How do you broadcast a message?

Daniel975

stickfiregames

broadcast [message v] // broadcasts a message

broadcast [message v] and wait // broadcasts a message, and waits for any scripts that receive it to finish

when I receive [message v] // runs the script when the broadcast is sent

Daniel975

It doesn't work

How do you make a message?

oriole92

The block

broadcast [message v]

will send a message through the project and notify scripts that an event has happened. This can be used to send information between sprites in a game:

when I receive [message v] //This block will activate when the message is received!
say [I have received the message!] for (3) secs

This script will make a sprite talk when it receives a message.

Until now, I hadn't known what the block

broadcast [message v] and wait

did. After looking on the Scratch Wiki, I found out that it simply performs the same function as the block

broadcast [message v]

with one simple change– it freezes the script and does not let it continue until the receiver script is finished.
I hope I was able to help you understand the broadcast blocks better!

To create a message, you click on the dropdown menu on the broadcast block. Then, you click on the “new message…” option that you'll find. Name your new message, and then you can start broadcasting and receiving that message!

example:
first sprite:

when green flag clicked

broadcast [ v]

second sprite:

when I receive [ v]

say [] for (2) secs

hope this helped!

You can find out the meaning of any block by picking up “BLOCK HELP” icon, & clicking on any block.

titanscratch

when green flag clicked
broadcast [a message v] // the script will keep going without any stopping
Other code... ::grey

when I receive [a message v] // receiving script
say [] for [5] secs
Other code... :: grey

Now this is the meaning of this block:

when green flag clicked
broadcast [a message v] and wait // this script will not go on until the receiving script finishes
Other code... :: grey

when I receive [a message v] // receiving script
say [] for [5] secs
Other code... :: grey

I hope I helped.

It is in the EVENTS it says: Broadcast (MessageName) and wait or Broadcast (MessageName)
Kinda like:

broadcast [ v] and wait

Scratch. This is BluesClues2004. Can you help me please. I kept on getting errors on whenever I go to a project I recently made. Can you fix that?

This forum is for scripting problems. We're not Scratch Team members, just volunteers.

So is this a scripting problem or something else? Which project?

Please don't thread hijack. Create your own topic if you have a question.

This block will broadcast it:

when I receive [message]

press the arrow, click new message, name i, press okay.

Then put this block somewhere:

when I receive [message]

You put two when I recieve blocks, and forgot the broadcast block.

Anyway, to answer the question, use:

. . .
broadcast [whatever v]
. . .

in your sprite code to broadcast a message across the entire project. Then, to receive that broadcast:

when I receive [whatever v]
. . .

Broadcasts go everywhere in the project, so this is useful more making one sprite do stuff with another sprite.
