• Math.Random () does not work in BB

  Salvation;

  I just want to ask if the BB API, can give the possibility to generate a number of random if yes how can I do; generally in java J2SE: I CAN DO THIS:

  choice = (int) (Math.Random () * 3 + 1);

  "to generate a random number ' 3 nomber.

  I try to do whit BB I import java.lang.Math;

  and when I try to put Math.Random (), it does not work

  can anyone give me the solution?

  in fact I want to have a HEX number, I think I have the Random one after I'll transforms in HEXA.

  Thank you very much

  Here is exactly what you need to get a random number

  first import

  import java.util.Random
  

  then

  //Random number generator
      Random dice = new Random();
      int num = 0;
      for (int counter=1; counter<=1000; counter++){
          num = dice.nextInt(1000); //it will generate numbers up to 1000
      }
  

  You are welcome!

• Math.Round () and Math.Random)

  Hello

  Do we have the equivalent methods in J2ME for Math.round () and Math.Random ()? I could not find in Java.util.Math or net.rim.device.api.Math

  Thank you.

  Reshma

  @ JavaMEUser, you can write your own class of math for your application, use the following code...

  public static int round(float f)  {     return (int)(f + 0.5F);   }public static long round(double d) {                return (long)(d + 0.5D);   }
  

  Thank you!

• help with if else statement and math.random

  Hi a little new to js and need to fill in a text field with the text selected randomly from a range when a button depending on what is put into another text field that is also randomly.

  I really hope that makes sense but here is code that I got so far

  var bg = this.getField("Background").valueAsString;

  var pt_sage = new array();

  pt_sage [0] = 'of the text based on background. "

  pt_Sage [1] = 'of the text based on background. "

  var i = Math.floor (2 * Math.random ())

  var pt_hermit = new array();

  pt_hermit [0] = "text".

  pt_hermit [1] = "text more»

  var v = Math.floor (2 * Math.random ())

  If (bg == 'Wise') {}

  this.getField("PersonalityTraits").value = pt_Sage [i];

  } else (bg == 'Hermit') {}

  this.getField("PersonalityTraits").value = pt_hermit [v];

  }

  I hope someone can help and thanks in advance

  You must change this:

  var pt_sage = new array();

  To do this:

  var pt_sage = new Array();

  Better yet, change it to:

  var pt_sage = ["a text based on the merits," "a text based on the"];

• Is it possible to use math.random to generate the name of the item web app?

  Math.Random () can be used to auto fill in the name of an element of web application field? I have a client who needs web app point briefs to be random and we do not ask the user to have to create a name for their presentation.

  I think that I thought about it. If anyone is interested:

  I should add that if you try to do, make sure to place your script AFTER the element, you want to be pre-populated. Otherwise, the script will be executed before the load element and it won't work.

• parameter constraint and math.random height

  I'm a newbie script. I'm doing a script that will...

  1. Take all the items I chose
  2. Scale them down (in height) randomly between 30% and 100% of their original height.

  Here's what I have so far...

  get all the objects currently selected in the document

  selectedObjects var = app.activeDocument.selection;

  reduction of their size by a random number between 0 and 70%

  for (var i = 0; i < selectedObjects.length; i ++) {}

  Gets the height of the current object

  var myHeights = .height selectedObjects [i];

  take the height of the current object and scale of a random percentage

  selectedObjects [i] .height = Math.floor ((Math.random () * myHeights) +. 3);

  }

  And this is what he does, which is excellent...

  

  But there are two problems, in that I am running...

  [Problem] The height is get scaled compared to the document instead of by the object report. I would like to be able to rotate the object about an axis manually before running the script and still evolve each individual height compared to each object. So far, my script is scaling compared to the document x, y (I think).

  

  I put the pivot point for each of the rectangles in the bottom center, but no dice. In the script, how can I say to use the anchor point of the object to the scaling instead of the document?

  [B problem] I cannot compel the math.random to my values. For example, notice here

  

  that one of the rectangles eventually teeny (less than 30% of the height of the original). How to set constraints on the math.random so that it is easy for me to adjust the settings? Right now I use math.floor but I'm obviously something wrong.

  Any idea?

  I did a quick search and found a function to get a random number.

  Resize allows you to change the height rather than change the height property, which will take care of the problem B.

  //get all the objects that are currently selected in the document
  
  var selectedObjects = app.activeDocument.selection;
  
  //decrease their size by a random number between 0% and 70%
  
  for (var i=0; i
  for [A] problem, I would use a different approach. I would start with 1 item (since they are all the same) and duplicate, resize it and turn it as many times as I need to close the loop. We can use a fixed point by using these methods.

• Math.Random in a document with Flash Pro class

  Hello.

  in a previous discussion, I had help with randomization of the position of the "appeaance" on an mc on the stage (http://forums.adobe.com/thread/946317?tstart=0), with code is in the file Flash Pro.

  Here, I ask help randomizing positioning using Math.random but by using a class of documents, in order to avoid rewriting the code for the film of many clips I have in the library.

  Clips in the library begin and end with about 15 blank keyframes: they have 2 layers, one for action script and the other for the graphics (which are also filmed sequences,) while the level of the AS in the video clip is longer than the layer containing art, on both ends, beginning and end, so the effect is of bubbles popping up and appearing on the stage in random positions.

  In the library movie clip symbols have a base popBubble.as class, who works at removeChild (this).

  However, using RandomPosBubble.as in the class of document of the flash file, I get a script error-

  D:... RandomPosBubble.as, line 17

  1084: syntax error: expected rightparen before the colon.

  See RandomPosBubble.as below

  package

  {

  import flash.display.MovieClip;

  import flash.events. *;

  SerializableAttribute public class RandomPosBubble extends MovieClip

  {

  public void RandomPosBubble()

  {

  this.addEventListener (Event.ENTER_FRAME, onEnterFrame);

  _spoboyle said - this will set up a listener for the enterFrame event.

