P. 107
We have already learnt how to change the costume of a sprite and to work with two
sprites in previous class. Now, in this chapter, we will learn to create variables and control
the movement of the sprite in a better manner.
What if you could code your own superpower in Scratch? What would
your superpower be, and how would you use it to help others?
VARIABLES IN SCRATCH
Variables are used to hold information such as words or numbers. Variables are named
locations where you can store information. We can create variables for one or for all the
sprites.
GLOBAL VARIABLES
If a variable is created, to be used and modified by all the sprites, then it is known as
a global variable. A global variable can be created on any sprite but its value can be
accessed or modified by other sprites used in the project.
LOCAL VARIABLES
Local variables can only be accessed or modified from the sprite where it was created.
CREATING A VARIABLE
To create a variable, follow the given steps:
4 Select whether the
2 Click on Make block is ‘For all sprites’ or
a variable. ‘For this sprite only’.
3 Type a name
in New Variable
name box.
1 Click on the Variables Block. 5 Click on OK button.
