I am working on a Flash game that uses 2D polygon collision. It seems to me that I could sketch the 2D collision around my objects using the pen tool, and make it invisible by putting it on a separate guide layer.
how to access the data on that layer - preferably as a set of points - from ActionScript.
I am playing around with ActionScript 3 and trying to build a very simple prototype for a video game (top-down action/shooter) and realized that handling bullets is a little bit more challenging than I originally imagined.
In order to get a fairly decent "flight" of the bullet between the character and the target, I ended up using a highly modified version of Bresenham's Line Algorithm to determine the flight path of the bullet and then merely draw a tiny flash.geom.Rectangle object at the appropriate place on that "flight path" during the draw-frame stage of my application.
I haven't noticed any real problems, but I just can't imagine this being the best way to handle bullets in a Flash game. I imagine that once there are multiple enemy players on the screen and lots of bullets flying around (especially once I code in automatic weapons) that things could come grinding to a halt.
What am I missing here? I'm not really a game developer and so most of the things I'm doing I've just "made up" on the spot, but I can't figure out how to effectively handle bullets in Flash.
EDIT: As requested, here is "my" Bresenham code. I say "my" in quotes, because I basically ripped this from somewhere on the internet. My changes to the algorithm basically involve the lines at the bottom. The original implementation would find the path from player character to the target, except that every once in a while (and I wasted a little bit of time trying to figure this out but never got anywhere) it will generate the path from the target to the player. To "fix" this, I ended up just checking the first X/Y values from the path array and reversing the array if those values didn't match the X/Y values of my player character.
[Code]...
How do I actually remove the full path as in C:program filesappfilename.jpg so that the only left is filename.jpg? Substr or Substring can be use in this case to remove after detecting the first occurrence or / by looping from the string end position.

View 1 RepliesCurrently learning flash and what I would like to do is capture information from another flash program if thats possible?Basically im playing a persistent browser based game written in flash and on mouseover of a tile in the world map it displays some information, specifically in game co-ordinates and details of whats there.Is it possible to capture that with a flash program? Or is that beyond the bounds of flash? I know it can be done in other languages but its been years since I've done any programming.

View 8 RepliesI am a Flex developer and now I have started learning the fundamentals of iOS, Objective-C, and accessing server-side data. Most of the Flex projects I do are mainly in accessing server-side data with Flex from .Net, Python, and Java since we all know data access in Flex is possible only via 3 ways: Http, Web-service, and Remote Object. Out of these 3, Remote Object is the most reliable, fast and handy.ion is, do we have remote object concept in iOS? I mean is there any interface (like blaze DS, weborb) available on the market forserializing/deserializing Objective-C object type to C#, Java, and python or vice versa?

However when I try to access the xml data it is coming back as null. I understand this is almost certainly because when it is called the xml data hasn't completed it's load. How can I get round this?

I have have a problem loading and accessing data from a value object in my new project.. I load an xml file via a service, which contains title and locations of asset files, I need to be able to access the location of an asset file by specifying the title and retrieiving it from a value object.. I'm using the Robotlegs framework, here's an example of the xml:-
<?xml version="1.0" encoding="utf-8" ?>
<files id ="xmlroot">
<file title="css_shell" location = "css/shell.css" />

After reading data from XML source I like to be able to show one random item from data whenever, say, clicked a button. I think I can accomplish this by storing the data into an array and use it from the array. I would like to learn if possible to do it directly from xml without storing it into another array.
var myXMLLoader:URLLoader = new URLLoader();
myXMLLoader.load(new URLRequest("XML_NOTES.xml"));
myXMLLoader.addEventListener(Event.COMPLETE, processXML);

How do I access an array inside an .swf that is loaded using loadMovie?
this.createEmptyMovieClip("controlpanel", 999);
loadMovie("lessons/regulatoryrequirements.swf", controlpanel);

I have stored some basic data in a custom class, imported it into a project, and compiled it into an swf. Now, I want to import that swf into the library of a new, entirely separate flash project, and access the data from the original custom class inside that imported swf.

