ActionScript 3.0 :: Omit A Child From Being Rotated?
Jan 20, 2009
Suppose I have a Sprite (A) that is constanly being rotated (as often as the mouse moves).
I have another Sprite (B) that is a child of (A). It makes sense that B is a Child of A because I want B's position to be relative to A's position, and I want B to become invisible when A goes invisible, etc.
However, I would like B NOT to rotate when A rotates. Is there a way to omit B from rotating when A rotates, even though B is A's child?
I know I could do something like B.rotation = - A.rotation everytime A gets rotated, but that feels like a clunky hack to me... there must be a better way?
Currently I'm considering making B a separate object, and not a child of A. But thats not much better because then I have to keep B updated with A's position and visibility, etc...

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.

I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code:
trace(SpriteP.width + ' ' + SpriteP.height); //100 250.
SpriteP.removeChild(Sprite2)
trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good.
When Sprite2 is rotated at 90:

And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.

I am currently reading the Actionscript 3 Bible and the author shows an example in which a custom eventDispatcher class is created. When the class is later used in the code it's called as such:
//Thermometer is a custom eventDispatcher that extends the eventDispatcher class.
var thermometer:Thermometer = Thermometer(event.target); //why no new keyword?
I'm a new programmer and I was curious if someone could explain how this works? Why is the new keyword omitted? When you omit the new keyword on a class that extends another class is it essentially just calling the superclass(eventDispatcher) constructor?

I'm working through a tutorial to create an mp3 player in actionscript. When I delete my first 4 lines of code, the .swf still works great! I thought you needed to declare what classes you're importing for every object you create later on.
import flash.events.MouseEvent;
import flash.media.Sound;
import flash.net.URLRequest;

If I turn 'Omit trace actions' on, then when I run the file, I get the error that says: Stack underflow occurred.
Fortunately, it told me what class it occurred in, so I took out the traces one by one, and I found one particular line that causes the error. It's just tracing a string, and it causes the error anywhere inside of this one function.
So I can easily avoid the error, by either erasing that one trace, or by turning 'omit trace actions' back off. But I don't really get why it's happening.

I have a picture on the stage that has multiple items that have hotspots/links over them that should open a child swf on top of the background and show details about the items. then have a button in the child swf itself that removes the child from over the background so the user can click on another item etc.I found this code in someone's post and I am trying to modify it so that works for multiple swf files...it currently works for a single swf.I wan to pass the name of the button in front of the .swf in the URLRequest to have the same name as the instance name of the referring button. But I can't figure it out. Here is the code I am using on the stage

I am facing a curious issue. Generally when we draw lines in Flash either vertically or horizontally or through exact 45 degrees on either of the sides, they come out as straight and anti-aliased. While if they are drawn deviated from either 0 or 45 degrees, they come out as jagged. I want that to be anti-aliased too

When I select the text tool in Flash and click on screen to type, my text box is default rotated 90Ė clockwise. In addition, the text is default bottom aligned so when you hit return, the next line is above the first line. So, simply rotating it back doesn't
Even my properties box align buttons are rotated: I should add that the little rotation button you see for "orientation" is not the fix- it rotates individual letters.I can't find anything in the menus, toolbars or preferences to change this...

this math isn't working well. I'm using it for a rotated drag and drop (of a tone arm on a vinyl, a kind of abstract turntable simulation). Right now it just moves a bit in the middle of the vinyl (values between 21 and 36, is this degree or what unit is this?), but it should move between the two edges. The problem is that I don't know enough about trigonometry functions. Therefore I can't optimize the math for envisaged behaviour. Does anybody have an idea/tip how I can get a bit more control on the math and its effect? (maybe with more trace functions)

I have created a simple text scroll ( on (release) {object.scroll += 1} and it works fine.
Now the image in the background is slightly tilted so I have to rotate the text box a bit and I do this the text disappeares.
Any Idea how to get that rotated text box visible when rotated?

