a apache server return a gzipped version of 
xml (using the mod_deflate) and then uncompress the gzipped file in as3.


I guess that the BrowserMatch inside the httpd.conf would need to be set 
to a HTTP request comming from the flash player.


Would it possible for the flash player to mimick a call made directly 
from a browser? So that the apache returns an actuall gzipped version.


If it could be possible, how would this then be handled inside flash. I 
reckon the loader would need to load the file as a BINARY and then a 
gzip parser would deal with it?


I know AMF would work for what i want, or have the server preprocess the 
 files into a .zip. But i was just wondering and curious.


As my questions probably reveal, i am not an expert in this area, so 
excuse me if my questions are really naive.

[Flashcoders] Determining probablity of a random pick.

Hello list,

return tXMLSource.nodes[tRandom]
/code

Now i would like to change it, so that I can specify a weight to each

selected out when a random pick is being performed.


Does anybody know how to build such an algorithm?

Do you mean that this;

c weight=2

First calculated the range for each node.
A = 0 - 5
B = 6 - 7
C = 8 - 10

Then store in an array like so?
Array[0-5] = A
Array[6-7] = B
Array[8-10] = C

Last step get a random number between 0 - 10 = for instance 5

//result is then
return Array[5] as XML


If this is what you mean, would this approach not take a 'relatively'

Sum all of the node weights, then generate a random number within that 
range.


Now you have to find the node corresponding to that number. This can be 
done by traversing the nodes in sequence. As you traverse the nodes sum 
the weight until the value generated is within the range - then you have 
the right node.


You can optimise this by using an array of pointers, or keeping the 
weights in an external array, but that may be more or less interesting 
depending on the number of nodes involved and what optimisation you need.

You don't have to store the node itself, just a reference to it, so no 
it wouldn't be a memory hog. It could even just be the numerical index 
of the node.

For example:

var tXML:XML = new XML(
dataimage_conf
  randomImage id=1 delete=true/
  randomImage id=2 delete=true/
  randomImage id=3 /
  randomImage id=4/
/image_conf/data)

var pXML:XMLList = tXML.image_conf;

When i then use this:

delete pXML.randomImage.(attribute(delete) == true)[0]

Not all the nodes with @delete = 'true' are removed.

trace(pXML.toXMLString())
// this is what is the output looks like
image_conf
  randomImage id=2 delete=true/
  randomImage id=3/
  randomImage id=4/

  randomImage id=4/
/image_conf/data)

var pXML:XMLList = tXML.image_conf;

When i then use this:

delete pXML.randomImage.(attribute(delete) == true)[0]

Not all the nodes with @delete = 'true' are removed.

trace(pXML.toXMLString())
// this is what is the output looks like
image_conf
  randomImage id=2 delete=true/
  randomImage id=3/
  randomImage id=4/
/image_conf


Much appreciated.

[Flashcoders] SmartyPants IOC

2009-05-04 Thread Jiri

Hello,

is there anybody on this list that has been using the SmartyPants, a 
dependency injection framework. I am curious to hear their experience 
with it. The documentation is _very_ limited, unfortunatly, and I am 
having a hard time getting my head around it.

Re: [Flashcoders] Conditional statement in [Embed(source=... tag

2009-04-29 Thread Jiri

So, you could do something like this in an embed tag

[Embed(source=Arial-Rounded-MT-Bold.ttf,
 fontFamily=ArialRoundedBold, fontWeight=bold, 
mimeType=application/x-font-truetype,

 unicodeRange=getCodeRange()]

Will try it.

Cheers for replying.

Sidney de Koning wrote:

Hi Jiri,

Why do you want to do that conditional there? Cant you call a var?
Then in your main entry class you set that var depending on the lang you 
get in.

Idea?

Or if you work with some sort of MVC ( Model View Controller ) 
architecture you could do that conditional in your Model and in your 
Emdbed tag just query MainModel.getUnicodeRange() which returns a string 
of all appropriate unicode chars.


Let me know if this works,

Sid

unicodeRange=((lang==id)? U+0020-U+017E,U+20A0-U+20CF :  
U+0020-U+017E)


Is this possible, or do I need to write a pre parser,  generating the 
.as file with the correct unicodeRange for a specific language. Then 
compile all the .as files for each individual country?

[Flashcoders] mxmlc include classes , possible???

2009-04-29 Thread Jiri

Hello list,

Is it possible to force the mxmlc compiler to include certain classes so 
they can be instantiated at runtime. So I dont have to put an explicit 
reference in the .as files, in order to include it.


