This draws almost perfect circle:
ActionScript Code:
var _angle:Number = 0;
var _speed:Number = .1;
var _radius:Number = 100;
[code]...
but...... if I wanted the circle to be drawn faster and change _speed to lets say .7 the circle becomes a polygon. How to get the circle to be drawn fast so it looks like a circle?
I draw a rectangle i should see a little bold circle to indicate a perfect rectangle, I seemed to lost mine, can somebody please tell me how to get it back!
View 2 Repliesany techniques they use to draw a perfect half circle?
I've seen the curveTo() method, and I cannot seem to make it come out with anywhere nearly good enough results. It always looks like half of a skewed ellipse.
I don't *want* to use a mask -- since there will be other drawings on this same Sprite that I do not want masked.
To be even more picky -- I don't *want* to create the half circle in another Sprite and add that to my original drawing.
I have tried to draw a circle using drawing API curveTo function. But the result is not a perfect circle. Flash documents also suggest this method. Check this link >> This is the code I have used to make a circle of radius R and the registration point of circle movie clip is at the center.

I'm working on a project for a client, they want a simple drawing api which requests the user to draw a circle, or a shape on screen. The circle is then analyzed and a Score/Percentage of correction is returned. The drawing I have covered, how to assess the drawn circle against a perfect circle?
My first idea was to put invisible trigger points around the circumference of the shape and check for hit tests when the user is drawing. Another would be to track the dimensions of the left, right, top and bottom most bounding box and then find the radius, or something to that effect.
I`m working on a app that you can draw lines.....like circles, rectangles... my problem is when a user draw a circle for example....i wanna be able to paint (change color) inside of this circle. I`ve tried working on Shapes with cacheAsBitmap = true and Bitmaps with BitmapData but it doesn`t seens to work.

View 2 Repliesi have the custom flv player which reads an XmL and draws circles on Flv video. Postion and time is specified in the XML. I did calculation with as3 getTimer() function. It works fine, no matter how long u pause and then play again. Circles are shown at right time.Now i have two problems
1- How getTimer can be reset?? it is required when user is allowed to play another swf..
2- Is there any other way besides getTimer calculation. I am not using Timer Class as it is Dependant on Frame-Script Execution time and may yield wrong result so this is not as accurate as getTimer() function.
3- As i am using Custom Slider , so i have to do calculations each time when user click or drag slider w.r.t getTimer() function and then subtracts seconds and all that. but again it goes very hard when user plays another swf as my calculations are based on getTimer() Funtion.
I have a requirement wherien a semi circle has to be drawn. The circle radius can be chosen/varied by the user. How can i do it dynamicaly using action script.
View 1 RepliesI want to draw a circle on the scrren of a random x,y position and a random radius. Then, I would like to draw a line that starts at the center of the circle and ends at the spot where the circle ends, at its perimeter. All I have been capable of doing by myself was creating that circle and set the drawing position with the moveTo function to its center, but I don't know how to calculate the length of the radius, so I have the coordinates for the lineTo function.

This code is to be the animation that shows how much time is left before a specific event fires off. I am struggling with the Math though.

I have a hitTest on an enterFrame event that adds a movieClip.I then want the movie clip to be on a timer that changes it to another movieClip.As you can imagine, there is a conflict because the hitTest always finds the original Mc an so over-rides the timer.I know this is a logic problem but I cant seem to figure it out.I am pretty sure I am thinking about this the wrong way.here is some of the code:
//this is the hitTest
this.addEventListener(Event.ENTER_FRAME,leftPillarHit);
function leftPillarHit(ev:Event):void {

In the move function below, I'm attempting to have move return false, when it becomes true I want to delete this on enterframe event. In essence when the clips come to rest and the function is no longer needed delete the function call.
Code:
//Variable to store number of Clips desired
clipCount = 6;
xArray = new Array(179.1, 249.1, 321.0, 179.1, 249.1, 321.0);
yArray = new Array(145.0, 144.0, 145.0, 206.0, 205.0, 204.0);

I am trying to figure out how to get an enterframe event listener to stop. I created a simple example below, where a line spins around on stage until the user clicks on it. When they click on it, the user should be jumped to frame 2.
Code:
stop();
stage.addEventListener(Event.ENTER_FRAME,rotateIt);
line_mc.addEventListener(MouseEvent.MOUSE_DOWN,goSomewhere);
[code].....
However, when I run that code, I get the following error:
at test_fla::MainTimeline/rotateIt()
TypeError: Error #1009: Cannot access a property or method of a null object reference.
Which tells me that the event listener is not being removed. I also tried putting the removeEventListener code on frame 2, which didn't work either.
i have linked a movie clipe and creating multiple copies of it through attachMovie().i want to used this enterframe event to change the alpha of all my movie clips from 100 to 0 and viceversa when i drag and drop the movie clip

I'm using greensocks MP3Loader to play IntroMp3. I want to dispatch a custom event when the value of the MP3Loader.soundTime property is 3 (3seconds). I've done it with an enter frame event. the problem is that it dispatches the event more then one time. what is the better way to check that the MP3Loader.soundTime property is == to 3 and dispatch my event only one time?

I need to make a circle with a brush tool so that it looks like a child draws it. If I make a dot with the brush tool on the first frame and a circle on the 15th frame and then create shape tween between those frames it looks stupid, like the circle grows itself. Is there any possibility of making such a thing except for drawing it per frame?
