ActionScript 3.0 :: Find Distance Between 2 Movie Clips?
Jun 28, 2011
How does Flash use Math.sqrt to get the distance between 2 movieclips? In the example the only givens are 2 points along a triangle:
function getDistance(x1:Number,y1:Number,x2:Number,y2:Numbe r):Number {
var dx:Number=x1-x2;
var dy:Number=y1-y2;
return Math.sqrt(dx*dx+dy*dy);
}
dx is the difference between the x coordinates of 2 points/2 mc's
dy is the difference between the y coordinates of the same 2 points
the Math.sqrt is the Pythagorean theorum
If the Pythagorean theorum is a^2+b^2=c^2 for the sides of a triangle how do 2 points achieve the same result if the lengths of the sides aren't given?

I have two movie clips. One is simply on the screen, meaning it can be referred to as _root.movieclip1. The other is within another movie clip, like _root.movieclip2.movieclip3. How do I calculate the distance between the movieclips 1 and 3? The third's coordinates are shown not as they would be on stage, but from inside the second movie clip. I'm using Macromedia Flash Professional 8.

i am working on a game called "virus". you click somewhere on the screen and the virus goes to where you click. you have to dodge random moving white blood cells, and if you hit them you lose. everything is working. except for one thing. scoring.
i have made a movieclip with a dynamic textbox in (score), and in the movie clip there is a section where the number in the score textbox goes up really quickly, a section where is goes up medium, and a section where it goes up slowly. i want to make it so that when you get closer to the center of the movie, for the score to go up quicly, and slower as you get further out. i have tried hittest with movie clips in the centre of the stage, but it doesnt seem to work.

I'm using Flash CS 5. When I look at FLA project tree, I see Use Count column next to a movie clip. How do I find where this movie clip is used?
I'm hoping there is a 'Find usages' or 'Find references' feature since Flash CS knows about usage of a movie clip.

in my program the user can create multible movie clips so i stored them in an array. now the problem is i need to find the ._x of all of them. so i have tried to create a for loop that will go through at a certain amount of times (pending on the number of created movie clips)
Code:
for(z=1;z<=_root.howmany;z++)
trace(array_name[z]._x);
}
it doesn't work?
the array is storing the string of the movie clip
(like; _root.moive1, _root.mave2,etc)
but when i try to access it, it doesn't work? what am i doign wrong and/or what should i do?

I have the following code...
[Code]....
The point of this code is to be able to search through previously duplicated movie clips to find the one that I am trying to access.... it doesn't seem to be working even though I have a similar routine that does seem to work. Anyone know of a better way to access/traverse the available movie clips to find the one I want?

I am rotating an object with TweenLite, however instead of a set duration I want the duration to be based upon the distance of rotation where 180 degrees = 3 seconds 90 = 1.5 and so on. Here is my attempt to find the distance of rotation:
var time:Number = Math.abs(Math.atan2(Math.sin(angle-wheelObj.rotation),Math.cos(angle-wheelObj.rotation));
TweenLite.to(wheelObj, time, {shortRotation:{rotation:angle}, ease:Expo.easeOut, onComplete:rotateWheel, onCompleteParams:[target]});
TweenLite.to(carObj, time, {shortRotation:{rotation:angle}, ease:Expo.easeOut});
This just isn't working, time is sometimes huge when the rotation is small and sometimes tiny when it is big, so does anyone know a better way to do this?

This code calculates the distance between 2 points by using distance formula, Math.sqrt ( (x1 - x2)^2 + (y1 - y2) ^2). My first point has mmx and mmy coordination and second one has ox and oy coordination. My question is simple, is there any FASTER way for calculate this?

How could I find the distance between a given point and a drawn line? I was thinking about using the point-slope formula to draw a perpendicular line between the point and the line and measuring it as the distance, but I'm not quite sure how to do this in as3.

I created a movie where I have a circle in the middle and a line drawing from the center out when the mouse moves. I want to calculate the distance from the mouse position to the middle of the circle. What I am going to do is have a sound playing from the center of the ball..The closer you get the louder the sound gets and the further away from the middle the quieter it gets. You can download my fla to see what I have so far.

Is there a way to find the radial distance using the zipcode? My task is to search the all the users residing with in a specified distance. I know the zipcodes of the users. Eg, users between 25 miles from the current location. I have other search categories, for which i am using mysql queries. I am unable to figure anything out for the distance issue.
My backend is in php
and frontend in Flex.
The best option for me would be something like that of www.zip-codes.com/zip-code-radius-finder.asp. ie, if I should be able to get all the zip-codes available in the specified radial distance. So i can compare this zip-codes to the users zip-codes in my database. And select the ones with a match.

