Aryan: Variables? What are these variables, dear? It’s a new word for me.

Gowri: Yes, sure dear! I know, it’s a new word for you. I will explain now its meaning to you.
Variable means varying and varying means changing. So a variable is a name, which stores some
value and its value can be changed at any time.

Aryan: Please tell me more about it also with the help of examples.

Gowri: Yes, sure, dear! We can learn this topic by the following blocks.

6.2 CREATE VARIABLES AND CHANGING THEIR VALUES—

“VARIABLES” BLOCK

6.2.1 “Make a variable’’ button
This is a button in Variables block used to create a variable with a name given by
us. Once a variable is created, it can be used by either a single sprite or all sprites,

depending on how it is set up. When we click on “Make a variable” button, then a
window appears as shown in Fig. 6.6 (having more details to learn it). E.g. create two
variables named “score” and “life”. “score” variable is used to count, number of times

“missiles” hits the planet and destroys it. “life” variable is used to count, number of
times planets hit the “spaceship” and decreases its life, which is decided as 5 as per
the game criteria.

Gowri: We can also store any value in this variable.

Aryan: How can we give values to this variable and also change its
value?

Gowri: Yes, dear! Let’s learn it now.
