View 1 RepliesFlash - Drawing Cubic Bezier Curves Programmatically In AS3?
Jul 14, 2010What'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.
ActionScript 3.0 :: Drawing Arcs As Cubic Bezier Curves?
Jun 30, 2011Does 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.

Aug 28, 2009I'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.

View 1 RepliesActionScript 2.0 :: Making Drawn Curves Invisible?
Jun 27, 2006I'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.
ActionScript 2.0 :: Drawing Curves Like Spline Chart?
Nov 25, 2010I 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.

ActionScript 3.0 :: Generating A Good Control Point For Curves?
Dec 15, 2010Im 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}

ActionScript 3.0 :: Possible To Draw Trail With Curves Rather Than Straight Lines
Feb 20, 2012I'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 4 RepliesActionScript 3.0 :: Flash Senocular's Path.as Points In Curves Seem Inaccurate
Aug 22, 2010I'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.
Professional :: Bezier Handles In CS4 For Motion Editing?
Jan 5, 2010I have watched movies of people using the motion editor, I have read books, I have even consulted the cursory help that Adobe offers. Nothing I do generates Bezier handles that i can see, although the motion lines show evidence of bezier-liek modification. What happens seems largely random.
Just as random is the scatter of keyframes. Put a symbol on the stage. Add a motion tween, Move it to a new location: fine, it works. Bend the path, and look in motion editor: suddeenly, dozens fo keyframes. Prod them with the mouse and they distrot, but with no obvios controls. Shift moves them, Cntl deletes them, Alt does god knows what, but evokes the path edit tool from Photoshop.
The documentation on this package is extremely poor. However, self-teaching is impossible as the system is not at all intuitive. If you don't know that you are supposed to toss salt over your left shoulder whilst pushing Alt-Scroll Lock, you don't see what tehbooks describe. But they always leave out that little detail. Adobe's videos are of the same style - too smallto seeproperly, all done at a tremendous pace by a laconic individual with the teaching capabilities of a firing squad.
So: please, ayone, how doo you get the Bezier handles to appear? Where does one find a decent set of documentation? Why does Flash help keep referring to Illustrator?
JavaScript :: Best Method Of Drawing Bezier Line?
Apr 12, 2012I have a conundrum with a design. Imagine the new Facebook timeline with lots of chronological posts attached to it. However instead of a straight line I need to make a randomized curved line with the content placed against it like so:
The complexity comes in because as the user scrolls more posts are loaded (facebook/google images style) so the line could almost be endless.
As far as I can tell my options are:
SVG - poor support in old browsers
Flash layer - embed will be huge and cause performance issues
Canvas - again the canvas will be huge and might cause performance issues
Question: Are there any cross browser gfx libraries which could do this, preferably with support for IE7/8? Or is there a smarter way to do this which I might be overlooking?

Am using only 3 points (start, control1, end) and everything is fine.Now i want to create a bezier curve that passes through a certain point (r1) at t = 0.5 . The problem being that i have my start point, my end point and my point (r1) at t=0.5, and i need to find the control point.

Apr 20, 2011How can I translate bezier pen anchor and control Points into drawing API code? I would like to design my shapes by hand in flash or illustrator, but have the final application draw them on the fly via the drawing api. The only way I can think of is to create a pen tool/drawing application in flash first, and record as you draw.
