We have a flex app that will typically run for long periods of time (could be days or weeks). When I came in this morning I noticed that the app had stopped running and a white exclamation point in a gray circle was in the center of the app. I found a post about it on the Adobe forums, but no one seems to know exactly what the symbol means so I thought I'd reach out to the SO community.[URL]..
View 3 RepliesI want to create circle, and put 8 points on it. So, user can drag each point in order to change it's shape.
Is there any way to do this in flash?
I have some following code:
Ref. - How to draw a continuous curved line from 3 given points at a time
package{import flash.display.Sprite;
import flash.events.MouseEvent;
import flash.geom.Point;

So, can anyone convert these three point curve line to 8 points circle?
I have two circles, an inner circle and an outter circle. I'm trying to find points that reside within the area between the edge of the inner circle and the edge of the outer circle.

I want to calculate the most left and right point of the circle after projected in 2d. (So not 0 and 1 Pi!) The method to create a vector, draw and project to a 2d vector are below. Anyone knows the answer?

View 8 RepliesI have a circle on top of an image that's fading in and out. When I tween the image, a white border appears around the circles on top of the image. This doesn't happen when the circle is below the image layer, and it doesn't happen with a square. Any idea what's going on?
Below is an image of the hairline white border around the black and blue circle.

I have a circle (bounding circle) offset from the centre point of my entity and I'm looking on how to move that circle around the entity as it rotates so that it's always in the same spot of the character.For example,say I have a bounding circle for the front of a car, when the car turns, that bounding circle needs to turn to So I have two points: position which is the position of the entity's centre point and offset which is the offset of the circle from that position. This assumes an angle of 0.
So if my car is facing 0 degrees: position (150, 150) and offset (50, 0) then the bounding circle would be at 200, 150.Now if I rotated the car 90 degrees, the bounding circle should be at position 150, 200.This is what I have now:
var differenceX : Number = _centre.x - _offset.x;
var differenceY : Number = _centre.y - _offset.y;
var rotatedX : Number = differenceX * Math.cos(_angle);[code]........But it's giving me these long ovals and now a perfect circle.
how can me move point arrount circle
just i want the point that you press on it and move it arrount the circle
I want to add point to curve when i click on the curve ,make sure the Original point not change ,eg. a Original point is a control point after add it is Still a control point ，so，may be it is need add two point at the same time

What I'm trying to do is make a dial-type of interface, where you click on a point on the edge of a circle and that point will rotate to another point at the top of the circle. What I can't figure out is how the make "Point B" rotate to "Point A", where "Point A" is always fixed at the top of the circle and "Point B" (and Point C and Point D, etc...) are located along different points on the edge of the circle. I'm using the tween function to rotate, so what I need to figure out is how to get the difference in the rotation between the two points.

var a:Number = 90;//angle of which the semi-circle is facing.. could be a random angle.

I am using the semicircle in BitmapData collision checking with getPixel(), with a moving circle...
It's the beginning of a Monkey Island / Grisworld The Goblin kind of ultra short and simple game. Actually this is the only think I have to figure out.
Actually it already works if you click the x where it's positioned on the screenshot, but it doesn't work other places. And yes I've tried everything, and I'm just nok smart enough to figure this out.
More precisely it's the alternative path, after the arrow collides with the circle, that's causing me problems - since it's going to find it's way to the point clicked on stage.
How to find out different circle's center point of a bitmap?
just like photo above, how can i locate the 2 center points of circles?
i only know using .getColorBoundsRect to get a point, but this only apply to one circle, in fact i wanna get different points according to the bitmap.
How to make a point rotate about the circumference of a circle upon dragging. How do I go about doing it? Is there something to do with the
startDrag(...); ?
From what I have right now, I can move the point but not on the circumference of the circle.
I posted a while back looking for a function to make one movieClip circle around a fixed point. The solution I was given (which has worked perfectly up until now) is:[code]This function is called repeatedly by a Timer (loopTimer) with delay 10.The problem I have hit now though, is that if I want to modify or reverse the speed of rotation at any point it causes a jump in position (because I am setting the x and y values directly, rather than incrementing them e.g. "x = ..." rather than "x += ..."). Can anyone see a way to modify this function so that I can just increment the x/y positions?

View 5 RepliesThis should be a bit of simple geometry: How do I calculate the points to draw the lines in the code below so that it makes a 2D cone or wedge shape?

So let's begin. I want to build a wheel which you can spin, similar to a roulette wheel. You can do this both ways (CW and CCW, this issue causing the bug, actually). The wheel has some acceleration to it too, and I achieve this by measuring the start and final angle of the drag movement, using Math.atan2(dy, dx). The problem is the following: atan2 outputs the following angle scheme, assuming the point relative to which the math is done is in the center of the circle.
atan2 returns a value measured in radians, so I'm using the classic angle*180/Math.PI formula. I've changed this original scheme into the following, using some simple math to shift the angles a bit, to resemble more accurate circle angles (going up to 360 degrees) The problem that I'm facing at the moment is should the user decide he wants to swipe clockwise, and moves through the right point, where 0 turns into 360 or 180 turns into -180, the whole angle difference thing is capsized. It registers a CCW movement (as if the user swiped his mouse all around the circle). So, I'm looking for some ideas as to how I can work around this small issue.
I'm publishing both locally as swf and win projector files, but upon publishing one returns this error: Warning: No libraries were linked as Runtime Shared Libraries (RSLs) because of your publish settings: Windows Projector. Now the exe file works fine but not the swf it provides a white screen with black dots. Don't know why one file is fine (the other project) and only the exe of the other all work, and the swf gives me the white box.
View 6 RepliesI've got two concentric circles with their centers at (centerX,centerY). The inner circle has a radius of 100 and the outer circle has a radius of 400. If take a point on the circumference of the inner circle, I can draw a line from the center to that point. Let's call that point x1,y1). I now want to continue that radius out to the outer concentric circle and calculate the position of that outer point (x2,y2).
I'm adding a 3px 'dot' just to show where x1, y1 is on the screen. (Subquestion: I can't see it...not sure why.)This is what I'm trying:
var x1:Number = 100;
var y1:Number = 50;

how to make a dynamic unfilled and filled circle. that will take input from a slider to dertermine how much of the circle is drawn. I wanted to use this for a preloader. Unlike the author I would like to use it inside of a document class. I am getting 1061: Call to a possibly undefined method createEmptyMovieClip through a reference with static type document. and 1120: Access of undefined property circ1. The second is caused from the first. How would I get this to work in my document class?

I'm developing a game atm, and I need some help on the mathematics/coding of colliding circles (and their change in x/y speed). What i need to know is how to calculate the direction and speed a circle has after colliding with a static (non-moving) circle. I know how to detect a collision between the two, but I'm not sure about the maths I need to give the circle the right speed and direction after the collision
If i do know how far away the two circle-points (in the middle of each) are to each other (in both x and y coords) would it be easy for me to find the new speed and direction of the large circle in the example above? I know that I somehow should use the angles to pretend the circle hits a flat "wall" (as it only hits one point), and then calculate the new speed/direction. My only problem is that I'm not sure how to decide the angle of this flat "wall" and how x and y speeds should change when colliding with a wall that is angled. Does anyone here have any insight, links or tips on how I can du this?
i want to make one circle follow the mouse cursor, inside another circle. Similar to an eye looking at the cursor. Ive attached an example.
