ActionScript 3.0 :: Moving Movieclips Using Trigonometry?
Apr 16, 2011
I have this game where a movieclip moves towards the mouse point by finding the difference and dividing by its "speed". This isn't very good though because different users will have different cursor speeds. What I really need is a method that finds the angle between the two points then uses that angle and a "speed" to calculate the next position of the moving movieclip.Here's something along the lines of what I am looking for but it doesn't quite work?The function runs and everything. All that works, it's just the maths that isn't right.Something needs changing with the maths.
ActionScript Code:
function moveCircle(e:Event):void
{

Basically I have two movie clips. I know the x diff and the y diff, now how do I find the angle at which the movie clips are at?
Code:
v MC 2
/|

/ | < y diff

MC 1 > /__|

From what I have gathered, _rotation uses radians?Basically, my initial goal was to make a movieclip rotate towards the mouse. I'm not very good at trigonometry.Using the help files I found atan2 which seemed to be what I needed. A little fiddling got me to this code:
var xDist:Number;
var yDist:Number;
var angle:Number;
onMouseMove = function () {
[code].....
However,the _rotation is opposite what is expected. This is not a problem as I can just flip the movieclip. But really what im here to ask is, please ecplain this code for me? I don't correctly understand how atan2 works.. and why it needs to be *60.Basically: How to get a movieclip to rotate towards the mouse.. and why does the code work, I want to learn trigonometry.

i know how to check the angle between my object and the mouse, but i dont know how to make it rotate slowly to it...
i tried this codes:
Code:

I know how to move movieclips from one spot to another with a click of a button. I want to go further. After a few seconds, that movieclip will move again to another spot. So, with one click, my movieclip will move to one spot, and then after a few seconds will move to another spot.

why these two movieclips are moving at different speeds? I would like them to be moving at the same speed (while increasing xspeed every second).
actionscript 2, flash mx.
Code:
var xspeed = 1;
countDown = function () {

Is there someone who is good at trigonometry? I have two points punkt1 and punkt2 and a line that is drawn between them. Both points is dragable. I want the line to continue after the points in both directions and with the same steep. I have counted the steep between point1 and point2 and tried to continue to drag to a point with the same steep, but it doesnt succed.

I'm currently making a game in which movie clips move across the screen and you have to shoot at them to make them disappear and gain points but I am having problems with the code. I have been able to get the movie clips to disappear but when instead of points appearing in the Dynamic text box, i get the letters 'NaN'.
This is the code I am using at the moment:
this.onRelease = function():Void {
this.unloadMovie();
_root.panda++;
};
(panda is the var name of the dynamic text box).

I have a difficult question and I have searched all over but cant find a solution.I have 3 movieclips:a) circle, filled in blue, black outlineb) circle, half filled in blue, black outlinec) circle, no fill, black outlineI have one instance of a movieclip moving randomly about the stage and want it to fade between a) b) and c) (based on a user defined input array eg circleArray[a, b, b, a, c, b, a] - if that makes sense?)The only way I am thinking is to have a movieclip that contains each of the 3 movieclips and then fades each to alpha 0 with a black outline at the bottom layer. And then referencing each faded movieclip with a label?

I'm making an image gallery and I want to have a bunch of thumbnails on the bottom of the screen that smoothly slide from side to side when the mouse moves.
I'm working with a custom class for the container (Tiles) and a custom class for the thumbnails (ImageIcon).
I have a ComboBox which allows users to to choose a gallery. When the user chooses a gallery, the following code is run and the thumbnails should reload. The problem here is that the icons appear on top of each other instead of side by side, also switching categories should remove the old one (see the first for loop), but it does not. Also, the Icons are not animating properly. The animation code is below as well. Right now, only one of the icons will move. The icons should move in order from side to side, stopping when the last few icons hit the edge of the screen, so that they don't get "lost" somewhere off to the side.
Gallery Loader Code:
public function loadCategory(xml:XML = null){
if(xml != null){
dp = new DataProvider(xml);

Is there anyway that I can make this script so my MC moves in a curling motion?
PHP Code:
// Gives them vars
onClipEvent (load) {
this._x = 275;
this._y = 200;
this._xscale = 0;
this._yscale = 0;
[Code] .....
This script makes a spot move from the center out and scales a little. I want same movement but with a curling motion or a slight curve...

