I have 9 images that are draggable on my screen - and when pressed become the top image- using the script below. I'd also like to constrain to a rectangle (or coordinates) - ideally adapting the exisiting script and movie clip set-up.

I am trying to created a constraint to a rectangle. I have the startDrag working and I am trying to constrain a square to the movie size of 600x400.I have been searching online help files but I can not for the life of me get it to work, would someone beable to put me out of my misery. I have attached the demo file I am working with but I will also post my script here for thoughs who prefer that...
Code:
("animation", false, 0, 0, 300, 300);

I'm doing a tutorial on using the startDrag function but have no idea how to get the coordinates for my rectangle.How do you find the 4 points? I've tried using my mouse to pinpoint the location but that doesn't work.Here is the generic code:myMovieClip.startDrag(false, left, right, top, bottom);
View 2 RepliesI have a small movieclip where an external image gets loaded into a custom shape mask. The user can then drag the image around. This is all working fine.
I am now trying to constrain the movement allowed so that the image cannot ever leave the masked area.
On my startDrag() function i have tried to include the following properties but i cannot get this to work:
(false,new Rectangle(-xpos,ypos,stage.stageWidth,0));
Code:
// Imports.
import flash.display.Sprite;

So I have a Sprite and if using startDrag(), how do I constrain the movement to x-axis only? that is, move it horizontally? The free x,y movement code sample is here, directly from Adobe's livedocs: [URL]

I would like Mouse to be constrained to the same area as ball during dragging, that is, when ball reaches a boundary Mouse will stop as well.

I'd like to figure out how to get these four skulls to move on a constrained X axis on enter frame, and on CLICK, I'd like them to reset to their original positions.Example:On frame 1 is an mc I created named holder. Inside there's an mc named box. Inside box are four mcs, circles1-4, inside the circles I have four skulls.I've also created an mc called rectangle and dragged it over the first skull to get the coordinates I want using the following trace:
trace(rectangle.x, rectangle.y, rectangle.width, rectangle.height);
Resulting in these coordinates: 143.95,119.05,131.15,61
So, this works MOUSE_OVER the circles

I want to drag one movie clip within specific region. For that I have created one rectangle with following
var rectangle:Rectangle = new Rectangle(52.75, 5, 100.25, 0);
Though I have given x position 52.75 ; i can drag movieclip to x position - 52.
I am noticing that if you let the mouse wonder away from the movie clip while dragging, it doesn't drop when you let go of the button. You have to click in the defined rectangle for the drag for the movie clip to drop appropriately.
How can I define my mouse movement to the same rectangle as the drag while the movie is clicked on and being dragged?
I have been trying to get this right for hours now it cant be as hard as I am finding it! but basically I have a circle and in that circle is a circle and all I want is for the inner circle to not be able to leave its parent. that's it but I just cant get it to work.

I have a pretty simple function here where I want to start dragging a video scrubber along the x axis within bounds, and drop it when they let go. The code works perfectly if I don't specify a bounding rectangle (except it doesn't restrict to x-axis). What's up with that? Here's my non-working code:
Code:
videoConsole.scrubber.addEventListener(MouseEvent.MOUSE_DOWN, dragScrubber);
videoConsole.scrubber.addEventListener(MouseEvent.MOUSE_UP, releaseScrubber);

I am trying to setup a startDrag in CS4, AS3 and can't seem to find the right syntax for it. The documentation says it should be:
startDrag(lockCenter:Boolean = false, bounds:Rectangle = null):void.
I interpret this as:
mc.startDrag(false, 55, 0, 648, 0);
Unfortunately I am getting the following errors:
1067: Implicit coercion of a value of type int to an unrelated type flash.geom:Rectangle.
1137: Incorrect number of arguments. Expected no more than 2.

I believe this is esentially a math problem that may be easy for most of the programmers out there, but I am stuck. I have a fixed rectangle width = 50 height = 50 centered in the middle of the stage. I am using this rectangle to copyPixels of a bitmap that is also centered on the stage. The bitmap is draggable. I can define the initial x,y of the rectangle used for copyPixels with

I'm working on a simple tutorial, and I'd like to randomly generate the positions of the red and green boxes in the accompanying images anywhere inside the dark gray area, but not in the white area. Are there any particularly elegant algorithms to do this? There are some hackish ideas I have that are really simple (continue to generate while the coordinates are not outside the inside rectangle, etc.)
View 2 RepliesAfter seeing the I've been told that movieclips aren't suited for games, what do you use? thread, I thought I would try to incorporate the approach into a game I'm currently programming to make it a little less processor intensive.
I have a giant movieclip of a football field, of which only 5-10% is shown at any given time. I'm guessing that flash still has to make calculations for the other 90-95% of the field every frame, even though it's of no use. From what I understand (not much), copyPixels seems like the perfect candidate for such a situation.
It seems simple, but I'm having trouble actually implementing it, and I'm not sure which actions are needed and what might be introducing unnecessary work. I have a movieclip (mc_field, exported for as), but if it would save the processor some effort,I could easily save this as a bitmap and export that for actionscript. The width and height of the final product (bitmap/BitmapData) will be Stage.width, Stage. height,respectively,and I can handle making the calculations of the x,y coordinates of the rectangle cropping (which part of the source bitmap I want to crop).I'm sure it's only 3 lines of code, and I know that there are a few examples online, but for some reason.
Say, for frame one, I want to take the field (either mc_field or bm_field) and copy 500px x 300px, starting at 140,230 from the source bitmap to mc_container.Then, for frame two, I want to copy 500px x 300px starting at 240,540 from the source bitmap to mc_container.
I want to accurately find out the top left bottom right coordinates of an object. Let's say an rectangle.
View 2 Repliesi 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.

