What I am trying to do with AS3 in Flash cs4 is calculate the cursor's distance to given point (let say 400,300) and use that distance to constantly (20 fps) change my curtain's alpha value. (which is basically a box turned into a movie clip) [code]...

How to detect the distance of the mouse movement in a certain time. I'd like to be able to calculate the distance the mouse was moved from one point to another in certain time (one second) and compare these values.

I'm creating a game in flash for a university project, and learning actionscript and programming as I go. I'm very much still at a beginner level - at the moment al I have is some actionscript for drawing rectangles and moving them about the screen. This is what I'm having trouble with at the moment: I have a class called 'Creature', and I want instances of it to interact with each other. I want them to do something when they come within a certain distance of another instance. And I want them to be able to pick a random other instance to get the location of, in order to do something with that information.
What I think I need is: A function for telling the distance between two (x,y) points.
A way of referencing the nearest other instance of the class. And a way of randomly selecting from all of the instances of the class.
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.
View 11 RepliesI am not sure how to display the distance between the 2 objects on stage dynamically when they are dragged.
View 5 RepliesI 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.

View 2 RepliesI'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);
}
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.

From the Robert Penner code given in this tutorial: [URL] i was wondering why controlx and controly has to be so complicated. I've tried changing it to just _root._xmouse but it messes up. I don't get this, shouldn't the curve point be the same point as the mouse?
View 13 RepliesNot 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 0 RepliesI 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.

I 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'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;

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.
How would you calculate or determine the mouse speed on the stage? What i am trying to do is this:
You have a custom cursor which shows a plus sign when you very suddenly and fast change the direction of the mouse to the right. When you do the same to the left, the cursor changes to the minus sign.
However, if you steadily move the mouse from left to right while the mouse cursor is showing the minus sign, the mouse cursor stays the same, only on very fast change of direction the cursor changes?
How can I calculate the angle of a 3d object based on the mouse speed?I want to change the rotationZ state based on the mouse position.

>>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.
