ActionScript 3.0 :: Recover Coordinates Of Points Drawn With LineTo
Jan 20, 2011
I am developing a software in flash in which I need to draw some points in a movie clip dynamically with moveTo() and lineTo() during the runtime of the software. However, later in the future (during runtime), given the (x,y) coordinates of a point, I need to know if this specific point is part of the curve I drew before. Is there a way of doing that without saving the (x,y) coordinates of all the points I have drawn in the movie clip?

this is the thing: Using "lineTo" i get a line drawn on stage when dragging a mc. Then i should have four mc (note1, note2, note3, note4) added randomly over this line. I mean, the line is drawn and then over some parts of this line, using x and y of some of the points drawn there, this movie clips should be added randomly. I can make the mc appear randomly, but always in the same point (mouseX, mouseY); i cannot access others x and y of the drawn line. This is my code (noteContainer is a sprite):
Code:
private function drawingAPI(event:MouseEvent):void{
sprite1.graphics.lineTo(mouseX, mouseY);
}

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 have drawn a series of lines using flash's graphics.lineTo command, and placed them in an array to be referenced later. Based on certain user interactions, the clips that hold these lines can be shifted to the right, causing the lines to move with them, no longer connecting to the point they originally connected to. So I need to extend the lines by the amount their parent clip was shifted (I've called this incVal). So what I need to do is find the point at which each of these lines ended at, and draw from that point to the left by incVal. How do I get that ending point of the line?
This is my code:
To draw line and add it both to the clip and to an array for future reference:
line.graphics.lineTo(localPoint.x,localPoint.y-10);
membersRef.addChild(line);
parallelArr.push(line);

I am trying to draw a line from x1, y1 to x2,y2 and i want it to be a line that repeats a pattern from an image. All I can see is that you can only draw lines and change their color or thickness but I would like it to repeat an image. Is that possible or do i have to use a really long and thin rectangle with a bitmap fill?The problem is I am making a game where the user will be able to actually draw the line so i have to make it be created dynamically. The game fantastic contraption [URL] has in the game a feature where you draw lines of any length and position that are filed with a picture.

I'm looking to work out the most efficient way to maintain the joining of two points with a line in AS3. Basically, I have a whole bunch of circles that move around, and have a property subNode which will act as an end point for the line. At the moment, the way I'm doing it is extremely intensive:

Is it possible to draw a path in flash, and access the points from AS?For example if I have a map and I add hidden paths along various roads, I then later want to animate traffic or growing lines along these predefined paths from code.

I'm in the process of making a board game in Flash; as part of process of getting fully to grips with Flash AS3.
I have a JPEG of the original board. This contains ~ 1000 circles that players may move pieces between. Pretty standard board-game stuff. The circles are not in any way regularly spaced.
So far, I've drawn the circles in Flash, by hand, and positioned them where they need to be. This looks great - I can see all my places.
What I want to do now is create these circles programatically. I want to be able to do this so I can adjust how the spaces look (depending on game state). Eventually I'll want to be able to zoom / pan the entire game board as well.
My question is, is there a way of tagging each circle with a unique reference and then looping through and recording locations?
I'm thinking something a bit like the Javascript DOM "getElementsByTagName" or similar.
At the moment I can only see two options:
Convert each circle to a symbol and give it a unique class name so I can access it from code Go through and write down the X/Y of each circle (add to my DB of board locations that I already have) so I can plot them programatically

I was working on an animation for a project and Flash told me it couldn't save and Save As wasn't working. The program crashed and the file I was working on was corrupted. I doubled my effort on getting back to where I was on my project, being extra careful not to do what caused it to crash before. Unfortunately, fate was not on my side, and it did it again. Obviously I'm screwed, but still I like to keep on to my projects and upload them to megaswf or something to share on facebook. I'm using CS5 btw.

I have a page (MovieClip) which is charger and have a attribut a matrix (not the class). On this page, there is some cases (MovieClip) which receive value of the matrix.
Each cases are managed by Class. It's a good option, because I can put a listener into the contructor of the class and not having 64 functions if I have 64 cases. This listener allows to change the value of the cases when it clicked.
The problem is that I don't see how to know when a case is clicked in the page for changing the value of the matrix.

Using Adobe Flash CS3 on a sometimes dual monitor setup. After attaching back to my docking station, and starting up Flash CS3, the window is off the edge of the right hand monitor somewhere, and I am not sure where. The mouse cursor makes it look like the window is somewhere off the lower right hand corner of the screen somewhere, but even after holding in the left and up arrows for a long time, there is no motion, and the window never appears. I can maximize the program back to my primary monitor, but this is hardly an ideal solution.
I have found the following registry entry, but am unsure if it applies to what I'm having problems with or what the format of the entry is: HKEY_CURRENT_USERAdobeFlash 9SettingsWindow

How can I access to an object who fires an eventListener event?
Let's say I have a mc:
var element = new MovieClip();
which has an eventlistener:
element.addEventListener(MouseEvent.CLICK, elementEventHandler);
[Code]....
So that is what I want to achieve... Recover the object who fired the event and then do crazy things with it (in this example, add another object in it).
pd: yes, I know I can directly use the var element in this snippet, but in the real code I'm generating the mcs in a loop, according to a xml file.

My Flex app uses local SharedObjects. There have been incidents of the Flash cookie getting corrupt, for example, due to a plugin crash. In this case SharedObjects.getLocal will throw an exception (#2006).
My client wants the app to recover gracefully: if the cookie is corrupt, I should replace it with an empty one. The problem is, if SharedObject.getLocal doesn't return an instance of SharedObject, I've nothing to call clear() on. How can I delete or replace such a cookie?

I 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 have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:
The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.

I am making a demo where an object is moved around the screen with a line tracing its movement. The speed of this noticeably slows down over time. I tried it both with an enterFrame and by setting an interval. I imagine it has something to do with the graphics class vector drawing and garbage collection. Here is a simplified version for demo/testing. If you run it you will see the line drawing slow down over time. Is there a way to achieve it without the slow down?
I read somewhere of a technique where you use the bitmap data class to draw on a stage-sized bitmap.(I've never programmed the bitmap data class before).
Here is the code:
code: var lineX:Number = 100; var lineY:Number = 100;
var deltaX:Number = 10; var deltaY:Number = 10;
var lineDrawing:MovieClip = new MovieClip();
this.addChild(lineDrawing);

I'm making a shape (christmas tree) which i can't make with rectangles and circles exc, so i made it with moveTo/lineTo, the problem now is that i can't "call" for it to fill the area inside the shape... how would you do it? Also, i hope i did this the wrong way, because its a really tiresome way of making it. What I've got so far is:[code]

I have been working on a drawing "game" in my spare time (which is limited). This is probably a common question, if so I appologize. By the way, I do not have the code here, it is on my other computer. Anyway, I was using the lineTo method and a timer listener to fire the addition of each new line segment, if that makes sense. The problem is that when you try to draw an arc quickly, it looks terrible. It draws straight lines. I tried adjusting the timer, which helps a bit but still not great. I looked at the curveTo but could not figure out a logical way to get the achor coordinates. I did some research online and found some that use addChild with bitmaps. I would rather use lines. Has anyone tackled this before?

function leaderRT(e:MouseEvent){
if(flag) {
graphics.lineStyle(1, 0xCC00FF);
graphics.lineTo(e.localX,e.localY);

I want the sound to be played until the line is drawn. Wat modification has to be done ? Also when I execute the above file I get the Stream error ?
