ActionScript 3.0 :: Inverse Kinematics(IK) And Mouse Interaction/position?
Jan 2, 2011
For a site im working on I want an object to move thats hanging on a piece of wire made with the bone tool to move when my mouse is moved towards it so it would swing when the mouse is placed near.I thought using a simple code to move the movieclip attached to the bone would work but it just moves the movie clip and forgets about the kinematics. this is the code i used:
ActionScript Code:
stage.addEventListener(Event.ENTER_FRAME,followmouse);
function followmouse(event:Event):void {
var dx:int = box.x - mouseX;
[code]....

I was reading about the "bones" tool in Flash CS4, and the IK library that comes with it, but I don't have access to CS4...so I'm wondering if there is a smilar tool and library for CS3 users, who may want to create these effects with Actionscript.

I am trying to find where the IKManager is located on my file system, so that I can import it into my project from Flex Builder. Though this class apparently comes standard with CS4, it's nowhere to be found on the filesystem. Can anyone point me in the right direction? Is it in a swc file?

I am looking for leads on an Open Source IK library for AS3.
My project involves simple 2D limbs with shoulder/elbow/wrist joints.
If I am unable to find anything I am going to try and write one, although my math is not anywhere near up to the task.

I have a var that captures a slider position like this:
Code:
var sliderPosition = Math.round((thumb.y-bounds.top)/(bounds.right-bounds.top)*100);
which outputs a number between 0 and 100 starting on 0. I need to scale an mc from 1 at sliderPosition =0 to .42 at sliderPosition = 100.

im using the code below to draw a circle.
How can i modify it so that it draws a circle when the mouse is still. In other words, it draws when teres no mouse interaction, clicks, movments.
ActionScript Code:
_drawboard.addEventListener(MouseEvent.RIGHT_CLICK, _handleMouseEvent);
_drawboard.addEventListener(MouseEvent.MOUSE_UP, _handleMouseEvent);
[Code].....

I would like a 'MouseOver' event to trigger a timer. then once the designated time is up the code will instruct to 'GotoAndPlay' the 2nd part of the MC. (so the MC will play from a designated frame - no probs there.) I know almost nothing about timer events and believe this is probably extremely easy to do; it's just that I don't know the code required.
I also know that a simple, but long way round, way of doing it would be to simply add a set of 'still' frames amounting to a certain amount of time. I am very curious about using timers though.

im making my portfolio in flash. And the designing goes oke etc, but now im at the programming part, and thats not what im good at.[URL] If you mouse your cursor over the most right (black) button you see "contact" fading in, thats oke, and when you click on it a big orange shape slides in, some text is needed to put in here. But! When you move the mouse of the button the orange shape slides back.
So my question is, how can I make the orange shape stay while the mouse is of the button? And when the mouse moves out of the contact button and over another it should fade in that name to, (like it does now).

Basically the x position of the mouse should control the play position of a movie. Do I need something like an event handler (I'm not sure exactly what these do, but I've seen similar scripts that seem to use them).

I have an Input Text area that users can edit and then submit. I need to be able to show, on screen, the cursor's current position as they type. I don't need to know where the mouse is but all work-arounds I've found so far can only tell me the mouse position. The font for the text is 'courier' or 'courier new' and the Input Text area is scrollable.

I have a map application that when I use the mouse wheel the map will scale up or scale down. The next thing I want to do is to focus on the mouse pointer while zooming on the part of the map.
I have this code...
function focusMousePosition(){ onMouseMove = function (){ Stage.width = _root._xmouse; Stage.height = _root._ymouse; updateAfterEvent(); }}
var mouseWheelListener = new Object();var wheelNum:Number;
mouseWheelListener.onMouseWheel = function(wheelNum){ focusMousePosition(); if (wheelNum > 0){ map._xscale *= 0.9; map._yscale *= 0.9; }else{ map._xscale *= 1.1; map._yscale *= 1.1; }}Mouse.addListener(mouseWheelListener);

Code:
addEventListener(MouseEvent.MOUSE_WHEEL,mouseWheel);
function mouseWheel(event:MouseEvent) {
Map.scaleX = Map.scaleX + event.delta*.01;
Map.scaleY = Map.scaleX;
}
The problem with this code is that it scales from the registration point (0,0). Due to the other transformations I'm doing to this image at various times, it isn't possible to move the registration point. The image is larger than the stage and the user is able to drag it around. I want the mouse wheel to zoom in on the place the mouse is hovering over (or at a minimum...the center of the "view" they have...aka the stage)I tried doing this:
Code:
internalPoint = new Point(Map.mouseX, Map.mouseY);
externalPoint = new Point(stage.mouseX, stage.mouseY);
var matrix:Matrix = Map.transform.matrix;
[code]....
Which, incidentally, I'm using that whole portion of code to zoom into the state they will be in when they use the mouse wheel.

say i have 9 children in a xml code.when i read it into AS3 i get 0~8 children.what if i wanted an inversion of this?
ie
xml[0] = xml[8]
1 = 7
2 = 6
etc
so then i could have two versions, xmlA as the regular 0~8, and xmlB is inverted.

I've taken this problem far and wide, and it's a common one, too: Someone wants to use a mask inversely, hiding the masked object instead of revealing it. The only coded solution is to create a bigger "stage" mask with the inverse mask cut out. I understand the process, and have a slight grip on methods of executing it. Too bad it still will not work properly. I have employed two solutions to no avail. There was this simple option, and then there was this slightly harder option.
And where it works for some people, it is not working in my instance. If you look at my files, the masks cut out rather strangely. Is there something different about this situation that requires a different line of code, or am I simply using it wrong? To show you how they worked out, this is the goal: And this is what I ended up with after option 2: Because the object will be squishing and changing shape, creating the mask frame by frame would be a hassle. Changing the shape of a solid mask is a lot easier than moving the particular points of a "stage" mask manually.

I am trying to get the mouse's position even when it is outside of the flash window. How can I do this?stage.mouseX/Y only returns the mouse position on the stage, not when the mouse is outside. Is there another way?

If you click the scroller in this .fla I've attached the text jumps away at first. The jump increases when you increase the [x]*dydrag function in value. I want the text to follow the inverse motion of the scroller very smoothly.

The closest I have come to is the basic mouse hide and then mouse show, however this only gives the illusion of the cursor not being there, however you can still use it. I would like the cursor to be 'disabled' within the flash movie for a limited time. Either by it disapearing and then reappearing, or by it being frozen in place

I have a panning background with buttons in it. It would be nice if when the button is pressed i could move the position of the mouse so that the movie pans and catches up with the new position. Is this possible?

I want to do something which is probably pretty simple but I've got absolutely no idea how to do it!What I want is for the Alpha value of an object (movie clip) to change depending on the x position of the mouse. So when the mouse is at 0 the alpha of the object will be 0%, and when it's at 100 the alpha will be 100%

So I'm working on my portfolio and I got this problem. The code posted scrolls the sprite "cellContainer" based on the position of stage.mouseY. Perfect.Problem is that I want stage.mouseY to equal the entire cellContainer height. Kind of like how a small tablet equals a huge monitor. So when stage.mouseY = 0,cellContainer.y = 0 and when stage.mouseY = stage.stageHeight, cellContainer.y = stage.stageHeight - cellContainer.height. Right now, it scrolls, but it takes a while to scroll throught the entire height of cellContainer. I want it to be proportional to stage.mouseY.
Actionscript Code:
private function scrollStart(e:Event)[code]....
