I have a question about scratch sprite coverage. Does the sprite range contain the backdrop?

Not sure exactly what your question is.

The backdrop is the very back layer in Scratch. You cannot move it but you can give it a costume.
You can write scripts for the backdrop including “when backdrop clicked”.
(Click the backdrop icon (rectangle) below the stage in the Scratch Editor to write scripts for the backdrop).

Sprites will always be in front of the backdrop.
If a sprite is big enough it can cover and obscure the whole backdrop.

You can have a sprite larger than the backdrop and it is possible to make sprites go off of the backdrop (though that’s a bit more tricky), if that’s what you were wondering

Thanks for the answer.
For a detailed question, I saw an article on the internet that says a backdrop is a type of sprite because it can assemble blocks. So is the backdrop included in the sprite?

No, the backdrop is an un moveable backdrop for your game, when you create a new sprite it does not include the backdrop.

Hi mickey_choi,

It isn't possible to insert backdrops into sprites if that's what you mean, and it's also not possible to make backdrops move. The only way to make a moving backdrop is to create a white backdrop, and then make a sprite that's as big as the backdrop and give it some art, and then put it on the white backdrop. You have a moveable backdrop already!

Hopefully this helps,
Nammy
