I have an array that contains the points for drawing multiple hills. When I just draw straight lines it works fine, but that is unnatural so I want to make the top/bottom parts of a hill curved.

What's the best way to draw cubic bezier curves programmatically in AS3? The Graphics class only seems to support quadratic curves. I want to be able to do something like:
var startPoint:Point = new Point(0, 0);
var endPoint:Point = new Point(5, 5);
var control1:Point = new Point(5, 0);
var control2:Point = new Point(0, 5);
var myBezier:Sprite = getBezier(startPoint, control1, control2, endPoint);
For a performance target, I'm planning on having ~50 of these on the stage at once.
I have five dots(MovieClips) in my stage. I want to draw a curve which should touch all the five dots. The x position of dots are incremented by 50 px and y position is random.I can do this using lineTo. But it has not got any curve effect.
Here is the code using lineTo
Code:
_root.createEmptyMovieClip("circle",1);
with (_root.circle) {
clear();
[code]...
I tried curveTo to achieve this. But it is not working.
Does anyone know of any code examples of drawing arcs as cubic bezier curves? (Yes cubic, not quadratic.) I have 2 end points, a center point, and a radius. I suppose I would also need to define a direction as well, since it could go around clockwise or counter-clockwise.
View 0 RepliesHi all.
I have a main swf which I load in a few different external swf. For each of the external swf I have resize handlers which make sure my loaded swf are position in the correct place when window is resized. It works almost perfect.. but let say 1 out of 4 times the resize handler stops and nothing happens. Why does it sometimes work only?
I know I should not have function within a function but in this case I do not know how to do it in any other way?!

View 1 RepliesI've been working on simple animation for a client, which you can see __here__.I have a few issues with performance. I have popped a fps counter at the top left and it seems to only run at around 30 fps on my laptop, I need it up to 60 though.
i was just wondering if anyone had any tips about getting the best performance from flash.I have used Shape instead of Sprite on the curves, which gave a slight improvement. Surprisingly I didnt notice any change in performance when I dont use the blur filter on the curves, which was odd to me.
My Flash application receives B-spline data from an external application but the Flash drawing API only allows quadratic bezier curves using the Graphics#curveTo() method.Is it possible to convert a B-spline into a series of curveTo() calls?
View 1 RepliesI was doing something with GraphicsPath, unlucky, I couldn't solve cubic curves. I found there is a method curveTo in Graphics, but it only supports quad curves.
View 4 RepliesI'm working with Senocular's Path.as file and I notice that the points that it outputs on curves are not very accurate. [URL] The code has a variable for curve accuracy in there and I have tried changing it but if I set it to 1 or to 500 it doesn't effect the placement of objects on the curve.
Basically what I am doing is putting beads on a necklace and pushing them through a curve. Kinda like in the game Zuma. However when I set the positions of the beads to go up incrementally there seems to be a slight burst of speed on the curves, that speeds up at the ends and slows in the middle a little. I was wondering if anyone had any pointers on how to make the curves more accurate with this script? It is a hell of a good script by the way I'm sure I'm just stupid and not seeing something.
Just installed Flash CS4 and the first thing i realized was:When I break apart text the curves straightens in some places.Is there a setting i need to set up for this not to happen?Didn't have any problems in CS3.

View 4 RepliesI've made a drawn menu with curves in my root. This menu loads dynamically swf into an empty container mc. Within some of these swfs, there are full page image galleries. However, the drawn curves seem to stick on top of these swf: I can still see them although the rest of the content is invisible. Now I want to make those curves also invisible...
Code:
//API AND LINES//
box2.lineStyle (1, 0xff00ff,0);
box2.beginFill(0xCCCCCC,0);
box2.moveTo(0,0);
[code]....
Now I want to realise a function in an externally loaded swf that makes these lines/curves invisible. i was thinking myself of something like
Code:
btImages.onPress = function (){
_root.line.lineStyle(0.5,0xCCCCCC,0);
gotoAndStop (3);
}
But unfortunately thsi doesnt work.
I have to dynamically animate some bezier curves that have to look like this. Here is the archive of my approach and I'm not sure is the best one. I mean it kind of eats the whole processor.
View 1 RepliesI am looking to trace mouse movement and convert to curves then have a spritefollow the traced path - similar to the iphone app Flight Control.
View 2 RepliesIm trying to animate a particle in a way that it just curves. If your familiar with beziers (im not) then you know that there is a start point, a control point and an end point.I am finding it difficult to dynamically generate a good control point.So a line starts at x:0, y:0and ends at x:100, y:0I know just from basic mathematics that i could find out the middle point:x:50, y:0Then i could just randomly specify a y value of say... 10. So my curve now looks something like this:
starts at {x:0, y:0}
control point at {x:50, y:10}
ends at {x:100, y:0}

I've had a look at the Graphics class in AS3 and come up with a dynamic mouse trail. It works, but it's pretty rough and ready. I wonder if anyone could give it a once-over and see if there is a more elegant and efficient way to accomplish this?[code]is it possible to draw the trail with curves rather than straight lines, so that the curves mimic the path the trail would take to smooth out the jagged lines drawn when the cursor is moving quickly?
View 2 RepliesOnmy stage I have a MC, and when I click it a random MC from the Library should appear and move around randomly.

how to make the random MCs appear from the library. And should I put the random moving script on each of my ten MC?
Im animating an around in 3d space with papervision and Id like to make the curves of the animation nice and smooth, if I put random values into the xyz and bezier values the turns are quite weird and erratic. Does anyone know of a way I can animate something around in smooth curves, but not have to create specific values for the tween?

Basically 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 have a movie clip (with instance name rectangle_mc) on the stage. Within this movie clip there are two separation animations on the timeline. The ROLL_OVER animation starts on frame "over" and the MOUSE_OUT animation starts on frame "off." If I roll over the movie clip, the initial animation plays, and when I mouse out the other animation plays to restore it to it's initial state. However, once the rollover animation has played once, it will not play again when I roll over it again, but for some reason the MOUSE_OUT plays every time.

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?

// This code is for drawing the lines on the page
//1.
var drawingLine:MovieClip = new MovieClip();

View 2 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.

import flash.display.DisplayObject;
import flash.display.Graphics;

I am workijg on creating an animaton it is 300 mb in file size and i am running windows 7. i have also tryed working on windows xp and the same problem happens.
what happens is that i could be drawing or copying a layer that i need to work with and flash will think for a little bit and then crash says that an unexpected error has occured and all i get is an error excption. i am running CS4 on windows 7 with 5gb of ram.
In the car game i am working on, I now got a point system set up so the car hits different items and the points rise but i want the items to appear in random places instead of 1 place only
[URL].. Game link so far - but not published the point system yet. don't provide to straght forward advice such as "copy this code (code here)" etc
Please can you provide the code i need. The MC car is called 'car 1', the MC items have different names such as g1, t1, pt1, pb1 and shine. Please tell me where i need to place the codes in the firstplace.Whether i need to click the car or the item and paste the code in frame 1 etc?
Over all, all layers have a total of 3 frames. 1 key frame i believe and the other two are normal frames.
