Hey guys and gals,
So I started folling around with the MX random motion tutorial, and I really like it. I would like to take it a few steps further. Iโm rather new to raw actionscripting so I have no good idea how to code this on my own. Anyway, this si the code I have now:
function getdistance(x, y, x1, y1) {
var run, rise;
run = x1-x;
rise = y1-y;
return (\_root.hyp(run, rise));
}
function hyp(a, b) {
return (Math.sqrt(a_a+b_b));
}
MovieClip.prototype.reset = function() {
//specify the width and height of the movie
width = 550;
height = 400;
//-------------------
var dist, norm;
this.x = this.\_x;
this.y = this.\_y;
this.speed = Math.random()\*1+0;
this.targx = Math.random()\*width;
this.targy = Math.random()\*height;
dist = \_root.getdistance(this.x, this.y, this.targx, this.targy);
norm = this.speed/dist;
this.diffx = (this.targx-this.x)\*norm;
this.diffy = (this.targy-this.y)\*norm;
};
MovieClip.prototype.move = function() {
if (\_root.getdistance(this.x, this.y, this.targx, this.targy)\>this.speed) {
this.x += this.diffx;
this.y += this.diffy;
} else {
this.x = this.targx;
this.y = this.targy;
if (!this.t) {
this.t = getTimer();
}
if (getTimer()-this.t\>0) {
this.reset();
this.t = 0;
}
}
this.\_x = this.x;
this.\_y = this.y;
};
This what I want to do:
1. Eliminate the small pause each object makes before it begins moving in a new direction.
2. Instead of moving in a straight line from point A to point B, I want each object to kinda move around more naturaly, adding in gradual arcs and turns and what not.
3. I want the objects to bounce of each other
4. I want the objects themselves to scale by their X and Y values.
Iโm probably biting off more than I can chew with this oneโฆ but any help will be greatly appreciated ๐ Thanks!
Feral

Hi feral
Maybe this will help you - itโs one of my old Flash 5 collision experimental. I will update it soon. ๐

I updated the script - now itโs mx compatible. ๐
