how do i hide all sprites at once?

how do i hide all sprites at once? im trying to have all my sprites hide at once WITHOUT the tell ---- to ----

Add

indexIndicesDeepIndex script pic (2)

to each sprite and then triggeer the action with

indexIndicesDeepIndex script pic (3)

You can do this

Which is better because you don't need to have a when I recieve [message] in every sprite.

They said without "tell ---- to --" block. dunno why, but they said without.

oh... didn't read that.

hide [ v]
put nothing in that blank and it hyperblocks
edit:oops that is for variables
