Re: [Flashcoders] accessing embedded cue point names
cuePoint event object has info property, which is an object contains properties such as name, time, and type. In your situation you would just fire some actions depending on the name of the cue point.

I can fire events via myVid.addEventListner(MetadataEvent.CUE_POINT, doSomething); which works fine, but I want to listen directly for the individual cue points by name. Is there a CUE_POINT.NAME property or something similar that will allow me to fire events based on the cue point name:string? Any advice is greatly appreciated. Sam PS. should I embed the cue point as Navigation cue point as opposed to Event cue points? ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
[Flashcoders] Determining probablity of a random pick.
Hello list, I have an XMLList that can vary in length. I pick a random node each time using the simple method below: code var tRandom:int = int(Math.random()*tXMLSource.nodes.length() ); return tXMLSource.nodes[tRandom] /code Now i would like to change it, so that I can specify a weight to each node. This weight would have to determine the probability the nodes get selected out when a random pick is being performed. Does anybody know how to build such an algorithm? Much appreciated, Jiri ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders

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.

Re: [Flashcoders] Determining probablity of a random pick.
Thank you i understand it. Could u please elloborate on the last part ..You can optimise this by using an array of pointers.. Do you mean that this; a weight=5 b weight=1 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' big amount of memory?

Re: [Flashcoders] Determining probablity of a random pick.
An easy way is to if say you have 3 objects in a list given a weight options[0].weight = 1; options[1].weight = 3; options[2].weight = 4; instead of having it have three selections, you could add the weights and make it have 8 to choose from that point to the option. choice[0]=0; choice[1]=1; choice[2]=1; choice[3]=1; choice[4]=2; choice[5]=2; choice[6]=2; choice[7]=2; Jiri wrote: Hello list, I have an XMLList that can vary in length.

RE: [Flashcoders] ReferenceError: Error #1065 issue
Thanks Mario!
I actually found the solution to this. It was my own mistake, of course.
I've got a base level swf loading in a child swf which contains the super
class and subclass mentioned below. Turns out the loading swf also uses the
super class, and I hadn't recompiled it in the process. It was loading the
older version of the super class into memory first, so the updated
definition compiled into the child swf was not being used.
Thanks again for your response,
Bob

If you override that function like so, does it compile (to make sure the
override is correct) and do you see the trace (to make sure the call is
correct)?
override protected function mthGetPDataTag(stgInput:String) :String
{
trace('call worked')
return '';
}

Hi list,
This should be simple, but for some reason refuses to cooperate. I'm
working
in AS3, CS3.
I've got a super class (HsSegment) and a subclass (HsSegment_qtd1), both
are
public. In the super class are the definitions for many methods, including
this definition:
protected function mthGetPDataTag(stgInput:String):String
{
//...Do stuff and return a String...
}
In the subclass I've got the call to this method:
var stgEg:String = mthGetPDataTag(stgInput);
When testing in the IDE this works fine. When testing in the browser I
get
a runtime error,
ReferenceError: Error #1065: Variable
hs.segments.classes:HsSegment_qtd1::mthGetPDataTag is not defined.
I've googled and found plenty of questions around this, but no answers,
other than 'make your classes public', which they are.
The other methods in the super class are defined and called essentially
this
same way and work fine in both IDE and browser. What makes this one
special?
What am I missing? Any help is appreciated.
Thanks,
Bob

[Flashcoders] using Bitmap for hitArea
If I draw a circle using the Graphics and Shape classes, and then add the shape to a sprite, I can use the sprite for the hitArea of another sprite and it works just fine. Everything within the circle is a hit, everything outside of it is a miss. However, if I create a sprite containing a Bitmap drawn from this same circle and try to use this sprite for the hitArea, the entire rectangle becomes the hit area. I've played around with different alpha-levels, using white and black, and using the opaqueBackground setting. Nothing seems to work. Am i missing something or is this a known limitation? I'm using AS3 under Flash CS3. Thanks! ___ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
