Your Aim
to learn about:
Block Shapes in Scratch Sensing Blocks
Variables Conditional Blocks
Use of Loop Blocks Creating a Game
As you must have observed, the blocks in Scratch are in different shapes and
colours. They are used for various purpose like creating shapes and scenes. In this
chapter, we will learn about the various blocks to create a game.
BLOCK SHAPES IN SCRATCH
Block shapes can be divided into six types of shapes. They 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
are the main commands used to perform some actions.
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.
