Gowri: Yes, right Aryan, tell me, can we move, turn and fly the sprites. Remind me
the names of the blocks to perform these tasks.
Aryan: Yes, I know this Gowri,

1. “move … steps” block is used to move the sprite forward or in backward
direction.

2. “turn…. degrees” block is used to turn the sprite in the left or right direction
to an angle given by us.

3. “glide...” block is used to fly or float the sprite to a random position or to a

particular (x,y) direction.

Gowri: Yes, you are right Aryan. You also know that sprites can also say a
message and switch its costume as well. Please tell me the names of the blocks
to perform these tasks.

Aryan: Yes, I know this also Gowri, these blocks are: -

1. “switch costume to” or “next costume” block is used to change the costume of
a sprite.

2. “Say…” or “Say… for … seconds” block is used to say any message by the sprite

in a bubble pulled out.
3. “think…” or “think… for … seconds” block is used to say any thinking message

by the sprite in a thinking bubble pulled out.

Gowri: Yes, you are right Aryan. But do you know what is the difference between
“switch costume to” and “next costume” block?

Aryan: Yes, I know this also Gowri, but I have doubts about this topic. So, please
tell me this also to clear this topic more.
Gowri: Ok! Sure Aryan. “switch costume to” block has a drop-down menu and is
used to choose the costume from the list given in the drop-down as per our choice.
But by “next costume” block Scratch automatically chooses the next costume from
the list. We can’t choose the costume-name from our own choice.

Aryan: Thanks, Gowri, for explaining this to me.
