ActionScript 3.0 :: Using Bounds In StartDrag If RotationX Property Is Changed?
Sep 26, 2010
I've created a flash card class in ActionScript that uses a tween to flip the card over the y-axis (i.e., by using rotationX). I also use the bounds property of startDrag so that, when you drag it, its movement is locked on the x-axis. (There's also a method for switching between dragging and flipping, but since that's not broken, there's no need to discuss it further).
Here's my problem. If I haven't yet flipped the flash card over, the card drags fine. If I flip the card over and don't use bounds in startDrag, it works fine. But if the bounds property is set and then I try and drag the flash card after it's been flipped, the movement goes all haywire. It basically jumps back and forth between the two ends of the bounds' rectangle.
Is there any way you can think of to solve this problem? Alternatively, is there any way to use sprites to limit movement? For example, would it be possible to place a pair of one-pixel-thick horizontal lines on the top and bottom side of the flash card, set their alpha to zero, and somehow stop the flash card from moving past the lines?

I created a full flash template website loading external swf's.Lately, I managed to add a fake3D rotation with AS3 and CS4 to this global template with enterFrame.Problem : some of my external swf use a vertical scroller also using an enterframe function based on a startDrag bar with the x / y position of the mouse, the scroller dont work anymore.

I am trying to make this an kinda interactive map in flash. I will try to explain it for better explanation. Here is an image of the output I have a jpg image(converted to movieclip) which is way larger than the stage.
[code]...
Then I have a mask in the center of the stage and user sees a portion of the map and is allowed to scroll to move mouse around to see areas around the focused city.
[code]...
I put this numbers in by playing around but where are these values exactly coming from. I have tried everything(every possible way) but cant figure out what are these values. I need to numbers to be dynamic so I can change the focus to different cities(for example when a user click A city A should be seen inside the mask and so on).How can I make these values dynamic instead of hard coding them.

I have a large movieclip (2336 x 1752) and a stage of 800 x 600. I want to be able to drag the movieclip around the stage so no white is visible:
minimum x before I get whitespace: -1536
minimum y before I get whitespace: -1152
maximum x before I get whitespace: 0
maximum y before I get whitespace: 0
I have tried this:
Code:
var mcBounds = new Rectangle(-1536, -1152, 0, 0);
mc.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
mc.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);
[code]...
But it doesn't drag at all...when I try it just moves it to it's maximum position and stays there.Is it because the rectangle can't have negative values?

I have an image which I have converted to a movieClip, I have exported the movie clip as an AS class and have some code in the class which adds some text to the movieclip. What I want to do is rotate the movieclip around the y axis but I get the following error:
ActionScript Code: Error #1069: Property rotationX not found on classes.LargeCard
How can I rotate the movieclip without using the timeline?

I have an image on the stage which is bigger than the stage itself:
The stage is 700x550
The image is 2100x1650, and it's registration point is at its center, if I remember correctly.The initial location of the image on the stage is 350,75.I want to make sure that the user will be able to drag the image, as long as the edges of the image doesn't show.here's what I did:
mapRect = new Rectangle(0-mapMC.width/2, 0-mapMC.height/2, mapMC.width, mapMC.height);
and later on:
mapMC.startDrag(false,mapRect);
The the top and the left of the image are bounded well, but as far as the bottom and the right side of the image.

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;

When I use 3D rotation tool, there is an option called global transform, if it turned off, the object would rotate by its own axes, this is exactly what I want. How can I do rotatation like that with AS3 code? Is there any property if changed then rotationX/Y/Z would rotate object by its axes?

I have to use Flash CS3, so I can't use the properties rotationX, roationY and rotationZ.I have a movieclip, that looks like this. It is now flat, no 3D rotation or shearing But what I want is that this movieclip has a rotationX, or that it is a bit in perspective like this: As I said, I can't use rotationX, so I have been playing around with Matrix. But I can not get it right.Here is how I try to do it
myMC.transform.matrix = new
Matrix(1,0.15,0.35, 1, 0, 0);
And this is the result get the matrix right, or is there another way?

