I want to make an editor like this site. [URL] If you browse this link you will find "Button. If you press this button you will navigate to a editor to design your layout. After draw a rectangle or circle or line you can resize that or can rotate that. When you finish if press the "you will back to the previous page where your desinged layout display. If you press the "" again then you will navigate the editor with the previously designed layout. I want to make a site like this. I want to use the flash cs4 to make the editor. Anybody knows how to draw a rectangle or circle shape with mouse and how to scale by setting the point and how to rotate by setting the rotation point also by using flash cs4 and as3?.
This 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?
import flash.geom.Point;
//draw circle var mc=new Sprite()[code]...........
UPDATE:I should have mentioned my aim is not to draw a wedge shape, but to draw a line from a random point to the edge of an existing circle.If you're more comfortable with algebra than actionscript,
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.
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?

Trying to do circle circle collisions via math which I'm really having trouble with. One circle (player) just moves from keyboard. The ball reacts to the player. All the code shown is in my players class and I passed in a reference to the ball.
On my enterframe I have:
Code: var xmov1 = xSpeed; var ymov1 = ySpeed; var xmov2 = ballRef.xSpeed; var ymov2 = ballRef.ySpeed;
[code]....
Perhaps I'll go with a box2d equivalent instead of trying out my own physics shenanigans.
Here I what i need is : Start drawing first circle and when first circle is on half way, Start second circle.same way second and third circles. and after completing 3 circles, just gotoAndPlay 2nd Frame .
Let's say i have a simple app where on mouse move user draws a shape. What i am trying to accomplish is to detect if drawn shape is circle so was wondering what would be the best or easier way to do that?
I believe i should do some math based on every drawn point X,Y coordinates but i need a push in right direction from more experienced people around.
How I might use actionscript to place say 100 small MC's on the stage in a circle? I assume I would need some sort of trigonometric function, but my math skills are a bit rusty...
I have a simple three ring animation where the three rings fade in and out.On the stage the rings are a perfect circle, in the publish preview they look fine, but once I publish the SWF, all of the sudden the rings are not perfectly round anymore.
They are almost perfect but right at the top and bottom there is just a small portion which has sort of "flattened out"...
I bought a Flash video tutorial online for Animating and the FIRST step is to create a circle with the circle tool, and the guy does it online, and it fills itself in. I repeat his actions exactly and I cannot get the same result at all. I just get a circle.
I have two MC's, circular in shape. One of the circles is stationary and you can drag the other. I'm trying to get the moveable circle to be able to move around the circumference of the stationary circle, but not overlap. I'm able to detect when they overlap, not using hittest. I just can't figure out how to code it so that the draggable circle can't be moved over the stationary circle.
I have been trying to get this right for hours now it cant be as hard as I am finding it! but basically I have a circle and in that circle is a circle and all I want is for the inner circle to not be able to leave its parent. that's it but I just cant get it to work.
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.
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
I am trying to get a circle to move across from one horizontal point to another. I want this to circle to repeat itself after a certain amount of time but for the previous circle to carry on moving. I also want the circle to appear at different vertical points.
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.
I am trying to rotate some points around the center of the circle(0,0), however I'm getting weird values from the output. I've commented the problem code..
Code: var r:Number = 10;//radius var y:Number; var x:Number; var a:Number = 90;//angle of which the semi-circle is facing.. could be a random angle. var ax:Number;//rotated points [Code] .....
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.
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.
