How can I get the X, Y, and rotation values, relative to the stage of a child of unknown number of parents?
What I am doing is: I have a 'stick' object, that creates a child 'stick', that creates a child 'stick', etc a random number of times.
The end stick then creates a leaf.
Each new stick rotates a little bit randomly.
As a result when my leaf falls off the final stick it flies off in a strange direction.
How can I get the leaf to fall down (eg y++ relative to stage)?
Alternatively I thought I could dispatch an event that has a leaf created at the stage level but then I really need to know what the X and Y co-ordinates of my final stick is realtive to the stage.

How do you determine the "rotation point" (axis?) of an object?
A sprite/movieclip that has been loaded using a Loader has its rotation point set to the upper-left corner. What I want to know if how I manually (using ActionScript) set it to the center.
I'm writing a class for an instrment and one of the knobs has "snapping" values at X degrees.I have the code to make the knob snap to the set degrees,but I'm having trouble getting it to determine whether it was rotated clockwise or counter-clockwise.Here is the function that makes it rotate and "snap" The majority of the problem is because of the 0/360 and negative values that Flash has when it rotates..
In the function:
the _baseMovieClip is the clip that contains a graphic to rotate and "snap" to the degrees.
the _clipToRotate is a movie clip that actually displays the rotation
the _startAngle is the angle the user clicked on the button that triggers rotation
the _rotateObj is a sprite that is drawn when they click that I make visible to show the actual rotation when I'm debugging
the _snapLock is the degrees the knob shold rotate to (10, 15, 30, etc)

I'm using the following code in an app, but what I'd like to know is if there's a way to determine if a user mouses over the link. I would like to display a custom tooltip I've made when the user is mousing over a link, I've been looking for code that will accomplish this, i.e.: myText.addEventListener(TextEvent.MOUSE_OVER, doAFunction); - but I'm not able to find anything associated with mousing over a text link, aside from using a stylesheet. On the mousing over of a link, I want to determine if the event == httplink, a custom event I've created. If anyone could shed some light on how to accomplish this, I would be much obidged.

I have a clip of a small person 'flying', following the mouse coordinates. Its a 2d image facing a to one side. how I can determine when the mouse is moving right or left so that I can trigger the icon to 'flip' and face the other direction.
View 2 RepliesI'm trying to determine with the help of a mouse event if I'm over a specific component. So right now I have two components, let's say buttonA and buttonB. ButtonA has a listener on it already listening for the mouse out event. ButtonB is flush against the edge of ButtonA. I need to find out the code for it. Here is more details:

How would you calculate or determine the mouse speed on the stage? What i am trying to do is this:
You have a custom cursor which shows a plus sign when you very suddenly and fast change the direction of the mouse to the right. When you do the same to the left, the cursor changes to the minus sign.
However, if you steadily move the mouse from left to right while the mouse cursor is showing the minus sign, the mouse cursor stays the same, only on very fast change of direction the cursor changes?
i was wondering if theres a way to link the amount and direction of an objects rotation to the mouse position. I want it so if you move the mouse far to the left the object spins fast anticlockwise but if you move it to the center it stops.

I'm working on a Curling game and have a broom moving back and forth based on the mouseX position. Although I thought it would be as simple as recording the current broom position vs. the previous broom position that's not the case. This is because when you move back and forth the current and last postion may be at the very same point, like the center of the screen, depending on when exactly the mouse position is recorded. So, moving the mouse very slowly may give the same result and moving the mouse super fast where the x coordinate just happens to be recorded at or near the same point.
I tried using both an enterFrame event and a timer. Both yielded essentially the same results. I can't think of a way around this off the top of my head. Is there another way to record how fast the user is moving the mouse back and forth?
I'm trying to make a clip that will have another clip attached (eventually it'll be a mask) when you roll over it. I want the mouse positon to be determined on rollover and a different clip (with different registration point) to be attached depending on which quadrant you rollover first. IE- you rollover the lower left quadrant of the mc first so an mc with an upper right registration point is attached and follows the mouse.
Code:
leftfunction = function(){
if (patch._ymouse <= 100){

How do I rotate an object with the mouse after I have dragged the object with mouse.ssentially, I want to move the object with the mouse and then rotate it with another mouse click. Right now the object is moving and rotating at the sime time.
View 6 RepliesMy goal is to make it so that when the user clicks and drags the disc (whether it be click anywhere on the stage or clicking on the disc itself), the disk will turn according to where the mouse goes.
I've used this tutorial [URL] to make a simple arrow move when the mouse does to test the code and see if it works, and it does. But now i'm trying to figure out how to make it so it will only move when I drag the mouse. I've tried things like "onClipEvent (mouseDown)" and such but they don't drag the clip.
how to get the arrow/disc to drag (and eventually, play a sound, but I will worry about that later),

