How can I animate a curve being drawn with as3 drawing api.I am not interested in masking it out or other tricks. I am interested in drawing it whith the api.This would be the equivalent, but only a straight line:
var steps:Number = 30;
var currentStep:Number = 0;
var startPoint:Point = new Point(100,100);

I have a world map on which I display some data. I read long and lat coordinates for two countries from an XML file which is updated with different coordinates everytime. I then map the coordinates to X-Y axis using some projection method.
So, I have x-y coordinates for two countries. I wanna draw a curved line between those countries but curveTo method draws the curve in one shot. I want to animate the curve drawing part so it looks like it is being drawn real time.
I'm trying to draw a curve based on 24 data points. I want to draw a curved line based on the average of these 24 points. I can draw a line from point to point no problem, but would like a smooth curve. The white dashed line is what I'm trying to achieve:

View 2 Repliesso maybe this animation is not that cool. But line 'draw-on's like this are quite common and I cannot find an easy way to do this in flash. I have tried masks, but (as far as I can tell) the line path is too complex for a mask. I have tried animating it using shape hints, but flash just gets hopeless confused as to how I want the line to animate on. I could export this as an swf out of AfterEffects, but the file size seems way too big for what the animation is. I have begun to realize that maybe this type of animation is often achieved using actionscript.
View 8 RepliesFrom the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?

View 3 RepliesI was hoping someone could help me working out some advanced data reformatting. What I'm hoping for is a function where I can input a value along with an array of key positions like so:
function remap(percentage:Number, keypoints:Array) { ...
The array would start with the minimum and end with the maximum point, with nested key points along the way. For example, I would input something like remap(0.25, [0:0,80:50,100:100] ) and the function would 'imagine' a spline curve graph from (0,0)-(100,100) with a key point of (80,50), then return the y value that is 25% along that graph.
I'm trying to animate a line by drawing using tweenmax and lineTo, but flash seems a little confused about the coordinates of things. The lines are also drawn a little shaky. Here's my code:
var childArray:Array = new Array(sC0,sC1,sC2,sC3);
var curChild = 0;
function drawLines(){

I have a curveTo an anchor point and a control point.Then I have a function that will return the x and y of a point along that curve if I give it a number as a percentage of the curve (0 to 1).It looks like this, and works perfectly..
Code:
function drawOnCurve( interval:Number, x0,y0,x1,y1,x2,y2)
{
interval = Math.max( Math.min( 1, interval ), 0 );[code]....
x0,y0 are the start point, x1,y1 the control point and x2,y2 the final anchor point.But... I want to give it a _y value instead of a percentage (interval) and it return where on the curve that would intersect.
I have been tyring to export an animated banner, in animated.gif format. it's a simple animated text with no gradients. it should go on top of a graphic which has some gradients and is multi-coloured and with effects (the colours are similar to the one/i used in the page) as you can see here the text looks a bit funny.url...

That's several years I'm working with Flash, and today, i want to do the simplest animation ever, and it just doesn't work....I want to mask an animated clip with an animated mask (a shape animation), but every time the mask arrives at a keyframe, the clip restarts to the frame 1 !!I added a piece of code to see at which keyframe it is blocked, and at every mask keyframe, the code says 'TypeError: Error #1009: null property..

View 1 RepliesBasically I've got a reasonably complex drawing object in a fla and I want to reproduce it in a class definition using the drawing api. However obviously this is a tedious task, so is there some trick or automated method of doing this?
Last time I needed to do this it was a drawing of an arrow and I ended up writing down x,y,width,height values for everything but this one has curves in it which I don't have experience with drawing anyway.
I cannot get this to work. Without the "var drawing", "var drawing being true or false" and the "if statement", it works fine. But I need to add the "var drawing" so that you can only draw if you turn it on by pressing the "draw_btn" button. Note, I do not get an error, the script "apparently" contains no errors. Here is the code:
ActionScript Code:
var drawing = false
_root.createEmptyMovieClip("myLine", 0);

I've created a drawing tool which allows the user to draw on the canvas, the problem is that if I try to draw over a movieclip nothing happens. Is there a way I can allow for the user to draw over movieclips? For example if I had a background of paper?
Here's the code I'm using for it:
// This code is for drawing the lines on the page
//1.
var drawingLine:MovieClip = new MovieClip();
addChildAt(drawingLine,0);

View 1 RepliesI need to draw on stage about 40,000 4x4 squares each a different color. The color is determined by an xml file. I have this working in as2 and have converted it to as3 the problem is the amount of time it takes to draw is causing cs4 to time out. I have extended the script time out to 60 seconds. In cs3 as2 it would draw the squares in about 15 seconds. I was hoping as3 cs4 would improve performance but seems to be the opposite. I have tried several methods such as adding children and various drawing variations. the bellow seems to work the best, but is still causing flash to crash.

I am using the code attached below to make dynamic text curve.
My question is: How can I invert the curve or arc, while making sure that it still reads the same? up to down.
I use Loader class to load a picture,such as example.jpg,and I know if I want to realize fade in effect,I can use following code in Event.ENTER_FRAME:sprite.alpha+=0.05.When I run above code,I can get a fade in effect of example.jpg. But the fade in effect is for the whole example.jpg, now I want to fade in the example.jpg with a special curve,such as number 9,the example.jpg fade in along number 9 curve. I guess it shoud have a mathematical model can realize this special fade in effect,anyone could give me the model of fade in along special curve?

The curve decided by the width(X on the picture) and height(Y on the picture) properties of a movieclip.The distance between each green point on curve is the same.
what I am trying to do is calculate the position of a point along a curve, what I want to do is create a function where i am able to determine where a point intersects the curve when I provide an X value.I have created a simple diagram to illustrate what I am looking for:So assuming I know the x,y of each black dot, and the x of the red dot, how do I calculate it's y value?
