ActionScript 3.0 :: How To Easing Movement Along A Circle
Nov 15, 2010
I learned easing movement,it can use following code:vx=(targetX-sprite.x)*easing;vy=(targetY-sprite.y)*easing;sprite.x+=vx;sprite.y+=vy;
I know above code can run well along a line. Now I have a sprite and put it on the border of a circle,like follows:angle=30*Math.PI/180;sprite.x=centerX+Math.cos(angle)*radius;sprite.y=centerY+Math.sin(angle)*radius;
Now I make angle equals 120 degree,like follows:angle=120*Math.PI/180;I want to know how to make the sprite from 30 degree to 120 along the circle border by using easing movement? I don't know how to realize above model, I worked it for a whole day,but it failed. Which mathematic formula can I use? Source code is better.

im trying to create this custom menu a bit more efficiently. As written, it operates fine glitch free. However, id like to incorporate some easing into the movement of each movie clip.
[code]...
how to incorporate tween classes and then easing?

how to use AS to create movement with easing in AND out?
I was trying to get an mc spin according to the speed of the mouse. So when I move my mouse quickly, the object starts spinning faster and faster, but after reaching it's maximum speed, it slows down again.

i've figured out how to move objects with actionscript but am having trouble pushing it a bit further. i'd like to: a) ease in and out with actionscript and b) have the object move to a certain distance, then move back.

skyline movie clip to move randomly along it's x axis whenever a mouse event happens.I can get it to ease in on a mouse event.The only code I've come across that seems to point me in the right direction is easingvar skyline:Tween=new Tween(skyline_mc,"x", Regular.easeInOut, 100,107,3,true);How do I get it to easeinout again to a random position on the x axis?.

I am looking for the functionality as seen on [URL] in the Flash header. Specifically...
1.) First of all, the blurred background moves horizontally when the mouse moves over it, then gradually slows to a stop when the mouse leaves the area. What's that actionscript?
2.) Second, the face/headshots (give them a second to move into the header from the left side) that move toward the mouse when the mouse is hovering over the background and then ease back to position when the mouse leaves the background area.

I'd like to add a movement easing script to a movie clip that rotates toward the mouse constantly. Here's the script on a controller movie clip (I know that's old-fashioned):
Code:
//variables are angle, x, y, and r
//x and y are the mouse's relative coordinates (legs)
//angle is the rotation of the gun (hypotenuse angle)
[Code]....
I'd like that line <<_parent.turret._rotation = (this.angle*-1);>> to instead smooth the movement (That is, go half the distance each frame) . . . but upon adding the traditional code (which can also be found somewhere on kirupa), when I cross the mouse from, say 359 degrees to 1 degree, the accursed thing spins the opposite direction. I understand why this happens, but have no thoughts as to how to fix it. It has baffled me for some time.
I'll attach the .fla in case the above is too cryptic, but keep in mind that there are some other features since added, like firing bullets and such. Ignore the actions concerning these; the only important code is on an empty mC called script. It's inside the motoGun mC, at 0x0.

I'm trying to develop an infinite menu (horizontal scroller) for a Portfolio. It works but not properly the way it should. After few loops the images get out of sync I don't know why. And if possible can you also help to add some easing to the movement? What I did was, I add to instances of the menu one called menu and another called menu1. Than add the following code to the timeline: import flash.events.Event;
[Code]....

I'm trying to make a dummy from a circular menu that reacts (rotate) to mouse movement, I uploaded a fla example, different colors, size, etc, but essentially the same in function; but for now I'm freezed how to do somethings, I'm not a programer or actionscripter, but I want to learn.Currently using CS3 and AS2, downloading the FLA example may help. in the "fla", you will see a circle who rotates versus mouse movement (I would like to make a delay rotation for a smooth feelling when mouse is moving, those like "_x += (_xmouse/5)" but with rotation. Other thing I would like to do,is... that the movement stops progressively a few degrees before the mouse reach de cian angles(a1,a2), and then, the circles doesn't move if the mouse is moving under those angles, like a... an inactive area(U1), and if it could work with instances.

I have a big circle with buildings all around the edge. There are two buttons that should control it. One to rotate the circle left, and one to rotate the circle right. I'd like each click of a button to rotate the circle and have it stop on a building, which then would activate an animation of the building.

I have been working on a horizontal AS3 draggable menu for some time now and i am almost there with it. I am basically trying to replicate the menu at [url]...
So far i have got everything to work apart from the easing movement when the menu is dragged. The menu is quite simple, it is made up of a container mc.Inside this container there are 6 buttons which fill the dimensions of the container.The container itself is bigger than the stage and the user must click and drag the menu horizontally to see the rest of the menu.This is working. However, i am still after an easing effect when the menu is being dragged as it stops dead (because it is using the startDrag and stopDrag commands).how to implement an easing effect on the dragging of this menu i would be so grateful as i cannot manage to do it! (perhaps using tweenlite or tweenmax if its easier, or by using simple physics - I have attached a zip file that contains a compiled SWF and a CS4 FLA file.This is the AS3 i have so far:
Code:
stop();
import com.greensock.*;
import com.greensock.easing.*;
import flash.events.MouseEvent;[code].........

I've built a code to cyclically move a scene on the bottom of my stage; I've done this to make a slowing-and-stop-easing effect at anytime the command will arrive. The entire scene mc is _x long something like 6000 px. The whole code goes in this way:
1) importing on the stage (with attachMovie) a mc with this code inside:
onClipEvent(enterFrame) {
_parent._parent.fondo_mc._x -= countermovement;
if (_parent._parent.fondo_mc._x <= -5800) {[code].....
The code goes right, but I need to improve it.Now there is just a variable, I tought to use two vars to implement the whole code in a setInterval, but maybe it's unuseful, and actually I can't use it in the right way.
Second issue: actually when slowAndStop function is called the scene slow too fast, if I take it to 15 it slow better but the scene is running too fast...
The best would be that the scene slow down and stop following: A) a temporal variable (and I can try to implement it with setInterval, that for istance is a cycle)
B) an indipendent moving variable, so that on one side I set the speed, on the other side I set the slow-and-stop in a matter of time with countermovement.I also tried to use a second variable:
var counter:Number = 15;
// set the _x increment
var countermovement:Number = counter/2;
but the scene slow and goes backward a bit

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'm familiar with how to ease something in using motion math. Easing out would not be that bad either. But how would I script something easing in half way, then easing out the second half? It would start slow, gradually move faster, then slow to a stop at the end. - almost like a sine wave I guess?

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?

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.

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.
