AS3 :: Points & Lines - Getting Lines To Follow Points As They Are Dragged?
Jul 21, 2010
I am trying to create a mindmap where the user can drag points about the screen. I have gotten as far as drawing the line via actionscript, and drag+drop the points (defined as movie clips on stage). This is the existing script - I don't know how to get the lines to follow the points. Something to do with ENTER_FRAME or updateAfterEvent?
var line:MovieClip = new MovieClip();
line.graphics.lineStyle(1,1);
line.graphics.moveTo(ptOne.x,ptOne.y);
[code]....

line.graphics.moveTo(ptOne.x,ptOne.y);
line.graphics.lineTo(ptTwo.x,ptTwo.y);

I have a Flash animation that is entirely created with AS 2.0. It creates a line graph based on some data. It works perfectly as is, but I'd like to add a little flair. As it plots the points and connects the lines, I'd like to have a tiny pause between each. I'd like the user to see the line being drawn across the screen rather than it all appearing instantaneously.Is there any code that can make a script "pause" for a set amount of time?

I want to draw a curved line between random point. How can I do this? The random points are actually x,y positions of movie clips dragged on the stage and I want to code curved lines between them.
Im looking at curveto in as2 but not sure how to to do it?

I have a set of dots displayed on the canvas (key bits of code pulled out):
// Drop points based on x y coords
for (var i = 0; i < 50; i++) {
itemPoint[i] = new mcDot();[code]....
how to redraw the lines as I move a dot. Also there could be many lines connected to any single dot. Do I need to somehow register which lines are connected to which dot? How do I redrew the lines based on this?

How can i make a MovieClip object drag able by the mouse? If i have two MovieClip instances, is it possible to make a new shape/MovieClip objects in that looks like a line and which will connect then? I have functions checking if the 'nodes' movie clip instances collide with the 'line' movie clip instances, now these all are different functions and conditional, but is it possible to check if ALL of them are true?

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.

My code is on the main timeline.I call a function loop to draw lines between them.The lines are drawing between the right x, y values BUT between those values on the main stage, not those values within the kite.For example, dot1_mc is at x100, y0 inside kite. the line that should go from its center, draws from stage x100, 0.How do I draw the lines inside kite so that they draw between the dots?Heres my code that draws the linesPHP Code:
function loop():void{ lineDrawing.graphics.clear(); var a:Point = new Point(kite_mc.dot1_mc.x, kite_mc.dot1_mc.y); var b:Point = new Point(kite_mc.dot2_mc.x, kite_mc.dot2_mc.y); var c:Point = new

I have two lines. One is straight and one is curved. Both were created with the Flash Graphics interface. How would I compare the different Y value for the curved line for any given X. In other words, how do I find a point on curve if I used the CurveTo method.

I am following a good tutorial here:URl...And it uses the following example file to display an embedded FLV movie:URL...I am having a problem editing the cue points. If I open the compenent inspector for the FLVPlayback, and then open the cuePoints dialog, I should be able to add, remove, or modify cue points. However, I can't edit anything in the dialog at all. It seems locked.The tutorial clearly states you should be able to edit the points.

[URL]In the tutorial, it says I should be able to edit cue points for the FLV video. I open the component inspector and the cuePoints dialog. All the cue points are listed, but it won't let me edit them. They seem ti be locked. I need to be able to edit cuepoints within flash for a linked flv file.

I am SUPER confused on how to make use of the cue point that I embedded in my FLV.It is called "END", is at time 00:00:46.114 and is Event type.How do I go about calling an action, say loader.loadMovie("info.swf), when the movie reaches that point?

I have a function ( basically its the click on a reset buttons ) that sets back quite a loooooot of variables and text boxes. But after ( I think 200 lines ) , actionscript simply stops with that particular function and doesnt even give me an error.So it looks like there is a lines per function limit or something like that.I also tried it with an external .as but its the same.Creating functions for all these commands didnt work either.The only thing I can do is move a few lines up so that they get processed earlier.... ( but the last few still don't work )I even tried to make a function with 300 lines of myTextField.text = "hello"and a line: myTextField.text = "how are you" at the endDidnt work... it stayed at hello.

I am wondering about making lines with a corner radius. It seems that the smaller the scale, the corners sort of distort, and end up looking jaggy. Maybe its just the way it is, but is there any remedy? I tried shifting the registration points, etc, but still the only way it looks smooth is when enlarged.

I'm stumbling my way through designing my first Flex app, using Flex Builder 4 Beta 2. I'm trying to use a ComboBox, but they always seem to have lines around it and I can't figure out how to get rid of them. The ComboBox looks like this: [URL] All I did was drag the ComboBox from the Controls section in the Design section of the UI onto the screen. I haven't changed any settings, no special css, just used the default ComboBox and this is what I get.

Is there a tool that calculates various LOC statistics? It would have to support popular languages like C++, C#, Python, PHP, JavaScript, ActionScript, etc and interpret code accordingly.
An example of the statistics I'm looking for:
350 Physical lines of code -- including braces
200 Logical lines of code -- actual code
190 Comment lines
68 Variables
28 Methods/Functions
5 Classes
3 Namespaces

Just opened flash for the first time to find that the pen tool will only draw straight lines.It can still plot points and the lines will join up but curves are impossible.Is there some setting that disable drawing curves? I haven't found anything in the annoyingly-online files.

I need to translate this AS2 code into AS3 ASAP! how to translate a few lines from AS2 to AS3 [URL]I was supposed to make a flash 9.0 cs3 menu with buttons that stay down until another button is clicked.I've found an example of this on the net, one that is perfect in every way for what I need to have done.However, as always, there's a catch. The code on that site is written in AS2, which doesn't work for me because I'm using some functions which are incompatible with it (I suppose they're AS3 supported only, e.g. loaderComplete)

I am facing a curious issue. Generally when we draw lines in Flash either vertically or horizontally or through exact 45 degrees on either of the sides, they come out as straight and anti-aliased. While if they are drawn deviated from either 0 or 45 degrees, they come out as jagged. I want that to be anti-aliased too
