ActionScript 3.0 :: Calculating A Coordinate From A Distorted Rectangle?

Nov 5, 2009

I have a rectangle that I can calculate the corners of and I can detect a point within that rectangle, how do I determine the 2D-coordinate of that point if I were to try and project it on a non-distorted rectangle?

I've tried many a Google search dealing with 3D Projection and and matrices, but I don't even know if I'm looking for the right things.

ActionScript 3.0 :: Calculating Position Of Rectangle Corners

Jan 14, 2010

i'm in the middle of attempting to write my own collision detection algorithm because the built in 'hitTestObject' function seems to be incredibly inaccurate (it's registering 'hits' when the objects are still a considerable distance from each other).I need to be able to calculate the position of each of the 4 corners of a rectangle, based on its rotation. Obviously one of the corners will simply be the rectangle's x and y coordinates. I have made a little test program to make sure I am calculating the positions of the corners accurately - it works when the rectangle is rotated to 0, 90, 180 and 270 degrees, but produces strange results for any other angles.[code]

ActionScript 3.0 :: Dynamically Calculating Bounds Of A Rectangle?

Dec 15, 2010

I am creating an app that has to load a image or swf on to the stage and dynamically place and position it on either sides of the stage i.e. (top, left, bottom or right).how can I dynamically calculate the remaining bounds of the stage using the bounds of the dynamically placed loaded image/swf. ?e.g if the bounds of the loaded clip isRectangle(x=10, y=10, w=250, h=800);What is the remaining Rectangle() to use ofRectangle(0,0,1024,800); ?

e.g if the bounds of the loaded clip is

ActionScript 2.0 :: GetBounds() - Get A Movie Clips Coordinate Bounds And Use The Minimum And Maximum Values Of X And Y To Draw Rectangle Around The Object

Apr 11, 2007

I'm having a little difficulty getting to grips with the getBounds() Movie Clip function. I assumed the getbounds() method simply got the boundary coordinates for the movie Clip, that one could use to draw a rectangle. This is what I'm trying to do;I'm trying to get a movie clips coordinate bounds, and use the min and max values of x and y to draw rectangle around the object. Simple right? But in my case, I'm getting some unexpected results. I wonder does ther registration point of the object determine the coordinate values? Also are the coordinate values local to the clip instance or global to the stage?

Android :: Calculating An Angle Using The Law Of Cosines, Given 2 Points And Calculating 1 Point?

Dec 27, 2011

I am developing a game for mobile in AIR (as3). I have created some bots for this game that initially just wander around. But when a bonus enters the stage, they have to move to the bonus.The detection of a new bonus and moving of the bots works fine, but there is something wrong with the manipulation when a new bonus enters the stage.Basically, this is how it works (or I try to make it work):My bot moves along with his rotation as a parameter. (works fine)

private function moveToNextLocation():void
{
var angle:Number = _rotation * 0.0174532925; // 1 degree = 0.0174532925 radians
var speedX:Number = Math.sin(angle) * _speed;

Actionscript 3 :: Scrollbar With Sprite And Rectangle Won't Move Text, Just The Rectangle It's Painted On?

Mar 8, 2010

For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.

So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?

ActionScript 3.0 :: Creating A Rectangle Inside Of A Rectangle?

Jun 26, 2010

I would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.

I know how to create rectangles with:

Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);

But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?

I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?

ActionScript 2.0 :: Z-depth On Already Distorted Mc?

Mar 8, 2006

I've got an isometric view of a flat surface. On this surface there are various characters running around and I obviously need to control the depths of each object.

My flat surface needs to be used in two views: top-bottom + isometric.

The original mc is generated in the flat top-bottom mode. For the isometric view, that same mc gets distorted: this way the whole XY coordinates system gets distorted too.

Have a look at this (updated).

So i'd need to create this extra coordinate (is it the classic Z-depth?), and manage to gather information about it...

Does anyone know what the formula would be to calculate the depths of each character (red lines)?

IDE :: CS4 Sound Distorted When Publishing From Mac?

Jul 2, 2010

I recently switched to using a MacBookPro (snowleopard) when developing, after several years of PC use. Now, quite often when publishing my swf:s, embedded sounds get all distorted and filled with loud crackling sounds when running the swf (yes, even on different computers). I tried different compressions, bitrates and qualities with the same result. Something is clearly wrong with how my machine compresses sound.

