ActionScript 2.0 :: Constrain Dragging To A Circular Path?
Oct 4, 2004
I am designing an interface where a person will drag a circular measurement tool (called a goniometer) over part of an image, and then rotate two different arms on the tool to measure an angle.The entire tool itself needs to be draggable by its center. So far I have the arms rotating by means of pressing the arrow keys on the keyboard, but it would be more realistic to have the user drag the arms to rotate them. I can't think of how to accomplish that, though.

What I would like to have happen, is when the user drags arrow_mc, it will only rotate between 0 and 90 degrees. If you go above 90 degrees, and continue dragging, it will stop moving. The same would happen if you went below 0 degrees.Currently, the code below works, but you can go around in circles back and forth.Iwith figuring out how to constrain the drag rotation between specifid numbers, in degrees.
ActionScript Code:
arrow_mc.onPress = function () {
arrow_mc.onMouseMove = function () {

I'm trying to make a circular motion path using Senocular's tutorial here.What I want is a box to move around a circle motion path that is created in AS when the user presses a button. However I'm having trouble decifering all of Sencular's code because there is a lot of advanced stuff that he puts in that I don't want and I'm having trouble getting started.

I am trying to place leaves in a circle to create a flower with code. I run into some problems.Is it possible to rotate the leaves so they all rotate in the direction of the center of the flower? And is it possible to calculate how many leaves can fit around a certain circle radius without to much overlapping?

I can't seem to figure out how to accomplish a fairly simple task: I have a simple graphic and I'd like to apply an "orbiting" effect to it - so that the graphic moves in a circle around an arbitrary point (without rotating around its own center).[code]...

I'm attempting to create a color wheel component in Flex 4 that will allow me to represent RGB and HSL data.I'm doing so with a circular color wheel representing the various hues available to me and a rectangular gradient in the center of that which will represent the lightness and saturation fields
Currently I have the objects represented but I cannot determine the best way to fill them in. I have no problem creating the gradient necessary in the center square, but I cannot get the outer ring to build a -circular- gradient. It seems the only two native gradients in flex are linear and radial, but I need the gradient to linearly follow the path around the ellipse. How would I make this possible?
Here's the attempt I've made thus far:
<s:Group>
<s:Ellipse x="7" y="7" width="136" height="136">
<s:stroke>
<s:LinearGradientStroke weight="14">

I am new to action script (using AS2). I have a symbol (a button that looks like an arrowhead). I've used the code below to drag the arrowhead around the stage (where "arrow" is the symbol's instance on the stage)
But, I want the "arrowhead" to only be able to be dragged along a particular path -- picture a curved line that looks like a smile. SO, the user can only drag the symbol along that curved path.

I have a movie, within this movie I have a container which loads an external swf, the problem I have is that when this movie is viewed within a browser, if the browser is resized then the external swf that loads into the contanier resizes, going smaller or larger.How do I constrain a particular container to stay the same size, 100%?This is the script I have that loads the external swf, is there a way to constrain container?

I'm loading a .swf (flash game) (719 x 480) into a new .fla that is bigger (1280, 720) than the dimensions of the .swfThe game appears to load well, but when I start playing it, I realize that the game is messed up because it is actually running in the dimensions of the .flaCan somebody tell me how to constrain the loaded .swf to 719 x 480?NOTE: I can't change the .swf game file's codingAnd the .fla stage-size has to stay the same.

I load swf files continuously, but if one of the swfs has some defective code such as Mouse.hide() the mouse disappears when the swf is loaded. I want to constrain such malicious code in loaded swfs. There is also another problem related to containing loaded or loading swfs. When I load a swf which loads another swf to operate, It never completes loading (Event.Complete of contentLoaderInfo) because it needs another swf to load. However, the swf should be loaded before it runs. Since loaded swf is as-2, loader does not give any error. I am also suspicious whether or not it will give error if it is as-3.

I'm at a bit of a coders block, and I'm sure it's quite simple. I tried using the following:Code:((angle-180)%360) + 180But for angles < 180 degrees, it works just fine, but after that it get's a little funny. I know why it's doing that, I'm just looking for a way to fix it.

I have a MC called planPOPUP which is draggable and at the moment I am constraining where the MC can be dragged to by using the 4 co-ordinates method such as:
Code:
startDrag (_root.loadHERE.allImagesMC.planPOPUP, false, 116, 231, 913, 396);
Now would it be possible to, instead of using that method, place another MC around the edge of the stage, making a border, and then have some code so that whenever planPOPUP touches the border MC it cannot be dragged over it? Thus constraining it to within the borders of the stage?

[code]...Now if I load this swf into a bigger SWF the mouse is acting in the entire movie as if it were in de loaded swf. This also happens when I test it (ctrl-enter) and make the resulting box bigger... the mouse will not fade at the border of the swf any more, but at the border of the containing window....) is there a (easy) way to constrain the mouse behaviour within the box of the loaded swf (like the MOUSELEAVE event triggered when i leave the box of the loaded swf in stead of the entire stage?)

I have some script that loads an external image into the UILoader that also has a mask created based on loaded image width and height, which also centers on stage. That works great. On user click somewhere within the loaded image, the image then scales from that mouse position out.
i.e.: if I click top left corner image scales from that point out, center, left, right... etc. using the tween. That works great.
On mouse move image then pans reverse to mouse position. i.e.: I move mouse left image pans right, move mouse up image pans down, top left corner image pans down bot right...etc. Also using tween. This is where it becomes tricky. The image does pan, however it does not pan completely to left, right, up, down, diagonally and so forth. once mouse reaches boarder of mask the image pan stops, unless mouse is way outside boarder.
Then that creates another problem where the image now pans so much that it goes past the boarder and almost out of sight. Ideally when mouse moves to masked boarder, panned image should be at its image boarder then stop. Constrained within the masked boarders.
Code:
var myImagePanTween;
function moveImageTween(e:TweenEvent = null):void {
var CurrentMouseX=mouseX;
var CurrentMouseY=mouseY;
[Code] .....
I think there should be away to include a constraint within the Tween, as well calculate the image size so that when mouse reaches boarder the image should be panned to its width/height, up, down, corners ect.. within the mask. Make sense?

the same class is passed to the mxmlc compiler in SWF library as a symbol linkage class and again in a source-path. But the compiler uses the definition from the source-path so creating new instance of that class won't create new instance of the library symbol. How do I tell the compiler to prefer the definition linked to the symbol (the one dfrom SWC)?
I have my design assets in an FLA file and they are linked to classes (e.g. [URL]. Then I export those assets to a SWC library and pass it to the compiler. Now when I create an instance of the class (new MyAsset();) it will be a new instance of the library object.
But there are other classes too in the source folder (e.g. "com.myproject.model.*" so I need to pass the source folder to the compiler too. And that is the problem, now the compiler will use the MyAsset.as definition from the source path, not from the SWC where it is assigned to the library object so if I create new instance of MyAsset now it won't duplicate the library object.

I have a draggable slider that looks like this:
The blue bar has the instance name track and the pink dot has the instance name puck.
I need the puck to be constrained within the blue area at all times, and this is where my maths failings work against me! So far I have the puck moving along the x axis only like this:
private function init():void
{
zeroPoint = track.x + (track.width/2);
puck.x = zeroPoint-(puck.width/2);