when you rotate fe. with greensocks engine on the X/Y/Z axis with text movieclips, the final state is never crisp with me.lets say your clip is at rotationX 30and tweens to 0 , in other words it starts at an angle and displays full frontal at ends. no matter what i try, the font has certain parts crips, certain parts blurryI've been spending this sunday with all different kind of fonts, embedding, textfields, fontsizes (as you know certain fonts have their "sweetspot" size, etc, etc, etc, it just doesn't get sharp after the rotation.Funny enough, when i trace out my rotation angle it says 0i even tried an onComplete event to force its properties to zero. but to no avail.
could make a bitmap data file from my text, but come on... why do they implement 3D while the results are off? Really would like to hear some tips here because i am tempting to go back at away3D. I was hoping with flash CS5 their 3D render for textfields would be alot better compared to "crash"Cs4Yep theres a slight annoyed undertone here. To me, it should be fundamental or at the very least, tweak-able like image resizing with "smoothing".

I'm encountering a weird phenomena. I have a multi nested display object structure. Some of the deeper display objects have MOUSE_CLICK events. But as soon as I set main display item container.rotationX = 5 then the mouse events don't work anymore.

I don't know if this would be more appropriate under the 3D forum but it could go either way. I'm having a problem: when I access the 3D rotation properties of a DisplayObject (specifically a MovieClip containing a Loader and some TextFields), it becomes bitmapped and loses its scalability. Is this supposed to happen, and is there a way to regain scalability after rotationX/Y/Z are set to 0.0?

i am playing around with the rotationX/Y/Z properties available in flashplayer since version 10. for testing purpose i created a cube and put canvas objects on three sides of it (top, front, bottom) and created a tween to get the values required for turing by 90 deg. turning the cube (a canvas) using rotationX = xx works well when the three side-canvas objects are small and filled with a not-to-complex element hierarchy. when using larger and more complex content it slows down. the next idea was to remove the canvas elements content and replace it by a snapshotimage of the content instead before starting the turn, after the turn is performed the original content is put back on the sides again.
this results in a good perfomance increase. using a tween the last step of rotation is done in the function that is called as the tweenEnd handler. in this function also the process of copying the canvases content back is performed. unfortunately this results in a short hang of the cube right in that last rotation step, the reason for which is that rotation and copying back takes place at the same time. so i could wait for some time after having called cube.rotationX = endValue by using a timer or setTimeout(func, 500), but this is ugly. so my question is: after having called cube.rotationX = endValue a period of time is required to calculate data for the rotation and do the rotation itself. is there a way to find out the point in time when the rotation has ended, so that then the copying can be started ?

I'm using(tweening) the rotationY and rotationX properties on movieclips a layer above a background, bitmap or video, in two respective projects. There is a flickering of the movieclips and some bizarre distortion going on. I can't seem to find anything on the web about this, -has anyone else encountered this problem? Is it a known bug? Is there a workaround?

Any smart people out there who can tell me why this function Im working on to automatically sort the depths of objects placed on the 3D plane is only working intermittently? It seems to work every second or third iteration?[code]Is getChildAt(i) reliable? IE does it return the same order each time it runs or is it based on depth? looking at the manual suggests that it's probably the latter so I guess I'll need to make my own array ordered by the time the sprites were added to the parent and work from there. Is there a better way?

Although I put _x = player._x etc. code in an onEnterFrame function the masking mc is moving without the player
You see...the player is held within some borders. When cornered and then hit, the mask moves according to how it would move normally, but without the player (because he is held in place by some borders)...
Also, if I don't have a problem but I'm missing a crucial piece of code,
code on masking mc
ActionScript Code:
stop();
this._x = _root.player._x;
this._y = _root.player._y;
radiance = 180 / Math.PI;

I have a bunch of images going on all at once, some on the stage, and some off, and i would like to find a way of telling whether or not they are currently on the stage or not....
I know i can do the whole
checkStage = function () {
if ((mc._x>=0) && (mc._x<=Stage.width) && (mc._y >= 0)&&(mc._y >=Stage.height)) {
//have mc do whatever here
[Code].....
that way i can satisfy my laziness AND achieve what i'm trying to do without having to deal with long winded paths and a bunch of else if's

I have a movie clip which I have set its rotationX property to -45. This gives the illusion of 3d. It is skinny in the back and fat in the front. I now want to add thumbnail clips on top, but can't figure out how to translate the original clip's x and y properties back to the 2d world.
