Block Name              Shape                                   Function

                   Cap Block                                  This block stops the script from functioning. It is

                                        Notch at the top      shaped in such a way that no other block can be
                                        and flat bottom       placed below it.

                  Scratch blocks are divided into different categories based on their functions. In most of
                  these blocks, you can change the value in the block to suit your script. Let us learn about

                  these blocks in detail.
                  Motion Blocks


                  Motion blocks are used to control the movement of a Sprite. They are blue in colour. Some
                  motion blocks need values for coordinates and directions.
                  Coordinates                                                                  Y


                  Coordinates  are  numbers  that  represent  the
                                                                                             3
                  exact location in the form of (X,Y) coordinates,                                      (2,2)
                                                                                             2
                  X is the  Sprite’s  horizontal  position.  The
                                                                                (-2,1)       1
                  Y-coordinate  is  a  Sprite’s  vertical  position.
                                                                                                                    X
                  X  and  Y  coordinates  when  written  together             -3   -2    -1     (0,0) 1  2    3
                  indicate  the  exact  location  or  position  of  the                     -1
                                                                                            -2
                  Sprite on the stage.
                                                                                            -3
                  While  writing coordinates, the  X-coordinate
                  always  comes  first,  and  the  coordinates  are
                  separated by a comma. For example, an X- coordinate of 2 and a Y-coordinate of 2 would
                  look like this: (2, 2). In the very centre of the Stage is a point marked (0, 0), which is called
                  the origin.

                  In the same way, Scratch determines the positions on its screen. Positions are known as
                  pixels in Scratch. The ‘X’ and ‘Y’ positions in Scratch are used to determine the location of
                  a Sprite (object) on the stage.