Flash :: Coordinates In Distorted Grid

May 31, 2010

I have a grid in a 2D system like the one in the before image where all points A,B,C,D,A',B',C',D' are given (meaning I know the respective x- and y-coordinates).I need to calculate the x- and y-coordinates of A(new), B(new), C(new) and D(new) when the grid is distorted (so that A' is moved to A'(new), B' is moved to B'(new), C' is moved to C'(new) and D' is moved to D'(new)).The distortion happens in a way in which the lines of the grid are each divided into sub-lines of equal length (meaning for example that AB is divided into 5 parts of the equal length |AB|/5 and A(new)B(new) is divided into 5 parts of the equal length |A(new)B(new)|/5).The distortion is done with the DistortImage class of the Sandy 3D Flash engine. (My practical task is to distort an image using this class where the handles are not positioned at the corners of the image like in this demo but somewhere within it).

Professional :: Static Text In A MC Appears Distorted

Jan 15, 2010

I created a site for a client and they are experiencing something weird with the top links in the base SWF. The links appear to be distorted or doubling up. I don't have anything extra in the MC. And what's worse is that I can't see this effect on any of the computers I have. They see it on their laptop.

I've attached a screenshot from them.

Professional :: Why Is Audio Overly Compressed And Distorted

I have imported voice-over into my flash animation project as a WAV file. When I test it within the library, it's perfect. When I play it back using "Play" under "Controls" it is slightly degraded. And then when I play it back using "Test Movie in flash professional" under "Control" and when I publish the file, the audio is severely compressed and distorted. Why does this happen and how do I fix it?

Actionscript 3.0 :: 3d Rotation From External Swf Gets Distorted (Flash CS4)?

Feb 5, 2009

I have created a 3d rotation along the timeline inside a movieclip using the 3D rotation tool new to CS4. This movieclip resides inside an swf that will show a number of instances of this movieclip. The 3d tranformation works great when running the swf. BUT! When the swf gets published and I want to load the swf inside a main swf the 3d transformation gets distorted and out of place. Iīve looked at perspective projection and stuff like that, but I canīt figure out how this is effecting a timeline based animation and what I can do to stop it.

ActionScript 3.0 :: Button Hitarea Is Off/ Distorted (weird)?

Aug 13, 2010

Got this weird issue going on today. The hitarea, the 'interactive space' of some of my buttons is off/ distorted. I created several buttons in a class with the pen tool and converted them to Buttons. I added some eventlisteners, but when I tested my Movie, I noticed the interactive space of some buttons was gone or at a different position or not the size I made it.

I made another button using the rectangle tool, and tested again. I noticed the visual button was at the place I put it, but the 'interactive space' was at the bottom right. Whenever I would move over this interactive space with my cursor, the visual button would instantly go to the place the interactive space is. Whenever I move the mouse out of the interactive space, the visual button goes back to its inital place.

Check it: (press start, 2 times the right arrow, then the window, then go to one of the buildings in the landscape and click on it)[URL].. Here you see two rectangle shape buttons. Hover over them, no interactivity. Move the mouse somewhat down to the right, and weirdness happens.

ActionScript 3.0 :: Image Gets Distorted When Scaled To A Smaller Size?

Jan 30, 2010

I made an SWF file (say X) and I have loaded this SWF file into another FLA file (say Y). With help from this forum, I got to do what I wanted - when I click on a button on the FLA file (Y), the SWF (X) shrinks to a smaller size (about half the size) and when I click on that same button again, X enlarges back to the original size. I acomplished this with tweenlite. THe SWF (X) has a slideshow of images. Now, when the SWF (X) shrinks to a smaller size, the images look very distorted and text in the images are not readable (although the text is large enough to be clearly visible).

They dont sound as good (muffled and distorted) when I publish the preview (flash or html). They sound fine within flash. When I switched the properties from "stream" to "event" it seemed to work great in the preview. I added a few more sounds and now only the first two mp3 clips sound clear and the rest now sound not so clear. They sound okay but I cant figure out why the rest sound bad? They now all have the exact same settings as the first two..

ActionScript 2.0 :: Distorted Objects - Modifying Width / Height

Oct 23, 2005

I have a problem where Flash takes it upon itself to modify the width/height x/y values I set objects (MC's) to, usually by less than a pixel. I don't get that.. and wouldn't that mess some things up like when I'm increasing the size of an mc someodd 300 times its original size, then that 0.2 pixel Flash adds in white space could become 50 pixels. Also, when I change the size of x MC, some other MC's will change their size. I can tell because the other MC's are about 1 pixel apart and when I change x MC that pixel is filled in sort of. I noticed some decrease in these problems when I was using whole numbers and x/y values, but it hasn't stopped it completely. I can give an example swf if necessary.
