[Flashcoders] Detecting if fullscreen is or is not allowed
Hi. :) I am building an AS3 video player and would like to remove the full screen button from the stage if the allowFullScreen parameter in the HTML embed code for the movie was not set to true. But I've not been able to find out how to check if the Flash is allowed to go full screen or not. Surely there's a parameter set somewhere in the Flash with that info? I've been searching through the LangRef and have googled about it, but I've not been able to find where this parameter is hidden. It's probably so simple that I'll feel very stupid for not figuring it out... -.- -- Andrew Murphy Interactive Media Developer amur...@delvinia.com Delvinia 370 King Street West, 5th Floor, Box 4 Toronto Canada M5V 1J9 P (416) 364-1455 ext. 232 F (416) 364-9830 W www.delvinia.com ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] Normalising Numbers
Hello FlashCoder...
maybe it's because it's late but it's getting a little confusing, and google is
not being friendly right now.
seems to works fine with positive numbers, however - i am trying to normalise a
range of positive and negative numbers... ( code simplified not to find min and
max values ).
I am currently am coming up a little short... hope this code does not give
anyone a headache; if you fancy a stab, or if you can point me in the right
direction
... otherwise ... will post results when i get there...
Code:
public function test() {
trace('')
trace( testNormalizeNumbers( [ 1 , 1.5 , 2 ] , 2 , 1 ).toString() );
trace('')
trace( testNormalizeNumbers( [ 1 , 1.5 , 5 , 1 , 6.4 , 6, 3, -2.6, -1
, 3.5 ] , 6.4 , -2.6 ).toString() );
trace('')
trace( testNormalizeNumbers( [ -1 , -1.5 , -5 , -1 , -6.4 , -6, -3,
-2.6, -1 , -3.5 ] ,-1 , -6.4 ).toString() );
}
public function testNormalizeNumbers( a : Array , max : Number , min : Number )
: Array {
var result : Array = new Array();
var nMax: Number= ( min 0 ) ? max - min : max +
Math.abs( min );
for ( var c : int = 0 ; c a.length ; c++ ){
var pRangedValue: Number = ( min 0 ) ? a[c] -
min : a[c] + Math.abs( min );
var normalizedValue : Number = pRangedValue / nMax;
result.push( normalizedValue );
}
return result;
}
Thanks

Re: [Flashcoders] Normalising Numbers
I think you're complicating the problem by introducing Math.abs which, I was
once told by a mathematically inclined colleague, is an arithmetic atrocity
(I've taken note of that since then and the nice thing is that almost
always, signs just work they way out without any extra help).
The formula is simpler than you probably think. You just need to find the
size of the range, that is the difference between the max and the min
values. Forget about signs, just take the max value and substract the min.
Easy as that.
If you have, say 10 and -4, the range size will be 14:
10 - (-4)
--
10 + 4 = 14
The signs don't matter, as long as you always substract the smaller value
from the bigger one.
Now, once you have this value, you just have to find how far the ranged
value is from min and then scale it.
Let's say your value is 3. I picked 3 because it's easy to see it's in the
middle and that the result should be 0.5.
So:
rangeSize is 14 (max - min).
min is -4
rangedValue is 3:
How far is rangedValue from min?
rangedValue - min
That is:
3 - (-4)
or
3 + 4 = 7
Now, the last step, scaling it:
(rangedValue - min) / rangeSize
Replacing the values:
(3 - (-4) ) / 14
(3 + 4) / 14
7 / 14 = 0.5
And there you have it.
So a function to normalize a ranged value could look like this:
function rangedToNormal(ranged:Number,min:Number,max:Number):Number {
var rangeSize:Number = max - min;
return (ranged - min) / rangeSize;
}
Going the other way is simple too:
function normalToRanged(normal:Number,min:Number,max:Number):Number {
var rangeSize:Number = max - min;
return min + normal * rangeSize;
}
(Though above you might want to validate that the normal value is actually
normalized before converting it to the passed range)
Also, I'm not sure how you are calculating the min and max values of your
list, but if there aren't other specific requirements, you could just use
Math.max and Math.min. They accept a variable number of arguments, not just
two, so Function::apply comes handy here:
var min:Number = Math.min.apply(null,list);
This will give you the min value of the list with just one line, no loops,
etc.
So, to wrap it up, you could write your function in just a few lines, like
this:
function normalizeNumbers(list:Array):Array {
var min:Number = Math.min.apply(null,list);
var max:Number = Math.max.apply(null,list);
var len:int = list.length;
var result:Array = [];
for(var i:int = 0; i len; i++) {
result[i] = rangedToNormal(list[i],min,max);
}
return result;
}

[Flashcoders] Re: AIR for Android - what's the go?
Thanks Ed. Is that to say that AIR for Android is included in CS5 Pro? I'd like to find out how I can start getting into this myself. On Fri, Nov 26, 2010 at 3:37 PM, Ed Murphy contact.edmur...@gmail.comwrote: Yep AIR for android is very much alive and kicking... I recently released a simple quiz game called JeresySure? You can find it on the marketplace. Anywho, CS5 pro allows devs to not only build but deploy the app locally as to debug over wifi. Tracing and what not. It even includes a simple way to create certs, when it's time to launch. Keep in mind though, many native android capabilities are still not available through the AIR player. The progressDialogue box comes to mind.

So excite! Unfortunately, I get the impression that the AIR for Android Extension for Flash CS5 was only available under a prerelease program, which I think has now closed (?) So, would anyone know what the status of AIR for Android is? Would latecomers like me still be able to dive in, or how long would it be till that happy day? Is it still going to be a CS5 extension when it's released For Realz? Also, I apologise in advance for unintentional but probable gormlessness of these questions. Thank you!
