I 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.

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.
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.

I need to use softkeyboard for a flash program developed for windows desktop, and I tried the example given on the following page: [URL] When I test the movie, it gives me a compiler error: 1119: Access of possibly undefined property needsSoftKeyboard through a reference with static type flash.display:Sprite. I noticed that this feature is available to flash players 10.2 or higher, so I updated my CS4, but it still didn't work. Does anybody know what is causing the problem?
View 3 RepliesOur app stopped working, so we had to move through it and locate the source of this bug, bit by bit. Eventually, we discovered the error.
This is how the error is triggered..Create 2 classes like the following:
Quote:
package com.test{
public class World{
}
[code]....
Create a movieclip in the library, check export for AS in frame 1, and assign the class for the MC to "com.test.Boomerang" The error that is displayed then feeds back with :
Quote:
1046: Type was not found or was not a compile-time constant: GraphicsPath.
1046: Type was not found or was not a compile-time constant: IGraphicsData.
"Location" of this error message is blank. This must be one of the most absurd errors ever.
I'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 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.

I'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 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.
I 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}
[code].....
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?
