ActionScript 3.0 :: Flash Dragging A Map Image
Feb 18, 2011
I have been working on this project. I am pretty new to flash but developing a map application with pan and zoom. I decided to improve it slightly by adding in mouse functionality. I have the mouse wheel controlling zoom, and I understand the object.startdrag and stopstopdrag and how to make it work. How ever it moves the entire object, which meeses up the built in buttons that pan around the map.I am wondering if any of the flash gurus on this site would venture a guess for a solution to making mouse down add a pan function similar to the way button clicks work.[code]

Everytime I'm trying to drag an image from the library to the stage, the program crashes. I've been sending the crash logs to Adobe many times, but never got any solution from them.
In the log there a line that says:
<crash exception="EXCEPTION_ACCESS_VIOLATION" instruction="0x0c4feb66>
I'm working with 10.0.2, I thought the latest update will fix that, but it doesn't. Changing the UI from Essential to Classic doesn't help

I am having trouble in dragging a image within a loader. I am able to do zooming and rotating image but not moving image with mouse. Purpose is when I zoom a image info is out of boundaries and so is hidden. To see that info users should be able to drag the image any way they want.

I am really interested in the separate images loading and connecting at the xpoint. And of course the tween dragging of the overall sections. I have a terrible example I have begun working on, but it works on the _root._ymouse and _root._xmouse positions. The images also overlapp. Here is the link to the example site. [URL].

I have a project with a deadline.I have a panel of images that scroll with mouse_over. When I drag an image over the panel and get to the other side of the panel - basically hitting the image against the border of the panel, the panel stops scrolling.I can resolve this?Here is the code:
private function panelOver(e:MouseEvent):void
{
sPanel.useHandCursor = true;

how can I drag a specific image without dragging all the other objects. The image to be dragged is exported dynamically from the library and activated on a mouse over. Here is the code:
function myImage(event:MouseEvent):void {
var img:BitmapData=new livery(0,0);
var MyImg:Bitmap=new Bitmap(img);

How can I constrain an image in a container to only a horizontal drag that when it collides with another image 'pushes' that image along that same horizontal line.

I wanted to create effect in AS3 like initially image is still and when I pull image then that image should drag and hang. And, when I again start dragging that particular image then its registration point should change and image should hang on new registration point.

My application (AS3) uses Flash Player right-click zoom feature. However, when zoomed in I cannot drag when the cursor is over an image, navigation bar or active area.This makes the menu and several other pages impossible to navigate when zoomed in.The only option is for the user to zoom out and then zoom back in on the next area they want to look at.how default dragging can be enabled when cursor is over an image/ moviclip?

I have a script that loads an external image into the stage(I have the addChild() script somewhere else) but I keep getting an error that says:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::Loader@b1b7101 to flash.display.MovieClip.
at project1_fla::MainTimeline/drag()
[Code]....
What I do to make the image draggable? *(The image is loaded when the swf starts but the image won't because I put the addChild() in a if() statement. Could it be that since the image isn't loaded, it can't be a movieclip?)

I have run into a drag and drop issue .I have an item that I would like to drag and drop. Seems simple enough, but I also want to make it that if the user drags the image off the screen, that it stops dragging and returns the image to the center of the screen. What happens now is that it continues dragging and sticks to the cursor if you release outside of the viewable area. The original piece has a lot of other things going on, so I ve created a simple piece with the AS in the timeline that shows only this particular issue.
Code:
var mrT:MC_mrT = new MC_mrT;
addChild(mrT);
mrT.x = stage.stageWidth*.5;[code].............

I have a flash project with three non overlapping panels (visual spaces) each of which contains different movie-clips. Each movie-clip in a particular panel is the child of that panel.Now, I want to drag one of the movie-clips from one panel to another (remove it as a child from the first panel and add it to the other) without a jitter and proper drag.What is the appropriate way to handle the drag architecturally

So I've noticed Windows 7 has a disturbing tendency to prevent you from dragging the title bar of windows off the top of the screen. If you try - in this case, using an air app with a draggable area at the bottom of the window, allowing you to push the top of the window up past the screen - it just kicks the window back down far enough that the title bar is at the top of what it considers the 'visible area.'
One solution would be to resize the app window as it moves, so that the title bar is always where windows wants it. How would you resize the window while you're dragging it, though? Would you do it like this?
dragHitArea.addEventListener(MouseEvent.MOUSE_DOWN, function(e:MouseEvent):void{
stage.nativeWindow.height += 50;
stage.nativeWindow.startMove();
stage.nativeWindow.height -= 50;
});
see what's going on there? When I click, I'm doing startMove(), which is hooking into the OS' function for dragging a window around. I'm also increasing and decreasing the height of the window by 50 pixels - which should give me no net increase, right?
Wrong - the first '.height +=' gets executed, but the '.height -=' after the .startMove() never runs.

