                  Your Aim


                  to learn about:
                       l  Block Categories       l  Setting the Sprite Position



            You  know  that  Scratch  blocks are  divided into  different  categories.  Each  block
            performs a different function. Let's learn more blocks of Scratch in detail.

                BLOCK CATEGORIES

            The blocks in Sprite 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.



                    Motion   Looks   Sound    Events  Control  Sensing    Operators  Variables  My Blocks
            Motion Blocks


            The blocks that are used to control the movement of a Sprite are known as Motion
            blocks. They are blue in colour. Some of the commonly used motion blocks are:

                move  10 steps  block lets the Sprite move forward (in the direction it is facing) the

               number of steps given in the text box in the block. When we write the value with
               a minus (–) sign, the Sprite moves backward, e.g. move – 10 steps  move               –10 steps .

                 turn  15  degrees   block lets the Sprite turn in  clockwise direction by the given

               degrees and  turn       15  degrees  block turns Sprite in anti-clockwise direction by
               the given degrees.

                 To make a Sprite jump to a new position on the stage, use               go to x: 0  y: 0  block.
               This block gives the x and y position of the Sprite on the stage.

                 Use   go to mouse-pointer   to tell the Sprite to follow one of the two given options: the

               mouse pointer or a random position.
