Actionscript 3 :: Find Closest Number In Range?
Apr 27, 2010What is the best way to find the closes value in a range...
for example i have an array with 0, 90, 180, 270, 360.And a number 46...
What is the best way to find 90 in the array?

I have to take a number and figure out which "tier" it falls into.For example, let's say I have a table that has three tiers "economy" "typical" "deluxe". From 0-12 is economy, 13-20 is typical, 21-30 is deluxe. My actual table has many more levels, but this is the concept.
What's the fastest and easiest way to do that? I was going to use a switch statement starting with the highest, but it doesn't look like that can be done
So 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.

With AS3 I need to find the closest point lying on this path to another point.
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.

The stage is 1024 pixel and the object 726. I do the following, it works ok but sometimes some part of the object goes of the stage.
menucenter=Stage.width-_root.object._width;_root.object._x=Math.floor(Math.random() * (menucenter - 0)) - 0;
How do you add a range of number within an array? for example my 2 arrays consist of 1-30 and 31-100.[code]...
View 2 RepliesHow would I restrict this variable:
Code:
this.mousePercent = _root.portfolio._xmouse/500;
so that it can't get below 0 or greater than 1?
I have a single line for my XML gallery,that I'm have a few troubles with.I want to tell the gallery that after it has loaded all the thumbnails; to perform a function on the the 5th thumbnail up to the 40th.gal["thumb"+(5+random(40))].gotoAndStop(2);So far, I've just managed to tell it to randomly select any thumbnails from 5 to 40. I need EVERY thumbnail from 5 to 40.
View 2 Repliesim sure its an easy one:
var tstArray:Array = new Array(1,2,3);
for (var a:uint=0; a<tstArray.length; a++)
{
var x:Number = Math.floor((Math.random()*tstArray[a]));

Need to send a user to different frames depending on a number input into a text field. Here is what I have, but regardless of number, it send them to Frame 20. New to AS and having a tough time figuring this out.
var HDLrange:int = int(enterRange_txt.text);
enterRange_btn.addEventListener(MouseEvent.CLICK, onClick);
function onClick(event:MouseEvent):void

I'm trying to syncronize an audio and some text by highlighting it. In the main movie I have counter variable which calls charCounter3.as and timeVars variable which calls timeSettings.as I have onEnterFrame function that highlights the text while sound is playing.
My code is:
function onEnterFrame(e:Event):void {
pos=soundChannel.position;
var minutes:uint=Math.floor(soundChannel.position/1000/60);
var seconds:uint=Math.floor(soundChannel.position/1000)%60;
debug_txt.text='position: '+pos;
[Code] .....
Highlighted text needs to be updated on audio forwards and backwards. I think onEnterFrame isn't being able to catch the timeArr values.
I'm trying to come up with a function that can give me an array of unique random numbers based on a range. If they don't fit within that range then it keeps check until it return the correct array of numbers.
Unfortunately I just keep getting an constant loop that crashes flash.
ActionScript Code:
var positions:Array = [];
function uniqueRandomNumber(max:Number, min:Number, len:int, range:int = 100):void
{
[Code].....
uniqueRandomNumber( 200, 0, 6, 40 );
I want to make sure that all numbers are 40 apart from each other
How would one produce a random number, ranged from say, -100 to 100?

Create a 12x9 grid;Populate the cells with random numbers ranging from 1-9;Assign a symbol (custom graphic) to each cell depending upon which random number is generated in it;Limit the amount of times each number in the random range is used to 12.My question is simply this: how do I, using AS3, create a random number function that will only use each number in its range a maximum of 12 times (it is important to note that my grid consists of 108 cells using the numbers 1-9 exactly 12 times each)? So for example, if the random number function populates 12 cells with the number "4," it will then exclude that number from its remaining iterations.I am adhering to OOP standards so including script in actual timeline frames is not desirable.
View 5 RepliesI know the problem has something to do with the string vs number issue and I've tried a few things, but can't figure it out.

really great job done in the forum This is my first thread here, and i would like to ask how can someone produce a random number within a complex range.In my case i want to produce a random number in the range [0,90]OR[270,359] and i can't find the way to do this using Math.random . I looked on the internet but in most cases a simple range is used like (2,40) or [4,50] etc.
View 14 RepliesI have an object which I want to rotate between -45 and 45 degrees, but I want that to be based on the mouse position. If the mouse position is at zero, I want the object to be at -45 degrees. If the mouse position is at the stageWidth, I want the object to be at 45 degrees. How would I accomplish this?

View 5 RepliesI recently bought a new machine and tried to put my Flash 8 software onto it. The serial number was fine, but it requested the serial number of the software I upgraded from, which I no longer have (MX, I think it was. I threw it out ages ago thinking I didn't need it ). I can't even remember what email address my macromedia/adobe account was under, it might even be under an email address for a domain I no longer have.
I do still have the software installed on my old PC. Is there anyway I can find out the serial number of the MX I upgraded from off of the Flash 8 on there? Or it is a lost cause?
How can i find the square of a number?
View 5 RepliesIm looking to be able to find a number (any number) within a text string, what i ultimately want to do is crop the number out of the string to just be left with a number value, the only problem is the string could be any length and the number doesnt necessarily start at any point from the last characterI have items on the stage named 'image0', 'textfield2', 'button500' etc, as you can see the prefix before the number isnt a fixed length so I couldnt use substr and set an index, and since the number could be any number i couldnt set the index as a certain value before the end of the string. (ie it might return '500' or 'ld2' or 'ge0' in the examples given before)

For example, my string is "0 1 3." I want to check to see if the number 3 appears within this string.
I need to check if a number is negative and if so, trace "true" and if not "false".