I have made an application where you can design your own greeting cards. I use matrices to scale and rotate images, and I always need to know what scale the image has.
It works when the image isn't rotated, by taking the value from matrix.a or .d which are the scaleX and scaleY values. But when I rotate the image, using the matrix.rotate() function, the a and d values no longer corresponds to the scale of the image.
How can I get/calculate the scale value of an object that is rotated? And I don't want to scale the image by using the scaleX and scaleY methods.

Quick question which is giving me difficulty, but I'm probably missing something...
How would I create a bounding box for any graphic, which can accommodate the graphic while bring rotated?
Simply making a square with the maximum of width or height doesn't cut it... think for example holding a T..

I am using Senocular transform tool and I have an object on the stage which I can rotate freely using the mouse. What I want to do is "capture" the total degrees I am rotating the object and write in a a text box. For example, if I will rotate the object clockwise 3 times, the text box will show 1080 (360 * 3), if I will rotate the object counter clockwise 1.5 times the text box will show -540 (360 * -1.5).

Say I've got a box that is 218 by 86. If I rotate it to 50 degrees then the width and height are reported as 206 by 222.3. I'm trying to take those rotated values back to the original values and I'm having a bad math day and can't figure it out.

I managed to have a working sample using the Gyroscope native extension. I followed these steps:
1) Downloaded the extension
2) Added the ANE file to the library path into Flash Professional CS 5.5
3) Coded as shown in the extensions documentation
4) Exported the SWF file
5) Compiled the SWF and extension using ADT
I worked perfectly. I had a 3D cube rotated using the gyroscope data. Well, not exactly perfecty because after some time app seems to have lost right direction. But I read this is normal and that you need to use Accelerator to balance this. I'm not worried about this though right now.

I have a container with masked bitmap in it. The scale and rotation of this container changes at runtime, and I need to draw the masked bitmap but cannot figure out the appropriate matrix calculations to do so.My code works correctly to reflect position, scale, offset for centering without rotation. When rotated, the angle is correct but the positioning is incorrect - I believe because the dimensions change when the rectangle is rotated.how to compensate for this in the positioning - here is some code:
// Adjust the transformation matrix to account for the position of the container
var tMatrix:Matrix = _imgContainer.transform.matrix;
//Offset for container

I have a couple of images, representing tents, that look like this: The red and blue parts on each side of the tents are doorways, and several tents can be connected together via these doorways. For example, I want to connect the two blue doorways so that they match up like in this picture: If the first tent is stationary, around which point do I rotate the second tent and how do I calculate where to place it?
Currently, I have the upper left corner of each doorway as an x and a y value, together with the width and direction (in degrees) of the door. I'm treating the doorways as one dimensional, so they don't have heights. Would another representation suit this better? Perhaps a start point and an end point plus direction?

Is there a simple way to take a few square images and set rotationY for each one to be the same degrees, then using an equation line each clip up after the previous one? For some reason the width property of the rotated clips is not lining them up correctly for me. I managed to get the desired result by trial and error (see below), but really need to get an equation for this so I can move the clips around with little hassle.

What does work : I want to put a dynamic textfield on my stage.Then i change the content of this field with AS3.But : when I rate the textfield on my stage, the text disappears.And I have embedded my font (also 'Export for actionscript')...I prefer not to put any textfields on the stage using ASSo the only code I use is : ActionScript Code:this.trial.text = "this is a test";

Here attached a simplified, reduced flash file as an example of my earlier problem. With some trial and error I changed the function rotation2. I changed (180/Math.PI) to (45/Math.PI) to get the mc_arm into the half circle, but it just moves a bit in the middle of the circle when you grab and drag it. How can you optimize this behaviour, so that the arm really follows the mouse on mouse down and move, within the borders of that half circle? The formula must be changed somehow, but I don't know how.

Using textfields. I need vertical text, rotated so that you could read it from bottom up. I can do it with static textfields, but I need to change the content of the textfield, so I cant use static textfield class. What other options are there? I've heard something about embedding fonts does the trick. The thing with embedding the font....I read that if it works, it increases the swf size quite significantly. Atm I am using a very narrow text field with multiline so that one letter is on a separate line, but it doesnt look good and I need to change it.
