| Scroll Right () | |
scroll right ()::motion | |
| Category | Motion |
| Type | Stack |
| Introduced in | v152 (2.0 alpha) |
| Removed in | v172 (2.0 alpha) |
The Scroll Right () block was a Motion block and a Stack block in the Scratch 2.0 alpha. The block panned the backdrop horizontally. It was removed late in the alpha.
Benefits
The block is very useful for creating RPG's and other scrolling games. Using Scroll Right () to scroll reduces much lag because to implement scrolling without the scrolling blocks requires scripts in every visible sprite, running all at once.
Example Uses
- Moving the stage when the player decides to move.
when [up arrow v] key pressed scroll up (10)::motion when [down arrow v] key pressed scroll up (-10)::motion when [left arrow v] key pressed scroll right (-10)::motion when [right arrow v] key pressed scroll right (10)::motion
- Moving until reaching a certain destination.
. . . repeat until <(x scroll::sensing) = (100)> scroll right (10)::motion end . . .
