This tutorial explains how to shuffle some items in a [[list]].

== Variables ==
<scratchblocks>
(item that had its position shuffled)
(# of item that is being shuffled)
(shuffle is)
(repeat)
(items that already had their positions shuffled::list)
(shuffle between::list)

set [randomize is v] to []
delete all of [items that already had their positions randomized v]
delete all of [randomize between v]

ask [How many items do you want to randomize?] and wait
set [repeat v] to (answer)
repeat (repeat)
ask [Input an item to be randomized:] and wait
add (answer) to [randomize between v]
end

repeat (length of [randomize between v])//Now for the most important part.
set [# of item that is being randomized v] to (pick random (1) to (length of [randomize between v])
repeat until <not <[items that already had their positions randomized v] contains (item (# of item that is being randomized) of [randomize between v])>>
set [# of item that is being randomized v] to (pick random (1) to (length of [randomize between v])
end
set [item that had its position randomized v] to (item (# of item that is being randomized) of [randomize between v])
delete (item # of (item that had its position randomized) in [randomize between v]) of [randomize between v]
insert (item that had its position randomized) at (pick random (1) to ((length of [randomize between v]) + (1))) of [randomize between v]
add (item that had its position randomized) to [items that already had their positions randomized v]
end
