I can't get the object to bounce of the sides.

Without sounding cliche, Hi I'm new and I need help :)
I'm trying to make the object (in this case a silly alien thingy) bounce of the bounds of the screen. I've followed the tutorial and example and yet I can't seem to get it to work. Its supposed to bounce on the position of the hat and the shoes.

void drawhat(){

rectMode(CENTER);

fill(random(255), random(255), random(255));

hatbrimxloc = facexloc;

hatbrimwidth = facewidth + facewidth/2;

hatbrimheight = faceheight / 10;

hatbrimyloc = faceyloc - (faceheight / 2) - (hatbrimheight - faceheight/5);

//hat

hatbodyxloc = facexloc;

hatbodywidth = hatbrimwidth - 200;

hatbodyheight = faceheight/2;

hatbodyyloc = hatbrimyloc - (hatbrimheight / 2)- (hatbodyheight / 2);

} //end hat

void drawleftshoe(){

//left

leftshoecorner1xloc = facexloc - 30;

leftshoecorner1yloc = faceyloc + (faceheight / 2) - (faceheight / 40);

leftshoecorner2xloc = leftshoecorner1xloc - facewidth/2;

leftshoecorner2yloc = leftshoecorner1yloc + (faceheight /6) ;

fill(random(255), random(255), random(255));;

rectMode (CORNERS);

rect (leftshoecorner1xloc, leftshoecorner1yloc, leftshoecorner2xloc, leftshoecorner2yloc);

}//end left shoe

void drawrightshoe(){

rightshoecorner1xloc = facexloc + 30;

rightshoecorner1yloc = faceyloc + (faceheight / 2) - (faceheight / 40);

rightshoecorner2xloc = rightshoecorner1xloc + facewidth/2;

rightshoecorner2yloc = rightshoecorner1yloc + (faceheight /6) ;

fill(random(255), random(255), random(255));

rectMode (CORNERS);

rect (rightshoecorner1xloc, rightshoecorner1yloc, rightshoecorner2xloc, rightshoecorner2yloc);

} //end right shoe

// end shoes

void move (){

int upperboundry = hatbodyyloc + hatbodyheight/2;

xdirection = random (1,5);

ydirection = random (1,5);

xspeed = random (1,5);

yspeed = random (1,5);

facexloc = facexloc + ((int)xspeed * (int)xdirection );

faceyloc = faceyloc + ( (int)yspeed * (int)ydirection );

//end moveybit

//left + right

if (LeftX2 <=0 || RightX3 >= width){

xdirection *=-1;

}//end if l+r

//up+down

if (upperboundry <=0 || rightshoecorner2yloc >= height){

ydirection*=-1;

}

if (RightX3 >= width || LeftX2 <=0) {

xdirection*=-1;

}

}//end move
