ActionScript 3.0 :: Count The Amount Of Items In The XML File And Then Create A For-each Loop
Sep 24, 2009
I have 10 dynamic text fields inside a movieclip, which are populated via an XML file. However, the xml file sometimes has less than 10 items. It never has more than 10. This results in the following error, which is normal. I need the code to count the amount of items in the XML file and then create a for-each loop. I can visualize it, but I don't know how to write it. Basically what I need the code below transformed in to is this... (notice the #'s)

Well, i have this line of code
Code:
var t1:thumbBack = addChild(new thumbBack(x, y));
And i want to create many thumbBacks with names t1, t2, t3... with a for loop.
I tried something like this, but it doesnt seem to work
Code:
for(i=0; i<8; i++){
var this["t"+i]:thumbBack = addChild(new thumbBack(10 + i*200 , y));
}

This is a hard question to phrase and having trouble finding the right search terms. In the last couple of weeks I have been learning AS 3.0 and the fantastic Classes that are cool as heck (not a programmer... well sort of). Everything has been working great and I've grasped the concepts well, but because of my lack of experience I am not sure of the "best" way to do some things. For example where (which "as file" to create an array of characters?)
This is a very simple game:
25 "characters" (character class in Character.as)
All characters have the exact same properties with different values:
charName:int
life:int
strength:int
movement:int
type:String
char_mc:MovieClip (or sprite.. probably mc)
There are 2 types of characters; shipCrew and aliens. The differences between the two is that shipCrew can use various weapons and have unique "names". Aliens don't have names, just a type and they can grow and/or multiply. All of the interaction and basic game play I can handle no problem once I figure out "where" to create my characters and classes and or subclasses. My initial "training experiments" worked well... until I started reading up on "best practices" in coding and realized I had it kind of all mixed up and backwards. My concern is "doing it wrong at the start".
My first stab at this was to create the array of ALL characters in the "main.as" class for the document, then looping the array, creating new character instances on the stage. Since each character has different properties I just created the same array properties for each with a different value. So basically I am "hard coding" all the characters up front "by hand" so to speak with all the properties in the array. Since they were all identical basically, looping the array to "do stuff" was straight forward... for now. The array looks horrible in the code and is hard to "read" but since it's all "static" anyway it doesn't seem to matter... but would still like to "do it right".
Game play is simple because at a basic level each character regardless of what type it is will do the same thing. I would expand on the differences later. However as part of this inquiry I will need class instances on the stage to communicate with each other (like the idea of a registry for this). So my questions are:
Should I create individual as class files for all 25 characters? (icky?)
Or use an array to store the character class objects? A dictionary? A vector?
They all worked, I tried them all. I like arrays better because easier to deal with, but dictionaries look like fun and might be more efficient (only 25 items, how bad could it be?) storing in an object works too. Whatever type of "array thingy" I choose, Which class file do I create the array in? In the "main" document class or the character class itself? In another type of file like an "init" file? Could I create a "custom" file "type" or class... thingy like "CharacterCreator.as"? How about using a registry?

I have a list of 10+ items. when i click back up the list 1 step i call the code below to remove a thumbnail image associated with that list item.
if(indice < count-i){mx.core.Application.application.removethumb.dispat chEvent(new MouseEvent(MouseEvent.CLICK));
}
HOWEVER: I would like that if - for example i am on item 10 and click to item 4 - all the thumbnails between 4-10 are removed. it it possible to dispatch this click event X number of times dependant on the - count value?? FOR REFERENCE: THIS IS THE CODE THAT REMOVES ALL ITEMS BEYOND THE ONE I HAVE SELECTED:

I have been having a serious issue with custom video where flash is saying that the amount of the video so far played is MORE than the amount that it has downloaded, which is clearly impossible. This results in various problems, such as the playhead (scrubber) moving past the end of the loader bar. I posted a simple demo that displays the amount loaded and the amount played in text fields.

So I have been having a serious issue with custom video where flash is saying that the amount of the video so far played is MORE than the amount that it has downloaded, which is clearly impossible. This results in various problems, such as the playhead (scrubber) moving past the end of the loader bar.I posted a simple demo that displays the amount loaded and the amount played in text fields. You can see it at: URL...[code]I encoded the video at a high rate so that it would download slowly. It may not playback smoothly, which I am not concerned about. What I am concerned about is the numbers below the video what are derived from ns.bytesLoaded and ns.time. If you watch it for a bit, the amount played should exceed the amount loaded.
I double checked the video duration and the bytestotal that flash is reporting and they are correct. I don't know of any way to check the accuracy of bytesloaded.If your internet connection is super fast, you may not see the issue - it only occurs when it is playing back faster than it is downloading - if this is the case, you may need to throttle your speed down, or start downloading a large file while you are watching this demo in order to see the issue.But this is a serious issue and means that building custom video interfaces with loadbars and playheads is impossible!

I was wondering if you could loop through your library or a specific folder in your library and get alle linkage names of items that have 'Export for Actionscript' checked. I have an amount of items in my library of which I want to random pick one. Of course I could just use an array of linkage names that correspond to my library items, but I was wondering if there is a more efficient way.

What I've got is a menu that loads images as buttons. It will only display menu items that are within a certain group (i.e. if themenuitem.node Value == groupid[q] then it will display that menu item. Each of the menu items has a unique number (Itemnumber[n]). I have a loop that goes through and displays the menu items that are within a certain group. I am currently able to also find out the unique number of each of the menu items where themenuitem.nodeValue == groupid[q], but what I want to do with these numbers, is place them all into an array as it loops through.So, say for example, it finds an item in the loop. It tells me this item is number 4 (if I tell it to trace(Itemnumber[n]) within the loop). Then, it finds another item in the loop, and it tells me this item number is 6. I want to be able to add items to an array as it loops through, so I'll have an array at the end like this: (4, 6).Currently my ActionScript looks like the following. Never mind if there are variables that are not defined in there -- they have been defined in other parts of my movie.[code]As you can see, I've made an attept at achieving this by trying numarray[numarraylength] = n; -- but all this does is send me an array, then overwrite it next time it loops (so I get an array like (4, 4), then one like (6, 6). I've added comments in the code to further explain what I'm trying to do.

If you have a series of sprites created in a loop:
ActionScript Code:
for (var i:int = 0; i < numItems.length(); i++) {
var mySprite:Sprite = new Sprite();
}
Which you added event listeners to, in the same loop:
ActionScript Code:
for (var i:int = 0; i < numItems.length(); i++) {
var mySprite:Sprite = new Sprite();
mySprite.addEventListener(....
}
How can you remove those listeners, then add them again? I need to kill and re-enable the listeners of many sprites which were created that way.

I am attempting to use a loop to create text field with the loop's current value. The code looks like this:
ActionScript Code:
for (var i = 1; i<=10; i++) {
var 'nameHolder'+[i]+'_txt':TLFTextField = new TLFTextField();
'nameHolder'+[i]+'_txt'.x = 40
'nameHolder'+[i]+'_txt'.y = 40
'nameHolder'+[i]+'_txt'.text = "Hello World"
}
So essentially what it should do is create 10 text fields at 40, 40 with the text: "Hello World".
