ActionScript 3.0 :: StartDrag With MouseEvent?
Sep 24, 2009
I've created a function called dragItem() that I call with the MOUSE_DOWN event. I've got it working....kind of. I can access the function when the mouse is clicked and I can even get the name of the instance when the mouse is down. I'm trying to use the same logic to get the single object to allow a drag. see my code below...
function dragItem(event:MouseEvent):void { var instName:String = event.target.name; trace(instName); trace(event.target.width); event.target.startDrag(); event.target.removeEventListener(MouseEvent.MOUSE_DOWN,dropItem); event.target.addEventListener(MouseEvent.MOUSE_UP,dropItem); }
I get this error when I try to drag the item...ReferenceError: Error #1069: Property startDrag not found on flash.display.Loader and there is no default value. at Main/::dragItem()

i have an .as class that extends mx.containers.Canvas (it's a draggable border of a resizable component), it becomes draggable on MOUSE_DOWN and stops being draggable on MOUSE_UP, MOUSE_OUT and ROLL_OUT. before calling startDrag() i create a Rectangle to define the drag area, i also have a _dragging: Boolean variable to control if it's draggable at the moment. the problem is that when i click this border it jumps to a negative coordinate without calling startDrag or switching _dragging to true.
i've overriden get x, set x, get y, set y and move() methods in order to solve it but the only thing i got was the fact that position changes without calling coords setters or move(), but at the moment it's changed a getter is called and returns new (negative) value so my question is what happens on startDrag() and how to filter unwanted incoming coords values?

as you can see, I have a container MC which I have added to the stage. I set its drag constraints using a Rectangle(). I then add the 'cat' child movieclip to the container, and I want this to be dragable too. However, as soon as I click on my cat when testing the MC. It shoots to point x=0 y=0 on the stage and doesn't move.
The container MC can be moved without any trouble.
If I remove the rectangle bounds from the containers startdrag() function. both MC's can be dragged without any issue.
//panning ability
my_x = 800 - myImage.width;
my_y = 480 - myImage.height;

I have several stage event handlers to enable mouseovers over several dynamically generated moviecilps on the stage that then change their alpha to indicate the mouse is over that particular mc... fairly trivial (mcOver handler). Additionally, I also want to know what MC is clicked, so I update a public variable (public var activemc:Number) with the ID of the dynamic movieclip when the mouse is over it (using a hitTest to check, which is why the EventListener is added to stage and not to the MC), which is checked in the mcClicked handler:This is in the constructor:
//stage.addEventListener(MouseEvent.MOUSE_DOWN, startDrawing);
//stage.addEventListener(MouseEvent.MOUSE_UP, stopDrawing);
stage.addEventListener(MouseEvent.MOUSE_MOVE, mcOver);[code]....
However, the mouseover behaviour (alpha 0 when over, alpha 1 when out) stops working as soon as I click on any movieclip on the stage, and the mcClicked ID checking (below) stops working completely. I don't know if this is to do with focus:
private function mcClicked(event:MouseEvent):void {
myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID
}
I then tried adding the event handler for the stage mouse_move again and this gets the mouseover working again but only for 1 more click, after which it stops again:
private function mcClicked(event:MouseEvent):void {
myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID
stage.addEventListener(MouseEvent.MOUSE_MOVE, mcOver);

I have a MovieClip (call it base_mc) which is under a bunch of other MovieClips (call them subclips). The MovieClips on top are all mouseEnabled with MOUSE_OVER, CLICK, etc, event handlers. I want to capture the event of MOUSE_OVER (or ROLL_OVER) on the base_mc as well. Any time I am over one of the subclips I am also over the base_mc clip. How can I capture this event?

I'd like to know what is the difference between MouseEvent.CLICK & MouseEvent.MOUSE_DOWN. Because when i use MouseEvent.MOUSE_DOWN for a button to set full-screen view its doesn't work, instead of this MouseEvent.CLICK works. So what was the reason.

I'm making a button for the first time, and I wanted to use a full click to drive it. However, when I use addEventListener(MouseEvent.CLICK, onClickHandler); nothing happens when I click on it. When I use (with the rest of the code being identical) addEventListener(MouseEvent. MOUSE_ down, onClickHandler); it works like a charm.