So, right now when I want to find the distance between two points, I go: dist = Math.sqrt((this_x-that_x)*(this_x-that_x)+(this_y-that_y)*(this_y-that_y)) BLECH! I don't want to do that every time. So I want to make a nice little function that I can apply to an object. Problem is, I don't know how to do this. Is it possible to end up with something as easy as: Math.dist(thisclipname, thatclipname)? How do you guys set up functions that do bulky math and return nice clean numbers?

I'd like to control a movie clips current frame by another movie clips action script.I realise the following controls the outside (root) frame time line:
on(release){
_root.gotoAndStop(1);
}
but I'm not sure how to apply that to my other movie clip. I'm guessing it would be something like this:
on(release){
_*movie_clip_name*.gotoAndStop(1);
}

i was hoping that when the newMc expands, all other mc would keep the same distance between each other as at initialisation. I not able to figure how to do it. maybe even an earlier post or llink where similar query was explained.

As most of you don't know, I've been creating an rpg game. And, after several tries of art making, etc, I have finally moved back into coding the game. And now, I'm stuck on the equipment system idea. At first, I thought I would just place a bunch of goToAndStop's for each movie clip to go to a frame that has that certain armor piece. This was my first idea for an equipment system. However, after doing some research, and realizing how much lines of code could be saved, I started looking into simply adding and removing movie clips from the character as my new equipment system idea. Now.... on to the problem.
Basic want/ overall achievement wanted: Create an equipment system, which will basically attach movie clips (items) onto characters, which themselves will already be attached movie clips on the stage.
Problem: What is the exact code to do this? And Is there a better way to do this for an equipment system (a less laggy or more efficient way perhaps that I'm not seeing; Check the code below to get a better idea of what I'm talking about)?
Part of the code (or basic idea of code; see comments for extra details
code:
//Don't worry I have an OnEnterFrame function here;
//attachedObj= the character; figure= the MC name of the character;
attachedObj = attachMovie("figure", "figure"+1, 1);
[Code].....

I have multiple movie clips on stage (all in separate layers, of course) as well as buttons on stage to play each movie clip. There are buttons inside each movie clip. The problem is that the buttons inside the top layered movie clip work, but the others in the movie clips below don't.

In AS3 I am trying to get the distance between 2 3D objects by using distance method.
if(Vector3D.distance(model.position,model2.position) < 100)
{
// do something
[Code]....
>>You can use it directly as a method of the Vector3D class to get the Euclidean distance between two three-dimensional points.
Which point does this method pick? Is it the closest point to the other object ?
I am just thinking of how much time this would take in testing objects with large poly count.

After the dublication of an movie clip,
1. I would like to be able to delete one by one the new movie clips
2. I would like to move them all together.... First you press the word green and then click in the blue area.... A green cyrcle will appear.. Click the word green again and then in the blue square and a new green cyrcle will appear. I would like to move the cyrcles with the buttons arrownd the blue square... And when I press delete I would like to delete any cycle I choose... The flash is too large to attach it to the forum, if anyone is interested I can send it by mail.

I have one simple movie clip (instance name is MC) and a button. I need to make the movie clip move by a distance of 50 (along the x-axis) every time the button is pressed. I don't need the movie clip to move to x-position 50 but rather a distance of 50 regardless of where it currently is on the stage.

Here's what I'm trying to do (in example form): I have a movie clip called "dude". Dude is animated to walk around, then drop a cigar (all inside the movie clip). But the problem is, dude moves, so if you try and move dude as the cigar is dropping, the cigar moves with him. So what I want to do is create a new movie clip instance called "cigar" OUTSIDE of the movie clip dude right as he's dropping it, so that you can move him without moving the cigar. Get it? I've attached another helpful animation to explain.
What I have right now is, on the 13th frame of dude, a few lines of code that create and place an instance of cigar. In that frame I also have an invisible instance of cigar for me to duplicate. Inside of the cigar movie clip is the animation that makes it fall to the ground. I need to change that code so that the instance of cigar is created outside of the movie clip dude. Here's the code I have now (inside of dude, on frame 13):

I have a problem stopping multiple clips. I have created a presentation using flash and I have many movie clips which have sub movie clips inside of them. Ok lets look at one movie clip in detail. Inside one _root movie there are multiple sub movies; each with a different movieclip labels (each movie clip is named with unique labels ie. north, south, east, west, and What I need to do is be able to STOP all these sub movie clips with one stop, and in turn PLAY these same movie clip with a second action.
The only way I know how to stop all these sub movie clips is to target each and every one individually.

Here's the code:
Code: Select allstop();
DontDrive.addEventListener(MouseEvent.MOUSE_OVER, RO_DontDrive);
DontDrive.addEventListener(MouseEvent.MOUSE_OUT, ROut_DontDrive);

I've got a textfield creater that creates a nice textfield when I hover over a moveable button. However, when I click and drag that button around the flash movie, the text field disapears off the edge of the screen if I get to close to the right side. Can I adjust the width of the textfield as the mouse is moving closer to the edge?
