[Flashcoders] Detecting if authoring mode (Flash 8 AS2)

2009-04-02 Thread Paul Steven
Is there a property or function to detect if a Flash movie is being tested
in authoring mode or live on the web?

Basically I have added a random variable to my xml file when loading it to
prevent caching.

The following works in both authoring and when live

myXML.load(xml/homeFlashContent.xml);

Whereas the following including the cache busting code doesn't work when
tested within Flash IDE.

my_Date = new Date();

myXML.load(xml/homeFlashContent.xml?+my_Date.getUTCSeconds());

I would therefore like to have an if statement something like

If (boolAuthoringMode == true) {

myXML.load(xml/homeFlashContent.xml);

} else {

myXML.load(xml/homeFlashContent.xml?+my_Date.getUTCSeconds());

}


If there are any better solutions please let me know.

Thanks

Paul

Re: [Flashcoders] FPS question

2009-04-02 Thread Ian Thomas
Also = try to redraw as little of the screen as possible from frame to frame.

If your entire screen is constantly redrawing, that takes a lot of
processing power.

So alpha fades that affect the entire screen or moving/animating a
sprite which covers the entire screen are problems.

The Flash Debug Player has a right-click context menu option called
something like Show Redraw Areas (I forget).

HTH,
  Ian


P.S. There's a bug in FP9+ - possibly still in 10, I can't remember.
Calling setChildIndex() forces the entire display to be redrawn.

Hi Paul,

   Take a look at System.capabilities.playerType.


   System.capabilities.playerType==External means you're running in the IDE.

   System.capabilities.playerType==Plugin means you're running in a browser.

[Flashcoders] Proof of Concept - HTTPService object doesn't require crossdomain-policy file

2009-04-02 Thread Johan Nyberg
Hi, thanks for all the response to my question about the 
crossdomain.xml. But... I didn't get a lot of response to the fact that 
HTTPService can access public feeds/content on other sites without the 
need of a crossdomain.xml


Please check out the code included at the end of this post. I've created 
a small AIR application (with a certificate) and it works without a 
problem.


Am I missing something?

But again.. if my Flash app isn't allowed to access content on another 
site, I can always throw together a simple php-script that extracts the 
content for me that my Flash then can read...


And then I can go ahead and create my evil banner ad. ;-)

I understand that crossdomain policy files are here to stay. I just 
don't understand why they don't allow me to access content on other 
domains that I can access in other ways and then pass on to Flash.

Johan - from memory, I'm not sure AIR needs the crossdomain file,
whereas browser-based Flash does.

That might explain the discrepancy.

(That is from memory, though - probably needs doublechecking...)

2009-04-02 Thread Paul Andrews
Looking at the flash player security model, a projector has a local security 
sandbox while a browser launched swf has a security sandbox that includes 
it's own domain, so this would explain why your projector would be 
restricted.

Re: [Flashcoders] Proof of Concept - HTTPService objectdoesn't require crossdomain-policy file

2009-04-02 Thread Glen Pike

Hi,

   It's an AS2 Flash application running standalone on Linux requesting 
stuff from the localhost on various ports - the irritating thing is I 
still have to implement x-domain files / responses on every port I 
connect to, I tried setting a policy server up on the default port as 
per the instructions on the devnet site, but this did not work..


   My point is that the standalone Flash application is an exe, like 
Air, so implies that a higher level of trust is required to run it, 
therefore it should be allowed more liberty than a browser based Flash 
app.  This is one of the most irritating things about doing standalone 
stuff - I can't load files from the file system because I am requesting 
over the network.  I am doing standalone because this is legacy stuff 
for a kiosk...

Seems to me that if you say network only to an executable, it's 
like running it in a browser with no default domain, whereas an AIR

In the browser the flash swf is loaded from a particular domain and

In an Air application there is no concept of the domain that the

[Flashcoders] Bitwise selection

2009-04-02 Thread Jiri

I am new to bitwise operators, so I am trying to learn it.

I have the following code and it works half. I am using a switch case to 
get the result, but this is messing things up. I could revert to and if 
- else statement, but I was wondering if there is a more elagant way of 
doing it. I post my code below, and would have some advice.


var NO_RESTRICTION:int = 1;
var NUM_ONLY:int = 2;
var CHAR_ONLY:int = 4;

var RESTRICTION:int =  NUM_ONLY ;

function setInputCharRestriction(tInt:int):void {
RESTRICTION = tInt | tInt2 | tInt3;
}

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

trace('all ' , Boolean(RESTRICTION1))
trace('num ' , Boolean(RESTRICTION2))
trace('char ' ,Boolean(RESTRICTION4))

switch(RESTRICTION){
case RESTRICTION1 :
tRestrict +=\u0020-\u007E;
trace('all')
case RESTRICTION2:
tRestrict = 0-9;
trace('num')
case RESTRICTION4:
tRestrict = A-Z a-z;
trace('char')
}
trace('restrict field ' , tRestrict)
return tRestrict;
}

getRestrict()

 Is there a property or function to detect if a Flash movie is being tested

 Basically I have added a random variable to my xml file when loading it to
 prevent caching.

