how do you find an object's index / position within an array in flash actionscript 3? I am trying to set a conditional up in a loop where, if an object's id is equal to the current_item variable, I can return its position within the array.
I'm writing a multi-layered drawing app, and I want to be able to move the layers up and down. It's easy enough to change the objects in the display list and move the buttons, but in order for it to work continuously I need to be able to change the index of the button objects in the array so they are targeted properly by the function. Is there a way to do this in AS3?
After chatting with my coworkers, they have suggested I enumerate this into a large array of indexed values with references to which index they are associated with, for instance [code]...
I was just wondering whether it would be possible to remove an object from an array without referencing its index, for example when the index is unknown, or when you want to splice it from within the class itself, like ina die function for an enemy in an array. I have a project due on Friday morning, GMT.
Assume I have an array with references to different display objects on the stage. The display objects do not have any other explicit references except for the array indexes. How do I evaluate if a certain index of the array is a reference to a certain display object?Some code to clarify:
How to make a kind of array that index things based on a object? but not being strict like dictionary.
What I mean: var a:Object = {a:3}; var b:Object = {a:3}; var dict:Dictionary = new Dictionary(); dict[a] = 'value for a'; // now I want to get the value for the last assignment var value = dict[b]; // value doesn't exits :s
How to make something like that. To not be to heavy as a lot of data will be flowing there. I have an idea to use the toString() method but I would have to make custom classes.. I would like something fast..
I have used a method to shuffle a part of a Array, but i noticed that it does not work very well.When i run this method I sometimes get empty array values.So if you would try the example below and test it out some times you would get a right result but sometimes a wrong result.For example when i run this i get in my trace output:
a,b,c,d,g,,e,f (here after the g it goes wrong) a,b,c,f,g,d,e (here it goes right) a,b,c,d,,g,f,e (here it goes wrong)[code]...
I thought that there was a way to be able to name array indexes. Like instead of myArray[0], it could be myArray["tileFour"]. I thought that instead of using index numbers one could use index words.
I have a game map made of tiles, each tile is stored in an array called _tiles.The very each tile has a "plantable" parameter, which determines whether or not something can be placed on it.Then i loop through the array and check the position of each its elements against the mosue cursor, so I know which tile am I hovering with my mouse.
And it works pretty good. The problem is that even though I know what is the position of the tile I'm having the cursor on, I still lack the knowledge of what index is that tile. I simply can't tell where exactly in the array is placed this tile. I just know its position. The reason why I want to know the index of it, is because it's the only way for me to set a proper flag, namely whether it's plantable or not. Here's the code:
Is there a way I could specify the index of a array using this short code:[code]How would I go about giving a custom index name instead of it being myArray[0]? I could do it the long way like posted below, but I was wondering the there was a way to shorten this:[code]

Consider an array with x number of elements (of type Object) where some of the elements might be undefined.I use a for-each loop to access all the elements of the array that is not undefined (since it simply skips the undefined elements).But I also want the index of that particular element.The only option I can see is to use indexOf(). But it feels a bit like looking for water on the other side of the river so to speak.
When looping through long arrays each frame, is there a change indexOf() might slow it down? or does the for-each loop somehow know what index it's dealing with?
I am working with a set of external XML data, and putting it into arrays. I have set up images and text on a page using XML data, which, when clicked on, will populate a popup window with XML data from the same index. For some reason, when I trace the index of the array, it comes up as -1.
I have a tricky problem in that I have an array that has been populated with strings ("item1", "item2", etc). However, at a certain point I need to pull one randomly out of the group, via a random number function. The issue is I cannot reference the items in the array by a number, I get an error. So when I try to get myArray(5) it doesn't work.
How can I work around this so I can grab a random item in my string array?
I am creating a row which have 8 thumbnails in it, I save these in a array, When user drag row right to left then first Movieclip shift to last position, then i splice array 0 index and push to last position.. it works fine but when i drag it left to right then I need to cut last index of array and i need to push on first position, but it is overwrite the last value of array and after push the value(myrow[0]=thumb) array showing it's length 7 before it was 8. What is the right way to push value at 0 index value
I got a problem with processing an array in actionScript. I removed the last element of an array through array.pop(). After that I would like to put this removed display-object back to the beginning of the array: array.unshift(object). The object is now the first element of the array but it got still its old label (number of the last element). Therefor I can't update the position (graphically) of the display object. Is it possible to "reindex" the array?
I have my grid-array in my flash game that has a set sized index in it, and through some code it sometimes checks outside of the Array index. Is there a way I can check to see if a index slot is undefined/existent
Gives me a TypeError #1010 public function fnPopulate(X:int, Y:int, Grid:Array){ if (Grid[ X + 1 ][ Y + 1 ] != null || Grid[ X + 1 ][ Y + 1 ] != undefined ) {
var fitb:Array = new Array("question1","question2",[["answer1","t1"],["answer2","t2"],["answer3","t3"],["answer1","t4"]]);
It's for a quiz program. Question1 is the first part of the sentence, the answers words that are shuffled and question2 is the last part. So basically they have to align parts of a sentence in the correct order.
Everything is groovy, but I can't figure out how to check if the words are in the correct order. The current [2][0][1] position is my test for embedding the answers, but when it's shuffled it seems to ruin everything.[code]...
I have three placeholder images, the contents of which are populated by an array ("galleryArray").These three placeholders are titled "placeholderLeft", "placeholderCentre" and "placeholderRight".
the contents of "placeholderLeft" will be: "galleryArray[n-1]" the contents of "placeholderCentre" will be: "galleryArray[n]" the contents of "placeholderRight" will be: "galleryArray[n+1]"
I have a sprite loaded as an array, and that array has an event listener for a function. say that function is called funct1. in funct1, i want to be able to grab the index of the array and load it into a variable for future functions and what not. how would i go about this?