I thought there was a compiler flag called include-classes, but a google 
search yields nothing of any use.


I tried putting this in my flex-config

include-classes
classorg.name.class/class
/include-classes

But I get an error.

Doing a mxmlc -help advanced in the console also yields no such flag.

So I wonder now, is it at all possible, or do i need to create a .swc 
and have that add to the librart tag?

the question is. I want to tween a clip its color to a certain hex Value.

So the equivalent of this in TweenLite:
TweenLite.to(mc, 1, {tint:0xff9900});

Thanks everybody, I am aware of all these other tween packages, but I am 
exploring GTween at the moment.
So it is not so much a question of how to tween color with a Tween 
Package, but more how to do it with GTween, because Google was not 
showing me any results on that.


I geuss not so many people are using GTween, especially not for color

Re: [Flashcoders] Bitwise selection

2009-04-03 Thread Jiri

So each element in a ByteArray can hold 8 bits.
What about the readInt() method of the ByteArray, does an integer then 
span over 4 elements of the bytearray. And if I start at position 0 and 
then call the readInt(), is the position after that then 4?

Thanks, Jiri.

One other thing worth mentioning is that an integer is actually 4 bytes, so
you have 32 bits. I kept my example to one byte for simplicity. If you want
to do operations on a single byte, you can use ByteArray elements.

Other bitwise operators to check out are XOR (exclusive OR, which means one
or the other is on, but not both) and shift operators  and  to check the
value of a particular bit.

Cordially,

var CHAR_ONLY:int = 4;

var RESTRICTION:int =  NUM_ONLY ;

function getRestrict():String{
var tRestrict:String = '';

Thanks Hans,

I am aware of that, so if-else would be the only way to go I guess.

Jiri,

if() isn't too bad, especially since you will possibly want to permit
multiple restrictions (like numbers /and/ letters, or Latin letters
plus umlauts). If you use if() and combine that with appending to the
restriction instead of setting it (+= instead of =), you gain
flexibility. That way, you could also split lower case and upper case
letter restrictions, and introduce a case insensitive restriction that
is set to (UPPER_CASE | LOWER_CASE) -- it would have both bits set, so
it would hit for both tests and append the restrictions to the a-z
A-Z  you already have now. That's just one example, the idea is not
to have a fixed number of selections, but groups that you can switch
on bit by bit, plus some predefined combinations (like the case
insensitive letter example) for convenience.

Also, don't test (restriction  2), but (restriction  NUM_ONLY). That
way, it's more readable, and you don't have to change all 2s if you
decide to reorder your flags. Even more pedantic :), test
((restriction  NUM_ONLY) == NUM_ONLY) so you don't run into problems
if you want to have flags that have multiple bits set later on.

 HTH,
Mark

Jiri has gotten some good answers. I got to work late today after working
until 11:30 last night meeting my 5:00 deadline :-P

 


I did occur to me that a fair number of us may not completely grok bitwise
stuff. That's computer science stuff, and a lot of us got here by other
routes-I see a lot of C programmers doing bitwise stuff, but relatively few
AS programmers (at least, we don't talk about it a lot). Still, it can be
blazingly fast, so when you have a need for speed, they are great.

 


So I thought I'd talk a little about bit operations. If you already
understand them, no need to read further (unless you wish to check my
accuracy).

 


First, the basics. We all probably know this, but a byte is no more than a
series of on-off switches, or bits--eight of them on most modern computers.
On is represented by 1, off by 0. So, a byte with every other bit on would
be 10101010.

 


When you do a bitwise operation, you are comparing bits. The bitwise OR
operator, | , compares bits. If either of them is on (1), the result is 1.
If both are off (0), the result is 0. Consider the following:

 


120 | 96

 


Compares 10101010 and 0110, giving the result 11101010 (234 decimal).
Visually, this may help:

 


10101010

0110



 

11101010 

 


We get that result because the | operator compares each bit. If either of
them is on, the result is 1 for that bit.

 


The AND operator  is similar in that it compares bit by bit, but both bits
have to be on to get a 1 result. Comparing the same two numbers as before,
120  96, gives you the result 0010, or 32 decimal.

 


10101010

0110



 

00101010 

 


Sometimes we use these as flags, where every bit can represent a Boolean
value. They also can be used for fast math operations (check out
http://lab.polygonal.de/2007/05/10/bitwise-gems-fast-integer-math/

 


This barely scratches the surface of bitwise operators and their power, but
I hope it intrigues some of you enough to pursue it further.

