Scratch

Minecraft should have nothing to do with programming in Scratch.

do you mean if sprite 1 passes the block, the block does something?

If so, then you could use this:

when gf clicked
wait until <([x position v] of [sprite1 v]) < (x position)>
do whatever you want done before it passes the block
wait until <([x position v] of [sprite1 v]) > (x position)>
do whatever you want done after it passes the block

when gf clicked
forever
if <touching [sign v]?>
say [I am an info block! Use the arrow keys to move!]
else
say (leave this blank)
end

You're most welcome.
