{{obsolete feature}}
{{other version|1.4|3.0|2.0}}
{{warning|This script will close Scratch without saving one's work. Be sure to save before testing this.}}

It is simple to make a [[project]] that closes when the [[Green Flag]] is clicked. This has been one way users try to [[Project Downloading#Locking Downloads|prevent]] [[remix]]ing, though it is actively discouraged by the [[Scratch Team]]. It has also not been successful, as you can open a remixed project without ever pressing the [[Green Flag]]. This is called '''making Scratch crash'''.

== Method 1: Variables ==
# Create a project.
# Make a [[Variable#Local Variables|local variable]] called "variable".
# Add the following code to a sprite:
<scratchblocks version="2.0">
when gf clicked
hide
set [variable v] to [2]
forever
set [variable v] to ((variable) * (variable))
set [variable v] to ((variable) * (variable))
end
</scratchblocks>

Or

<scratchblocks version="2.0">
when gf clicked
hide
set [variable v] to [2]
forever
change [variable v] by ([10 ^ v] of (variable))
end
</scratchblocks>

Or

<scratchblocks version="2.0">
when gf clicked
hide
set [variable v] to [12]
forever
set [variable v] to ((variable) * (variable))
</scratchblocks>

=== Explanation ===
This [[script]] will fill [[Smalltalk|Squeak]]'s memory, and will force it to close. Squeak automatically crashes when a [[variable]] reaches a very high amount as it does not have the memory to maintain it. Since Scratch runs within the Squeak environment, Scratch closes when the Squeak environment closes. If a high RAM has been allotted to Scratch or if this is tested on Scratch 2.0, it may just say "Infinity", and not close.

== Method 2: Graphic Effects ==
# Get into the [[Scratch 1.4 Source Code]] and open the [[System Browser]].
# Add <code>'water ripple'</code> near the rest of the graphic effect names in <code>Scratch-Objects >> ScriptableScratchMorph instance >> looks ops >> graphicEffectNames</code>
# Save the changes and close the System Browser.
# Drag out a [[Set () Effect to () (block)|Set () Effect to ()]] block and choose "water ripple" from the dropdown and set the value to 1 or higher. When the block is clicked, it will crash Scratch. Note that Squeak doesn't have enough memory to run the effect, so it crashes instead.<ref>[[projects:1504686]]</ref><ref>[[scratch:static/projects/rubiks cube guy238/1504686.sb]]{{dead link}}</ref>
<scratchblocks version="2.0">
when gf clicked
set [water ripple v] effect to ((1)/(0))
</scratchblocks>

== Method 3: Hacked Block ==
# Get into the [[Scratch 1.4 Source Code]] and open the [[System Browser]].
# In <code>Scratch-Objects >> ScriptableScratchMorph class >> block specs >> blockSpecs</code> add <code>('close Scratch' #- #closeScratch)</code> at the end of the <code>'control'</code> section
# Add the following in <code>Scratch-Objects >> ScriptableScratchMorph instance >> other ops</code>
<pre>closeScratch
Smalltalk snapshot: false andQuit: true</pre>
# Save both the changes and close the System Browser.
# Drag out the close Scratch block that was just made, and run the block. Instead of crashing, Scratch closes without a warning.
<scratchblocks version="2.0">
when gf clicked
close Scratch :: control
</scratchblocks>
