                                                     Points the sprite towards the mouse pointer.

                                                     Changes the sprite’s X position by the specified number of
                                                     steps.

                                                     Sets the sprite’s X position to the specified value.



                                                     Changes the sprite’s Y position by the specified amount.

                                                     Makes the sprite bounce back when it touches the edge of the
                                                     screen.

                                                     Changes how the sprite rotates.

                                                     Reports the sprite’s current Y position.


                                                     Reports the sprite’s current direction.


                  Example 1: Moving and turning a sprite
                  Follow the given steps:
                  Step 1:   Drag and drop the when clicked block from the Events category.
                  Step 2:   Drag the move with 10
                            steps and drop it below
                            the    when     clicked
                                                                             1
                            block.
                  Step 3:   Drag  the  turn  block
                                                                                     2
                            and  change  its value
                            to  90 degrees.  The
                            sprite moves  10  steps                         3
                            forward and then turns
                            90  degrees  when  the
                            green  flag  is  clicked,
                            causing  the  Cat  sprite
                            to  rotate  and  change
                            its position on the
                            stage.
