So you've always wanted an 'If I receive [broadcast]' block, right? Well, there's no need for an update to Scratch- it can already be made very simply!

Here's the script:

Or:

Code:

When flag clicked
set [variable] to 0
broadcast [name of broadcast]
Forever
If <[variable] = 1>
do script
end if
end forever

When I Receive [broadcast[
set [variable] to 1

Of course, it doesn't need to be 'change x by 1'- it can be anything.

Hope this helps smile

Nice! Although it would still be nice to still have the <when I receive []> block/sensor because it is a bit complicated.

Agreed.

I'm glad you made this. Lots of people want that block and don't know that they can do it this way.

This confuses me sometimes... Why place the variable at 0 if you're just going to broadcast it back to 1? I do see the target though, and I will probably use this in the future, just alternate it a little tongue

I was probably either not there, or was so new to scratch that I didn't understand it at all.

Normally, you won't make a project that immediately broadcasts that- that script was only an example. In reality, you'd probably make something trigger a broadcast, which triggers the fake 'if I receive'.

And that *points to quote* makes more sence. smile

Good tip although I would name the variable something else cause it may confuse people. I refer to putting a sprite's scripting in a single block as "serial" and using multiple scripts as "parallel." The point is that the more parallel you go, the more you need triggers like these to make sure that everything gets done in order. Failure to do so will usually result in some of the weirdest errors you have ever seen, although that alone is often funny big_smile

ps..I have a tendency to avoid broadcasts if I can cause I heard they cause problems online, even though most of my stuff is for offline use lol.
