I have an array filled with hundreds of numbers.I want to write a function that gets passed a number and searches my array for the closest value in the array to that number.
View 1 RepliesSo if the value of myVar = 50;..and the array holds the values 25, 100, 150, etc.I want to write a function that will be able to find the array element that's closest to myVar, which would be the first element in the array (myArray[0]), since 25 would be the closest value to 50.

I've got a grid of sprites.Now I would like to drag an image on a grid-element.Therefore I need to know which x/y of the grid-element is the closest point to the mouse-position.
View 2 RepliesI have a path drawn in the flash IDE, accessible as a MovieClip.
With AS3 I need to find the closest point lying on this path to another point.
I'm not sure what this is called, so have Googled but am struggling.Imagine a line of 5 movieclips, user clicks one, it moves +10 pixels in Y. Then, the next two closest movieclips move +10 in Y, then the next two closest to those 2 move, etc etc.
That's what I want to achieve, but I don't know why to start researching. I could get it working in a very ugly way with mess code, but I'd like to make it as clean as possible.
How would I go about finding the closest instance to a certain spot? I was thinking about using the distance formula and looping through all the instances on the stage, but I don't know how to find the shortest distance between all those measured.

View 0 RepliesI'm trying to make it so that there are a bunch of instances (let's say 20) that move around about the stage. There are also 5 other instances (let's call them followers) that move and rotate towards the nearest of the 20 moving instances. I achieved this with this code in an ENTER_FRAME event:
PHP Code:[code]....
This code is placed in the class file for the follower objects. The problem is that I don't want more than one follower following the same movieclip. I was thinking that after the for loop I would remove c (the closest movieclip and the one it is following) from _root.eArray[0] and put it in _root.eArray[1] so that the other followers would not count it when searching for the closest.
I want to prevent users from using webcam emulators, I have done that in AS2 by using senocular's function, but I can't make it work in AS3,so, here is the old version by senocular , and I would like to do the same in AS3, tried using indexOf but doesn't work, I need to find at least the first 4 characters of the string and compare them to the item inside the array in AS3![code]...

View 3 RepliesI have a big array which contains words and sentences. I want to find certain specific words to replace with other words. I know about the string replace(), but from what I can understand, that only works with strings. I'm looking for something similar to the str_replace function in PHP where you can search both arrays and strings, and change words in them. Does something like that exist in actionscript 3, or do I have to build some kind of loop myself, to loop through the entire array, and use the string repace() on every single string in the array?

i've been working on a problem for a while now, which involves targeting the closest movieClip in relation to the x y coords of the mouse, I've attached a nice little acompanying graphic.Each mc added to the stage has it's own sub-class (HotSpots) which uses Pythag to measure distance from mouse. At this stage i can determine the closest value from my Main class but can't figure out how to reference it back to the movieclip... hope this makes sense. Below are the two Classes.My Main Class which attachs the mcs, and monitors mouse movement and traces closest value.[code]

i don't understand arrays in functions, but how do you find the matching items given in an array? for example:
var fruit:Array = ["apples", "oranges", "grapes", "oranges", "apples", "grapes"];
how can i get it to show only the number of apples in the array?
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.
View 1 Repliesin my program the user can create multible movie clips so i stored them in an array. now the problem is i need to find the ._x of all of them. so i have tried to create a for loop that will go through at a certain amount of times (pending on the number of created movie clips)
Code:
for(z=1;z<=_root.howmany;z++)
trace(array_name[z]._x);
}
it doesn't work?
the array is storing the string of the movie clip
(like; _root.moive1, _root.mave2,etc)
but when i try to access it, it doesn't work? what am i doign wrong and/or what should i do?

View 7 RepliesI'm working on a project where I have an array of coordinate points (4 of them) and a menu system that, when clicked, rearranges the boxes so that they all move around. The problem is that the values I pull out of the array are not always unique so some of the items end up not moving (or sometimes it ends up moving two to the same spot because the last one didn't move and one of them moved to a spot that is already occupied).
Here is the code I was using which for the most part works, except as mentioned, sometimes the check for the last one in the loop sees that the conditional is not equal so it doesn't do anything because there is no other values to loop through and it just leaves it in that spot.
Code:
private function checkCoordinates($item:MenuItem, $coords:Array):Void
{
var numItems:Number = $coords.length;

Essentially I need the MC to know whereabouts in the Array it is
Say you pick a movieclip at random, and assign in a function, how do you find out what number in the Array it is and remove it from the array?
For example...
Code:
for(a=0; a<arrayInQuestion.length; a++) {
if(arrayInQuestion[a]!=this) {
if(dist>50) {
[Code]....
But of course, "this" doesn't work, so I need to find out what number "this" is
Of course, it would be easy to remove the MC that I am checking "this" for distance with, it would just be splicing array[a], but it's "this" that I am just not sure how to splice.
