Swarming

[JerryScript]

I've was messing around with eliptical orbits, and came up with a basic swarming prototype. I created it in Ming, so it may need a bit of tweeking for the Flash IDE. Example (http://jerryscript.hostrocket.com/flash/examples/particle/swarm-html.php)

MovieClip.prototype.swarm=function(sides,start,cha nge){
this.c=start;
this.bs=start-180;
this.bsc=change;
this.bsx=1;
this.ly=0;
this.fly=this.flyout=0;
this.sides=sides;
this.frozen=0;
this.onEnterFrame=function(){
if(this.frozen==0){
if(this.flyout<2){this.flyout+=0.01;}else{if(Math.round(Math.rand om()*200)==1){this.flyout=0;}}
this.fly=(this.flyout<1)?2-this.flyout:this.flyout;
this.clear();
if(this.c<=360){
if(this.bs<-180 || this.bs>180){this.bsc*=(-1);}
if(this.bs>180){this.bsx*=(-1);}
this.bs+=this.bsc;
if(this.bsx<0){this.xx=this.bs;this.yy=180;}else{this.xx=180;t his.yy=this.bs;}
this.moveTo(this.x,this.y);
for(a=0;a<=10;a+=2){
this.lineStyle(a,0xaaaaaa,a/10*100/4);
this.x=Math.sin(Math.PI/180*(this.c+a))*this.xx/this.fly;
this.y=Math.cos(Math.PI/180*(this.c+a))*this.yy/this.fly;
this.lineTo(this.x,this.y);
}
this.c+=360/this.sides;
}else{
this.c=0;
}
updateAfterEvent();
if(Math.round(Math.random()*200)==1 && (this.x*this.x+this.y*this.y)<90*90){
this.frozen=Math.round(Math.random()*40);
}
}else{
this.frozen--;
}
}
}

// example usage, create a light sphere to swarm around
createEmptyMovieClip('sphere',1);
with(sphere){
lineStyle(1,0x0000ff,1);
colors =[ 0xffffff,0xffffff,0xffffff ];
alphas =[ 100,20,25 ];
ratios =[ 0,254,255 ];
matrix ={matrixType:'box',x:-78,y:-78,w:155,h:155,r:(45/180)*Math.PI };
beginGradientFill('radial',colors,alphas,ratios,ma trix );
for(c=0;c<360;c+=6){
x=Math.sin(Math.PI/180*c)*85;
y=Math.cos(Math.PI/180*c)*85;
if(c==0){moveTo(x,y);}
lineTo(x,y);
_x=450;
_y=250;
}
endFill();

// create the swarm, here there are 8 "bugs"
for(m=1;m<9;m++){
sphere.createEmptyMovieClip('dot'+m,1+m);
sphere['dot'+m].swarm(60,Math.round(Math.random()*360),m);
}
}

_root.sphere.onPress=function(){
this.startDrag();
}

_root.sphere.onRelease=_root.sphere.onReleaseOutsi de=function(){
stopDrag();
}

// this will make the sphere flicker and enables scaling
_root.sphere.onEnterFrame=function(){
this._alpha=Math.random()*15+85;
this._xscale=this._yscale=_root.slider._y-200;
}

// create a slider for scaling
_root.lineStyle(4,0xffffff);
for(d=1;d<6;d++){
_root.moveTo(95,d*50+150);
_root.lineTo(105,d*50+150);
}
_root.moveTo(100,200);
_root.lineTo(100,400);
createEmptyMovieClip('slider',100);
with(slider){
lineStyle(5,0xffffff);
moveTo(-10,0);
lineTo(10,0);
_x=100;
_y=250;
}

_root.slider.onPress=function(){
this.startDrag(1,100,200,100,400);
}

_root.slider.onRelease=_root.slider.onReleaseOutsi de=function(){
stopDrag();
}


The slider is for scale, and the shpere is draggable.

transmitting it to the movies section will make it easier to find for others...

anyway, thanx for that.

Thanks for the tip, I guess I'm confused about the sections, never would of thought of posting it to movies :)
