ActionScript 2.0 :: Determine The Distance Between Two Objects?
Oct 27, 2005how can I determine the distance between two objects?
I need to make an object (A) to follow one other (B) if this one is close to him.
how can I determine the distance between two objects?
I need to make an object (A) to follow one other (B) if this one is close to him.
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.
I am trying to create a scenario where I can have two or more movie clips interact with each other to determine the distance between themselves. I found a script online where it does two movieclips however I need it to do more than two, possibly up to about a dozen. That is the first part. The second part is that I need to be able to select one movieclip and for it to become the "master" and then the other clip determine there distance from the "master". I hope I am explaining this correctly. I have attached the fla file which has the script in it for two movieclips, and then I have modified to add the other clips but not sure of the coding to make it work.
View 5 RepliesI'm trying to get the distance between two objects. Problem is that both objects are -45º rotated but one of them moves up and down with stage resize. So the distance gets a random degree. I've attached an image so that it could be simpler to understand my problem.
View 3 Repliesi am trying to develop a simple car game, and to do that i have to maintain the distance between the two wheels. for the collision detection i have used coreyoneil class, which i think is excellent. i cant get the distances to go smoothly. and basically i am finding it hard to get the physics to work.
p.s. i tried to upload the files here and got an error each time, anyone know why that is?
Is there a way to duplicate objects, like lines across the screen quickly without using AS3 at a fixed distance apart? I tried using Ctrl+D but it has a distance for 7 pxl apart. I want to change that to 1 pixel. Is there a way to change this setting or a tool in flash IDE to perform duplicating quickly?
View 1 Replies often seen in simple flash games. So you can look at an example. http:[url]....Green object shots a bullet and what i want to acheive is to run bullet toward black bar even if bullet is shot to the left side of the screen. Bullet should make a circle, slow down and change direction to the bar and finally proceed faster and faster to the bar. Simply it should behave like remote control rocket chasing enemy. Right now i am with this: Code: Select all
function movingBull(e:Event):void [code].........
//of course i dont know what should be inside if statement
//to make the code work.
Here is my code:
function createEnemy(event:TimerEvent):void {
var enemyAppear = new MovieClip;
enemyAppear = new Enemy();
enemyAppear.x = Math.random()*stage.stageWidth;
enemyAppear.y = 285;
[Code] .....
What I am trying to do is spawn a enemy to stage and when it appears on the stage I would like it to move across the stage a certain distance.
Visual Example:
O = enemy, X = original position, Y = new position
O (Spawns @ Location X) X ---------------------------------------------------------> Y
( Moved from location X to Location Y)
Is it possible to place object on stage with positions read from a CSS file?Basically what I want is to create themes for the application. As and when a different theme is selected, xy position, skins and colors of objects should get applied accordingly.How far its practical? If this is not practical could any one suggest a better way of applying theme
View 1 RepliesI am working on the project where everything is based on the distance from the center of the stage. First I made this fla where flash outputs the x and y distance from the center. First problem is that I want to output distance only in positive numbers.
View 1 RepliesI am trying to create a program using random motion of two movie clips and uses hitTest to determine whether the two objects collide with each other. I've gotten hitTest to work with the original movie clips, but when the user loads more movie clips (via a button and duplicateMovieClip):

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.
Can't figure out this. I have 3 points A(305,108),B(311,119) and C(348,172), to find out the distance from B to AC, i use a method found here [URL]..
I then got the distance equals to 131. When I draw AC and B, it appears B is almost on the line (distance <= 1). Am i doing wrong? what does 131 mean?
Is there any difference between: distance = point1.subtract(point2).length; and distance = Point.distance(point1, point2);
View 3 RepliesI cannot arrive at dynamically showing the text in the dynamic text field when I move one any one of the MC on stage.
View 6 RepliesI am working on a project where I have 5 equal sized panels inside of a MC that I am using the following code on the loading of MC:
onClipEvent (load) {
targetx = 650.0;
delay = 8;
}
[Code]...
What I would like to do is ALSO move the panels with left and right arrows that act independently of navigation buttons. So that if you were on panel 2 you could advance to panel 3 or back to 1. Can I assign AS to the arrows to move the MC a specified distance left or right?
I'm building a touchscreen project that consists of flash and max/msp using Olaf Matthes flashserver as bi-directional control.
how I create a function in flash that will provide me with the distance of a concentric circle, so that as it grows I can use trace() to give me a constant stream of it's x & y coordinates?
I've also implemented a collision detection between two or more circles for the purpose of an overlap function. Trouble being that it's not quite working properly. I want the overlap function for the purpose of morphing sounds between the intersecting parts of the circles.
Here's the code I'm using:

Is there a way to calculate the distance between the origin of a movieClip at, say, (x:500, y:0, z:0) and one at, (x:500, y:0, z:50)?? And lets say the vanishing point is (0,0) and the perspective angle is 50.
I know that the eq for finding the distance between two points in 3D space is:
d = ((x1-x2)^2 +(y1-y2)^2+(z1-z2)^2)^(1/2)
the problem is I dont know x2 (the x value of MC2 (the one set at z = 50)).

