The Y scroll block's appearance in Scratch 3.0.
The Y Scroll block was a Sensing block and a Reporter block in the alpha version of Scratch 2.0. The block reported how far up the stage was scrolled. If it had been scrolled down, a negative number was returned. It was removed late in the alpha.
When the block was originally introduced, it was a motion block. This lasted for two version before the block was changed to a Sensing block in v154. When obsolete blocks were added in 3.0 for compatibility as hidden blocks, the block was re-introduced as a motion block rather than a Sensing block.
Example Uses
- Changing the color of the stage depending on the scrolled y position.

- Setting a message depending on the scrolled y position.
when gf clicked set [message v] to [] forever if <(y scroll::sensing) > (100)> then set [message v] to [This is the beach.] else set [message v] to [These are the hills.]
