Actionscript 3 :: Continuous Value From Rotation Slider?
Oct 28, 2011
I have a dial which I drag around a circle to give me a reading between 0 and 1.
Something like this:
dx = mouseX-centerX;
dy = mouseY-centerY;
rad = Math.atan2(dy,dx);
[Code]......
This work's great, except when the slider goes from 359 degrees to 1 degree, my value between 0 and 1 returns to zero. (Which makes sense, as the value is based on the angle of my slider)
I'm trying to find a way for the dial to move from 359 degrees to 361 and onwards basically.
In my head: I need to check if the next value of my mouse drag goes past the 360 degree point and add 360 to the total, to stop it returning to zero and continue to 361 degrees.

I have a nested MC that functions as a continuous slider; when you mouse right of center it slides one way and when you mouse left of center it slides the opposite direction. Right at center it stops. The problem I have is that I'm using this as a menu at the bottom of a .swf and there are other places to mouse on the page, which means that this menu is constantly in motion even when it's not being used. I want it to stop when it isn't being used, only because it's an MC I can't use the onMouseOut command to stop the clip. I tried making a button that targets the clip and stops it when you roll over the button but it doesn't work.
Here's the script I'm currently using:
onClipEvent (mouseMove) {
xcenter = 467.5;
speed = 1/25;
} onClipEvent (enterFrame) {
var distance = _root._xmouse-xcenter;

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);

What I have is a map that you can click on points and it will zoom in, you can also click on a "plus/minus" buttons to zoom in and out (I even have the mouse wheel zooming in and out). The client wanted me to add a "zoom slider bar" to it so you know you could move it up and down to scale it. Everything is working except the slider, I can't seem to get it to work with the position of the slider. All of the zoom functionality is there but the slider is killing me.
I am putting up the fla file since there is a lot of code in there and I didn't want to put it all in the forum. if you look in the fla in frame ten on line 726 you can find the function that is supposed to handle the zooming when you move the slider. Up on line 74 you can find the slider onPress and onRelease functions, but those I believe should be fine.

I am trying to create a basic timeline, similar to the timeline we all use in flash (see attached).
I have a playhead slider, which when dragged, just drags within its startDrag() limits.
I also have horizontal window scroller which also when dragged, just drags within its startDrag() limits.
I am trying to work out how to get the horizontal window scroller to scroll when the playhead slider hits the left or right edge. I am using hittest for this collision.
I have the playHeadSlider scrolling along the top. When playHeadSlider collides with hittestThing I want mcContents to then move.
It kind of works.. mcContents moves when the playHeadSlider is in collision with the hittestThing.. but it just moves rather than 'drags' across. I have it set up so that mcContents is twice the width (approx) of mcScrollWindow.
I need to somehow update what I have so that if the playHeadSlider collides with hittestThing on the right, mcContents only moves to the right and if playHeadSlider collides with hittestThing2 on the left, mcContents only moves to the left.

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.

i'm trying to achieve an effect in which a triangle movieclip (which expands and then dissolves) respawns itself continuously. I'm hoping to figure out how to tell flash to respawn a new instance of the 15-frame movieclip of the triangle, when the original clip hits frame 5. the next one would do the same, and so on and so forth.My research so far has led me to believe this has something to do with the 'addChild' function but i'm so far unsure of what to do with it

I have about 27 photos. They are all 250x188. I would like the work space to be 250x564 so that 3 photos display first and they keep scrolling from the bottom to the top continuously through all the photos and repeat. Could someone recommend the best way to do this in Flash CS4. I am totally new to this.

I currently have an animaion I'm creating in Flash CS4. There are 3 nested movieclips on the main timeline (all on one layer) each in there own frame (1,2,3) and they are also labelled ("strategy", "videos", and "messages") I want the animation to play continously without any interaction from the user i.e clicking buttons e.t.c I'm struggling to link the three movieclips together using ACS3 i.e once MovieClip one has played it will go back to the main timeline and play the second MovieClip on frame 2 and so on. From looking at various forums I thought the gotoAndPlay function may work, would I also need to specify that it is going back to the "root" timeline?

I have a horizontal image scroll that is made up of various thumbnails. When you move your mouse to the left it goes left, move it to the right and it goes right.The problem here lies somewhere in making the loop continuous. I have it looping correctly. There are masks on each thumbnail.
I have two instances of the same movieclip that contains the thumbnails right next to each other. This allows it to loop.When two instances of the thumbnails are both on the screen at the same time, a few of them lose their masks while they are on the stage. Why is this?

Hudson

Both seem to be popular on the general level but have you got some direct experience with using one or both with Flex development? Or would you recommend some other tool?

I want to make a scrollbar of a dynamic text continuous when clicking up or down ie when holding the mouse down the text should scroll and when MOUSE_UP the text should stop scrolling. I tried making it with ENTER_FRAME Event but it happens too fast(when i click once the text scrols by 3-4 lines).
I would like to apply the hold effect, like when you press down in your browser window for example: the page first holds for a second and then start to scroll. I hope you get the idea. How to acomplish this in AS3?
