Breakable loop in Scratch ?

How do you make a breakable loop in Scratch? I'm using Scratch 2.0 and can't find any good way to make a loop breakable, from inside of the loop itself.

 

Disclaimer:

There is no perfect way to do it. If you can possibly stand this true fact then feel free to continue.

There are a few different ways you could do it.

With repeat until

The first and most simple one follows this:

But this isn't technically part of the script - it's just repeating until some value returns true.

With a custom block (stop this script)

In order to do it inside of the script, you'll need to use a sneaky little trick with custom blocks.

Create a custom block called whatever you want - but probably along the lines of "breakable loop". Inside of it, create this script:

By using stop script we are breaking out of the script that is currently running - which, according to Scratch, is the custom block.

With broadcast and wait

You could also use a broadcast-and-wait method, very similar to above:

Though I highly suggest you don't use this method, as if any other sprites have breakable loops you'll need to rename each one, which can be tedious after using a lot of loops in a lot of sprites!
