Flash :: Finding Shortest Distance / Route On Map?

Aug 9, 2011

In Actionscript, I'm trying to work out the best way to create the shortest route between two point on the map above. I have all the distances.

Algorithms like A* I dont think are relevant as it is near impossible to work out the heuristic distance.

I thought I could create a big array of all the nodes with the distances to any connected nodes and just iterate through until Ive found the the shortest distance, but this I know is very inefficient.

ActionScript 3.0 :: Calculate The Distance Between Two Points

May 25, 2010

I'm needing this for a current project, so I have been digging around quite a bit (with little luck) on finding the distance between two points VERY fast. Yes, it is quite critical that it be as optimized as possible. I have the basics, Pythagorean Theorem run in different ways, as well as the Point.distance() function.

Performance :: Find Distance Between 2 Points In Fastest Way

Sep 22, 2011

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?

ActionScript 3.0 :: Zoom In And Out - Calculate Distance Between 2 Points In Map

Aug 6, 2009

I am trying to make a program where I put in a bitmap map and then am able to calculate the distance between two points, and I have done that. Now I want to be able to zoom out and still have those two distance calculate the same distance apart, is there a way to do this with AS3 without have to manually scale my code?

For example I don't necessarily want to have to do
var distance = Math.sqrt(dx*dx+dy*dy)/scale...
Reason being is I would have to redo a lot of code.

Generate Random Points With Defined Minimum And Maximum Distance?

Jan 19, 2012

I need algorithm ideas for generating points in 2D space with defined minimum and maximum possible distances between points.

Bassicaly, i want to find a good way to insert a point in a 2D space filled with points, in such manner that the point has random location, but is also more than MINIMUM_DISTANCE_NUM and less than MAXIMUM_DISTANCE_NUM away from nearest points.

ActionScript 2.0 :: Math With Prototypes And Functions - Find The Distance Between Two Points

May 19, 2003

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?

ActionScript 3.0 :: Finding Points On A Circle

Apr 18, 2009

I need to position objects equally spaced, on the perimeter of a circle. Question is: How can i find the points on the circle based on the number of objects i need to position, and how can i translate these points into another movieclip's coordinates? i thought to make a loop, and for each object (based on it's index in the loop) create a line from the center of the circle with a degree of 360/loop length * object index, and find the point where this line crosses the circle's perimeter.

I dont know though, how to actually implement my idea, i dont know the whole 'finding points' area etc, and I am not at all sure that my idea is the most light and effective solution. This thing i'd like to do (i think) is quite a common task, if you want a circular menu, or whatever, but i havent found anything anywhere around that could shed some light...

Flash - CurveTo Function - Finding X And Y Points Dynamically

Basically I'm using the curveTo function to draw some lines for flight paths, what I'm not sure how to do is dynamically finding the curve points, so for example if you look at the ryan air site: [URL]
current_line.graphics.curveTo(curveX, curveY, map.mouseX, map.mouseY);
I need to find the curveX and curveY

Actionscript 3 :: Finding Control Points For Bezier Curve?

May 9, 2011

First i want to say its my first post and i've been diging straight up gold from this site and i love it and everyone out there smart enough to give out solutions.So basically am writing a game and i have bezier curve that controls where an actor moves. Am using only 3 points (start, control1, end) and everything is fine.Now i want to create a bezier curve that passes through a certain point (r1) at t = 0.5 . The problem being that i have my start point, my end point and my point (r1) at t=0.5, and i need to find the control point.

ActionScript 3.0 :: Flash - Finding The Main Points On A Graph?

Mar 17, 2012

This is more of a question of logic than coding.. but here goes. I've got an array of points, and when plotted on a graph in flash it shows something like this:The blue points just highlight the points of each spike. While the red points are points I want to find.My question is, how do I find the red points on each spike?At first I tried sorting through the array for the highest points, but that didn't give me all the red points as some blue points are higher than the red points.Just by looking at the graph I can immediately see the points I need, but it's a bit harder to find those using code..

ActionScript 3.0 :: Get The Distance Between 2 3D Objects By Using Distance Method

Apr 28, 2011

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.

Actionscript 3 :: Calculating Evenly Distributed Points On A Line Of Points

Oct 3, 2011

I have been tasked with trying to create a drawing tool that draws dotted lines as you drag the mouse across the stage. I can easily capture the points on MouseEvent.MOUSE_MOVE and store them in a vector and then draw the points as dots:

The problem is that I need to calculate evenly distributed points on an ever growing Vector of points so I can only draw the line between say every 5th point (say using modulus). I have been battling away with Bezier curve equations both Quadratic and Cubic but still can't quite figure out how to convert my Vector of points into an evenly distributed Vector of Points without sucking the life from the CPU.

AS3 :: Points & Lines - Getting Lines To Follow Points As They Are Dragged?

Jul 21, 2010

I am trying to create a mindmap where the user can drag points about the screen. I have gotten as far as drawing the line via actionscript, and drag+drop the points (defined as movie clips on stage). This is the existing script - I don't know how to get the lines to follow the points. Something to do with ENTER_FRAME or updateAfterEvent?

var line:MovieClip = new MovieClip();
line.graphics.lineStyle(1,1);
line.graphics.moveTo(ptOne.x,ptOne.y);

ActionScript 3.0 :: Distance To A Line?

Jun 19, 2011

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?

ActionScript 2.0 :: Move A MC A Specified Distance?

Nov 22, 2011

I 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?

ActionScript 2.0 :: Distance Of A Circle?

May 20, 2008

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:

IDE :: Dynamic 3D Distance Calculation?

Jan 14, 2009

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)).

ActionScript 3.0 :: Getting The Distance Between Two Movieclips' X Value?

Aug 8, 2010

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.

ActionScript 3.0 :: Percent Based On Distance?

Aug 7, 2010

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.

Tweening Over Distance Not To Specific Point

Oct 27, 2009

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);
}
