if you look at [URL] and check out the amazing background it has! how to place flash background, i know how color changing works, but how does the flash draw the randomly curved lines with gradient, and moves up and down? here is the link to the background flash [URL] as far i can tell, the lines are done purely in action script, because the whole thing is only 47kb

I made this one poor class that has a public function which draws with a single loop a shape with curveTo() function (I tested one option to draw straight lines with lineTo() and only curved lines with curveTo() function but in my opinion, that lineTo function where a bit slower, at least in my implementations of testin speeds).I sent to it four parameters (anchor points and the control points) as many times as there were some corners to draw and everything seemed to go well untill I checked which way is faster to draw single rounded rect. Flashs own way beats my version up with huge 120 m/s distance already in some 100 000 iterations. The format of data I tested to send to my class function to draw that goddamned thing were numbers in arrays, numbers in objects and numbers in my own class objects like linked list and the file that holds just four numbers included in arrays or linked list. And two separate arrays, one for anchor points and one for the control points, with just Point Objects were fastest (if I remember correct) way but still that 120 m/s slower than Drawing API in Flash.My function in the class where something like:
ActionScript Code:
public function drawShape(points1:Array, points2:Array, lineOn:Boolean = false, fillOn:boolean = false, lineThickness:Number = 1, lineColor:uint = 0, lineAlpha:Number = 1, fillColor:uint = 0xff, fillAlpha:Number = 1):void{[code]..........
I'm trying to draw this hint box and was wondering if anyone could explain to me how to draw a curved line like the one below in flash?
View 4 RepliesAs a UI specialist, I am often asked to build tool-tip displays and other sorts of popups that display text. One of styles clients seem most keen on is text in a comic-book balloon. I would like to create this balloons programmatically (as opposed to embedding or linking to rendered graphics), because these balloons will have to change size at runtime, depending on how much text they have to hold.
Balloons are easy to draw for the most part: circles, rectangles or rounded-corner rectangles. The tough part, for me, is the tail (the little arrow-like part of the comic balloon that points towards the speaker). If you google comic balloon, you see that there are many varieties of tails. They ones clients request from me most often are curved. E.g...
[URL]
The tail will always be on the bottom of the balloon, and it will sometimes point left and sometimes point right. I have been trying to come up with tail-drawing algorithms for a while, but I'm not happy with the results. I'm basically stumbling around in the dark, changing variables, looking at the results, and using trial and error to try to move closer to the magic numbers that will work. "Work" just means a result that looks pleasing, which I realize is subjective. Most of my clients will be a happy with anything that looks reasonably good and professional.
I want this result to scale. And it would be great if it could work with as few inputs as possible, maybe just isFacingLeft, tailWidth and tailHeight (Which could maybe be a percentage of the whole balloon). Maybe an adjustable curveAmount.
If it matters, I'm using Flash/Actionscript, but any system that has some sort of turtle graphics engine should work pretty much the same way: I'm working with that standard flipped Cartesian grid (y increases downward), x and y coordinates, the ability to move a pen, draw lines and draw curves.One caveat: Flash only allows me to draw 3-point bezier curves -- start point, control point, end point.
Note: balloons won't have to scale after the are drawn.
I have been working on a map viewer based blitting technique. As part of the map I need to draw approximately 50000 lines and performance is currently really poor.

Im looking at curveto in as2 but not sure how to to do it?
Here's the effort simply displayed: http:[url].....it uses curveto to show the arc of a doorswing.I'd like the drawn arc instead to appear/trail along the leading edge of the door _as_ the door swings open. Guide Layers AS2 led me to tweening AS3 class but the beginning and end objects weren't right. Am I in the wrong place? This seemed somewhat straightforward but perhaps I'm searching for the wrong keyword(s.
View 4 RepliesI am trying to draw a continuous curved line in flash. There are many methods but none of the ones I have found so far quite fit my requirements. First of all, I want to use the flash graphic api's curveTo() method. I DO NOT want to simulate a curve with hundreds of calls to lineTo() per curved line segment. It is my experience and understanding that line segments are processor heavy. Flash's quadratic bezier curve should take less CPU power. [code]...

View 1 RepliesI'm using gotoAndStop(); for my buttons within flash using the following method:
myButtonInstance.onRelease = function() {
gotoAndStop("frame5");
}
however, I've come accross a problem where in for some reason the application will sometimes move frames when I don't want it to. For example, given the code above it would sometimes go to frame 5, but then instantly move somewhere else from there despite the code saying only to do so when a button is pressed.

View 2 RepliesI am trying to draw a box shape on screen which fills with a gradient, but according to the angle between your start and end mouse points. ie, if you draw from 100x100 to 200,200, the angle will be 45 degrees and it will draw your gradient fill within 100x100 to 200,200 on a 45 degree angle.
Trouble is, I can EITHER get the angle working just fine if I fill the entire shape, or the angle isn't right but the fill area is correct. Please see the attached fla and click drag within the red box, trying out the 2 matrix arrays in thereto see the 2 x scenarios listed above.
I am trying to have a line draw in my movie with actionScript...
have made three lines.
if I want line 1 to draw.... then..... line 2.... then line 3
do I put the script on three separate frames ?
and.... right now... they are just there...
how do I make it like an animation where the line starts at the edge of my movie draws line 2 changes direction draws line 2 changes direction draws line 3 then stops.
anyone know why this isnt drawing lines for me?

I'm trying to create spinning rays in actionscript to use in my website.Below is the rough idea of what i'm trying to create.Is it possible to create absolutely with 0 images.Following is the actionscript code in which i couldn't figure out how to add gradient, transperant background and little radial gradient to create glow effect.
Code:
function CreateRays():Shape {
var ray:Shape = new Shape();
ray.graphics.beginFill(0xFF9900,.5);
ray.graphics.lineStyle(1,0xFF9900,.5);

If you paste above code in 1st frame of your scene with nothing on your scene, it will give you sweet rotating rays!
I'm trying to draw lines on a canvas object. When the width of the Canvas is less that the width of the line, it draws outside the Canvas over other elements. I read about this problem and I try to resolve using a inner Canvas with a longer height so a scrollbar appears.But I also read that this problem can be correct using a mask but I do not know what is the better way. Which do you recommend?

I would like to have a possibility, where a user could draw simple lines, but with exact length (5000mm, 3150mm, 3950mm etc).where a user could just click and see the lines. Together these lines would make a floor plan for a house. These lines don't have to have thickness, because it will be just a sketch where walls are located. After user has drawn the sketch i would need the program to generate a text file with coordinates of the lines.

View 1 RepliesI cannot get the lines to draw onto the top of the MovieClip box_mc.At this pojnt, my solution is to change the alpha of box_mc to 0. Now I can see my drawings which are under the box_mc but keep within the boundries of the MovieClip.Maybe my thinking is too concrete, but I was trying to get the drawing lines to stay on top of the MovieClip box_mc like it was a small drawing board.I have tried place a reference to the stage in various places and use addChildAt() in order to see f I can change the MovieClip's place in the hierarchy but so far nothing has worked.

View 6 RepliesI am trying to create a flash movie (AS3) that would allow the user to draw using his mouse but straight lines only. The user would click to set the start point of the line then as he moves the mouse around the line would move with the mouse until the user clicks again to set the end point. When the user clicks again a new line is created without deleting the previous one.
