Introduced in 1.2

The () of () block is a Sensing block and a Reporter block. The block will report a specified value of the specified sprite or the Stage.

Below are the values that can be reported:

Example Uses

This block allows sprites and the Stage to have access to other sprites' special values. With this, projects can have a lot of connectivity between sprites.

This block renders eight blocks unnecessary:

Also, as of Scratch 1.4, the SpriteName area can have an expression/variable put into it so that a script can access any other sprite's variables or properties given that sprite's name. This is useful in projects where one wants to be able to generalize things:

set [index v] to [0]
repeat (length of [names v])
   change [index v] by (1)
   replace item (index) of [values v] with ([myVar v] of (item (index) of [names v]))

Some common uses for the () of () block:

  • Making a sprite follow another by setting their X and Y positions to the X and Y positions of the other, plus or minus a certain amount:
when gf clicked
   go to x: (([x position v] of [Sprite2 v]) - (10)) y: (([y position v] of [Sprite2 v]) - (10))
  • Waiting for a different sprite to reach a certain costume
wait until <([costume# v] of [Sprite2 v]) = (target)>
  • Checking volume to adjust a sprite's own volume accordingly
set volume to ([volume v] of [Sprite2 v])%