I know I'm using an older version of Flash (still using Professional 8) but I'm wondering if it's possible to have items be able to be more interactive in that the user can select an item with their mouse and drag it over another item and drop it on there.

I have a simple AS class:
package Bubbles
{
import flash.display.Sprite;
import flash.events.MouseEvent;
[Code]....
Stage only has that green rectangle on it. If I remove it nothing changes. If I change line thickness to 6 trails does not appear, at 7 and higher they appear. You can check SWF here: [URL]. How do I make it work correctly?
Update: If I change that rectangle shape to something star-like with sharp angles, trails appear even on lower thickness values (trails appear when thickness == 3 or more).

I have a project with Flash Professional CS5 and ActionScript 3.
I need to trigger an event when I drag an object over a particular spot, but haven't dropped it yet. Then, I need to trigger a different event when I leave that spot (still dragging). However, this should only occur while I am dragging on object.
The traditional mouse over and mouse leave events aren't working while dragging (only while not dragging).

I am doing some pre-production on a project that requires drawing on a 3d canvas, which I think flash is the best way to go. But there is a chance down the line that this client might want the site to show up on the ipad, iphone or other mobile devices that don't support flash.
So I was playing with the idea of doing everything in html and javascript except for the actual drawing/3D area. Almost like using flash as the element. I think html5 is too premature to start using this, but might be beneficial down the line. Chances are I will just go the entire flash route, but I thought it would be interesting to try. question is pretty top level. 1) how hard would it be to drag an object from an html page using javascript, and dropping it into the flashplayer. And then manipulating it from there.
Are there any examples out there that have tried to do this?

I thought I had a really simple task to do: Create an analog clock where student could set the time by moving the hours and minutes handles.Well, the whole thing works to a point... I have created a bone system to ensure that both handles bases stay put in the center of the clock while the handles get dragged about. The problem is that I cannot restrict the user movement within the "reach" of each handle (or is there?) and if the mouse happens to be OUTSIDE of the dragged handle at drop point, the MOUSE_UP event does not trigger.I have also looked for a MovieClipModified event which would work wonders in this case but I could not find it...

I have a draggable item, a MovieClip that calls startDrag() on itself when it is clicked, and another MovieClip on the stage.I need the MovieClip to receive ROLL_OVER and ROLL_OUT events while the draggable MovieClip is being dragged over it, but the lower clip doesn't receive these messages while a clip is being dragged over it.Essentially, ROLL_OVER is only sent to the topmost MovieClip under the mouse. Normally, you'd fix that with some combination of mouseEnabled or mouseChildren on the overlapping MovieClips, but if you do that to a draggable MovieClip, it breaks dragging. I need to detect when the mouse is over the lower MovieClip, regardless of what MovieClips are above it.

I have a canvas onto which I draw shapes like rectangle etc. When I move the shape using my custom mouse down/mouse move handler, the shape can go outside the parent bounds.
I am checking if the child is outside the parent's bound to snap it back:
var bounds:Rectangle = this.getBounds(this.parent);
var p:Point;
if (bounds.x <0) {
[Code]...
The snapInside method gets called when I go outside the left or top boundary. But when the child is dragged outside the right or bottom boundary, I find Flex/Flash runtime automatically expands the parent's height and width. So say the parent size was initially 800x600, if child Y bounds exceed 800 by say 20 pixel, I find the this.parent.height automatically resized by flex to 820!!
How do I prevent the parent from resizing when child goes outside the original bounds of the parent ?

EDIT: If I have a class called Items and it has a movieclip instance which is loaded from a url. The startDrag on item fails. If Items contains a movieclip which we initiate from a SWC (not load it) on Drag works fine. Now how to solve the issue where I have a class which has a movieClip loaded from outside.I have the following code:
package {

is it possible for flash to detect off-stage mouse coordinates in order to continuously drag an object within its bounds while the mouse is moving outside of the stage? for example: i have a draggable red square on my stage. the stage is the bounds of the drag. if i drag the red square to the bottom of the stage and continue to drag outside of and around the stage, i'd like the red square to continue moving within it's bounds, following the mouse coordinates. currently, dragging halts as soon as i leave the stage and the red square only begins to move with the mouse coordinates if i reenter the stage bounds.
