Can anyone help me to change direction of this object ? What functions do I need to do to change direction of an object, the object should not move but when you change the values it changes direction left to right. Should I be using the "if" function ?

Any help would be appreciated.

void setup () {
 
  size (250,250);
 
 
}
 

void draw (){
 fill (144,144,144) ;
 ellipse (75,75,55,35);
 triangle (47.5,75,27.5,55,27.5,95);
 fill (255);
 ellipse(86,65,8,8);
 fill (0);
 ellipse (86,65,4,4) ;

}
