Actionscript 3.0 :: Motion Detection Rotation ?
May 14, 2009
What i need to do for my assignment is to get a Collada character head to detect movement through a web camera and rotate on its y axis.The Collada character will only turn when the movement is detected and when it gets to a certain point in its rotation then the game is over. When no movement is detected then the Collada character will have to turn back to its starting position.I want to make a min rotation variable of 0 and a max variable of 180 degrees.I have successfully added a basic collada image into my scene and it rotates on its y axis.
Code: Select allpackage{
import flash.display.Sprite;
import flash.display.DisplayObject;[code]....

I am using Corey Oneil's collision detection kit, but I am having a problem with rotation. In my code I have:
myItem.rotationY = 180;
However, during a collision detection, having it rotated like this causes an error with this line:
transMatrix1.concat(currentObj.parent.transform.ma trix);
The error is simply "Error #1009: Cannot access a property or method of a null object reference."
I have not really worked with matrices and rotation. Do I need to make a matrix rather than just doing the rotationY or should I change something else? I cannot manually change the movie clip because it throws off the animation and armatures.

I'm currently trying to use flash8 and my webcam to do something similar to [URL] I've just started playing with camera scripts and therefore am stuck with quite alot of problems. But i decided to go on step by step. First problem i met, I am unable to display the snapshot of my webcam into a movieclip.. As in i want to take a frame of my webcam input and draw it into a movieclip.. (so i can compare with later frames to see if there is any motion.) Anyone can help me out here? What is wrong with my script? It's just supposed to take the webcam image on every enterframe and input it to my movieclip right beside my live input of my webcam.. But it appears as a blank MC..

I'm trying to access the rotationY property in code to determine the current state of a movie clip that has its rotationY animated in the motion editor. What I'm seeing is that the value of the property reported in a trace stmt is different than the value shown in the motion editor.
In the motion editor I created a tween from rotationY=0 at frame 0 to rotationY=353 at the last frame. I've added the attached code to get the value of rotationY at every frame.
What I see is that the rotation does not increase steadily from 0 to 353. Instead it increases from 0 to 90 and then decreases back to 0 and then goes negative to -90 at which point the absolute values decrease toward 0. This seems like a bug. The rotation of the object is visibly different during the 0 to 90 deg

I recently installed Flash CS4. As I attempt to learn from different tutorials I've run into a problem I can't figure out. I've watched the video tutorial at: [URL] several times to try to emulate the rotating logo. The problem I run into is when he says to open the Motion Editor and to edit the Rotation Y and Rotation Z properties. When I open my Motion Editor there is no Rotation Y or Rotation X. There is only a Rotation Z property. I've played it over and over to try to discover what setting I've missed but don't see it. How do I see a Rotation Y property to be able to edit it?

Is there a way to prevent a motion tween w/ rotation from dropping on the Y axis? Basically I used Free Transform to change the angle of a line, but it always lowers itself on the Y axis when I insert a motion tween in it.

I'm using flash CS4 and I'm trying to create a motion tween with a rotation (several actually) and every once and a while Flash decides to screw up my tween and I don't know how to fix it. So i have an arm(symbol) with the rotation point set at the elbow... after I've already moved it and rotated it a few times without an issue, I try to rotate it about 20 degrees and all of the sudden my arm is randomly doing a 360 degree spin. I can't seem to fix this!

I have a circle: Width 530 and height 800. I want an object to follow this circle using a motion path, but you cant do that in pure actionscript, so I tried rotating the circle with the object attached, but warping the circle at the same time... so width becomes 530 and height becomes 800... but because the circle has rotated at the same time, it looks like it hasn't moved - except for the object attached.
ActionScript Code:
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var Tween1:Tween = new Tween(circle,"width",None.easeNone,800,530,2,true);
var Tween2:Tween = new Tween(circle,"height",None.easeNone,530,800,2,true);
var myTween:Tween = new Tween(circle,"rotation",None.easeNone,0,180,2,true);
This was the closest... but it still dances around the page before anything happens.... and it isn't reading the sizes properly? 530 isn't 530, but something bigger, and 800 is actually smaller?

I want to apply a motion blur to the rotation of a movie clip. I am currently rotating the movie clip 540 degrees via actionscript using the tween class below:
Code:
import mx.transitions.Tween;
import mx.transitions.easing.*;
var targetRotate:Tween = new Tween(_root.target_mc, "_rotation", Regular.easeInOut, 0, 540, 3, true);
[Code] .....
This seems to be a good start, but I need to change it to apply to the _rotation of my movie clip. Lets say for the sake of argument, my movie clip has an instance name of target_mc as well.

I'm just now trying the Motion Editor for the first time in CS4 Professional. I've created a shape, converted it to a symbol, done an Insert Motion Tween, and brought up the Motion Editor. I'm looking for Rotation X and Rotation Y, but only see Rotation Z. My Publish Settings are Flash Player 10, ActionScript 3.

