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.

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.
I am not sure how to display the distance between the 2 objects on stage dynamically when they are dragged.

View 5 RepliesThis 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?

View 7 RepliesI 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.
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?
View 4 RepliesI am creating a game in which I draw a series of polygons by creating points around a radius of a cricle.
Later on I rotate the shapes and I need to calculate the new location (X,Y) of the points based on the rotation. I have the Old XY of each point, the XY of the center of the shape, radius of shape and the rotation.
Have a look at my diagram of the problem.

Which point does this method pick? Is it the closest point to the other object ?

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.
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);

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?
I cannot arrive at dynamically showing the text in the dynamic text field when I move one any one of the MC on stage.

I'm building a touchscreen project that consists of flash and max/msp using Olaf Matthes flashserver as bi-directional control.

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.

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)).
