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.
