I’m beginer and I really need help with action script.
I have this script from tutorial:
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(aa+bb));
}
MovieClip.prototype.reset = function() {
width = 550;
height = 400;
var dist, norm;
this.x = this._x;
this.y = this._y;
this.speed = Math.random()*4+2;
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>1000) {
this.reset();
this.t = 0;
}
}
this._x = this.x;
this._y = this.y;
};
I’ve tried to change it but it was too hard for me.
I need it to work like matrix motion. Move down and for example on y=400 disappear -> appear on starting y position and start random motion down again.
Please help and sorry for my bad english.
If you need more precise information just tell me.
