(x scroll::motion)
The X scroll block's appearance in Scratch 3.0.
The X Scroll block was a Sensing block and a Reporter block. The block reported how far right the stage was scrolled. If it had been scrolled left, a negative number is 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.
