generate spirals

[treatkor]

more spirally goodness.
click to generate a new one, then click again to make another, etc..

can someone check if i'm meeting the <=25 lines requirement? i think i'm counting this right, but i hope i'm not over.

whoa, that's mesmerizing and cool... :thumb: sorry i haven't counted lines...

[jerez_z]

24 lines I think

[ElectricGrandpa]

I counted 23, but if you changed the last part from:

if (c<myRefArray.length) {
c++;
} else {
c = 0;
}

...to...

(c<myRefArray.length)? c++: c = 0;

...you'd save some lines.

Very nice. Very hypnotic and also makes it look like there is a light source at the center point. Perhaps add a Stage.scaleMode = "noScale" into there to make it run faster. It sometimes lags a little bit since its so big.
EDIT: Definately make it smaller! I just resized my window to decrease its size, and it looks so much better with faster movement.

I only count 22 lines as it is. You probably counted the second EnterFrame function declaration too ElectricGrandpa ;)

And although you don't need to , do what EG suggested to save extra lines just in case you want to add stuff to it.

thats nice :)

Cool :thumb:

cool thanks for replies all.

i think i'll do that and add in a Stage.scaleMode="noScale";
thx for the tips.
i've seen some awesome code in this contest.

[treatkor]

geez, after i went back and looked at my code again i realized i'd done a bunch of unnecessary stuff.

so here's a much improved version. should run faster even if you take out the noScale.


Stage.scaleMode = "noScale";
var randomNum = function (Min, Max) {
return Min+random(((Max+1)-Min));
};
var myRefArray = [];
var HH = this.createEmptyMovieClip("HH", this.getNextHighestDepth());
HH._x = HH._y=HH._xscale=HH._yscale=200;
onMouseDown = function () {
startRotate(randomNum(-30, 60), randomNum(-200, 200), 0);
};
startRotate = function (aaa, bbb, c) {
for (p=0, hw=0; p<30; p++, hw=(200/(p+1))+6) {
myRefArray[p] = HH.createEmptyMovieClip("cHH", 2000+p);
var eHH = myRefArray[p].createEmptyMovieClip("eHH", this.getNextHighestDepth()+1);
eHH.lineStyle(0.8, 0xFFFFFF, ((6*p)+6));
eHH.curveTo(hw*Math.cos(aaa), hw*Math.sin(bbb), hw*Math.cos(aaa), hw*Math.cos(bbb));
eHH.curveTo(hw*Math.cos(bbb), hw*Math.sin(aaa), 0, 0);
}
this.onEnterFrame = function() {
myRefArray[c].onEnterFrame = function() {
this._rotation += bbb;
};
(c<myRefArray.length) ? c++ : c=0;
};
};


so i think that's down to 15 lines now for basically the same effect.

Damn, looks really nice, would make an excellent mediaplayer-visualisation.
