So far, we have learned creating shapes in 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.

            Sensing Blocks

            Sensing blocks in Scratch sense the input from the keyboard or the mouse at the time of
            execution of a script. Some of the sensing blocks and their functions are given below:

                                      block prompts the user to type the input using the keyboard. It waits
               for the user input. No other block runs at that time.

                                                                      Advanced Blocks & Game Creation     81
