-Warning! Noob-
I am creating a banner with a “moving target”, but the target keeps moving under the copy text of the banner, making it illegible.
here is my random movement code (Swiped from kirupa if I recall :D) :
//special thanks to Suprabeener for the code
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() {
//specify the width and height of the movie
width = 300;
height = 180;
//-------------------
var dist, norm;
this.x = this._x;
this.y = this._y;
this.speed = Math.random()*25+25;
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>250) {
this.reset();
this.t = 0;
}
}
this._x = this.x;
this._y = this.y;
};
I have tried modifying the " width = 300;
height = 180;" line, but it does not seem to be changing much, if anything.
I am trying to bound the random movement to the bottom 180 pixels of the composition.
Any pointers or resources would be great, thanks!!!
