PImage imgBird;
void setup()
{
   size(500,400);
   imgBird=loadImage("bird.png");
   imageMode(CENTER);
}
float birdX=100,birdY=300,oldX,oldY,vx=0,vy=0;
boolean bMoving=false;
void draw()
{
   background(255);
   image(imgBird,birdX,birdY,100,100);
   if(bMoving)line(mouseX,mouseY,oldX,oldY);
   birdX+=vx;birdY+=vy;
   if(birdX>500-50 ||birdX<50)vx=-vx;
   if(birdY>400-50 ||birdY<50)vy=-vy;
}
void mousePressed()
{
   if(dist(mouseX,mouseY,birdX,birdY)<50)
   {
      bMoving=true;
      oldX=birdX;oldY=birdY;
   }
}
void mouseReleased()
{

}
