void setup(){

  size(600,800);

}

int flying=0;

float eggX=300, eggY=600, eggVX,eggVY;

void draw(){

  background(0);

  ellipse(eggX,eggY, 100,100);

  if(flying>0){

    eggX+= eggVX;  eggY+= eggVY;

    flying--;

  }

}

void mouseDragged(){

  eggX=mouseX; eggY=mouseY;

}

void mouseReleased(){

  flying=30;

  eggVX= (400-eggX)/30;

  eggVY= (200-eggY)/30;

}