Click on a thumbnail and the corresponding image is preloaded BEFORE scaling and moving smoothly from the thumbnail position to a target position. (the thumbnail is actually the container for the loaded image, and therefore also moves to the target) I have got everything to work, except that the thumbnail moves whilst the image is still loading. This problem defeats the purpose of the gallery, and I'm starting to get blurry vision now!
I hope I have made everything clear, but since this is quite difficult to explain, I have attached the fla and images. *You will need to simulate download in flash for the current preloader to work. P.s. much of the script was (heavily) adapted from an fla I found somewhere, in which the images are arranged into a circle.

I'm making a screensaver where random characters in different positions and sizes walk/run across the screen. It seemed simple enough, and everything appears as they should. However, none of the Movieclips move forward on the stage. Here's the code on the first frame of the timeline, bolded lines are points of possible concern:
Code:
import flash.utils.*;
var timer:Timer=new Timer(5555);
timer.addEventListener(TimerEvent.TIMER, makeCharacter);
timer.start();
function makeCharacter(e:TimerEvent):void {
[Code] .....
And here's the code found in each movieclip:
var isOnStage:Boolean = true;
With no errors to go off of, I'm unsure how to proceed.

I am using the following code to simulate a volume control bar filling on vol+ and unfilling on vol-. The dragger is a mask that causes the fill to appear and disappear when the mouse is pressed and dragged on the volume controller. It works well, but I would like to add a "switch" that moves at the same time and in the same location as the fill, but on top of it... I created the movieClip for the switch and tried all kinds of variations to the following code with its instance in the code, but cant seem to get it working... below is the code which works with just the mask filling / unfilling.
this.ratio = 0;dragger.onPress = function() {this.startDrag(true, 0, 0, line._width, 0);
this.onEnterFrame = function() {
ratio = Math.round(this._x*100/line._width);
_root.volume = ratio; }; };
dragger.onRelease = dragger.onRelease=stopDrag;

I want to move a mc with actionscript, along a path, and this movement to last about half or so of a second (just like tweening in the timeline with frames and all). How can i do this?

I want the final result to be a stage with a certain number of circle MC's moving around. I have made the circle MC, and added the AS so that it will start at a random point with a random color, then start moving around randomly. I want to make it so that In the beginning the document will duplicate the movie clip x amount of times, using a for loop. I want to then have all the new circles move around, and when two circles hit each other, they will dissappear, using the removeclip function. You can only use this on duplicated movieclips though, so how would i make all the circles duplicated? Is there a way to duplicate the original movieclip x amount of times then delete it? Or is there a way to remove the original after it is in a collision? Also I don't know how to do the collision detection. I am thinking of using a hittest, but would I just do it with a for loop? Is there a way so that if an MC hits any other MC?

I am working on a website where I have some movieclips on the stage scattered. Some overlapping each other. Now when I move my mouse over any movieclip, I want the movieclips around it to move away from it and when I rollout they should get back in place. An example of this can bee seen on [URL].

count++;

Everthing works fine. But it is shaking so that it was not looking good.How do I achieve smooth movement?

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].............

im currently making an "AS3 beat em up" ala streets of rage or double dragon.Currently i have my character moving and a few animations done and i am trying to figure out how to make attacks work.I have some "basic" animation for his attack, but im not sure how to get it to work correctley.What happens is, if you press control (the attack button) whilst the character is walking he just keeps moving and is stopped on the attack frame.I want the character to stop moving if the attack is pressed and once it is released start moving again.
hero.gotoAndStop('still');

I m trying to make sense of how to load a swf into a parent MovieClip and allow them to communicate.I ve attached two zip files � one which works fine and the other doesn�t. Unfortunately (for me), the one which doesn�t work is closer to my current project.I need to load movieclips into the parent movieclip. The parent movieclip has controls which rely on values parsed from the child movieclip.In the parent movieclips I wait until the loading is complete and so the values should be passed. However, the values aren�t passed unless I use a button (or timer), to pass the values (see the working exampes).The code which doesn�t work is:
Parent movieclip:

stop();
var myLoader:Loader = new Loader();[code].............

Looking for a way to stop all movieclips both are the stage and that are children of the ones on the stage.
I toyed with looping thru stage's children so I can first target clips on the stage. But I am getting error.
for (var i:int = 0; i < this.numChildren; i++) if (this.getChildAt(i) is MovieClip)
{
this.getChildAt(i).stop
}}

Printing an MC is easy enough. But I am having trouble printing an MC which has multiple MCs inside of it. They just don't get printed.
