Category Control
Type Cap/Stack
(changes depending on argument)
Introduced in 2.0

The Stop () block is a Control block. Depending on the option chosen in the dropdown, it is either a Cap block ("all" or "this script"), or a Stack block ("other scripts in sprite"). It is the only block that changes its shape. It was added in Scratch 2.0 to replace the Stop All and Stop Script blocks, and also to add the functionality of stopping other scripts in a sprite. If there are blocks below it and it is a stack block, the other options in the dropdown will be missing.

Options

  • all - stops all scripts in the entire project. This has the same behavior as clicking the stop sign
  • this script - stops the script the block is in. When using this mode inside of a custom block, it will resume the script the custom block was run from.
  • other scripts in sprite - stops all scripts in the sprite this block is in except the script the block is running on
Note Note: this mode turns the block from a cap block to a stack block

Example Uses

stop [other scripts in sprite v]::stack
The Stop () block as a stack block

This block can be used in some of the following ways:

  • Ending a project once all the actions are carried out
when I receive [end v]
say [That's all folks!] for (2) seconds
stop [all v]
  • Stopping a project — when all lives are lost, for example
when gf clicked
forever
if < (lives) = [0] > then
stop [all v]
end
  • Disabling controls
when gf clicked
forever
if << key (up arrow v) pressed? > and < (jumping) = [0] > > then
set [delta-y v] to [5]
end
if < (level) = [7] > then
stop [this script v]
end
  • Disabling a sprite
when gf clicked
forever
if < (x position) > [100] > then
stop [other scripts in sprite v]
stop [this script v]
end
  • Only performing an action a certain amount of times, and then stopping
when gf clicked
set [x v] to [0]
forever
if < (x) = [5] > then
stop [this script v]
end
move (10) steps
if on edge, bounce
change [x v] by (1)
  • Implementing recursion-based procedures (as an end condition)
define factorial (n)
set [result v] to (n)
set [counter v] to ((n) - [1])
forever
if < (counter) > [1] > then
set [result v] to ((result) * (counter))
change [counter v] by [-1]
else
stop [this script v]
end
end

when gf clicked
factorial (5)
say (result) for [2] seconds // The main script will not stop because the "stop this script" block is in the "factorial" block, and it will not interfere with the main script.
