I'm drawing a 3D pie chart that is calculated with in 3D vectors, projected to 2D vectors and then drawn on a Graphics object. 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?

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.
View 1 RepliesI 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.

I am looking for a way to find a vector if I know one point and 1 angle. Like I have A(x, y) and a vector starting from A(x, y) with an angle. I would like to know the position on a point X (x, y) that can be anywhere on that vector. I only know the coordinates of A and the angle. Possible?? I guess it has to be a function...

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.
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:

Is there a ready Component on the web.
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]..

I'm trying to run ASDoc on just one of my classes, but I keep getting the following:
ActionScript Code:
Error: Cannot find JRE.

I've read up on the issue and I tried setting up the JAVA_HOME environment variable to point to ..AdobeFlex Builder 3jre folder but it's not working at all. Is there a compatibility issue or is something else going wrong?

I have a rectangle of any arbitrary width and height. I know X,Y, width, and height. How do I solve the upper right hand coordinates when the rectangle is rotated N degrees? I realized if it were axis aligned I would simply solve for (x,y+width). Unforunatly this doesn't hold true when I apply a transform matrix on the rectangle to rotate it around its center.

View 4 RepliesI know some basic trig. but how do i find an angle from an anchor point and a moving point?
adjecent = _root.anchor._x-_root._xmouse;
opposite = _root.anchor._y-_root._ymouse;
hypotenuse = ((adjacent ^ 2)+(opposite ^ 2)) ^ 0.5;
im been trying to make a stationary movie clip do a jump move to the top, slowing down, and then comming back down (like a ball being thrown vertically up) within a given number of frames, ie 10 frames. Also i would want to add a horizontal vector quantity whereby if a key is pressed (ie left) then it would move horizontally left while still in jump mode. Does an actionscript like this exist?? if so can someone please post it here?
View 2 Repliesi don't know how to say that in technical terms. and i think this is the reason to why i cant get good answer from Google.i have xampp on my local winxp machine. i use it for developing websites locally then upload these files to my clients shared hosting accounts.
the problem that in 2 years i have always found differences between how xampp works and how the web server work.some code work locally but dont remotely and the opposite. also flash behave differently on xampp than the remote web server.is there is a way i can get the server configuration and use it with xampp like get the server php.ini and use it with xampp?
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
View 3 RepliesWhat 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...
Okay without putting a million boxes around the circle, which i found laggs out my game alot. How can i use some sort of code to find all the coordinates inside a circle.
View 2 RepliesI got a working broad phase and collision detection is fast enough.Now my collision response is working, but slow. I have trace(using getTimer()) through the whole resolving method, and I found the slow spot is where I get the collision point and normal vector.
Right now, I test each point on each shape against each line on the other shape. This works nice on triangles, but other shapes, it much to slow.I would think that using SAT(seperating axis therom) would have a way to get this when checking collisions, but I cant seem to get it.I need a fast way to get the collision point and normal vector.(Right now, it takes about 3 milliseconds per collison on a rectangle with 4 points and 4 lines)
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 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

From what I have right now, I can move the point but not on the circumference of the circle.
Vector Scaling Object Without Affecting the Original Point
View 1 RepliesI 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 1 RepliesI need to know the best method to find an item inside a list (Vector, Array, Dictionary, whatever is faster) of complex type (extensions of Objects and Sprites).I've used "Needle in Haystack" method, but it seems that it isn't fast enough.
E.g.Suppose that I have a collection of Sprites (a pool, in fact).Each sprite will be added to the stage and perform some action. After that, it will die.I don't want to pay the cost to dispose it (garbage collect) and create another (new) one every time so I'll keep the dead sprites in a collection.
Sometimes times I'll call a method that will add a sprite to the stage.This sprite can be a old one, if it is already dead, or a new one, if the pool don't have any free sprite.
One of the scenarios that pushed me to this question was a Particle System.A "head" particle leaving a "trail" of particles every frame and exploding into a flashy multitude of particles... Every frame...Some times this counts up to 50.000 PNGs with motion, rotation, alpha, event dispatching, scale, etc...But, this is JUST ONE scenario...At the moment I'm trying to use a Object Pool with a Linked List...Hopes that it will be faster that running a whole Array/Vector or create new instances every frame an let them dye with Garbage Collection.