 


Cordially,

 


Kerry Thompson

[Flashcoders] Storing x and y in a bytearray

2009-03-30 Thread Jiri

I have a byte question.
I have to store a walkable area so a character 'knows' where it can walk 
or not. Currently I am using a multi-dim array based on the x and y pos 
of the tiles .


so [[1],[0],[1]..etc]

where pos(0,0) = array[0][0] = 1 (walkable)

I was wondering if I could store this using a bytearray, for storing and 
possibly faster lookup using bitwise operators. I am very knew to this, 
so I am ot sure where to begin and how to deal with it.
The range of int is sufficient to store all the data, because a full 
walkarea would take 370560 (772*480) elements in the previous mentioned 
multi array.


I could be completely wrong, but would like some advice.

I tried your solution and it works!

 var pixelPos:int = col + row * totalCols; // or x + y * 
widthOfOriginalBitmap
 buffer.position = pixelPos * 4;// each pixel takes 32 bits == 4 
bytes

 var pixelValue:uint = buffer.readUnsignedInt();

For the archives. The totalCols var is the width of the bitmap.

[Flashcoders] Strange behaviour ByteArray to BitmapData object

I came across some very weird behaviour and I can't seem to find an 
explanation for it.
I am trying to write a class that will store compressed ByteArrays that 
are retreive throught the bitmapData.getPixels.
Here is some testing code, that I wrote for the testing if a 
decompressed ByteArray can be parsed back into an Bitmapdata object.


It all works well if the uncompress/compress block is in the code. When 
i comment that code out, I get this error:


Could someone tell me what is happening here?

Re: [Flashcoders] Strange behaviour ByteArray to BitmapData object

2009-03-16 Thread Jiri
Thank you. The position=0 seems to do the trick. I actually read over it 
in the documentation. RTFM should be RTFMW(ell) !! :)


 Little tips if you want to test, instead of using setPixels to fill
 your Bitmap, using graphics.beginBitmapFill seems quicker and less CPU
 intensive (test it, I'm not 100% sure).

I dont actually want to render the bitmap. I make a black and white 
images of a hand drawn sprite, that acts as a walkarea. Every room has a 
different area and so i cache the ByteArray for every room. This 
'bumpmap' is used to check, with getPixel() if a clicked position is on 
the walkmap.
If I would render it to a graphics I will loose the getPixel() method 
for checking. Also when i use the Loader.loadBytes.


Or am i wrong?

Did you try
myByteArray.position = 0
before reading it ?

You can try to use a Loader.loadBytes to instantiate a Bitmap (it uses a 
loader but it takes no time).


Do you load the picture before storing the bytes?
If it is helping, I built a loader that is storing bytes for a cache 
system and use Loader.loadBytes to instantiate the Bitmap:

http://www.soundstep.com/blog/downloads/somaloader/

To be sure your ByteArray is compressed, you can:
bytes.position = 0;
var compressed:uint = bytes.readUnsignedByte();
if (compressed == 0x43) trace(ByteArray is compressed!)

Little tips if you want to test, instead of using setPixels to fill 
your Bitmap, using graphics.beginBitmapFill seems quicker and less CPU

Here is some testing code, that I wrote for the testing if a

It all works well if the uncompress/compress block is in the code. 
When i comment that code out, I get this error:

[Flashcoders] RegExp headache

2009-03-05 Thread Jiri

I would like some help on a regExp

I have a string and want to split it into the first character being a 
||=|=|== the second part being an int.


so 100

would return
result[1] = ''
result[2] = 100

so 100

would return
result[1] = 'undefined'
result[2] = 100

Here is what I have so far, but it is killing me.

var pattern:RegExp = /^(\d)?(^\d+)|(?)/
var result:Object = pattern.exec(tConditionalString);

I tried another approach but i am still figuring out how to do it. It 
goes something like this

var pattern:RegExp = /^():((?(2)then|else))

You have to move the timeline playhead for traceBitmap to work.
When you enter edit mode, you automatically end up in the first frame, 
so that's why traceBitmap works for the first frame, and not the others.


So, loop through the number of frames, set timeline.currentFrame and 
then you'll be able to select the elements in that frame and work with 
them.


