{{April Fools}}If you have a lot of [[clone]]s with a local variable, they may want to count them automatically, rather than individually assigning each of them a number in a [[set () to ()]] [[Blocks|block]]. With this method, a [[script]] could specifically call the number-seven clone without hard-coding it.

== Method ==
Firstly, a [[Variable#Global Variables|global variable]] <sb>(sprite count)</sb> should be created. Then, on the stage, the following script should be added:

<scratchblocks>
when gf clicked
set [sprite count v] to [0]
broadcast (count sprites v) and wait
. . .
</scratchblocks>

Now, for all the sprites that want to be counted (and generally these will be clones of the same sprite), this script should be added:

<scratchblocks>
when I receive [count sprites v]
change [sprite count v] by (1) // This takes advantage of the fact that scripts are not run at the same time.
set [my number v] to (sprite count) // Swap these two blocks to start count at 0 instead of 1
</scratchblocks>

Then, when the [[Flag (programming feature)|flag]] is clicked, each sprite will obtain a unique number in <sb>(my number)</sb>.

This works because of the [[Broadcast#Execution Order|execution order of broadcasts]].