At first it seemed simple to find out the distance between two movieclips' x values, I could have just done:
Code:
mc1.x - mc2.x
However, What I'm trying to achieve is a movieclip of a person climbing an un-even surfaced wall, and to do this I first want to make sure the x value of the person is always equal to the edge of the wall.
How would I calculate the exact position of wall's edge where the person is touching it? I've attached an image to show what I mean.
I have a vertical list of movieclips added to the stage all spaced out evenly from top to bottom based of the last movieclips position. I also have defined a center Y point which I would like to find out the percentage of each clip away from that center point. The reason for this number is to scale everything from the center point which is scale 1 then they next item from the center would scale to a percentage from the center point. each clips scaling percentage would be based off of how far they are from the center point in each direction. Keeping in mind the center point is always scale to 1. I also want to make sure my scale never goes below 0.3 so the range has to be between 0.3 and 1 my centerY is also not half the height of the content but a number I decide. AS it the content might be 1000 in height but the center point could be set to 300.

I've scanned through the forums, but can't seem to find an answer to my question. I'm trying to move (tween) a movie clip 800 pixels along the x axis (horizontally) when a every time button is clicked. I don't want to move the movie clip to the 800 "x" pixel mark. Yet, I can't seem to move the clip an additional 800 pixels whenever the button is pressed again - it keeps starting from the original spot. I am new to ActionScript...
My code is below:
btnBottom1.addEventListener
(MouseEvent.MOUSE_DOWN, playHandler);
function playHandler(evt:MouseEvent):void {
import fl.transitions.Tween
import fl.transitions.easing.*;
var twTeen:Tween = new Tween(mcbottomFlap1, 'x', Elastic.easeOut, mcbottomFlap1.x, +800, 3, true);
}
I'm trying to calculate the distance between two images (A and F - there are other images between A and F) but I can't seem to figure out how to do it the right way. The image A.x is "(stage/2) - (A.width/2)" and image F.x is "E.x - imgSpace" which is a negative value (all the images x is of negative value to image A.x). In my oppinion the calculation is F.x - A.x and although it might be right I still ned the value to be non-negative.
View 3 RepliesI am trying to do something like this[code]...
Then how do I make it so all the children added are equal distance apart? I know I can set the X coordinates for each one,but I want it so that the objects can be added in any sequence and then be set to equal distance apart.
Not sure this exist, but worth asking you all: is there a built in method to compute the distance between the current mouse position and a given component? If not, is there a simple way to build a function like this that works for components with generic shapes?
View 2 RepliesI'm creating a drag based control in Flex / Flash, similar to a film strip, where an individual can swipe horizontally to scroll through the items. To make the control feel a bit more natural I've added some inertia to slow the scrolling once a swipe has taken place. When first loaded up there will be five items in view with 'x' numbers of items to scroll through with the 3rd item centred and selected.
My problem though is that I want, when animating, a swipe gesture to determine whether an item will end up the middle (3rd position) and adjust its movement calculation accordingly so it docks with the 3rd / centre position. Imagine you perform a long swipe, it flys pasts 'x' amount of items, but as it slows to a stop it elegantly stops with an item centred / in the 3rd position. To do this I believe I need to determine the distance to travel just from the speed value (as time is irrelevent to the user experience, i.e. a longer / stronger swipe would justify a longer animation skimming through the items).
At the moment I'm invoking the animation routine (with inertia) in the ENTER_FRAME event when the user generates a MOUSE_UP event. When they do this, I obtain the speed of drag (by monitoring this beforehand) and then decrement this speed value on each call of the ENTER_FRAME event until it reaches an appropriate value to stop the animation.
Unfortunately all the speed calculations I've seen deal with Speed and Time to determine distance, I just need Speed. Admittedly, my knowledge isn't strong in this area so I might be missing the obvious.
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?
I have a method that takes a "distance" and "angle" parameter. How can I take the angle parameter to get x and y values, and incorporate the distance into that?
I am assuming that I would have to do something with a right angle triangle.
Im trying to create a scrolling image gallery that changes when one hits the button by tweening the images left and right and now I'm trying to find a simple way to limit their movements in AS3.
Currently the images scroll infinitely in either direction. Is there anyway to restrict their movements?
Code:
import fl.transitions.Tween;
import fl.transitions.easing.Regular;
RightArrow_Btn.addEventListener(MouseEvent.CLICK, scrollRight)

And its not just straight geom because we dont know the ACTUAL x value of the second MC. It thinks its at x:500 but when you look it will look farther to the right than 500

if(400<mc.x<450) {trace("WIN DUDE XD")}[
how to make that interval ?!
