CREATING A SCRATCH PROJECT                                                                                      PROJECT 2: CREATING A SCENE

                                                                                                                                            Create the given script and run it by clicking on the Green flag button.
                  As you know, a sprite is controlled by a list of instructions known as code or script.
                  We create scratch programs by putting code blocks together. Let us create some
                  projects in Scratch. Programs are written in Scratch to move sprites in x and y                                                          when    clicked

                  coordinates on the stage area.                                                                                                           move     10  steps
                                                                                                                                                           turn     30  degrees
                  PROJECT 1: MOVING A SPRITE                                                                                                               say     I am a snowman


                  To move a sprite around the stage, we need to learn how to work with Motion
                  blocks. A sprite can be moved a few steps ahead or turned by different angles. Let
                  us now create a project that instructs a sprite to move.                                                                             SAVING A PROJECT                           1  Click on the
                                                                                                                                                                                                 File menu.
                  Step  1     From the Events block, drag a  when            clicked   block.                                               To save a project before closing


                  Step  2       From the Motion block drag a  move            10  steps   block.                                            the Scratch window, follow the
                                                                                                                                            given steps:
                  Step  3     Click on the number box and change it to  move              50  steps   (The number                                                                        2  Select the Save to

                  Step  4     Drag  a     turn     15  degrees      block.  The sprite  will  rotate  15 degrees
                              clockwise. (To change the angle of turn, change the number of degrees

                              and then click on the block to make the sprite turn.)

                  Step  5     Now, click on move 10 steps and change it to  move                50  steps
                  Step  6     Click the       to run your program.