For those of you still with me, I am tasked with making some scrollable content in Flash. Load in a TextFile using LoadURL(), then display it. To get the text, we've written our own class TextFieldExtended, which is basically just there to give the textfile location to the constructor and then have the class do the various steps of getting it and loading it for you.So I needed to get a Scrollbar, which I got hereThe thing is, it works with Sprites.After trying to get it to accept TextFieldExtended, I bumped into a block, since the scrollbar relied heavily on a Sprite property that TextFieldExtended didn't have or could have.
So I tried adding the TextFieldExtended instance to a Sprite instance using addchild.A problem occurs here that I do not know how to handle. It seems that a Rectangle is drawn and the Text is drawn on that. I say this because the scrollbar moves the Rectangle up and down a bit, but the text doesn't scroll, just the Rectangle it is positioned in and the text then moves along with it.My question: can this be fixed, or is does this implementation of scrollbars need a lot of adaptations before this is possible?
I draw a rectangle i should see a little bold circle to indicate a perfect rectangle, I seemed to lost mine, can somebody please tell me how to get it back!
View 2 RepliesI was trying to convert global coordinates to local coordinates of a UIComplenent in my flex project using below code using below code
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
uic is UIComponent in which I have subclass of Sprite for drawing something I have set the sprite's mouseEnabled and mouseChildren to false to not interrupt the mouse event. above code is within uic's mousemove event where I was tracing the gp and lp gp was giving correct value and suprisingly lp was giving negetive values. when I move the move to the top left corner of uic i expect lp to be 0,0 but it is giving the -width of of uic. I broke my head for hours and ended up finding an alternate by using offsets. Infact my original code was much simpler like this which was same issue
var lp:Point = new Point(e.localX,e.localY);
I am not sure what exactly is causing this problem. the workaround had lot of issues and it creating a mess in my rest of the algorithms.Just now I found even more interesting thing (which is actually weird). for some reason I went and create a new lp2
var lp2:Point = new Point(e.localX,e.localY);
now surprisingly it was giving correct values as expected and I went back and changed the code as
var gp:Point = new Point(e.stageX,e.stageY); //global point
var lp:Point = uic.globalToLocal(gp); //local point
var lp2:Point = new Point(e.localX,e.localY);
var lp2:Point = uic.globalToLocal(gp);
now it is expected to have all the lp, lp2 and lp3 variables to be same but weiredly lp two is giving wrong value and lp2 and lp3 were giving correct. I am suspecting using the variable lp has something to do. I am not sure about that but above proves it so right now I am using lp2.
I was reading the 'Isometric Transformations' tutorial by Danko Kozar and I have a few questions. I understand what all the code does, but not how it does it. First of all, how does the following code work:
transforms x,y,z coordinates into Flash x coordinate
xFla = function (x, y, z) {
// cartesian coordinates[code].....
I understand that it converts 3d coordinates to 2d coordinates, but I don't understand how. What numbers whould be punched into x, y, and z to acquire certain desired effects?Also, what's the difference between moveTo and lineTo:
red line
style(1, "0xFF0000", 100);
plot(0, 0, 0);
draw(200, 0, 0);
I am trying to convert a rectangle(actually multiple rectangles) to a curved rectangle. I think it should be pretty easy but I guess i am stupid. Basically I would have a start position and stop position (many of these), and they would be converted to curved rectangles and follow in a cicrle around.
View 0 RepliesI would like to create a rectangle inside of a rectangle, starting approximately 15% inward from the right side of the other rectangle.
I know how to create rectangles with:
Code:
var newHotRect:MovieClip = new MovieClip();
newHotRect.graphics.beginFill(0x00FF00);
newHotRect.graphics.drawRect(0, 0, 100, 100);
addChild(newHotRect);
But how would I make another rectangle on top of that (the black one pictured) that is approximately 15% from the right?
I toyed around with .right, and .bottomright with no success. Can anyone lead me in the right direction? or even finding the x and y of the upper right or bottom right side of a rectangle?
how to respond when a rectangle hits another rectangle? I already know how to detect the collision, I just don't know how to respond to it. I'm just trying making a simple side-scrolling platform game where I have platforms I can walk on and bump against on all sides. I have searched everywhere and just can't find the tutorials I'm looking for.
