i have a bunch of movieclips inside a container movieclip.they all have really crazy coordinates, like x: 1590.24 and y: 696.66443i was wondering - is there an easy way to "quantize" them to round their coordinates to the closest integer?

I'm making an application in actionscript that deals a lot with numbers. One of the problems, which has been driving me nuts for a while now, is "almost integers". Essentially, if I do something like the square root of 3, then square it, it gives me 2.99999999999999 (this is just the easiest example to test with). I've tried forcing it to round to a certain decimal place ([URL]), using toFixed, toPrecision, and math.round.
I've been spending all afternoon on this, and have found that actionscript uses 15 point/precision floating numbers. So with the squareroot/square of 3 above, if I specify it to go to 14 decimal places/significant figures, it gives me 3.0000000000001 (essentially ending with a 1), and if I specify it to 15 digits, it gives me (2.9999999999999).
I'm pretty sure that Actionscript is trolling me, because if the number was 2.9999999999999 (15 digits) and I rounded it to 15 digits... it'd make sense to keep it the same because there is no number after the last 9. However, if I round it to 14 digits, shouldn't the 14th 9 (15th digit) be chopped off, and the 13th 9 (now the last digit) rounded up, and making it carry over until it just becomes 3? Where did the 1 come from when rounding to 14 digits? If there was a 9 before that, shouldn't it have made it round to 3 when rounding to 15 digits?
Is there a way to use Math.Round to ensure that ALL text boxes are on whole number, X,Y coordinates?
View 4 RepliesI don't understand why my number generates more than two decimal places after toFixed is applied. Am I misunderstanding the purpose of toFixed()?
Here is the code (one case in a switch):
Code:
case jewelry:
m_premIncrease = m_premData[m_selectedIndex][0][0] * m_premData[m_selectedIndex][3][0];
trace("Jewelry premium increase is " + m_premIncrease);
m_premIncrease.toFixed(2);
[Code]...
This one seems though, as there isn't even a regular "round-to-specific-decimal" function.. (I know the work around for that though)[code]...

I really need help with my code...okay how to put ".00" after round the numbers in 2 decimal places..this code works well with another numbers but if I'm try with this number it will output the numbers as "9" only.

how do you round a number to 4 digits... so 3.45356345345 is 3.456 and 1 is 1.000
View 5 RepliesI've just made an interactive banner with rollover/rollout commands taken from this site. My problem is now: I still want to create a button with onrelease event such as getURL and clickTAG covering the whole banner. But the button is above the _mc with the rollover/ rolllout events so it doesn't work.

I can get mc_inside._x and mc_inside._y properties relative to the container movieclip, but how can I get the mc_inside._x and mc_inside._y relative to the _root (the stage)?
I'm putting together a site, that has 3 pages and I'd like the content to move into position when the menu button is clicked. So, 3 buttons etc, 'Home, Portfolio, contact" and one movie clip that contains the info. I'm not really a programmer [URL].
View 1 RepliesI have this XML that I want to use to set the position of movieclips placed dynamically on the stage but I am having a hard time figuring it out.This is what I have in my XML:
ActionScript Code:
<STARS>
<STAR XPOS ="93" YPOS = "44"> </STAR>

for some reason whenever i call or define a variable like this:
Code:
onClipEvent(enterFrame){trace(k); k = go._y;}
the trace results in "undefined". dose anyone know why and how to get around this issue? it

Basically there's an object in a movieclip. I want to find the location of that object in relation to the movieclip, not of the object's symbol. So when i and look at the x and y of it, it wont show 0, it will show the x and y location in the movieclip it's in.
View 4 RepliesIs it possible? Has there been a thread on this..
View 5 RepliesI've been scouring the web to see how to do this, and now I'm not even sure it's possible. However, it seems there must be way. What I want to do is create a function that will take x,y coordinates and tell me what MovieClip or Sprite is at that location. I want it to happen automatically, without any MouseEvents or anything like that.
View 8 RepliesI have a problem regarding the x, and y coordinates on a flash project of mine. Whenever I set the x and y coordinates for a movieClip:
Code:
function setPos() {
with (mc1) {
_x = 400;
_y = 300;
}}
The MovieClip never gets sent to the proper coordinates.
I have a movieclip that I am adding to the stage dynamically. The movieclip has to be placed at specific coordinates to match the current text field.The coordinates that show on the INFO tab are x=264 and y= 365. However, in order to get the movieClip to match those I have to set x to 398 and y to 200.If I set the coordinates to those in the INFO tab then the movieclip does not show; it appears off stage.

View 3 RepliesI have a main mc, with another mc nested inside it that needs to reposition to exact x,y coordinates (on four separate occasions). Can I put keyframes on the timeline with a script placed on the keyframes so that when my main movie reaches those frames, the nested mc repositions to the specified coordinates?
View 9 RepliesI am trying to get a movie clip - nested inside another movie clip on the stage - to match the x, y coordinates of the mouse. Attached is an example file both in Flash 8 and MX2004 formats. I can get the drag to occur, but the problem is that the dragged mc's coordinates are relative to it's parent movie clip and not the stage. I have been messing around with localToGlobal with not much luck. I think I may be using it wrong, though. I have left it out of the example file.
Here is the relevant code:
var dragging = false;
this.onMouseMove = function() {
if (dragging == true) {
this.container.drag._x = _xmouse;
this.container.drag._y = _ymouse;
}};

How to position an mc on the center coordinates of another mc embedded inside. inside of my main mc I have an image and mcs above. I want to make a button that says something like: On release center main mc on coordinates of mc inside of main mc. So far I have some code for an on event function:
main_image_mc.onEnterFrame = function() {
main_image_mc._x;
main_image_mc._y;
speed1 = 8;
function moveIt(endX, endY) {

I cannot assign _x and _y coordinates in a movie clip dynamically. For example:
for (i=1; i<=5; i++) {
myThumb_mc = "thumb" + i;
myThumb_mc._x = Stage.width/2;
myThumb_mc._y = Stage.height/4;
}
But if I do:
thumb1._x = Stage.width/2;
this works.
I was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.
I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:
red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);
what i need is to position a Movieclip with coordinates inside a xml file.

source.draw(board);
var bitmap:Bitmap = new Bitmap(source);

I just started coding classes and I am having some pretty good success thus far coding individual objects. BUT I realized that I don't know how to find coordinates of another object that is on the stage!Say I am coding in the class "Zombieguy".With the other movieclips linkage "Armyguy" I try toracetrace(Armyguy.y);ORtrace(Armyguy.Y);Both come up with "access of possibly undefined property y through reference with static type Class".I'm sure this is probably pretty simple, but can someone inform me of how to do this small step that is holding me back?
