o  ar   e ha e learned creating shapes in scratch and a out different  loc s o  scratch.  n
                 this chapter, we will learn about the more blocks of Scratch and creating games in Scratch.

                 Blocks Shapes in Scratch

                  s you must ha e o ser ed  the  loc s in  cratch are in different shapes. They can  e di ided
                 into six types o  shapes. These are   at   tac    oolean   eporter    and  ap.

                 Hat Blocks

                 They are called hat blocks as they look like a hat. We wear a hat on our
                 head, so the hat always comes on the top. Similarly, hat blocks always
                 come at the top of a script as they start a script. This means that you
                 cannot place any blocks above them.

                 Stack Blocks

                 Stack blocks are the most used  loc s in  cratch. They per orm
                 the main commands. Stack blocks have a bowl shape cut on the
                 top and a  ump at the  ottom. This ma es it easier to stac  other  loc s a o e and  elo  them.

                 Boolean Blocks

                 Boolean blocks are condition blocks which return the values “true” or
                 “false” or the number “0” or “1” depending on how they are used in the
                 script.
                 Reporter Blocks

                  eporter  loc s can hold  alues   hich consist o  num ers or strings.

                 you as     hat is           it  ill ans er    . They ha e rounded edges.
                 C Blocks

                 As the name suggests C blocks are   shaped. They are also  no n
                 as Wrap blocks. These are loop  loc s to chec  i  a condition is true
                 in the  loc s  ithin the loop. The    loc s are present in the Control
                 blocks category.

                 CAP Blocks

                 The  loc s  that end  scripts  are  no n as  CAP blocks.  They ha e  a
                 notch at the top and a flat  ottom. They are usually the last  loc s in
                 the script. They are also present in the  ontrol  loc s category.

                 Sensing Blocks

                 Sensing blocks in Scratch sense the input from the keyboard or the mouse at the time of
                 execution o  a script.  ome o  the sensing  loc s and their  unctions are gi en  elo

                                           loc  prompts the user to type the input using the  ey oard.  t  aits
                   for the user input. No other block runs at that time.

                                                                           Advanced Blocks & Game Creation     81