onClipEvent (mouseMove) {

I've got a very simple AS2 test file here:URL...I have a simple triangle, and it follows the mouse as it moves around.I'd like to get the triangle to change rotation, to follow the mouse, but my so far bodged version doesn't do that very elegantly.I have this AS on the MC that follows the mouse:[code]
View 3 RepliesI'm not really replacing the mouse cursor exactly. Just placing a custom image of a pointer below it so it will follow the mouse cursor as it moves around the screen. I want this pointer image to move with the mouse and to rotate and point in the direction the mouse is traveling. Simple stuff. The problem is that the rotation of the pointer graphic is not smooth at all. It is jumpy and somewhat erratic particularly at slower mouse speeds. When the mouse is moving quickly the problem seems to go away.
PHP Code:
package {
import flash.display.Sprite;
import flash.events.*;
public class MouseFollower extends Sprite {
private var pointer:Pointer = new Pointer(); // ...a simple triangle mc

I have a circle wheel i want to rotate and the speed should be based on the mouse position. I also need to have easing in and out.
When the user hovers over the bottom of the circle it will begin to rotate one way and then th top of the circle would make it rotate the other way. The further to the top or bottom they are the quick it spins. It ideally needs to ease in and out when it starts and stops when the user moves the mouse away.
The circle will be the complete movie so 50% top and bottom each for each direction.
The player rotates to the mouse when you click somewhere and moves there. The problem is sometimes when you click on a corner the player rotates towards where you clicked but sometimes starts moving sideways.
View 3 RepliesI'm trying to make a movieclip rotate around it's center (this is no problem since the center will never change). The problem that I am having is when I press the movieclip, in let's say the bottomright corner, and move the mouse the movieclip flips to a certain angle depending on my mouseposition. After the weird flip it works fine but it's the initial mouse click that makes the movieclip flip to an angle.I've tried playing around with different values to substract or add the starting angle but eveytime the result is not what i am looking for.Current code:

right now I have a code that rotates an object based on the position of it and the mouse. Thats all great but it sucks for a game, It is way too responsive. What I tried doing is making to rotation var:
[Code]...
after that I made rot2 the direct rotation between the object and the mouse: rot2 = Math.atan2(Ydiff, Xdiff) * 180/Math.PI; //(forgive me if this has spelling errors, as I am writing it //by hand right now) then I make rot effect the object: object.rotation = rot; now that the basics are set up I just need to make a code that compares rot2 and rot, if rot is less than rot2 it adds on to rot, if it is greater, then it will subtract.
(source at bottom) this all works well until you hit the most annoying part, the one i cant figure out how to fix.... basically there is a gap where the numbers go from 180 to -180, so the code flips out, reads this as it is supposed to, but this makes the object rotate a full 360 degrees around instead of just like 2 degrees to bridge the gap. If anyone has insight on this or thinks they might know what to do,

I am trying to create a effect using AS3. The effect is that several arms should rotate towards the mouse, and rotate less when their further away from the mouse cursor.using Math.atan2 to find how much the arm nedd to rotate to point against the mouse, and then substract the distance from the mouse.(look at the following picture) For example, if Math.atan2 returns 100 and the distance from the mouse is 40, the arm would rotate 60. Thats what i thought.But i cant get it to work. I attached the source files if you want to help Note:A blue ring in the source file indicates the distance.

But unfortunately, the ship does not follow mouse rotation. The ship only rotates with respect to the mouse when you move the ship, not when you move the mouse.
I have researched all over and have found some that "kind of" work, but the coding always has issues with CS3 (my version). I am more proficient in AS2, but would be willing to try AS3 if that is the way to go.I need a script that will allow the user to use their mouse to drag a wheel that will slow down to a stop. Think "Wheel of Fortune" style. Where it stops will trigger an event.
View 4 RepliesEssentially what I'm trying to do is nearly the same as this: http:[url].......However I'd like to ease/tween the movieclip position and rotation to the mouse position.The main issue I see is trying to get the current movieclip rotation and the target rotation,then tween it cockwise or counterclockwise from current to target.The way a movieclips rotation uses positive and negative numbers throws it off.If you just want to lock the mc rotation to the mouse rotation its fine, but once you try to tween it you run into difficulties. So the end effect would be like if you were to draw imaginary clockwise circles around the object, it should just keep rotating clockwise towards the mouse. Then if you started going counter clockwise it should just keep easing counter clockwise to the mouse.
View 1 RepliesFirst off, lemme start by saying that this site is incredibly awesome. Every time I have a problem or wish to learn something in Flash I turn to [URL]. Now for my problem. Have you ever played Madness? You know how, depending on where the mouse is, the hand rotates i.e. points at the mouse's current position? Well, I want to learn how to do that. I've attached a short animation demonstrating what I want to be able to do (the arrow points at the mouse's position, and then gun represents the movie clip that rotates) using a script
View 6 RepliesI have created a globe that rotates with no problem, but what I am trying to do is to control the direction of the rotation based on the mouse position. For example, if the mouse is to the right of the globe, it rotates towards the right and if the mouse in on the left, the globe rotates left. When the mouse is over the globe, it should stop.
