    So  far,  we  have  learned  about  creating  shapes  from  scratch  and  about  different
                     blocks of scratch. In this chapter, we will learn about the more blocks of Scratch and
                     creating games in Scratch.

                     Blocks Shapes in Scratch

                     As you must have observed, the blocks in Scratch are in different shapes. They can be
                     divided into six types of shapes. These are: Hat, Stack, Boolean, Reporter, C and Cap.

                     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  blocks  in  Scratch.
                     They perform the main commands. Stack blocks have

                     a bowl shape cut on the top and a bump at the bottom.
                     This makes it easier to stack other blocks above and below 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

                     Reporter  blocks  can  hold  values,  which  consist  of  numbers  or

                     strings. If you ask, “What is 3 + 3 ?”, it will answer “6”. They have
                     rounded edges.

                     C Blocks

                     As the name suggests C blocks are C shaped. They are also known
                     as Wrap blocks. These are loop blocks to check if a condition is

                     true in the blocks within the loop. The C blocks are present in
                     the Control blocks category.

                     CAP Blocks

                     The blocks that end scripts are known as CAP blocks. They have a
                     notch at the top and a flat bottom. They are usually the last blocks
                     in the script. They are also present in the Control blocks category.

                                                                               Advanced Blocks & Game Creation    73
