I'm trying to just make an image center horozontally in the page when I addChild it. I figure the formula I need is the width of the of the image deducted from the width of the page divided by two... but I don't know how to make that into a formula, as in I don't know how to represent the size of the newly added child in the formula. Code is below.

I have downloaded Box2d ([URL]) and created a project that looks like this: [URL]. catalyst is the green cube and it has the base class "shapes.box", it is inside "world" which has the base class "wck.World". What i want to do is to add another "catalyst" from the library inside "world" when i click on add_btn. I tried to accomplish this by this code:

I am trying to make a series of Movie Clips that lay next to each other on the X axis that will alter their _x value in accordance with the MC next to it. ie. When the width or _x value of the MC to the left increases the _x value of the MC changes.

mc_1._x = 0;
mc_2._x = mc_1._xscale;
mc_2.onEnterFrame = function(){

I'm trying to dynamically set the addChild linkage identifier, but am having little luck.
Code:
for(i=0;i<6;i++){
if(i==this.myId){
var section:MovieClip = "section"+i

}}
In AS 2.0 I could simply do this:
Code:
attachMovie("section"+i, "section",0)
I've come across something strange. In the game I'm building I have hearts representing the lives which th player has. I add and remove them from stage with add/removechild command. But for some reason one or more of the hearts gets a different visual size then the rest. I've traced out the size and it all matches. They are all width 25 and height 30, just as they are programed to be in my class.
Edited with code added.
Code: Select allpublic class RetroGameClass extends MovieClip
{
/*!-----VARIABLER------!*/
var heart1:Heart = new Heart();

We are supposed to build a game, and each of us is to make a level. So we did, but integrating them is giving me issues. Specifically, each of our levels are contained within a symbol. I personally have a ton of symbols that point to eachother already (main.as, menu with various elements, level one, boss level) but for whatever reason whenever I try and addChild my partner's level it gives me "TypeError: Error #1009: Cannot access a property or method of a null object reference."
the way I've been doing it looks like:
var levelTwo:SkiHill = new SkiHill();
parent.addChild (levelTwo);
parent.removeChild(this);
like I said, it's worked every time Ive used it between my own things. My partner's is a no-go. If I just slap his level on the stage and go it runs fine, and it will properly add/remove child to transition to one of my levels.
All I can think of is that I've checked all the names. I also noticed my partner didn't use an ADDED_TO_STAGE event listener, but adding that didn't help at all.
I am attempting to make a class that handles the building in a game, but I can't get the object to come on stage. I can get everything to work if I am on the timeline, just not from this class. I've been getting this:

what I'm trying to do :I have create a new class called Graph and make it extends Sprite and add a scroolpane to my stage and make an empty movie clip called content_mc and make the source of the scrollpane equals to content_mc
in the first frame i wrote this code
import Graph;
var graph:Graph = new Graph();content_mc.addChild(graph);
This is the third thread I've written for my current project (1st was answered perfectly, 2nd failed [but I still figured it out anyways]) but I'm not sure if there is a solution to this problem. I can't really explain my problem, so once again I've included a helpful animation to show you what I mean. Bear in mind that the pale-blue box represents the movie clip's borders, and those borders are usually changed to include the animation (instead of the borders moving with the animation, the borders get bigger).
For the animation problem, I've already got a solution: create an invisible movie clip that has the exact size and shape of the animated movie clip and make it follow the movie clip as it animates, and make the hitTest check the invisible movie clip instead of the animated one. As for the rotation problem, well, I don't know how to fix it. Is there a way to change that?
I am trying to code a loan calculator into Flash, however AS3 doesn't like my formula and won't calculate it, can someone help? Here is what I have:
loan=15000
apr=13
term=48
var loan_amount = (apr + (apr / (Math.pow(trm, (1 + apr)) -1 ))) * loan;
When I print out the loan_amount I get a 0.If I do: var loan_amount = (Math.pow(trm, (1 + apr)) -1); it will give me the result 1.0331079714165e55
As soon as I add the next part of the equation (apr / (Math.pow(trm, (1 + apr)) -1 )); it will give me the actual apr value as the result instead of the apr divided by the 1.0331079714165e55.Likewise, if I try to add a fixed value instead of the apr variable, it will return that fixed value instead of doing the math.
i have a game inwhich a bait is thrown determined by a variable of a power meter, when the meter is full it returns a variable of 1 when half 0.5 and when low near 0, how can i use this to determine how far my "bait will be thrown" onto the screen? i have tried how ever the X value would not be consistent with my fishing rod placement, and when the point is decided i will have to move my bait to that point and stop.

