Actionscript 3 :: Trigonometry - Radius Out To The Outer Concentric Circle And Calculate The Position Of That Outer Point?
May 29, 2011
I'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;
var x2:Number;[code].............

I have a datagrid with more than 70 columns (with few fixed). I dont want the scrollbar to appear in datagrid (both horizontal and vertical) but in the parent container which is a VBox (or canvas) instead. This will help to scroll the screen vertically without having to scroll all the way right in datagird to scroll vertically.

I'm using adobe's example.swf to provide inline flash upgrades for users. However, if the example.swf is embedded in an iframe, and the user gets redirected, adobe will redirect them back to the inner iframe page, causing breakage.
Is there any way for this redirect to bring the user back to the outer frame?

I have a swf that I need to attach the flex builder debugger to. I have full access to the source code, and can make a debug build of this swf.
However, this swf is being loaded by a non-debug build of another swf which I don't have source code to, and can't make a debug build with.
I've tried mocking this up with two very simple swfs, and while it works fine when both are debug builds, when the outer swf is a non-debug build, while I can get the debugger to connect, I don't get trace messages, breakpoints don't work, and it seems to lock up the flash app.

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 am no master of Flash. I was wondering if there was a way to tween the radius of a circle to be placed on the circumference of the circle. I want a student to see the radius being transformed to a curve and then placed on the circle. I will be teaching my students the concept of a radian.

I 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.

I am new to Flash & ActionScript 3.0 platform.My issue is: I am loading an image onto the stage dynamically using Loader & URLRequest classes. Whenever I click on existing circle[which gets created when I click on the loaded image, which is of Sprite type], the size of the circle should be increased to some extent(let us assume, basically circle(Sprite)is created with radius=3 when we click on the image, but, when we click on the created circle, it's radius must be increased to 5). It is the requirement.
So, for this to implement, Do we have any property or method to change the Sprite object's size directly?

I need to allow the user to create a circle with a specific radius and colour in a certain frame (lets say frame 2), and then add that circle as a symbol to a different frame (say frame 1). First off, im simply creating a circle.. This is what ive got in frame 2 so far:
(in Frame 2 of the timeline)
Code:
stop();
import flash.display.DisplayObject;
import flash.display.Graphics;
import flash.display.Shape;
[code]....
Ive got this much working, but I dont understand how to convert the output of this function to a symbol usable in another frame..

I 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;
[Code].....
So, can anyone convert these three point curve line to 8 points circle?

I wish to have a function that will take as input a radius value and a magnitude value.
It will return firstly a point (x,y) and also secondly a direction, (vx,vy) which will have a certain magnitude(speed).
The point returned will be a random point within the radius value and the direction will be a a (vx,xy) that moves the point perpendicular to the line segment (x,y) ->(centrepoint).

imagen I have a movieclip (space_mc) w1000Xh1000 px?
inside the space_mc I have 2 movieclips:
- vlak1_mc (w100xh100px, _x:100,_y:100);
- vlak2_mc (w100xh100px, _x:400,_y:400);
ok!?
now i put the space_mc on the stage and scale it to 20% the stage (document properties) are w800xh600
Now i want that the USER clicks on vlak1,2_mc and the space_mc scales to 100% But the clicked vlak(1,2)_mc must have the exact coordinates as in the space_mc?
so if clicked on the vlak1_mc!
the space_mc zooms in to 100% and the _x,_y of the vlak1_mc are x100,y100 on the stage(800x600)?

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.
