(Redirected from (X Position))
- This article is about the block. For more information on the value this block reports, see X Position (value).
As this block holds its sprite's X position, it can be used when a script needs to know its sprite's X position. There are many cases of this — for example, you could use the block to detect how far left or right you are on the screen.
forever wait until <(x position) > > change [Hits v] by (1) end
Another use is setting values based on a movable slider without using Scratch's default slider — the script sets the value to the slider's X position.
set [worms v] to (x position)
Other common uses are:
- Comparing the X position with a record to check for movement
when green flag clicked set [x_pos prev v] to (x position) forever if <not <(x_pos prev) = (x position)>> then say [My X position moved!] for (2) secs //if the x position moved, say something set [x_pos prev v] to (x position) end end
- Constantly storing a sprite's X movement so it can be re-enacted later
when green flag clicked //script only works in a sprite! delete (all v) of [x positions v] delete (all v) of [y positions v] say [Move your mouse and I will reenact the movement!] for (2) secs say [Go!] for (1) secs repeat (50)//records 50 coordinates at a rate of one for every 0.1 seconds add (mouse x) to [x positions v] add (mouse y) to [y positions v] wait (0.1) secs end set [counter v] to  say [I will reenact it for you now!] for (2) secs repeat (50) go to x:(item (counter) of [x positions v]) y:(item (counter) of [y positions v]) wait (0.1) secs change [counter v] by (1) end
- Changing a sprite's speed based on its coordinates

The block can be simply replicated with the following block:
([x position v] of [wanted sprite v])