What is the difference between MouseEvent.MOUSE_UP and MouseEvent.CLICK? Why should I use one of these over the other?
Code:myButton_btn.addEventListener(MouseEvent.MOUSE_UP, fNavigate, false, 0, true);
myButton_btn.addEventListener(MouseEvent.CLICK, fNavigate, false, 0, true);

I have a MOUSE_DOWN handler that creates a CLICK event listener on a child object. Naturally, as soon as you release the mouse button, if you happen to be over the child object, the CLICK event fires.I was disappointed to discover that event.stopImmediatePropagation doesn't interrupt the CLICK event from registering the MOUSE_DOWN as part of its detection cycle. It makes sense that it doesn't but still... disappointing.A MouseEvent.CLICK consists of detecting a MOUSE_DOWN on the object and then if it's followed by a MOUSE_UP without leaving the object, he event fires. I had hoped that by cancelling the MOUSE_DOWN event, it would clear that out of the CLICK buffer, but no such potatoes, alas.This could all be handled with a flag and a couple more MOUSE_UP and MOUSE_DOWN handlers, but dang, smacks of effort

I have the following:
rwBtn.addEventListener(MouseEvent.MOUSE_OVER, audioOver);
function audioOver(e:MouseEvent):void
{
var thisClip:MovieClip = e.relatedObject;
thisClip.alpha = 0;
}
I would like to change the alpha of the clip that is being rolled over. I don't know how to target the clip that is being rolled over. How do I do that?

is there a way to drag multiple movieClips at the same time? Flash help explicitly says: Only one movie clip can be dragged at a time. After a startDrag() operation is executed, the movie clip remains draggable until it is explicitly stopped by stopDrag() or until a startDrag() action for another movie clip is called. anyone know of a way to do it anyway? maybe combining them in a dynamic mc or something?

The Language Reference states:
"Three-dimensional display objects follow the mouse and Sprite.startDrag() moves the object within the three-dimensional plane defined by the display object. Or, if the display object is a two-dimensional object and the child of a three-dimensional object, the two-dimensional object moves within the three dimensional plane defined by the three-dimensional parent object."
However, this does not seem to be the case. I have a 2D object which is the child of a 3D object, but startDrag will not work on the child. If I remove any tweens in code from the parent's rotationY then startDrag will work. If I have any reference to rotationY it will not work, even if it is set to 0.

I have an index file in which I load my external .swf. One of the external .swf has a drag and drop quiz. And as you can guess, the startDrag doesn't work! In fact, when I publish within Flash it works just fine, but when played within the index file, it stops working!
For your information : all my files are in AS3.
So here's a bit of my code.
var interbouton : Number = 10;
//I have 7 items that I can dragfor(var i:Number=0; i<7;i++){ var dragBtn :MovieClip = new Drag();

I have noticed when setting a bounding box on a drag object, if you go outside the bounds of the box you have set, the mouse won't let go of the object unless you go back inside the bounds and click on it again. Is there any way to force the stopDrag if you go outside the bounds while dragging? I have tried this bit of code:

I'm making a strategy game the uses a tile map to show information about the other players! Every tile is 50*50px and when you start the map it loads about 50 tiles and puts them together (all this from a Flash->ASP->MySQL which i managed to do on my own)
What i need to do is to make the map draggable (kinda like maps.google.com) and make every tile clickable! I can't manage to do both of these things at the same time All the tiles are in a movieclip called mapMc so by creating a big button above the visible map area and write:
ActionScript Code:
on (press) {
allSize = _global.fullMapSize/2; //This gets the size of the map after all tiles have loaded[code].....
And that kinda works (except for the boundaries)Second, when you press a tile, which i stupidly constructed as another button, so every tile is a button (loaded dynamically) with as that fetches the tile information (already fixed ) But how do I combine them?

I have a MovieClip with other MovieClips inside of it. On each of the MovieClips inside, I have added a MOUSE_DOWN event and in the handler, I call e.target.startDrag(false, null);
But it doesnt seem to work :/
I have traced out the target name. I have tried current target and traced out it's name. THey both trace correctly. The target is being reached and it is the corect target. But the startDrag function doesnt make the MovieClip draggable.

I've got a zoomable map within a frame, and of course I don't want it to be dragged out of view, right?
So, how do I set the startDrag (L,T,R,B) parameters when it's a different size when it's enlarged (zoomed)?
Would it be advisable to somehow set multiple conditions to do something like this? (if so, how would I do it?)
if ( between Size>100 AND Size<200) {
startDrag(this, false,400,150,600,250);
}
if ( between Size>200 AND Size<400) {
startDrag(this, false,500,250,500,150);
}
Would it be advisable to do something like that? If so, how would I code it?
If not, what would be a better idea?
...I swear, adding this zoom feature added a whole level of complexity to this map that I've never imagined.

If you drag the map, it moves even beyond the edge of the map so the map eventually gets dragged off the screen. Is there any possible way to stop the map moving any furthur than its boundry?

It does dupllicat the Movie Clip but I can't drag the duplicate.I learned this from a very old Flash lesson. I wonder there is a new way to write it now.

I'm trying to work with a movie clip that I am loading into my main SWF. When run alone the draggable rail works fine but once loaded into the actual main SWF it won't drag. I put an on EnterFrame on it so that when I click it reads out some data and that still works within the main swf. Is there some sort of restriction on what loaded content can do?
import flash.display.MovieClip;import flash.events.MouseEvent;
var upper_left = rail.x;var upper_top = rail.y;var travel = rail.height-handle.height;
