I am a newbie in processing and I wish to move a square by using the arrow keys.  Some of my code is below:
 
void keyPressed (){
      if ((keyPressed == true) && (key == CODED)) {
       
        if (keyCode == RIGHT) {
          //if (directionX < 0)
          directionX = 1;
          directionY = 0;
          println ("bush");
         }
        else if (keyCode == LEFT) {
          //if (directionX > 0)  
          directionX = -1;
          directionY = 0;
          println ("lenin");
         }
        else if (keyCode == UP) {
          //if (directionY < 0)
          directionY = -1;
          directionX = 0;
          println ("high");        
          }
        else if (keyCode == DOWN) {
          //if (directionY < 0) 
          directionY = 1;
          directionX = 0;
          println ("low");
         }
      }
   } 

Where am I going wrong???