This should do the trick:

var doc = fl.getDocumentDOM();
var library = doc.library;
var items = library.items.concat();

var i = items.length;
var item;
var timeline;
var len;
var fr;

while (i--) {
item = items[i];
fl.trace(itemType:  + item.itemType);
if (item.itemType == movie clip) {
 library.selectItem(item);
 library.editItem();
 timeline = item.timeline;
 len = timeline.frameCount;
 fl.trace(- frameCount:  + timeline.frameCount);
 for(var j=0; jlen; j++) {
  doc.selectNone();
  // move the playhead !!
  timeline.currentFrame = j;
  // get reference to current frame object
  fr = timeline.layers[0].frames[j];
  // set doc selection
  doc.selection = fr.elements;
  doc.traceBitmap(100, 1, 'pixels', 'normal');
 }
}
}
doc.exitEditMode();

Re: [Flashcoders] Help jsfl traceBitmap

2009-02-10 Thread Jiri

Muzak and others,

everything worked fine, but now i am struggling with movieclips and 
different frames on their timeline containing 1 png.

I followed your described logic.
1. go trhrough lib items.
2. Check if it is a movieclip.
3. For framecount of the timeline, do a loop.
4. For each frame get the elemtens
5. add this to the selection
6. apply the trace bitmap.
7. ERROR! Selcection not set

Would someone please be so kind to take a look...it is driving me nuts!

Thnx

code
function convert(tFlaPath , tExportPath){

fl.openDocument(tFlaPath);

var doc = fl.getDocumentDOM();
var library = doc.library;
var items = library.items;

i = items.length;

while (i--) {

 This one threw me off a bit :)
Tell me about it, it did my head in all day..
 When you enter edit mode, you automatically end up in the first frame,
That explains why, although looping through the frames, it was always 
only the first one to be converted before the error was thrown.


I will give your suggestion a try tomorrow and cross my fingers it works.

Re: [Flashcoders] What design pattern would this be?

2008-12-08 Thread Jiri Heitlager
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

2008-12-04 Thread Jiri Heitlager

Hello list,

i make the following query on an xml file to retrieve a list with 
certain node names:


var tXML:XML = data
findname_H1[EMAIL PROTECTED]/findname_H1
findname_H2[EMAIL PROTECTED]/findname_H2
/data

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

2008-10-28 Thread Jiri Heitlager
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()

class reference='injectedB' /

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.

2008-10-17 Thread Jiri Heitlager

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.

Convert the XML to a string.

Do the regExp replace on the string.

Reparse the XML?

e.g.

Might not be the fastest in the world, depending on the amount of XML

[Flashcoders] AMF objects storing in database

2008-08-28 Thread Jiri Heitlager
I came across a post on storing custom classes as an AMF object. It 
explains how to do the following.


If you ever need to store the state of a custom object in a ByteArray 
or SharedObject, or send a custom object through a LocalConnection, 
there are a few simple steps you can take that will allow your object's 
state to be serialised (converted to AMF) and preserved for future 
restoration.


src: http://www.si-robertson.com/go/serialise-custom-classes


I wanted to know, can I then just send the AMF object to a server and 
store it as a binary in a mysql database? And also is this adviceable?


Thank you,

It has been a year ago and I'd thought Adobe would have brrought out an

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.

OK, I relplied a bit in a hurry and didnt make myself clear. That is 
stupid of me, and I am sorry.
The situation is like so. I open a connection using OpenAsync. I have 
listeners listening to the Open event. When that is fired, I response 
with a method that creates 3 tables in one go, see code below. I keep 
getting an error, also shown below. If in the whole story I use open 
instead of openAsync, everything works perfect. I have now idea why that 
is??

Re: [Flashcoders] Question AIR Sqlite api

2008-04-18 Thread Jiri Heitlager

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 ...'

Muzak

Hi Jiri,

I believe it is due to the default lock type. The default lock type (DEFERRED)

 * SQLTransactionLockType.DEFERRED indicates that a lock is not acquired until

And since a CREATE is technically neither a data read or data write, but a 
scheme altering method, it could be the cause. Try changing the lock method be explicitly 
specifying EXCLUSIVE as a parameter to begin():

Sql_conn.begin(SQLTransactionLockType.EXCLUSIVE);

Hope that helps,

Re: [Flashcoders] Question AIR Sqlite api

2008-04-16 Thread Jiri Heitlager

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?

Jiri

[Flashcoders] Flash developers Berlin - are there any?

2008-04-15 Thread Jiri Heitlager
A bit of topic but here goes anyway. I currently moved from Amsterdam to 
Berlin and I was wondering if there are any Adobe flash groups or flash 
related gatherings in Berlin. If anybody knows about some place 
(on/offline) here in Berlin where I can meet some Flash developers I 
would be really happy to know


Thnx