 The following works in both authoring and when live

 myXML.load(xml/homeFlashContent.xml);

 Whereas the following including the cache busting code doesn't work when
 tested within Flash IDE.

 my_Date = new Date();

 myXML.load(xml/homeFlashContent.xml?+my_Date.getUTCSeconds());

 I would therefore like to have an if statement something like

 If (boolAuthoringMode == true) {

        myXML.load(xml/homeFlashContent.xml);

 } else {

        myXML.load(xml/homeFlashContent.xml?+my_Date.getUTCSeconds());

 }


 If there are any better solutions please let me know.

Re: [Flashcoders] Proof of Concept - HTTPServiceobjectdoesn't requirecrossdomain-policy file

I think that my point was that the sandbox permissions for the projector are 
restricted to the machine it runs on and you need the policy file in place 
to go anywhere else.


I'm not saying Adobe did the right thing for projectors, just how it is.

Hi,

   It's an AS2 Flash application running standalone on Linux requesting 
stuff from the localhost on various ports - the irritating thing is I 
still have to implement x-domain files / responses on every port I connect 
to, I tried setting a policy server up on the default port as per the 
instructions on the devnet site, but this did not work..


   My point is that the standalone Flash application is an exe, like Air, 
so implies that a higher level of trust is required to run it, therefore 
it should be allowed more liberty than a browser based Flash app.  This 
is one of the most irritating things about doing standalone stuff - I 
can't load files from the file system because I am requesting over the 
network.  I am doing standalone because this is legacy stuff for a 
kiosk...

Re: [Flashcoders] Bitwise selection

2009-04-02 Thread Mark Winterhalder
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,

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

[Flashcoders] as3 rollover rolloff issue..

2009-04-02 Thread Preston Parris
So basically I have a bunch of thumbnail images set up in a grid form, each
is the same movieclip just multiple instances of it. This movie clip has a
rollover and rolloff state that basically scales the image up, this is done
with external as that loops through and creates the event listeners for each
one. If i roll over a movie clip and then roll off at normal speed,
everything works as intended, the old one scales down to normal size, and
then new one scales up. The issue comes when you quickly roll off and then
back on. The movieclip gets stuck in scaling down to about half way. Any
ideas on how to fix this? Also I dont want to remove all of the event
listeners for the other clips until it scales back down because it would
take away from the visual effect.

thank you!

Re: [Flashcoders] as3 rollover rolloff issue..

2009-04-02 Thread jonathan howe
Preston,

There are two possible issues:

1. The scaled image is overlapping other scaled images and messing up your
chain of events fired
2. The tween method you are using to scale is not being properly terminated
and restarted/triggered. (How are you scaling the images?)

I would start by putting a trace action on both my event handlers for each
image (maybe tracing image name/id # for clarity) and seeing what the output
is: if everything happens in the expected order then I would look towards
blaming #2.

[Flashcoders] Flashplayer positioning

2009-04-02 Thread Glen Pike

Hi,

   I have just setup FP10 in standalone on my Gentoo Linux box and am 
running a SWF from the command line in standalone mode.


   The x, y position of my SWF is all wrong - the SWF is positioned 
mostly off the screen.  Reverting to FP9 standalone it works fine.


   The SWF is compiled for AS2.

   Does anyone have any ideas about this??

RE: [Flashcoders] Bitwise selection

2009-04-02 Thread Kerry Thompson
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

Re: [Flashcoders] Proof of Concept - HTTPService objectdoesn't requirecrossdomain-policy file

2009-04-02 Thread Muzak
I haven't really looked into the differences between standalone and AIR - haven't created a projector in years - but my guess is 
that because you have to install an AIR application (and are therefor informed/warned about the risks that entails) it is allowed to 
do more than a standalone executable (projector).


So basically there are 3 different player security models:
- Standalone
- AIR
- Browser plugin

Here's an article explaining the AIR security model:
http://www.adobe.com/devnet/air/articles/introduction_to_air_security.html

@Johan:

Please check out the code included at the end of this post. I've created a small AIR application (with a certificate) and it works 
without a problem.



Am I missing something?


Yes, as I explained earlier, this has nothing to do with HTTPService.
This is about different sandboxes: standalone, AIR and the browser.

Muzak

Hi,

   It's an AS2 Flash application running standalone on Linux requesting stuff from the localhost on various ports - the irritating 
thing is I still have to implement x-domain files / responses on every port I connect to, I tried setting a policy server up on 
the default port as per the instructions on the devnet site, but this did not work..


   My point is that the standalone Flash application is an exe, like Air, so implies that a higher level of trust is required to 
run it, therefore it should be allowed more liberty than a browser based Flash app.  This is one of the most irritating things 
about doing standalone stuff - I can't load files from the file system because I am requesting over the network.  I am doing 
standalone because this is legacy stuff for a kiosk...

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.

not sure, maybe FP10 defaults to a different stage alignment. Maybe
try explicity stating the stage alignment and see if that fixes it.