Is it possible to load mathemetics formula in flash as3 dynamically.
[Code]...
First note: mathematically, I'm not that skilled at all. I played a game on iPhone a while back where you press a point, and an arrow fires from your castle which will always intersect the point you pressed. I wanted to make a similar game, thinking it would be an easy quick make; then I ran into the realization that the mathematics for this is actually beyond my skill level.
I'm assuming they're using a parabola formula or something which would determine the velocity and angle needed when the arrow is launched for the arrow to always intersect the clicked point. I only vaguely remember how parabolas work from school and have no chance of working out any formulas.
[Code]...
Well, see this simple example:
Code:
var a:Bitmap = someExternalBitmap;
addChild(a);
a = someOtherExternalBitmap;
[Code].....
My code is an external .as file. Google provides this code on their demo, which contains the this keyword:
[Code]...
Notice that I have 4 calls to console.log. The first 3 fire, but after the new GATracker statement, the 4th does not fire. I have a feeling that I'm overriding the entire package with the object created from new GATracker when I should be passing a different context. I believe the correct context I should pass is whatever this defaults to when not inside of a package/external file, I assume it references the main stage object.
I'm trying to have a class file which can add objects to the stage via addChild; however, when I call addChild from within the class file, I get the error "1180: Call to a possibly undefined method addChild." I've tried importing flash.display.* and that doesn't fix the problem. Does the class file have to extend Sprite or MovieClip to be able to add objects to the stage?
View 8 RepliesHow to convert 3d point to 2d point? I've found next formula in Internet(camera is situated in origin)

But these formulae give me strange result when z are less than zero(z<0) I need build line from A(100,100,100) to B (100,100;-100) As you can see these equations give really strange result when I try to convert B point in 2D dimension
I have the followings:
_p:Player (which is a MC)
a1:Animation1 (which is a MC)
_p.addChild(a1); //doesn't display anything
_p.stage.addChild(a1); //displays a1
Why won't the MC display a child without using his stage?

The newMC doesn't show up.If I add 'parent.' in front of the addChild then it appears.mc_LibItem has a base class of "flash.display.MovieClip" and is exporting for ActionScript and on frame one.For grins I created a new .fla and began messing around with the same addChild idea and it worked.
I'm having a real problem trying to work this out...
A: I start with a movieclip on stage. it's 100x100.
B: I set xscale and yscale to 150.
C: I use "attachMovie" to add a little man into the square.The problem is, the man has an xscale of 100, but he is also scaled with the movieclip square container. So he appears too big.
D: What i would like to know, is what formula you would use to reduce his scale so he is the correct height, if the container movieclip had an xscale of 100?

I need to calculate the value of a formula which is passed dynamically by using text box.This formula contains a set of variables which are already declared and assigned a value(hard coded). I will provide a submit button , on clicking this button I must be able to evaluate the formula that I have passed dynamically using the text box.
View 2 RepliesI've been trying to look this up but not had any luck so far. I'm trying to make a simple pseudo-3D app, but I'm stuck on how to pull off the movement. If I have an object with x,y,z coordinates, and its movement speed, pitch, and yaw, what formula would I use for movement? So for example, if the object is at 0,0,0, moves 6 units per frame, and has pitch 30 degrees and yaw 15 degrees, what will be its coordinates next frame?
View 1 RepliesI built an app in flash where you can rotate objects and save positions and rotation to xml.... that xml then feeds html to produce a layout that is then rendered the a pdf It seems that every time it goes to the html, a rotated object in positioned a little to the lower right then the position in flash.
I know the rotation in css in different, but I think if I can find the true top left of the rotated object in flash and pass that it will solve the issue.
I tried this
newx = imageHolder.parent.localToGlobal(new Point(imageHolder.x,0)).x;
newy = imageHolder.parent.localToGlobal(new Point(0,imageHolder.y)).y;
also this imageHolder.parent.globalToLocal(imageHolder.localToGlobal(imageHolder.getBounds(imageHolder).topLeft));
neither work. Is there something else?
I have a little math problem with a game I'm making, and I can't for the life of me figure out the formula needed to accomplish something..Say, there's a sniping game, and a BIG image that must scroll from left to right according to the mouse movement.
Something like this:[URL]... In that example, the scene is 550 pixels wide, and the image is 1100, exactly two times the scene, so the formula is kinda easy..
[Code]...
the center of the image would be at x 1500, way over to the right of the scene, outside it, but it would fit inside the screen, like this (the blue square represents the real size of the scene):[URL]..Then when the mouse is at the far right side, that is 550 x, the image center should be at -950 x, like this:[URL]...
I'm not that good with Math and i have a formula for a that it's universal from what i understood but i dont know how to transform it to work with Flash's Math API.
View 2 RepliesI've been searching for the formula used intrinsically in Flash but I couldn't find anything. Does anybody know how the result colors are obtained when the 'layer' blend mode is chosen for the upper object? I thinks it's done separately in each channel using the transparency values.There might be some bitwise operations going on there but I'm not sure.

View 2 Repliesi'm trying to dynamically layout a calendar using actionscript and i'm no good at determining algorithms to quickly and efficiently lay things out.what i want to do is set it up per the image attached:
* where there are 7 columns and a varying number of rows.
* the top row has the 2 arrows and the month and year display.
* the second row has all the day headings, i.e. S, M, T, W, R, F, S
* and the rest of the rows will have the dates.
how do i come up with a nice clean formula to calculate the positions so all these elements align?
So ive been asked to build a page for a real state company and the guy told me it should be similar to these [URL] Ive been trying a couple of weeks so far, but i dont seem to find a way to do somthing similar, i mean, i want to have the welcome screen as those two:
- the gradient background
- flash occupies whole screen no matter what size it is
- gradient expands sideways infinately
- no matter what height my explorer window is, gradient is always in the same position relative to top, and if i keep expanding downwards the background keeps last colour of the gradient.
- the brand logo looks as if it had top, left and right anchors, and it also limitates the minimum width of the explorer window
i though of addind a 3000 x 3000px square with the gradient and centering it, but i know there has to be a professional way of achieving that.