I have a rotation value in degrees(0-360) and a value for magnitude, ie (1-10 pixels per second).
How to apply this information to determine what to add to an objects x and y values to send the object off in a given direction at a given speed ?

I'm trying to do some augmented reality projects with flartoolkit . I can now put simple 3d objects on my marker and it works fine , but I wanna give my project some events that the user can interact with. I'm trying to trace the rotation of the marker. there's a container:DisplayObject3D which my application uses to add the 3d objects , I traced this :"trace(container.rotationZ)" but it's just returning 0 . I studied another AR application's source code and it was using the rotation of it's container object without problem .and I think I should mention that I'm using the exercise file of seb lee delisle papervision3d course from [URL]. anyone has any experience with flartoolkit? the main functions of my my code is as below:

Is it possible to have the child movieclip rotate separate of the rotation properties assigned to the parent? so ultimately giving the child element it's own axis?I've customized Lee Brimelows (gotoandlearn.com) 3D carousel to spin on the x axis to make it a vertical carousel. I've also rotated that by 45 degrees on the y axis to see all the items, and wrote a snippet of code to hide the left portion of the carousel. The entire carousel is contained within the 'container' movieclip, and inside of that are my carousel items (as seen below), with the larger item being the item in focus.
On rollover of the item in focus, I want to rotate it so it faces the viewer (as seen below),basically removing the 45 degree rotation applied to the container.The problem i'm running into is when you rotate the container (changing the rotationX of the container), the axis basically rotates with it, so when i rollover the next item 'in focus', the following happens..(in the example where it appears how it want it to, the carousel is at a rotationX of 0, so it works fine)

Program A has a cannon that aims to line up with where-ever the mouse is pointing, in 360 degrees, and fires when the mouse is is clicked. Program B has an eye instead of a cannon that should in theory do similar functions when the capslock key is toggled, but instead only has a 90 degree range of motion from the Right of the eye toward the bottom (quadrant 4 only). Where did the ther 270 degrees of rotation disappear to?

i.m trying to create a 3d rotation much like the widely used carousel only the rotation i desire consist of four upright(90 degrees) movieclips resting on a slanted, 30 degree plane which rotate onEnterFrame or following a tween on a oval like path - then pause for a given number of seconds at the four movieclips positions equal in distance on the plane
function around() {
this._x = Math.cos(this.angle) * radiusX + centerX;
this._y = Math.sin(this.angle) * radiusY + centerY;
var s = this._y /(centerY+radiusY);

I have been searching far and wide for a solution on how to offer slow motion and fast motion options for users that upload video to my webstie. There is an implementation on Google Video that has exactly what I am looking for: the option to speed up or slow down the video and continue to play the audio. The screenshot is below. I know that Flowplayer has an option to slow down or speed up video when implemented with Wowza server. However, when using that approach, there is no sound.
I have also seen the option from Enounce called MySpeed that allows video to be slowed or quickened, but this requires a browser plugin which is too much of a barrier for our users. How does Google do it? How can you add an option to a flash player to slow down or speed up video?Here is a screen shot. You can see the option to change the speed of the video to 1.5x. It also has options to go to 0.5x, 1.25x, 1.5x, 1.75x, 2.0x, 2.5x, and 3.0x.

I would like to create a polygon that changes its shape (circle, trapezium, square, rectangle, triangle) based on specific buttons that the user clicks? An existing shape has to be able to morph into all the others. For instance, the trapezium has to morph to a square, circle, rectangle or triangle.
If I were to create each transition manually, I would end up with 5x4=20 scenes. Is there a way that I can just assign each shape to its own frame, and deploy actionscript to set in motion the transitions from one frame to the 4 other possible frames? I am very grateful to anyone to just point me in the right direction,

I am trying to do a simple "pseudo 3D" rotation of a movie clip. The clip would "flip" on to the screen. I have created the effect using PaperVision3D, however, the final SWF is about 64k and my project requires a smaller file size. I tried to create the flip effect manually by creating skewed versions of the clip and tweening between them, except this doesn't work because the shape is not tweaked along the vanishing point as it should be. It looks like perhaps I could accomplish what I want to do using the MatrixTransformer but I've not had much luck so far.

im writing AS3 under linux and as such do not have access to ANY of the fl.* packages, including tweens, motions, special animations and components. I can only use Math.* and XY Grid Coordinates to calculate motion manually.
I can make movement of sprites fairly easily on a coordinate system, but this restricts how the path can go. Usualy only an up,down,left,right movements for the simplest math. I suppose this could be expanded to move in more varied directions but its not quite what im looking for.
I would like to be able to draw an invisible line that a shape can follow. Then it can have curves or bends in it without problem. I want to then start the sprite at the 1st pixel of the line and set its next coorinate based on where the line is at, but at 10px down it (and so on) till it reaches the end of the line. Is it possible because I cant think of a way? Are there any other good PureAs3 motion tutorials around?
