Actionscript 3 :: Arrays - Array Setters Does Not Do Anything
Nov 1, 2011
I need to change a text field every time values in an array is updated, and I tried putting the code in the setter. However, the code is not being called. Even if I do this
public function set resources(value:*) {
//this function does not seem to matter at all
}
Nothing happens. I think AS3 overrides setters for arrays, how do I get the functionality other than inserting a changeTextFields(); every time I change the array?
I am running into some trouble adding an array into another array to create a multi-dimensional array.The code appears as below:
var slideDataArray:Array = new Array(); var slideShowDataArray:Array = new Array(); slideDataArray[0] = xmlData.SlideShowParameters.SlideShowImagesDirectory;[code]........
I am looking for a means of placing the slideDataArray into a 'slot' or value of slideShowDataArray so that I can in the end pass the slideShowDataArray as a parameter to another function.As of now, the last slideDataArray appears 11 times (the loop runs 11 times) in slideShowDataArray and the way the code is written the slideDataArray is unique every iteration of the loop.
what's a simple way to combine arrays with as3? by combine, i mean that contents of one array are pushed into another array.I already tried a for loop and push.
i have two arrays of DesplayObjects and i want to add all the objects in the second array to the end of the first array, i knew that i just can just do a loop and puch em into the array, but i wondered if there was a simple function for doing this?
Long story short: I want to search a multidimensional array in AS3 for (in this example) the location of 6 strings - all of which are stored in another unrelared array. Long story long: Once I get the locations (in the multidimensional array) of each string, i then know where it's located, and can access other atributes of that object - so if i found the string "box3" is located in element [5] of my multidimensional array, i can now target: multiArray[5][3] to return the 4th item stored (keeping in mind we're starting from 0, so 3 is the 4th position).
I can get this to work once, but I'm trying to set up a for loop based on the length of my basic string storage array - this array holds (in this example) 6 instance name strings - each time my for loop loops, i need to run a search in my multdimensional array for the next consecutive instance name. Then, once I've located all of them (and store the results in a new temporary array) I can dig around in each location for the info I need.
I have quite alots of display objects to manage during runtime, so Im currently using Arrays to manage them. But the problem is I have few many types of displays objects(eg. Tile, Npc and Building) which are basically MovieClips linked to the library. Each display object plays different role where it will be checked on enter frame, a loop.Method 2 sounds much more faster and extensible however Im worried if it would affect the checking rate of each display object during runtime as the displays:Array grow larger and probably making it glitchy.So which one of the following method is faster+less glitchy and explain why you choose it.[code]
I've been seaching on how to get the key names of a flex Array as there is no such function in the Array class. Here is my answer that may be usueful to any of you.
I know that an ArrayCollection is a wrapper over an Array, but what I wanted to know is when to choose one over the other? Will the over usage of ArrayCollections result in performance?
I am attempting to build an array of arrays that will with the following syntax. My output is definitely not what I am trying to achieve. Here is my code:
[Code]...
My output is coming out as 6 references to "Set3". There is obviously something wrong with my for loops, but I can't figure it out.
I have a chart and am trying to display the "volume" in a line chart as the primary series & the "temp" as a column chart as the secondary series...(the "compound" will be shown in the datatip):
[{date=Tue Feb 08 19:00:00 EST 2011, volume=1200, 1={temp=-50, compound=helium}, 0={temp=-45, compound=oxygen}}]
I can get the "volume" series to display fine, but cannot get the "temp" series to display...how do I access them? Right now I have:
I have an array of movie clips (representing band members) which have various properties, among them them a property which tells where the band member went to after they left their current band. For those who formed a new group, I want to create an array. Within that array, I want to group all the ones that left for the same group into secondary arrays. So, if you had five band members and 2 of them left for group X and 3 left for group Y. What's the best way to do this? This is, roughly, my code:
[Code]...
Alternatively I suppose if I could do without a multidimensional array and just loop through all the members and say - for those members whose group is the same, perform this function, with the name of that same group passed as the parameter for the function. I guess the trouble I'm having is identifying who's the same.
I have the following problem. I wanna load 3 pictures to the stage using LoaderMax. Their path is stored in an array (urls), and finally I wanna have all their displayList objects in a new array called pictures.here's my code:
var urls:Array = new Array("../data/bild1.jpg","../data/bild2.jpg", "../data/bild3.jpg"); for(var i:Number = 0; i< urls.length; i++){ var loadery = new ImageLoader(urls[i]);
I have a for loop with counter set to the number of items in the arrays, with the idea of inserting data from each array into the fields of the following DiffArray. I am getting Error #1009: Cannot access a property or method of a null object reference and I cant see why.
I can find plenty of ways to remove duplicates with literal datatypes, and I guess at an absolute pinch I could use toString and adopt one of those, but there surely must be a better way of doing this?
For example, when users are connecting to this application they are given a userid var, then it's inserted into the array. So, i'm using chosenUser = usersOnlineArray[Math.round((Math.random()*usersOnlineArray.length))]; to pick another random user. But i need to make sure it doesn't pick the userID they personally were assigned so they don't end up getting themselves. how would i use that code but tell it to "remember, make sure you dont pick userid" maybe I could do something like
I have movie clip in an array (newStep) that is being added to the stage dynamically. It's randomly choosing a frame to go to every time an instance is added. There is a nested movie clip (stepLine) that i need to change the alpha of. This code actually works for adding a string to to the dynamic text box (pointsDText) but when i try to access the nested movie clip (stepLine) it gives me 1009 null object reference error. The funny thing is the code actually works and does change the alpha of the movie clip but i still get that error, and i think it's making my game more glitchy. I've tried using if(contains(steps[r].stepLine)) too but it doesn't work. Is there a better way to access this movie clip without getting the error?
Sorry if this is a little n00b-ish. I'm working in AS3. I've got an array of 8 buttons. I'm currently hiding the button that is clicked using e.currentTarget. How can I tell flash to make all the buttons that aren't the currentTarget to become visible (i.e. if a button has been hidden by previously being clicked, how do I tell it to become visible again when another button is clicked?)
Lets say I have an array which has n dimensions. Now in order to access a slot you typically use: array [1][0]What if the number of dimensions are not known at compile-time, is there an easy access like:
slot = "1,0" array [slot] // accessing 1,0 Which means I can also easily navigate back and forth
I have some script which grabs stuff from an xml file. The stuff grabbed from the xml is in a loop to create an automatic menu. This is all fine and dandy. Say there are 9 items in the xml file, I get 9 menu items with their unique id's.What I want to do is define an array for comparison against the info taken from the xml file. Say in the xml file I have nodes set up for Apple, Pear, Banana and Orange. With my current script I would get a menu with these items on it. What I need to do is be able to specify the items I want to appear on the menu. For this example I would want Apple and Banana only.
I have experimented with if statements, and it takes too much code to accomplish what I want I am sure there is a more compact way. My idea is to set an array with the items I want in it,then when the information is taken from the xml file,I need the script to do the function of creating menu items only with the items I have specified in the array. Below I have added the code, which has been modified from Kirupa's own squirrel finder tutorial.I need the code to be as reusable as possible, ie only the array would need to change.In my code the variable featureType would contain the information I need to compare against.
Code: //set limits on the features that need to display // define array var featureLimits:Array = ["Apple", "Banana"];[code].....