Code:
package {

I'm trying to load data from an external textfile, called "config_flash.txt". It works perfectly if applying the fetched data is done within the same function where the loading is done. However, I would like to use the fetched variables in other parts of the script.

Actionscript Code:
var varLoader:URLLoader = new URLLoader(new URLRequest("config_flash.txt"));varLoader.addEventListener(Event.COMPLETE,

View 1 RepliesI have a cs3(AS3) datagrid component and I'm tracking which row the user has selected by using ListEvent.ITEM_CLICK to listen for a selection and then event.rowIndex in the handler function and using this index no to select data from the array which was used with the dataProvider. The problem is this. If the user re-sorts the rows using the column headers, this resets the rowIndex (ie the first entry is always row 0) and so this no longer relates back to my array. Is there a way to directly access some or all of the data in the row the user selects?
View 3 RepliesI'm wondering if it's possible to access a shared object's data (once it's been changed) without reloading the swf. Specifically, I have two swfs: one changes the data in the so and lets the second swf "know" via a localconnection. I have a function in the second swf that fires via the local connection.[code]This function looks for the new value however it doesn't show the updated value in my textfield unless I refresh the browser. Thoughts?

ActionScript Code:

That's O.K. But I can't put a text in them... when I write
ActionScript Code:

It simply doesn't work!
Once a button is clicked in a submenu called SelectChar(a menu class extending my menu base class), it dispatches a custom event carrying an array of variables. This event is then listened for in the main Document Class called Engine, where the value of the passed variable can be used. For testing purposes im only passing 1 arguement in the array.
my Error when trying to trace the passed variable in isolation "trace(e.arg[0]);": 1119: Access of possibly undefined property arg through a reference with static type flash.events:Event.
Okay, i hope that made sense... heres the relevent code:

I began with a class for a movie clip rollover function FigureRollOver. It works marvellously. Three things happen:
1) it loads XML from a file "mod1_fig1.xml" and uses another class, XMLMember, to retool the scoping of the XML so that I can get at it
2) an onload call inside of XMLMember calls the myOnLoad function and transfers the XML into an array.
3) so long as the array is finished building, rolling over a movie clip attaches a new movie clip with the rollover text in it.But I don't want all those functions in one because I need it to be more dynamic, starting with being able to load any old xml file instead of just "mod1_fig1.xml", plus it seems lik overbuilding to have all of that in one class, so I've separated out the loading of the XML and building of the array into its own class, FigureXMLLoader. FigureRollOver is then left to just attach the rollover with text in it, extracted from the array built by the new class.
Problem is, though the array builds inside FigureXMLLoader, I can't figure out how to make it available outside the class. I know that I'm constructing things in the wrong order, and that the array needs to be somehow built inside the class function to be available, but I can't figure out how to do that. A cruddy work-around is to put a function call at the end of the building of the array, which calls yet ANOTHER function on the main timeline of my .swf to put the array I've just built into a new variable.This works, but it's messy. It seems like I should be able to have one line of script in the .swf that generates an array on the main timeline (or just a public array) which I can then access from my FigureRollOver class:
var myRollOvers:Array = new FigureXMLLoader("mod1_fig1.xml");
Here is FigureXMLLoader (see comments in the code for more details) which obviously does not return an array as it is, because of all the working around I've had to do. Note the "testing" variable, which can be traced from the main timeline of the .swf, but I will get "not what I want" because of course the array hasn't been built yet, and never will be, inside of the declaration as it is. How do I get it in there so I can return an array?
I want to extend the dictionary class. Everything works so far except that in some of my methods that need to reference the dictionary's content I make a call like:
this[ key ]
It doesn't like that. It just tells me that there's no property 'key'. Is there a way to way to access the data within this class?Also, I'm using an integer for the key.
Edit: I've found that the same behavior happens when you extend Array.
var myArray : Array = new Array();
trace( myArray[ 0 ] );
var myArrayExtender : ArrayExtender = new ArrayExtender();[code]....
Where in this case, myArray returns "undefined" and myArrayExtender throws error 1069. ArrayExtender is an empty class that extends Array and calls super() in the constructor.
