hey guys

i have a open-sorce code by me. Its about fun with classes, it so creates a "painterish" and unique-interactivity. and it still a waves involutes the point based on mouse position.

this is my code

int tfade=0;

involuto[] it;
int nmb=100;

pointer pt=new pointer();

boolean startnow=true;

void setup(){
 size(500,500);
 background(240,222,58);
 
 it=new involuto[nmb];
 
 for(int a=0;a<it.length;a++){
   it[a]=new involuto();
 }
}

void draw(){
 if(startnow){
   if(tfade++>100){
     fill(240,222,58,50);
     rect(0,0,width,height);
     
     tfade=0;
   }
 
   pt.trail(0.0f,0.0f);
 
   for(int a=0;a<nmb;a++){
     it[a].trail();
   }
 }
}

void mousePressed(){
 startnow=!startnow;
}

class involuto{
 float x,y; //base position
 float xp,yp; //position [called by pointer]
 float radmo,themo; //controlled by mouse position
 
 float thtv; //theta velocity
 
 int tm; //timecount
 int tmv=int(random(5,25)); //velocity
 
 float thtm; //time-based theta
 
 involuto(){
   //no constructors here
 }
 
 void trail(){
   xp=mouseX+sin(pt.xp);
   yp=mouseY+sin(pt.yp);
   
   radmo=sqrt(sq(250-xp)+sq(250-yp));
   themo=atan2(250-xp,250-yp)*(180/PI);
   
   thtv=random(-10,10);
   themo+=thtv;
   thtv*=random(0.995,1.005);
   
   tm+=tmv*0.1;
   thtm=tmv*sin(tm);
   
   x=xp+radmo*cos(PI/180*(themo+thtm));
   y=yp+radmo*sin(PI/180*(themo+thtm));
   
   for(int a=0;a<tmv;a++){
     stroke(0,0,0,32);
     point(x-(x-xp)*sin(a),y-(y-yp)*sin(a));
   }
 }
}

class pointer{
 float xp;
 float yp;
 
 pointer(){
   //no constructors here
 }
 
 void trail(float xp0,float yp0){
   xp=xp0;
   yp=yp0;
 }
}

enjoy!