  Each image we check if the MovieClip is on frame 1 and if so recalculate its position

  }

  private void onEnterFrame(e:Event):void

  {

  var mc:MovieClip = e.target as MovieClip;

  If (mc:currentFrame == 1)

  {

  MC.x = Math.random () * stage.stageWidth;

  MC.y = Math.random () * stage.stageHeight;

  }

  }

  }

  }

  Thank you.

  the example that I have running does not produce the same model whenever they appear

• Math.Random)

  I want to create a random number between-3 and 3

  In ActionScript, Math.Random () returns a number greater than or equal to 0 but less than 1. Another way to express that is (0<=  n="">< 1)="" where="" n="" is="" the="" number="" you="" are="" looking="">

  To configure a number to fall at random in a range of numbers, use the following format:

  Math.Floor (Math.Random () *(1+High-Low)) + low;

  High is the largest number in your range and low is the lowest number in your range. For example, to get a number between 10 and 50, my line of code looks like this:

  Math.Floor (Math.Random () * 41) + 10;

  This should work for what you want to do:

  
  Math.Random () * 3 - Math.random () * 3;

• Explain the math random please

  I am completely confused about exactly how works Math.Random (). Mabye I'm looking for an incorrect code to a random number generator. Could someone please post a simple code which will come with a random number and then show one that number? And then if you could, please explain this code works. Just so I don't have to come back and ask one of these stupid questions! Thank you!

  var r:Number=Math.random();  r is a random number between 0 and 1.

  var s:Number = n + (m - n) * r;  s is a random number between n and m.

• Avoid Math.Random () of closure of twice the same number?

  I'm playing a random image gallary by stops to image different every few seconds, and the stock is completely random.

  The problem is, since it has only 5 different images (5 images), I display, there is a high probability that remains to the same frame, how to avoid that? As to avoid staying in the same page twice, if it's not run the new service...?

  You compare the random value with the current value in your if.  Keep your selection of random frame as a separate function that you can call when you need a new random value... as in...

  var preValue: uint;
  var randomFrame:uint;

  function setRandomValue (): void {}
  randomFrame = Math.floor (Math.random () * 5) + 1;
  }

  function createItems (): void
  {

  while(preValue == randomFrame)
  {
  setRandomValue();
  }

  preValue = randomFrame;

  var RandomImg:randomImg = new randomImg();

  RandomImg.y = 100;

  RandomImg.x = 180;
  RandomImg.gotoAndStop (randomFrame);
  addChild (RandomImg);

  who will work on webpages when updated, but I need it to operate when a button is pressed and displayed in a text field in my pdf

  I'm a total noob with javascript only to start learning today so as much help that pos will be great thanks in advance

  Instead of this line:

  document. Write (r_text [i]);

  You need to use something like this:

  this.getField("Field_name").value = r_text [i];

  Or if you use it as the custom text field calculation script:

  Event.Value = r_text [i];

• Is there a way to create a math.random that don't overlap movieclips?

  Hello

  In fact, I have two questions. I create a sequence memory game and I was wondering:

  1. is there a way to movieclips random position on the stage without overlap?

  2. is there a way to have flash draw a vector from one clip to another in the order, and then create a user trace what flash has done? I have 6 clips on the stage, each with their own instance (e.g. obj1_mc, obj2_mc, etc.). Is there a way to tell flash always draw a line between movieclips in sequence, even if the clips are placed randomly on the stage?

  Thank you

  JO

  you don't know.

  1. the best way to position objects without too much running, IF you can assume it will always be possible, is to use something like:

  var mcA:Array = [your movieclips]

  var: index: uint = 0;

  positionF();

  function positionF() {}

  assuming that the points of top-left reg of your movieclips

  mcA [index] .x = Math.random () *(stage.stageWidth-mcA[index].width);

  mcA [index] = Math.random () *(stage.stageHeight-mcA[index].height) there;

  var hitBool:Boolean = false;

  for (var i: int = 0; i<>

  {if (mcA [index] .hitTestObject (mcA [i]))}

  hitBool = true;

  break;

  }

  }

  {if (hitBool)}

  positionF();

  } else {}

  index ++;

  If (index<>

  positionF();

  } else {}

  localization complete.  No matter what

  }

  }

  }

  2. you can use the graphics class to draw dynamic lines.

• Table Math.Random &amp; Delete?

  Can someone help me with the following random number script?

  simplified example:

  I have 10 dynamic textfield to display numbers. named myNumber1_txt, myNumber2_txt... myNumber10_txt

  I have 100 numbers

  //

  for (var i: int = 0; i < 10; i ++) {}

  Result: var number = Math.floor (Math.random () * 100) + 1;

  trace (Result);

  }

  myNumber1_txt.text = "" + result;

  etc.

  //

  This works great – but what I'm trying to achieve is to delete the number that appears already in one of the object textfield, so no double numbers are disclosed.

  so, if myNumber1_txt.text = 10, that 10 will not be calculated the random number more in the rest of the textfields and so on.

  Is there an easy way to achieve this?

  I tried with the delete table... but is not well run.

  Thank you!

  Play with the following code... basically you fill a table with figures, tests to ensure that the value is not already in the table.

  var randNums:Array = new Array();

  for (var i: int = 0; i<10; i++)="">
  var randNum:int = Math.floor (Math.random () * 100) + 1;
  If (randNums.IndexOf (randNum) ==-1) {/ / don't NB in the table so add and assign to textfield}
  randNums.push (randNum);

  This ["myNumber" + (i + 1) String "_txt"] .text plus String (randNum);

  } else {/ / already number in the table}
  i-- ;
  }
  }
