For multiple command if structures, use brackets. Here: 
if(Greenfoot.isKeyDown("up"))
  setLocation(getX() , getY()-3 );
only one command (on line 2, in this case) is conditionally executed by line 1. With the following , you can insert as many commands as you want at line 3 and all will be conditional to line 1: 
if(Greenfoot.isKeyDown("up"))
{
    // multiple commands here
}
